The invention relates to the field of hydraulic engineering, in particular to the bed, and aimed at flushing channels of small rivers and irrigation canals, and to improve water quality and General sanitary-hygienic condition of watercourses, increasing the productivity of rivers and their floodplains.

There is a method of flushing channels natural watercourses (Lapenkov B.C. Without small rivers there are no large rivers. - Rostov: Knitd, 1983. - C-84), including the creation of stationary reclamation reservoirs in which to increase drainage capacity, reduce groundwater levels in the floodplain and improve the sanitary condition of watercourses, bed-formation releases water flow carry out washing channels from alluvial deposits.

The disadvantages of the described method of flushing stream channels include technical and organizational complexity of creating and crossing bed-formation expenses, consisting of the construction of reservoirs with large amounts of water and with the whole complex of hydraulic structures (dam, culvert and vodostochnye structures, lacosamide and others).

Closest to the claimed method is a method of cleaning an open channel from bottom sediments (SU A.S. No. 1046397, EV 3/02, BI No. 37 of 07.10.1983), including erosion of sediment by water jets under pressure with subsequent ablation of the stream is m water channel, in order to improve the efficiency of flushing by removing silt fractions and shielding surface of the bottom of the riverbed sand fractions in the bottom layer of thread support current density vodoprochnoi mixture, however vsasyvauschie device containing energy-intensive equipment (pumping)engaged in the formation of high-pressure water jets to scour sediment.

The disadvantages of the method include the difficulty of maintaining in the bottom layer flow estimated density vodoprochnoi mixture across the width of the channel. Vsasyvauschie device for realizing this method has high energy and complex process flow diagram, low operational reliability.

Also known floating, which device Aieta for dredging (SU A.S. No. 553325, EV 3/02, BI # 13 of 05.04.74), made in the form of interconnected flexible airtight containers, filled with air. Transportation device for flushing river rapids implement the use of boats.

The disadvantages of this device include the inability of the flushing channel across the section and making it natural settings, as well as the need to use to move the device power-consuming resources.

The closest, in cha the tee of the claimed device, is a way of deepening and rectify river rapids mobile vodokanalnyh device (SU A.S. No. 256646, EV 3/02, BI No. 34 from 04.11.1969), where Vodocanals device for deepening and rectify the river roll, not reaching to the bottom of the river, made of film-fabric materials and consisting of the pressure of the cloth with the float cable connection and ballast, move through the vessel in the stream to scour sediment.

The disadvantages of this device are limited its application only to correct rifts and the impossibility of cleaning of the bed across the section, as well as the complexity of the process operation in view of the use of the vessel to move the device to the place of flushing.

The task, which is aimed by the invention is the simplification of the flushing channels of natural and artificial watercourses through the use of energy of the water flow.

The technical result - the deepening of the channel, forming a blind area estimated fractions, bed cleaning around the section and giving it a natural parameters, improvement of sanitary-hygienic conditions of the watercourse, improving the productivity of rivers and their floodplains.

The technical result in part of the method is achieved by the fact that the stream set device todopoderoso structures of Dane who's materials, allows you to create the power and ability to control the speed regime to lose alluvial sediments with particle diameters, the smaller diameter of the particles projected blind area with subsequent entrainment their stream of water, and the process of flushing occurs continuously due to the maneuvering of the structural elements of the device, which allows him to move along flushing together with educated them stream flow reservoir.

The technical result in part of the device for hydraulic flushing channel is achieved by the fact that to create in the direction of the velocity, scour alluvial sediments with subsequent entrainment their flow of water, the device is made of horizontal panels, with the installed ballast connected to the pressure panel cable connections to form between them culvert slit along which the panels are fixed cylinders, adjustable using a placeholder, the value of the opening of the slit is adjustable overlapping its movable panel that is attached with a stabilizing rings for cable connections along the longitudinal wave moving cloth is attached to the pressure panel and the tank directly, and to the horizontal panel via the cable ties through a fixed guide rings, and a moving device for the ode flushing is accomplished by maneuvering the amount of filler tank, made with internal cable aperture, tightening it above the middle part and is installed on the horizontal panel at the junction of it with the guys carrying the cable management that defines the position in the stream. When this cylinder is mounted on the pressure panel may be made in the form of one or sections of cylinders made and posted in various geometric configurations, and the ballast can be made continuous, sectional, rigid or flexible, with the possibility of copying the bottom of the stream.

The proposed device can be performed in accordance with the order on known and proven technology of tissue structures in the factories of rubber products (for example: OJSC "UZEMIK" (Ufa), JSC "Barnaul plant of rubber technical products").

Washing stream channels produced in the period of low flow in summer.

Before installing the device the stream clear of trees and shrubs and metal objects.

Directly at the place of installation, the device is delivered by road and unloaded by crane. Then laid out on the banks of the stream and collect in accordance with the attached factory Assembly instruction device, mount and secure the power zone. After Assembly of the device made in the field of commissioning.

Simultaneously with the installation of the device at the site of flushing the stream on both sides are two pairs of stationary (e.g., screw) anchors for fastening the movable anchors (e.g. winches).

After you perform the preparatory works to produce movement of the assembled device directly into a watercourse working crews in the composition of 6-8 people (if necessary, may use technical means and boats). After placing the circuit in the direction to produce the fastening bracket control cable with free ends of the cables moving anchors. Maneuvering cylinders, which controls the device, create a mode of filling containers moving along the flushing reservoir. After reaching upstream of the necessary pressure to create a blur alluvial deposition velocities begin the process of flushing channel and clearing the fractions of the sediment with particle diameters, the smaller diameter of the particles projected blind area. To this end movable cloth set by cylinders control in the projected position at which the discharge slit forms a desired flow rate of the flow in the lower reach. In these studies employed two people who exercise, in addition, the motion control of the device, in the second number, in terms of meandering channels.

After flushing a separate section of the channel, or all, the device is removed. To this end, the cylinders is released from the filler by connecting sections of the cylinders with the external environment, the ballast is disconnected from the horizontal panel and move on to the shore, and a panel device line flow in the channel and move on to the shore, where, after drying, is placed in a container and transported to the storage location.

Along the upper edge of the pressure panel 2 is fixed to the float 16, and along the lower cylinder 17, and the cylinder 17 may be made in the form of one or partitions cylinders (17A, 17B, 17c, 17g) (6, 7, 8), hosted and performed in various geometric configurations (e.g., sequentially (6), Phillips (7) or by type dolls with touch in one point (Fig))that will expand the range of maneuvering speeds of erosion, depending on the size of the size of the excavated sediments due to changes in the magnitude the culvert opening of the slit 15.

Culvert slit 15 and the cylinder 17 overlaps the movable panel 3, one edge of which is directly attached to the pressure panel 2 and the cylinder 17, and the other through the connecting loops 8 and a flexible cable connection 18 through the guide rings 12 and the cylinder 11 to the horizontal panel 1. On the movable panel 3 is fixed stabilizing ring 19 connected with cable ties 14 slidable on them.

The upper edge of the pressure panel 2 by means of a connecting hinge 7 and the cable ties 20 is attached to the connecting loops 4 horizontal panels 1, and by means of the coupling loops 4, 7 and cable braces 21 and 22, the entire device is attached to the bearing control cable 23, the ends of which are secured to the shore anchors 24 (figure 2). The device blurs the bottom alluvial deposits 25 up blind area 26, forming alluvial dunworthy clay shaft 27 (Fig 1).

Here are some technical specifications of structural elements of the proposed device.

For the manufacture of panels 1, 2, 3 of the float 16 and the cylinders 9, 11, 17 device is used fabric 8-413 (TU 38 305153-81). Gluing fabric to produce glue SV-1-5B or SV-1-5K (TU 38 305181-82). The firmware of the joints are filled with threads L (Tuna 41-83) or threads ZK (OST 17-330-84) in four lines. Seams sealed hermetization tape L-61 (TU 38-305184-79). Not sealed with seam tape the glue-sealant 8-B or 8-K (TU 38 305253-83).

Cable connection 14, 18, 20 and tether ropes 21, 22 are made of rope with a diameter of 5.2 mm double strand type TC with the calculation of the bursting force of the rope on the whole 20900 N (2132,6 kgf) (GOST 3067-88).

Suspension cable management 23 take a diameter of not less than 25 mm for devices with a width up to 30 m and perceived pressure to 3.5 m is made as a double rope strand type TLC-0 with the calculated breaking force of the rope as a whole - 358500 N (36581,6 kgf) (GOST 3079-80).

Guides and stabilizing ring 12, 19 is made of a rod of circular cross section with diameter 6 mm, made of carbon steel hot rolled ordinary (GOST 380-71) group And mark 3. Inner diameter (dNUMBER) directing and stabilizing rings 12, 19 equal to 8 diameters cable ties 14, 18 (dNUMBER=5,2·8=50 mm).

The filling of the cylinders 9, 11 carry water from the wash flow centrifugal pump performance 2-3 l/s (any brand), and emptying by gravity by opening the discharge pipe of the pump to communicate it to the atmosphere.

The filling of the float cylinders 16 and 17 (17A, 17B, 17c, 17g) carry out atmospheric air using a compressor performance 0,002-0,003 m3/c (any brand), emptying reach by connecting the cavities of the float and sections of the cylinders with the external environment.

As coastal anchors m is tenderly to use a winch size LR-10 weight 18,62 kN with a traction force of 98 kN, with a drum diameter of 480 mm and canadaeast 300 m To the winch is not shifted in position, their frames attach the rope to the anchor. Because when the device is the location of the anchors change, then use screw anchors used on the perception of shifting effort to 98,0 kN inclusive.

A joining device for flushing is as follows.

The cylinder 9 (Fig 3) is filled with water to 0.5 of its volume, ensuring that the involvement of a tether aperture 10, the container 11 is filled in the container 17 is free from filler. Such a filling of the cylinders 11 and 17 will cause a shift cable ties 18, and the connecting loops 8 with attached movable panel 3 in the direction of the upstream, while its position is fixed in relation to cable ties 14 stabilizing rings 19. As a result of this discharge gap 15 overlaps a movable panel 3 and the water accumulating in front of the monument, will cause the rise of the float 16 with the upper edge of the pressure panel 2 held cable ties 20 and cable braces 22. Shear load generated by the hydraulic loads acting on the pressure panel 2, via the cable ties 14 are transferred to the horizontal panel 1, and is partially compensated by the friction forces me what do horizontal panel 1 and the bottom of the channel, strengthen stabilizing ballast 13, when this part of the shifting effort is perceived rope braces 21 and 22 and through the base of the control cable 23 is transmitted to shore anchors 24 (2), the position of which determines the position of the device.

To achieve the estimated level in the direction of ∇ UVB (figure 4) cylinder 11 is released from the filler and the tank 17 is filled with a filler. In the result, the movable panel 3 moves to pressure the panel 2 and the drain slot 15 opens, where will direct the flow of water to scour velocities generated by the pressure - N, measured by the height of the upper edge of the pressure of the cloth 2. The flow of water exiting through the discharge slot 15, blurs bottom alluvial deposits 25 and moves them into the lower reach to a distance determined by its carrying capacity.

As ejection fractions of alluvial deposits 25 and forming in line blind area 26 (Fig 1), the device moves downstream, and the tank 9 is filled to its full capacity (figure 5), which causes the rise of cable ties 20 and provides thereby lifting the top edge of the pressure of the cloth 2 with the float 16. Resulting in increased pressure in front of the device, and increase the shifting hydraulic load, perceived them.

Suspension cable management 23 through b the river anchors 24, lengthen, and the horizontal panel 1 under the action of the horizontal component of the hydraulic load moves over the bottom of the channel in the side of the wash area of the riverbed, where available alluvial faction, prone to erosion, and where they have not formed a blind area 26. After which the cylinder 11 is released from the filler and the tank 17 is filled to the calculated value, causing the movable panel 3 is moved on the pressure panel 2 and opens the discharge gap 15, continuing this process of flushing the stream.

At least reduce the efficiency of the leaching regime created by the device, due to the accumulation in front of him superficial masses and forming them in the form of upstream lunoobraznogo ground shaft 27 (Fig 1), the device is suspended and deposited sediments in the places of their location removed from the riverbed mechanical or hydromechanical way adjacent to the banks of the watercourse floodplain needoba (ravines, gullies, waste career etc). The method of removal of stream sediment is determined in each case individually, based on its economic efficiency.

Besides, to build the river water section to the elevation of the highest level, measurements are made, or the flood plan is levelled down to this elevation, and the wetted perimetre and area of the water section at the various river level are identified with analytic calculations. At the same time additionally to building of the river water section down to the elevation of the highest level, a steep slope is selected on the river steep coast or the flood plant terrace, where the highest point is marked on the line of transition to the plain landscape. This highest point is accepted as the reference point of levelling for survey points arranged in the flood land in specific areas of the landscape. Then the flood land is levelled by heights of survey points arrangement relative to the geodesic reference point on the highest elevation of the steep coast. Besides, a zero point of river depth measurements is also included into the measurements. Afterwards, above the river water surface, a total depth is identified to the river bottom from the geodesic reference point on the steep coast by summation of the river water section depth to the height from the zero point of the river depth measurements to the geodesic reference point on the steep coast. The zero common point in the system of coordinates for measurement of distances along the hydrometric section to survey points in the river bottom and flood land is the point of crossing of the horizontal sighting line from the geodesic reference point on the steep coast with the surface of the flood land on the other side of the river opposite to the steep coast. After production of the table data of measurements, the statistic modelling is used to determine laws in change of total depth of the flood land and the river bottom from the horizontal sighting line depending on distances, starting from the point of crossing of the horizontal line with the flood land surface on the other side of the river from the steep coast.

EFFECT: improved accuracy of hydrometric measurements of the river flood land in the hydrometric section, expanded functional capabilities of hydrometric measurements in cross section of both the river bottom with its flood land and terraces, reduced labour intensiveness of calculations of the main hydraulic characteristics on the basis of application of statistical laws of the river flood land and bottom form in each hydrometric section.

FIELD: water construction purification.

SUBSTANCE: invention relates to hydromechanisation namely to technology of purification and restoration of biological ponds of purification plants. Method of purification and restoration of biological ponds of purification plants includes intake of silt sediments with suction dredge from the bottom of multi-sectional pond and their transportation to sedimentation tanks. Pond is divided into two working areas of treatment, the latter is connected by means of additional input collector with sewage-water supplying canal in direction of sewage water flow motion, the former is blanked off, and construction of ground dam in area of purification is carried out as protective means. After that step-by-step purification of area is performed, for this purpose trench in silt sediments layer is sucked off by suction dredge, after that clarified water is pumped out and discharged into diversion canal. Silt sediments are collected in flowing state and transported either to silt sites or to sedimentation tanks. After that compressed silt sediments are dried by means of active ventilation and removed layer by layer as upper layer dries. After complete removal of silt sediments, base, bed of purified pond section, is restored, and said procedures are step-by-step repeated in successive purification of all sections of first area. Before purification of second working area round dam is erected again in last section of first working area of treatment, separating it from second working area, which is blanked off. First working area is joined to additional output collector with branch duct and opened, after which purification and restoration of sections of second working area are carried out. After finishing purification works ground dam, which was re-erected between two working areas, additional input and output collectors are removed, and second working area of pond is opened for functioning.

EFFECT: ensuring possibility of functioning of purification plants biological ponds without stopping them for purification.

FIELD: hydraulic engineering, particularly for cleaning river, channel beds and other structures of sediments.

SUBSTANCE: method for bed cleaning by sequential transversal bulldozers movement involves coarse planning river bed with the use of bulldozer with flat blade; cleaning river bed by moving bulldozers having comb-like blades with different gaps between knives thereof and forming afflux dams along river banks, wherein river bed cleaning is initially carried out by bulldozers having greater gaps between knives of comb-like blades and then by bulldozers having lesser ones. Dam bodies are formed by sequential moving bulldozers with comb-like blades so that upstream dam face comprises coarse fractions, dam top and downstream face thereof has fine fractions. After that silt free from coarse fractions are moved by bulldozers with flat blades to river bed axis to provide following carry-over thereof by high flood.

EFFECT: increased efficiency and economy.
