The invention relates to the management and regulation, namely to devices for automatic regulation of the groundwater level, as well as regulation in rice fields, open channels and water drainage wells-watering systems when the subsoil moisture.

A well-known regulator of the groundwater level, installed in the observation well and containing a Poppet valve with a float actuator, the housing of which is mounted on the cap drains, the camera installed in her float and level sensor ground water in the form of tubular filter (inventor's certificate SU # 763519, CL E02B 11/00, 1980).

The known device is difficult to manufacture, in the process of operation due to sedimentation and sogrevaniya gauge tubular filter is not provided with sufficient accuracy maintaining predetermined pressures, wherein the tubular filter is located at 3-5 m above the well in the characteristic point depression curve, ie may not work in all range of regulation of drainage water depending on fluctuations in water level in the drainage system.

Furthermore, the design of the movable cylinder Poppet valve interconnected to move relative to each other in welded housing complex in operation and leads to significant efforts to overcome the guide�staticheskogo pressure in welded casing, acting on the entire area on the Poppet shutter when it is opened. These efforts reduce the reliability of operation of the device, and hence the reliability of its operation. It is also unreliable due to friction of the rack on the vertical rod and the lack of a control system for a full trim lever of the device in two opposite directions, causing the randomness of the selection of its provisions.

The closest of the analogues adopted for the prototype, is a device for controlling the level of groundwater containing a well with in it the cap drains are fitted with a valve body, the float actuator mounted in the chamber, which communicates with the well and the pipeline is connected with the drain (inventor's certificate SU # 1013560, CL E02B 11/00, 1983).

The disadvantage of this device is that it cannot control the downstream, and therefore cannot be used in a cascade of such structures along the length of the manifold, while in the process of operation does not seem accurate and flexible regulation of the groundwater level due to constant manual opening or closing of the valve in the side wall of the chamber, which adversely affects the yield of crops. In addition, the lever arm and the throttle is not�orestano in the pit complicates the design and increases the error in the stabilization of a given flow, and having to set up the float with the work of spillway gate in each specific case of application in real conditions. It is also unreliable due to friction of the piston in the slide and the lack of a control system for a full trim actuator when the shutter is closed, it is difficult to operate.

The proposed device aims to eliminate these drawbacks by design, which allows to reduce the amount of hydrostatic pressure during opening and closing of the self-regulating mechanism in the form of a diaphragm rod connected through dvuhplechem of the lever with the piston and the valve, the latter placed in the additional chamber communicated with the cavity of the reservoir, and through the design overall, which increases the efficiency of the device reliability and quality control of water in the drainage system.

The objective of this solution is to increase the efficiency of the device by permanent use of drains along its entire length.

The technical result is achieved in that the device for regulating the level of groundwater, including the drain well with in it the cap drains, shut-off body, the actuator and the chamber communicating with the cavity of the reservoir, characterized in that it is provided mounted self-regulating mechanism controller� in the well and consists of a regulator of pressure made in the form of a membrane, is provided below the protective net limiter type of displacement of the membrane, anchored to the membrane at the top of the housing, nomembrany cavity which is communicated with the atmosphere and connected with the valve stem through dvuhplechem lever with the exhaust valve closing off the hole on the bottom of the camera, and the stem of the exhaust valve is provided with a piston for supplying water into the cavity of the manifold, while the exhaust valve is placed in the secondary chamber, in the side wall of which is a calibrated orifice associated with the well, in addition, the bottom of the chamber has an inlet valve associated with the float, placed with the possibility of adjunction to the last tabs-limiters.

In addition, with valve stem self-regulating mechanism is provided with a spring supporting the valve attached to the membrane.

In this membrane and the piston have different effective area, which are connected through dvuhplechem lever.

The drawing schematically shows a device for regulating the level of groundwater.

A device for controlling the level of groundwater includes the inlet drains 1, cumulative the well 2 which has a self-regulating mechanism 3. Self-regulating mechanism 3 consists of a housing 4 which is attached to tubular drena 1 and the partition wall 5 separating the well 2 on the upper 6 and lower part 7 through the outlet openings 8, in addition, the upper part 6 of the well 2 is additionally covered with a plate 9, which is fixed to the chamber 10. Setting self-regulating mechanism 3 includes a pipe 11 for connecting nedobrotnogo space 12 with the atmosphere of the membrane 13, the valve 14, the compressed spring 15 and the actuator rod 16 dvuhplechem of the lever 17, the rod 18, the piston 19, the exhaust valve 20, overlapping the hole 21 in the chamber 10, a protective limiter 22 mesh type (dome shape) the movement of the membrane 13, and a protective limiter 22 is fixed to the side of the bottom of the well 2.

The chamber 22 is communicated with the well 2 through the inlet 23, the valves 24 associated with the float 25 that is in contact with the tabs-limiters 26. The chamber 10 communicates with the cavity of the manifold 27 through the secondary camera 28, in which the exhaust valve 20, the side wall of the chamber 28 through a calibrated opening 29 communicates with the upper part 6 of the well 2.

A device for controlling the level of groundwater is as follows.

Entering drains 1 water flowing down the slope, falls into the collecting well 2. Cumulative well takes water up until the water in it does not rise to the level of the float 25 and the filling chamber 10, and therefore, as long as the water in the chamber rises to the piston 19. The pressure in the well 2, �ness in the range differential, the deformation of the membrane 13 of changing its form, i.e. the wall of the cave in which, by moving up the rod 16, the compression of the springs 15, and through dvuhplechem the lever 17, the rod 18 moves the piston 19 in the chamber 10. Moving down, the piston 19 pumps the water from the chamber 10 through the opened exhaust valve 20 in chamber 28, which is connected with the cavity of the reservoir 27. Simultaneously, water from the upper part 6 of the well 2 flows through a calibrated opening 29 in the side wall of the chamber 28.

When the membrane 13 of the top position will stop the compression of the spring 15, and therefore, will stop further movement of the piston 19. The valve 24 is closed. The pressure of water in the well 2 decreases in the interval drain from the chamber 10 through the exhaust hole 21 of the valve 20 and decreases. The membrane 13 under the influence of spring 15 will move in the direction of the protective limiter 26 and the stem 18 to move the piston 16 and the valve 20. The valve 20 will block the outlet opening 21. Water from the inlet drains 1 again starts to flow into the well 2 and to increase the pressure of water in the well 2. From this point the water flow into the reservoir 27 will begin to repeat analogous to the foregoing.

When exceeding the level of water in the well 2 is increasing piezometric head in the drains-humidifiers, resulting in higher groundwater levels. Thus, due to the presence of Simoreg�stimulating mechanism and in fluid communication with the chamber 22 with the piston 19, and shut-off valve 25 is a pressure regulator, limited piezometric head in the drains-humidifiers (not shown for simplicity) by maintaining a predetermined level in the well 2 and corresponding groundwater levels. Upon reaching groundwater predetermined level, this level will be maintained until the soil moisture reaches a predetermined capillary recharge, i.e. when the humidity goes down.

The water level in podobrannoj cavity from the side of the protective limiter 22 is increased in proportion to the level change in the regulated facility and causes the opening of valve 20. The size of the membrane 13 is selected such that the magnitude of the pressure of the water in the well 2 provided the opening of the valve 20 by the movement of the piston 19 on the rod 18 downward, resulting in additional water enters the chamber 28 is connected with the cavity of the reservoir 27. The well 2 can be gradually unloaded to a certain level through the outlet calibrated orifice 29 of the side wall of the additional chamber 28, thereby in the well can accumulate a predetermined flow of water to the level of the float 25, and, ultimately, the amount of water in the well 2 also limits the maintenance of piezometric pressure in the drains-humidifiers.

Thus, the installation of self-regulating mechanism in the well, the protection of� membrane damage and other elements of the closed mechanism, being in constant contact with the atmosphere, can completely eliminate the disadvantages of the known regulators of groundwater level, and thereby to increase the efficiency of the device.

FIELD: agriculture.

SUBSTANCE: method comprises twisting the device for drain formation in the ground or soil to the desired depth. The device consists of dual hollow tubes. The outer tube has uniformly spaced protrusions of constant rectangular section rigidly fixed on the lateral cylindrical surface along the helical line with a constant pitch. After reaching the desired depth by the device, the inner tube together with the cohesive soil is removed from the outer tube to form a hollow space. The soil is removed from the inner tube. Then the inner tube is wrapped with anti-suffusion material and placed back into the hollow space of the outer tube. Then filter material is poured. The dual outer and inner tubes as filled with the filter material are twisted using a handle.

EFFECT: increased efficiency and productivity in the construction of vertical drains in cohesive soils.

FIELD: construction.

SUBSTANCE: method for horizontal draining of waterlogged structures on pile foundations relates to construction, namely to the construction of drainage systems for the protection of structures on pile foundations against ground water logging. As per the proposed method, dewatering of a waterlogged object is achieved due to the fact that from one radial drain well developed along the outer wall outside the structure normally to rows of the load-carrying piles and equipped with a filter there passed are additional side drain wells between the rows of piles. Drilling of additional shafts is performed by means of a downhole motor and diverting devices out of the above said radial well. The steadiness of walls of the additional wells at drilling is provided by the application of hydrolysed polyacrylonitrile or other self-decomposed drill fluids. After driving of the side additional shafts is completed, the drill tool is disconnected and used for the shutoff of the well bottom, and the motor together with drill pipes is removed through a filter pipe that was drawn by means of the downhole motor.

EFFECT: proposed drainage system allows solving a problem of protection against waterlogging of structures on pile foundations.

FIELD: hydraulic structures, particularly to consolidate slopes or inclinations to be eroded by ground waters.

SUBSTANCE: method for slope protection against landslide by diverting ground water with the use of drainage mine tunnel, through filters and upward dewatering wells involves excavating mine tunnel beginning from lower point of original ground under water-bearing horizons with tunnel elevation for water gravity flow, wherein mine tunnel extends parallel to direction of water flow from water-bearing horizons; excavating mine tunnel in different directions perpendicular to above flow direction; performing drilling vertical venting wells at tunnel ends beginning from original ground; drilling upward dewatering wells in water-bearing horizons; drilling vertical wells from original ground used as through filters crossing all water-bearing horizons; connecting thereof with cross-headings excavated from mine tunnel; installing valves at through filter ends; providing filtering members at place of intersection between upward dewatering wells and vertical wells with water-bearing horizons; forming water removal channel in mine tunnel and connecting thereof with original ground; drilling hydraulic observing wells beginning from original ground along line of through filters to control water level in water-bearing horizons.

EFFECT: increased reliability; possibility of diverting 85-90% of water contained in water-bearing horizons.
