Cerebrosidase channel

 

(57) Abstract:

The invention relates to hydraulic construction and can be used as cerebrosidase channel. Cerebrosidase channel includes a tray polygonal cross-section with symmetrical slopes - two side and two bottom. What's new is that the tray fortified combined cladding consisting of a flexible reinforced concrete grillage and rubble fastening with thick rubble masonry not less than 45 cm, with reinforced concrete pile caps are located across the cross section of the tray along the lines of the side and bottom of slopes at a distance from each other and consist of a series of concrete prismatic blocks, connected by an anchor to the base, connected by cables and protruding above the level of the rubble mounting and bottom slopes of 30-40 cm, while the protruding portion of concrete blocks with the pressure side is designed with a slope faces and oriented opposite the direction of the debris flow at an angle of 30-40o. The technical result of the invention is to increase the efficiency of cerebrosidase channel and reduction of material costs on its mount. 2 C.p. f-crystals, 5 Il.

The invention relates to hydraulic is the first device [1], containing tray installed in the debris flow channel, the bottom of which is made of loosely laid on its side beams strung with them cylindrical elements. Thus, the bottom is a flexible rough surface with an opposite slope, which provides damping of the energy flow. The disadvantage of this technical solution is that such proteosolve device is very difficult to build in wide and long trays, to ensure the reliability and sustainability of its work requires significant material costs, that is, it is quite difficult and unreliable mechanism.

Relative to the closest technical solution is a hydraulic channel [2] , containing the tray polygonal cross-section with symmetrical slopes - two side with the ground lines of 0.4-1.5 and two bottom with ground lines of 2.5 to 6.0. However, to use this solution as cerebrosidase tray is impossible without powerful and reliable fastening of facing of its cross section in the case where the route of the canal passes through earth ground. And the device is a high-strength solid concrete mounting slopes of the channel will be very costly. In addition, hard geleit without flexible joints. And this in turn leads to greater appreciation of the construction of the canal.

The purpose of the invention is the efficiency cerebrosidase channel and reduction of material costs on its mount.

This objective is achieved in that the polygon slopes of the channel are strengthened combined cladding consisting of a flexible concrete wasterock, rubble or Arnautovic clutches. Concrete gratings are located across the cross section of the tray along the lines of the side and bottom of slopes at a certain distance from each other. The grids consist of a series of prismatic concrete blocks, anchored to the base and connected by cables. Lateral slopes between reinforced concrete Foundation reinforced rubble or arnautovi masonry. The main load of debris flow will perceive reinforced concrete pile caps, they are arranged so that their upper faces were 30-40 cm above the level of the side mounts and bottom of slopes. While riding the verge of concrete blocks is oriented against the direction of debris flow with an angle of inclination of the face to the line direction of the bottom of the channel 30 to 40o.

In Fig. 1. pictured Popper is a; in Fig. 3 is a cross section of the channel 2-2 on rubble masonry fastening; Fig.4 is a longitudinal section 3-3 along the axis of the channel of Fig.5 is a longitudinal section 4-4 on the fastening side of the slope.

Cerebrosidase channel includes a tray polygonal cross-section with symmetrical slopes - two side 1 and two bottom 2, reinforced combined cladding. Completed lining of flexible concrete wasterock 3 and rubble fasteners 4. Grids 3 are located across the channel cross section at a certain distance from each other, consist of a series of prismatic concrete blocks 5, which are attached to the base anchors 6 and are connected by cables 7. Concrete blocks 5 grids 3 are 30-40 cm above the rubble of the mounting 4 and the bottom slopes 2. The protruding portion 8 concrete blocks 5 with the pressure side is designed with a slope face 9 against the direction of debris flow at an angle of 30-40o.

Cerebrosidase channel is constructed as follows:

In debris flow channel is developed channel polygonal cross-section with symmetrical slopes 1 and 2. In the necessary places are arranged trenches reinforced concrete grillage 3, installed and then embedded anchor 6, built Yeti 8 and 9 concrete blocks 5 are made of high-strength abrasion-resistant concrete. Then mount of rubble 4, using the stones of medium size 30-50 see When laying the stones are reinforced and strengthened reinforcing wire mesh. Rubble masonry 4 can be performed with the addition of cement or concrete. The degree of reinforcement of masonry or device rubble masonry and its thickness is determined depending on the existing load of debris flow. Flexibility fastenings shall be provided with deformed joints. In any case, the thickness of rubble masonry shall be not less than 45 cm

The width and the thickness of the reinforced concrete grillage 3, number of anchors 6 are determined based on the possible maximum hydrodynamic effects of debris flow. Bottom slopes between 2 concrete pile caps 3 are not strengthened.

Cerebrosidase channel works as follows.

When passing sat on the channel due to the polygonal shape of its cross section maximum load per unit of mudflow focus on the center of the channel along the triangular base. The greatest hydrodynamic and abrasive sat perceive the protruding parts 8 and 9 jelezobetonnije 3, pressing them to the bottom. In this regard, and due to the flexibility of the design of reinforced concrete blocks 5, located at the base of the bottom slopes 2, under the influence of the stream sat a small move in the horizontal direction, there is a tension cables 7 and anchors 6. And the blocks 5, located on the side slopes of 1 acting on them load pass side mounts 4 and receive a relatively smaller displacement. Quarry mount because of the flexibility of their design and location them on the side slopes of 1 between reinforced concrete grillage 3 below perceive relatively smaller load and work primarily in compression. Thus, the excess energy of the debris flow is scattered across the entire cross-section with uniform damping of its length. The channel is relatively evenly and freely provides pass debris flow without appreciable deformation in the lining.

Strong deformations will be unfortified part of the bottom slopes 2 between the gratings 3, in the beginning of may erode the riverbed below the line of the bottom depth of 1-1 .5 m between the gratings along the bottom of experiencing stagnant zones, with a sharp drop of the longitudinal velocity. As a result, the erosion is stopped and the parts of the bottom of the channel between the gratings 3 back begin to blur, thus, these sites periodically will then be washed, saratica. And these deformations are not dangerous for gratings 3 and fixtures 4 side slopes 1. Because of the triangular shape of the base of channel erosion occurs at the center of the channel between grids 3. Themselves firmly reinforced concrete grillage 3 does not allow to extend the erosion of the riverbed and will always retain the shape of its cross section. For this purpose, the distance between the gratings 3 should be no more sustainable in channel width, LB.

For conditions of mountain rivers is recommended to take L=20-30 m This cerebrosidase channel is designed to safely pass sat on the mountain and foothill urban river sections, where possible gatherings debris flows with costs Q100 m3/s

Cerebrosidase channel combined lining ensures reliable protection of the riparian zones of rivers, where it can be located settlements, industrial and agricultural land, roads and other, from erosion and flooding, mudflows.
