Abstract

Usage: in the construction of drainage of underground hydraulic pipes. SUMMARY OF THE INVENTION: before installing the steel cladding 6 in the design position, outlet openings 9 are made in its lower corners, which are closed with temporary plugs, the drainage manifolds 5 are mounted in the form of grooved steel elements welded with longitudinal edges to the outer surface of the cladding 6 across the water conduit, and after installation facing 6 in the design position and concreting in it, opposite the collectors 5, holes 11 are made, the conductors are mounted in them, and through them water-wadded wells 2, then the hole and choke 11, then removed and the plugs are welded and wall 6 and bottom wall inside the steel expandable conduit to the outlet conduit to form the strip 7 in its corners water boiling cavities 8, plugged with horse side. 2 s.p. f-ly, t ill.

SUBSTANCE: invention relates to drainage devices of underground hydraulic structures, in particular to drainage chambers of underground water conduits equipped with steel claddings.

The purpose of the invention is to simplify the design, as well as technology and improve the safety of construction in a flat bottom conduit.

In FIG. 1 shows a General view of the drainage in the transverse section of the conduit, in FIG. 2 is a section AA in FIG. 1, in FIG. 3 - node I, figure 4 - node II.

The proposed drainage includes 1 drainage wells drilled in the ground 2, located in the concrete 3 of the lining of the water conduit, k drainage collectors 5, which are formed by grooved steel elements welded with longitudinal edges to the outer surface of the steel lining 6 across the water conduit “Outlets of drainage water are made in the form of steel strips 7, welded with longitudinal edges to the steel lining 6 of the bottom and walls inside the conduit with the formation in the corners of the conduit 4 spawning cavities 8 and holes 9 in the steel lining 6 in the conduits opposite the collectors 5 and the water supply cavities 8. On the upper side, the water supply cavities 8 are plugged, and the steel strips 7 in the initial section 10 are made expanding towards the outlet part

water conduit b. 1

The proposed drainage is carried out as follows.

In the manufacture of steel claddings 6, grooved elements (drainage collectors) 5 are welded on their rear side according to the design, holes 9 are made and the ends of the grooved elements and holes 9 are sealed to prevent cement milk from getting into the cavity of the drainage collectors 5 in the production of concrete and cement discount during the construction of the water conduit, as well as sludge during drilling of drainage wells 2. Install mounting grades of steel cladding 6 and concrete lining of the water conduit 4. Carry out cementation work. Then, opposite the drainage wells 2 are made in steel

to the lining 6 of the hole 11, conductors are inserted into them (not shown in the drawings) and grabbed to the lining 6, and after the completion of the drilling of the next well 2, the grooved elements 5 and the water-conducting cavities 8 (drainage outlets) are washed. After the completion of the drilling of all wells 2, the holes 11 in the steel lining 6 are hermetically sealed with plugs. Then open the holes 9 and weld the steel strip 7.
