Concrete setting pot is set respectively at the mouth of pipe of water pipe and outlet pipe, its feature is：In water inlet pipe with containing bottom horizontal tube turning
Interface is provided with sand-precipitating tube, is equally additionally provided with sand-precipitating tube with outlet pipe turning interface in culvert bottom horizontal tube；Containing bottom horizontal tube
Water inlet end aperture in be provided with grid, grid is formed using reinforcement welding.
The characteristics of the utility model, also resides in：
Described sand-precipitating tube is a cylinder, and cylinder both ends cover welded seal, cylinder stack shell both sides are welded with water respectively
Flat tube coupling and inclined tube section, weld must not leak；Described horizontal tube coupling and inclined tube section forms by plain plate through rolling；Two
Horizontal tube coupling on sand-precipitating tube is connected with containing bottom horizontal tube, and the inclined tube section on two sand-precipitating tubes connects with water inlet pipe, outlet pipe respectively
Connect, specifically connected using loose flange type, be that bolt is arranged in screw after being fitted into gasket seal in bump joint end
Use nut check.
If the lower edge of described horizontal tube coupling and the distance at sand-precipitating tube cylinder bottom are h2, the lower edge and sand setting of described inclined tube section
The distance at cylinder cylinder bottom is h1, then h2 is more than h1.
Described culvert bottom horizontal tube, water inlet pipe, outlet pipe and sand-precipitating tube stack shell uses corrugated steel pipe.
The advantages of the utility model and beneficial effect：
1st, because being respectively equipped with sand-precipitating tube with containing bottom horizontal tube turning interface in water inlet pipe, outlet pipe, containing, bottom is horizontal
Grid is provided with the water inlet end aperture of pipe, so can prevent silt particle and debris from entering culvert bottom horizontal tube and causing culvert pipe to block, i.e.,
Make also collect in water outlet sand-precipitating tube into the silt particle of horizontal pipeline section on a small quantity；During regular desilting, it is only necessary to remove sand-precipitating tube
The silt particle debris of bottom deposit, contain the progress desilting of bottom horizontal tube without entering.
2nd, sand-precipitating tube can prefabrication, with its substitute turning elbow, cost can be saved and facilitate site operation again.
