A municipal drainage ditch and its construction method

Abstract

A municipal drainage ditch and a construction method thereof belong to the field of municipal drainage. The interior of the trench body is laid with a fine sand layer, a crushed stone layer, and a cement cushion from bottom to top; the bottom plate II is fixed at the bottom of the shaft II, and the lower end of the bottom plate II is provided with a gravel layer and a fine sand layer; The masonry layer is fixedly connected to the annular backing plate, and the masonry layer is attached to the inner wall of the shaft II; the cement layer is arranged on the inner wall of the masonry layer; the manhole cover II is movably connected to the upper end of the masonry layer; The pipe is laid on the ground, and one end of the pipe communicates with the trench body, the pipe passes through the shaft II, and the middle part of the pipe communicates with the shaft II. The present invention is provided with shaft II, and the lower end of the annular backing plate of shaft II is directly connected with the soil, and after rainwater enters shaft II, it can directly infiltrate into the deep soil, increasing the flood discharge capacity of the drainage ditch; , the household garbage can be directly flowed into the shaft I through the pipe, so as to reduce the random drifting of the household garbage with the rainwater.

Description

technical field [0001] The invention relates to a municipal drainage ditch and a construction method thereof, belonging to the field of municipal drainage. Background technique [0002] In order to prevent too much water accumulation in the city from affecting pedestrians and vehicles, cities set up drainage ditches. The current drainage ditch can only realize the drainage function, but the drainage capacity of the current drainage ditch is limited. When the rainfall is large, there will still be too much water on the road, which will affect the travel of pedestrians and vehicles; The domestic garbage in the area is easy to float over the drains at will, affecting the urban environment, and it is more troublesome for cleaners to clean up. Contents of the invention [0003] The object of the present invention is to provide a municipal drainage ditch and its construction method to solve the above-mentioned problems in the background technology. [0004] The present inventi...
