Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of road drainage engineering, in particular to a road surface drainage ditch cover plate for municipal engineering and a laying method thereof. BACKGROUND

[0002] Road drainage has always been an important part of municipal road construction. With the increasing speed of urban development, the advantages and disadvantages of municipal roads are constantly amplified. One of the factors to consider the quality of road construction is the road drainage structure. Through the road drainage structure, the accumulated water on the road can be drained away from the road surface during rain, reducing the impact of road waterlogging on pedestrians and vehicles. The existing drainage mechanism is to build drainage ditches on both sides of the roadbed, and then set cover plates on the drainage ditches. Subsequently, water enters the drainage ditch through the cover plate opening for drainage.

[0003] The existing drainage ditch has multiple drainage grooves on the top of the drainage plate when used for drainage. Water enters the drainage ditch through the drainage grooves. However, the drainage grooves are in an open state for a long time. During the non-drainage process, some debris will enter the drainage groove and block the drainage groove. At the same time, some debris will also enter the drainage ditch along the drainage groove and cause the drainage ditch to be blocked, thereby causing the road drainage mechanism to be unable to drain water, leading to road waterlogging. SUMMARY

[0004] The purpose of the present application is to provide a road surface drainage ditch cover plate for municipal engineering and a laying method thereof. The cover plate can be in a closed state when not draining water. When there is water on the road surface, the drainage groove automatically opens for drainage. This prevents debris from blocking the drainage groove during non-drainage or excessive debris from entering the drainage ditch and causing the drainage ditch to be blocked. This improves the smoothness of the drainage ditch drainage. At the same time, the drainage groove can be automatically cleaned during drainage to prevent the drainage groove from being blocked, improving the efficiency of the cover plate drainage. At the same time, it is convenient for portable and stable installation of the cover plate, and convenient for laying personnel to lay and other advantages.

Step four, in the cement groove builds the fixed strip, then the cover plate main body is put into the drainage ditch, then presses the top of the cover plate main body, makes the fixed mechanism on the cover plate main body fixed in the fixed strip and is fixed, then installs the next cover plate main body, inserts the plug on the next cover plate main body into the connecting slot on the last cover plate main body, then installs the top of the cover plate main body and is fixed through the fixed mechanism, realizes the paving of the cover plate in turn reciprocating.
