Abstract
Description
Technical Field
[0001] This utility model relates to the field of road drainage technology, and in particular to a municipal road and bridge drainage device. Background Technology
[0002] As we all know, when water accumulates on the surface of highway bridges during rainy days, the tires of vehicles traveling at high speeds can become slippery and lose control due to the accumulated water, leading to serious traffic accidents such as vehicle skidding or rollover. Therefore, it is necessary to install drainage facilities on the surface of highway bridges to quickly remove water from the bridge. The drainage system should be able to filter the water, and with long-term use, the filter should be easy to clean and replace. Existing drainage facilities are prone to clogging, and when rainfall is heavy, they cannot drain rainwater quickly, affecting road traffic safety. Utility Model Content

A drainage grate is provided on the upper side of the drainage ditch. Multiple sets of drainage ditches are evenly distributed along the edge of the road surface. Drainage pipes are connected between the multiple sets of drainage ditches. An overflow pipe is provided on one side of the drainage ditch, and a bypass pipe is connected to the bottom of the overflow pipe. A filter device is provided on the lower side of the drainage grate. The filter device includes a flow plate, a filter screen, and an overflow plate. The flow plate is inclinedly arranged on the upper part of the drainage ditch, and a raised strip is provided on the upper side of the flow plate. The overflow plate is arranged in a U-shape and is located on the upper side of the flow plate. The filter screen is located on the upper side of the overflow plate.
[0005] Preferably, one side of the flow plate is detachably hinged to the drainage grate, and the inner wall of the drainage channel is provided with a positioning block adapted to the flow plate.
[0006] Preferably, the overflow plate is inclined at its upper edge, and the drain grate is evenly provided with mesh holes; the filter screen is provided along the upper edge of the overflow plate, and the filter screen is provided with square holes corresponding to the mesh holes.
[0007] Preferably, the convex strips are provided in multiple sets and are evenly arranged on the upper surface of the flow plate. The convex strips are parallel to the hinge axis of the flow plate, and a sedimentation tank is formed on the higher side of the flow plate where the convex strips are located.
[0008] Preferably, a drain pipe is provided on one side of the overflow pipe, one end of the drain pipe penetrates the side wall of the drainage trough and extends to the lower side of the flow plate, a filter cover is provided at the end of the drain pipe, and the bottom of the drain pipe is higher than the bottom of the drainage pipe.
[0009] Preferably, the overflow pipe is vertically arranged and corresponds one-to-one with the drainage trough. Multiple sets of overflow pipes are connected by bypass pipes, and the bypass pipes are connected to a water storage tank. The top of the overflow pipe is provided with a sealing cap, and a water level gauge and a water pump are provided inside the overflow pipe.
[0010] The beneficial effects of this utility model are as follows: Compared with the prior art, this utility model has a filter device under the drainage grate. The silt in the sewage is collected by the flow plate and overflow plate. When the rainfall is large, the sewage overflows directly, avoiding the filtration device from being blocked and affecting the drainage, thus ensuring the reliability of drainage. At the same time, the overflow pipe and bypass pipe are set to increase the drainage volume in the rainwater collection area, avoid road water accumulation, and ensure road traffic safety.
