Technical Field

[0001] The utility model relates to the technical field of tunnel water accumulation prevention, in particular to a tunnel water accumulation prevention structure. Background Art

[0002] The drainage system of a tunnel is an important part of the tunnel construction, normal use and safe operation. Among them, the important component of the drainage system is the components of the anti-waterlogging structure. Therefore, anti-waterlogging is directly related to the quality of the underpass construction and whether it can perform its functions.

[0003] At present, cast-in-place concrete anti-water accumulation structures are commonly used in tunnels. The anti-water accumulation and drainage function of the tunnels is mainly to drain the water downward through the drainage troughs through the natural infiltration of the water and the effect of gravity. However, the drainage speed is slow. In periods of heavy rainfall or rainstorms, the speed of draining the water from the drainage troughs is much slower than the speed of precipitation, which leads to serious water accumulation in the tunnels below, posing a high safety hazard. Therefore, a tunnel anti-water accumulation structure is urgently needed to solve the above problem. Utility Model Content

[0014] The filter screen is arranged in the middle of the drainage groove.

[0015] As a further solution of the utility model: a water pumping pipe is arranged inside the drainage trough, and a fixing seat is fixedly connected to the circumferential outer wall of the water pumping pipe.

[0016] As a further solution of the utility model: the fixing seat is fixedly connected to the bottom outer wall of the supporting plate.

[0017] As a further solution of the utility model: a water pump is fixedly connected to one side of the water pump pipe, an end of the water pump away from the water pump pipe is connected to a connecting pipe, and a butt pipe is fixedly connected to the circumferential outer wall of the connecting pipe.

[0018] As a further solution of the utility model: a clamping hole is provided at the top of the installation groove, and a clamping column is fixedly connected to the bottom of the grille cover plate, and the clamping column matches the clamping hole.

[0020] At the same time, by setting a filter screen in the middle of the drain trough, it can play a certain role in filtering impurities and avoid blockage inside the drain pipe during long-term work. At the same time, there is a certain vertical distance between the pumping pipe and the filter screen, so the stability of the pumping pipe during the pumping process in rainy weather can be guaranteed, and impurities deposited on the filter screen will not be drawn into the pumping pipe.
