Technical Field

[0001] This utility model relates to the field of underground drainage equipment technology, and in particular to a pressure-limiting and anti-buoyancy drainage structure for underground engineering. Background Technology

[0002] Underground engineering projects include subway tunnels, underground parking garages, underground shopping malls, underground pipelines, etc. These projects often require drainage of groundwater, and at the same time, the buoyancy effect of groundwater on the structure must be considered. The buoyancy effect may damage the underground engineering project and affect its stability during use. Traditional underground drainage structures are not convenient for depressurization and anti-buoyancy during drainage.

[0003] Therefore, it is necessary to design a pressure-limiting and anti-buoyancy drainage structure for underground engineering. Utility Model Content

[0004] The purpose of this invention is to provide a pressure-limiting and anti-buoyancy drainage structure for underground engineering, in order to solve the defects of existing underground drainage structures that are inconvenient to depressurize and resist buoyancy during drainage.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a pressure-limiting and anti-buoyancy drainage structure for underground engineering, including drainage components;

[0006] The drainage assembly includes a drainage base, a drainage channel, and a guide plate. The drainage base has a drainage channel inside, and guide plates are fixed on the outer walls of both sides of the top of the drainage base.

[0007] The top of the drainage trough is provided with a pressure limiting component, which includes a pressure limiting seat, a water storage chamber, a protective structure, a pressure relief structure, a top plate, a drain pipe, and a water pump. The pressure limiting seat is located on the top of the drainage trough, and a water storage chamber is provided inside the pressure limiting seat. A top plate is fixed to the top of the water storage chamber, a water pump is installed on one side of the bottom of the water storage chamber, a drain pipe is provided on one side of the water pump, and a protective structure is provided on the top of the top plate.

[0008] The top of the water storage chamber is provided with a pressure relief structure, which includes a pressure relief box, a pressure relief cavity, a mounting plate, a drain hole, and a connecting pipe. The pressure relief box is located at the top of the water storage chamber. The mounting plate is installed on the outside of the pressure relief box. The pressure relief cavity is opened inside the pressure relief box. Drain holes are evenly opened inside the pressure relief box at the bottom of the pressure relief cavity. A connecting pipe is provided inside the pressure relief box.

[0009] Preferably, the protective structure includes a protective cover plate, filter holes, limiting holes, and limiting blocks. The protective cover plate is disposed on the top of the top plate, and filter holes are evenly distributed inside the protective cover plate. The limiting holes are evenly distributed on the top of the top plate, and limiting blocks are disposed inside each limiting hole.

[0010] Preferably, the top of the protective cover and the top of the top plate are located on the same horizontal plane, and the filter holes are evenly distributed inside the protective cover.

[0011] Preferably, the limiting hole and the top plate form an interference fit structure through a limiting block, and the top end of the limiting block and the bottom end of the protective cover are fixedly connected.

[0012] Preferably, the two ends of the mounting plate are fixedly connected to the inner wall of the pressure relief seat, and the drain holes are evenly distributed inside the pressure relief box.

[0013] Preferably, the top end of the connecting pipe extends to the top of the pressure relief chamber, and the bottom end of the connecting pipe extends to the bottom of the drainage trough.

[0014] Preferably, the bottom end of the drain pipe is fixedly connected to the output end of the water pump, and the top end of the drain pipe extends to the top of the drain trough.

[0015] The present invention provides a pressure-limiting and anti-buoyancy drainage structure for underground engineering, the advantages of which are:

[0016] By incorporating a pressure relief structure, as water flows into the drainage trough, the water level gradually rises and the water pressure gradually increases. Subsequently, under the action of this pressure, the water flows through the connecting pipe into the pressure relief chamber and then through the drain hole into the water storage chamber. The water is then pumped back into the drainage trough via a water pump and drain pipe. This process can relieve the pressure of the water flow and prevent the water from generating excessive buoyancy due to the rising water level during flow, which could damage the drainage structure. This enables the device to have pressure limiting and anti-buoyancy functions, thereby improving the service life of the pressure limiting and anti-buoyancy drainage structure.

[0017] With the protective structure, the filter holes can protect and filter the water storage chamber, preventing impurities from falling into the interior of the water storage chamber. At the same time, it makes it easier for staff to inspect and maintain the pressure relief structure. This realizes that the device has the functions of protection and filtration, and improves the convenience of using the pressure limiting and anti-buoyancy drainage structure.

The protective cover plate 2031 is located on the top of the top plate 205. The protective cover plate 2031 has filter holes 2032 evenly distributed inside. The limiting holes 2033 are evenly distributed on the top of the top plate 205. The limiting holes 2033 are all provided with limiting blocks 2034 inside. The top of the protective cover plate 2031 and the top of the top plate 205 are on the same horizontal plane. The filter holes 2032 are evenly distributed inside the protective cover plate 2031.

[0028] Reference Figures 2-5 A pressure relief structure 204 is provided at the top of the water storage cavity 202. The pressure relief structure 204 includes a pressure relief box 2041, a pressure relief cavity 2042, a mounting plate 2043, a drain hole 2044, and a connecting pipe 2045.
