A civil air defense underground drainage system

Abstract

The present invention relates to the technical field of civil air defense engineering, more specifically, it relates to an underground drainage system for civil air defense. Sewage pump, the sewage pump is connected with a drainage pipe extending to the top of the sealing plate; there are several large-diameter drainage holes and small-diameter water inlet holes on the upper circumference of the sealing plate, and an adjustment plate is connected to the sump, which corresponds to the level It is located under the sealing plate, and the adjusting plate is provided with a permeable hole corresponding to the drainage hole. The installation frame is provided with a driving mechanism for driving the adjusting plate to rotate. Closures for securing filter assemblies. The system has the advantages of speeding up the sewage entering the sump when there is too much water in the local area, and the drainage holes are not easy to block, which can make the malodorous gas in the sump difficult to discharge and spread to the civil air defense basement, and protect the surrounding environment of the civil air defense basement.

Description

technical field [0001] The invention relates to the technical field of civil air defense engineering, more specifically, it relates to an underground drainage system for civil air defense. Background technique [0002] In civil buildings, it is often encountered that underground garages and civil air defenses are combined in peacetime and wartime structural design, that is, the basement floor is used as a garage in normal times, and the second basement floor is used as civil air defense in wartime. The design of water supply and drainage in the second underground floor is very important, and sump pits are usually set in the second underground floor. [0003] The drainage structure of the civil air defense basement in the prior art often sets a sealing plate on the top of the sump, and several drainage holes are opened on the sealing plate, and a sewage pump is arranged at the bottom of the sump, and the sewage pump is connected to a channel extending to the outside of the su...

AI Technical Summary

Problems solved by technology

[0003] The drainage structure of the civil air defense basement in the prior art often sets a sealing plate on the top of the sump, and several drainage holes are opened on the sealing plate, and a sewage pump is arranged at the bottom of the sump, and the sewage pump is connected to a channel extending to the outside of the sump. The water on the ground of the civil air defense basement can be discharged into the sump in time through the drainage hole; however, if the diameter of the drainage hole is small, when there is a lot of sewage on the ground, the sump cannot timely discharge the water on the ground. Collected, if the pore size of the drain hole is large, although the sewage can be discharged into the sump in time, the sewage in the sump produces a large amount of malodorous gas, which is easily emitted from the drain hole to the air defense basement, seriously affecting The environment in the basement of civil air defense, and when there is a lot of sewage, it is often mixed with a lot of sundries, which is easy to cause blockage of the drainage holes, so it needs to be improved
