Description

Technical Field

[0001] The invention relates to the technical field of underground structures, and in particular to an urban underground comprehensive pipe gallery with a flood prevention function. Background Art

[0002] The integrated pipe gallery is the direction of sustainable development of urban pipelines. The construction of the integrated pipe gallery can effectively eliminate the "road zipper" and "air spider web" in the city, improve the efficiency of pipeline management, and optimize the use of underground space. The integrated pipe gallery is an underground urban pipeline integrated corridor, that is, a tunnel space is built underground in the city to integrate various engineering pipelines such as electricity, communications, gas, heating, water supply and drainage.

[0003] However, due to the increasing frequency of extreme weather, rainstorms cause serious urban waterlogging, affecting people's normal lives. The prior art uses water storage tanks to store water to alleviate the problem of waterlogging. For example, the patent with patent number CN202010076499.X discloses a sponge city underground integrated pipe corridor for smart city construction, including a pipe corridor channel main body, a drainage well and a box-type water storage tank. The drainage well is arranged on one side of the pipe corridor channel main body and is connected to the ground. The box-type water storage tank is arranged on one side of the pipe corridor channel main body and is connected to the drainage well, and cooperates with a rainwater collection mechanism to absorb, store, infiltrate and purify water when it rains. When needed, the stored water is "released" and utilized, thereby enhancing waterlogging prevention in the corresponding area and promoting the comprehensive utilization of rainwater, further alleviating the pressure of urban waterlogging. At the same time, the rainwater in the rainwater collection chamber can be used as municipal water for greening, road washing, dust reduction, etc. A fresh air supply mechanism is provided to supply air to the internal space of the integrated pipe corridor, thereby improving the internal operation adjustment of the integrated pipe corridor, and thus ensuring the health of maintenance personnel. But there are still the following problems:

[0004] (1) Setting up a water storage tank takes up a large space and requires a lot of construction work. In addition, the water storage capacity is related to the size of the water storage tank, and it is impossible to balance the water storage capacity and the space occupied.
