Problems solved by technology
[0002] The subway is usually installed in a deep place underground, and the rainwater must be isolated and protected to avoid damage to the electrical equipment in the subway. At present, the mainstream method is to set up gates to block the rainwater. Too much reliance on the stability of the gate structure, once a leak occurs, the equipment in the subway will suffer catastrophic damage

Embodiment Construction
[0012] The technical solutions of the present invention will be described in further detail below through specific implementation methods.
[0013] Such as figure 1 As shown, a subway flood prevention tunnel includes a subway station foundation pit 1, a subway station boss 2 and a drainage system. Channel 3 , the diversion channel 3 is connected to the sewer 4 , as the first external barrier, a large amount of accumulated rainwater flows into the sewer 4 through the diversion channel 3 .
[0014] A number of diversion grooves 5 are provided on the two side walls of the inverted trapezoidal structure, and the diversion grooves 5 are set corresponding to the part of the entrance and exit passages, and each of the diversion grooves 5 on the same side is collected into a water storage pit 6. The water storage pit 6 is located below the bottom of the inverted trapezoidal structure. As the second barrier of the tunnel, the amount of water that can enter is usually very small, and ...

The invention provides a subway submerging-prevention tunnel comprising a subway station foundation pit, subway entrance bosses and a drainage system. The subway station foundation pit is of an inverted trapezoidal structure; a plurality of diversion trenches are formed in the two side walls of the inverted trapezoidal structure, and the diversion trenches in the same side are converged to a waterstorage pit; catchment channels are formed in the two sides of the bottom of the inverted trapezoidal structure and communicate with the outside world through water suction pumps; and diversion passages are formed in the peripheries of the subway entrance bosses and communicate with sewers. The situation that rainwater enters the tunnel is avoided, dredging drainage and diversion are conducted onexternal water, infiltration water is collected and drained, the entering water is converged and pumped out, and thus the safety of tunnel main body equipment is ensured.
Description
technical field [0001] The invention relates to a tunnel structure, in particular to a subway flood prevention tunnel. Background technique [0002] The subway is usually installed in a deep place underground, and the rainwater must be isolated and protected to avoid damage to the electrical equipment in the subway. At present, the mainstream method is to set up gates to block the rainwater. Too much reliance on the stability of the gate structure, once a leak occurs, the equipment in the subway will suffer catastrophic damage. [0003] In order to solve the above existing problems, people have been seeking an ideal technical solution. Contents of the invention [0004] The object of the present invention is to aim at the deficiencies of the prior art, thereby providing a subway flood prevention tunnel with scientific design, good dredging, clear layers and multi-level prevention. [0005] In order to achieve the above object, the technical solution adopted in the presen...
