Description

Technical Field

[0001] The invention relates to the technical field of drainage, and in particular to a subway construction drainage system. Background Art

[0002] Subway is a means of transportation that runs on tracks underground or on the surface. It usually consists of trains that transport passengers on rails. The operation of subways usually has the following characteristics: First, subway lines usually run underground, which can make full use of the city's underground space and reduce the impact on ground transportation. Second, subway lines are usually standardized, with fixed stations and detailed timetables, which are convenient for passengers to take and plan their trips. Third, subway trains are usually powered by electricity, which reduces pollution to the environment. In addition, the subway system can also provide a comfortable, fast and safe riding experience. Subways play an important role in large cities, which can alleviate traffic congestion and improve urban transportation efficiency. Subway systems have been widely used around the world and have become an important choice for people to travel.

[0003] In the construction of urban subways, it is often necessary to pass through economically prosperous areas. In order to reduce the impact on the area, underground excavation is often used. The construction requires the absence of water. Therefore, a subway construction drainage system is needed.

[0004] The existing subway construction drainage system has certain disadvantages when in use. When in use, the existing subway construction drainage system usually digs a sump in the channel, and then builds the sump with concrete sand and gravel, so that the accumulated water in the channel is discharged into the sump, thereby draining the accumulated water in the sump. However, in actual use, it is necessary to build the sump with concrete sand and gravel every time, which not only wastes construction materials and increases economic costs, but also easily causes water accumulation in the process of building the sump, causing debris to block the sump, causing trouble for the workers in building the sump, and reducing the drainage efficiency of the sump.

[0005] Therefore, a subway construction drainage system is proposed. Summary of the invention
