Description

Technical Field

[0001] The utility model relates to the field of underground engineering drainage, in particular to a special splicing drainage structure for underground engineering. Background Art

[0002] Underground engineering construction projects are an important part of the entire civil engineering construction. The construction environment of underground engineering is relatively special. The construction work surface is relatively closed and narrow, and it is very easy to produce water accumulation, which leads to high drainage pressure in the entire underground project and requires frequent drainage. The construction is difficult and risky. Therefore, it is necessary to pay attention to the construction drainage effect of underground engineering, ensure the construction quality and safety of underground engineering, control construction costs, improve construction efficiency, and obtain more economic benefits.

[0003] During the construction of underground projects, it is necessary to drain groundwater and seepage water from rock or soil layers in a timely manner. If the drainage is not timely, water will accumulate in the underground space, thus affecting the progress and quality of the construction. When open channel drainage is used, the construction waste generated during the construction process will accumulate at the bottom of the open channel drainage ditch, causing the drainage ditch to be blocked. In addition, the existing underground space drainage ditches are mostly brick-built or cast-in-place concrete, with complicated procedures, requiring a large number of workers, long construction time, high construction costs, and unable to achieve industrialization and prefabrication. The efficiency is low, the scope of use is narrow, and it cannot be reused. Therefore, a splicing drainage structure dedicated to underground projects is urgently needed to solve the above problems.
