Description

Technical Field

[0001] This invention relates to the field of dewatering system technology, specifically a comprehensive dewatering and recycling system for basement engineering. Background Technology

[0002] With the continuous advancement of modernization, urban development is increasingly pursuing green construction. During the construction phase of the basement project, the dewatering at the bottom of the foundation pit and the drainage of the internal and external structures have not been effectively addressed. During the construction of the basement, the maintenance of the dewatering wells requires a large amount of manpower and resources. If the maintenance is not in place, there may be a risk of leakage in the foundation slab. During the construction of the basement foundation slab structure, the water accumulated in the post-pouring strip of the foundation slab needs to be continuously pumped out. During the construction phase of the basement exterior, the water accumulated in the foundation pit trench and the rainwater coming down from the temporary opening of the tower crane also need to be pumped out manually and with water pumps.

Before the exterior waterproofing work can be carried out, it is necessary to clean the area and wait for a long time. Rainwater coming down from the tower crane openings also falls to various places, which shows that the basement project has not formed an efficient drainage system. Summary of the Invention
