Problems solved by technology
[0007] Aiming at the deficiencies of the prior art, the present invention provides a multi-well point linkage dewatering construction method in a large-scale basement in a water-rich sandy soil area, which solves the problem of large-scale basement foundation pit dewatering well construction in construction projects due to its wide range and relatively large area. Large, each tube well dewatering well is independently discharged into the drainage system outside the foundation pit, which will affect the construction during the construction of the basement due to the large number of drainage pipes, and also cause the drainage pipes to rupture due to stumbling, which will affect the construction quality of the basement project. question

The invention discloses a multi-well-point linkage dewatering construction method for a large basement in a water-rich sandy soil area, and relates to the technical field of constructional engineering. The multi-well-point linkage dewatering construction method for the large basement in the water-rich sandy soil area specifically comprises the following steps that firstly, a certain number of sandy soil loss prevention tube well dewatering wells are arranged on a basement bottom plate post-cast strip through calculation according to a geological exploration report; according to the multi-well-point linkage dewatering construction method for the large basement in the water-rich sandy soil area, by innovating multi-tube-well linkage dewatering of the large basement in the water-rich sandy soil area, a dewatering well is arranged at the position of a post-cast strip of a basement bottom plate, and underground water is collected into a water collecting pool in a series connection mode and intensively discharged to a drainage system outside a foundation pit; and auxiliary water (sundries washing and maintenance) before and after concrete construction in the water collecting tank can be utilized, so that the construction progress and the construction quality of the basement project are ensured, the cost is saved, and the aim of maximizing the economic benefit of the project is fulfilled.
Description
technical field [0001] The invention relates to the technical field of construction engineering, in particular to a multi-well point linkage dewatering construction method for a large basement in a water-rich sandy soil area. Background technique [0002] At present, the construction area of residential quarters in my country is getting larger and larger, and the quality requirements are getting higher and higher, and people and vehicles have been separated. Parking of various vehicles is also prohibited in the community. With the improvement of living conditions, people basically In order to meet the needs of using functions, the construction area of the basement is getting larger and larger (civil air defense engineering or underground parking lot). In the whole process of large-scale basement project construction, how to reduce the groundwater level is the primary condition to ensure the quality and construction progress of the basement project. [0003] In the practi...
