At present, the direct recharging method used in large quantity at home and abroad is mainly a ground infiltration method and a pipe well injection method. The pipe well injection method is not limited by conditions such as terrain conditions, permeable stratum distribution, underground water level burial depth and the like, occupies less land, wastes less water, is not easily influenced by factors such as ground climate change and the like, and has obvious advantages in foundation pit engineering application. Yu Jianlin and the like provide a design method and a program of a recharging system, and the recharging system is successfully applied to the practice of excavation of a digestion tank foundation pit in the extension engineering of four fort sewage plants in Hangzhou city, and good economic and social benefits are obtained.

Liu Jiansheng and the like explain the connotation, related principles, composition characteristics and control points of the deep foundation pit pumping and grouting integration. Finally, by taking the Haohandanhui junction station as an example, the application of the deep foundation pit pumping and filling integrated design and the operation control in the engineering practice is summarized and analyzed. Luo Huafeng and other above-sea subway stations are used as engineering backgrounds, numerical analysis is carried out on underground water level change and stratum settlement caused by extraction and recharge of second-layer confined water in an upper sea area by using MIDAS numerical calculation software, influences of the thickness of the confined water layer and the length of a recharge well filter tube on extraction and recharge effects are researched, and the method has high guiding value for researching influence factors of the extraction and recharge of the confined water on the environment. Hou Jingyan introduces a construction scheme combining drainage and recharge of 'one-eight-line' engineering of Beijing subway, which not only ensures safe anhydrous operation of subway construction, but also protects limited underground water resources, effectively controls ground settlement caused by drainage, and indicates that the scheme combining pumping and recharging of a foundation pit has obvious economic benefit.
