Key Technologies and Case Study of Pit Drainage Construction in Water Conservancy Projects
Abstract：Pit drainage construction is a critical link in water conservancy projects, directly related to the quality, safety, and progress of the project. In view of the increasingly complex geological and hydrological conditions, it is urgent to carry out systematic research and optimization of key technologies for pit drainage. Combined with an example of a large-scale water conservancy hub project, this paper focuses on the analysis of pit dewatering, water cutoff, and monitoring technologies, and puts forward specific countermeasures for optimizing drainage schemes under complex geological conditions, reducing the impact on the construction environment, and improving drainage efficiency and benefits. The case study shows that by adhering to the principle of 'mainly cutting off with combined cutting and drainage', adopting comprehensive measures such as zonal joint dewatering and curtain grouting for water cutoff, and strengthening dynamic monitoring and process control, the pit of the project was successfully implemented with safe, high-quality, and efficient construction, providing valuable references for similar projects.
