基坑降水的目的是为基础工程施工提供地下工程作业条件及保证基坑边坡的稳定。降水方式及方法的选择须依据拟建工程建筑物(或构筑物)基础的工程特点要求,充分研究拟建场地的工程地质条件、水文地质条件和环境条件,使其方式方法既安全可靠又便于施工并经济合理。
The purpose of the foundation pit dewatering is to provide underground engineering working conditions for the construction of foundation works and to ensure the stability of the foundation pit slope. The selection of precipitation methods and methods shall be based on the engineering characteristics of the foundation of the proposed project building (or structure), and fully study the engineering geological conditions, hydrogeological conditions and environmental conditions of the proposed site so that the methods and methods are safe and reliable and convenient for construction. And economic and reasonable.
