水利工程施工中基坑开挖的排水工作,在施工组织中是一项很重要的工作。但是,它往往容易被人忽视。不少工程在组织基坑开挖排水工作时,处理不周地下水不断地渗流入基坑,引起流砂、管涌和边坡失稳等基坑淹没现象,以致基坑报废,延误工期。 Drainage work in excavation of water conservancy projects is a very important task in construction organization. However, it tends to be overlooked. During the excavation and drainage work of many foundation pit excavations, many projects continued to infiltrate into the foundation pit through unsound groundwater treatment, resulting in the flooding of foundation pit such as runoff, piping and slope instability, resulting in the foundation pit being scrapped and the construction period being delayed.
