水利工程中河道软基超大深基坑降水质量控制技术的分析

Analysis of Dewatering Quality Control Technology of Super Deep Foundation Pit on River Soft Foundation in Hydraulic Engineering

水利工程施工环境复杂,容易出现河道软基现象,并存在地下水、潜水等问题,在基坑开挖过程中可能引发渗流事故,阻碍工程建设。基于此,以某水利工程为展开分析,首先简单阐述了工程概况,总结案例工程基坑排水措施,进一步结合工程实际指出河道软基超大深基坑降水施工技术在水利工程中的具体应用,旨在运用井点降水法进行河道软基超大深基坑降水,供类似工程参考。

The construction environment of water conservancy project is complex,which is prone to the phenomenon of river soft foundation,and there are problems such as groundwater and phreatic water.Seepage accidents may be caused in the process of foundation pit excavation and hinder the project construction.Based on this,taking a water conservancy project as an example,this paper first briefly expounds the general situation of the project,summarizes the drainage measures of the foundation pit of the case project,and further points out the specific application of the dewatering construction technology of the super deep foundation pit of the river soft foundation in the water conservancy project in combination with the engineering practice.The purpose is to use the well point dewatering method to dewatering the super deep foundation pit of the river soft foundation,which can be used as a reference for similar projects.
