上海特种基础工程研究所在甬江管道工作井(地下连续墙)工程中利用潜水泵降低地下水位,对于较深的地下透水层采用自流式过滤井的降水形式,施工实践证明效果良好。 在软土地基上进行深基础工程的施工,经常遇到降水问题。根据工程具体情况不同,降低地下水位的目的通常是: Shanghai Institute of Special Basic Engineering used a submersible pump to reduce the groundwater level in the Lanjiang pipeline working well (underground continuous wall) project. For the deep underground permeable layer, the precipitation form of the self-flowing filter well was used, and the construction practice proved to be effective. Construction of deep foundation projects on soft soil foundations often encounters precipitation problems. According to the specific circumstances of the project, the purpose of lowering the groundwater level is usually:
