1955年冬季,我们在修复华阳闸工程中,使用了‘井点系统’来降低地下水位,收到了十分满意的结果,为我国水利工程施工技术创造了新的一页。‘井点系统’降低地下水位的施工方法,在苏联和其他国家早已广泛地采用,这种方法在实践上有许多独特的优点。降低水位工作,是通过布置在基坑四周的:(一)吸水总管管路,(二)吸水‘井点’管群,(三)真空泵设备(包括抽水机)来实现的。在形式和作用方面它不同於一般的排水方法。因此我国工程师们把这种设备称为‘井点系
In the winter of 1955, when we repaired the Huayang Sluice project, we used a well point system to lower the water table and received very satisfactory results, creating a new page for the construction of water conservancy projects in China. Well point system The method of lowering groundwater level has been widely adopted in the Soviet Union and other countries. This method has many unique advantages in practice. The work of lowering the water level is realized by arranging around the pit: (1) suction main pipe, (2) water absorption well point pipe group, and (3) vacuum pump equipment (including water pump). It differs from the general drainage method in form and function. Therefore, our engineers call this equipment as "well point system
