Water conservancy project foundation pit pipe well combined light well point drainage method
The invention discloses a water conservancy project foundation pit pipe well combined light well point drainage method. The method comprises the following specific methods that 1, a site is surveyed,particularly, firstly, before foundation pit excavation construction operation is carried out on water conservancy buildings such as wharfs and dams, stay wire measurement is carried out on the area of a foundation pit to be excavated and the excavated depth, and meanwhile the distance between the position of the foundation pit to be excavated and the adjacent surface water body is measured; and 2, soil quality data is analyzed, particularly, rainfall data, surface water evaporation amount data and groundwater level change data at the bottom of the foundation pit to be excavated in the past year of the surveyed site are collected and obtained, the obtained data is sorted and analyzed, and a data statistical list and a foundation pit construction position geological sectional view are drawnfor the obtained sorted and analyzed data. The method has the beneficial effects that well point holes are arranged around the foundation pit to be excavated, so that the working efficiency of well point drainage can be improved.
本发明公开了一种水利工程基坑管井结合轻型井点降排水方法，其具体方法如下：第一步勘察场地：首先对于针对码头、堤坝等水利建筑进行挖基坑施工作业前，对需要待挖基坑的面积和所挖的深度进行拉线测量，同时需要对待挖基坑位置与相邻地表水体之间距离进行测量。第二步土质数据分析：收据获取勘察场地近一年的降雨量的数据、地表水分蒸发量的数据以及待挖基坑底部地下水水位的变化数据，然后将所获得的数据进行整理分析，然后对所获得的整理分析的数据绘制数据统计列表和基坑施工位置地质剖面图，有益效果：井点孔设于待挖基坑的周围，从而能够增加井点降排水的工作效率。
