Deep foundation pit dewatering and drainage and leakage water plugging method for reclamation area
The invention provides a deep foundation pit dewatering and drainage and leakage water plugging method for a sea reclamation area. The method mainly comprises the steps of surveying and setting out, punching, well point pipe installation, sand filling, main pipe laying, pumping equipment entering, well point pipe and main pipe communication, pumping and leakage water treatment. According to the technical scheme of the method, the foundation pit in the sea reclamation area is subjected to dewatering and drainage through the light well point dewatering process, the dewatering effect is good, the water level of the foundation pit is reduced to the designed depth, the interior of the foundation pit is kept dry, the foundation pit is convenient to excavate, then the water seepage position in the foundation pit is treated through a drainage pipe drainage or chemical grout injection blocking method, the dry environment in the foundation pit is further kept, and excavation of the foundation pit is prevented from being affected.
本发明提供一种填海区深基坑降排水和渗漏水封堵方法，该方法主要包括：测量放线、冲孔、安装井点管、填砂、铺设总管、抽水设备进场、井点管与总管连通，然后进行抽水，最后进行渗漏水处理，本发明技术方案通过采用轻型井点降水工艺对填海区基坑进行降排水，降水效果好，使得基坑水位降至设计深度，基坑内部保持干燥，便于开挖基坑，然后采用引流管排水或注入化学浆液封堵的方法对基坑内的渗水处进行处理，进一步保持基坑内部干燥环境，防止影响基坑的挖掘。
