Well-point dewatering construction method for double-casing vacuum deep well
The invention discloses a well-point dewatering construction method for a double-casing vacuum deep well, and belongs to the technical field of well-point dewatering construction. The method comprises the following steps: step 1, surveying and setting out; 2, drilling and hole forming; step 3, hole cleaning; the double-sleeve equipment is conveyed to a construction site, a crane is used for hoisting and placing, then gravel is filled between the well point and the double-sleeve equipment to serve as a filtering layer, the position, away from the ground by five hundred millimeters, of the double-sleeve equipment is filled and tamped with clay, and the double-sleeve equipment is used for conducting dewatering work. By arranging the outer sleeve and the inner sleeve, the purpose of well point dewatering can be achieved while the vacuum pump vacuumizes the gap between the two sleeves, when the water pump stops working, the vacuum pump can still work independently, the purposes of continuous water collection and dewatering are achieved, and meanwhile the problems that a traditional submersible pump is difficult to install, and the cost is low are solved. And the labor intensity of workers is increased.
本发明公开了一种双套管真空深井井点降水施工方法，属于井点降水施工技术领域。本发明包括以下步骤：步骤一、测量放线；步骤二、钻井成孔；步骤三、清孔；步骤四、降水：将双套管设备运送至施工现场，使用吊机进行吊放，然后在井点与双套管设备之间填充砾石作为过滤层，距离地面五百毫米位置用黏土填充夯实，利用双套管设备进行降水工作。本发明通过设置外套管和内套管能够实现真空泵对两个套管之间的间隙抽真空时同时实现对井点降水的目的，而且在水泵停止工作时，真空泵依然能够独立工作，实现持续集水和降水的目的，同时也避免了使用传统潜水泵安装困难，增加工作人员劳动强度的问题。
