Vacuum prepressing well point dewatering construction method
The invention discloses a vacuum prepressing well-point dewatering construction method, relates to the technical field of well-point dewatering, solves the problem of high labor consumption in a sealing film laying process, and comprises the following steps: 1, laying a sand cushion layer; 2, mounting a plastic drainage plate; 3, embedding a vacuum distribution pipe; 4, laying a sealing film, wherein the sealing film is laid through a film covering device; 5, mounting a jet vacuum pump; and 6, carrying out vacuumizing. The film covering device in the step 4 comprises a film covering frame, and the film covering frame comprises: a film covering plate; a front pressing roller which is rotationally connected to one end of the bottom of the film covering plate; a rear pressing roller which is rotationally connected to the other end of the bottom of the film covering plate and is parallel to the front pressing roller; and a film rolling roller which is rotationally connected to the side wall of the end, away from the rear pressing roller, of the film covering plate and is parallel to the rear pressing roller. The sealing film can be laid conveniently, sealing connection between adjacent sealing films can be achieved conveniently, the labor force of workers is reduced, and the labor force cost is reduced.
本申请公开了一种真空预压井点降水施工方法，涉及井点降水技术领域，改善了密封膜铺设过程耗费劳动力较大的问题，其包括以下步骤：步骤一：铺设砂垫层；步骤二：安装塑料排水板；步骤三：埋设真空分布管；步骤四：铺设密封膜，采用覆膜装置进行密封膜的铺设；步骤五：安装射流真空泵；步骤六：抽真空；其中，步骤四中的覆膜装置包括覆膜架，覆膜架包括：覆膜板；前压辊，转动连接于覆膜板底部的一端；后压辊，转动连接于覆膜板底部的另一端且与前压辊平行；卷膜辊，转动连接于覆膜板远离后压辊一端的侧壁上，且与后压辊平行。本申请能够方便密封膜的铺设以及与相邻密封膜之间的密封连接，降低了工作人员的劳动力，降低了劳动力成本。
