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.
Description
technical field [0001] The present application relates to the technical field of well point dewatering, in particular to a construction method for vacuum preloading well point dewatering. Background technique [0002] Before building construction on the foundation, it is necessary to dewater the foundation to lower the groundwater level in the foundation. For the precipitation of soft soil foundation, the vacuum preloading method is generally used to reduce the groundwater level of the foundation and increase the effective stress of the foundation at the same time. [0003] The construction steps of the vacuum preloading method mainly include: 1. laying sand cushion; 2. inserting plastic drainage board in soft soil foundation; 3. burying vacuum distribution pipe, connecting plastic drainage board with vacuum distribution pipe; 4. laying sealing 5. Install a jet vacuum pump connected to the vacuum distribution pipe; 6. Vacuumize. [0004] In view of the related technologies...
