Embodiment 1
[0074] 1. For a 2×60MW natural gas distributed energy station project in a high-tech zone, the foundation treatment adopts water-covered vacuum preloading, the water cover height is 1.5 meters, and there is a fill layer of nearly 4 meters under the membrane. Large, causing the relative displacement between the sealing film and the monitoring pipe to be close to 1.5 meters during construction. Since the drainage board is constructed by the way of leading holes, there are many holes under the sealing film. Most of the holes have been treated with sand filling and compaction before laying the sealing film, but there are still some holes that are preloaded under vacuum due to the vacuum. Run, and the sealing film will be broken by suction. Since the hole is close to 1.5 meters below the water cover, it is difficult to repair the sealing film. After repeated research, the underwater double-glue sealing method of this embodiment is adopted for processing. The specific implementati...

The invention discloses a vacuum prepressing underwater double-adhesive film repairing method. The vacuum prepressing underwater double-adhesive film repairing method comprises the following steps ofleveling a flexible cloth pad and a repairing film on a film pressing plate, and fixing the flexible cloth pad and the repairing film through fixing clamps; wiping a hole to be clean with a towel under water, and filling and blocking the hole with a sand bag; applying adhesive special for a vacuum film to the middle below the repairing film, and applying special underwater sealant to the peripherybelow the repairing film; and finally, putting the repairing film into the hole for gluing through the film pressing plate. The invention further discloses a vacuum prepressing underwater double-adhesive film repairing device. The vacuum prepressing underwater double-adhesive film repairing device comprises the film pressing plate. The bottom face of the film pressing plate is square; the two sides of the film pressing plate are each provided with the corresponding fixing clamp; and a handle rod is arranged above the film pressing plate and movably connected with the film pressing plate. Thevacuum prepressing underwater double-adhesive film repairing device and method have the beneficial effects that construction is easy to conduct; the problems that the construction period is prolonged,and the construction cost is obviously increased are avoided; and meanwhile, the problem of conducting film repairing in an underwater environment with the overlying water depth being 0.3 m or abovecan be effectively solved.
Description
technical field [0001] The invention belongs to the technical field of vacuum preloading soft ground treatment, and in particular relates to a vacuum preloading underwater double-glue film repairing device and method. Background technique [0002] Vacuum preloading method is an effective method to strengthen soft clay foundation, and it has been widely used in soft foundation treatment projects in coastal areas of my country. The effective sealing of the surface sealing film is a necessary condition for obtaining a durable and stable vacuum degree. Only by ensuring the sealing of the sealing film can the effect and quality of vacuum preloading be guaranteed. Therefore, the sealing performance of the sealing film is the key to the quality control of vacuum preloading. The vacuum preloading operation has the following characteristics: 1. High vacuum pressure: the vacuum degree under the membrane usually reaches above 80kPa. Usually, in order to improve the quality of the vacuu...
