Description

Technical Field

[0001] The utility model relates to the technical field of soft soil foundation treatment, in particular to a repair device for vacuum pre-pressed sealing membranes. Background Art

[0002] Currently, a vacuum preloading method is used to treat soft foundations on a site. The surface of the reinforced soft foundation area, covering tens of thousands of square meters, is covered with a sealing membrane. A vacuum is then drawn underneath the membrane. Once the vacuum reaches the design requirement, a thick layer of water is often applied to the membrane to increase the load on the surface and protect it from aging and cracking due to exposure to sunlight and cold. Vacuum preloading takes a long time, typically three to five months. Furthermore, due to quality issues with the sealing membrane, such as numerous pinholes and insufficient ductility, as well as improperly sealed drainage holes and excessive differential settlement caused by uneven geological conditions within the area, these issues can cause localized holes in the sealing membrane, ultimately leading to damage and failure of the vacuum preloading process. Therefore, repairing the sealing membrane is crucial, and any damage should be promptly repaired. Existing sealing membrane repair devices for vacuum preloading soft foundation treatments lack the ability to adjust to holes of varying sizes, requiring manual pressure and adhesion. This increases labor intensity and results in poor adhesion and adhesion. Utility Model Content

[0005] The above-mentioned structural design is adopted, and the threaded rod is driven to rotate by rotating the motor, and the threaded sleeve is driven to move up and down along the threaded rod, thereby adjusting the distance between the clamping components. It can clamp repair diaphragms of different sizes, thereby increasing the applicability of the device and improving the repair effect of the sealing membrane. The lifting plate is driven downward by the hydraulic cylinder to press and repair the sealing membrane, which has a good bonding repair effect on the sealing membrane, reduces the labor intensity of the staff, and improves the work efficiency of the staff.

[0007] With the above structural design, after pulling the pull rod, the repair diaphragm is extended into the gap between the U-shaped frame and the clamping plate. After loosening the pull rod, the repair diaphragm is clamped by the reset spring. The operation is simple and easy to install and disassemble.

[0008] Preferably, rubber pads are provided on the inner side of the U-shaped frame and the side surfaces of the clamping plate.

[0009] The above structural design makes the device fit more closely with the repair diaphragm, increases the friction between the two, and makes the repair diaphragm less likely to shift.

[0010] Preferably, four support rods are equidistantly arranged on the side wall of the threaded sleeve, and sliders at the lower ends of the support rods are slidably connected in corresponding sliding grooves.

[0011] With the above structural design, considering that most repair diaphragms are circular, setting four clamping components in different directions can enable the repair device to better clamp the repair diaphragm, while increasing the number of contact points between the repair diaphragm and the sealing membrane, resulting in a better repair effect.

[0012] Preferably, a moving wheel is installed at the lower end of the support rod.

[0013] The above structural design makes it easy for construction workers to move the device to the sealing membrane to be repaired, making it convenient to move the device.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] By rotating the motor to drive the threaded rod to rotate, the threaded sleeve is driven to move up and down along the threaded rod, and then the distance between the clamping components is adjusted so that it can clamp repair membranes of different sizes, increasing the applicability of the device and improving the repair effect of the sealing membrane. The lifting plate is pressed down by the hydraulic cylinder to press and repair the sealing membrane, reducing the labor intensity of the staff and improving the work efficiency of the staff.
