Description

Technical Field

[0001] The utility model relates to a positioning and punching auxiliary device, in particular to a positioning and punching auxiliary device for curtain construction, belonging to the technical field of grouting assistance. Background Art

[0002] Generally speaking, water-stop curtain is the general term for the water-stop series around the main body of the project. It is a continuous water-stop body used to prevent or reduce the inflow of groundwater from the side walls and bottom of the foundation pit into the foundation pit. The top of the curtain is connected to the concrete gate bottom plate or the dam body, and the bottom is penetrated to a certain depth in the relatively impermeable rock layer to prevent or reduce the infiltration of groundwater in the foundation. After the curtain is cast, holes are usually drilled to set traction cables to extend to the bottom surface of the outside of the curtain to ensure the stability of the curtain and prevent it from tipping over. However, the outside of the existing curtain lacks a structure for positioning the holes, which may lead to different drilling angles at different positions, resulting in different extension directions of the traction cables set on the inside, resulting in uneven force at different positions of the curtain, thereby affecting the structural stability of the enclosure when in use. It can be seen that there is currently no better way to position the water-stop curtain well during construction.

[0003] At present, after searching, the Chinese invention patent with the announcement number CN107190705B discloses a device and method for plugging wide cracks by using drill rod impact, including multiple cement sand balls thrown into the curtain grouting hole with wide cracks, and a plug is arranged in the curtain grouting hole, the lower part of the plug matching with the cement sand ball is a flat cone, and the upper part of the plug is a cylinder and connected to the drilling rig outside the curtain grouting hole through the drill rod. However, the steps are cumbersome, and it is not easy for the plug to press the cement sand ball to fully squeeze it into the solution cavity or crack to fill it tightly.

[0004] Therefore, the key to solving the above technical problems is to develop a positioning and punching auxiliary device for curtain construction that is simple to operate, stable and reliable. Summary of the invention

[0006] Another invention purpose of the utility model is to achieve the stability of the water-stop curtain enclosure structure, so as to avoid the situation where the water-stop curtain enclosure structure collapses due to long-term squeezing by the outer soil body, endangering the safety of construction workers in the foundation pit.
