A pressure relief repair structure for cutting points in basement floor slabs
By pre-embedding pressure relief pipes and filter heads at the leakage points of the basement floor slab, the problem of poor concrete solidification caused by water erosion in traditional repair methods is solved, achieving better leakage sealing effect and airtightness, and improving the waterproof performance of the floor slab.

AI Technical Summary
Technical Problem
In traditional basement floor slab leak repair methods, the water pressure erosion caused by water seeping from below the floor slab during the concrete solidification process leads to poor sealing of the concrete and joints, resulting in unsatisfactory leak sealing effect.
Method used
Pre-embedded pressure relief pipes and filter heads within the cast-in-place structure form a pressure relief mechanism. Groundwater is discharged through the pressure relief pipes, preventing erosion of the solidified concrete and improving its sealing performance.
Benefits of technology
Ensure proper concrete setting, enhance the sealing of the joint between new and old concrete, improve the waterproofing performance of repaired areas, and enhance the waterproofing effect of the base slab.

Abstract
This utility model discloses a pressure relief and repair structure for cut-off points in basement slabs, comprising a cast-in-place body and a pressure relief mechanism. The cast-in-place body is formed within a cut-off groove in the basement slab. The pressure relief mechanism includes a pressure relief pipe and a filter head. The pressure relief pipe is embedded within the cast-in-place body, with its lower end located below the basement slab and its upper end located above the basement slab. The filter head is positioned at the lower end of the pressure relief pipe. The beneficial effects of this basement slab cut-off point pressure relief and repair structure are: by setting up the pressure relief mechanism, groundwater can be discharged through the pressure relief pipe during the solidification process of the cast-in-place body. This avoids the erosion of the solidifying concrete by groundwater under water pressure, as is common in traditional methods, allowing the concrete to solidify normally, resulting in a denser internal structure and improved basement slab repair effectiveness.
