AI Technical Summary
Technical Problem
In the existing technology, the drainage pipe lacks an effective clamping and fixing structure in the sleeve, which makes it easy to shift and loosen under the impact of water flow, affecting the sealing performance and potentially causing water leakage problems.
Method used
The system employs a combination structure of lower sleeve, upper cover, lower stud, and upper stud. The riser is clamped and fixed by bidirectional inclined studs, ensuring that the riser is accurately positioned and stable on the floor slab over a long period of time.
Benefits of technology
This ensures stable installation of the riser, prevents loosening and displacement, improves sealing performance, and eliminates water leakage.
