Description

Technical Field

[0001] The utility model relates to the technical field of leak-proof structures, in particular to a leak-proof structure for a reserved hole between a kitchen and a bathroom. Background Art

[0002] In the construction of fixed buildings, the concrete floor of the kitchen and bathroom usually has multiple reserved holes for installing drainage pipes in subsequent projects. In order to avoid leakage at the edge of the drainage pipe, an anti-leakage structure is usually configured when installing the drainage pipe. However, the traditional anti-leakage structure has the following shortcomings when used:

[0003] 1. There is often a gap between the traditional anti-leakage structure and the drain pipe. The drain pipe is easily shaken by force during drainage, causing the connection to loosen.

[0004] 2. The traditional anti-leakage structure is inconvenient to install and disassemble the drainage pipe, which is not conducive to later maintenance.

[0005] Therefore, we propose an anti-leakage structure for the reserved holes between kitchen and bathroom. Utility Model Content
