TECHNICAL FIELD

[0001] The utility model relates to building construction technical field especially a kind of old community reconstruction toilet hole plugging structure. BACKGROUND

[0002] With the development of city, many old communities have existed for many years, and the sewer pipes of the communities have a long service life, often facing problems such as aging, wear and tear, and blockage. These problems not only affect the daily life of residents but also may cause environmental pollution. In the reconstruction of old community building, because it is required to replace the main pipe by local demolition, the waterproof treatment after replacement puts higher requirements on the construction party.

[0003] In the reconstruction of old community building, because it is required to replace the main pipe by local demolition, in order to ensure that the new and old waterproof can normally play its use function, the system adopts the leakage repair method combined with "prevention, drainage, interception and plugging". "Prevention" means to prevent water from invading the structure layer by waterproofing the structure of the water leakage part, which also protects the structure. "Drainage" means to directly drain the water leakage by water diversion. In the case of narrow construction surface or for some reason, the water source cannot be cut off from the root, so the drainage system is combined. "Interception" means to cut off the water source within a specified range so that the water does not leak to the surrounding leakage part. "Plugging" means to strengthen the structure of the water leakage part and to waterproof the structure.

[0004] Currently, when replacing the main pipe, the old pipe needs to be disassembled, which may damage the original waterproof coating around the old pipe during disassembly of the old pipe, so that the new and old waterproof joints are prone to leakage in the future.
