Secondary drainage waterproofing system for subsided toilet

Abstract

The invention belongs to the technical field of constructional engineering waterproofing, and discloses a secondary drainage waterproofing system for a subsided toilet. The system comprises a caissonand a vertical drainage pipe, wherein a caisson drain pipe embedded into the caisson is connected with the side wall of the vertical drainage pipe; caisson waterproof layers are arranged on the top surface of a bottom plate and the inner side wall surface of the caisson; a slope making layer is arranged on the top surface of the caisson waterproof layer at the bottom and slopes towards the caissondrain pipe; a filling layer is backfilled between the slope making layer and a ground cushion layer; a protecting layer is arranged outside the caisson waterproof layer arranged on the side surface;the caisson drain pipe is covered with a drain board located on the top surface of the slope making layer, and the drain board is fixed by a fixing lead wire pre-embedded in the slope making layer; aseparation net, a water filtering isolation belt and a fixing net are arranged on the peripheral side of the drain board in sequence. According to the secondary drainage waterproofing system for the subsided toilet, the problems of ponding and leakage of the caisson of the subsided toilet are solved fundamentally, water entering the caisson is immediately and smoothly drained by combination of drainage and plugging while waterproofing is strengthened; the system does not occupy indoor space and is simple in structure and convenient to construct, and materials are easily available.

Description

technical field [0001] The invention belongs to the technical field of construction engineering waterproofing, and in particular relates to a water drainage and waterproofing system in a sunken toilet caisson. Background technique [0002] Same-floor drainage is a new type of building water supply and drainage technology that has emerged in recent years, and is mainly used in toilets. Same-floor drainage refers to the drainage method in which the drainage pipes of sanitary appliances do not pass through the floor, and the horizontal drainage pipes are connected to the vertical drainage pipes in the same floor. Compared with traditional interlayer drainage in terms of noise, sanitary corners, maintenance, clear property rights, and building functions, etc. Both have great advantages. The same floor drainage method generally adopts the sunken toilet in China, that is, the structural plate of the toilet is lowered to a distance of 300mm to 400mm from the corresponding floor to...

AI Technical Summary

Problems solved by technology

In view of the fact that once the ground and pipes of the sunken toilet leak, the water flowing into the caisson will have nowhere to go, and will seep out from the weak parts of the bottom and walls of the caisson as time goes by. However, it has been proved that the ground waterproof layer alone cannot resist. Therefore, it is urgent to seek a fundamental solution based on the characteristics of the bathroom
