Description

A sunken bathroom caisson overall overhead waterproof structure

technical field

The utility model relates to the technical field of waterproof structures, in particular to an integral overhead waterproof structure of a sunken toilet caisson.

Background technique

In order to flexibly arrange bathroom facilities and meet humanized living needs, most residential buildings use sunken toilets. People pay more and more attention to the waterproofing of bathroom caissons and backfilling of caissons. This is related to the long-term waterproofing of bathrooms after occupancy. The sunken toilet caisson is when the main body is built, and the toilet structural layer is partially or wholly sunk away from the corresponding floor to a certain height. The sanitary appliance drainage pipe and the drainage branch pipe do not pass through the structural floor of this floor to the lower space, and are laid and connected with the sanitary appliance on the same floor. Into the drainage pipe system, and then backfill or elevate. The structural facet only needs to set a hole for the drainage standpipe to pass through. It belongs to the same floor drainage toilet. The existing construction methods of the sunken toilet caisson generally include caisson backfill method and caisson overhead. However, there are many problems in the backfilling method and the overhead method. One is that the drainage is not smooth, and there are hidden dangers of human factors damaging the waterproof layer during construction, which is easy to leak, which affects the function, appearance and neighbor relationship of the house. Second, the backfilling material itself is very heavy. It brings perennial overload to the bottom plate of the caisson, which is easy to cause cracks in the bottom plate; third, the slag in the backfill material is extremely corrosive, contains sulfide, is not environmentally friendly, and is easy to corrode water pipes; fourth, the existing backfill materials are all loose. There is a 30cm-high overhead layer in the caisson, which will easily cause a large amount of water in the caisson to breed bacteria and produce odor after a long time.
