Description

Integral prefabricated toilet caisson and toilet caisson structure

technical field

The utility model relates to an integral prefabricated toilet caisson and a toilet caisson structure, which is applied in an assembled building and belongs to the field of construction engineering drainage.

Background technique

In traditional construction practices, toilet plumbing installation and leakage have always been the most important problems that plague construction and residents. The usual construction methods are: nailing with wooden boxes → on-site measurement and pre-embedding → concrete pouring → removal of wooden boxes after formwork removal → setting casing → installation of main pipe → hanging formwork between casing and concrete structure layer → concrete mortar hole filling structure 1/2 of the layer → remove the iron wire of the hanging formwork and the mold of the hanging formwork → cut all the iron wires into the concrete → pour the last layer of concrete → hand it over to the civil engineering for waterproofing → do a water seepage test. If there is still leakage, remove the original concrete and fill the hole again. This traditional method is more complicated, has many construction procedures, and has a low leakage pass rate. Moreover, at present, PVC pipes are mostly used in the construction of drainage pipes in residential buildings. The material expands with heat and contracts with cold, which is easy to cause leakage and flooding in the later stage. Seriously affect the living quality of residents.
