Plant fermentation drain valve for concealed conduit of caisson type bathroom

Abstract

The invention relates to a plant fermentation drain valve for a concealed conduit, in particular to a plant fermentation drain valve for a concealed conduit of a caisson type bathroom. The plant fermentation drain valve is designed for the first time and used for the concealed conduit of the caisson type bathroom. According to the designed plant fermentation drain valve for the concealed conduit of the caisson type bathroom, the problem that an existing secondary drain hole is easily blocked during construction and follow-up use is solved fundamentally. At the same time, by the adoption of theplant fermentation drain valve for the concealed conduit of the caisson type bathroom, the construction difficulty is also greatly reduced, methods for construction of caisson type bathrooms are expanded, and the wet construction is completely suitable for the caisson type bathroom. As a result, the problem that it is very difficult to ensure smooth operation of the secondary drain hole in the existing wet construction is also solved.

Description

technical field [0001] The invention relates to a drain valve for plant fermentation in a dark tube, in particular to a drain valve for plant fermentation in a dark tube with a cement foam wet backfill structure in an indoor caisson type bathroom. Background technique [0002] The existing caisson-type bathrooms are generally waterproofed with two layers, one is rigid and the other is flexible; at the same time, in order to avoid water leakage in the bathroom, a secondary drainage design is generally adopted; the secondary drainage is to prevent water pipes inside the bathroom from leaking. Water leakage and floor seepage into the owner's house downstairs, and the drainage measures taken. Various factors such as water pipes inside the toilet and other aspects will seep into the caisson and then accumulate in the caisson under long-term use; cement will still leak more or less during long-term immersion. The seepage of water pipes and cement slowly accumulates and becomes a ...
