Drainage riser connector of caisson-type toilet

Abstract

The invention discloses a drainage riser connector of a caisson-type toilet. The drainage riser connector comprises a riser connecting pipe, wherein a lead-in pipe connecting opening is formed in the upper part of the riser connecting pipe; a lead-out pipe connecting opening is formed in the lower part of the riser connecting pipe; the riser connecting pipe is of a structure with an annular waist base extending outwards around the middle section and an annular waist leakage liquid lead-in channel formed on the annular waist base; the annular waist leakage liquid lead-in channel comprises an annular waist leakage liquid collection opening formed in the top surface of the annular waist base, an annular waist leakage liquid lead-in opening which introduced into the riser connecting pipe from the lower part of the annular waist leakage liquid collection opening, and an annular waist leakage liquid diversion cavity connected between the annular waist leakage liquid collection opening and the annular waist leakage liquid lead-in opening; the riser connecting pipe is provided with a diversion baffle for preventing down water from flowing backward into the annular waist leakage liquid lead-in opening in the inner wall corresponding to the position above the annular waist leakage liquid lead-in opening. Compared with the prior art, the secondary drainage problems of drainage caissons at the same layer can be thoroughly solved.

Description

technical field [0001] The invention relates to the field of building drainage systems, in particular to a drainage standpipe connector for a caisson type toilet. Background technique [0002] The toilet drainage of industrial or residential buildings traditionally adopts the lower drainage system, that is, the drainage of the compartment, the drainage branch pipe must pass through the floor, and the branch pipe is hung horizontally on the ceiling of the next floor of the household and connected to the standpipe. This not only invades the space of other residents, but also affects the beauty of the bathroom interior. In particular, each sanitary appliance must be attached with a "P" bend or "S" bend to achieve water sealing. These old "P" bend water seal bends are the same as the old "S" The bend water seal bend is the place where blockage and leakage are most likely to occur, and maintenance is inconvenient. Once leakage will cause unnecessary property losses to the residen...

AI Technical Summary

Problems solved by technology

[0004] 1. If improper operations are performed in construction links such as civil construction, equipment installation, and decoration construction, there will be water accumulation in the backfill layer of the caisson, which will cause water leakage in the caisson or cause water accumulation in the caisson;

[0005] 2. If the water pipe is broken, the joints are not in place or the joints are not strong enough to leak water, the drain pipe is blocked and the ground cannot be dredged manually, etc., you have to pry open the floor to solve it.
