A modular same-floor drainage device for buildings and its installation method

Abstract

The invention provides a modular same-floor drainage device for buildings and its installation and construction method. The drainage device includes a water collection tank, a standpipe connecting pipe pierced in the water collection tank, and at least one waste water set on the top cover of the water collection tank. Drainage inlet; the riser connecting pipe is provided with a water outlet located in the water collection tank, and the waste water discharge inlet is connected with the water outlet through a water seal mechanism. The modular same-floor drainage device for buildings of the present invention has the advantages of simple structure, scientific design, convenient use, reliable performance, outstanding anti-leakage effect, centralized water seal to prevent back-odor, convenient installation of toilet drain outlet and not easy to be blocked.

Description

technical field [0001] The invention relates to the technical field of building water supply and drainage devices, in particular to a modular same-floor drainage device for buildings and an installation method thereof. Background technique [0002] In the field of building drainage, the standpipe connection pipe is usually pre-buried in the part where the drainage riser passes through the floor so as to connect the current floor and the lower floor drainage riser, but in the specific application process, the following disadvantages appear: 1) In order to avoid leakage, usually Turning up the waterproof layer along the pipeline and setting up a water-blocking table makes the indoor floor layout look messy, unsightly, and inconvenient for decoration, and the accumulated water on the ground cannot be drained away directly, resulting in the hidden danger of leakage in the sinking area; 2) floor drain , Bathtub, washbasin, mop pool, etc. are all individually water-sealed, and if ...

[0002] In the field of building drainage, the standpipe connection pipe is usually pre-buried in the part where the drainage riser passes through the floor so as to connect the current floor and the lower floor drainage riser, but in the specific application process, the following disadvantages appear: 1) In order to avoid leakage, usually Turning up the waterproof layer along the pipeline and setting up a water-blocking table makes the indoor floor layout look messy, unsightly, and inconvenient for decoration, and the accumulated water on the ground cannot be drained away directly, resulting in the hidden danger of leakage in the sinking area; 2) floor drain , Bathtub, washbasin, mop pool, etc. are all individually water-sealed, and if one of the water-sealed drains dries up, it will cause indoor odor and endanger health; 3) With the promotion and popularization of housing industrialization construction methods, pipe sections The installation method of assembling and bonding the pipe fittings to connect the drainpipes has the disadvantages that the quality of the joints cannot be guaranteed and the construction period is long; 4) When the outlet of the side drainage toilet is connected to the drainage riser, due to If there is a certain distance, the drainage connection horizontal pipe between the toilet drain and the standpipe will occupy the indoor space and affect the appearance. Moreover, due to the error between the height of the bathroom floor decoration and the height of the toilet drainage horizontal pipe, the side drainage toilet cannot Sealed installation, resulting in water leakage and odor pollution indoor environment
