Modularized same-floor drainage device for building and mounting method thereof

Abstract

The invention provides a modularized same-floor drainage device for a building and a mounting method thereof. The drainage device comprises a water collection tank, a standpipe connecting pipe which is penetrated in the water collection tank and a wastewater draining inlet which is formed in a top cover of the water collection tank, wherein a water outlet located in the water collection tank is formed in the standpipe connecting pipe; the wastewater draining inlet is communicated with the water outlet; a transverse sewage pipe is embedded in the upper part of the water collection tank; the bottom of the sewage pipe is not lower than the bottom of the water collection tank; the top of the sewage pipe is not lower than the top cover of the water collection tank; a pedestal pan connecting port is formed at one end of the sewage pipe; a sewage outlet is formed at the other end of the sewage pipe; the sewage outlet is communicated with the standpipe connecting pipe; an axis distance between the pedestal pan connecting port of the sewage pipe and the standpipe connecting pipe is not more than 500mm. The modularized same-floor drainage device for the building provided by the invention has the characteristics of simple structure, scientific design, convenience in use, reliable performance, excellent anti-seepage effect, gathered water seal, odor-returning prevention, less thickness of ground layer and material-saving effect.

Description

technical field [0001] The invention relates to the technical field of building water supply and drainage devices, in particular to a modular same-layer drainage device for buildings and an installation method thereof. Background technique [0002] In the field of building drainage, the riser connection pipe is usually pre-buried in the part where the drain riser crosses the floor, so as to connect the drainage riser of the current layer and the lower layer, so as to avoid the leakage problem caused by the inability to discharge the accumulated water in the subsidence area; but in the specific application process There are the following disadvantages: 1) In order to avoid leakage, the waterproof layer is usually turned up along the pipeline and a water blocking platform is set up, which makes the indoor floor layout look messy, unsightly, and inconvenient for decoration, and the ground water cannot be directly drained away. 2) In the same-floor drainage scheme of the sinking...

Problems solved by technology

[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 drainage riser of the current floor and the lower floor, and avoid the leakage problem caused by the accumulation of water in the sinking area; but in the specific application process However, the following disadvantages occur: 1) In order to avoid leakage, the waterproof layer is usually turned up along the pipeline and a water blocking platform is installed, which makes the indoor floor layout look messy, unsightly, and inconvenient for decoration, and the accumulated water on the ground cannot be directly drained away , resulting in hidden dangers of leakage in the sinking area; 2) In the same-floor drainage scheme of the sinking toilet, because the sewage pipe trap is buried in the interlayer of the floor, the cleaning port of the sewage pipe is useless and cannot be blocked and cleared. Blockage, which will bring a lot of trouble and hidden dangers to users; moreover, the drains of floor drains, bathtubs, wash basins, mop pools, etc. are all provided with separate water seals, and if one drain seal dries up, it will cause indoor odor and endanger health; 3) With the popularization and popularization of residential construction methods, pipe sections and fittings are assembled and bonded to connect drainage standpipes on site, which has the disadvantages that the quality of the joints cannot be guaranteed and the construction period is long; The pipes are buried in the ground layer above the structural floor, resulting in a large thickness of the building ground surface, increasing the structural self-weight load, and wasting materials
