Modularization same-layer drainage device for high-rises and mounting method thereof

Abstract

The invention provides a modularization same-layer drainage device for high-rises and a mounting method thereof. The drainage device comprises a water accumulating box, a vertical tube connecting pipe which penetrates in the water accumulating box, a lower air pipe which penetrate the bottom wall of the water accumulating box and is not higher than the top of a top cover of the water accumulating box, an upper air pipe which is installed on the top cover of the water accumulating box and is communicated with the inner part of the water accumulating box; and a waste water discharge inlet which is installed in the top cover of the water accumulating box; a gas passageway is installed between the upper air pipe and the lower air pipe; a vertical tube connecting pipe is provided with a water outlet which is positioned inside the water accumulating box; the waste water drainage inlet and a water outlet are communicated; the top of the lower air pipe is not lower than the highest point of the water outlet; a transversely arranged sewage pipe is embedded in an upper part of the water accumulating box; the axial distance between a water closet connecting port of the sewage pipe and the vertical tube connecting pipe is not larger than 500mm. The modularization same-layer drainage device for high-rises of the invention has a simple structure, scientific design and reliable performance and is convenient to use; the device has excellent seepage-proofing performance; stink proofing is realized by concentrated water sealing; the ground layer thickness is small and material is saved.

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 high-rise buildings and an installation method thereof. Background technique [0002] The drainage system of existing high-rise buildings mostly adopts a double riser drainage system. Usually, the riser connecting pipe and the ventilation pipe connecting pipe are pre-buried in the part where the drainage riser and the ventilation pipe pass through the floor, so as to connect the drainage riser and the lower floor. Ventilation pipe, at the same time, the connecting piece is used to connect the riser connecting pipe and the ventilating pipe connecting pipe; however, in the specific application process, the following disadvantages appear: 1) In order to avoid leakage, the waterproof layer is usually turned up along the pipe and a water blocking platform is installed , making the indoor floor layout appear me...

[0002] The drainage system of existing high-rise buildings mostly adopts a double riser drainage system. Usually, the riser connecting pipe and the ventilation pipe connecting pipe are pre-buried in the part where the drainage riser and the ventilation pipe pass through the floor, so as to connect the drainage riser and the lower floor. Ventilation pipe, at the same time, the connecting piece is used to connect the riser connecting pipe and the ventilating pipe connecting pipe; however, in the specific application process, the following disadvantages appear: 1) In order to avoid leakage, the waterproof layer is usually turned up along the pipe and a water blocking platform is installed , making the indoor floor layout appear messy, unsightly, and inconvenient for decoration, and the accumulated water on the ground cannot be drained directly, resulting in hidden dangers of leakage in the sinking area; The water trap is buried in the interlayer of the floor slab, causing the cleaning port of the sewage pipe to be useless and unable to clear the blockage. Once blocked, this will bring a lot of trouble and hidden dangers to the user; again, floor drains, bathtubs, wash basins, mop pools, etc. Water seals are installed separately for the drain outlets. If the water seal of one drain outlet dries up, it will cause indoor odor and endanger health; 3) With the promotion and popularization of residential construction methods, pipe sections and fittings are assembled and bonded to connect the drainpipes on site. The installation method has the disadvantages that the quality of the joints cannot be guaranteed and the construction period is long; 4) In the existing technology, the sewage pipes are mostly buried in the ground layer above the structural floor, resulting in a large thickness of the building ground surface, increasing the self-weight load of the structure, and wasting materials; 5) At present, the special ventilation pipe and the drainage standpipe are connected by an H-shaped connecting pipe. The sewage spirals vertically along the pipe wall in the drainage riser, and an inertial water curtain or water film is easily formed at the H-shaped connecting opening to block the connection. The opening of the ventilation pipe causes water to enter the H-shaped connecting pipe and enter the ventilation pipe. The ventilation effect is not good, and water enters the ventilation pipe; The center distance of the pipe must meet the requirements of a certain size, usually not less than 260mm, resulting in a large space occupied by the pipe, and because the two vertical pipes must pass through the structural floor to make a reserved hole in the floor, the distance between the two holes is small, and the two The waterproof layer between the pipes is very difficult to construct, and it is often a leak-prone area
