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 device comprises a water accumulating box, a vertical tube connecting pipe, a lower air pipe which penetrate the bottom wall 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 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 vertical tube connecting pipe is provided with a side discharge connecting member which is communicated with a water closet discharge port, wherein the side discharge member comprises a flat sewage box; an end, communicated with the vertical tube connecting pipe, of the sewage box is provided with a sewage outlet; a side wall of the sewage box is provided with a water closet connecting port whose opening direction is vertical to the axis of the vertical tube connecting pipe. 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 water closet discharge port is convenient to mount and is not liable to block.

Description

technical field [0001] The invention relates to the technical field of building water supply and drainage devices, in particular to a modularized 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 double riser drainage system. Usually, the riser connection pipe and the ventilation pipe connection 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. At the same time, a connecting piece is used to connect the riser connection pipe and the ventilation pipe connection pipe; but in the specific application process, the following disadvantages occur: 1) In order to avoid leakage, the waterproof layer is usually turned up along the pipeline and a water blocking table is set , making the indoor floor layout look messy, unsightly, and inconvenien...

[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; 2) Drain outlets of floor drains, bathtubs, wash basins, mop pools Water seals are installed separately, and 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 housing industrialization construction methods, the installation method of pipe sections and fittings assembled and bonded to connect drain pipes is adopted on site. There are 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, there is a certain distance between the drainage riser and the toilet, and the toilet outlet to the stand The drainage connection horizontal pipe between the pipes 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 be sealed and installed, resulting in water leakage and odor pollution to the indoor environment; 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
