Water stop section for crossing floor layer installation of building drainage pipeline and installation method of water stop section

Abstract

The invention discloses a water stop section for the crossing floor layer installation of a building drainage pipeline and an installation method of the water stop section. The water stop section includes a water stop section body, a flange gland, a sealing ring sleeve, a sealing rubber pad, a sealing rubber ring and a fastening bolt, the water stop section body and the flange gland are assembledin a fastened mode by the fastening bolt, the inner cavity of the water stop section body is connected with the sealing ring sleeve by the sealing rubber ring in a sealed mode, and the sealing ring sleeve and the flange gland are connected in a sealed mode through the sealing rubber pad inside of the sealing ring sleeve. The risk that water leakage is prone to occurring at openings in the two endsof an embedded connecting pipe or a center-adjustable embedded connecting pipe structure is avoided, a bolt connection fastening method of a T-shaped groove formed in the water stop section body witha cross groove of a flange pressure plate long bolt hole is adopted, when the position of the water stop section poured on a reinforced concrete floor is deviated, the installation position of the pipeline can be conveniently adjusted in any horizontal direction by displacing adjustment to ensure the verticality of the vertical pipe installation, the product structure is simplified, the manufacturing cost is reduced, and the efficiency of installation and construction are improved.

Description

technical field [0001] The invention relates to the technical field of building drainage, in particular to a water stop joint used for installing building drainage pipes through floor floors and an installation method thereof. Background technique [0002] The drainage standpipe of the building drainage system usually needs to pass through the floor layer during the installation process, and the crossing part is generally in the bathroom. In order to prevent the accumulated water on the floor of the toilet from leaking to the toilet on the lower floor through the gap between the outer wall of the pipeline and the structural floor, the following water-stopping measures are often adopted in the design and construction: [0003] 1. Reserve pipe installation holes when pouring in-situ floor slabs. After the pipes are installed, use cement mortar for secondary grouting to close the gap between the pipes and the reserved holes; [0004] 2. The steel casing is embedded in the floo...

Problems solved by technology

However, there are still: 1) The pipes are connected to both ends of the pre-embedded pipe respectively, and there are two sealed interfaces, which increases the risk of leakage; 2) The body of the pre-embedded pipe is in contact with sewage and waste water, which will affect its service life due to corrosion; 3) Due to the alignment of the center-adjustable embedded pipe, the upper and lower interfaces may be dislocated, which will affect the water flow pattern and drainage performance in the drainage standpipe; 4) The lower flange of the embedded pipe is connected with a threaded hole to fasten the flange. In actual engineering, it is found that , if the thread hole slips due to carelessness during installation, the pre-embedded connecting pipe will be scrapped, and it will be chiseled off and replaced again, with a huge workload; If it is fastened by bolts, it is necessary to fill the T-shaped slot with foam plastic or other fillers in actual engineering to prevent it from being filled with cement mortar during pouring. If the T-shaped slot is accidentally filled with cement mortar, it will be very troublesome to pick and chisel; 6) Structure More complicated and expensive
