Embodiment
[0038] Embodiment Quasi-factory construction method of cast-in-place residential drainage system
[0039] First, make embedded parts in the factory according to specific construction requirements, such as figure 2 Shown is a cast-in. The structure of the embedded part is: there is an oblique annular step (3) between the upper socket nozzle (1) and the lower socket nozzle (4), and the upper socket nozzle (1) and the oblique annular Water-stop rings (2) are provided between the steps (3), and the lower socket socket (4) is fixed to the base (5), and the base (5) is provided with fixing holes (6).
[0040] The slanted annular step (3) is a "Y"-shaped structure, the inclined surface of the slanted annular step (3) is fixed to the upper socket nozzle (1), and the straight line part is inserted into the lower socket nozzle (4) , and fix it with the socket outlet (4).
[0041] Embedded parts mainly include: UPVC floor drain embedded parts, UPVC toilet connectors, UPVC climbing pi...

The invention relates to a cast-in-situ house drainage system quasi-factorial construction method. Before a civil engineering platform template is supported and after bottom bars are paved, according to a principle that standard-house-type toilet drain pipe plan-point positions are relatively fixed, a standard positioning embedded template is utilized to position a draining stand pipe, a vent pipe, a draining branch pipe and a hanging bracket base on a civil engineering platform template; before structure construction is performed, each embedded piece is directly fixed on the civil engineering platform template; when the structure construction is performed, once pouring with structure concrete is performed; each branch pipe is industrially sized and machined, assembled and once mounted in place on site. According to the cast-in-situ house drainage system quasi-factorial construction method, structural reserved holes are reduced, the waterproof quality of a toilet structure and the construction quality of structure and pipeline mounting are improved, the cast-in-situ house drainage system quasi-factorial construction and the structure construction are synchronized, the construction speed is increased, the labors are reduced, no machining exists on site, the costs are saved, and the method is green and environment-friendly.
Description
technical field [0001] The invention belongs to the field of building construction, and in particular relates to a quasi-factory construction method for a cast-in-place residential drainage system suitable for installation of cast-in-place high-rise residential buildings, especially UPVC rigid polyvinyl chloride plastic drainage system pipes with concentrated standard house types. Background technique [0002] Rigid polyvinyl chloride drainage pipe is referred to as UPVC drainage pipe for short. It has the advantages of light weight, smoothness, beauty, small water resistance, flexible assembly, and time-saving and labor-saving installation. It has been promoted rapidly in our country. [0003] The installation of UPVC drainage pipes in the drainage system of high-rise residential buildings with cast-in-place shear wall structures usually adopts the construction process of reserving installation holes in the structure and filling the holes with secondary hanging molds after ...
