Abstract

The invention discloses a W-type flexible anti-seismic cast iron drainage pipe construction method. The method sequentially includes a, measuring and wiring, namely measuring, wiring and positioning according to construction drawings, arranging an embedded sleeve penetrating floor slabs and walls with one-size-larger diameter than the required diameter; measuring and wiring according to the construction drawings, and determining the required pipe length according to results; and determining positions for arranging supports and suspensions according to the required pipe length; b, mounting the supports and suspensions, namely arranging vertical pipe supports and suspensions, fixing a drainage vertical pipe onto a building bearing structure through the supports arranged in layers; c, mounting the pipe; d, mounting branch pipes; e, connecting with other pipes, auxiliary members and water equipment; f, performing a water filling test; g, performing a water test; h, performing a ball-passing test.

Description

technical field [0001] The invention relates to a construction method, in particular to a construction method of a W-shaped flexible anti-seismic cast iron drainage pipe. Background technique [0002] Building drainage is an important functional part of construction engineering. The traditional drainage pipe construction method has disadvantages such as difficult installation, short service life, high noise, no corrosion resistance, and easy aging. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a construction method that can be constructed synchronously, has high utilization rate of pipe materials, facilitates clearing of pipes, and shortens construction period. [0004] In order to achieve the above object, the present invention adopts the following technical scheme: a construction method of a W-shaped flexible anti-seismic cast iron drainage pipe, which comprises the following steps in turn: [0005] a) Meas...
