Waterproofing and thermal insulation construction method for building water supply and drainage and heating engineering

Abstract

The invention discloses a waterproofing and thermal insulation construction method for building water supply and drainage and heating engineering. The method includes the following steps of S1, layinga pipeline route, wherein on-site route lofting and laying is performed on water supply and drainage and heating engineering pipelines according to design; and S2, prefabricating and machining the pipelines, wherein the pipelines are prefabricated and machined according to the pipeline route. The waterproofing and thermal insulation construction method for building water supply and drainage and heating engineering includes the steps of laying the pipeline route, prefabricating and machining the pipelines, installing the pipelines, testing the water pressure, performing corrosion prevention and thermal insulation on the pipelines, performing flushing and disinfecting and laying the waterproofing influence treatment, and the method includes the waterproofing and thermal insulation construction of the pipelines for the water supply and drainage and heating engineering, facilitates the flow construction, and is good in waterproofing and thermal insulation effect; furthermore, the flushingand disinfecting step includes the following substeps of introducing water for flushing, and performing disinfecting and secondary flushing, wherein the water with free chlorine with the injection concentration of 20-30 mg / L is adopted during disinfecting, and disinfecting is performed; and the cleaning and disinfecting effect is good, and it is ensured that the water for water supply and drainage and heating engineering is safe.

Description

technical field [0001] The invention belongs to the technical field of building water supply and drainage and heating engineering construction, and specifically relates to a waterproof and thermal insulation construction method for building water supply and drainage and heating engineering. Background technique [0002] Works for water supply, wastewater discharge and water quality improvement. Divided into water supply works and drainage works. The ancient water supply and drainage projects only transported water for the city and drained the precipitation and sewage in the city. Modern water supply and drainage projects were developed to control the prevalence of infectious diseases such as typhoid, cholera, and dysentery in cities and to adapt to the development of industry and cities. Modern water supply and drainage projects have become the basic facilities for controlling the prevalence of water-borne infectious diseases and environmental water pollution, one of the i...

Problems solved by technology

But nowadays, there is no uniform, standardized and specific construction method for waterproofing and thermal insulation construction for building water supply, drainage and heating engineering. Therefore, in actual construction, it is inevitable that the construction operation is relatively random, irregular, and the construction efficiency is low. Many problems such as poor waterproof and thermal insulation effect
