Embodiment 1

[0039] Chongqing Fuling Central Hospital has a construction area of ​​34,000 square meters, 15 floors above ground, 3 floors underground, and a total building height of 62.5m. It is a comprehensive building. The original design of the water supply system of the central hospital used thin-walled stainless steel pipe clamping connection technology, and after design modification, the curved-edge end-face connection of thin-walled stainless steel pipes was adopted. Its water supply system is divided into four subsystems: cold water system, hot water system, direct drinking water system, and soft water system. The pipe diameter is DN15-150mm, and the total number of thin-wall stainless steel pipes used is 10982m. The hot water system is insulated.

[0040] The construction process is divided into the following steps: Familiar with the construction drawings and comprehend the design intent → synthesis of each pipeline → joint review of drawings → accurate on-site measurement and deta...

Embodiment 2

[0103] The outpatient and emergency building decoration project of Guizhou Provincial People's Hospital has a construction area of ​​65,000 square meters, 25 floors in the north, 15 floors in the south, 6 floors in the podium, and a total building height of 99m. It is a large comprehensive building. The water supply system with thin-walled stainless steel pipes with curved edges and end faces is adopted. The water supply system is divided into cold and hot water systems, reclaimed water and reuse systems. The pipe diameters are DN15-DN250. The number of thin-walled stainless steel pipes is not yet total . Among them, the hot water system uses rubber and plastic for insulation, and the reclaimed water and sewage treatment plant are connected to the confluence purification system for reuse. The construction steps of this embodiment 2 are the same as that of embodiment 1. After the completion of the project, most of the pipes of the water supply and reclaimed water system are exp...

Abstract

The invention discloses a construction method for a curve edge end surface of a building water supplying thin-walled stainless steel pipeline. The method comprises steps of pipeline integration, on-site accurate measuring and recording, pipeline curve edge end surface bellmouth processing, thin-walled stainless steel pipe product and pipe fitting connection, preservation and pre-burying, supporting hanger manufacturing, pipeline outer wall processing, pressure testing, pipeline cleaning, pipeline disinfection and installation detection. Compared with the prior art, by the use of the construction method, energy consumption can be reduced, labor production rate can be improved, manpower and material resources can be reduced; and energy consumption can be reduced, environment can be protected and efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of building water supply systems, in particular to a construction method with curved sides and end faces of thin-walled stainless steel pipes for building water supply. Background technique [0002] In the 21st century, my country's construction industry is gradually developing towards the high-end market. Relying on scientific and technological progress, we will continue to promote energy conservation and emission reduction in buildings, and take the road of green and low-carbon economic development, forming a strong technical support to promote the transformation of the development mode of the construction industry. The new connection method of thin-walled metal pipes has always been one of the contents of the overall framework of the 10 new technologies in the construction industry of the Ministry of Housing and Urban-Rural Development. With the current development of high-rise buildings, super high-rise ...
