衬塑钢管具有水流阻力小、耐腐蚀和使用年限长等特点,被广泛用于给水工程,其在给水管道安装应抓好四个环节的工作。1严格控制标高标高的作用是控制管道的走向和实际位置。在安装立管时,要从顶层预留洞吊一线坠,以控制管道的垂直度;在安装水平管时,在内墙表面弹出中心线,以控制管道的平整度。此方法可确保给水管道的垂直度和平整度始终在设计要求的范围内,其误差为最小。
Lined plastic pipe with water flow resistance, corrosion resistance and long service life and other characteristics, is widely used in water supply project, its installation in the water supply pipe should do a good job in four areas. A strict control of the elevation of the role of the pipe is to control the direction and the actual location. When installing the riser, it is necessary to reserve a hanging crane line from the top to control the verticality of the pipeline. When the horizontal pipe is installed, a center line is ejected on the surface of the inner wall to control the smoothness of the pipe. This method ensures that the verticality and flatness of the feedwater pipe are always within the design requirements with a minimum of error.
