根据建筑给排水工程施工中现场管理问题可知，所安装的管道质量与规格是重中

According to on-site management issues in the construction of building water supply and drainage engineering, the quality and specifications of the installed pipes are the top priority. The purchased pipes must meet the design requirements, and the installation process must also meet the water supply and drainage construction standards. In addition, the pipeline test pressure and medium should be carried out in accordance with the regulations of the design drawing and the acceptance specification. When installing the drainage pipe and rainwater pipe, the corresponding irrigation test should be carried out to ensure smooth drainage. In addition, the installation of the pipe support and hanger should be combined Relevant manuals and specific requirements of construction design to carry out construction. Since most of the indoor water supply and drainage pipes are concealed, the quality management of their construction is more stringent. Concealed pipelines such as water supply must undergo a hydraulic test before being concealed. Acceptance procedures can only be processed after the test results meet the design requirements and construction specifications and other relevant standards. The water supply and drainage system must be purged before delivery to ensure the cleanliness of the pipeline

According to the construction of the building water supply and drainage project site management problems can be seen, the installation of pipe quality and specifications is the top priority, the procurement of pipes must meet the design requirements, the installation process must also meet the water supply and drainage construction standards. In addition, the pipe test pressure and media in accordance with the provisions of the design plan and acceptance specifications, in the installation of drainage pipe and rainwater pipe to carry out the corresponding irrigation test to ensure that its drainage is smooth, in addition to the installation of pipe support hanger to combine the relevant manualand construction design specific requirements for construction. Because most of the indoor water supply and drainage pipes are hidden, the quality management of its construction is more strict. Hidden pipes such as water supply must be water pressure test before concealment, and the acceptance procedures can only be carried out after the test results meet the relevant standards such as design requirements and construction specifications. The water supply and drainage system must be washed before delivery to ensure pipe cleanliness.

According to the site management problems in the construction of water supply and drainage engineering, the quality and specification of the installed pipelines are the top priority. The purchased pipelines must meet the design requirements, and the installation process should also meet the construction standards of water supply and drainage. In addition, the test pressure and medium of the pipeline shall be carried out according to the provisions of the design drawing and the acceptance code. When installing the drainage pipe and rain pipe, the corresponding irrigation test shall be conducted to ensure the smooth drainage. In addition, the installation of pipe supports and hangers shall be constructed in combination with the specific requirements of relevant manuals and construction design. Due to the concealment of most indoor water supply and drainage pipelines, the construction quality management is more strict. Water pressure test must be carried out for concealed water supply pipeline before concealment. Only when the test results meet the design requirements, construction specifications and other relevant standards, can the acceptance procedures be handled. The water supply and drainage system must be cleaned before delivery to ensure the cleanliness of the pipeline
