What are the basic principles to follow when installing ink tubes? Below, the editor will explain to everyone.
(1) Water supply and gas pipeline engineering should be constructed according to the design documents and construction drawings. Ductile iron pipes and fittings should comply with the relevant national product standards (GB 13295) or international standards (ISO 2531), and should have a factory certificate of conformity. Pipes used for drinking water should not pollute the water quality. The construction of water and gas pipeline projects should comply with relevant national and local regulations, and project acceptance should comply with relevant national standards and specifications.
(2) Before the construction of water and gas pipeline engineering, the design unit should conduct design disclosure and conduct investigation and research according to the construction needs to grasp the following situations and information along the pipeline:
1) The terrain, topography, buildings, various pipelines, and other facilities on site;
2) Engineering materials, hydrogeology, engineering land and construction water, drainage conditions, power supply conditions, etc;
3) Supply conditions for engineering materials and construction machinery;
4) When constructing in surface water bodies or along the shore, it is necessary to have knowledge of the hydrological and shipping data of the surface water; When carrying out construction in cold regions, it is necessary to have knowledge of the freezing and flowing ice of surface water;
5) Other information and data based on the characteristics of the project and site conditions.
(3) Drainage construction design should be prepared for those who need to drain water. Construction drainage should consider a series of drainage related issues such as not affecting traffic, not damaging roads, farmland, riverbanks, and other structural buildings.
