Establish the quality assurance system and post responsibility system for steel casing pipe, improve the quality management system, clarify the division of responsibilities, implement the personnel, ensure the efficient operation of the system.
Implement omni-directional and whole-process control of project quality; To the construction process of human, machine, material, law and environmental five elements of the guarantee measures for clear and implementation. Before the steel casing tube installation, the geometry of the steel casing tube itself, the thickness of the steel casing tube, the material, the waterproof wing ring and the welding quality should be strictly checked and inspected.
Basic parameters such as the base line elevation of the steel casing tube support need to be verified repeatedly to ensure accuracy. Strict "plan first, disclosure first, sample first" principle, strict quality "three inspection system". The steel casing tube port arc should be thick to ensure no deformation after cutting.
