堵水方案 Sewage treatment plant - the water recycling project is blocked shi work party case Water treatment plant - water recycling engineering steel cofferdam construction plan One: engineering content: This project is located in the open area sewage treatment plant in hefei city, which is partially blocked by steel cofferdam in order to block the water in order to keep the water under water. Two: engineering analysis Required for the construction of underwater diving, underwater construction technology, construction equipment, underwater diving equipment and underwater diving construction personnel, project construction management command and so on must be equipped with according to the technical requirements of the project construction organization. This underwater diving construction is carried out through a minor construction work hole into the construction site, and in a silo well below the surface, and in the lower water pipes. And the construction site is full of water for a long time while there is a certain amount of traffic. In this construction environment, construction technology, construction difficulty, construction danger is visible. Underwater diving block construction, which is well-known in the construction industry, is a difficult and dangerous job. Unlike in hohai diving construction environment, hohai diving underwater construction construction is in the open air, the water is crystal clear visibility, up and down at the same time the construction more convenient. In CMC pipeline underwater construction, is in the enclosed underwater construction, construction of water turbidity no visibility, construction all by divers hand touch feeling and long-term accumulation of experience, the construction need to beat around the bush by auxiliary facilities to up and down, up and down one thousand underwater construction accident, rescue them is difficult. There is a certain difficulty and danger in this underwater construction environment. In order to ove
