safety and civilized construction assurance measures I Preparation basis   1.

Under the unified management of the underground comprehensive pipe gallery headquarters, each project department takes its own responsibilities, and selects the waterproof engineering construction team with excellent technology, qualification and many years of construction experience to be responsible for the waterproof construction of their respective sections.

See the section construction organization design for the allocation of main construction management personnel and technical personnel of the project management department.

The waterproof design of the comprehensive pipe gallery of the project is wrapped with pressure-sensitive reaction self-adhesive polymer waterproof coiled materials around, and a waterproof coiled material protective layer is set outside the waterproof coiled materials on the side walls and roof on both sides of the comprehensive pipe gallery.

The design service life of the structures of the project is 100 years, and the underground waterproof design grade standard is grade II; The comprehensive pipe gallery shall be provided with a deformation joint every less than 20m.
