Information

Project overview: the Pearl River Delta water resources allocation project is one of the 172 major water-saving water conservancy projects deployed by the State Council. The total length of the water transmission line project exceeds 113 kilometers, and a total planned investment of about 35.4 billion yuan is the largest investment, the longest water transmission line and the widest water resources distribution project in the history of Guangdong Province.Shield pipe sheet is the main assembly component of shield construction, which is the innermost barrier of the tunnel, and bears the role of resisting soil layer pressure, groundwater pressure and some special loads.

The durability of shield duct sheet in the project has a very important impact on the project quality, so it is necessary to provide high-quality waterproof and corrosion protection for shield duct pieces.

Main use of Jiagushi: concrete shield pipe sheet waterproof and anticorrosion

Project address: Shenzhen City, Guangdong Province

Construction time: in 2020.03 to start

Construction bid section: including test section, standard A1, standard A2, standard A3, standard B2, standard B3, etc

Construction steps: the first time wet the first step (150ml / m2) Second sprinkling second sprinkling (100ml / m2) The third time of water sprinkling and wet maintenance is completed for 3 days

Effect evaluation: The patented technology —— water-based permeable inorganic water waterproof agent has significantly improved its strength, seepage resistance, chlorine resistance and anti-corrosion properties with its unique advantages.
