Contributing to cost reduction and environmental impact reduction in bridge reinforcement construction!

In bridge reinforcement work at harbors, efficient operations and consideration for the environment are required. In particular, temporary closures in areas where water levels and flow rates fluctuate are crucial for ensuring a safe working environment and minimizing impacts on the surrounding environment. Traditional methods have faced challenges due to the high costs associated with the deformation and maintenance of liners caused by the use of water-stopping packings. Our temporary closure waterproof sheet method addresses these issues, contributing to the efficiency and cost reduction of bridge reinforcement work. 【Usage Scenarios】 - Temporary closures in bridge reinforcement work - Reinforcement of movable dam pillars - Areas requiring adjustments to water levels and flow rates 【Benefits of Implementation】 - Elimination of the need for water-stopping packings, simplifying assembly work - Enables the reuse of liner plates, contributing to cost reduction and reduced environmental impact - Maintains water-stopping capability even if movement occurs in the temporary closure frame - Reduces the load acting on the door body

basic information

【Features】 - By adopting a waterproof sheet, the process of incorporating a water-stopping packing during liner assembly has been eliminated, simplifying the assembly work. - In existing methods, the use of water-stopping packing led to deformation of the liner and high costs for maintenance, resulting in the disposal of temporary sealing materials; however, the adoption of a waterproof sheet allows for the reuse of liner plates. - The use of a waterproof sheet enables waste reduction and environmentally conscious construction. - When attaching a temporary sealing frame to the door body, no fixing such as welding is required. - The load acting on the door body can be minimized. 【Our Strengths】 We are a company engaged in construction consulting and general civil engineering. We handle temporary sealing waterproof sheet methods, temporary sealing FPS methods, special excavation pump dredging methods, and underwater surveys and measurements. We create technology to meet our customers' needs.
