Perfect for reinforcing movable weir pillars that can adjust water levels and flow rates for seismic reinforcement measures!

In the dam industry, the safety of structures and consideration for the environment are important. Aging-related leaks can lead to a decrease in dam functionality and impact the surrounding environment. Particularly in the reinforcement work of movable weir pillars, reliable water-stopping measures are required without applying excessive pressure on the movable gates. Our temporary closure waterproof sheet method eliminates the need for water-stopping packing and achieves water stopping through waterproof sheets. This ensures the safety of the dam and reduces environmental impact. [Usage Scenarios] - Reinforcement work for movable weir pillars - Leak prevention measures for dam embankments - Renovation work requiring temporary closures [Effects of Implementation] - Improved safety through reliable water-stopping performance - Shortened construction period and cost reduction by eliminating the need for water-stopping packing - Environmental consideration through the reuse of liner plates - Reduction of loads acting on the gate 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 has led to high costs for deformation and maintenance of the liner, resulting in the disposal of temporary sealing materials; however, the adoption of waterproof sheets allows for the reuse of liner plates. - The use of waterproof sheets enables waste reduction and environmentally conscious construction. - When installing temporary sealing frame ends on the door body, no fixing such as welding is necessary. - It can significantly reduce the load acting on the door body. 【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 propose the optimal methods tailored to our customers' needs.
