AI Technical Summary

Technical Problem

The side water seal structure of the hydraulic steel dam gate has gaps, resulting in poor water-stopping effect. In particular, the bottom shaft end water seal cannot be pre-pressurized and the U-shaped side water seal cannot be connected as a whole, affecting the sealing performance.

Method used

The hydraulic steel dam gate is installed using hinged supports, and a continuous integral sealing structure is formed by combining the first water seal and the second water seal. The second water seal is arranged in an arc along the edge of the gate and is equipped with a pre-compression amount. The bottom shaft end cap is eliminated, and a seamless seal is formed by adhesive bonding.

Benefits of technology

It improves the sealing and water-stopping effect of the gate, reduces the impact of processing and assembly errors, and ensures good sealing performance of the gate when closed.
