AI Technical Summary

Technical Problem

Existing emergency flood control facilities are inadequate in terms of deployment efficiency, structural stability, impact resistance, and seepage prevention, making them difficult to deploy and use effectively under extreme flood conditions.

Method used

The system employs an arched, foldable horizontal retaining wall, an internal counterweight system, a longitudinal support system, and an anti-seepage anchoring system, combined with magnetic quick-assembly and a composite anti-seepage layer, to form a highly efficient flood control facility.

Benefits of technology

It achieves rapid deployment (30-meter defense line completed within 15 minutes), high structural stability, water pressure resistance and seepage prevention performance, reduces overall costs and increases the number of times the facility can be reused.

Abstract

This invention belongs to the field of emergency flood control engineering technology, specifically relating to a foldable and rapid flood barrier structure and its construction method. It includes: at least one transverse foldable retaining wall unit; a counterweight system disposed inside or at the bottom of the transverse foldable retaining wall unit; a longitudinal support system including at least one support member, one end of which is connected to the backwater surface of the transverse foldable retaining wall unit, and the other end for connection to the ground foundation; and a seepage prevention and anchoring system including a seepage prevention layer laid on the ground foundation and anchors for anchoring the longitudinal support system to the ground foundation. This invention, by employing an arched transverse foldable retaining wall, utilizes the mechanical properties of the arch to efficiently transfer water pressure to the support systems on both sides, significantly improving the water pressure resistance and impact resistance of the retaining structure.
