AI Technical Summary

Technical Problem

Traditional protective measures are effective in preventing piping in dikes in the short term but are prone to clogging and failure. Rigid drainage systems are prone to stress concentration in dynamic water flow, leading to local fatigue failure and threatening the stability of the dike.

Method used

Multiple square airbags are used, which can be quickly assembled through connecting and fixing components. Combined with double-layer composite materials and counterweight components, a modular protective structure is formed. The airbags are equipped with inflation joints to support rapid inflation and deflation, and the counterweight components enhance stability and erosion resistance.

Benefits of technology

It enables rapid deployment and flexible adaptation to different dam shapes, enhances resistance to water flow impact and sealing performance, extends service life, and reduces construction and maintenance costs.

Abstract

The invention discloses an anti-piping device which has the following advantages that (1) modular design is adopted, specifically, a square air bag cushion is quickly spliced through a connecting assembly and a fixing assembly, and the square air bag cushion is flexible, adapts to different dam shapes and is flexible in construction; (2) dual counterweight stability: the first counterweight assembly tightly presses the junction of the adjacent airbag cushions, the second counterweight assembly enhances the bottom anti-scouring capability, and the overall water flow impact resistance is high; (3) structure optimization: the square air bag parts are arranged, distributed and communicated, pressure is dispersed, and local stress concentration is avoided; the double-layer composite material (the braided fabric outer layer and the rubber inner layer) has both strength and tear resistance, and the service life is prolonged; and (4) rapid deployment: an inflation joint supports rapid inflation and deflation, and transportation and emergency response are facilitated.
