AI Technical Summary

Technical Problem

Existing airbag-type barrier devices have weak pressure resistance, are easily damaged, and have complex procedures. The steel pipes are poorly fitted to the trench walls and are difficult to remove, which reduces construction efficiency.

Method used

The geomembrane is vertically installed in the seepage prevention trench, and the barrier cylinders are set at the intersection of the backfill section and the excavation section. The barrier medium is injected and expands to form a stable barrier. The barrier cylinders and the geomembrane work together to simplify the installation and do not need to be removed.

Benefits of technology

Improve construction efficiency, enhance barrier stability and pressure resistance, prevent leakage from gaps, and extend service life.

Abstract

The application provides a high-efficiency blocking device and a high-efficiency anti-seepage body, wherein the high-efficiency blocking device comprises an anti-seepage film and two blocking barrels, the anti-seepage film is vertically arranged in an anti-seepage groove, and the two sides of the anti-seepage film are arranged at intervals from the anti-seepage groove; the two blocking barrels are arranged at the two sides of the anti-seepage film, the blocking barrels are arranged at the intersection of the backfill section and the excavation section of the anti-seepage groove, the top of the blocking barrel is provided with a feeding port, the blocking barrel has a contraction state of being flat and close to the two sides of the anti-seepage film, and the blocking barrel has an expansion state of being expanded by injecting a blocking medium to block the backfill section and the excavation section. The anti-seepage film is vertically arranged in the anti-seepage groove and is spaced from the groove wall, this arrangement not only provides precise and stable installation space for the two blocking barrels, but also enables the blocking barrels and the anti-seepage film to form a synergistic effect, so that the blocking structure and the anti-seepage body are not disconnected. The two blocking barrels are arranged at the two sides of the anti-seepage film and are located at the intersection of the backfill section and the excavation section, so that the positioning is precise and the blocking barrels can directly act on the key blocking area.
