AI Technical Summary
Technical Problem
Existing rectangular composite formwork bags are prone to cracking at the joints when subjected to elastic deformation of concrete fillers, sun exposure, and rain corrosion, resulting in reduced service life and affecting the overall effect.
Method used
An extended thickened layer is provided at the connection between the rectangular and transverse molded bags, and a breathable groove is opened on the inner side of the inner molded layer to enhance the anti-rupture ability of the connection and the overall breathability.
Benefits of technology
It improves the tear resistance and overall strength of the geotextile bags, ensuring their stability and construction efficiency in complex terrains, and reducing engineering maintenance costs.

Abstract
This utility model discloses a rectangular composite formwork bag, relating to the field of filling technology. It includes a first rectangular formwork bag and a second rectangular formwork bag. A transverse formwork bag is fixedly installed on the opposite sides of the first and second rectangular formwork bags. An extended thickening layer is adhesively installed on the surface of the first rectangular formwork bag, and a limiting formwork bag edge is fixedly installed on the surface of the transverse formwork bag. This rectangular composite formwork bag, by providing an extended thickening layer at the connection between the first rectangular formwork bag and the transverse formwork bag, not only improves the anti-breakage effect of the first rectangular formwork bag itself through the extended thickening layer, but also limits and increases the resistance of the upper limiting formwork bag edge of the transverse formwork bag, thereby improving the anti-breakage effect at the connection between the transverse formwork bag and the first rectangular formwork bag. This ensures the service life of the first rectangular formwork bag and the transverse formwork bag, thus ensuring that the rectangular composite formwork bag has high strength, good overall performance, good overall flexibility during pouring, and can ensure that it adheres tightly to the ground after molding.
