AI Technical Summary

Technical Problem

Existing pumpable well-filled frame bags are prone to lateral expansion or bulging when carrying compressed loads, resulting in insufficient load capacity, may rupture or premature failure, and unstable load behavior.

Method used

A pumpable well-filled frame bag assembly is designed including a housing bag and a reinforcement member. The receiving bag is composed of polyvinyl chloride laminated polyester, the side walls have inner and outer wall surfaces that define a total surface area, and the reinforcement member extends along the side walls, including a flat main surface to contact the side walls for restraining the bearing material.

Benefits of technology

By strengthening the design of the components, it can effectively constrain the load-bearing material, improve the load-bearing capacity, reduce the trend of lateral expansion and bulging, ensure that the support has stable load behavior under compressive load and extends its service life.
