AI Technical Summary

Technical Problem

Existing trench support structures have significant deficiencies in terms of ease of depth expansion, connection stability, support rationality, and component matching accuracy, resulting in low construction efficiency and safety hazards.

Method used

The design features double-rail parallel guides on the inner side of the columns. The support plates are connected to the guides via T-shaped ends. The top walers and bottom supports are fixed by specific connecting components. The middle support uses telescopic sleeve rods, which, combined with a hydraulic propulsion device, enable layer-by-layer installation and flexible support.

Benefits of technology

It improves the safety and stability of trench support, enhances construction efficiency, ensures the firmness of connections and the wear resistance of components, and extends service life.

Abstract

The utility model discloses a kind of trench hydraulic support structures, to solve the problems of existing trench support structure, such as inconvenient depth expansion, unstable connection, unreasonable support and poor component matching precision.The structure includes upright, support plate, top surrounding purlin, bottom support, and middle support can also be set according to requirement.Upright inside is trapezoidal section double-track parallel guide rail, support plate both ends have T-shaped end head engaged with it, gap fit between the two and T-shaped end head with wear layer.Support plate is modular steel plate, and depth expansion can be realized by layer-by-layer installation through hydraulic propulsion device.Top surrounding purlin is H-shaped steel beam, fixed on the top of upright by connecting assembly;Bottom support is H-shaped steel component, connected to the bottom of upright.Middle support is telescopic sleeve type rod, installed when excavation depth is greater than or equal to 2m.The structure is stable in connection, reasonable in support, high in component matching precision, and can improve the safety, stability and construction efficiency of trench support.
