Packaged-type reinforced gabion retaining wall and construction method thereof

Abstract

The invention discloses a packaged-type reinforced gabion retaining wall and a construction method thereof. The retaining wall is formed by overlaying more than one packaged-type reinforced gabion structural unit connected with each other, wherein each unit comprises a gabion surface wall and a double-twisted polygonal metal mesh; the extending tail end of the double-twisted polygonal metal mesh is bent upwards to form a grooved gabion package mesh; and filling soil is tamped on a double-twisted hexagonal metal mesh. The construction method of the retaining wall comprises the following steps of: first, prefabricating a reinforced gabion plate and placing the reinforced gabion plate on a foundation; then, performing field assembly to obtain a preform; next, filling stone materials to obtain the gabion surface wall, paving geotextile on one side of the gabion surface wall, filling soil and tamping, simultaneously back bending the extending tail end of the metal mesh upwards to form the grooved gabion package mesh, and obtaining the packaged-type reinforced gabion structural unit; and finally, on the basis of the packaged-type reinforced gabion structural unit, repeating the construction steps from the bottom to the top until finishing construction. The retaining wall of the invention has the advantages of labor and material conservation, low cost, wide application range, high mechanical property and the like.

Description

technical field [0001] The invention relates to a retaining wall and a construction method thereof, in particular to a retaining wall provided with a gabion structure and a construction method thereof. Background technique [0002] Existing building retaining structures include flat-floor reinforced structures, reinforced gabion structures, and the like. The traditional flat-story reinforced structure is a soil retaining structure composed of beams, baffles, ribs and filling soil. Its mechanical characteristics are that the lateral pressure of the soil is transmitted to the beams through the baffles, and then transmitted from the beams to the ribs. Then the balance is maintained by the pull-out force of the ribs. This structure has the following defects: firstly, the surface of the retaining wall is not beautiful due to the existence of beams; secondly, long ribs must be installed, resulting in thicker horizontal and transverse fillers, which not only increases the work and...

AI Technical Summary

Problems solved by technology

This structure has the following defects: firstly, the surface of the retaining wall is not beautiful due to the existence of beams; secondly, long ribs must be set, resulting in thicker horizontal and transverse fillers, which not only increases the amount of work and materials, but also cannot be applied to some projects; finally , when the flat reinforced structure is high, the installation of prefabricated components needs to use lifting equipment, otherwise the components need to be poured on site

This structure has the following defects: (1) sand filler must be used, otherwise the pull-out resistance is not enough, and if viscous filler is used, the reinforcement needs to be very dense, which is not economical; (2) due to the friction between the reinforcement and the filler The force is stable, so the ribs must also be longer, which leads to thicker horizontal and horizontal fillers in the structure, increases the consumption of materials, and limits the scope of application.
