Abstract

The invention discloses a rapid repairing structure for a shallow landslide of an above-second-level soil slope and a construction method thereof. According to the repairing structure, a step is excavated on a landslide part of a landslide body, multiple layers of backfill bagged soil are constructed on the step in a filling manner, and geogrids are laid at the bottom of each layer of backfill bagged soil; reserved parts of the geogrids are reversely wrapped along the backfill bagged soil on the upper portions of the geogrids and tensioned to the required tensile strength, the geogrids are fixed to the top face of the backfill bagged soil through U-shaped nails to form reverse wrapping, and the reverse wrapping geogrids and the geogrids adjacent to the upper layer are fixedly connected through U-shaped nails and are both fixed to the top face of the corresponding backfill bagged soil; and a plurality of steel bars are implanted into the bottom of a reinforced body formed by combining the backfill bagged soil and the geogrids. The repairing structure plays a supporting role, meanwhile, energy dissipation is achieved on expansion deformation generated by soil in the slope through self deformation, the repairing effect is good, construction is easy and convenient, the technical requirements for personnel are low, the construction period is short, the number of machines is small, risks are low, cost is low, and environment friendliness is achieved.

Description

Technical field [0001] The present invention belongs to the technical field of engineering, involving soil slope shallow slope in one second stage and more rapid repair structure construction method. Background technique [0002] Shallow landslide traditional processing methods typically employ a rigid support structure for cement stone retaining wall, this method needs to call a variety of construction machinery and a large number of co-workers. For two or more slide, due to the higher position, narrow construction site, a variety of construction machinery (such as excavators, rollers, etc.) can not be used, conventional processing method can only slide for Masonry manual excavation of soil, with a crane and landslide lifting the car to earth ground, transported to the spoil ground; then, the outsourcing of stone and concrete and then transported to landslides, with a crane on the stone and concrete, masonry manually on the slope repair of landslide, such as figure 1 Indicated. ...
