Embodiment

[0041] Such as Figure 1-2 As shown, the natural lattice reinforcement structure of a slope shallow surface layer loose body disclosed by the present invention includes multiple rows of parallel transverse grouting body groups and multiple rows of mutually parallel longitudinal grouting body groups, the transverse grouting body groups and The longitudinal grouting bodies are arranged crosswise to form a reinforced frame. Both the transverse grouting body group and the longitudinal grouting body group include at least one row of grouting bodies 3 arranged in sequence, and the grouting bodies 3 pass through the superficial loose body 2 and extend to the sliding bed 1 along a direction perpendicular to the slope.

[0042] In this reinforcement structure, grouting is adopted, and a reinforcement frame consisting of only a few grouting bodies 3 is set on the slope. Since only the pressure grouting is used to form the grouting body, the reinforcement of the shallow surface loose bo...

Abstract

The invention discloses a slope superficial loose body natural lattice reinforcing structure and reinforcing method, and relates to the technical field of geological disaster prevention and control. The slope superficial loose body natural lattice reinforcing structure and reinforcing method are mainly used for solving the problems that an existing slope lattice project is damaged due to the effect of surface water, and the environment is greatly damaged in the construction process. The slope superficial loose body natural lattice reinforcing structure comprises a plurality of rows of transverse grouting body sets and a plurality of rows of longitudinal grouting body sets, wherein the transverse grouting body sets and the longitudinal grouting body sets are arranged in a crossed mode to form a reinforcing frame; and the transverse grouting body sets and the longitudinal grouting body sets each comprise grouting bodies which are sequentially arranged, and the grouting bodies penetrate through superficial loose bodies and extend to a sliding bed. The slope superficial loose body natural lattice reinforcing structure and reinforcing method have the advantages of being good in reinforcing effect, convenient to construct and small in damage to the environment.

Description

technical field [0001] The invention relates to the technical field of prevention and control of geological disasters, in particular to a natural lattice reinforcement structure and reinforcement method for shallow surface loose body of a slope. Background technique [0002] my country's mountains and hills account for more than 2 / 3 of the total land area, and it is one of the countries where slope disasters occur most frequently in the world, especially in western regions such as Sichuan, Chongqing, Guizhou, and Yunnan. Unstable slopes with serious safety hazards. [0003] At present, slope control measures are generally divided into two types: one is load reduction measures, including reducing weight above the landslide, adding weight below the landslide, doing drainage works at the back of the landslide, and adding waterproof protective surfaces; the other is supporting Reinforcement measures include retaining walls, anti-slide piles, anchor cables and bolts, and shotcret...
