Protective device for unsaturated red clay side slope

Abstract

The invention provides a protective device for an unsaturated red clay side slope. The protective device is reasonable in structure, fast in construction and excellent in anti-slide performance and comprises an anti-slide pile and an anchor rod, wherein the anti-slide pile and the anchor rod are fixedly connected and form an acute angle; the anti-slide pile comprises a central pile, a sleeve and an end socket; the sleeve is arranged on the outer wall of the central pile in a sleeving manner; the head end of the central pile stretches out of the sleeve and is provided with a groove matched withthe anchor rod; a plurality of longitudinal notches are arranged on the outer wall of the pipe section, corresponding to the tail end of the central pile, of the sleeve to form a sleeve tightening end; the end part internal diameter of the sleeve tightening end is smaller than the external diameter of the central pile; a cavity is formed in the anchor rod; a tensile component is arranged in the cavity; and a plurality of through holes for communicating the cavity with the external part of the anchor rod and enabling the tensile component to stretch out of the cavity are formed in the outer wall of the anchor rod. According to the protective device, the anti-slide pile and the anchor rod are cooperated to enhance the anti-slide performance of the protective device; and the protective device is higher than other passive type side slope protective devices in the aspects of tensile performance and pulling-resistance performance and is particularly suitable for protection of the unsaturated red clay side slope.

Description

technical field [0001] The invention relates to a slope protection device, in particular to a protection device for an unsaturated red clay slope, and belongs to the field of landslide and slope engineering treatment. Background technique [0002] Red clay refers to carbonate rocks (limestone, dolomite, argillaceous mudstone, etc.), which are brownish-red, brown-red or yellow in residual deposits, slope deposits or residual-slope deposits weathered under subtropical warm and humid climate conditions. Brown high-plasticity clay with a high degree of weathering and strong changes in mineral and chemical composition. The mineral composition of red clay is mainly kaolinite and quartz with weak hydrophilicity, low mobility and iron cementation. Because of its characteristics of dehydration shrinkage, crack development, and hard top and soft bottom, this soil type is mostly barren grassland with sparse vegetation, serious soil erosion, and prone to drought due to water shortage. ...
