Pressure-sustaining soil slope anchor and its construction method

Abstract

The invention discloses a pressure bearing type soil slope anchor and a construction method of the pressure bearing type soil slope anchor. According to the pressure bearing type soil slope anchor and the construction method of the pressure bearing type soil slope anchor, each soil slope is provided with a river embankment or a road embankment or a deep foundation pit, and plum-blossom-shaped anchor points are arranged on the soil slope. An anchor backing plate is arranged at each anchor point, wherein an anchor hole, perpendicular to the surface of the soil slope, is drilled in the soil slope through a central hole of the anchor backing plate, an elastic anchor rod is arranged in each anchor backing plate and each anchor hole, and an anchor pressure plate and a nut are arranged on the portion, which is exposed outside, of the elastic anchor rod; after the nut is screwed, the anchor pressure plate is enabled to abut against the surface of the soil slope, and then the elastic anchor rod is pulled outwards until inverted hooks of an inverted hook anchor head of the elastic anchor rod are inserted into soil at the bottom of the anchor hole and anchored; and then the anchor pressure plate is pressed in a flat mode and abuts against the anchor backing plate, and an elastic tube of the elastic anchor rod is stretched long for deformation. Due to the retraction force of the elastic tubes of the elastic anchor rods, soil particles of the soil slopes are enabled to remain in an under-pressure state and do not loose, the pressure bearing type soil slope anchor plays a role of supporting and fixing the soil slopes, and the overall stability of the soil slopes is improved. The pressure bearing type soil slope anchor and the construction method of the pressure bearing type soil slope anchor have the advantages of being suitable for soil slopes with different soil properties, simple and convenient to construct, low in manufacturing cost, capable of being used repeatedly, long in service life and the like, and are a novel soil slope reinforcing anchor and a novel construction method.

Description

technical field [0001] The invention relates to a pressure-sustaining anchor for soil slopes and a construction method thereof, in particular to a pressure-sustaining soil slope anchor and a construction method thereof. Background technique [0002] At present, soil slopes are often protected by methods such as soil nailing walls, pole-hanging net spraying, and stone masonry. Because these methods use steel bars, cement concrete and other materials to form rigid structures to support and fix soil slopes, and soil slopes are granular The soil particles are composed of loose bodies. Once subjected to water pressure, earth pressure, upper load, rainwater, frost heaving, etc., the soil of the slope will still loosen, collapse, and deform. These rigid slope protection structures cannot coordinate with the soil. The deformation and reinforcement of the soil slope often affects the overall stability of the soil slope. Contents of the invention [0003] Aiming at the deficiencies...
