Slope treatment method

Abstract

The invention discloses a slope treatment method. The slope treatment method comprises the steps that firstly, a retaining wall is constructed at the slope toe without disturbance, and soil is backfilled behind the wall for pressing feet; a plurality of rows and columns of grouting plates are poured on a slope; a plurality of disordered holes are formed in an outer pipe of a self-propelled anchor rod, grouting holes are drilled by the self-propelled anchor rod with the disordered holes, cement paste is poured by using an anchor rod grouting machine, grouting is carried out according to the grouting pressure required by the design, when the consistency of the slurry flowing out of the edge of a slurry stop plug is consistent with the injection consistency or a pressure gauge reaches a designed pressure value, grouting is stopped, and the cement paste penetrates through the disordered holes to form tree root-shaped cement stones; and an intercepting ditch is constructed at the slope top of the slope, a packway drainage ditch is constructed on a packway, vegetation is planted behind the retaining wall, and the whole construction is completed. The self-propelled anchor rod with the disordered holes is used, the construction disturbance is small, the construction is rapid and convenient, the tree root-shaped cement stones are formed through grouting, the slope is stabilized through the anti-skid performance of the slope toe anti-skid wall soil body, the earth excavation is reduced, excessive disturbance to the original landform is avoided, and the ecological environment is fully protected.

Description

technical field [0001] The invention relates to side slope treatment, which is a side slope treatment method. Background technique [0002] A slope is a slope with an inclined air surface, which has a tendency to slide downwards under the action of its own weight and external force. If the sliding force of a certain method surface in the slope is greater than or equal to the anti-sliding force of the slope body, it will cause The slope is unstable. [0003] Anchor is a commonly used form of slope reinforcement. The self-advancing anchor combines drilling, anchor installation, grouting, and anchoring into one. The grout is sprayed from the borehole through the hollow of the anchor, which can quickly fill the cracks around the anchor. , has the advantages of fast construction speed, strong anchoring force and simple operation. Press the cement mortar into the pipe through grouting, and the mortar will turn out of the steel pipe through the overflow hole on the anchor rod or ...

AI Technical Summary

Problems solved by technology

[0004] Traditional slope treatment often adopts anchor rods (anchor cables) + frame beams, shotcrete, anti-slide piles (walls), and stone masonry slope protection. These measures greatly disturb the original slope and greatly damage the slope vegetation. , without ecological environmental protection and landscape functions
