Slope anti-slip system

Abstract

The invention discloses a slope anti-slip system. The slope anti-slip system is used for realizing anti-slip and fixing functions on slope roof greening structures, edge slopes and the like. The slope anti-slip system comprises an anchor rope, anchoring units and an edge slope fixing layer, wherein the edge slope fixing layer is distributed along an edge slope; the anchoring units are arranged along the longitudinal direction of the edge slope fixing layer; the anchor rope is connected with the adjacent anchoring unit; each anchoring unit comprises an anchor rod, an outer sleeve pipe and a rotary tightening part, each outer sleeve pipe is sheathed on the corresponding anchor rod and is embedded into the edge slope, and each rotary tightening part is in matching connection with the upper end of the corresponding anchor rod and is used for jacking the upper end surface of the outer sleeve pipe; the lower end of each anchor rod is provided with a lower slide head, a lower rolling passage is formed between the inner wall of each outer sleeve cylinder and the outer wall of the corresponding lower slide head, and a lower rolling element is arranged in each lower rolling passage and is moved along with the corresponding anchor rod; each lower rolling passage is provided with a limiting upper part, and when each anchor rod is moved up, each limiting upper part is reduced to limit the moving of the corresponding lower rolling element and lower slide head; each outer sleeve pipe forms a support bottom surface under the corresponding lower rolling passage, and a lower elastic part is arranged on the corresponding support bottom surface. The slope anti-slip system has the advantages that the elastic restoration capacity is realized, the soil fixing and anti-slip effects are good, and the installation is firm and stable.

Description

technical field [0001] The invention relates to the field of slope anti-slip technology, in particular to a slope anti-slip system, which is used for anti-slip and fixation on slope roof greening structures, side slopes and other occasions where relative movement between layers is easy to occur. Background technique [0002] When the slope formed in the engineering construction encounters rainy days or strong vibrations, geological disasters such as landslides, collapses, swelling or spalling often occur. In order to prevent the occurrence of the above-mentioned geological disasters, slope treatment is required. Among them, Anti-slide piles or prestressed cables, or the combination of anti-slide piles and prestressed cables, are commonly used support structures for slope treatment. According to the geological composition, the slope can be divided into landslide body and sliding bed from outside to inside. The landslide body is also called the unstable area. Relatively, the s...

Problems solved by technology

[0005] The anti-slide pile with the above structure has the following disadvantages: (1) The lower tapered expansion head and the lower expansion part are rigidly squeezed. When the anchor rod moves under the action of external force, it will drive the outer casing to move, and the moved position cannot be restored, reducing the The use effect of anti-slide pile

(2) The frictional resistance between the lower tapered expansion head and the lower expansion part is large, and the lower expansion part forms at least three incision shapes, where the position is prone to breakage and damage, and the service life is short

(2) The structure of the damping and shock-absorbing component is complex, and it can only be used for shock-absorbing the installation head of the anchor cable, and cannot shock-absorb the entire anti-slide pile, and its application range is limited

(3) The damping and vibration-absorbing components have high requirements on the environment, while the anti-slide piles are small in size and require high
