Combined rock-embedded anchor cable slide-resistant pile where round steel is implanted and construction method thereof

Abstract

The invention discloses a combined rock-embedded anchor cable slide-resistant pile where round steel is implanted and a construction method of the combined rock-embedded anchor cable slide-resistant pile. Under the combined action of a slide-resistant pile body, the multiple bars of rock-embedded round steel, an inclined anchor cable, a top beam and rock-soil bodies on the periphery, the combined rock-embedded anchor cable slide-resistant pile is formed. The rock-embedded round steel is used for integrating the reinforced concrete structure of the load-bearing section and the rock-embedded section of the slide-resistant pile in a mode of the rock-embedded round steel and limestone bodies, so that stress coordination and uniformity are achieved. The mode that the rock-embedded round steel is implanted into the limestone is adopted for rock embedding, so that the slide-resistant pile is sufficient in rock-embedded anchoring length and shearing strength, and it is unnecessary that explosion is used for removing the limestone. The strength of the limestone is sufficiently utilized, and the combined action with the limestone is achieved; the technology is simple, the construction period is short, and the time advantage is obvious in emergency treatment of a landslide; in a bed rock fracture development region, fractures are filled with poured cement paste, and therefore the strength of bed rock bodies is improved. According to the method, in the risky landslide prevention and treatment engineering, especially in an underlying limestone region, the combined rock-embedded anchor cable slide-resistant pile has unique advantages and broad application prospects.

Description

technical field [0001] The invention relates to an anti-slide pile, in particular to a combined rock-socketed anchor cable anti-slide pile implanted with round steel, and the invention also relates to a construction method of the combined rock-socketed anchor cable anti-slide pile implanted with round steel . Background technique [0002] Landslide prevention research is a hot issue in geological engineering. Landslide is a serious geological phenomenon that often causes serious personal injury or property loss. At present, the anti-slide structures commonly used are mainly anti-slide piles, micro-pile groups, anti-slide retaining walls, prestressed anchor cables, etc., among which anti-slide piles are one of the most commonly used landslide control measures. The general anti-slide pile is a kind of reinforced concrete pile that passes through the landslide mass and anchors the stable stratum to a certain depth. The pile body resistance provided by the stable stratum embed...

Problems solved by technology

However, blasting has the following defects: (1) blasting vibration is easy to cause loosening of the rear edge (sliding) slope, which is detrimental to the overall stability of the side (sliding) slope; (2) blasting vibration may resist the embeddedness of sliding piles The limestone around the section will cause shock cracks, produce new cracks or enlarge the original cracks, and destroy the integrity of the limestone rock mass; (3) blasting will damage the integrity and stability of the artificial excavation pile wall protection, and often occurs The entire wall concrete collapsed due to blasting, resulting in scrapped pile holes; (4) The strength of limestone is high, and the blasting footage is slow and takes a long time, which affects the construction progress. The construction period is particularly tight, (although the static demolition has no vibration effect, it takes a long period of time to demolish the limestone); (5) The risk of blasting operations is high, especially when workers are drilling blastholes at the bottom of the hole, it is very dangerous and the bottom of the hole is very dangerous. The air quality is extremely poor, which affects the health of workers; (6) The cost of blasting is high, and the blasting procedures are strict and complicated, which takes a long time
