Problems solved by technology
[0003] In the prior art, although the support structure of anti-slide piles and prestressed beams has good bending and shearing resistance, it is inconvenient to install and the process is relatively complicated. The anchoring needs to be fixed by concrete, which not only costs a lot, but also requires labor intensity. High, and the self-adaptive effect after installation is not good, especially the expansion effect on the slope is limited

The invention discloses an anti-sliding pile for slope support. The anti-sliding pile comprises an anchoring rod, an outer bushing sleeved on the anchoring rod for being buried in the slope deeply and a screwing part which is in threaded fit with the upper end of the anchor rod and abuts against the upper end of the upper bushing. A lower taper expansion head expanding towards the end is arranged at the lower end of the anchoring rod, and at least three longitudinal notches are formed in the section of the outer bushing corresponding to the lower taper expansion head to form a lower expansion portion. The anchoring rod is sleeved in the outer bushing to form an overall anti-sliding pile structure, and accordingly, high anti-bending and anti-shearing capacities are provided, and the anti-sliding capacity is improved; besides, the lower taper expansion head at the tail end of the anchoring rod and the lower expansion portion form a self-lock structure, so that the anti-sliding pile is convenient and quick to mount, provided with a good fixing effect after being mounted, not prone to axial moving and capable of bearing high axial components produced by axial pulling force or slip mass slope staggering produced by slope expansion.
Description
technical field [0001] The invention relates to the field of slope treatment, in particular to an anti-slide pile for slope support. 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 sliding bed is called the stable area. Anti-slide piles or prestressed cables pass through The landslide body goes deep into the slide bed, which is used to support...
