The invention provides a gantry-type anti-slide pile with a vertical prestressed anchor cable arranged on the inner pile. The gantry-type anti-slide pile includes: a pile body, an anchor cable device, a positioning anchor, a communication control device and a processor. The pile body includes a beam and two vertical beams connected as a whole; the anchor cable device partially passes through one of the vertical beams, and passes through the upper end of the pile body, and can pull the pile body to move on the upper side of the pile body; The positioning anchor is fixed at the lower end of the anchor cable device, and is pre-embedded in the lowermost rock formation to generate tension on the positioning anchor; the communication control device includes a controller and a winch, and the controller is electrically connected with the winch; The processor communicates, and the processor controls the start and stop of the hoist by sending control instructions to the controller; the anchor cable device includes: anchor cable and positioning pulley, the anchor cable penetrates the pile body and is integrated with the pile body by pre-embedding, the anchor cable The lower end is connected with the positioning anchor, the upper end is connected with the winch, and the anchor cable includes an upper anchor cable and a lower anchor cable.
Description
technical field [0001] The present invention generally relates to the technical field of anti-slide piles, and more particularly relates to a gantry type anti-slide pile in which vertical prestressed anchor cables are arranged on inner piles. Background technique [0002] Anti-slide piles are the main support measures for landslide control, which are divided into single-row piles and gantry piles (double-row piles). When the anti-sliding ability of the single-row piles cannot meet the requirements, the gantry piles are generally installed. The gantry anti-sliding pile is composed of an inner pile (on the side of the landslide), an outer pile and a connecting beam at the top of the pile. When the landslide thrust acts, the inner pile is under tension (pull resistance), and the outer pile is under compression, and the joint force is applied to stabilize the landslide. [0003] The inner piles of traditional gantry piles generally need to be embedded in stable rock formations...
