Abstract

The invention provides a mechanical recovery device and application method of an umbrella anchor. The recovery device includes an anchor head fixing device, a connecting rope and a top recovery device. The anchor head fixing device includes a screw with holes and an anchor fixed to the umbrella anchor. The pulleys on both sides of the main rod of the head, one end of the two anchor plates are connected to the main rod of the anchor head in rotation, the top recovery device includes a hoist and a supporting fixed bracket, and the hoist is fixed on the supporting fixed bracket; one end of the connecting rope is fixed to the umbrella by a screw with a hole On the anchor plate of the type anchor, the other end of the connecting rope is connected to the hoist of the top recovery device along the anchor rod through the pulley fixed to the main rod of the anchor head. In the present invention, by adding connecting ropes and pulleys, using screws with holes to fix the connecting ropes on the anchor plate, and using a hoist to pull the anchor plate to keep the closed state during the pull-up process, resisting the soil resistance during the dragging process, and realizing the umbrella shape The effective recycling of the anchor, the whole recycling process is very simple, the construction speed is fast and the efficiency is high.

Description

technical field [0001] The invention relates to the technical field of rock and soil reinforcement, in particular to a mechanical recovery device and an application method of an umbrella anchor. Background technique [0002] The non-grouting anchoring method is an emergency reinforcement measure for geotechnical structures developed in recent years. It mainly uses the resistance of the soil itself to provide the anchoring force required for reinforcement. It can play a role after the construction is completed and can effectively meet the emergency reinforcement requirements. For example, a glass fiber reinforced plastic spiral anchor and its application method invented by Zou Weilie et al. (CN201110427770.0), a special emergency driven umbrella anchor and its application method invented by Cheng Zhanlin et al. (ZL201510413982.1), etc. Among them, the umbrella anchor is an anchoring method proposed in recent years, which mainly uses the anchor head to provide the required anc...
