Abstract

The invention provides a self-locking anchoring fiber anchor rod and a construction method and belongs to the technical field of rock and soil anchoring. The self-locking anchoring fiber anchor rod is composed of a fiber bag, a base plate and a euphroe. The fiber bag is internally provided with a locating rack in a sleeving mode. The locating rack extends into the bottom of the fiber bag. The fiber bag is tightly clamped and fixed to the locating rack from the outer side of a cylinder through a metal clamp. According to the euphroe, a central tube is arranged in a support in a sleeved mode; ratchets are mounted on the left side and the right side of the central tube respectively and located at the outer side of the support; racks matched with the ratchets are hinged to the support through shaft pins; a rope hook is fixed to the central tube; a round hole is formed in one end of the central tube and located at the outer side of the support, and a thrust rod is inserted into the round hole. A grout body is grouted into the fiber bag through a sleeve valve under the action of pressure, the fiber bag expands, the grout body coagulates, solidifies and is anchored in a stable layer; the euphroe is fixed to the base plate through bolts, and the rope-form fiber bag is bundled to the rope hook of the euphroe. The self-locking anchoring fiber anchor rod is light in structure, anti-corrosive, high in durability and quick and convenient to construct and solves the problems of traditional FRP bar tensioning and anchoring, and prestress compensation is convenient.

Description

technical field

[0001] The invention belongs to the technical field of rock-soil anchoring engineering, and in particular relates to a self-locking anchoring fiber anchor rod and a construction method, which are mainly applicable to support projects such as slopes and foundation pits. Background technique

[0002] In the fields of underground engineering, foundation pit and slope engineering, bolt support is the most widely used geotechnical reinforcement measure. The anchor rod balances the sliding thrust of the rock and soil by anchoring itself into the rock and soil to bear the tensile force, thereby improving the self-stabilizing ability of the rock and soil. At present, the common types of anchors mainly include grouting anchors, anchor cables, mechanical anchors, pipe joint anchors, body expansion anchors, shell expansion anchors, etc. The material of these anchors is mainly steel, but steel The easy-to-corrosion problem of the anchorage system has increasingly become...
