Abstract

The invention relates to a lead hole implanted anti-floating rock anchor rod with supporting trays. The lead hole implanted anti-floating rock anchor rod is characterized by mainly consisting of an anchor rod, supporting tray steel bar frameworks, a chassis, a backing plate and an anchor head, wherein an anchoring section of the anchor rod is arranged in a rock stratum pore passage with the supporting trays; the rock stratum pore passage is filled with a steel bar anchoring agent; the steel bar anchoring agent is wrapped with a geotextile bag; a free section of the anchor rod is arranged in a foundation bottom plate, is wrapped with a drivepipe and is isolated from concretes of the bottom plate; the supporting tray steel bar frameworks are fixed to the anchor rod in a manner of corresponding to the heights of the supporting trays in the rock stratum pore passage. The reaming supporting trays are arranged in the rock stratum pore passage, and the expandibility and adhesiveness of the steel bar anchoring agent are utilized, so that the anchoring force in unit length of the anchor rod is improved, the anti-floating capability of the anchor rod can be increased, the length of the anchor rod and the drilling depth of a rock stratum can be relatively shortened, and the lead hole implanted anti-floating rock anchor rod has favorable technical and economical benefits. The invention also discloses a construction method of the anti-floating rock anchor rod.

Description

technical field [0001] The invention relates to an anti-pumice anchor rod with a support plate and a construction method for a guide hole implantation, in particular to a prestressed anchor rod with a support plate embedded in a rock stratum with an outer package of geotechnical cloth bags. The utility model belongs to the technical field of anti-floating construction of underground structures of buildings, and is especially suitable for anti-floating construction of structures with exposed rock formations or shallow buried depths at the bottom of underground structures, and can also be used for surrounding rock or side slope reinforcement projects. Background technique [0002] In order to fully develop and utilize the underground space, the use of buried underground structures as garages and other functions is gradually increasing. Among them, the pure basement part, podium or relatively independent underground structure of a square-style building has a large construction ...
