Problems solved by technology

At present, FRP anchors are proposed for such permanent anchors, which use the anti-rust properties of fibers and epoxy to solve the durability problem. At the same time, use grouting in the soil layer and grouting bags of various materials Anchor the anchor rod to improve the anchoring force of the anchor rod in the soil; however, these construction technologies have not yet formed a serialized anchor rod and anchor rod construction technology, and the processes of anchor rod body, anchor bag, drilling and other processes cannot be unified, which affects The construction progress and construction quality lead to poor anchoring effect and low efficiency, and the popularization and application are hindered

Abstract

An FRP sprinkling irrigation combined anchor bolt comprises an FRP hollow anchor bolt body. The upper end of the FRP hollow anchor bolt body is provided with an anchoring head used for anchoring the FRP hollow anchor bolt body, the combined anchor bolt further comprises a drill bit used for drilling an anchor bolt hole, and the drill bit is detachably installed at the lower end of the FRP hollow anchor bolt body. The invention provides a sprinkling irrigation combined anchor bolt which is convenient to use.

Description

technical field [0001] The invention belongs to the technical field of rock-soil anchorage, and in particular relates to an FRP sprinkler irrigation combined anchor rod. Background technique [0002] In the field of civil engineering, the use of bolts has a long history, but most of the bolts are used in rock mass, and are mainly used for temporary support of mining engineering and rock tunnels. Due to the short working time of temporary support, anchor Most of the rods use metal anchor rods as the basic material, and the anchoring methods mostly use the firmness of the rock mass to consolidate the anchor rod body and the rock mass. There are mainly hole bottom anchors and full-length bonded anchorage methods. With the rapid development of expressways in my country and the popularization of urban high-rise buildings, the principle of anchor rods has been introduced into these projects, and has been widely used in soil slope stability and high-rise building basement anti-floa...
