Abstract

The invention discloses a tensile support type anti-floating anchor structure. The tensile support type anti-floating anchor structure is used for solving the problem that the anchoring strength to a rock-soil body of an existing anchor structure is poor. The tensile support type anti-floating anchor structure comprises an anchor rod, a grouting body and an anchor eye formed in the rock-soil body, wherein one end of the anchor rod stretches into the anchor eye, the grouting body is arranged in the anchor eye and integrally adheres to the rock-soil body, the diameter of the lower end of the anchor eye is larger than that of the upper end of the anchor eye, the anchor rod comprises a fixing support, at least one anchor rod steel bar is arranged on the outer circumference of the fixing support, and a binding support is arranged on the periphery of each anchor rod steel bar in a sleeved mode. According to the tensile support type anti-floating anchor structure, by changing the structure of a traditional anchor eye and the structure of a traditional anchor rod, the contact area between the anchor rod structure and the rock-soil body is enlarged, and the anchoring strength to the rock-soil body of the anchor rod structure is increased; the anchoring strength to the rock-soil body of the anchor rod structure is increased without the need of lengthening the anchor rod, the length of the anchor rod is reduced, and manufacturing cost is reduced.

Description

technical field [0001] The invention belongs to the field of engineering support, and in particular relates to a tensile support type anti-floating anchor rod structure, which is used for reinforcing and stabilizing rock and soil bodies and preventing rock and soil bodies from collapsing or deforming. Background technique [0002] At present, in the field of engineering support, the stability of the working face is a very important technical link, which directly affects the safety of life and property. Due to the movement of part of the rock and soil mass, the entire rock and soil mass loses its ability to withstand pressure. [0003] Usually, in order to stabilize the rock and soil mass, it is necessary to drill holes in the working face, use synthetic material injection pipes as anchor bolts to reinforce the holes, and then fill the holes with cement mortar as adhesives and fixing elements. [0004] as attached figure 1 In the prior art anchor structure, the existing anc...
