Abstract

The invention relates to the technical field of anchoring structures, and discloses an anchoring structure with pre-stressed anchor rods arranged in a staggered twisting mode, the anchoring structure comprises anchor holes, a plurality of anchor bars and anchorage devices, and each anchor bar is provided with an inner section and an outer section; the inner section comprises a bonding section and a free section; the anchor hole is filled with slurry, the slurry wraps the bonding section and the free section, the slurry is bonded and fixed to the stratum and the bonding section, the free section is sleeved with an isolation layer, and the isolation layer is bonded and fixed to the slurry; the isolating layers on the anchor bars are different in length and are arranged in a staggered twisting mode. The free sections of the anchor bars are sleeved with the isolation layers, the lengths of the isolation layers on the anchor bars are arranged in the staggered rubbing shape, the lengths of the free sections of the anchor bars are different, and therefore when tensioning and anchoring are conducted, only one jack is needed to conduct anchoring on the anchor bars at the same time, and obvious tension difference or deformation difference cannot be generated; the anchor rod which is tensioned and anchored can obtain the same high bearing capacity as that of a tension dispersing type anchor rod.

Description

technical field [0001] The patent of the present invention relates to the technical field of anchoring structures, in particular, to an anchoring structure with staggered arrangement of prestressed anchor rods. Background technique [0002] The anchoring structure of prestressed bolts is widely used in geotechnical engineering. The principle of the anchoring structure of ordinary tension-type prestressed anchors is as follows: the bolt consists of an anchor head, a free section and an anchoring section. The anchoring section is filled with slurry, and the slurry It is bonded to the ground around the anchor hole to provide anchoring force, and at the same time, it is also bonded to the bolt to prevent the bolt from being pulled out of the slurry. After the free segment is stressed, it deforms freely and does not provide anchoring force. The anchor head transfers the load (including the prestress and external load imposed by the jack tension) to the free segment and locks the ...
