Anchoring structure with pre-stressed anchor rods arranged in staggered twisting mode
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.
本发明涉及锚固结构的技术领域，公开了预应力锚杆错搓式布置的锚固结构，包括锚孔、多个锚筋以及锚具，锚筋具有内部段以及外部段；内部段包括有粘结段以及自由段；锚孔内填充有浆体，浆体包裹着粘结段以及自由段，浆体分别与地层以及粘结段粘结固定，自由段的外部套设有隔离层，隔离层与浆体粘结固定；多个锚筋上的隔离层的长度相异，呈错搓状布置；通过在锚筋的自由段套设隔离层，多个锚筋上的隔离层的长度呈错搓状布置，各个锚筋的自由段的长度也不同，在进行张拉锚固时，只需要采用一个千斤顶对多个锚筋同时进行锚固，不会产生明显的拉力差或变形差，张拉锚固后的锚杆可以获得拉力分散型锚杆一样的较高承载力。
