Anchor ring prestress construction process
The invention discloses a ring anchor prestress construction technology, and belongs to the technical field of constructional engineering. The method comprises the following steps: cleaning the corrugated pipe; the blanked steel strands are bundled in a layered mode and then bundled in a whole bundle, and cable penetrating is conducted; tensioning is conducted through the processes of stranded wire pre-tightening, whole bundle tensioning sequencing and same-sequence load grading; when the preset tension strength is reached, pre-burying a duct grouting pipe and grouting; the duct grouting pipe is positioned at the bottom of the corrugated pipe; and backfilling the anchor groove at the anchoring end. That is to say, layered binding treatment is carried out before the whole bundle of steel strands is bound, the situation that due to the fact that the steel strands intersect and are subjected to uneven tensioning force in the tensioning process, the steel strands are broken, and then the structural durability is not high is avoided, and the structural durability is improved.
本申请公开了一种环锚预应力施工工艺，属于建筑工程技术领域。该方法包括清洗波纹管；将下料后的钢绞线分层捆扎后再进行整束绑扎，并进行穿索；采用绞线预紧，整束张拉分序，同序荷载分级的工艺进行张拉；当达到预设张拉强度后，预埋孔道压浆管并进行压浆；所述孔道压浆管位于所述波纹管底部；对锚固端锚槽进行回填。也就是说，基于本申请在将钢绞线整束捆扎之前进行了分层捆扎处理，避免了因钢绞线交叉，在张拉时受到的张拉力不均，导致钢绞线断裂，进而导致结构耐久性不高，本申请提高了结构的耐久性。
