Multi-wire-harness anchor cable equal-force tensioning equipment and equal-force tensioning method
The invention relates to multi-wire-harness anchor cable equal-force tensioning equipment and an equal-force tensioning method.The multi-wire-harness anchor cable equal-force tensioning equipment is used for tensioning a plurality of anchor cables and comprises an anchor cable continuous series connection continuous pre-tightening assembly, a tensioning assembly and a locking assembly; the multiple anchor cables are straightened through the anchor cable continuous series connection continuous pre-tightening assembly, a locking structure of the locking assembly keeps locked, the anchor cable continuous series connection continuous pre-tightening assembly is tensioned through the tensioning assembly, the anchor cable continuous series connection continuous pre-tightening assembly and the multiple anchor cables are integrated, and the purpose of tensioning the multiple anchor cables at a time is achieved through the tensioning assembly. And the magnitude and the direction of the applied prestress are kept consistent, so that effective equal-force tensioning is realized. The problems that in the prior art, a small jack is adopted for pre-tightening firstly, then one cross-core oil cylinder is used for tensioning a multi-wire-harness anchor cable on the whole, excessive tension missing or overtension exists in individual anchor cables, and the bearing capacity of the anchor cables is affected are effectively solved.
本申请涉及一种多线束锚索等力张拉装备及等力张拉方法，其中，多线束锚索等力张拉装备，用于多根锚索张拉，多线束锚索等力张拉装备包括：锚索连续串联连续预紧组件、张拉组件和锁定组件，锚索连续串联连续预紧组件使得多个锚索被拉直，锁定组件的锁紧结构保持锁紧，张拉组件对锚索连续串联连续预紧组件进行张拉，锚索连续串联连续预紧组件与多根锚索为一体，张拉组件实现一次张拉多根锚索的目的，并且预应力施加的大小和方向也保持一致，实现了有效地等力张拉。本申请有效地解决了现有技术中先采用小千斤顶预紧，然后再整体使用一个穿心油缸进行多线束锚索的张拉，个别锚索存在过度漏张或者超张的情况，影响锚索的承载力的问题。
