Construction method of pressure dispersion type anchor cables
The invention provides a construction method of pressure dispersion type anchor cables. The construction method comprises the following steps that S1, a single steel strand in each bundle of pressuredispersion type anchor cable is pre-tightened, so that the stress of the single steel strand on the anchor cable is uniform; S2, grouping adjustment is conducted on the pre-tightened pressure dispersion type anchor cables; and S3, the pressure dispersion type anchor cables subjected to grouping adjustment are subjected to overall graded tensioning. According to the construction method, the supporting quality is ensured, the mounting precision is improved, and therefore the quality benefit of a project is improved.
本发明提供的一种压力分散型锚索的施工方法，包括以下步骤：步骤1，将每束压力分散型锚索中的单根钢绞线进行预紧，使得锚索上的单根钢绞线的应力均匀；步骤2，对进行预紧后的压力分散型锚索进行分组平差；步骤3，对分组平差后的压力分散型锚索进行整体分级张拉；本发明确保了支护的质量、提升了安装精度，从而提升了项目的质量效益。
