Cast-in-place box girder prestress intelligent tensioning construction technology
The invention relates to a cast-in-place box girder prestress intelligent tensioning construction technology, and belongs to the field of prestress tensioning. The technology mainly comprises the following steps that S1, a steel strand is arranged in a penetrating mode; s2, a steel strand is sleeved with a working anchor, the multiple clamping pieces on one tensioning position are simultaneously inserted into and abut against the hole positions of the working anchor through a quick mounting mechanism, the steel strand is sleeved with a jack, then the steel strand is sleeved with a tool anchor, and then the multiple clamping pieces are simultaneously inserted into and abut against the hole positions of the tool anchor through the quick mounting mechanism; s3, a jack is controlled through the numerical control hydraulic pump station to stretch and draw the steel strand; s4, disassembling the tool anchor and the jack; and S5, grouting is conducted on the tensioning position hole channel through a grouting pump, and anchor sealing is conducted on the two ends of the tensioning position hole channel. And rapid installation and rapid abutting of the multiple clamping pieces are achieved through the rapid installation mechanism, and the construction efficiency of prestress tensioning on the box girder is effectively improved.
本申请涉及一种现浇箱梁预应力智能张拉施工工艺，属于预应力张拉的领域，主要包括以下步骤：S1：穿设钢绞线；S2：将工作锚套至钢绞线上，通过快装机构将一个张拉位上的多个夹片同时插入并抵紧至工作锚的孔位内，将千斤顶套至钢绞线上，再将工具锚套至钢绞线上，再次通过快装机构将多个夹片同时插入并抵紧至工具锚的孔位内；S3：通过数控液压泵站控制千斤顶对钢绞线进行张拉；S4：拆卸工具锚和千斤顶；S5：通过压浆泵对张拉位孔道进行压浆，对张拉位孔道两端进行封锚。通过快装机构实现多个夹片的快速安装以及快速抵紧，有效提升对箱梁进行预应力张拉的施工效率。
