新型钢绞线穿束机快速穿束综合施工技术

Integrated Technology of Rapid Strand Perforation by New Type Steel Strand Perforators

针对预制箱梁预应力孔道穿钢绞线的主要工具设备大多较为落后、工效低、费工费时的特点,人工下料慢、误差大、耗时长、编束、穿束工效低等问题,研制了体积小,操作简单,安装移动方便,数据精准的新型穿束设备;新型钢绞线穿束机快速穿束施工工序简单,集快速自动下料、快速自动编束、快速自动穿束一体化,避免了人工穿束的工作量,减少了人员投入,克服了人工放线的不安全性,下料误差大,耗时长等诸多难题,更是方便了施工、提高了工效、缩短了工期、节约了工程成本;该项技术具有适用于箱梁预应力穿束施工的明显优势。

As ordinary perforators are characterized by backwardness,low efficiency,consuming more work and time,slow speed of manual cutting,big errors involved when perforating steel strands for prefabricated box beam.New type perforators were developed,they are characterized by simple perforating process,little volumn,light weight,easy to operate and install,rapid automatic strand winding and rapid automatic perforating.Large work quantity is avoided,number of persons needed is reduced,the danger of manual cutting,big error of cutting and long time consuming are avoided.This technology has apparent advantages of perforating strands for box beam.
