摘要
采用智能张拉和智能压浆施工技术,实现张拉过程智能控制,消除人工操作误差,具有精确、同步、自动控制张拉应力、延伸量、加载速率、停顿点、持荷时间等要素的特点,改变了传统的张拉压浆工艺,严格控制预应力张拉的精度和管道压浆的密实度,实现预应力张拉施工全过程质量管理。
The article uses intelligent tensioning and intelligent grouting construction technology to achieve the intelligent control of the tension process and eliminate manual operation errors. It has the characteristics of precise, synchronous, automatic control of tensile stress, elongation, loading rate, stopping point, holding time and so on, the precision of prestressed tension and the compactness of pipeline grouting are strictly controlled to realize the quality management of the whole process of prestressed tension construction.
