| 中文摘要: |
| 本文介绍了采用库侧竖向可移动平台代替脚手架进行预应力钢绞线张拉的施工工艺，通过一系列工程验证，形成了安全可靠的预应力筒仓高空张拉系统。与搭设脚手架比较采用该装置节省施工费用90%，工程缩短35%。 |
| 英文摘要: |
| This paper introduces the construction technology of prestressed steel strand tensioning by using the vertical movable platform on the side of the silo instead of the scaffold. Through a series of engineering verification, a safe and reliable high-altitude tensioning system of prestressed silo is formed. Compared with erecting scaffold, using this device can save construction cost by 90% and shorten the project by 35%. |
