新疆阿勒泰地区属高寒地区,预应力构件生产与管理有其特殊性。现介绍解决因温差导致预应力构件断面贯穿裂缝的两种方法。一、墩式预应力长线台座滑移法1.在原长线台面刷隔离剂,待隔离剂干后,利用直径5mm废旧冷拔钢丝焊接或绑扎,长度为104m,按30～40 mm间距排列,张拉应力为5.7～
Altay region of Xinjiang is a cold area, the production and management of prestressed components has its own particularity. Now introduced to solve the temperature difference caused by pre-stressing member section through the cracks in two ways. First, pier-type prestressed long-term pedestal slip method 1. In the original long-term desktop brush release agent, to be isolated dry agent, the use of diameter 5mm scrap cold-drawn steel wire welding or banding, length of 104m, arranged by 30 ~ 40mm spacing, Zhang Tensile stress is 5.7 ~
