确定预应力的张拉控制应力是桥梁预应力空心板预制施工的关键。所以在建设桥梁的社工工程中应该加强对预应力作用的使用,采用科学的方法措施,对施工中发现的问题及时地改正,为今后的桥梁工程建设积累经验。一、预应力施工方法在施工设计中应该注意对预应力中孔道的位置设计,根据实际的要求对孔道的位置进行合理地安排,并且做到对灌浆的严格要求。制作的孔应该管壁严密,这样可以使空洞不易
Determine the prestress tension control stress is the key precast bridge precast hollow slab construction. Therefore, the construction of bridges in social engineering should strengthen the role of prestressing, the use of scientific methods and measures to promptly correct the problems found in the construction for the future construction of the bridge engineering experience. First, the construction method of prestressed construction design should pay attention to the location of prestressed hole in the design, according to the actual requirements of the location of the hole to make a reasonable arrangement, and to achieve the strict requirements of the grouting. Hole made of the wall should be tight, so that holes can not be easy
