后张法预应力混凝上构件施工,在我国已有40多年的历史。但由于各地施工队伍素质和施工经验的差异,预应力混凝土的施工常出现质量问题,影响工程质量,应该引起重视。一、波纹管铺设波纹管的铺设、布置是预应力构件施工的重要环节,直接影响下道工序的顺利进行,也影响预应力构件的设计承载能力。因此,对预应力构件中波 The post-tensioned pre-stressed coagulation unit construction has been in China for more than 40 years. However, due to the differences in the quality of construction teams and construction experience, the construction of prestressed concrete often has quality problems and affects the quality of the project. 1. The laying and arrangement of bellows laying bellows is an important part of the construction of prestressed components, directly affecting the smooth progress of the next process, and also affecting the design and carrying capacity of prestressed components. Therefore, the wave in the prestressed component
