预应力混凝土箱梁,特别是目前应用广泛的混凝土预制简支箱梁有许多优点。不需要长途运输箱梁,有利于进行施工管理,可以在保证工程质量的同时,缩短工期,降低成本,提高效益。预应力混凝土预制箱梁的施工特点主要是施工比较复杂,而且体积较大,而且由于工程质量的要求越来越高,因此,如何提高预制箱梁施工技术对整个工程作用重大,施工的质量控制也就成为重点和要点。
Prestressed concrete box girders, especially the widely used prefabricated concrete box girders, have many advantages. Do not need long-distance transport box girder, is conducive to construction management, can ensure the quality of the project at the same time, shorten the construction period, reduce costs and improve efficiency. The construction features of prestressed concrete prefabricated box girder are mainly that the construction is complicated and the volume is relatively large, and because the requirements of engineering quality are getting higher and higher, how to improve the construction technology of prefabricated box girder has a great effect on the whole project and the construction quality control It has become the focus and point.
