| 摘 要： | 顶推法施工是沿桥轴线方向的桥台后设置预制场,设置钢导粱和临时墩、滑道、水平千斤顶施力装置.分节段预制混凝土梁段,用纵向预应力筋连成整体,将粱逐段顶出去(拖出去),再在空出的制梁台座上继续下一梁段浇注,,这样反复循环施工桥梁的方法叫顶推法施工.针对这一问题,提出了顶推法施工的技术原理及方法,并对项推施工的关键技术进行了探讨.

| Abstract: | Construction is the pushing of the axial direction along the bridge abutment set of prefabricated field guide to set steel beams and temporary pier,slide,horizontal jack force on device.Segmental precast concrete beam,with vertical tendons connected into a whole,will beam out the top section by section(dragged out),then empty out the system in the pedestal to the next beam girder casting,so that construction of the bridge relatedly cycle The method is called Pushing Construction.In response to this problem.a pushing of principles and methods of construction technology,and pushing the construction of the key technologies are discussed. |
