随着我国铁路事业的不断发展,铁路施工建设日益增多。由于很多普速铁路要求在不中断火车行车的前提下进行施工,所以D型施工便梁得到了广泛的应用。通常在一个工程中使用便梁会需要多次纵移便梁。通过对三种常用的纵移便梁方法对比,重点介绍“整体法”纵移便粱的施工方法及特点。 With the continuous development of the railway industry in our country, the railway construction is increasing. Since many ordinary speed railways require construction without interruption of train traffic, D-type construction beams have been widely used. Often using a stool in one project will require multiple longitudinal shifts. Through the comparison of the three commonly used method of longitudinal movement of the beam, we mainly introduce the construction method and characteristics of the “whole method” longitudinal movement of the beam.
