Abstract

The invention relates to an installation method of a side span support, which comprises the following steps of: installing a cushion block and a jack above a pier body, and enabling a beam body to fall on the cushion block; the jack is jacked up to enable the beam body to reach a designed line shape, and the cushion block is dismantled; a side pier support is installed at the bottom of the beam body, and the side pier support and the beam body are fixed; and constructing at the top of the pier body to form a pier cap and a support pad stone, and connecting the side pier support with the support pad stone. The installation method of the side span support can be used for installing the side span support of a large-span bridge, the line shape of the bridge is controlled by jacking the beam body through the jack, the installation deviation generated in the bridge erecting process is eliminated, the installation precision of the side span support at the bottom of the beam body is improved, and the installation efficiency is improved. The difficulty of adjusting the side span support in a narrow space is reduced, and the installation efficiency of the side span support is improved.

Description

technical field [0001] The invention relates to the field of bridge erection, in particular to an installation method of a side span support. Background technique [0002] At present, in the construction process of the steel truss arch bridge, the mid-span closure and the bridge alignment after the closure are difficult to control. [0003] In the related art, the side span supports are usually first installed on the side piers, and then the bridge is closed by hoisting. After the bridge closure is completed, the closed bridge is then placed on the side span supports, and the side span supports are fixedly connected. with bridges. [0004] However, at present, the span of the bridge is getting larger and larger, and the weight of the bridge body is getting larger and larger. It is difficult to install the side span support first, and then complete the bridge closure by hoisting the bridge, and directly fix the beam on the side span support. It is difficult to realize the c...
