Problems solved by technology

At present, the more effective solution to the support void is to strictly control the installation elevation during construction, and use thin steel plate pads to plug the void support after the beam body is installed. This method is labor-intensive and time-consuming, and cannot fundamentally solve the problem. Support void problem

Embodiment Construction

[0025] Taking the existing bridge with support void disease as an example, the specific implementation steps of the disease solution are as follows:

[0026] (1) Remove the original support pad and clean it up;

[0027] (2) Install adjustable support pad stones at the original support pad stones (epoxy mortar can be laid for preliminary adjustment of elevation according to the actual situation); if Figure 1-6 As shown, the adjustable bridge support pad stone: includes a round head screw 1 and a base 3, and the inner wire steel plate 2, the stop pressure plate 12, the pressure bearing plate 13, and the sliding device 5 are placed on the base 3 in sequence from left to right , and the anti-resistance pressure plate 12, the pressure-receiving plate 13, and the sliding device 5 are sequentially connected, the inner wire steel plate 2 is placed at intervals with the anti-resistance pressure plate 12, and the center position of the left end of the pressure-receiving plate 12 is pro...

Abstract

The invention belongs to the technical field of bridge construction, and particularly discloses a method for solving the bridge bearing separation problem. In the installation process of bearing pinner of a newly-built bridge or the separation position of an existing bridge bearing, adjustable bridge bearing pinner is used for replacing traditional bearing pinner, a bearing is lifted by adjusting the adjustable bridge bearing pinner, and operation is completed after the bearing makes close contact with the bottom surface of the bridge. According to the method for solving the bridge bearing separation problem, construction is convenient and rapid, later-period maintenance is facilitated, and the bridge bearing separation problem is fundamentally solved.

Description

technical field [0001] The invention belongs to the technical field of bridge construction, and in particular relates to a method for solving voids of bridge supports. Background technique [0002] Due to the influence of factors such as construction accuracy and anti-arching of the beam body after prestressed tension, a large number of bridges have support voids, resulting in varying degrees of damage to the support, beam body and bridge deck in operation. At present, the more effective solution to the support void is to strictly control the installation elevation during construction, and use thin steel plate pads to plug the void support after the beam body is installed. This method is labor-intensive and time-consuming, and cannot fundamentally solve the problem. Support void problem. Contents of the invention [0003] In view of the deficiencies in the prior art, the present invention provides a solution to the void of the bridge support, which is convenient and fast ...
