Embodiment Construction

[0023] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings, but it does not limit the scope of protection of the present invention. Those skilled in the art can also make partial changes to it. As long as they do not exceed the spirit of this patent, they are all regarded as equivalent replacements for this patent. , are within the protection scope of this patent.

[0024] The installation of expansion joint devices can be divided into two processes according to the construction sequence: first install the joint and then pave the road (abbreviated as the first installation method) and first pave the road and then install the seam (abbreviated as the after installation method). The post-installation method has more construction procedures than the first-installation method, but the post-installation method has the advantages of ensuring the smoothness of the expansion joint device and solving the difficu...

Abstract

The invention relates to a bridge installation method, in particular to an installation construction process of bridge expansion joints. To effectively improve the construction quality and the service performance of expansion joints, an expansion joint device used in the bridge installation method is installed in the sequence of paving the road before joint installation, and the installation method comprises the following steps: step 1, slotting: joint cutting, slotting and steel bar checking; step 2, installation: firstly, adjusting the initial expansion amount of the product according to the actual construction temperature, lifting the expansion joint device in place and then detecting the straightness and flatness; secondly, welding after elevation measuring and fixing; thirdly, installing partition boards and then cleaning preformed grooves; step 3, concrete pouring; and step 4, maintaining. The installation construction process can ensure the smoothness of the expansion joint device, solve the problem that two sides adjacent to the expansion joint device are not easily compacted, effectively reduce the potential failures caused in the construction links, and reduce the early breakage rate; and the installation construction process can improve the management and construction level of highway construction management and construction enterprises in the bridge expansion joint construction, and realize the fine construction by adopting the mode from extensive to intensive.

Description

technical field [0001] The invention relates to a bridge installation method, in particular to a bridge expansion joint installation construction technology. Background technique [0002] The installation and construction of expansion joints is one of the last procedures of bridge construction. Since the construction is close to completion and opening to traffic, the construction period is very tight, so the construction personnel are prone to be negligent in their busy schedule, and do not follow the installation procedures and related operation requirements. In addition, after the installation of the expansion device, the concrete was opened to traffic before it reached the strength, which caused early damage to the anchoring concrete in the transition section, resulting in a decrease in the performance of the expansion joint. Therefore, the installation of the expansion joint device must have a reasonable construction period. [0003] In the past, there was a phenomenon ...
