Underground line monolithic roadbed expansion joint form reinforcing device and construction method thereof

Abstract

The invention relates to the technical field of engineering technical equipment and engineering approaches, in particular to an underground line monolithic roadbed expansion joint form reinforcing device and a construction method thereof. The reinforcing device comprises at least two angle iron structures which are in parallel arrangement and connected fixedly; an expansion joint form is arrangedbetween every two adjacent angle iron structures; connecting ends arranged below two ends of each angle iron structure are fixedly connected with the angle iron structure; the reinforcing device is arranged between sleepers and fixedly connected with steel rails through fixing structures. Compared with the prior art, the reinforcing device has the advantages that the reinforcing device which has combination structure is simple and feasible and is easy to mount and demount, has effect of enhancing control to the expansion joint forms, reducing deformation of the expansion joint forms, and improving appearance quality of expansion joints, and further is adaptable to ranges of various roadbeds, is easy and convenient, and enhances control to height of the connecting ends.

Description

[technical field] [0001] The invention relates to the technical field of engineering technical equipment and engineering methods, in particular to a reinforcing device and a construction method for an expansion joint formwork of an integral ballast bed of an underground line. [Background technique] [0002] At present, the overall ballast bed of the underground line adopts expansion joint formwork according to the design requirements. During the concrete pouring process of the ballast bed, the expansion joint formwork is easily deflected by the impact of concrete, and is prone to floating phenomenon. Under the different stress conditions of the concrete on both sides, the expansion joints are bent and not straight, which seriously affects the appearance quality. The late rectification and cleaning will increase the cost, and there are no better fixed methods and measures at present. Therefore, a new type of reinforcement device and construction method for the expansion join...
