Embodiment Construction

[0045] The following is attached Figure 1-6 The application is described in further detail.

[0046] The embodiment of the present application discloses a bridge repair and maintenance structure. refer to figure 1 with figure 2 A bridge repair and maintenance structure replaces the original roadbed and is arranged between the bridge 1 and the approach road 2. The repair structure of the bridge 1 includes a reinforcement cage 3, a geotextile 4, a pad stone layer 6 and a concrete pavement 5. The two ends of the reinforcement cage 3 are connected to the The bridge 1 and the approach road 2 are in contact, the reinforcement cage 3 is in contact with the ground soil, the geotextile 4 is set on the inner wall of the reinforcement cage 3, the pad stone layer 6 is laid on the bottom wall of the reinforcement cage 3, and the concrete is laid on the pad stone layer 6 away from the reinforcement cage 3 side of the bottom wall. The new subgrade is used to replace the subsidence of the...

Abstract

The invention relates to the technical field of bridges, in particular to a bridge repairing and maintaining structure and a construction method thereof. The bridge repairing and maintaining structureis erected between a bridge and a guide road and comprises a reinforcement cage, geotechnical cloth and a concrete pavement; the geotechnical cloth covers the inner wall of the reinforcement cage, and the geotechnical cloth is fixedly connected with the reinforcement cage; the concrete pavement is arranged in the reinforcement cage and located on the side, away from the reinforcement cage, of thegeotechnical cloth. In the application, the probability of settlement of a roadbed is reduced; when a running vehicle runs at the bridgehead of a new roadbed, the running vehicle runs stably, the jumping and jolting conditions of the vehicle are reduced, the collision of the vehicle to the surface of the roadbed is reduced, and the effect of prolonging the service life of the roadbed is achieved.

Description

technical field [0001] The present application relates to the field of bridge technology, in particular to a bridge repair and maintenance structure and a construction method thereof. Background technique [0002] A bridge is a building built for the road to cross natural or artificial obstacles. It is a structure that allows vehicles and pedestrians to pass smoothly. Bridges are an important part of modern traffic roads. The completion of bridges greatly reduces people's traffic. time, making people's passage more convenient. [0003] The two ends of the bridge are connected with the approach road, and a section of subgrade is set between the bridge and the approach road, which plays a supporting role. The end of the subgrade is backfill soil, and the subgrade is prone to settlement under the action of traffic load and self-weight, which makes a staggered platform between the subgrade and the bridge. , causing the vehicle to jump at the bridge head. [0004] With respect ...
