Method for treating corbel with longitudinal crack in riverine highway

Abstract

The invention relates to a method for treating a corbel with a longitudinal crack in a riverine highway, overcoming the defect that the prior art comprising the prior radical treating effects of excavation, back filling, grid laying, grouting, impermeable wall setting and the like can not fundamentally inhibit the destruction function of transverse pulling force to beds. The invention adopts the corbel as a reinforced concrete member, the corbel is longitudinally laid perpendicular to the highway below the face of the highway, and the development and the extension of the longitudinal crack can be effectively prevented by utilizing the favorable tensile property of steel bars. Namely, the corbel has the function of strengthening the tensile capability of embankment foundation soil bodies or fillers, the placement direction of the steel bars inside the corbel is vertical to the direction of the crack, the steel bars can completely bear transverse horizontal force borne by the beds because of favorable tensile property, the longitudinal cracking of the beds is prevented, and the reflection and the diffusion of the longitudinal crack of the beds towards the face of the highway are thoroughly cut off. For the service life of the highway, the steel bars are wrapt by a concrete material, and the durability of the steel bars can be effectively ensured.

Description

technical field [0001] The invention relates to a road reinforcement engineering construction method, in particular to a method for treating longitudinal cracks of a bolster along a river road. Background technique [0002] The road along the river not only bears the functions and functions of ordinary roads, but also undertakes the functions and tasks of the embankment along the river. Therefore, its subgrade and pavement must not only bear a large traffic load, but also must withstand Effects of river water level rise and fall and scouring. However, when roads along the river deal with these two forces, problems usually occur, and the direct manifestation of the disease is mainly longitudinal cracking on the road surface. [0003] Before the present invention, various methods have been adopted to try to solve this problem, including excavation and backfilling, laying grids, grouting, setting anti-seepage walls, etc. As a palliative measure, it failed to fundamentally cur...

However, when roads along the river deal with these two forces, problems usually arise, and the direct manifestation of the disease is mainly longitudinal cracking on the road surface

[0003] Before the present invention, various methods have been adopted to try to solve this problem, including excavation and backfilling, laying grids, grouting, setting anti-seepage walls, etc. As a palliative measure, it failed to fundamentally curb the destructive effect of lateral tension on the subgrade, so the hazard has not been effectively resolved
