Anchoring reinforced structure of overhung section for reinforced concrete pavement slab of highway along river

Abstract

The invention discloses an anchoring reinforced structure of an overhung section for a reinforced concrete pavement slab of a highway along a river. A plurality of steel rope buttresses are arranged on the reinforced concrete pavement slab, and positioned outside a residual roadbed; a plurality of anchor rods are arranged on a mountain and correspond to the steel rope buttresses one by one; the outer end of each anchor rod is fixedly connected with the inner end of a steel cable; the anchor rods correspond to the steel cables one by one; the outer ends of the steel cables are fixedly connected with the outside of the reinforced concrete pavement slab; connecting parts of the steel cables and the reinforced concrete pavement slab are positioned outside the steel rope buttresses; and the middles of the steel cables are contacted with the tops of the steel rope buttresses. The anchoring reinforced structure has the benefits that the anchoring reinforced structure can be used for temporary reinforcement treatment on a road section with river water undercutting and flood damage hidden dangers; the temporary traffic safety of the road section before permanent treatment is ensured; enough preparation time is won for permanent treatment engineering; the structure is simple; construction requirements are not high; and the structure is very suitable for special geographical environments of mountain highways built along mountains and rivers.

Description

technical field [0001] The invention relates to a road reinforcement treatment technology, in particular to an anchor tension reinforcement structure for a suspended section of a reinforced concrete road slab along a river. Background technique [0002] The total mileage of highways in western my country exceeds 1.02 million kilometers, including 274,000 kilometers in Sichuan Province, 110,000 kilometers in Chongqing City, 125,000 kilometers in Guizhou Province, 204,000 kilometers in Yunnan Province, 150,000 kilometers in Xinjiang Uygur Autonomous Region, and 106,000 kilometers in Gansu Province. The Tibet Autonomous Region is 52,000 kilometers away. Among the total mileage of 1.02 million highways, 40% of the road sections of nearly 400,000 kilometers are built near mountains and rivers. The special geographical environment inevitably makes these road sections have serious hidden dangers of water damage; [0003] In addition to sudden geological disasters, most of the c...

Problems solved by technology

[0004] At present, there are no very effective prevention and control measures for the water damage disasters caused by the long-term erosion of the river water, and basically stay in the post-disaster engineering restoration and reconstruction. The main reason is that these in-service roads were built earlier , as well as the year-by-year changes in geology and landforms, resulting in no permanent treatment for the erosion of the river during the construction. The entire road section can only be rebuilt after the flood disaster occurs or when the hidden dangers are serious. The cost is huge, time-consuming and labor-intensive, and requires a long preparation period for construction preparations; it is needless to say that the road section must be rebuilt after the flood disaster occurs, but for the road section with hidden dangers, how to solve the problem after the hidden danger is discovered and before it is permanently treated? Ensuring the driving safety of road sections during the transitional period is a problem to be solved
