Abstract

The invention discloses an L-shaped reinforced concrete curb structure. The structure includes old curb stones. On the upper surface of the curb, an inverted L-shaped steel bar is installed in the new curb, and the lower part of the inverted L-shaped steel bar is anchored into the roadway, and the anchored part and the roadway are anchored by planting glue. In curb stones; steel handguards are fixedly installed on the upper surfaces of new and old curb stones. The invention also discloses the construction method of the structure. The invention has the characteristics of scientific design, simple and convenient construction, and is convenient and easy to implement, and is a novel reinforcement technology for the bridge protective body.

Description

technical field [0001] The invention relates to bridge protection technology, in particular to an L-shaped reinforced concrete reinforced curb structure and a construction method thereof. Background technique [0002] In recent years, with the improvement of road conditions, the phenomenon of speeding vehicles falling out of bridges and causing mass deaths and injuries has occurred from time to time. Therefore, it is imperative to strengthen the bridge protection system. The industry recommended standard of the People's Republic of China, "Design Rules for Highway Traffic Safety Facilities" (JTG / TD81-2006), clearly stipulates the construction of new bridge safety facilities. However, there are no regulations on how to strengthen the safety facilities of existing bridges. Therefore, the strengthening technology proposed for the protection system of the built bridge has broad application prospects. Contents of the invention [0003] The object of the present invention is t...
