Reinforced concrete flower box guardrail and construction method

Abstract

The invention provides a reinforced concrete flower box guardrail and a construction method, the reinforced concrete flower box guardrail mainly comprises a concrete guardrail, a reserved flower box position, a box girder cantilever arm, a main cross beam, a walking wheel, a jack and a steel bar binding jig frame, the reserved flower box position is arranged on the concrete guardrail, and transverse main reinforcements of the concrete guardrail are positioned and bound by adopting the steel bar binding jig frame. The reinforcing steel bar binding jig frame is placed on a box girder cantilever arm and is jacked and fixed through a jack after moving in place, a diffusion steel plate is arranged on the lower portion of the jack, a weight is arranged in the middle of the reinforcing steel bar binding jig frame for stabilization, a vertical stand column is arranged on the outer side of the reinforcing steel bar binding jig frame, and a reinforcing steel bar supporting frame is arranged on the vertical stand column. The positions of the steel bar supporting frames are fixed through bolts on the sliding fixing grooves, and supporting steel plates are arranged at the ends of the steel bar supporting frames. According to the construction method for the reinforced concrete flower box guardrail structure, the engineering cost is effectively reduced, the construction speed is increased, and good technical and economic benefits can be obtained when the construction method is applied to actual engineering.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to a reinforced concrete flower box guardrail and a construction method. Background technique [0002] The problem of traffic safety has become a hot issue that the whole society pays attention to. As an important traffic safety facility on the highway, guardrails have a great influence on road traffic safety whether their design is reasonable or not. Concrete crash barriers have the advantages of low maintenance costs and good protection performance. In recent years, greening construction has advanced rapidly, and the flower box guardrail structure has injected new vitality into urban development. It not only improves the living environment quality of residents, but also enhances the reputation of a city. [0003] At present, the construction of conventional reinforced concrete flower box guardrail has problems such as low efficiency of steel bar binding construction, difficulty...
