Abstract

The invention discloses a method for fixedly installing and leveling a base of a metal upright column of a bridge guardrail. The method includes leveling the base by the aid of a leveling device and fixedly welding the leveling device on a reinforcement cage by short reinforcing steel bars; removing the base construction leveling device and mounting corresponding base fixing devices on a bottom plate; and installing the metal beam-column guardrail after concrete is molded by means of pouring. The method has the advantages that a construction procedure is simple and is easy to learn, the leveling precision is high, the requirement on anchoring strength is met, the base leveling device can be reused, the construction speed is increased, the construction quality is improved, and the construction cost is reduced.

Description

technical field [0001] The invention relates to a bridge guardrail, in particular to a construction method for a metal column base of a bridge guardrail. Background technique [0002] With the emergence of large and medium-sized bridges in recent years, the application of metal beam-column guardrails on bridges has continued to increase. The metal beam-column guardrail structure can effectively protect out-of-control vehicles, effectively reduce the probability of the above-mentioned accidents, reduce the losses caused by accidents, and improve the traffic safety level of the expressway. In addition, the guardrail structure has a self-anti-glare function, which can effectively save the cost of anti-glare boards. At the same time, the guardrail structure is convenient for installing LED lighting equipment, which can effectively save the cost of light poles. [0003] The metal columns of the bridge guardrail should be vertical after being installed on the bridge body. On the ...
