Construction method of cast-in-place reinforced concrete guardrail

Abstract

The invention relates to a cast-in-place reinforced concrete barrier construction method. By slide positioning rings and lateral retaining plates, elevation limiting of positioning plates is realized;by the positioning plates, positioning limiting of longitudinal bars of a steel reinforcement cage is realized. Transverse connecting rods are arranged between the barrier steel reinforcement cage and an inside suspension rod and between the barrier steel reinforcement cage and an outside suspension rod, a top suspension rod is arranged between the barrier steel reinforcement cage and a top suspension beam, and a bottom supporting rod is arranged between the barrier steel reinforcement cage and a bottom transverse support. By transverse position adjusters, outside positioning tenons and a limiting groove plate, positions of an inside mould and an outside mould are limited. After firm connection of a joint end mould, a lateral hanging plate and a top connection plate, the transverse position of the joint end mould is limited through an internal ejector rod. A pouring hopper and a transverse tractor are distributed on a transverse bearing plate, an inner spraying pipe and an outer spraying pipe are arranged on two sides of a barrier and communicated with a top spraying pipe, and a bottom water gathering plate and a sewage collection tank are arranged below a reinforced concrete barrier. Onsite construction quality and construction structure integrality can be improved, construction difficulty is lowered, and maintenance quality is improved.

Description

technical field [0001] The invention relates to a construction method for cast-in-place reinforced concrete guardrails, which is convenient for binding and hoisting construction of reinforcement cages, good formwork support quality, high concrete pouring construction efficiency, easy maintenance and sprinkling construction, and can effectively protect the construction environment, belonging to the field of bridge engineering , suitable for cast-in-place reinforced concrete guardrail projects. Background technique [0002] With the development of our country's economy, the construction scale of bridge engineering is expanding continuously. As an important part of the bridge superstructure, the reinforced concrete guardrail is the last line of defense to protect life safety when the vehicle is out of control, and its construction quality is highly valued by the construction unit. However, reinforced concrete guardrails are easily affected by various factors in specific constr...
