Abstract
The utility model discloses a cast-in-place concrete anti-collision guardrail which comprises an anti-collision wall body. The anti-collision wall body is formed by a reinforcement cage cast-in-place concrete structure, a pipeline structure used for pipelining is arranged in a reinforcement cage in pre-arranged and penetrating modes, the pipeline structure is arranged in the anti-collision wall body in through and penetrating modes, and a connecting member used for being fixedly connected with an upper structure of a bridge floor is arranged on the lower portion of the anti-collision wall body. Due to the fact that the anti-collision wall body of the reinforcement cage cast-in-place concrete structure is adopted, the cast-in-place concrete anti-collision guardrail has energy dissipation and speed reduction effects and is strong in anti-collision capability, the pipeline structure is further pre-cast in the anti-collision wall body, and therefore penetrating arrangement of all kinds of pipelines on the way can be achieved. In addition, water-swelling rubber bars and a waterproof coating are further added, and the safety and the reliability of the cast-in-place concrete anti-collision guardrail are further improved.
Description
Technical field
The utility model relates to the bridge technical field, relates in particular to a kind of cast-in-situ concrete anticollision barrier.
Background technology
Along with the fast development of China's bridge building cause, the positive rapid growth of bridge mileage open to traffic, and the traffic safety problem of thereupon bringing also highlights day by day.Wherein, shortage good guardrail facility in bridge road surface is one of major reason that has an accident.
In addition, complicated along with technology such as traffic is electric, signal, controls, the structures such as track traffic now, urban elevated bridge are also widely by the double support that wears of doing various pipelines.
Therefore, those skilled in the art is devoted to develop a kind of energy dissipating deceleration effect that has, and crashproof ability is strong, and can meet the cast-in-situ concrete anticollision barrier that various pipelines on the way wear.
The utility model content
Because the above-mentioned defect of prior art, technical problem to be solved in the utility model is to provide a kind of energy dissipating deceleration effect that has, and crashproof ability is strong, and can meet the cast-in-situ concrete anticollision barrier that various pipelines on the way wear.
For achieving the above object, the utility model provides a kind of cast-in-situ concrete anticollision barrier, comprise crashproof body of wall, described crashproof body of wall is formed by the reinforcing cage cast-in-place concrete structure, the preset pipeline configuration of installing for pipeline that is equipped with in described reinforcing cage, described pipeline configuration connects and is located on described crashproof body of wall, and the bottom of described crashproof body of wall is provided with the connector that is fixedly connected with for the bridge floor superstructure.
Preferably, described crashproof body of wall is provided with the hydro-expansive rubber bar with the outer, bottom surface that described bridge floor superstructure is connected.
Preferably, the junction of hitting basifacial and described bridge floor superstructure of meeting of described crashproof body of wall is provided with waterproof coating.
Preferably, described connector is high-strength anchor bolt.
The beneficial effects of the utility model are:
The utility model adopts the crashproof body of wall of monolithic reinforced concrete structure, has energy dissipating deceleration effect, and crashproof ability is strong, and is embedded with pipeline configuration in crashproof body of wall, can meet various pipelines on the way and wear.In addition, the utility model has also added hydro-expansive rubber bar and waterproof coating, has further improved security reliability of the present utility model.
Be described further below with reference to the technique effect of accompanying drawing to design of the present utility model, concrete structure and generation, to understand fully the purpose of this utility model, feature and effect.
