Abstract

The utility model relates to transportation engineering, and discloses a strengthening device of a central separation zone waveform beam protective railing of a highway to prevent vehicles from crossing over the central separation zone protective railing after collision due to accidents. The existing central separation zone protective railing of the highway constructed in China adopts an anti-collision protective railing which is provided with an independent left part and an independent right part. When the vehicle collides the central separation zone protective railing due to the accidents, large impact force and inertia, the vehicles cross over the central separation zone protective railing and collide the vehicles from the opposite direction and great casualties and property loss are caused. Therefore, the two parts of the independent central separation zone anti-collision protective railing are connected as a whole to improve anti-collision property of the railing. The vehicles are effectively protected from accidents and crossing over when colliding the central preparation zone protective railing, and return to traffic lanes of the vehicles.

Description

Expressway Central Strip corrugated beam barrier bracing means

0001, affiliated technical field:

The utility model relates to traffic engineering, and Expressway Central Strip corrugated beam barrier bracing means prevents that vehicle from crossing median barrier because of accident bump.

0002, background technology:

At present, at the built current speedway of China, it is support post that the road center dividing strip adopts steel pipe, and corrugated beam barrier is continued being connected on the column of formula, forms left and right two width of cloth stand alone type anticollision barrier, reaches the purpose of separating the track.And when the vehicle of running at high speed has an accident and clashes into median barrier, because its powerful impact force and inertia, very easily cross median barrier to the track on opposite, and split by force collision with the vehicle generation of running at high speed on the track, opposite, cause great security incident.

0003, summary of the invention:

The generation of crossing median barrier behind the automobile impacting, on the basis of built median barrier, reinforce the connection the installation of device, make left and right two width of cloth independently guardrail reinforce pipe fitting by U-shaped buffering, they are connected to integral body, thereby reach the anti-collision ability that improves the median strip, when effectively stoping the automobile impacting median barrier and the generation of crossing makes it get back to self track.

Simultaneously in the device that reinforces the connection, a kind of novel, effective energy-absorbing, age inhibiting rubber cushion are installed, when Vehicular impact, to reach the effect of energy dissipating buffering.

0005, the specific embodiment:

At first 4., be installed on the column on the steel pipe post of built median barrier, and then install 5., will be processed at last on 5. 6. U-shaped buffering pipe fitting be connected in again, 7. firm bolt gets final product.
