Description

Anti-collision guardrail adding device for paving road surface of road traffic safety facilities

technical field

The utility model relates to an anti-collision guardrail heightening device for road traffic safety facilities, in particular to an anti-collision guardrail adding device for paving road surfaces of road traffic safety facilities.

Background technique

In the road traffic safety facilities, the anti-collision guardrail directly bears the impact of the vehicle when an accident occurs while driving on the road, and protects the vehicle from falling out of the guardrail and causing greater losses in the event of an accident. It is the most vulnerable traffic safety facility. broken device. The height of the anti-collision barrier is reduced due to road paving, so that the intensity of the impact force of the anti-collision barrier is greatly reduced, making it easier for the vehicle to turn out of the anti-collision barrier, and the safety is greatly reduced, which directly affects the vehicle on the road. safety. In the past, the solution to the reduction of the height of the anti-collision barriers due to road overlaying was to remove the anti-collision barriers when the pavement was over, then pull out the anti-collision barriers, and then use a pile driver to remove the anti-collision barriers. Drive it into the ground again, and then install the anti-collision guardrail on the anti-blocking block of the anti-collision guardrail, so that the newly installed anti-collision guardrail reaches the standard height of the original crash guardrail. This not only takes a lot of time and labor, increases labor intensity, and increases costs, but also increases the loss of the anti-collision guardrails that are newly driven into the ground due to the increase in the thickness of the asphalt after the road is overlaid.

Contents of the invention

The purpose of this utility model is to solve the above problems, to provide an additional device that can be lifted to the height of the original anti-collision guardrail without pulling out the anti-collision guardrail, and saves time and stretching force, high efficiency and low cost. Attach the device with crash barriers.

One of technical solutions of the present utility model is:

An anti-collision guardrail attachment device for paving road surfaces of road traffic safety facilities, comprising an anti-collision guardrail (5), an anti-blocking block (4) and connecting bolts (3), the lower end of the anti-collision guardrail (5) is fixed on In the subgrade (7), its upper end is provided with through holes for wearing and fitting connecting bolts (3), and the anti-blocking block (4) is installed on the top of the anti-collision guardrail (5) through the connecting bolts (3), and the anti-collision guardrail ( 6) It is fixed on the anti-blocking block (4) by connecting screws. The length direction of the elongated piercing hole (8) is consistent with the axis direction of the anti-collision guardrail (5).

Two of the technical solution of the present utility model is:

An anti-collision guardrail attachment device for paving road surfaces of road traffic safety facilities, comprising an anti-collision guardrail (5), an anti-blocking block (4) and connecting bolts (3), the lower end of the anti-collision guardrail (5) is fixed on In the subgrade (7), the feature is that the upper end of the anti-collision guardrail (5) is inserted with a sleeve (1), and the small-diameter insertion section (2) at the lower end of the sleeve (1) is inserted into the anti-collision guardrail (5) In the upper end of the casing (1), the upper end of the casing (1) is provided with a through hole for wearing the connecting bolt (3), and the anti-blocking block (4) is fixed on the upper end of the casing (1) through the connecting bolt (3). The plate (6) is fixed on the anti-blocking block (4) by connecting screws.

The sleeve pipe (1) has a length of 5-100cm and a diameter of 10-20cm, and a small-diameter insertion section (2) at the lower end of the sleeve pipe (1) has a length of 5-50cm and a diameter of 9-19cm.

The small-diameter insertion section (2) at the lower end of the casing (1) is provided with connecting bolts passing through the anti-collision guardrail (5).

The anti-blocking block (4) is provided with strip-shaped piercing holes (8) for piercing the connecting bolts (3).

The beneficial effects of the utility model are:

The utility model has a reasonable design. The height of the guardrail can be adjusted by adjusting the installation position of the connecting bolt on the anti-blocking block, and the height of the guardrail can be adjusted by adding a new section of casing to the original anti-collision guardrail. It meets the original height of the anti-collision barrier after paving the road surface, and retains all the functions of the original anti-collision barrier, and also increases the strength of the anti-collision barrier. The utility model can be quickly added to the original anti-collision guardrail before the pavement is not added or after the pavement is added, which not only has the effect of increasing the strength of the original anti-collision guardrail, but also the addition sleeve of the utility model can be added according to the future The height of the paving surface can be changed several times without damaging the original crash barriers. The utility model has the advantages of simple operation, time-saving and labor-saving replacement, high efficiency and low cost. The height of the guardrail can be adjusted without pulling out the original guardrail, which saves a lot of time for pulling out the tube and improves the construction speed. The bottom of the sleeve of the utility model is smaller than the top of the anti-collision guardrail, and is just installed on the top of the anti-collision guardrail. The tops of the railings are fixed together, and an anti-blocking block is arranged on the top of the casing to connect with the guardrail. The standard length of the upper part of the casing is 5-100cm, the standard length of the lower part of the casing is 5-50cm, the diameter of the upper part of the casing is 10-20cm, and the diameter of the lower part of the casing is 9-19cm.
