Description

A New Reinforced Combined Guardrail

technical field

The utility model relates to a protective device in the traffic field, in particular to a novel reinforced combined guardrail.

Background technique

There are many areas on highway bridges that cross high-speed rail and water resources. Once a vehicle overturns in these areas, it will affect the operation of high-speed rail and pollute water resources. The consequences are serious, so special protection is required. Due to the rapid development of large-scale vehicles in recent years, the original anti-collision barriers no longer meet the protection requirements and need to be greatly strengthened, and the cost of direct replacement projects is too high, and structural transformation must be carried out on the basis of retaining the original guardrails. In addition, in terms of noise reduction and anti-throwing, although some existing guardrails are equipped with devices such as noise reduction screens and anti-throwing nets, the noise reduction screens and anti-throwing nets are not effectively protected, and it is easy to hit them after the vehicle hits the guardrail. Anechoic screen or anti-throwing net, so that it falls off the bridge, causing secondary accidents.

Aiming at the problems in the related technologies, no effective solution has been proposed yet.

Contents of the invention

The purpose of this utility model is to provide a new type of reinforced combined guardrail, which is based on the original highway bridge guardrail, effectively improves the safety protection level of the guardrail on special dangerous road sections, is convenient for construction, good in economy, and has noise reduction effect at the same time.

For realizing above-mentioned technical purpose, technical scheme of the present utility model is realized like this:

A new reinforced combined guardrail, including the old guardrail and the reinforced guardrail located in front of the old guardrail, the bottom of the reinforced guardrail is provided with a concrete pouring soil layer, and the concrete pouring soil layer passes through the planting bars and the original pavement concrete foundation Fixed connection, the concrete pouring layer is provided with bolts, the concrete pouring layer is connected with the upper reinforced guardrail column base through bolts, the column base is provided with a column on the upper part, and several reinforcements are arranged between the column base and the column Ribs, beams are arranged on the columns.

Further, the old guardrail includes a concrete wall and an upper column, and an anti-throwing net and a sound-absorbing screen are sequentially arranged on the concrete wall and behind the upper column.

Beneficial effects of the utility model: the utility model provides a new type of reinforced combined guardrail by setting a reinforced guardrail in front of the old guardrail and relying on the old guardrail built according to the old standard. The concrete layer is poured by planting bars and the bolts in the concrete layer are connected to the base of the column, which increases the connection strength between the reinforced guardrail and the road surface; the new reinforced combined guardrail effectively improves the safety protection level of the guardrail on special dangerous road sections, and the reinforced guardrail is effective for vehicles. While carrying out safety protection, the protection of noise reduction and anti-throwing devices installed on the old guardrails is realized; by installing noise reduction and anti-throwing devices on the old guardrails, the sound absorption and noise reduction ability and anti-throwing performance of the guardrails are enhanced. The device has the advantages of reasonable structure, convenient installation, beautiful appearance, low cost, economy and practicability, and is beneficial to market promotion and application.
