Embodiment Construction

[0010] 1—column cap, 2—anti-blocking block, 3—double plate wave beam, 4—connecting device, 5—column

[0011] The guardrail of the present invention is further elaborated below in conjunction with the overall structure schematic diagram:

[0012] The guardrail of the present invention includes a wave beam 3, an anti-block block 2, a column 5, a column cap 1, and a connecting device 4, and is characterized in that: the double-plate wave beam 3 is fixed on the anti-block block 2 through the connecting device; the anti-block block 2 is fixed on the column through the connecting device 4; the column cap 1 is fixed in the column 5 through bolts; the column 5 is fixed in the foundation by embedding; the connecting device includes nuts, washers and bolts. In the process of use, the guardrail has a strong blocking ability, which can block medium and small vehicles and force them to stop moving. It has a strong guiding ability for large vehicles that cannot be blocked until they stop, e...

Abstract

The invention discloses a novel upper and lower double-plate corrugated beam guardrail, and aims to solve the problems of frequent traffic accidents, large accident loss and the like in the road traffic process. The novel upper and lower double-plate corrugated beam guardrail comprises stand columns, a double-plate corrugated beam, anti-blocking blocks, column caps and connecting devices, and is characterized in that: the double-plate corrugated beam is fixed on the anti-blocking blocks through the connecting devices; the anti-blocking blocks are fixed to the stand columns through the connecting devices; the column caps are fixed in the stand columns through bolts; the stand columns are fixed in a foundation in an embedded mode; and each connecting device comprises a nut, a gasket and a bolt. In the using process, the guardrail has high blocking capacity, can block medium-sized and small-sized vehicles and force the vehicles to stop moving, and has high guiding capacity for large-sizedvehicles which cannot be blocked to stop, so that the running safety of the vehicles is guaranteed; the guardrail has high collision energy absorption capacity, casualties and property losses can bereduced, and the safety of road traffic is improved.

Description

technical field [0001] The invention relates to the field of traffic safety, and is an upper and lower double-plate corrugated beam guardrail suitable for highways and expressways. Background technique [0002] In the field of road traffic, safety is the most important part of the entire road traffic process. How to drive safely and avoid personal injury or property loss is the goal of the development of road traffic safety related fields. On expressways, drivers will take risky behaviors of overloading and speeding in order to save time and improve efficiency. Due to the continuous construction and extension of expressways, the traffic volume is also increasing. The particularity of closed expressways makes it difficult to implement road management. Therefore, the probability of accidents is greatly increased. [0003] The guardrail of this invention adopts the upper and lower double-plate wave beam structure, and uses the deformation of the foundation, column, and wave be...
