Bollard System and Method of Installation

Abstract

An anti-ram bollard assembly (1) and an installation of the same to arrest impacts are provided. The bollard assembly includes a base assembly (20), a bollard member (10) attached to the base assembly and at least one reinforcement member (32) attached to the base assembly. The base assembly may include an I-beam arrangement to provide increased strength of the base assembly. Several bollard assemblies may be connected to form a cohesive installation to achieve a high impact rating. To this purpose, rebars (104) may be provided to connect the base assemblies of adjacent bollard assemblies. Further, the bollard member may be provided as a hollow member and may be subsequently filled with a high-strength material to prevent failure of the bollard member when it is being struck.

Description

FIELD OF INVENTION[0001]The present invention relates to an anti-ram bollard assembly and deployment of multiple bollard assemblies to arrest vehicular attacks, and to prevent penetration of the vehicle.BACKGROUND OF THE INVENTION[0002]In recent years for security reasons, many prominent establishments such as government buildings, embassies, convention centres, public transportation hubs and other perceived terrorist targets have been equipped with barrier systems to protect the establishments from vehicle attacks. Especially if the vehicle is heavyweight or moving at high speeds or carrying explosives, the attack can cause extreme destruction.[0003]Various barrier systems have since been employed with the intention of protecting buildings and structures from attacks. Metal or concrete barriers may be erected around a building to obstruct vehicular penetration. In order to resist large impacts from speeding heavy vehicles, the barriers have to be massive, resulting in a less aesthe...

AI Technical Summary

Benefits of technology

"The invention is about an anti-ram bollard assembly and a barrier installation that prevents vehicles from penetrating. The bollard assemblies can be installed in shallow trenches without disrupting utility lines. The impact rating of the bollard assemblies is improved over conventional bollards of similar form factors. The bollard assembly includes a base assembly, a bollard member, and a reinforcement member. The reinforcement member is attached to the base assembly and extends perpendicular to the bollard member. The bollard assembly is designed to receive rebars to connect adjacent bollard assemblies. The arrangement of the reinforcement member and the network of rebars provides an effective impact load transfer and stabilizes the installation when an impact is received. The invention is advantageous as it can prevent vehicles from penetrating the barrier installation without significantly increasing the dimensions of the bollard assemblies."

Problems solved by technology

Especially if the vehicle is heavyweight or moving at high speeds or carrying explosives, the attack can cause extreme destruction.

In order to resist large impacts from speeding heavy vehicles, the barriers have to be massive, resulting in a less aesthetic system.

Because utilities transmission such as electricity lines, water pipes and communications lines are often buried underground, deep excavation to install bollards is costly and time-consuming.

In addition, deep excavation causes disruption to utility services, inconvenience to pedestrian traffic, and often results in a less aesthetic landscape.
