Bridge Protection Technology

ATG Access Stand: D70

Tested at 48kph (30mph), with an angle of attack to simulate a realistic bridge attack. Tested to both PAS 68 and IWA 14 the bollard was tested in an array of seven achieving a penetration of less than 1m.

The biggest challenge when it comes to bridge protection is ensuring that the structural integrity of the bridge deck is not compromised when installing security measures. Our new technology solves this with its super shallow foundation structure. 

Super Shallow & Quick to Install

The ATG Access Bridge Protection Bollard only requires a true depth of 40mm for installation; no other upstanding structure is required. No mechanical bolting or fixings are required during installation, the array simply sits within a very shallow excavation which may be planed away.

Installation of the test array was completed by MIRA civil engineers who had not seen the system before in just under 40 minutes.

A minimum array of 7 bollards is required and then individual modules can be added in singular units to cover the length required. The layout can accommodate a gap in the foundation between adjacent arrays to accommodate bridge expansion joints.

This innovative product is not designed to be reliant on digging into a sub-structure unlike other systems and can articulate to accommodate cambers and contours in a bridge structure.

Aesthetic Options & Handrails

Aesthetically, due to a low bollard height, the system is cycle-friendly. The bollard can be sleeved with a stainless-steel aesthetic sleeve (168mm diameter), still providing an incredibly slim profile.

Handrails and fencing can be accommodated to restrict pedestrian access anywhere along the array. Historic or heritage sleeve designs can be accommodated if required. The slim high-security core of this system can easily accommodate special aesthetics.

Bridge Deck Expansion Beam

This physical security solution can be used to span across bridge expansion joints to ensure that security measures are consistent along the length of a bridge deck. It can also be used to span across other obstructions such as service chambers or manhole covers.

Working in conjunction with the ATG Access Bridge Bollard system, with unconnected foundations, simulating a wide double bridge expansion joint. The structural foundation depth required for this system is only 40 mm, no other upstanding structure is required. The beam can be removed to allow for occasional vehicular access.

The Bridge Deck Expansion Beam was impact tested at the MIRA testing facility to the IWA 14-1 standard. Successfully arresting a 7,200kg vehicle travelling at 48 kph. The test simulated a bridge attack where the angle of attack was 30º. The system performed incredibly well and achieved a minimal dynamic penetration of 0.2m.

The system can be clad to accommodate a wide range of aesthetic options including bespoke heritage design. ATG’s design and engineering team can work closely with client design and architectural teams to ensure that the appropriate aesthetic is achieved.

The system has been designed to ensure that there are no exposed cavities into which foreign objectives may be placed. This is important when considering the overall security of the system.

 

Having pioneered shallow mount technology since its invention, ATG Access is proud to introduce our shallowest technology yet. This innovative new Bridge Protection Bollard sits within just a 40mm deep base plate, allowing it to sit within a bridge kerb without damaging the structural integrity of the bridge deck.
