Anchor Systems recently completed a slope stabilisation project at Tower Close, Horsham, to address a significant failure that posed risks to a local highway and private property. The project required an innovative approach to restore safety and ensure long-term stability.

Working alongside Ibex Consulting Engineers, we implemented a tailored geotechnical design featuring the Vulcan Earth Anchor, a highly durable and effective ground anchor system. A total of 27 anchors were installed in a diamond formation, complemented by Greenax erosion control mats and anchor drains to prevent hydrostatic pressure build-up. These measures delivered a robust solution, safeguarding the slope for its 120-year design life while protecting the environment.

Completed in just seven days, the project highlights our ability to deliver fast and efficient solutions for complex ground stabilisation challenges.

The Challenge

Traditionally, anchorage solutions for backstays use steel sledges with concrete kentledge blocks loaded on to them. This method requires large quantities of concrete blocks to be delivered to the site yard from Balfour Beatty’s Raynesway, Derby stores, then distributed to site using a Man 4×4 wagon with Hiab to install. The maximum number of blocks that can be carried at any one time is 4, meaning several trips are required per location. Additionally, temporary works are required, and Trackway is also needed to get the Man 4×4 to site.

 

The Measure

Together with the Innovations Team, the project team at ZL Great Missenden OHL pioneered the use of the Vulcan Earth Anchor system (distributed by Anchor Systems International) as an alternative to the traditional method of anchorage. These earth anchors are installed by inserting a drive rod into the anchor driving point and knocking them into the ground. The anchors are driven into the ground by using hand tools or excavators. Ground level anchor plates can be manufactured to the required angle for each individual location as needed.

This innovative alternative meant the reduction of materials used, decreased need for temporary works, removed the need for trakway installation, reduced the construction ecological footprint (for size, setup and delivery) and reduced transport costs. Additionally, the steel drive rods can be removed and reused again. Also recycled wooden pallets are used which are returned to supplier for re-use and the plastic shrink wrap used by Anchor Systems is a Biodegradable wrap.

 

“Having witnessed the use of this system on site, I found the ease of this installation, very impressive. The logistical reduction and numerous beneficial practicalities speak for themselves and I would like to see the implementation of this system on other schemes where possible”
Andy Robinson, Project Supervisor National Grid.

 

The Results

 

• Reduce relative project ecological footprint through reduction in temporary works and removal of required trakway installation (the need for 915m of trakway was mitigated)

• Reduced need for possible trakway ecological mitigations (i.e. trakway sealing for Great Crested Newts/reptiles)

• Delivering a cost saving of £11,849.74 (trackway and transportation costs)

• Material reuse

• Reduced project carbon footprint for backstays from 260,775kg to 7,727kg, for a total saving 253,048kg CO2*

Did you know that concrete is the most destructive material on Earth?

It is the most widely used man-made material in existence. It is second only to water as the most-consumed resource on the planet. In an ever-changing world where we are trying to reduce our carbon footprint, we are overlooking one of the biggest causes. Concrete is said to be responsible for around 8% of the world’s CO2 emissions. We have focused largely over the past several years on reducing our plastic use, yet all the plastic produced over the past 60 years amounts to 8bn tonnes, the cement industry pumps out more than that every two years.

 

We are not saying never use concrete. There is a place for concrete until we find something else that compares with it without the negative impact on the environment. But why use concrete unnecessarily?

 

When looking at foundation systems, instead of digging up vast areas of earth and filling them with concrete, look at alternatives.

 

The Anchor Post and Anchor Screw are made up from 100% recycled British steel, do not require any concrete to hold them in place and there is no digging required or removing of the soil. As there is no concrete there is no drying time and installations can be completed in a single visit. The unique dome head allows for adjustments to be made easily and simply. Bespoke interface plates can be designed to suit each individual application.

On a recent project with Balfour Beatty and Network Rail (see here), our system was used instead of concrete and the below results were recorded:

 

• 60 per cent time saving on foundation installation

 

• 40 per cent cost saving of £369 per metre to £221 per metre (derived from man hour savings, elimination of plant requirements, reduced possession requirements)

 

• 73 per cent embodied carbon reduction on materials, equivalent to 13,920kg CO2e and 89.4 per cent material saving

 

• Zero on-track plant and zero water consumed

 

• UK manufacturing and local materials, eliminating mainland European transportation miles

A Vulcan Earth Anchor^® is a percussion driven mechanical ground anchor. It can also be referred to as an Earth Anchor or Percussion Anchor.

Vulcan Earth Anchors are used as a cost effective and rapidly installed system to provide a positive force on a verity or projects.

The Vulcan Earth Anchor range was designed by Anchor Systems (International) Ltd as a simple, reliable and cost-effective ground anchoring solution with the ability to provide immediate loading capacities from 1 – 450kN in displaceable ground conditions with extensive applications.

 

The concept involves a specially designed earth anchor with a larger surface area, attached to high yield tie bars or tendons to suit a variety of conditions, being driven into the ground where it is locked in position. The tensile load is applied, and the exposed end locked off and terminated.

 

With their ease of use and speed of installation, Vulcan Earth Anchors provide a time and cost saving alternative to more traditional means of anchoring, particularly where tight programme schedules are involved. This combined with the wide range of sizes available means that the Vulcan Earth Anchor has gained recognition across a vast array of applications internationally.
