Cotswold Canal Trust – Bank Stabilisation

Cotswold Canal Trust got in touch via our website in regards to a bank on the Thames and Severn canal that needed stabilising. They had heard about us from one of our previous customers, who we helped with the Dursley Tree House project featured on Grand Designs in 2016.

One of our team visited the site at Ham Mill Lane in Stroud to discuss a solution to stabilise the failed canal bank with the volunteers from the trust. A screw piling solution to support the gabion retaining structure was developed with their Structural Engineer to install 60R screw piles both vertically and raked at 45 degrees using our 400H handheld anchor driver. This stabilisation would allow the Thames and Severn canal to be dredged. The work also formed a small part of a wider effort to eventually reopen the canal for public use.

As a result of our solution and the volunteer team's hard work, more material was prevented from falling into the canal, and they were able to support an adjoining neighbour’s garden from falling further down the hill.

The volunteers were inexperienced in screw piling so an engineer attended site to provide training on the safe use of the equipment. We assisted them with safe working methods to allow them to pile at 45 degrees on a steep slope.

“We had a good session of familiarisation training with one of your engineers on Wednesday . I would just like to say how pleasant and helpful he was, it was a pleasure to work with him.”

Bob Ambury, Cotswold Canal Trust

We enjoyed working with the Cotswold Canal Trust as the team are all volunteers, so they were keen to learn and get stuck in.

We are now assisting the trust with the design of a further 4m high gabion retaining wall which will be supported on screw piles. We are keen to see how this second project progresses and hope to continue to be involved with the wider project of re-opening the Thames and Severn Canal for public use.

If you have a project in mind and are considering using screw piles due to their many benefits, please don't hesitate to get in contact with us.

625kN Pile Test – Restricted Access London Site

When configuring suitable screw piles for a project, our Engineers rely heavily on soil properties determined from geotechnical investigation. Often undertaking soil testing using the ABC Anchors soil test probe, or commissioning a full soil investigation (SI) report from a geotechnical engineering firm provides us with sufficient design information. On small projects, use of our soil test probe instead can significantly reduce the cost compared to an SI report and provide similar results for specification purposes.

There are occasions however when pile testing is necessary to confirm our pile specifications.

ABC Anchors was recently contacted by a Client looking to install screw piles for a residential project in close proximity to the Thames in London. From an initial review of the SI it was understood that the site was underlain by a thin layer of dense gravels, however the soil properties below this were not described in the report. Being London based, an area known for weak Clays, and with a site in such close proximity to a river; it was decided that the soil report could not be relied upon alone. As the project required over 50 piles to be installed with design safe working loads of 20 tonnes per pile, it was critical to test the pile under load to confirm that any settlement was within acceptable limits.

ABC Anchors installed an 89R test pile to an installation torque of 25kNm using our Autoguide 2500X torque head mounted on a 3 tonne excavator. Typically excavators between 5-10 tonnes are used to install piles of this size, however as the site access was restricted to a small alleyway only 1.5m wide, a 3 tonne excavator was the only option. It was a testament to our Engineering team’s ingenuity and the skill of our installers that installation torques of this magnitude were achieved using such a low powered machine.

The pile was tested using our recently redesigned ABC Anchors testing equipment and experienced only 2mm of settlement when loaded to the pile’s ultimate load capacity of 62.5 tonnes. The Federation of Piling Specialists suggest that allowable settlement should be no more than 10mm under working loads.

The testing was a complete success and confirmed the suitability of our 89R rock tip pile for the project.

Garden Structure – Karen’s Childcare

ABC Anchors were approached to assist in a solution for foundations at Karen’s Childcare. They wanted to expand the outdoor area for the children and the available space had a few challenges to overcome.

Site access and foundation positioning was limited, so screwpiles were identified as the best solution by the Client. The piles were to be installed behind a retaining wall and next to a boundary wall; therefore they needed a vibration free and non-destructive installation method to prevent damage.

We used our 400H Handheld pile installer due to a lack of space, ensuring a smooth installation. There was no damage to the wall, as the piles transferred load from the structure to below the wall to prevent it failing due to the additional load of the garden structure.

Our lightweight garden piles were specified by the team here as they were ideal for supporting the low loads (up to 2 tonnes per pile) and are suitable for most soil conditions. The 8 pile system was installed in a day and once finished, the structure could be built instantly, as screw piles are unique in not requiring any wet trades. This removes the time delay in the build for curing.

Our customer was happy we were able to find a solution to building on this tricky site and we are pleased to say they have now completed their garden structure.

“ABC Anchors provided an 8 screw pile solution in a difficult location that was installed by a very professional team of two. it is a great system that is providing support to our Outdoor Structure which was designed, manufactured and installed by Beyond Timber of Dinnington.”

David Ellison, Karen's Childcare

RD Residential – Garden Studio

This project involved the construction of a timber-built garden studio in West London.

Screw piles were a preferred choice for the foundations, as the proposed location for the structure was at the base of a mature tree and in a tree root protection area.

The access to the site was also restricted allowing only hand held equipment to be used.

Both the customer and contractor for the build were new to screw piles and had been referred to us by their structural engineer, all the information was provided to each party and the system and method was approved.

The 60R product range was chosen due to the loading and the structure, and the unique 400H Hand Held anchor driver was chosen for the installation. The ground conditions varied across the site so additional extensions were used to achieve the required torque for the design load.

The foundations for the garden studio were successfully completed and the contractor was very happy with the service received:

“From start to completion ABC Anchors were a pleasure to deal with, very supportive, and easy to talk to when queries arose.  We would highly recommend both their products and service and will definitely be using them again for any piling needs we have.”

Ed O'Donnell, RD Residential

Easter Glentore Wind Farm

Easter Glentore is a wind farm situated between Glasgow and Edinburgh. This project entailed the jacking of two substation transformer units back to their original level.

The very poor ground was a mixture of soft undisturbed peat along with 5.5m of infilled stone that had over a period settled and caused the substation units to subside on one side. The movement of these units, both weighing in at around 12t was putting the underground electricity cables which are fed from the wind turbine at risk of damage.

ABC Anchors were asked to install screw piles along the subsiding edge of both substation units and bring them back to level using underpinning jacking brackets.The project needed careful planning due to the potential damage to the underground cables during the pile installation and the cost of having the wind turbine shut down for longer than necessary.

As always with the underpinning process, careful excavation to expose the footings was the first operation. The units were both set on 300mm thick concrete slabs so once the underside of these had been exposed localised pockets could be cleared away under the edge of the slab to allow for the jacking plates. The piles could then be installed using the ABC 500X torque head mounted on a 5t excavator. 4 piles were used on the smaller unit and 7 and the larger one. All the piles needed to be installed to 4kNm of torque which meant they were 6m deep in order to penetrate the hard undisturbed layer which started at 5.5m.

Once all the piles were in place the jacking brackets could be fitted and the jacking up process could begin. Care is always taken during this process to ensure the structure is loaded equally and no damage is incurred.

40kN hydraulic jacks were used on each pile making the leveling of the units a simple operation. With the piles all preloaded equally and the units back to level the jacking brackets could be locked in place using the M16 threaded bars and the jacks removed.

Finally the excavated soil is replaced with a type 1 scalpings and compacted to ensure there is no movement between the piles and the foundation.
