Has Every Soil Nail Got Its Collar?

Checking nail heads one by one is slow, and on a big slope it is easy to miss one. Walk the slope with a 360° camera instead: SpatialSense finds each soil nail in the photos and tells you whether it has its concrete collar, and a person accepts or rejects every finding.

The short answer

Soil nail heads are small, many and spread over a steep face, so checking them by eye is slow and easy to get wrong. SpatialSense adds a soil nail sweep to 360° walks: AI finds each nail in the photos and says whether it has its concrete collar. Nothing is final until a person looks at it. Each finding arrives as a proposal, and accepting it turns it into an issue you can assign and track.

What the soil nail sweep does

  • Finds each nailAI looks for soil nail heads in every 360° photo of the slope walk.
  • Checks the collarEach nail is classed as installed with or without its concrete collar.
  • Waits for a personEvery finding arrives as a proposal. Accept it to make an issue, or reject it to remove it.
  • Tracked to closedAccepted findings are issues like any other, with an owner, a due date and a status.
  • Alongside other sweepsIt runs on 360° walks next to the safety-issue and road-defect sweeps.

From slope walk to issue list

The walk takes as long as the slope. The checking takes a fraction of the time.

  1. A 360° walk over rough ground opened in SpatialSense, with the walk path in the corner

    Walk the slope

    Walk the slope or the berm with a 360° camera, and upload the walk to the project.

  2. The AI detection panel on a 360° walk in SpatialSense, with a list of results

    Run the soil nail sweep

    AI goes through the 360° photos, finds each soil nail and classes it as with or without its concrete collar.

  3. A list of issues on a phone in the Konnect app

    Missing collars become issues

    Accept a detection and it becomes an issue, assigned to the team that fixes it. Reject it and it disappears.

Why are soil nail checks so slow?

Search for soil nail software and you find design tools. Inspection, the part that repeats for the life of the slope, is still mostly done by eye.

Small, many, and high up

Nail heads are spread over a steep face, many of them out of easy reach.

Easy to lose your place

Counting rows and columns on a big slope by eye, it is easy to skip one or count one twice.

Notes that do not point anywhere

A note that says “row 6, nail 14” is hard to find again on the next visit.

A 360° walk keeps a dated picture of every nail head, and the sweep turns that picture into a list a person can check in one sitting.

The walk on the map

Every walk is placed on the map or the plan, so a finding points to a place on the slope.

Creating a team in SpatialSense with supervisors and members

Run by your supervisors

Supervisors and admins run the sweep; the crews that fix collars get their own team.

Every collar tracked

Accepted findings join the issue board, so you can see what is open and what has been fixed.

Your first slope

The sweep is switched on per organisation, so it starts with a demo.

  1. Book a demoWe switch on soil nail detection for your organisation and set up the project.
  2. Walk the slopeWalk it with a 360° camera, on the berms or along the toe, and upload the walk.
  3. Run the sweepA supervisor or admin runs the soil nail detection on the walk.
  4. Review the findingsAccept or reject each one. Accepted findings become issues.
  5. Assign and closeSend the missing collars to the team that fixes them, and track them to closed.

Frequently asked questions

Can AI inspect soil nails?

In SpatialSense, AI finds each soil nail head in the 360° photos of a slope walk and classes it as with or without its concrete collar. A person then accepts or rejects every finding, so the AI never decides on its own.

What happens when I accept a finding?

It becomes an issue on the spot where the nail is, which you can assign to a team with a due date and track to closed. Rejected findings disappear.

Who can run soil nail detection?

Supervisors and admins. The feature is switched on per organisation, so book a demo to have it set up. The platform itself has a 30-day free trial with no card details.

Which camera do I need?

Any 360° camera. Trace records with the Insta360 X4 and X5, and footage from other 360° cameras can be uploaded through the browser.

Does this replace a slope inspection by an engineer?

No. It gives the inspection team a dated photo of every nail head and a list to review. The judgement on the slope stays with the engineer.
