PROJECT DESCRIPTION:
This no-entry coating technique allows circular and rectangular shafts to be cleaned and coated using an automated spin cast method of application. A fully automated centrifugal spray unit coats shaft walls to any required thickness. The system is suitable for concrete access chambers and wet wells. It is a safe method of coating shafts as no personnel are required to enter during the coating process.

INSTALLATION

A rotating cleaning nozzle is connected to a high pressure water pump delivering 39,000kPa (5600psi) to enable thorough cleaning of the walls prior to coating. Coating is then applied using an integrated, fully automated system consisting of a mixer, pump and a centrifugal spray head. The centrifugal spray is guided up and down inside the shaft using a gantry mounted winch at a constant, controlled rate to enable the design thickness of mortar to be applied in several passes. The number of passes will determine the final coating thickness. Mortar can also be applied overhead to platforms and to benching when required.

AVAILABLE SIZES

The M-Coating system is suitable for concrete structures from 500mm to 3000mm in diameter.

MATERIALS

The M-Coating system is suitable for a range of corrosion protection mortars including normal and calcium aluminate cement and aggregate mix.

Project Description:

Assessment of access chambers and wet wells can involve significant OH&S risk, requiring confined space entry for inspections. The 3D Scanner mitigates this risk by removing the need for personnel to enter the access chamber.

Installation

The 3D scanner is operated via a display and control unit using a cable winch incorporated into a specially-fitted vehicle. It can also be used portably for difficult to access locations.

The system uses a highly sophisticated camera head on a pulley which scans the entire interior of the access chamber or wet well in a few seconds in a single vertical run using Panoramo technology. The image data is transmitted digitally to the operator and can be used as a live picture survey for on-the-spot analysis, or saved for later assessment by either Abergeldie or client personnel.

The software used for desk top analysis, allows the operator to stop at any position within the chamber, pan 360 degrees, zoom in and zoom out, perform an image capture and completely analyse the condition of the access chamber.

Available Sizes

The 3D Scanner can be used for access chambers from 400mm diameter upwards, with depth of up to 90m. The camera can process 360 degree images from within access chambers at speeds up to 350mm per second. The 3D Scanner uses two high resolution digital cameras with specially designed distortion-free wide-angle lenses. The diameter of the camera is only 250mm.

Project Description:

The latest tractor-mounted CCTV camera equipment is used to inspect and then provide a complete condition assessment in accordance with industry standards. CCTV surveys are the most common method of pipeline inspection and can be used as a standalone process or as the first part of the pipeline renewal process.

Abergeldie Watertech employs several experienced and specialised Operators and Engineers (including CPEng and RPEQ qualified) to prepare detailed assessment reports including recommendations, engineering assessments and liner designs to determine the most appropriate rehabilitation technique.

PROJECT DESCRIPTION:

Abergeldie’s Laser Profiling system provides computer generated pipe profile data. The Laser Profiler assesses the condition of a pipe by measuring the internal diameter, ovality (roundness) and capacity of a length of pipeline.
Laser profiling equipment is attached to existing CCTV cameras. In situ footage is captured by the cameras and then computer analysed to produce the end user condition reports.

PROCESS SUMMARY

  • A ring of laser light is projected onto the internal pipe surface
  • Laser image is captured by CCTV whilst camera moves through the pipe
  • Analysis is performed on the ring of light using specialised software to build a digital pipe profile

TYPICAL APPLICATIONS INCLUDE:

  • Determining the internal cross-sectional area of a pipe
  • Analysing capacity loss due to deformation
  • Analysing capacity loss due to corrosion
  • Quality assurance of new applications
  • Post-rehabilitation pipeline assessment
  • Quantifying defects, holes, and other imperfections on existing and new assets
  • Measuring pipe diameter

Project Description:

The Climb Robot is a Hachler pneumatic milling robot that is the latest in robotic development for the trenchless industry. It offers superior manoeuvrability, grinding power and reach in pipes and junctions that are otherwise difficult to access. It is suitable for removing the build-up of concrete, protrusions, tree roots and displaced joint grinding. Climb also performs T-Seal removal or edge and horn trimming, as well as the removal of small bore main liners and lateral liners. It can also be used to remove defective T-Seals in branch lines as an alternative to expensive and potentially damaging excavation.

The Climb Robot is operated by a continual process of sequential inflation then deflation of two air bladders. It can traverse the mainline and is then able to enter and climb up into the branch line. Once positioned at the defect, the bladders are inflated to hold the robot firmly in position so that the powerful milling head can be operated to repair the defect accurately. The Climb is able to tackle very steep inclines and drive through bends using its pneumatic drive to power its movement.

Available Sizes

The Climb Robot is specifically suitable for grinding work in small diameter pipelines and lateral connection pipes with diameters 100mm to 225mm.
