Are we approaching the universal shield?

For political and ecological reasons, the trenchless or underground construction method has become an essential part of establishing underground infrastructural supply and disposal networks in our cities. In the last decades, the major developments have focused on improving the machine technology with a view to create one machine type that alone is able to excavate the respective underground cavity independent of the geological and hydro-geological limiting conditions. The main focus of the following presentation is one shield machine type that may be seen as the forerunner of a universal shield.

Combined in-line inspection of pipelines for metal loss and cracks

As pipelines grow in age it is of ever growing importance to provide operators with precise and reliable inspection data in order to perform advanced integrity assessment calculation and optimize maintenance processes. Until recently the inspection of a pipeline regarding metal loss and cracks not only constituted the need for two separate inspection runs but also the use of two separate tools. This paper will introduce a range of advanced in-line inspection tools that incorporate the ability to be used for quantitative metal loss and wall thickness as well as crack inspections. These tools, utilizing ultrasound technology, make use of a new generation of electronics and an entirely new design of sensor carrier to enable metal loss and crack inspection surveys to be performed with a single tool in a single run. The paper will explain the physical principle used, introduce the tool technology, introduce a case study and present the operational advantages to the operator.

Insituform BlueTM to rehabilitate 1200 meters of Calgary water main with PolyFlexTM: trenchless method will save valued spruce trees

Insituform Blue, a division of Insituform Technologies, Inc., will renew 1200 meters of a 12-inch water distribution main in Calgary, Canada. The City of Calgary chose Insituform Blue’s trenchless pipe renewal process in an effort to avoid the removal and replacement of a number of spruce trees along a 1200-meter water main. The trenchless project will make it possible to save 149 spruce trees that the city values at $717,000. Traditional “dig and replace” methods would have required cutting down the trees, which are valued not only for their price, but also their environmental significance.

Pipeline scanning: Novel technology for detection of voids and internal defects in non-conductive buried pipes

Non-conductive buried pipe systems deteriorate over time under the action of various applied and environmental loads, chemical and microbiological induced corrosions, and differential settlements. A key for effective infrastructure management practices is the availability of reliable and timely inspection data that serve as the basis for the selection of proper rehabilitation/replacement methods. CCTV inspection is limited to detection of visible defects on the inner wall of the pipe. Defects hidden beneath encrustation, cement mortar lining or a thermoplastic liner, as well as voids immediately outside of the pipe, are currently difficult if not impossible to detect. It is proposed to develop a novel inspection technology, employing ultra-wideband (UWB) pulsed radar system, for detecting “below surface” defects, corrosion, and out-of-pipe voids in non-metallic buried pipes. This paper presents the theoretical foundation for the proposed method, followed by the results of a detailed numerical simulation. The numerical simulation employed custom-developed finite difference time domain (FDTD) code using a cylindrical coordinate system. Results from simulating the scanning of selected soil-pipe interface scenarios are presented. Experimental validation efforts of the proposed pipe scanning approach are also described.
