ENVIRONMENTAL SAFETY OF TRENCHLESS TECHNOLOGIES
EngineeringThe article provides an analysis of modern trenchless technologies for the construction of communication networks, which include pipelines for water and energy supply, electrical cables and communication cables. Since trenchless laying of communications involves creating a cavity in the soil, the relevant technical means and processes that occur in ...

Use of Trenchless Technologies in Infrastructure Rehabilitation and Development
Pipeline Engineering and Construction, 2004During the past few years, trenchless technologies have been gaining popularity in the area of buried infrastructure rehabilitation due to economic and environmental factors. The gap between infrastructure spending and needs , which was presented in the USEPA GAP report and was supported by the 2001 ASCE Report Card, prompted the need for non ...

The optimum choice of trenchless pipe laying technologies
Tunnelling and Underground Space Technology, 2006A mathematical model AZ-01, which enables the choice of optimum trenchless pipe laying technology for given input data, has been presented. In the framework of AZ-01 presentation, a classification of trenchless methods applied in the model has been given, together with the assumptions, limiting conditions, input and output quantities.

The use of trenchless technologies for transmission and distribution projects
Proceedings of IEEE/PES Transmission and Distribution Conference, 2002Trenchless technology (TT) includes the installation, renovation, or rehabilitation of underground utility systems without open-cut excavation. In the past, trenchless methods were commonly used for crossing an obstacle such as a road, railway, or river.

Trenchless technology research in the UK water industry
Tunnelling and Underground Space Technology, 1996Abstract The UK water industry has recognised for some time that there are a number of significant benefits available from using trenchless technology equipment for their pipeline works. In order to gather more information and guidance on the operation and use of trenchless systems, the industry has commissioned a series of research projects.

The application of trenchless technology in pipeline maintenance
2005Trenchless technology is method for pipe repair without mining. With today's improved equipment and materials many financial and socio-economics’ advantages are achieved. The trenchless technologies which are used in Croatia will be explained, as well as effects in the comparison with classic methods of repairing pipes.

An Opinionated Review of Trenchless Technologies for Pipeline Rehabilitation
New Pipeline Technologies, Security, and Safety, 2003The general term of "trenchless technology" dates to the early 1970s. This paper takes a hard look at the technology as well as materials that are in use. The goal of the paper is to examine what systems work and what are problematic for the rehabilitation of water and wastewater pipelines.

Effect of trenchless technologies on existing iron pipelines
Geotechnical Engineering, 2005Impact moles and directional drilling units form tunnels of up to approximately 300 mm in diameter at a depth of 1–2 m. They are typically used for the installation of electricity cables or small-diameter pipelines. This type of tunnelling differs from conventional tunnelling owing to the lack of soil excavation.
