Download or read book Surface Profiling and Jacking Force for Guided Boring Method written by Md. Tareq H. Khondoker and published by . This book was released on 2016 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: Trenchless technology has brought a new era in pipeline installation, overtaking the customary open cut method. Several new trenchless installation techniques are now practicable, among which Guided Boring Method (GBM), pipe jacking and microtunnelling are most remarkable. All these methods are performed by jacking. In spite of having numerous advantages, some aspects associated with the aforementioned trenchless methods still need to be improved. GBM is one of the most widely used trenchless techniques to install pipelines with grade precision. As the length of these projects is much smaller than other underground projects (e.g. tunnels), conducting geotechnical investigations for GBM becomes unjustified at times due to budget constraints. Therefore, contractors will often conduct GBM installations without performing a proper subsurface investigation, which may lead to unusual consequences for the project. Since GBM consists of an initial pilot tube installation with further borehole reaming, the drilling parameters during the pilot tube installation phase may be used for subsurface profiling, which can help operators select proper drilling tools for the next reaming stages. This thesis firstly investigates the effectiveness of drilling parameters during pilot tube installation for subsurface profiling using drilling indices for a GBM project in Edmonton, Alberta, Canada. Five drilling indices, which were proposed for vertical drilling, were used to obtain the comparative strength of soil throughout the drive length. The results indicated that all five indices could identify the soil transitions in the drive length. However, the indices can only give a comparative strength measurement of soil throughout the drive length, not the exact soil strength. Vertical earth load on pipes is an important aspect as it largely affects the jacking force during pipe jacking/microtunnelling. Although there are several methods to determine the normal load, the difference among them in calculating vertical normal stress is quite large. This thesis secondly provides an extensive analysis of nine different models/standards and their variations based on experimental data as well as a parametric study. The results show that some models predicted normal stress values close to the measured value, while the others give much higher or lower value than the measurement. This discrepancy of calculated normal stress using different methods from measured value is due to the variation of assumptions of different parameters. To identify the influence of parameters on normal stress, a parametric study is also conducted to reveal the effect of different parameters on arching factor as well as normal earth stress.

Download or read book Pilot Tube Microtunneling written by Vamseedhar Gottipati and published by . This book was released on 2011 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: Trenchless technologies have emerged as a viable alternative to traditional open trench methods for installing underground pipelines and conduits. Pilot Tube Microtunneling, also referred to as the pilot tube system of microtunneling, guided auger boring, or guided boring method, is a recent addition to the family of trenchless installation methods. Pilot tube microtunneling originated in Japan and Europe, and was introduced to the United States in the year 1995 (Boschert 2007). Since then this methodology has seen increased utilization across North America particularity in municipal markets for the installation of gravity sewers. The primary reason contributing to the growth of pilot tube microtunneling is the technology's capability of installing pipes at high precision in terms of line and grade, in a wide range of ground conditions using relatively inexpensive equipment. The means and methods, applicability, capabilities and limitations of pilot tube microtunneling are well documented in published literature through many project specific case studies. However, there is little information on the macroscopic level regarding the technology and industry as a whole. With the increasing popularity of pilot tube microtunneling, there is an emerging need to address the above issues. This research effort surveyed 22 pilot tube microtunneling contractors across North America to determine the current industry state of practice with the technology. The survey examined various topics including contractor profile and experience; equipment, methods, and pipe materials utilized; and issues pertaining to project planning and construction risks associated with the pilot tube method. The findings of this research are based on a total of 450 projects completed with pilot tube microtunneling between 2006 and 2010. The respondents were diverse in terms of their experience with PTMT, ranging from two to 11 years. A majority of the respondents have traditionally provided services with other trenchless technologies. As revealed by the survey responses, PTMT projects grew by 110% between the years 2006 and 2010. It was found that almost 72% of the 450 PTMT projects completed between 2006 and 2010 by the respondents were for sanitary sewers. Installation in cobbles and boulders was rated as the highest risk by the contractors.

Available in PDF, EPUB and Kindle. Book excerpt: In the past decade, the field of trenchless technology has expanded rapidly in products, equipment, and utilization. This expansion would not have occurred without a strong increase in economic incentives to the user. Because the operating environment has changed, trenchless technology is often the preferred alternative to traditional methods of digging holes and installing conduits. The infrastructure in which we live has become more congested and has to be shared by several users. In addition, the cost of restoring a road or landscaped area after construction may be higher than the cost of installing the conduit. These factors add to the need for trenchless technology-the ability to dig holes without disturbing the surface. In some ways, trenchless technology is a futuristic concept. Ruth Krauss in a children's book of definitions wrote, "A Hole .. .Is to Dig." But this statement is not necessarily true. Today, a hole could be to bore.

Available in PDF, EPUB and Kindle. Book excerpt: The Eliminator is a new guided boring machine developed to address the market need for Pilot Tube Microtunneling (PTMT) installations in non-displaceable soils. This study is part of a multi-phase research project sponsored by the Natural Sciences and Engineering Research Council of Canada (NSERC) and the City of Edmonton. The main objectives of this research is to investigate the productivity of the Eliminator, risks associated with this machine, and methods to predict the required jacking force for installation of pipes. To achieve these goals, firstly a broad literature review was conducted on PTMT and the Eliminator as well as similar technologies such as microtunneling and pipe jacking. The study then introduces the first pipeline installation project performed with the Eliminator and assesses the technology's economic performance using the project's productivity and risk measures. The jacking force of the project was also monitored for analysis using hydraulic pressure transducers. Five existing jacking force prediction models used for technologies similar to the Eliminator were analyzed and compared with each force measured in the field. Based on the comparison, appropriate methods for estimating the jacking force of Eliminator projects are suggested.
