Development of Guidelines for Implementation of Horizontal Directional Drilling
摘要:
The objective of this study is to (a) document performance of recent selected horizontal directional drilling (HDD) installations in Illinois and elsewhere if available, (b) conduct a survey of selected HDD contractors regarding their experience and needs and (c) develop guidelines with quantitative metrics that can be used as the basis for evaluating proposed HDD installations for IDOT permit review and construction projects. Issues to be addressed are to define the conditions under which HDD is feasible and can be allowed. This includes addressing current IDOT concerns regarding aspects of HDD during construction and for the lifetime of the installation.
