Publication: Direct Steerable Pipe Thrusting
Abstract
The design process for a direct steerable pipe thrusting (DSPT) installation draws from both horizontal directional drilling and microtunneling. This chapter discusses the following topics as they relate to the engineering design of DSPT installations: geometric design, thrust force estimate, hydraulic fracture evaluation, overcut and settlement, slurry and lubricating fluid considerations, launch and reception area considerations, and acceptable geometric tolerances. The geometric design for a DSPT installation typically consists of five basic elements: launch tangent, launch curve, bottom tangent, reception curve, and reception tangent. Engineers should use sound engineering judgment when evaluating methods to estimate the total thrust forces. The MTBM can be launched from the ground surface or from a shallow shaft and pit. If launched from the ground surface, consideration should be given to the use of a conductor casing to provide fluid containment, support of adverse ground, and a controlled launch for the MTBM.
