Estimating the Jacking Forces for Pipejacking

 29 January 2020; 09:00 – 10:00 am US Eastern Standard Time (14:00 GMT)

The third ISTT educational webinar (available only to ISTT members) will be given by Prof. Keh-Jian (Albert) Shou, an expert in the world of pipe jacking and the vice-chair of ISTT. We will be using „Zoom Meeting” as a platform.  We plan to post the recorded video for our members at a later date. To participate in the webinar „live”, please sign up from the online form below.

This webinar series is organized by the ISTT Technology and Education Committee. ISTT plans more webinars in the coming months as our usual face-to-face meetings are on hold.

Among the others, pipejacking could be the most popular new installation trenchless methods. Jacking force is critical for a successful pipejacking, in which the control factors include overburden depth, frictional coefficient of the soil-pipe interface, overcut, alignment, etc. Empirical formulas of jacking forces were reviewed. Comparisons on jacking forces with case studies were illustrated and discussed. A new estimation method was also established and discussed.
