Overview:
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 soil-pipe interface, overcut, alignment, etc. Empirical formulas of jacking forces were reviewed. Comparisons on jacking forces with case studies were illustrated and discussed. New estimation method was also established and discussed.
