Calculation of Pulling Force of Boring Head in Rectangular Box Culverts Jacking-pulling Construction

Abstract:

The paper systematically introduced the calculation method of pulling force in axial direction deviation rectification of boring head and retraction control during boring intermittent in rectangular box culverts jacking-pulling construction with engineering example. Based on the theoretical analysis and relative calculation formula, accurate results can be obtained for jacking-pull construction with rectangular box culverts.
