Abstract:

This paper presents an application of the water jet cutting method to a treatment for obstructive piles on a planned line of shield tunneling. An automated cutting system and a monitoring system, developed for this treatment, support the work of cutting PHC (Prestressed High-strength Concrete) pile into small pieces before the passage of a shield tunneling machine, and then, the shield machine can excavate and move forward safely. The existing building on the obstructive piles is kept in the original state by underpinning works in combination. On the practical application, the water jet cutting work and the shield tunneling work have satisfactorily done in a short period of time.
