Abstract:- Combined with the practical construction experience of the branch line jacking project of the sewage transmission system in Wuhan Dadong Lake core area, the construction technology of long distance double-hole curve pipe jacking in deep tunnel is studied under the conditions of ultra-deep and composite formation. Aiming at the difficulties of jacking the double F type concrete cylinder pipe with small diameter, long distance for single jacking and the complicated curve, the technologies including pipe jacking machine selection and specific design, pipe jacking initiation receiving under deep soil and high water pressure, curved jacking drag reduction for long distance composite formation, guidance and attitude control, long distance pipe jacking power supply, ventilation and slurry discharge, as well as the design of small diameter steel cylinder reinforced concrete pipe joint were studied. The application results show that the jacking construction is smooth and the effect is good.
