The invention relates to the field of shield construction, in particular to a high water pressure soft soil stratum HFE combined type shield starting method. The technical problem of receiving of starting of a soft soil stratum shield tunneling machine under a condition of high water pressure is solved. The shield starting method comprises the following steps that rotary jetting reinforcing is constructed according to design drawing requirements; freezing pipes and temperature measuring holes are constructed, temperature measuring lines are arranged, and freezing is conducted after freezing equipment and a freezing pipeline are mounted and debugged; shield starting preparation is conducted; the outer portion of a door opening steel ring is connected with an externally connected steel ringdevice through a bolt; after shield starting preparation work is completed and freezing and reinforcing are conducted, a door opening fencing structure is broken and removed; the shield tunneling machine jacks and marches forwards; pressure buildup is conducted on a working face of the shield tunneling machine; the freezing pipe in a tunneling outline is pulled and removed, and other freezing pipes continue to work and conduct freezing; an arc-shaped plate is welded to the outer vertical face of the externally connected steel ring device, after the shield tunneling machine completely enters the externally connected steel ring device, synchronous grouting is started, and starting tunneling is completed. The high water pressure soft soil stratum HFE combined type shield starting method has obvious advantages when being particularly applied to a soft soil stratum which is high in waterhead, large in water yield and not equipped with a starting rainfall condition, and has good popularization prospects.
