A slip form apparatus for forming a lining wall at an elbow tunnel comprises a skin plate(10), a skin plate movement member(20), a skin plate support unit(30) and a movable elbow guide unit(40). The skin plate provides a space for supplying concrete between the skin plate and an inner wall surface of an excavation ground(3) at an elbow tunnel so that a lining wall(5) is casted. The skin plate movement member includes a first curved frame(22) corresponding to the excavation ground and a first vertical frame(24) that fixes the first curved frame at a predetermined position on the excavation ground and has adjustable length. The skin plate support unit has an outer peripheral surface coupled with the skin plate and is provided at an outer side of the skin plate movement member. The movable elbow guide unit includes a second curved frame(42) and a second vertical frame(44). |
