摘要：
본발명은지반내관입된강관(鋼管)(10)에투입되는로드(15)에, 강관(10)과직교하는방향으로신축(伸縮)되는확경체(20)와, 확경체(20)의단부에설치되어확경체(20)가신축됨에따라강관(10)과직교하는방향으로이동되는압박체(30)가로드(15)의축방향으로다수장착되어구성되는지중강관다중변형장치및 이를이용한강관말뚝단면확장공법으로서, 지반에관입된강관(10) 내부로지중강관다중변형장치를투입한후 가동하여강관(10)에다중변형부(11)하고, 강관(10) 내부에콘크리트를타설하여합성강관말뚝을형성하는것이다. 본발명을통하여, 강관(10)이지반에관입된상태에서강관(10)의단면을확장할수 있으므로합성강관말뚝의지지력을획기적으로증대할수 있을뿐 아니라, 기존노후구조물의보강, 시설물하부지하공간의확장및 뜬구조역타공법등 대구경지상굴착에제한이있으면서도강관말뚝에대한고도의지지력발현이요구되는공사에있어서특히우수한효과를얻을수 있다.
摘要（英）：

The present invention relates to a multi-shape changing apparatus for an underground steel pipe, wherein a plurality of diameter expansion bodies (20) stretched in a direction perpendicular to a steel pipe (10) inserted into the ground and a plurality of compression bodies (30) installed on ends of the diameter expansion bodies (20) to be moved in a direction perpendicular to the steel pipe (10) as the diameter expansion bodies (20) are stretched are mounted on a rod (15) supplied to the steel pipe (10) in an axial direction of the rod (15), and a steel pipe pile cross section expansion method using the same. The multi-shape changing apparatus for an underground steel pipe is supplied into a steel pipe (10) inserted into the ground and is then operated to have a multi-shape changing unit (11) on the steel pipe (10), and concrete is deposited in the steel pipe (10) to form a synthetic steel pipe pile. The present invention can expand the cross section of the steel pipe (10) while the steel pipe (10) is inserted into the ground to drastically increase the support power of the synthetic steel pipe pile, and obtain a particularly excellent effect in construction requiring high-level support power realization for the steel pipe pile while having limitations on large hole ground excavation such as a floating structure top-down method, expansion of an underground space under a facility, and reinforcement of an existing decrepit structure.COPYRIGHT KIPO 2022
