Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a low-cost filling method capable of limitedly filling an arbitrary region in an underground hollow C regardless of the presence/absence of groundwater and facilitating the construction. SOLUTION: The outer circumference of a filling region of the underground hollow C is closed by filling a relatively low-fluidity gelled outer circumference filling material 1 and a fill filling material 2 having initial fluidity relatively higher than the outer circumference filling material 1 fills a space in its internal circumferential side. The outer circumference filling material 1 is composed of water glass, a cement based solidification material, a soil material and water, and gelated by continuously merging and mixing first filling liquid 10 including water glass with second filling liquid 20 including the cement based solidification material in a feed process to the underground hollow C and the initial fluidity of the outer circumference filling material 1 is controlled by the mixing rate of the components.
