CONSTITUTION: A construction method of a block type underground grout structure including vacuum drain hole formation and grout injection direction control by vacuum drainage is as follows. Injection holes(10) and vacuum drain holes(20) are bored at certain intervals in the ground. The vacuum drain holes are made into vacuum state while injecting grout into the injection holes, thereby leading the grout injected into the injection holes toward the vacuum drain holes. Bulbs are formed by the grout which flows from the injection holes toward the vacuum drain holes. Grout is injected in the vacuum drain holes so that an underground grout structure is formed.
