摘要：PROBLEM TO BE SOLVED: To provide a method for constructing an underground wall, capable of efficiently forming the underground wall in a cavity part existing underground.SOLUTION: A pipe body 9 and a bag body 7 are inserted into a drilling hole 3. Then, a filler is sent into the bag body 7 by pressure via the pipe body 9. The bag body 7 is expanded by the filler inside the cavity part 5. For example, the bag body 7 is expanded into a diameter larger than that of the drilling hole 3. For example, the filler is a grout material. In this case, it is preferable that adjoining bag bodies 7 are made to come into tight contact with each other. Moreover, it is preferable that the bag body 7 and the inside surface of the cavity part 5 are made to come into tight contact with each other. Thereby, an underground wall 10 having a high closing characteristic to the cavity part 5 can be constructed.
