Japanese Patent JP6663324

B2

PROBLEM TO BE SOLVED: To enable monitoring of groundwater at an inner part of a hole.SOLUTION: A boring hole 4 is formed by drilling with a first pipe (a drilling pipe) 3 having a drilling unit 2 (including a drilling bit 2a) fitted at a tip, and then a first pipe 3 is retracted. A second pipe (an intake pipe) 8 having a packer 9 on outer periphery at a tip part is inserted into the first pipe 3, and the drilling unit 2 is removed by pushing to have the tip part of the second pipe 8 protrude from a tip surface of the first pipe 3. The packer 9 is expanded to have an outer peripheral surface of the packer 9 adhered closely on an inner peripheral surface of the boring hole 4. Groundwater is taken from inside the second pipe 8, to measure water pressure or a flow amount.SELECTED DRAWING: Figure 1
