Abstract

PURPOSE: To insert a measurement instrument under a reduced frictional force by pulling out a tape as a self-boring type measurement instrument is inserted and by covering an outer circumferential surface of the measurement instrument with the pulled out tape.
CONSTITUTION: Downward force is applied to an outer pipe on the ground with respect to the measurement instrument 1 descended in the hole bottom 4a of the boring hole 4 and the outer pipe is pushed into the ground, and at the same time the boring rod 2 is rotated and the cutter 3 is rotated. Pressurized water is injected from the leading end of the cutter 3 to break the soil inserted into the front casing 6, the soil is discharged out of the ground to perform a self-boring and then the measuring instrument 1 is pressed into the ground. In this case, when the measuring instrument 1 is inserted into the ground from a position of the hole bottom 4a, the annular tape lipper 9 fitted on the pipe is left on the hole bottom 4a. As the measuring instrument 1 is inserted, all the tapes 7, 7...are pulled out of each of the magazines 8, 8.... As a result, the tapes 7, 7...cover the outer circumferential surface of the measuring instrument 1 to eliminate or prevent a contact between the outer circumferential surface and the earth, thereby no friction is generared.
