Title:
IMPROVEMENT DIAMETER MEASUREMENT DEVICE
Document Type and Number:
Japanese Patent JP2013072747
Kind Code:
A
Abstract:
To improve detection accuracy in improvement diameter measurement.
An improvement diameter measurement device includes a detection device 10 which has a switch body 12b and a distal end part 12a capable of approaching and separating from the switch body 12b, detects a prescribed position pressurized by the distal end part 12a being abutted to an unimproved soil of a boundary surface, and is fixed to a distal end of an extendable measurement body 6 in a long-length rod shape curved in a cross-sectional view. By extending the detection device 10 in a radial direction of an improvement body as the measurement body 6 is sent out, a radial dimension of the improvement body is measured.
