SENSOR FOR SCP METHOD, CASING PIPE FOR SCP METHOD, SAND PILE SHAPE EVALUATION METHOD, AND CONSTRUCTION MANAGEMENT METHOD FOR SCP METHOD

摘要

To provide a sensor for an SCP method that can evaluate and confirm a shape of a sand pile in real time during construction by a sand compaction pile method (SCP method), a casing pipe for the SCP method having this sensor, a method for evaluating the shape of the sand pile using this sensor and a construction management method for the SCP method.SOLUTION: A sensor 20 for the SCP method includes a plurality of electrodes 21 to 24 arranged in a longitudinal direction on an outer peripheral surface 10b of a lower part of a casing pipe 10 for the SCP method, the plurality of electrodes is provided so as to contact an interior of a sand pile SC to be created on the ground by the casing pipe, measures the specific resistance value at a predetermined measurement distance c of the lateral sand pile side from the outer peripheral side of the casing pipe, and evaluates the shape of the sand pile on the basis of the measured specific resistance value.SELECTED DRAWING: Figure 1
