Construction management manner of soil improvement construction method and quality of soil configuration and

摘要

PROBLEM TO BE SOLVED: To provide a construction work management method for a soil improving construction method, and also to provide a processing machine for soil improvement.;SOLUTION: Test construction work for excavation/intrusion by using a processing machine 1 for soil improvement is performed at a position close to a boring data sampling position for providing clear soil composition. N-value data, etc. of a construction place to sample each of intrusion speed, intrusion depth, hours required for intrusion, a load torque value or a load current value of an electric motor being a power source for intrusion of the processing machine 1 for soil improvement, and an excavation resistance value at excavation time in the test construction work by using the processing machine 1 for soil improvement, are gatherered every intrusion depth until the intrusion reaches a supporting layer made clear by the boring data. Each of an estimated depth at the sampled supporting layer reaching time, an estimated load torque value or an estimated current value of the electric motor at the supporting layer reaching time, an estimated intrusion speed at the supporting layer reaching time, and an estimated excavation resistance value at the supporting layer reaching time is adopted as reference values for determining reaching at the supporting layer to carry the construction work after this according to the soil improving construction method forward in order from an adjacent position.;COPYRIGHT: (C)2008,JPO&INPIT
