CAISSON CONSTRUCTION MANAGEMENT DEVICE AND CAISSON CONSTRUCTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a construction management device that displays an excavation situation of an inner bottom surface of a caisson skeleton with good visibility in order to support operation of an operator, and can help decision of the operation by visually transmitting a current progress situation.;SOLUTION: A construction management device is used when constructing a caisson of a necessary depth. The construction management device includes a GPS antenna 16, a GPS receiver 15, a main winding sensor 11 and an auxiliary hoist sensor 12. In addition to them, the construction management device includes an excavation position arithmetic processing unit 17 for finding a three-dimensional position of a bucket 13 at the time when the bucket 13 performs landing in an inner bottom surface of a caisson skeleton 1, and a display monitor 18 for displaying the depth of each part of every one excavation operation of the bucket 13 in the inner bottom surface of the caisson skeleton 1 under excavation in association with a projection shape of the caisson skeleton 1.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2017,JPO&INPIT
