The present invention relates to an excavation rod connection band of a ground excavation device for slurry wall construction used in a soil cement wall (SCW). In order to excavate the ground in a state where multiple excavation rods are always separated from each other at a predetermined interval when an excavation operation is performed by connecting the excavation rods to multiple connection rods for the construction of slurry walls using a ground excavation device having an auger drive unit installed in a leader, a gear box installed in the lower part of the auger drive unit, and the multiple connection rods connected downward in the gear body in multiple stages, an excavation rod connection band holds the excavation rods to maintain the predetermined gap while rotating the excavation rods. The excavation rod connection band comprises: multiple circular parts to hold the excavation rods while surrounding the excavation rods to be rotated; one or more connection parts to respectively connect the circular parts; and a forcible excavation wing having multiple front and rear protrusion wings symmetrically protruding forward and backward from both sides of the circular parts, front and rear connection wings formed in parallel to each other to connect the end of the front and rear protrusion wings, and left and right semi-circular wings extended from both ends of the front and rear connection wings to surround the excavation rods. |
