The present invention relates to an excavating rod connection band of a ground excavating device for constructing a slurry wall used for a soil cement wall (SCW) method. In the excavating rod connection band which ties up multiple excavating rods to be able to rotate and maintain a constant distance so a ground excavating operation is progressed while the excavating rods maintain the constant distance when an excavating operation is progressed by connecting the excavating rods on each lower end of multiple connection rods one by one to construct the slurry wall by using a ground excavating device comprising: an auger drive unit installed to be able to perform an elevating operation upward and downward along a leader; a gear box which is located on the lower side of the auger drive unit and mounts a reduction gear device capable of reducing rotary power received from the auger drive unit; and the connection rods which are connected to the gear body in the lower side, the excavating rod connection band includes; multiple circle units to surround and hold each of the excavating rods to be able to rotate; one or more connection units to connect the circle units; and multiple forced excavating wings wherein multiple protruding wings which are symmetrically protruding from both sides of each of the circle units and multiple connection wings to connect the end of the protruding wings are symmetrically formed. |
