| A three-axis ground excavating apparatus for GCM(Gravel Cement Mixing) method is provided to prevent concentration of gravels during improving of soft ground and construction of underground vertical waterproof wall, and to execute a uniform grouting by equally mixing gravels distributed in soil. A three-axis ground excavating apparatus for GCM(Gravel Cement Mixing) method comprises a crawler crane, a leader, an auger, a three-axis gear box(4), and a three-axis rod. The crawler crane automatically moves on the ground, moving the three-axis rod to an excavation point. The leader is vertically secured on the ground by a support arm and a backstay provided on a distal end of the crawler crane, guiding lifting movement of the auger. The auger, as a power source to rotate the three-axis rod, is lifted along two guide bars that are secured in parallel perpendicular to the leader for intrusion of the three-axis rod underground and for drawing out therefrom. The three-axis gear box, mounted on a lower side of the auger, to rotate the three-axis rod by torque transmitted by the auger. Inside the three-axis gear box, one driving rotary axis(4a) rotatably mounted in the center, and two linked rotary axes(4b,4c) rotatably mounted on the opposite sides of the driving rotary axis, are disposed in a line having predetermined intervals therebetween. The three-axis rod, comprising one driving rod(5a) and two linked rods(5b,5c), is provided to excavate ground and mix the excavated soil and gravels. The driving rotary axis and two linked rotary axes rotate in the same direction, so that the driving rod and linked gears that are connected at lower ends of each rotary axis rotate in the same direction for excavation and mixing operations. | ||||||
