4A is a partial cross-sectional view schematically illustrating a state in which a casing tube is pressurized into the ground using an oscillator or a rotator, and FIG. 4B is a casing tube using the crane according to the present invention. Figure 4c is a schematic partial longitudinal cross-sectional view showing a state seated inside, Figure 4c is a schematic partial longitudinal cross-sectional view showing a state of fixing the complex drilling rig according to the present invention to the casing tube using a clamper, Figure 4d FIG. 4E is a schematic partial longitudinal cross-sectional view showing a state of excavation and soil storage using the composite excavation device according to the present invention, and FIG. .

The construction method using the composite drilling rig includes a casing tube 510 press-fit step of pressing the casing tube 510 into the ground as shown in FIGS. 4A to 4E, and the composite drilling rig is inserted into the casing tube 510. Complex excavator mounting step for seating, using a clamper 140 of the complex excavator device complex excavator fixing step for fixing the complex excavator in the casing tube 510, drive unit 30 of the complex excavator The excavation and excavation storage step of operating the motor 320 and the pressurizing cylinder 210 to store the excavation and excavation soil into the capsule pipe 440, and the complex excavation device out of the casing tube 510. It is characterized in that it comprises a top-up step to discharge the excavated soil in the capsule pipe (Capsule Pipe) (440).

The casing tube 510 press-fit step is to press the casing tube 510 into the ground as shown in Figure 4a, using the oscillator or rotator 530, etc. to rotate or swing the casing tube 510 in the ground Press in.

Since all casing excavators 530 and the like are used as base machines, bending of the hollow walls is difficult to occur, and various auxiliary excavators can be utilized.

The complex excavator mounting step is to seat the composite excavator in the casing tube 510, as shown in Figure 4b, by using a crane to the composite excavator connected to the main wire 520 of the crane It lifts up and slowly descends in the casing tube 510 to seat the bit 430, which is the tip of the screw of the complex excavator, on the floor.

The fixing of the complex excavator is a step of fixing the excavator in the casing tube 510 using the clamper 140 of the excavator as shown in Figure 4c, the fixing part of the complex excavator ( When the clamp cylinder 130 of 10 is inflated, the movable piece 140a inclined at a predetermined angle connected to the cylinder rod 130a of the clamp cylinder 130 is moved upwards, and thus the movable fixing piece is moved left and right. While ascending, pushing the inside of the casing tube 510 fixes the complex excavator in the casing tube 510.

In the excavation and excavation storage step, as shown in FIG. 4D, the excavation and excavation soil is operated by operating the motor 320 and the pressure cylinder 210 of the driving unit 30 of the complex excavation device. 440, the motor 320 is rotated by driving the motor 320 of the driving unit 30 of the complex drilling rig and simultaneously expanding the pressure cylinder 210 of the pressing unit 20. Accordingly, while the connector 330, the screw 410, and the bit 430 interlocked with the motor 320 rotate, the screw 410 and the bit 430 are predetermined downward by the cylinder of the pressing unit 20. Underground pressure is excavated while pressing.

Since the rotation of the screw 410 and the bit 430 is a hydraulic drive by the hydraulic motor 320, the impact drilling is not performed, thereby reducing noise and vibration and reducing the variation of the engine load.

In the case of deep depth excavation such as the Earth Auger method, the weight of the screw rod or the required rotation torque is increased, and the motor 320, which is the driving unit 30, is located at the top of the rotating shaft so that the center of gravity is located. Although the safety is insufficient due to the high risk of falling, etc., when the excavation construction is carried out by the above-described complex excavation device, the underground excavation device performs excavation in the casing tube 510 even when deep depth excavation is performed. Therefore, not only the torque is minimized, but also the center of gravity is low, thus eliminating the risk of falling, such as safe construction.

In addition, since the drilling of the screw is performed by the sufficient pressing force by the pressurizing cylinder 210 and the sufficient rotating force by the hydraulic motor 320, it is not necessary to use the water, such as water, in a general construction. There is no need.

The excavated excavated soil as described above is moved to the upper side of the screw is contained by the screw rotated in the capsule pipe 440.

The topsoiling step is to lift the underground drilling rig out of the casing tube 510 as shown in FIG. 4E, and then discharge the drilled soil in the capsule pipe 440 to the fixing part 10 of the complex drilling rig. After the clamp cylinder 130 is compressed and released from the clamper 140, the composite excavator is pulled out of the casing tube 510 by a crane, and the screw 410 is rotated backwards into the capsule pipe 440. Drain the excavated pit.

The amount of excavation excavation is close to the capacity of the capsule pipe 440, and the excavation excavation volume is about 5 to 10 times larger than that of the hemer grab. This can be greatly improved, and this advantage is more pronounced at deeper excavation depths. Therefore, the rapid construction and excavation construction costs can be greatly reduced.

In the excavation method using the complex excavation device, the complex excavation device release step of releasing the clamper 140 in the casing tube 510 between the excavation and the clay storage step and the clay discharging step; A composite excavator mounting step for seating the composite excavator in the casing tube 510 and a composite excavator for fixing the composite excavator in the casing tube 510 using the clamper 140 of the composite excavator. It is preferable to include a fixing step.

If the stroke length of the pressurized cylinder 210 and the height of the capsule pipe 440 are not significantly different, after one excavation and topdressing storage step, the complex excavation apparatus may be lifted out of the casing tube, and then the topdressing efficiency may be improved. In order to maximize, it is preferable to increase the capacity of the capsule pipe 440.

Therefore, since the excavation soil is not filled in the capsule pipe 440 by one excavation and excavation storage step, excavation and excavation storage in consideration of the stroke length of the pressurized cylinder 210 and the capacity of the capsule pipe 440. It is desirable to establish the number of steps.

The compound excavator release step is a step of releasing the clamper 140 from the casing tube 510 to the complex excavator as shown in Figure 5a, the complex excavator is suspended on the main wire 520 of the crane In this state, the clamp cylinder 130 is compressed to release the clamper 140 from the casing tube 510.

The complex excavator mounting step is to seat the complex excavator in the casing tube 510, as shown in Figure 5b, by using a crane to the composite excavator connected to the main wire 520 of the crane The bottom of the casing tube 510 is gradually lowered to seat the bit 430, which is the tip of the screw of the complex excavator, on the bottom.

The fixing of the complex excavator is a step of fixing the excavator in the casing tube 510 using the clamper 140 of the excavator as shown in Figure 5c, the fixing part of the complex excavator ( Inflating the clamp cylinder 130 of 10) the moving piece 140a inclined at a predetermined angle connected to the cylinder rod 130a of the clamp cylinder 130 is moved upwards and thus the moving fixing piece 140b. (C) is fixed to the casing tube (510) while pushing the inside of the casing tube (510) while rising to the left and right.

As described above, the complex excavation device and the excavation method using the same greatly increase the amount of excavation, thereby reducing the number of excavations, minimizing noise and vibration, and eliminating the risk of cutting due to the impact of the main wire connected to the crane. In addition, there is an effect that can be efficiently excavated even in hard ground and sand gravel ground.

And even when deep depth excavation is maintained, the top efficiency is minimized, the rotation torque is minimized, there is no risk of turning the rotating mechanism, etc. It is excellent in compatibility, such as being able to use an excavation device, there is no need for a large amount of water treatment device, there is another effect that can improve productivity with fast construction.
