The bottom of the strip-shaped row drilling assembly is positioned through the cuboid positioning sleeve 14. The strip-shaped row drilling assembly moves up and down along the profiled steel track driven by the winch 4. An electronic vertical display 16 is arranged on the side of the main tower 12. A crawler chassis 2 and a plurality of hydraulic outriggers 9 are arranged at the bottom of the drilling rig rotating platform 1. The electric energy generated by the generator set 3 is distributed to the hydraulic pump station 6, the winch 4, the electronic vertical display 16, and the crawler chassis 2 through the power distribution cabinet 5. The main rod hydraulic cylinder 7, the strip-shaped row drilling assembly, and the hydraulic outriggers 9 are all connected to the hydraulic pump station 6. The present invention can not only generate electricity by the generator set, but also distribute electricity at the construction site. The present invention is applicable to the deep foundation pit support of assembled precast shuttering plates. Most of the accessories required for the equipment are market standard accessories. The equipment is simple to process and assemble, convenient to operate, the quality can be controlled, and mass production can be carried out.

[0024] Specifically, the strip-shaped row drilling assembly includes a long spiral drill rod 17, a hydraulic power head 13 and a wall-repairing slicer 19. The top of the long spiral drill rod 17 is connected to the output shaft of the hydraulic power head 13. The bottom of the long spiral drill rod 17 is connected with a thickened drill bit 20. The wall-repairing slicer 19 is arranged at the bottom of the long spiral drill rod 17. The wall-repairing slicer 19 is connected to the hydraulic power head 13 through a plurality of vertical partition steel plates 18. The plurality of vertical partition steel plates 18 form a row-shaped cavity body. The long spiral drill rod 17 is arranged inside the row-shaped cavity body. The thickened drill bit 20 extends below the wall-repairing slicer 19. The hydraulic power head 13 is connected to the hydraulic pump station 6. Specifically, the numbers of the long spiral drill rod 17 and the hydraulic power head 13 are both set to four and arranged side by side. The number of the vertical partition steel plates 18 is set to five. The present invention drills holes through the strip-shaped row drilling assembly. A plurality of long spiral drill rods 17 drive the thickened drill bits 20 to work simultaneously, directly machining out long strip rectangular holes, simplifying the drilling process, saving time and effort, and improving work efficiency.

[0025] The bottom of the wall-repairing slice 19 is provided with an inclined cutting edge, and the cross-section of the wall-repairing slice 19 is set as a rectangle; by arranging the wall-repairing slice 19, the soil around the drill hole can be vertically cut, and the trimming work of the inner wall of the long strip rectangular hole can be completed while drilling, so as to ensure that the processed long strip rectangular hole meets the requirements of later construction.

[0026] The diameter of the thickened drill bit 20 is larger than the diameter of the long auger stem 17, and the diameter of the thickened drill bit 20 is equal to the minimum side length of the wall-repairing slice 19.

[0027] Three stiffening steel strips 15 are arranged in the middle of the strip-shaped row drill assembly to ensure the positions of the plurality of long auger stems 17 are fixed, prevent the positions of the long auger stems 17 from changing during the working process, and affect the drilling accuracy.

[0028] The number of the first supports 10 is set to two, and the two first supports 10 are symmetrically arranged on one side of the rotary platform 1 of the drill rig. On the side of the rotary platform 1 of the drill rig away from the first supports 10, there are second supports 11, and the number of the second supports 11 is set to two and they are symmetrically arranged; when the drill rig is not working, the main tower 12 is horizontally placed above the first supports 10 and the second supports 11, which is convenient for the movement of the drill rig.

[0029] The number of the hydraulic legs 9 is set to four, and the four hydraulic legs 9 are symmetrically arranged at the four corners of the bottom of the rotary platform 1 of the drill rig; when the drill rig is working, the hydraulic legs 9 play a role of positioning and supporting.

[0030] The using process of the present invention is as follows:

[0031] Step 1: Drive the drill rig through the crawler chassis 2 to move the drill rig to the construction site; Step 2: Start the generator set 3 to generate electricity and distribute power through the power distribution cabinet 5; Step 3: Start the hydraulic pump station 6 and adjust the hydraulic outriggers 9 to lower the hydraulic outriggers 9 to the ground to complete the support of the drill rig; Step 4: The main rod hydraulic cylinder 7 works to erect the main tower 12, adjust the angle of the main tower 12, and at the same time observe through the electronic vertical display 16 until the main tower 12 reaches the vertical position, then turn off the main rod hydraulic cylinder 7; Step 5: Start the hydraulic power head 13 and the winch 4. The strip drill assembly moves downward along the profiled steel track driven by the winch 4. The hydraulic power head 13 drives the long auger drill rod 17 and the thickened drill bit 20 to rotate vertically downward for drilling. The drilled soil enters the row cavity body and is discharged upward by the rotation of the blades of the long auger drill rod 17. The wall repair slicer 19 vertically cuts the soil around the drill hole relying on the self-weight of the hydraulic power head 13, the row cavity body and the long auger drill rod 17, squeezes the soil into the blades of the auger drill rod 17, and discharges the drilled soil upward through the rotation of the auger drill rod 17 until the required depth is drilled; Step 6: Turn off the hydraulic power head 13, lift the strip drill assembly by the winch 4, adjust the hydraulic outriggers 9 to lift the hydraulic outriggers 9 until they are away from the ground, start the crawler chassis 2, and the crawler chassis 2 drives the drill rig to move to the next working position. Repeat Step 5 above to drill long rectangular holes step by step according to the required support position; Step 7: After drilling long rectangular holes at the required positions, the winch 4 lifts the strip drill assembly, and the main rod hydraulic cylinder 7 works to drive the main tower 12 to the horizontal position so that the upper end of the main tower 12 supports on the second support 11. Adjust the hydraulic outriggers 9 to lift the hydraulic outriggers 9 until they are away from the ground, start the crawler chassis 2, and move the drill rig away; Step 8: Hoist and install the support plate at the long rectangular hole to complete the installation and hoisting work of the deep foundation pit support plate.
