[0027] When the drilling machine 8 is fixed in place, the installation of the standard drill rod 809 is carried out. The motor 801 and the propulsion drill rod 808 are lifted by the hydraulic cylinder 804, the drilling drill rod 810 is hung on the drill rod clamp plate 813, then the first standard drill rod 809 is installed on the drilling drill rod 810, the hydraulic cylinder 804 is adjusted, the upper propulsion drill rod 808 is connected with the first standard drill rod 809, the drill rod clamp plate 813 is reset after the first drill rod joint 811 passes through the drill rod supporting plate 812, the drill rod is continuously lowered, until the second drill rod joint is clamped on the drill rod clamp plate 813, then the connection between the propulsion drill rod 808 and the second drill rod joint is released, the motor 801 and the propulsion drill rod 808 are lifted, and the above steps are repeated to install the next standard drill rod 809. When the drill rod is long enough to reach the river bottom rock, the drilling machine is started to drill, and as the drilling depth increases, the above steps of lengthening the drill rod are continued to increase the standard drill rod.

[0028] Based on the above embodiment, both ends of the ship body truss 2 are fixedly connected with the ship box body 1, wherein the ship body truss 2 is a hollow steel beam structure, ensuring that the middle part of the ship body is hollow, and the drill rod can extend downward in the ship body truss 2; due to the multiple gaps in the ship body truss 2, the drill rod can extend downward in the ship body truss 2 to drill holes, further increasing the applicable range, that is, the device is not only limited to drilling holes on both sides of the ship body, but also can drill holes directly below the ship body.

Loosen the drill rod clamp plate 813, adjust the hydraulic cylinder 804 to lower the drill rod, and after the first drill rod joint 811 passes through the drill rod support plate 812, the drill rod clamp plate 813 is reset and fixed, and the drill rod continues to be lowered until the second drill rod joint is clamped on the drill rod clamp plate 813, then the connection between the pushing drill rod 808 and the second drill rod joint is released, the lifting motor 801 and the pushing drill rod 808 are lifted, and the above steps are repeated to install the next section of the standard drill rod 809. After the drill rod is lengthened to the rocks at the bottom of the river, the drill is started to drill, and as the drilling depth increases, the above drill rod lengthening steps are continued to increase the standard drill rod when the drill rod length is not enough.

[0032] After drilling to the designed depth, the drill rod is lifted, and then the drill 8 is moved to the next hole position to continue drilling operation. When the drill rod needs to be removed, the hydraulic cylinder 804 is reciprocated to lift and cooperate with the drill rod clamp plate 813 to remove the drill rod section by section.

[0033] After each hole is drilled, the drill rod is lifted, the underwater camera is used to find the drilling position along the drill rod, and then the drill 8 is moved.
