[0015] See also Figure 1 , a survey device for the early stage of three-dimensional geological modeling in this embodiment can adjust the length of the supporting rods on both sides of the spiral drill rod according to the actual terrain, so that the spiral drill rod can remain in a vertical state when drilling, reduce the probability of deviation, and improve the survey efficiency. It mainly includes a base frame 1 and a lifting mechanism and a drilling mechanism installed on the base frame 1. The base frame 1 is a door-type frame. A walking wheel 16 is installed at the lower end of the base frame 1 to facilitate the transfer of the survey device. A handrail 15 is arranged at the upper end of the base frame 1. A level is placed on the base frame 1 to facilitate the adjustment of the drilling angle of the spiral drill rod.

[0016] The lifting mechanism includes an electric telescopic rod 6, a base 3 and a guide wheel group 5. The two ends of the base 3 are slidably connected to the base frame 1 through the guide wheel group 5. Through grooves are provided on the two side panels of the base frame 1, and parallel slide rails 2 are provided on both sides of the through grooves. The two groups of guide wheels on the guide wheel group 5 are respectively in contact with the slide rails 2 on both sides of the through grooves to guide the base 3 to move up and down along the side panels of the base frame 1. The two ends of the electric telescopic rod 6 are respectively connected to the top plate of the base frame 1 and the base 3 to control the relative movement between the base frame 1 and the base 3, and then control the relative height of the walking wheel and the spiral drill rod.

[0017] The drilling mechanism includes an auger rod 13 and a support rod 14, the support rod 14 is arranged on both sides of the auger rod 13, a plug 10 is arranged at the lower end of the support rod 14, the plug 10 is in contact with the ground, the upper part of the support rod 14 is fixedly connected to the slide rod 7 by bolts, the middle part of the slide rod 7 is slidably connected to the base 3 and the slide groove 9, a connecting rod 8 is arranged between the upper ends of the two oppositely arranged slide rods 7, so that the two support rods 14 keep moving synchronously, the auger rod 13 is installed below the base 3 through a motor 12, and fixed frames 11 are arranged on both sides of the motor 12 for supporting the motor and the auger rod.

[0018] When in use, after arriving at the survey site, use the walking wheels to move the survey device to the designated position, and stand up the survey device. According to the flatness of the ground and the drilling angle, adjust the distance between the two plugs and the ground so that when the two plugs are in contact with the ground, the angle of the auger rod remains the same as the drilling angle. The electric telescopic rod is extended to control the support rod and the auger rod to descend until the walking wheels leave the ground. The motor drives the auger rod to start drilling. During the drilling process, keep the two plugs in contact with the ground at the same time to ensure the accuracy of the drilling angle and avoid deviations that affect subsequent surveys.
