[0020] See also Figure 1-4 The utility model provides a technical solution: a measuring device for geotechnical engineering investigation, comprising a mobile frame 1 and an infrared measuring instrument 2. Adjustment slots 12 are respectively provided on both sides of the top of the mobile frame 1, clamping plates 3 are movably installed on both sides of the top of the mobile frame 1, and through plates 4 are respectively connected to both sides of the mobile frame 1.

[0022] The movable frame 1 moves to the survey and measurement base point through the bottom roller, and when the output end of the driving motor 5 drives the longitudinal screw rod 7 to rotate, the adjusting plate 8 in the through plate 4 can drive the bottom conical embedded block 81 to embed into the ground on both sides of the base point under the thread cooperation of the longitudinal screw rod 7, so as to realize the positioning of the movable frame 1, and the second conical gear 71 outside the longitudinal screw rod 7 transmits the first conical gear 61 at the end of the transverse screw rod 6 on the same side, so that the transverse screw rod 6 can be driven synchronously, and the bottom adjusting block 31 of the clamping plate 3 can clamp and position the infrared measuring instrument 2 under the thread cooperation of the transverse screw rod 6, so that when measuring the geotechnical survey base point, the movable frame 1 and the infrared measuring instrument 2 can be synchronously positioned at the base point.
