The movement of the mapping support 3 is limited by the limiting rod 16, so that when the mapping support 3 pauses to move and is ready to accept compression detection, the mapping support 3 is positioned right below the pressing plate 22, and detection in the sand simulation area 11 is taken as an example: when the surveying and mapping support 3 is driven by the annular runway conveyor 14 to move leftwards, the surveying and mapping support 3 pauses to move when the middle part of the surveying and mapping support 3 is in contact with the limiting rod 16 for the first time, the surveying and mapping support 3 is located right below the pressing plate 22 on the rightmost side, when the pressing plate 22 moves downwards, the gear 145 is driven by the motor 144 to intermittently rotate, the gear 145 is meshed with the annular rack 143 so that the annular rack 143 drives the annular plate 141 and the limiting rod 16 to integrally move, the limiting rod 16 moves leftwards, the gear 145 rotates for two circles to pause to rotate, the limiting rod 16 is located on the left side of the pressing plate 22 in the middle, then when the surveying and mapping support 3 continues to move to contact with the limiting rod 16 on the position, the surveying and mapping support 3 is just opposite to the pressing plate 22 in the middle, after the surveying and mapping support 3 completes detection in the sand simulation zone 11, the limiting rod 16 is reset, the surveying and mapping support 3 completing detection in the sand simulation zone 11 is manually moved into the soil simulation zone 12, and the new surveying and mapping support 3 is placed in the sand simulation zone 11. The center of the mapping bracket 3 and the center of the pressing plate 22 are located on the same axis through the limiting of the limiting rod 16, so that the pressure of the hydraulic cylinder 21 in the pressing process always presses the center of the mounting circular plate at the upper end of the mapping bracket.

When the height of the surveying and mapping support 3 changes, the height of the stop lever 162 is changed through the threaded telescopic rod 161, so that the stop lever 162 is always positioned at the middle section of the surveying and mapping support 3, and the phenomenon that the gravity center of the surveying and mapping support 3 is unstable due to the fact that the position of the stop lever 162 is low is avoided.
Referring to fig. 8, a scale riser 163 fixedly connected to the upper end of the annular rack 143 is disposed on one side of the threaded telescopic rod 161.
When the height of the mapping bracket 3 is changed, the total length of the threaded telescopic rod 161 can be accurately adjusted by using the scale vertical plate 163, so that the height of the stop rods 162 can be adjusted, and the same height position of all the stop rods 162 can be ensured.
Referring to fig. 4, a round bar 221 is installed at the center of the lower end of the pressing plate 22.
