Some embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without conflict.

Examples:

as shown in fig. 1, the soil layer investigation apparatus provided in the present embodiment includes a vehicle body 1, a shearing assembly 2, a pressurizing assembly 3, a pressure detection assembly, a camera assembly and a control assembly 4; the pressurizing assembly 3 is arranged on the vehicle body 1, the shearing assembly 2 and the pressure detecting assembly are connected with the pressurizing assembly 3, the shearing assembly 2 is used for ascending or descending under the drive of the pressurizing assembly 3 so as to drill or drill into a plurality of soil layers of the soil body, and the pressure detecting assembly is used for detecting the pressure applied by the pressurizing assembly 3 to the shearing assembly 2; the vehicle body 1 comprises a driving system, the driving system of the vehicle body 1 and a camera shooting component are connected with a control component 4, the camera shooting component is used for scanning scenes on the periphery of the vehicle body 1 and sending scene information to the control component 4, and the control component 4 is used for planning a running path of the vehicle body 1 according to the received scene information and controlling the driving system to work so as to enable the vehicle body 1 to move along the running path.

When the soil layer investigation device provided by the embodiment is used for carrying out geotechnical engineering geological investigation on a construction area, the vehicle body 1 of the soil layer investigation device can be placed in the construction area, then the camera shooting assembly is started, and the camera shooting assembly is used for scanning the scene on the current vehicle body 1 circumference side and sending scene information to the control assembly 4. After receiving the scene information sent by the camera shooting component, the control component 4 can automatically plan a driving path of the vehicle body 1 according to the scene information, and it is required to be noted that the driving path is located in a construction area range and a parking point can be arranged at intervals according to preset intervals so as to facilitate soil layer investigation, and according to the information sent by the camera shooting component, the driving path can effectively avoid obstacles, so that the vehicle body 1 can smoothly move from one side of the construction area to the other side.

After the control component 4 generates the running path of the vehicle body 1, the driving system of the vehicle body 1 is controlled to work based on the running path, so that the vehicle body 1 automatically moves along the running path, and in the process, the vehicle body 1 is driven to move without manually arriving at the site, thereby reducing the labor intensity and improving the construction efficiency.

The vehicle body 1 may also be temporarily stopped from moving during the movement of the vehicle body 1 along the travel path to survey each soil layer of the soil body therebelow. Specifically, when the vehicle body 1 moves along the travel path by a preset distance, the control component 4 controls the driving system to stop working, then the vehicle body 1 is suspended, then the pressurizing component 3 is started, and the pressurizing component 3 is used for driving the shearing component 2 to descend and drill into soil below the shearing component.

When the shearing assembly 2 sequentially drills all soil layers, the pressure detection assembly can detect a plurality of pressure values in real time, and the pressure values detected by the pressure detection assembly in real time are approximately equal to the soil layer resistance, so that when the control assembly 4 receives the pressure information sent by the pressure detection assembly, the control assembly 4 can automatically compare the pressure information with the comparison table, and the type of the soil layers drilled by the shearing assembly 2 is judged.

It can be seen that when the pressure detection assembly is connected with the control assembly 4 and the control assembly 4 is preset with a plurality of resistance parameters corresponding to various soil layers one by one, the control assembly 4 can automatically judge the soil layer types according to the pressure information detected by the pressure detection assembly and the preset soil layer resistance and soil layer type comparison table without manual comparison, so that the working efficiency and the use convenience of the soil layer investigation device are effectively improved.
