However, the geographical environment in some areas is very complex. For example, in coastal environments such as ports, bridges, and coastal defenses, it is necessary to use ships to carry out the exploration work. Therefore, amphibious exploration platforms are created to meet the needs of exploration work in different environments.

8. The amphibious geotechnical engineering survey platform according to claim 6, characterized in that: The work platform (1) is provided with gap shielding plates (14) on opposite sides. When the extension section (5) is turned to be horizontal, the side of the gap shielding plate (14) close to the walking module (3) is in contact with the upper surface of the mounting portion (51).

9. The method for using the amphibious geotechnical engineering survey platform according to any one of claims 1 to 8, characterized in that: The following steps are involved: S1. Land operation: Move the survey platform to the scheduled survey operation site through the walking device; S2, water area operation: the survey platform is floated on the water surface by means of the buoyancy device (2), and the position of the survey platform on the water surface is adjusted by means of the propulsion module (4) so ​​as to reach the predetermined operation location; S3. Adjusting the platform working area: The two extension sections (5) are driven by the driving device (6) to rotate to a horizontal position, thereby expanding the area of ​​the working platform (1); the two extension sections (5) are driven by the driving device (6) to rotate to a vertical position, hidden under the working platform (1) without hindering the movement of the working platform (1).
