The shock absorption effect of the buffer platform is not very good, which cannot meet the needs of the survey equipment. It is also very inconvenient to carry the buffer platform, resulting in reduced efficiency in the use of the buffer platform.

[0003] In response to the above problem, a Chinese patent announcement with announcement number CN216975661U discloses a highly stable buffer platform for geotechnical engineering survey, the technical highlights of which are: it includes a shock absorbing device, the shock absorbing device includes a pad and a spring, the bottom end of the pad is fixed with a spring, and a damper is fixed in the middle of the front side of the shock absorbing device, and the damper includes a damping rod and a gasket.

For this reason, we propose a buffer platform for geotechnical engineering survey to solve the above problems. Utility Model Content
