The two rubber press rollers 8 of the air compressing assembly are matched to compress the travelling blanket 5 before being wound on the winding and unwinding mechanisms 4, so that the pre-filled air can always support the static cone penetration test vehicle between the two winding and unwinding mechanisms 4.

Referring to fig. 1 and 2, the thickness of the air bag 6 is not less than 2mm, and when the air bag 6 is inflated and expanded, the wall thickness becomes thinner, but a certain wall thickness can still be maintained, so that the air bag 6 cannot explode under the action of the gravity of the static cone penetration test vehicle.

The front end of the car body 1 is rotationally connected and is screwed with a push shovel 9 used for being inserted into soft soil through bolts, the push shovel 9 is arranged in a comb-tooth shape, and the push shovel 9 is positioned on one side of the travelling blanket 5, which is opposite to the car body 1.

In the running process of the static sounding vehicle, the pushing shovel 9 can push sundries such as broken stones and branches in soft soil, so that the possibility that the air bag 6 is punctured by sharp sundries is reduced.
