Experiment device for spudcan penetration and pullout of jack-up rig

An experiment device for spudcan penetration and pullout of a jack-up rig, comprising an experiment bench and a spudcan leg, wherein the experiment device further comprises:

• a ballasting tank;
• supporting wheels provided on the experiment bench;
• a suspension rope which is wound around the supporting wheels, and has two ends being connected respectively to the spudcan leg and the ballasting tank, wherein the ballasting tank has a first state of being seated on the spudcan leg and a second state of being separated from the spudcan leg and suspended under the suspension rope, when the ballasting tank is in the first state, a gravity of the ballasting tank acts as a penetration pressure exerting on the spudcan leg, and when the ballasting tank is in the second state, the gravity of the ballasting tank acts as a pullout force exerting on the spudcan leg through the suspension rope;
• and
• a linear driving device coupled to the ballasting tank, wherein the linear driving device makes the ballasting tank switch between the first state and the second state by driving the ballasting tank to move linearly in a horizontal direction perpendicular to a height direction of the spudcan leg.
