Compared with the prior art, the open caisson with adjustable frictional resistance has the advantages that the controller 3 can timely acquire various data of the open caisson main body 1 during sinking, and then the controller 3 respectively controls the connecting piece 21, the supporting piece 22 and the stratum cutting piece 23 to operate so as to adjust the stress state of the corresponding position of the open caisson main body 1. Through the synergistic effect of the frictional resistance adjusting assemblies 2, the sinking process of the open caisson main body 1 is controllable, and the problems of attitude change or trajectory deflection caused by environment uncertainty are solved. And through the cutting crushing effect of stratum cutting piece 23 to the stratum wall, can effectively solve because the problem that the barrier of stratum wall leads to the caisson main part 1 can't sink. According to the invention, through regulating and controlling the connection state between the open caisson main body 1 and the stratum wall surface in real time in the sinking process of the open caisson main body 1, the technical problems of deviation of sinking quantities of different parts, deviation of the open caisson posture, even incapability of sinking or sudden sinking in the open caisson construction period in the prior art are solved.

The two ends of the first spring 223 are respectively connected with the first cylinder 221 and the second cylinder 222, and the arrangement of the first spring 223 limits the distance that the second sleeve 222 and the first sleeve 221 can move relatively. The first magnetic member 224 and the second magnetic member 225 are arranged so that the magnitude of the acting force between the supporting member 22 and the formation wall surface can be rapidly adjusted. The first magnetic member 224 and the second magnetic member 225 are magnetically connected, so that the structure is simple, and compared with the hydraulic device which can only be applied to an environment where a specific acting force in any direction is applied, the support member 22 is more applicable to an operating environment where the caisson body 1 is subjected to a plurality of acting forces in different directions during the sinking process, that is, the support member 22 can be applied to an operating environment where both longitudinal acting force and transverse acting force are applied.

In this embodiment, the first magnetic member 224 and/or the second magnetic member 225 are adjustable magnetic members, and the magnitude of the magnetic force generated by the adjustable magnetic members can be adjusted.
