The invention discloses a four-track intelligent slipform paver and a stand column floating electrohydraulic control system thereof, and relates to the technical field of road surface machinery. The control system is used for controlling hydraulic oil cylinders in a left front stand column, a left rear stand column, a right front stand column and a right rear stand column of the four-track intelligent slipform paver, and comprises a controller, a hydraulic oil source, an oil tank, a first electric control reversing valve, a second electric control reversing valve, a third electric control reversing valve, a fourth electric control reversing valve, a floating valve group, a fifth electromagnetic reversing valve, a two-position six-way reversing valve, a first double balance valve, a seconddouble balance valve and a third double balance valve. According to the paver and the control system, the stand columns of the built-in hydraulic oil cylinders are all in the floating state, the problem that in the background technology, the paving flatness becomes poor due to rack deformation, and the paver travels in an unstable mode due to suspension of a stand column track assembly, so that the structure direction precision is reduced is effectively solved, and the structure precision is guaranteed when the four-track intelligent slipform paver performs construction in a side-arranging mold mode.
