Supporting system for dismantling supporting beam in construction engineering

The invention provides a supporting system for dismantling a supporting beam in construction engineering. The supporting system comprises a plurality of supporting units and a hydraulic unit connected with the supporting units, and the hydraulic unit is used for providing hydraulic fluid and pressure for a plurality of supporting assemblies in the supporting units. The multiple supporting units and the hydraulic unit are both in communication connection with a control unit, and the control unit monitors working pressure parameters of all the units and conducts working pressure control. The supporting unit is provided with a second steel ball used for supporting the supporting beam to be dismantled, and the second steel ball is supported by a plurality of first steel balls at the bottom and on the spherical surface of the side face so that the second steel ball can roll freely. The tops of the second steel balls of the multiple supporting units form a supporting face to support the supporting beam to be disman
