The present invention relates to an automatic correction support for a slope of a bridge installation apparatus to automatically maintain the balance of the support, even though the ground is not flat and sloped in a process of moving the boom across a river and installing the support. The automatic correction support for a slop of a bridge installation apparatus comprises: a central reinforcement bar; a plurality of side reinforcement bars connecting to and installing on the outer surface of the central reinforcement bar; and footings which are connected to the lower side of the side reinforcement bars and come to directly contact with the ground. The present invention includes: a plurality of cylinder tubes coupled with the outer surface of the central reinforcement bars by fixing pins, respectively, and having chambers to fill the fluid inside the same; and cylinder members having piston rods and one ends of the piston rods inserted in the chamber of the cylinder tube and the other end of the piston rods inserted in the side reinforcement bars, respectively, to move up and down by a pressure transmitted from the footings for connecting and composing the side reinforcement bars to the central reinforcement bars to be able to adjust the length thereof. A plurality of the cylinder tubes are connected and composed by a first and second hose to circulate the fluid which is stored in chambers of the cylinder tubes through the first and second hose according to the up-down movement of the piston rod. The control valve, which is operated by the driving of control means and intermits the flow of the fluid which flows in the first and second hose, is installed in the first and second hose. |
