The present invention relates to a dredging apparatus and, more specifically, relates to a dredging apparatus including an outrigger moving a main body of the dredging apparatus; and fixedly supporting the main body on a working point of a dredging water zone. The outrigger comprises: a rotating bracket coupled to the main body of the apparatus through a hinge in such a manner where the rotating bracket can be rotated by an operational cylinder; a supporter guide fixated to the rotating bracket; a plurality of supporters inserted into the supporter guide and drawn in multi-stages; and a hydraulic cylinder inserted into the supporter and an upper end fixated to the supporter guide. A hydraulic rod is connected to a lower end of the hydraulic cylinder, a first nipple is installed in the upper end of the hydraulic cylinder, and a second nipple connected with a lower supply pipe is further included in the upper end in such a manner where the second nipple is stepped with the first nipple. The lower supply pipe is connected to the lower end of the hydraulic cylinder such that the hydraulic rod is elevated or descended depending on the nipple provided with fluid pressure. According to the present invention, the outrigger can rapidly be descended to a position where the outrigger needs to be settled after being moved to the dredging water zone such that a regular position fixing work can smoothly and effectively be performed.
