The invention provides a movable device filled with non-Newtonian fluid to resist impact force and a construction method. The device comprises a crawler belt used for supporting the whole device, wherein an arc-shaped steel plate is supported at the top of the crawler belt, the crawler belt is connected with a crawler belt engine used for driving the crawler belt to act, a plurality of non-Newtonian fluid injection openings are formed in the inner side wall of the arc-shaped steel plate, arch-shaped steel bars are uniformly distributed and fixed on the arc-shaped inner side wall of the arc-shaped steel plate, an inflatable air bag is arranged at the top of the arc-shaped steel plate, and the inflatable air bag is connected with an air bag inflation and deflation system. According to the device, the steel bars can be filled with the non-Newtonian fluid through a mold, so that the common steel bars can resist impact force caused by stronger impact ground pressure and tunnel support instability caused by overlar
