The invention provides a push type diker and a diking method thereof. According to the push type diker and the diking method thereof, the diker is positioned to the position where diking needs to be conducted, and the diker is made to sink into silt gradually under the action of a jetting hole; then stones are thrown into a forming cabin of the diker, a piston rod of a pushing oil cylinder stretches out backwards to push the stones after the height of the stones is larger than that of the pushing oil cylinder on the diker, and forward counter-acting force can be provided for the whole diker by the stones due to the fact that firm silt behind the stones cannot be squeezed open by the stones; the jetting hole works all the time to activate and push open the silt in front and below, so that the diker advances to squeeze open the silt in front, and stones are thrown by the diker continuously when the diker advances, so that the lower portion of a sea dike is dump-filled; then the upper portion of the sea dike is dump-filled through a conventional method, so that construction of a dike body of the whole sea dike is completed. By the adoption of the push type diker and the diking method thereof, the constructed dike body can be well matched with a construction drawing, and stones can be saved; meanwhile, diking can be conducted under complicated geological conditions, and thus the push type diker and the diking method thereof are highly practical.
