The invention discloses a method for controlling implantation of a steel casing based on a drill hammer. The method comprises the following steps of 1, lowering of the steel casing: lowering the steel casing onto a river bed; 2, positioning and installation of a drilling machine: according to the construction position of the constructed water pile, positioning and installing the drilling machine, and enabling the drill hammer of the drilling machine to be just above the construction position of the constructed water pile; 3, lifting of the steel casing: enabling lifting equipment to upwards lift the steel casing, and suspending the steel casing; 4, lowering of the drill hammer: lowering the drill hammer of the drilling machine, and horizontally clamping the drill hammer into the steel casing, wherein the steel casing is in a vertical state under the self gravity state, and the position of the steel casing is adjusted by the drill hammer; 5, implantation of the steel casing: lowering the steel casing onto the river bed. The method has the advantages that the steps are simple, the design is reasonable, the control is simple and convenient, and the use effect is good; by accurately positioning the drilling machine, the implantation control process of the steel casing is simply and conveniently completed by the drill hammer, and the implantation accuracy of the steel casing is guaranteed.
