The utility model relates to a steel casing vibrating at the front end. The steel casing comprises a steel cylinder body of which the cross section is in a circular shape, wherein a steel plate of which the length is equal to the inner diameter of the steel cylinder body is welded in the steel cylinder body along the diameter of the steel cylinder body, and the plane of the steel plate is parallel to the circular axial lead of the steel cylinder body; and the steel plate is close to the front end of the steel cylinder body. According to the steel casing, the steel plate is welded in the steel casing, and vibrating points can be positioned on the steel plate, so that a vibrating hammer can vibrate and sink the steel casing which is embedded into a pile hole; and the vibrating points are positioned at the front end of the steel casing, so that the loss of excitation force can be reduced, the drilling footage of vibration every time is increased, the vibration time is reduced, the requirement of the vibration hammer on the thickness of the steel casing is reduced, the thickness of the machining steel plate of the steel casing is reduced, and the cost is reduced.
