Strong tamping machine

The utility model relates to a strong tamping machine, belonging to a construction machine for foundation treatment, and comprising a lifting part, a shifting part and a supporting part. The utility model is characterized in that the supporting part is a rigid vertical framework which is inclined inward in a definite angle and comprises three upright posts 5, an upper cover 12 and a bottom board 4. Simultaneously the length of the upright posts 5 can be adjusted. The utility model has the advantages of eliminating the instable element caused by the supporting resilient force and conveniently carrying the operation of shifting and walking and overcomes the defect that the arm rod of a crane is used as a three-point form support, and the power part uses a windlass instead of a crawler crane, thus greatly reducing cost and constructing expenses. The safety is ensured, the efficiency is enhanced, and one machine has a plurality of functions.
