A combination tower base device is used for a base of a telecommunication launching tower, which comprises a steel body and a steel anchor. The steel body is made by welding more than three steel plates together into a cone or cylinder or polygon shape. A wing board is arranged around the middle and the lower part of the body and a plurality of connection holes are arranged around the lower steel body. The steel anchor comprises the steel anchor pole on the upper part and the anchor slip on the lower part. The steel anchor pole is welded with the connection hole under the steel body and forms an umbrella shape. The head anchor slip turns into a single or multi-layer screwy slip structure around the steel anchor pole. With the utility model, the space of the tower base and the amount of concrete can be reduced, and the construction period and the cost are reduced accordingly. The quantities for combination of the anchor groups to be arranged can be calculated according to the geological conditions. The combination of groups is a biomorphic base, which stretches out deeply into the stratum and keeps the tower steady as if the plant roots maintain the stability of the trunks. The steel pipe not only is a tower base moulding board, but also can substitute the reinforced bars in the concrete.
