Further, the base 1 comprises a top plate 11, a first bottom plate 12, a web 13 located between the top plate 11 and the first bottom plate 12, and first stiffening plates 14 located at two sides of the web 13 and connected with the top plate 11 and the first bottom plate 12; in order to increase the contact area with the ground, the area of the first bottom plate 12 is larger than that of the top plate 11, so that the bolted steel tower 3 is prevented from being too heavy and crushing the ground; the contact area of the base 1 and the ground and the structural strength of the base meet the bearing requirements of the bolted steel tower 3.

Further, the support base 2 includes a second bottom plate 21, a connecting plate 22 connected to the tower wall of the bolted steel tower 3 and vertically fixed to the end of the second bottom plate 21, and second stiffener plates 23 vertically fixed to both sides of the second bottom plate 21 and fixedly connected to the connecting plate 22.

Further, the supporting seat 2 positioned on the outer side of the tower wall of the bolted steel tower 3 is connected with the base 1 through bolts, and the bolt holes are long holes; the supporting seat 2 positioned on the inner side of the tower wall of the bolted steel tower 3 and the base 1 are fillet welded, and can also be fixed in other modes convenient to operate. If the thickness of the bolted steel tower changes, the position of the support seat 2 positioned outside the tower wall can be adjusted through the strip bolt holes, so that the device can be recycled.
