Problems solved by technology

Since the designed bearing platform can resist both pressure and tension, the force causing the crack of the bearing platform is mainly vibration force, and this patent only solves the problem of pressure and tension, but does not solve the problem of vibration force

Embodiment Construction

[0025] Such as Figure 9 As shown, the tree-rooted power tower pile cluster includes four caps 105 at the foot of the power tower; the caps 105 are provided with supporting piles 106, based on the square connecting the centers of the four power towers, Out of the square, support piles 106 extend downward and outward.

[0026] Such as Figure 10 As shown, the axes of the supporting piles 106 are curved lines, and each supporting pile 106 includes a reinforced concrete column body 101 and a rubber tube body 102 outside the reinforced concrete column body 101 .

[0027] The wall thickness of the rubber pipe body 102 is 10-20mm; the diameter of the reinforced concrete cylinder 101 is 50-100mm.

[0028] Construction method of tree-rooted power tower pile cluster:

[0029] ① With the square foundation pit formed by the center of the four caps 105 as the boundary, drill a predetermined curved hole with a pipe-pipe guide drill obliquely downwards into the soil 103 outside the squar...

Abstract

The invention discloses a tree-root-shaped electric tower pile cluster which comprises four bearing platforms on electric tower feet, wherein supporting pile columns of the bearing platforms extend outwards and downwards outside a square formed by connecting the centers of the four bearing platforms of an electric tower. The axis of each of the supporting pile columns is a curve, and each supporting pile column comprises a reinforced concrete column body and a rubber tube body outside the reinforced concrete column body. Due to the tree-root-shaped cluster structure, the comprehensive quantity of motion after the cluster is formed is very small although the quantity of motion of each supporting pile column is relatively large, the bearing platforms are supported and tensioned in all directions, so that the bearing platforms are still very stable under the action of turbulent wind, and no crack occurs.

Description

technical field [0001] The invention relates to a plurality of piles to be driven into the foundation through a concrete structure, in particular to a pile cluster of tree-rooted power towers. Background technique [0002] As the foundation structure supporting the main pile of the iron tower, in the case of a relatively deep support layer, such as figure 1 As shown, after driving a plurality of relatively small piles 50 in the foundation, reinforced concrete is used to make footings 51 connecting the tops of these piles 50, and the footings 51 are connected to the main piles 52 of the iron tower. The method is generally used (refer to the following patent document 1 etc.). [0003] In addition, the fixing structure of the footing 51 and the main pile 52 can be roughly classified into a bolt fixing method, an anchor member fixing method, a support plate fixing method, and the like. The bolt fixing method is as figure 1 Shown, is the mode that utilizes a plurality of ancho...
