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] A flat spherical power tower foundation, such as Figure 9 and Figure 10 As shown, it includes a platform 105, the platform 105 is an oblate spherical reinforced concrete structure, and the oblate spherical platform 105 is provided with a reinforcement cage 107, and the reinforcement cage 107 is also oblate.

[0026] Such as Figure 10 As shown, the oblate spherical cap 107 protrudes obliquely or downwards to support pile clusters, and the support pile clusters are composed of support piles 106 .

[0027] Such as Figure 11 and Figure 12 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 . The wall thickness of the rubber pipe body 102 is 10-20 mm, and the diameter of the reinforced concrete column body 101 is 50-100 mm.

[0028] The construction method of oblate spherical power tower foundation of th...

Abstract

A flat-ball type power tower foundation comprises a flat-ball shaped bearing platform. The interior of the flat-ball shaped bearing platform is of a reinforced concrete structure. The flat-ball shaped bearing platform extends obliquely downwards or downwards to form supporting pile clusters which are composed of supporting piles. The axis of each supporting pile is curved, and each supporting pile comprises a reinforced concrete cylinder and a rubber hose outside the reinforced concrete cylinder. The power tower foundation is flat-ball shaped, so that more supporting piles can be paved; the supporting piles paved into a clustered structure are like roots of a big tree, the bearing platform can be supported and tensioned in all directions, and the comprehensive activity of the bearing platform can be offset with one another; the supporting piles are firmly stationed in the ground, so that cracks can be avoided.

Description

technical field [0001] The invention relates to a plurality of piles driven into the foundation through a concrete structure, in particular to an oblate spherical power tower foundation. 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 anchor bolt...
