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

[0032] Such as Figure 9 and Figure 10 , a construction method of fiberglass-steel root-shaped power pole tower piles, comprising the steps of:

[0033] ①. In the foundation pit 106 of the power pole tower cap, a plurality of curved holes 103 are drilled obliquely or downward by the pipe-pipe guide drill;

[0034] ②. Insert the cordless knot end of the FRP column 101 into the curved hole 103;

[0035] ③. Fill cement between the FRP column 101 and the hole wall to form a cement layer 102;

[0036] ④. The end of the knot 104 of the fiberglass column 101 is exposed in the foundation pit 106 of the cap;

[0037] ⑤. After the cement is solidified, support piles 105 are formed, and a plurality of support piles 105 form a cluster of piles for power poles and towers.

[0038] Such as Figure 11 As shown, the support pile 105 includes a glass fiber reinforced plastic column 101 and a cement layer 102 outside it, and the cement layer 102 is 10-20 mm thick; the diameter of the glas...

Abstract

The invention relates to a construction method of a glass fiber-reinforced plastic tree-root-shaped electric tower pile cluster. The method comprises a construction method of a bearing platform for electric towers stretching out of a support pile cluster slantly downwards or downwards, wherein the axis of the support pile is a curve; each support pile comprises a glass fiber-reinforced plastic cylinder and a cement layer outside the corresponding glass fiber-reinforced plastic cylinder. Due to the tree-root cluster-shaped structure, the motion amount of each support pile can be relatively large, but the comprehensive motion amount is very small after the cluster is formed; moreover, the bearing platform is supported and tensioned in all directions, and is still extremely stable under the effect of fluctuating wind power, so that no crack appears.

Description

technical field [0001] The invention relates to an on-site pouring tower pile cluster, in particular to a construction method of a glass fiber reinforced plastic tree root electric pole tower pile cluster. 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 plura...
