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
[0031] A method for preparing a fiberglass bionic power tower pile, comprising the steps of:
[0032] ①. Preparing thick glass silk rope 104;
[0033] ②. Immerse the thick glass rope 103 of the required length into the resin tank to infiltrate the resin to form the resin layer 104;
[0034] ③. In the resin tank, according to the texture of the glass fiber rope 103, tighten it from both ends, squeeze out the excess, and leave the resin tank;
[0035] ④. Tighten one end of the resin-soaked glass rope with a knot 105;
[0036] ⑤. curing the knotted glass rope to obtain the glass fiber reinforced plastic cylinder 101;
[0037] ⑥. The fiberglass cylinder 101 is covered with a cement layer 102 to form a tower pile.
[0038] See Figure 9 , the wall thickness of the cement layer 102 is 10-20mm; the diameter of the FRP cylinder 101 is 50-100mm. The FRP cylinder 101 is curved. The resin is an unsaturated polyester resin. The cement is expansive cement.
[0039] There are two me...

Abstract
The invention discloses a preparation method of bionic electric tower piles made of glass fiber reinforced plastics. The preparation method comprises the following steps: preparing coarse glass-fiber cords; immersing the coarse glass-fiber cords into a resin tank, and soaking the coarse glass-fiber cords in resins so as to form resin layers; tightening both ends of each of the coarse glass-fiber cords in the resin tank according the texture of the glass-fiber cords, squeezing out redundant resins, and taking the coarse glass-fiber cords out of the resin tank; knotting one ends of the coarse glass-fiber cords which are tightened and soaked in the reins; solidifying the knotted glass-fiber cords so as to obtain a column body made of glass fiber reinforced plastics; wrapping the column body made of glass fiber reinforced plastics with a cement layer on the outsides so as to obtain the tower piles. When the vibration of an electric tower base, which is caused by wind, is passed to each tower pile, rubber pipe bodies, like tree roots, can reduce vibration, so that the vibration caused by the turbulent wind velocity can be counteracted; a bearing station is stably stationed on the ground, so that the appearance of cracks is avoided. Through the adoption of the bionic electric tower pile made of glass fiber reinforced plastics, which is prepared by the preparation method disclosed by the invention, the base of the electric tower can be maintained, and the service life of the electric tower can be prolonged.
Description
technical field [0001] The invention relates to a plurality of piles driven into a foundation through a concrete structure, in particular to a preparation method of a fiberglass bionic electric tower pile. 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...
