Embodiment 1

[0037] Figure 1 to Figure 4 Embodiment 1 of the axial anchor pile in this invention is embodied. The axial anchor pile in this embodiment is composed of the following parts: the axial anchor pile 10 composed of the axial anchor pile main body 11 and a plurality of shafts 12, 13, 14 connected to the outer peripheral surface of the above-mentioned axial anchor pile main body 11 the first axial anchor pile 20 located at the upper part of the above-mentioned axial anchor pile 10, the lower end of which is connected to the upper end of the axial anchor pile main body 11; The second shaft anchor pile 30 to be connected.

[0038] Actually, the number of axial anchors is determined by the depth of the entire anchor, but in the illustrated example, only the first axial anchor 20 and the second axial anchor 30 are shown for convenience. The shaft anchor main body 11 , the first shaft anchor 20 and the second shaft anchor 30 are all tubular. Among the above-mentioned shafts 12, 13, 1...

Embodiment 2

[0078] Figure 5Embodiment 2 of the axial anchor pile in this invention is embodied. In this embodiment, the outer peripheral portion of the shafts 12, 13, 14 of the shaft anchor pile 10 has a plurality of shearing parts 12a, 13a, 14a, and each shaft 12, 13, 14 can make the shafts 12, 13, 14 13, 14 are subjected to soil resistance to a minimum. In addition, cutting knives 12b, 13b, 14b are installed on each of the shearing parts 12a, 13a, 14a, which can improve the ground cutting ability, and promote the axial anchor pile 10, the first axial anchor pile 20 and the second axial anchor pile 30 to be more stable. penetrated smoothly. At the same time, a small hydraulic rotating device can be used to save equipment costs.

[0079] After comparing the shafts using the prior art with the shafts 12, 13, 14 of the first embodiment above, it can be seen that the shafts using the prior art and the shafts 12, 13, 14 in the first embodiment are all in the form of a single spiral plate ...

Embodiment 3

[0085] Figure 6 Embodiment 3 of the axial anchor pile in this invention. The above-mentioned axial anchor pile in this embodiment is composed of the following parts: it is welded on the lower part of the bolt part 15 at the upper end of the above-mentioned axial anchor pile 10, and can simultaneously determine the position of the lower end of the first joint 40 and the welding position of the lower end of the first joint 40 Positioning and welding ring 16; welded on the lower part of the bolt portion 21 at the upper end of the first shaft anchor pile 20, the positioning and welding ring 23 that can simultaneously determine the position of the lower end of the second connector 50 and the welding position of the lower end of the second connector 50; be welded At the lower part of the bolt part 31 at the upper end of the second shaft anchor pile 30, the positioning and welding ring 33 that can determine the position of the lower end of the third joint 60 and the welding position...

Abstract

The invention relates to a shaft anchor pile. A bolt and a nut for the shaft anchor pile respectively fixes a main body and a connected first connecting head, a first shaft anchor pile and a connected second connecting head, and a second shaft anchor pile and a connected third connecting head. The first connecting head is welded on a shaft anchor pile body; the second connecting head is welded on the first shaft anchor pile; and the third connecting head is welded on the second shaft anchor pile, so that the structure is more rigid; and when the torque is higher, the connecting heads cannot be separated from the shaft anchor piles. The shaft anchor pile has multiple shafts; shearing parts are mounted at the outer peripheral parts of the shafts; and when the shafts are inserted in the ground, the resistance of soil can be reduced to the greatest extent. Cutters are mounted on the shearing parts for improving the ground cutting capacity. The lower end of the shaft anchor pile is connected with a through hole tooth crown; the through hole tooth crown has an outer peripheral cutting head and a lower end cutting head manufactured by materials with higher cutting force; and before shaft cutting of the ground, the through hole tooth crown is firstly used for drilling on the ground, so that the ground drilling and the cutting are more effective.

Description

technical field [0001] The invention relates to a shaft anchor pile, more specifically, a joint between the shaft anchor pile and the shaft pile and the connection between the shaft piles, which can be smoothly constructed even if rocks are encountered during the construction process. The parts are very strong, and the construction safety can be ensured even if the torque is large during construction. At the same time, small hydraulic rotating devices can also be used for construction, which is more economical. Background technique [0002] In general, when constructing the weight-supporting foundation of a building or civil structure, the anchor pile must be penetrated into the ground. The hammering method of beating the anchor pile or the press-in method of applying a pressing force to the anchor pile have been used since ancient times. Law. However, the hammering method and the press-fit method cause safety and environmental problems due to noise and vibration during co...
