Description

Technical Field

[0001] This utility model relates to the technical field of civil engineering, and in particular to an impact-resistant prefabricated prestressed anchor foundation. Background Technology

[0002] Traditional anchor foundation construction often employs on-site casting or precast component assembly, which suffers from problems such as long construction periods, high costs, and limited impact resistance. Especially in areas prone to natural disasters such as water erosion and earthquakes, traditional anchor foundations struggle to meet long-term stability and safety requirements. Therefore, it is essential to develop a prestressed prefabricated anchor foundation with strong impact resistance. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a prefabricated prestressed anchor foundation with short construction period, low cost and impact resistance.

[0004] This utility model discloses an impact-resistant prefabricated prestressed anchor foundation, comprising multiple sets of prefabricated main bodies stacked together, with the area of ​​the upper prefabricated main body being smaller than that of the lower prefabricated main body. Each set of prefabricated main bodies has a set of anchor holes at its center and multiple sets of wire-passing holes circumferentially arranged on its upper axis. In use, the multiple sets of prefabricated main bodies are stacked, with larger prefabricated main bodies below smaller ones. Prestressed steel strands connect the multiple sets of prefabricated main bodies from top to bottom, forming a stable overall foundation. The anchor holes on each set of prefabricated main bodies overlap for installing anchors, and the multiple sets of wire-passing holes on the prefabricated main bodies overlap for threading prestressed steel strands. This shortens the construction time of the anchor foundation, reduces costs, and improves impact resistance.

[0005] Preferably, the cross-sectional area of ​​the prefabricated body is a regular circle; the prefabricated body adopts a circular design, which facilitates the stacking of multiple prefabricated bodies and the formation of a stable basic structure.

[0006] Preferably, the precast component body is made of high-strength concrete; the precast component body made of high-strength concrete has the characteristics of high compressive strength, strong impermeability and low material consumption, which improves construction quality and reduces construction costs.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, multiple sets of precast main bodies are stacked, with the larger precast main body below the smaller precast main body. Prestressed steel strands connect the multiple sets of precast main bodies from top to bottom to form an overall stable foundation. The anchor holes on each set of precast main bodies overlap for installing anchors. The multiple sets of wire holes on the precast main bodies overlap for threading prestressed steel strands, which shortens the construction time of the anchor foundation, reduces costs, and improves impact resistance.

[0012] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0013] Example

[0014] like Figures 1 to 3 As shown, this utility model provides an impact-resistant prefabricated prestressed anchor foundation, which includes a prefabricated body 1. The prefabricated body 1 is in multiple groups, and the multiple groups of prefabricated body 1 are stacked. The area of ​​the upper prefabricated body 1 is smaller than that of the lower prefabricated body 1. Each group of prefabricated body 1 has a set of anchor holes 3 at its center, and each group of prefabricated body 1 has multiple sets of wire holes 2 arranged circumferentially on its upper axis.

[0015] The cross-sectional area of ​​the prefabricated body 1 is a regular circle;

[0016] The precast component body 1 is made of high-strength concrete.

[0017] In this embodiment, multiple sets of precast main bodies 1 are stacked together, with the larger precast main body 1 below the smaller precast main body 1. Prestressed steel strands connect the multiple sets of precast main bodies 1 from top to bottom to form a stable overall foundation. The anchor holes 3 on each set of precast main bodies 1 overlap for installing anchors. The multiple sets of wire holes 2 on the precast main bodies 1 overlap for threading prestressed steel strands, which shortens the construction time of the anchor foundation, reduces costs, and improves impact resistance.

[0018] The prefabricated main body 1 of the impact-resistant prestressed anchor foundation of this utility model is purchased from the market. Technical personnel in this industry only need to install and operate it according to the accompanying instruction manual, without requiring any creative work from those skilled in the art.
