Description

Technical Field

[0001] This utility model relates to the field of anti-tension pile construction technology, and in particular to a concrete anti-tension pile installation structure containing fiber-reinforced composite reinforcement. Background Technology

[0002] In areas with high water levels, tension piles are a common construction method for pile foundation construction. However, existing tension piles use ordinary steel bars as the main reinforcement. Ordinary steel bars are composed of iron and carbon materials, which are prone to corrosion and have poor durability in corrosive environments such as seawater. This can lead to structural safety risks and increased maintenance costs. Therefore, it is necessary to design a corrosion-resistant and high-strength reinforcement material to ensure the durability of tension piles and save on material costs. Utility Model Content

[0003] This utility model provides a concrete tensile pile installation structure containing fiber-reinforced composite reinforcement to solve the technical problems of easy corrosion and low strength of the main reinforcement in tensile piles.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A concrete pull-out pile installation structure containing fiber-reinforced composite reinforcement is characterized by comprising a pile hole set below ground, a pile reinforcement assembly set in the pile hole, pile body concrete poured inside and around the pile reinforcement assembly, a chisel section set on top of the pile body concrete and cast integrally, and a backfill section set on top of the chisel section. The pile reinforcement assembly includes main pile reinforcement, pile helical reinforcement disposed in the height direction of the main pile reinforcement, and pile reinforcing reinforcement disposed at intervals in the height direction of the main pile reinforcement. The main reinforcement of the pile includes a composite reinforcement body and an outer rib strip on the outside of the composite reinforcement body. The composite reinforcement body includes a carbon fiber layer at the center and a basalt fiber layer around the carbon fiber layer.

[0005] Furthermore, the main reinforcement of the pile includes the main through reinforcement and the main supplementary reinforcement, which together form a ring and are arranged alternately.

[0006] Furthermore, the main reinforcement bar of the pile is installed from top to bottom along the entire length of the pile hole, and the top of the main reinforcement bar is reserved with the length of reinforcement bar to be connected to the superstructure.

[0007] Furthermore, the height of the additional reinforcement bars for the main pile is set within the design range for strengthening the pull-out pile.

[0008] Furthermore, the pile spiral reinforcement is installed along the entire length of the pile main reinforcement within its height range; the pile reinforcing reinforcement is arranged in a ring shape and is installed along the entire length of the pile main reinforcement within its height range.

[0009] Furthermore, the pile body concrete and the chiseling section are cast as a whole, with the top of the chiseling section being the casting elevation and the bottom being the pile top elevation.

[0010] Furthermore, the carbon fiber layer and the basalt fiber layer are filled with adhesive and bonded together by compression.

[0011] Furthermore, the outer rib strip is a groove formed by crimping the winding thread, and the groove is spirally arranged along the entire length of the composite rib in the height direction.

[0012] The beneficial effects of this utility model are reflected in: This invention utilizes a composite reinforcement structure. The basalt fiber layer is corrosion-resistant, and its combined with the carbon fiber layer provides higher strength, both ensuring the durability of the main reinforcement of the pull-out pile and saving materials, thus reducing costs. Furthermore, the external ribs further enhance the strength of the composite reinforcement, ensuring structural stress resistance. During pile reinforcement construction, the use of main through reinforcement and additional main reinforcement further guarantees local strength and saves materials. Other features and advantages of this invention will be set forth in the following description and will be apparent in part from the description, or may be learned by practicing the invention. The main objectives and other advantages of this invention can be realized and obtained by means of the methods specifically pointed out in the description. Attached Figure Description
