Composite pipe pile with inner ribs

Abstract

The invention discloses a composite pipe pile with inner ribs. The composite pipe pile comprises a composite winding pipe and concrete which is used for filling the composite winding pipe. The composite winding pipe comprises a composite internal mold round pipe, longitudinal ribs and fibers, wherein the longitudinal ribs are arranged on the inner wall of the composite internal mold round pipe, and the fibers are wound on the outer wall of the composite internal mold round pipe to form the composite winding pipe. According to the composite pipe pile with inner ribs, the pipe pile and pier stud concrete can be prevented from being corroded by harmful substances, the compressive strength of concrete can be improved, and the interfacial adhesive strength of the composite pipe and concrete can be enhanced, so that the pipe pile and pier studs are durable in structure, and the ductility of concrete pier studs can be improved simultaneously.

Description

technical field [0001] The invention relates to a pipe pile, in particular to a new type of pipe pile that can improve the bonding performance between the composite material outer pipe and the core concrete, and can be used for prefabricated pipe pile foundations and bridge pier columns in newly built structures in corrosive environments such as oceans, and can also be used for Reinforcement of existing reinforced concrete and prestressed concrete piers. Background technique [0002] Reinforced concrete, prestressed reinforced concrete pipe piles or cast-in-situ pile foundations are one of the pile foundation forms commonly used in civil engineering. At the same time, existing bridge piers are mostly made of reinforced concrete and prestressed reinforced concrete structures. In the marine environment, although the corrosion of concrete structures is slower than that of steel structures, it is easy to be ignored, but once it occurs, it is difficult to repair and deal with.

Problems solved by technology

[0005] The purpose of the present invention is to solve the problem that the interface between existing composite material confined concrete pipe piles and pier columns is easy to peel off, and to provide a composite material pipe with longitudinal and transverse ribs that can be realized through continuous production technology. The pipe can not only protect the pipe pile and pier concrete from the erosion of harmful substances, improve the compressive strength of the concrete, but also enhance the interface bond strength between the composite pipe and concrete, making the pipe pile and pier structure more durable , while improving and enhancing the ductility of concrete piers
