A steel pipe concrete pile

Abstract

The invention relates to the technical field of building materials, in particular to a steel pipe concrete pile, including steel pipes, concrete, piling structures, anti-collision structures, maintenance structures and fixed structures; When hitting the concrete-filled steel pipe pile by accident, it can fully buffer the ship, so as to avoid damage to the ship when the ship hits the concrete-filled steel pipe pile, ensure the safety of the people on the ship, and drive the maintenance while the anti-collision structure is working. The structure works, that is, the anti-collision structure can inject river water into the concrete inside the steel pipe through the maintenance structure, so that the concrete layer inside the steel pipe can be water-filled and cured, thereby prolonging the service life of the concrete inside the steel pipe, that is, improving the concrete of the entire steel pipe. The service life of the pile, and the maintenance structure can also react on the anti-collision structure, so that the anti-collision effect of the anti-collision structure is better.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a steel pipe concrete pile. Background technique [0002] Concrete filled steel pipe is to pour concrete into the steel pipe and compact it to increase the strength and rigidity of the steel pipe. Generally, we call the concrete-filled steel tube concrete with a concrete strength level below C50 called ordinary steel-filled steel tube concrete; the concrete-filled steel tube with a concrete strength level above C50 called high-strength steel tube concrete; . Concrete-filled steel pipe refers to the structural member formed by filling concrete in the steel pipe, and the steel pipe and its core concrete can bear the external load together. . [0003] At present, concrete-filled steel pipe piles are also used in the erection of some bridges. The concrete-filled steel pipe piles installed in narrow and ship-passing rivers often cause accidental collisions of ships. Beca...

Problems solved by technology

[0003] At present, concrete-filled steel pipe piles are also used in the erection of some bridges. The concrete-filled steel pipe piles installed in narrow and ship-passing rivers often cause accidental collisions of ships. Because the concrete-filled steel pipe piles are relatively hard, ships may be damaged. Happening
