Abstract

The invention discloses a high-strength concrete-filled steel tube pile, which specifically relates to the technical field of concrete-filled steel tubes. A first anode ring is fixedly connected in the fixing ring, a second anode ring is fixedly connected in the second fixing ring, both the first anode ring and the second anode ring are attached to the steel pipe, and the inner cavity of the steel pipe is The sides are fixedly connected with a card seat, and the bottom of the inner cavity of the card seat is fixedly connected with a positioning column. By arranging the pipe body, the first fixing ring and the second fixing ring, the present invention exhibits good seismic performance, and the first anode ring and the second anode ring are used as protective electrodes to delay the corrosion rate of the whole steel pipe, which is different from the prior art. Compared with the overall extension of the corrosion resistance and seismic resistance of the concrete filled steel tube of the building foundation, the overall strength of the steel tube is improved, and the safety performance of the building is greatly improved.

Description

technical field [0001] The invention relates to the technical field of steel tube concrete, more specifically, the invention relates to a high-strength steel tube concrete pile. Background technique [0002] Ordinary concrete refers to the artificial stone made of cement as the main cementitious material, mixed with water, sand, stones, chemical admixtures and mineral admixtures when necessary, mixed in an appropriate proportion, and uniformly stirred, compacted and cured. . Concrete is mainly divided into two stages and states: the plastic state before setting and hardening, that is, fresh concrete or concrete mixture; the hard state after hardening, that is, hardened concrete or concrete. In order to increase the strength and rigidity of steel pipes, the application of concrete filled steel pipe piles in pile foundation engineering in my country is still less, but they all reflect many of its excellent characteristics. Its outer steel pipes restrain the inner concrete, so...
