Concrete pile locally provided with stainless steel bars and construction method thereof

Abstract

The invention discloses a concrete pile locally provided with stainless steel bars and a construction method thereof. The concrete pile comprises a concrete body, a plurality of main bar structures, a plurality of first stirrups and a plurality of second stirrups. The main bar structures are arranged in the concrete body, each main bar structure comprises two first main bars and one second main bar, the two first main bars are connected with the two ends of the second main bar respectively, the first main bars are made of carbon steel, and the second main bar is made of stainless steel. The multiple first stirrups are arranged in the concrete body and connected with the first main bars, the multiple first stirrups are distributed in the length direction of the first main bars, and the first stirrups are made of the carbon steel. The multiple second stirrups are arranged in the concrete body and connected with the second main bar, and the second stirrups are made of the stainless steel. According to the concrete pile, the chlorine salt corrosion resistance of the concrete pile can be improved, so that the service life of the concrete pile is remarkably prolonged, and the whole life cycle cost of the concrete pile is reduced.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a concrete pile partially equipped with stainless steel bars and a construction method thereof. Background technique [0002] Bridges, port terminals, offshore platforms and other related structures in offshore and marine environments need to use concrete structures for load bearing or other supporting functions. There are a lot of chlorine salts in the offshore and marine environment. Under the long-term action of aggressive chlorine salts, the steel bars in the concrete structure are prone to corrosion, which leads to the degradation of the mechanical properties and durability of the concrete structure, and shortens the service life of the concrete structure. will cause significant economic losses. [0003] Therefore, there is an urgent need for a concrete pile, which can not only have a lower construction cost in a marine environment, but also solve the problem of d...
