Seawater sea-sand concrete structure with corrugated composite pipe

Abstract

The invention discloses a seawater sea-sand concrete structure with a corrugated composite pipe. The seawater sea-sand concrete structure is composed of the corrugated composite pipe (1), seawater sea-sand concrete (2) and composite ribs (3). The corrugated composite pipe (1) is formed by means of the method that an inner fiber layer (11) and an outer fiber layer (13) are adhered to the inner wall and the outer wall of a corrugated steel pipe (12) correspondingly. The corrugated composite pipe (1) is in a corrugated curve line or fold line shape in the axial direction of a component. The composite ribs (3) are arranged in the corrugated composite pipe (1) in a matched mode, the seawater sea-sand concrete (2) fully fills the inside of the cross section of the corrugated composite pipe (1), and the composite ribs (3) are arranged in the seawater sea-sand concrete (2) and wrapped with the seawater sea-sand concrete (2). According to the seawater sea-sand concrete structure with the corrugated composite pipe, the defects existing in a publicly-known steel pipe concrete structure are overcome, and the seawater sea-sand concrete structure has the advantages that the bearing capacity is high, the corrosion resistance is good, materials are easy to obtain, and sustainable development is facilitated; and meanwhile, the structure has a low manufacturing cost, maneuverability is high, energy consumption is low, environment pollution is small, and the seawater sea-sand concrete structure with the corrugated composite pipe can be suitable for ocean engineering structure construction.

Description

technical field [0001] The invention belongs to the technical field of civil engineering structures, and in particular relates to a concrete composite structure, in particular to a corrugated composite pipe seawater sea sand concrete structure. Background technique [0002] Marine engineering construction is faced with extremely harsh natural corrosion environment. According to the environment, it can be divided into offshore, coastal, island and offshore, etc., all of which are subjected to environmental effects such as chloride ion erosion, alternating dry and wet, humid heat, freeze-thaw, etc. . In the process of marine engineering construction, reinforced concrete structures have been widely used, but the raw materials used must be fresh water and ordinary river sand, because chlorides and sulfates in sea sand will accelerate the corrosion of steel bars in concrete, seriously affecting Concrete durability. The requirement of raw materials for fresh water and ordinary r...
