The invention discloses an
assembly-type composite tube sea-water sea-sand concrete bridge
pier. The structure of the bridge
pier is composed of multiple composite tube sea-water sea-sand concrete column segments (100) which can be stacked, and the composite tube sea-water sea-sand concrete column segments (100) are connected into an entirety through back-tension prestressing force. The
assembly-type composite tube sea-water sea-sand concrete bridge
pier is characterized in that the composite tube sea-water sea-sand concrete bridge pier column segments are formed by composite tubes (1), sea-water sea-sand concrete (2), corrugated pipes (3), prestressing ribs (4) and anti-shear ribs (7), one or more pairs of protruding ribs (6) and grooves (5) are arranged between seams of every two composite tube sea-water sea-sand concrete bridge pier column segments, and the protruding ribs (6) and the grooves (5) are glued through a cementing material; each composite tube sea-water sea-sand concretebridge pier column segment (100) is provided with the corresponding corrugated
pipe (3) in the height direction, and one or more prestressing ribs (4) penetrate through the corrugated pipes (3) of each column segment. The
assembly-type composite tube sea-water sea-sand concrete bridge pier has the advantages that the bridge pier is good in durability, high in
bearing capacity and good in
corrosion resistance, the materials are easy to take, and the bridge pier is beneficial to
sustainable development; meanwhile, the structure of the assembly-type composite tube sea-water sea-sand concrete bridge pier has the advantages that the structure can be prefabricated and transported in a large scale, is convenient to
mount, short in construction period, low in
energy consumption and little in environmental
pollution, and can be suitable for
marine engineering structural construction.
