Problems solved by technology

When this method is used in underwater construction, the requirements for divers are high, and the operation is relatively complicated. When the fiber cloth is wound to strengthen the pier column structure, part of the water will inevitably be wrapped in it, which will affect the bonding effect of the resin glue and the resin glue is easy to Ageing

Abstract

The invention discloses an FRP (Fiber Reinforced Plastic) pipe confined cement based composite material reinforced pier column structure applied to reinforcement of pier columns with all structures. The FRP pipe confined cement based composite material reinforced pier column structure comprises a pier column, a fiber reinforced composite material base arranged at the bottom of the pier column, a fiber reinforced composite material pipe arranged around the pier column, a limiter fixing the position of the fiber reinforced composite material pipe, and an engineering cement based composite material filling a gap between the fiber reinforced composite material pipe and the pier column. The advantages of the fiber reinforced composite material base, the fiber reinforced composite material pipe, the engineering cement based composite material and fiber grid meshes are integrated and can be fully played, the excellent performance of a single material can be greatly improved under the action of mutual adhesion of the fiber reinforced composite material base, the fiber reinforced composite material pipe, the engineering cement based composite material and the fiber grid meshes, and the bearing capacity, the erosion resistibility, the anti-seismic property, the ductility, the fatigue resistance and the durability of the pier column structure are effectively improved.

Description

technical field [0001] The invention belongs to the fields of civil engineering, construction engineering, highway engineering and municipal engineering, and relates to an FRP pipe-constrained cement-based composite material-reinforced pier column structure. Background technique [0002] Reinforced concrete structures have been widely used in engineering fields such as civil engineering and civil construction, and have become the most widely used structures in our lives. As the main force-bearing member of the structure, the pier column's safety performance affects the overall performance of the entire structure. Due to defects in construction level and design standards, various structural diseases are gradually exposed, especially in harsh environments, such as freeze-thaw, acid, alkali and salt environments, as well as under the impact of rivers and sea water, vehicles, etc. The performance is particularly obvious. The common structural defects of pier columns are reflec...
