Abstract

The invention discloses a composite material grid structure and reinforcement concrete combined pile and a construction method thereof. The pile comprises a concrete pile body and N layers of composite material reinforced bodies arranged in the concrete pile body, wherein N is larger than or equal to 1. Each layer of composite material reinforced body comprises a longitudinal main rib, a transverse main rib and an inclined web rib. The longitudinal main ribs are symmetrically arranged according to the shape of the section of the pile. The transverse main ribs are longitudinally arranged at intervals. The longitudinal main ribs and the transverse main ribs are vertically and fixedly connected, and the formed intersection points are connected through the inclined web ribs. The N layers of composite material reinforced bodies are concentrically arranged from inside to outside. The transverse main ribs on the every two adjacent composite material reinforced bodies are located on the same plane, the longitudinal main ribs on the every two adjacent composite material reinforced bodies are staggered, and the every two layers of composite material reinforced bodies are connected through the longitudinal web ribs and the transverse web ribs. Either prefabricating piling or site pouring can be selected for the construction method. The interlock capacity of the composite material reinforced bodies and the concrete is improved, the defect of stripping among materials in the use process of the composite material pile is overcome, rebars are replaced by composite materials, and the overall combined pile is resistant to corrosion.

Description

technical field [0001] The invention belongs to the field of civil engineering rock and soil, and in particular relates to a composite material grid structure reinforced concrete composite pile and a construction method thereof. Background technique [0002] The pile foundation in marine engineering not only supports the upper structure, but also resists the buoyancy force of seawater on the structure and seawater corrosion. Chinese patent CN101343870 discloses a fiber-reinforced composite reinforced concrete pile and its manufacturing and construction methods, which can be used for foundation reinforcement in marine island and reef environments. However, the temperature effects of different materials are different, and composite piles are often used during use. The phenomenon of delamination between materials occurs, resulting in a decrease in the bearing capacity of the pile (Pando 2003). Therefore, it is very important to increase the bite force between the reinforced co...
