FRP membrane shell for reinforcing bridge pier and pile foundation and underwater structure reinforcing construction method
The invention provides an FRP (fiber reinforced plastic) membrane shell for reinforcing bridge piers and pile foundations. The FRP membrane shell is of a cylindrical structure formed by splicing a plurality of prefabricated FRP pipe pieces through quick connecting hasps at the edges of the pipe pieces, and each FRP pipe piece is provided with a fiber cloth outer layer, a grid middle layer and resin filled in the fiber cloth and grids. The membrane shell is applied to underwater structure reinforcing construction, wherein the FRP membrane shell is assembled above the water surface through the quick connecting hasps, sinks to surround underwater piers and pile foundations and is filled with concrete. By means of the advantages of light weight, corrosion resistance, easiness in forming and the like of the FRP, the FRP is applied to underwater structure reinforcement, so that the pier and pile foundation reinforcement construction efficiency is improved, and the bearing capacity, the anti-seismic property and the durability of the pier are also enhanced.
本发明提供一种用于桥墩、桩基加固的FRP膜壳，由若干预制FRP管片，经管片边缘的快速连接搭扣拼接组成的筒状结构，FRP管片具有纤维布外层和网格中间层，以及填充于纤维布及网格内的树脂。该膜壳应用在水下结构加固施工中，利用快速连接搭扣在水面以上拼装FRP膜壳，下沉包围水下桥墩、桩基并填充混凝土。本发明充分利用FRP轻质、耐腐蚀、易成型等优点，应用在水下结构加固中，既提升了桥墩、桩基加固施工的效率，又增强了桥墩的承载力、抗震性能和耐久性能。
