The invention provides a thick wall glass fiber reinforced plastic corrugated plate provided with connecting flanges on the periphery and a splicing method thereof and belongs to the technical field of glass fiber reinforced plastic corrugated plate splicing. The thick wall glass fiber reinforced plastic corrugated plate comprises a glass fiber reinforced plastic corrugated plate structure, a sealing flange connecting structure and a reinforcing structure. The thick wall glass fiber reinforced plastic corrugated plate is convenient to manufacture, simple in structure, high in overall strengthand carrying capacity, rapid in construction, high in resistance to chemical attack, long in service life, lower in overall cost, low in maintaining cost and fewer in potential safety hazard, is suitable for professional batch production in a factory, can be widely applied to culvert passages, pipeline splicing, existing bridge repairing, tunnel reinforcing, comprehensive pipe galleries and otherprojects, is an ideal substitute product of existing armored concrete structures and corrugated steel plate structures and is suitable for pipe-jacking construction and shield construction.
Description
technical field [0001] The invention belongs to the technical field of splicing of FRP corrugated plates, and more specifically relates to thick-walled FRP corrugated plates with connecting flanges around them and a splicing method thereof. Background technique [0002] FRP corrugated board is a new type of building material, and it has been used in the roof of buildings. However, most of the applications in this area are thin-walled FRP corrugated boards, and the connection method is mostly direct punching connection. The strength is low and the use is limited. At present, the market There is a corrugated steel structure made of steel plates, which can replace the cement structure and be used in culvert passages, splicing pipes, old bridge repairs, tunnel reinforcement, comprehensive pipe corridors and other projects. Although the corrugated steel structure is better than the cement structure in various performance With a greater degree of improvement, the cost has also bee...
