Problems solved by technology
The carbon fiber reinforcement method has good strength and strong corrosion resistance, but the cost is high, the price fluctuates greatly, and it will cause environmental pollution during the production process, which does not conform to the concept of green development
At present, hydraulic structures such as wharves and bridges are subject to long-term water erosion and adverse weather conditions, and beams, slabs, and column structures will have cracks to varying degrees. Once the cracks are not resolved in time, the safety of the structure will be threatened. , will bring greater economic loss

Abstract
The invention discloses a structure for reinforcing a beam plate column by adopting a basalt fiber grid system and a construction method. The construction method comprises the following steps: carrying out base layer treatment on a concrete structure; cleaning a construction surface; spraying an interface agent; constructing a basalt fiber grid; special mortar is sprayed; the special mortar curing period is finished, and reinforcement is completed. The structure comprises a basalt fiber grid installed on the surface of a concrete structure, and special mortar is arranged between the basalt fiber grid and the concrete structure and on the surface of the basalt fiber grid. The method is simple in construction process, and the ends do not need to be additionally treated; the basalt fiber grid has excellent long-term durability, and long-term service of a reinforcing system can be guaranteed; after the method is adopted to reinforce and repair beam, plate and column structures in the hydraulic environment field, rerepair is not needed, and the maintenance cost is saved.
Description
technical field [0001] The application belongs to the technical field of hydraulic structure concrete structures, and in particular, relates to a structure and a construction method for reinforcing beam-slab-column using a basalt fiber grid system. Background technique [0002] Conventional engineering structure reinforcement methods include increasing section reinforcement method, externally bonded steel reinforcement method, additional fulcrum reinforcement method, carbon fiber reinforcement method, etc. In addition to meeting the structural strength requirements, the corrosion resistance and durability of hydraulic structures also consider the structural life. Important indicators. The carbon fiber reinforcement method has good strength and strong corrosion resistance, but the cost is high, the price fluctuates greatly, and it will cause environmental pollution in the production process, which is not in line with the concept of green development. At present, hydraulic st...
