The core differential advantage of this GFRP anti-floating anchor rod lies in its excellent anti-corrosion performance. Compared with steel anchor rods, no additional anti-corrosion coating is required, and it can be used stably for a long time in strong corrosion environments such as saline-alkali land, coastal intertidal zones and chemical parks, without rust, expansion and other problems. The lightweight design makes the weight of a single anchor rod only 25% of that of a steel anchor rod with the same bearing capacity, greatly reducing the labor demand for on-site hoisting and installation, and simplifying the construction process. No special tensioning equipment is required for installation, and the construction can be completed with conventional grouting process. The product also has excellent electrical insulation performance, avoiding electromagnetic interference caused by traditional steel anchor rods, suitable for underground buildings with weak current systems and lightning protection grounding requirements. In addition, the product has passed ISO14001 and CE certification, complying with international environmental protection and construction standards, providing reliable product guarantee for overseas projects.
The main body of this product is made of E-glass fiber reinforced epoxy resin, with a diameter range of 16mm to 32mm, the conventional single length is 4m to 12m, and can be customized according to project needs. The ultimate tensile strength is ≥800MPa, and the uplift bearing capacity ranges from 100kN to 280kN, adapting to the anti-floating needs of small and medium-sized underground buildings. The product adopts continuous fiber winding forming process, with a fiber content of up to 75%, ensuring uniform and stable structural strength. In terms of anti-corrosion performance, it completely resists corrosion from salt spray, alkaline soil and chemical solvents, without additional anti-corrosion treatment. The weight of a single product ranges from 3kg to 12kg, and the packaging adopts reel packaging, which is convenient for transportation and on-site放线 installation. Only conventional grouting process is required for installation, no special tensioning equipment is required, and the construction speed is increased by more than 40% compared with steel anchor rods.
This GFRP anti-floating anchor rod is mainly suitable for underground engineering in strong corrosion environments such as coastal saline-alkali land, chemical parks and coastal intertidal zones, including coastal urban underground parking lots, underground storage areas of chemical enterprises, underground structures of sewage treatment plants and other scenarios. At the same time, due to its excellent electrical insulation performance, it is also suitable for underground buildings with weak current systems and lightning protection grounding requirements, such as urban underground comprehensive pipe corridors and underground computer rooms of data centers. In addition, the product can also be used for anti-floating support of wind power generation foundations and underground structure reinforcement of island wharves. Compared with traditional steel anchor rods, this product does not require regular anti-corrosion maintenance, greatly reducing the operating costs of the entire life cycle of the project, and conforming to the development concept of green buildings.
