Glass fiber-reinforced polymer concrete segment of shield tunnel lining and manufacturing method of glass fiber reinforced concrete segment

Abstract

The invention discloses a shield tunnel lining glass fiber reinforced concrete segment and a manufacturing method thereof, which relate to the technical field of tunnel construction. It includes concrete and fiberglass cages. Concrete is poured in the fiberglass cages. Connection holes and hoisting holes are provided on the concrete surface. Rectangular fiberglass reinforcement, rectangular fiberglass reinforcement with curvature, fiberglass reinforcement with curvature, Rectangular fiberglass reinforcement is used as the main fiberglass reinforcement to weave into the main body of the fiberglass cage. Triangular fiberglass reinforcement and square fiberglass reinforcement are supported between the main bodies. The short glass fiber bars are fixed, and the connection between the glass fiber bars is fixed as a whole by the glass fiber bars for binding. The invention has high strength, light weight, low cost, oxygen resistance and corrosion resistance, greatly improves the service life of the segments, and improves the construction progress of the construction method.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a shield tunnel lining glass fiber reinforced concrete segment and a manufacturing method. Background technique [0002] As the world's advanced underground tunnel construction technology - shield tunneling method, it has the advantages of fast construction speed, high lining quality, and small impact on the environment, and is widely used in current underground construction projects. As an important lining component, the production process of the prefabricated segment of the shield tunnel develops along with the tunnel construction technology, especially the development of the shield construction technology. The shield segment is the main assembly component of the shield construction and the most important part of the tunnel. The inner barrier is responsible for resisting soil pressure, groundwater pressure and some special loads. The shield segment is the permanent...

AI Technical Summary

Problems solved by technology

Metal segments have high cost, heavy weight, poor oxidation and corrosion resistance, and due to their metal properties, the construction progress of shield tunneling construction is slow. Based on this, it is particularly necessary to design a shield tunnel lining glass fiber reinforced concrete segment and its manufacturing method
