Description

Technical Field

[0001] This utility model relates to the field of tunnel engineering technology, specifically to a support component for tunnel grouting reinforcement. Background Technology

[0002] In tunnel construction, providing effective support for the sections inside the tunnel that require grouting is a crucial step in ensuring the effectiveness of grouting reinforcement and construction safety.

[0003] Traditional tunnel grouting support structures mostly use rigid support components with fixed shapes and sizes, which are difficult to adapt to tunnels with different curvatures and cross-sectional dimensions. For example, in tunnel areas with large curvatures or irregular cross-sections, the support components of the fixed structure cannot fit tightly against the tunnel sidewalls, resulting in uneven distribution of support force and easy local stress concentration. This not only reduces the reinforcement effect of the grouting part, but may also cause safety hazards such as deformation of the surrounding rock or even collapse.

[0004] In addition, the existing support components often require a lot of auxiliary tools and complicated operating procedures during disassembly and assembly, which is time-consuming and labor-intensive. In particular, when different specifications of support components need to be replaced for different construction scenarios, the inconvenience of disassembly and assembly is particularly prominent, which greatly affects construction efficiency and increases construction costs. Moreover, most support structures do not have flexible adjustment functions and cannot be adjusted in real time according to the actual geological conditions of the tunnel and grouting requirements, making it difficult to ensure safety and stability during construction.

[0005] Therefore, it is necessary to propose a support component for tunnel grouting reinforcement. Utility Model Content
