In tunnel lining projects, the use of dedicated wet spraying manipulators has many technical advantages, which greatly improves the construction quality and efficiency. The following are the main technical advantages of wet spraying manipulators for tunnel lining:
1. Simplify the process and improve visibility
In traditional tunnel lining construction, the pre-buried pipe and grouting construction process is complicated, there are many hidden projects, and it is difficult to monitor the quality. By simplifying the pre-buried pipe and grouting process, improving the grouting tooling, and using repair grouting binders, the lining vault casting is transformed from a hidden project to a "visible" project, effectively preventing the occurrence of lining vault defects. In addition, the use of micro-expansion grouting binders can repair construction gaps, cold joints, and concrete non-compactness, thereby improving the overall construction quality.
2. Waterproof function
Waterproofing is a key issue in the tunnel construction process. Through the grouting process, the slurry can penetrate into the damaged part of the waterproof board to form a "mushroom" type embolism, which effectively blocks the water flow. This water blocking function can not only improve the waterproof performance of the tunnel, but also extend the service life of the tunnel and reduce the cost of later maintenance.
3. Multifunctional integrated equipment
The wet spraying manipulator dedicated to tunnel lining integrates slurry making, slurry storage and grouting, and has a high grouting pressure. High-pressure grouting can overcome the pipeline resistance of low water-to-material ratio slurry and the resistance of vertical transportation of slurry, so that the slurry can be evenly distributed in the construction site, ensuring the density and uniformity of grouting.
4. Safe and reliable construction
Using the support of the lining trolley, low water-to-material ratio grouting is carried out under high grouting pressure to ensure that the grouting material is fully dense and the construction process is safe and reliable. High-pressure grouting not only improves construction efficiency, but also reduces errors in human operation and ensures construction quality.
The wet spraying manipulator dedicated to tunnel lining has significant advantages in simplifying the process, improving construction quality, waterproof performance, construction safety and flexibility, and provides strong technical support for the efficient and high-quality construction of tunnel projects.
