AI Technical Summary
Existing tunnel soft surrounding rock support devices are time-consuming and labor-intensive to install, are not securely installed, and have poor support effects.
The design employs a combination of pressure-distributing section, anchor cable section, and movable installation section. By dispersing the support force, the expansion structure of the anti-slip cylinder and bushing enables the rapid and secure installation of the anchor cable. Combined with the support of the arched frame and support plate, the stability and installation efficiency of the support device are improved.
This enabled the rapid and secure installation of anchor cables, improved the installation efficiency and support effect of the support device, and enhanced the stability and robustness of the surrounding rock passage.
