In the process of soft surrounding rock tunnel excavation and support, it is usually necessary to set lock foot anchor rods on both sides of the support steel frame in the side wall range to enhance the stability of the primary support structure and prevent arch foot shrinkage and arch collapse. The connection effect of the lock foot anchor rod and the support steel frame is very critical.

[0003] According to the application number CN202222845949.4, a new type of assembly type lock foot anchor rod and support steel frame connector is proposed, which belongs to the field of tunnel construction technology. The outer frame is provided with through holes on the opposite two edges, and the through holes are rotatably connected with nuts inside. The inside of the nut is provided with a screw rod connected with it by screw thread. One end of the screw rod extends into the outer frame and is connected with the clamping block. This application directly welds the outer frame with the support steel frame, which results in that the distance between the outer frame and the support steel frame cannot be changed after the outer frame limits the lock foot anchor rod, and cannot be adjusted according to the use. Therefore, we propose an assembly type lock foot anchor rod and support steel frame connector. UTILITY MODEL CONTENTS
