Rock-soil tunnel foundation pit supporting structure stable in supporting

HE YONGHONG / JIN PENGWEI

The invention discloses a steadily-supported rock-soil tunnel foundation pit supporting structure, and relates to the technical field of tunnel foundation pit supporting structures.The steadily-supported rock-soil tunnel foundation pit supporting structure comprises a cavity base and a buffer plate, and a servo motor is mounted on the inner bottom wall of the cavity base; the output end of the servo motor is provided with a gear which is concentric with the axis of the output end of the servo motor, and the gear is meshed with a rack rod through teeth. According to the rock-soil tunnel foundation pit supporting structure stable in supporting, through arrangement of a servo motor, a gear, a rack rod, a convex sliding block, an adjusting plate and an extending rod, the rock-soil tunnel foundation pit supporting structure stable in supporting has the effect of conveniently adjusting and extending the supporting distance, through cooperation of the gear and the rack rod, a supporting plate and a buffering plate can be conveniently and outwards extended, and the supporting effect is improved. The supporting plate is convenient to use and suitable for tunnel foundation pits of various specifications, the application range is large, the clamping blocks and the round rods are matched, the supporting stability of the supporting plate is improved, and the purpose of improving practicability is achieved.
