Problems solved by technology
[0003] For highway tunnels built with extruded expansive rock, smart devices are usually required to support the dome and side walls. Due to the variability of expansive rock, existing support devices cannot effectively support the tunnel according to the volume change of expansive rock. , and the supporting device cannot support different types of tunnels

Embodiment
[0025] Such as Figure 1-4 As shown, a support device for extruded expansive rock road tunnels includes two support plates 1, and the upper side walls of the two support plates 1 are fixedly connected with a first rubber pad 2, wherein the two support plates 1 are fixedly connected to the On the ground of the tunnel, the first rubber pad 2 is in contact with the side wall of the tunnel, and the volume change of the expansive rock on the side wall of the tunnel can be buffered by the first rubber pad 2, so that the first rubber pad 2 is always pressed against the side wall of the tunnel , the upper ends of the two support plates 1 are fixedly connected with the first arc-shaped plate 3, the upper end of the first arc-shaped plate 3 is provided with a groove 4, and the inner wall of the groove 4 is slidably connected with a connecting mechanism 5, and the two connecting mechanisms 5 A second arc-shaped plate 6 is fixedly connected to one end outside the groove 4, a buffer mechan...

The invention belongs to the technical field of tunnel supporting devices, and particularly relates to an extrusion swelling rock highway tunnel supporting device. The extrusion swelling rock highwaytunnel supporting device comprises two supporting plates, first rubber pads are fixedly connected to the upper parts of the side walls of the two supporting plates, first arc-shaped plates are fixedlyconnected to the upper ends of the two supporting plates, grooves are formed in the upper ends of the first arc-shaped plates, and connecting mechanisms are slidably connected to the inner walls of the grooves. A second arc-shaped plate is fixedly connected to the positions, located at one ends of the outside of the grooves, of the two connecting mechanisms, and buffering mechanisms are fixedly connected to the second arc-shaped plate and the arc-shaped outer side walls of the first arc-shaped plates. An adjusting mechanism is arranged between the two supporting plates, the left end and the right end of the adjusting mechanism are separately and fixedly connected with the side walls of the two supporting plates, a lifting mechanism is fixedly connected to the upper end of the adjusting mechanism, and the upper end of the lifting mechanism is fixedly connected with the lower end of the second arc-shaped plate. The extrusion swelling rock highway tunnel supporting device has the advantages that a swelling rock tunnel can be effectively supported, and the extrusion swelling rock highway tunnel supporting device can be further used for tunnels with different types.
Description
technical field [0001] The invention belongs to the technical field of tunnel support devices, in particular to a support device for extruded expansive rock highway tunnels. Background technique [0002] Expansive rocks are a special type of soft rock. Its properties are rock-like but not rock-like, soil-like but not soil-like, and have a very close relationship with water. Very strong hydrophilicity. Because it contains a large amount of hydrophilic minerals, there will be a large volume change when the humidity changes, and a large internal stress will be generated when the deformation is restrained. That's why it's called expansive rock. [0003] For highway tunnels built with extruded expansive rock, smart devices are usually required to support the dome and side walls. Due to the variability of expansive rock, existing support devices cannot effectively support the tunnel according to the volume change of expansive rock. , and the supporting device cannot support di...
