The working principle of the frame-type tunnel supporting structure 100 is as follows:
referring to fig. 1 to 6, the frame-type tunnel supporting structure 100 includes a plurality of base members 110 and a plurality of connectors 120; the outer circumferential surface of each base member 110 is provided with a plurality of protrusions 111 and a plurality of recesses 112; the plurality of convex parts 111 and the plurality of concave parts 112 are arranged along the axis of the base member 110 in a staggered manner, and each convex part 111 and each concave part 112 are annularly arranged around the axis of the base member 110; the plurality of base members 110 each extend in the extending direction of the tunnel and are sequentially disposed around the inner circumferential surface of the tunnel; the convex portion 111 of each base member 110 is fitted with the concave portion 112 of the adjacent base member 110; any two adjacent base members 110 are connected by a connector 120.
The plurality of base members 110 are sequentially arranged around the inner circumferential surface of the tunnel, and any two adjacent base members 110 are connected through the connecting piece 120, so that the tunnel can be supported by the plurality of base members 110; in addition, in the process of realizing the supporting function of the plurality of foundation members 110, since the plurality of convex portions 111 and the plurality of concave portions 112 are arranged on the outer peripheral surface of each foundation member 110, the arrangement mode can increase the structural strength of each foundation member 110 through the arrangement of the convex portions 111 and the concave portions 112, and can absorb the deformation pressure of the surrounding rock through the deformation of the foundation members 110; also, by the protrusion 111 of each base member 110 being fitted with the recess 112 of the adjacent base member 110, the overall structural strength of the frame type tunnel supporting structure 100 can be increased.
To sum up, this frame-type tunnel supporting structure 100 can release country rock deformation pressure, reduces supporting structure's the internal force of structure to guarantee supporting structure's stability, thereby avoid supporting structure's damage, guarantee construction operation personnel's safety, and reduce the cost of construction.
Further, referring to fig. 1-6, in the present embodiment, when the protrusion 111 and the recess 112 of each base member 110 are disposed, the protrusion 111 may be disposed as an arc protrusion, and the recess 112 may be disposed as an arc recess. In such an arrangement, the structural strength of the base member 110 is increased; in addition, the arrangement can increase the contact area between the adjacent two base members 110, thereby improving the overall strength of the frame type tunnel supporting structure 100. Similarly, the corners of each protrusion 111 and each recess 112 are provided with a transition arc.
Incidentally, it is to be noted that the arrangement is such that the outer peripheral surface of each base member 110 is corrugated.
Further, referring to fig. 1-6, in the present embodiment, based on the above, the arc-shaped protrusions 111 and the arc-shaped recesses 112 are formed, so that when the base members 110 are disposed, each base member 110 is made of a steel corrugated plate, and each base member 110 can be a rectangular frame made of a steel corrugated plate. It should be noted that, under the condition that two adjacent base members 110 have contact surfaces that satisfy the use requirements, the structural shape of each base member 110 can be adaptively adjusted to adapt to different tunnel supports.
Referring to fig. 1 to 6, in the present embodiment, since the plurality of base members 110 extend in the extending direction of the tunnel and are sequentially disposed around the inner circumferential surface of the tunnel, when the plurality of base members 110 are rectangular members, after the plurality of base members 110 are sequentially disposed around the inner circumferential surface of the tunnel, a gap exists between two adjacent base members 110, and thus, in order to improve the contact stability of the two adjacent base members 110, the frame type tunnel supporting structure 100 further includes a plurality of fillers 130; each of the filling members 130 is used to fill a gap between two adjacent base members 110.
And after the plurality of foundation members 110 are connected to form the frame type tunnel supporting structure 100, the gap is relatively located at the outer side of the frame type tunnel supporting structure 100, and the gap gradually increases from the inside of the tunnel to the outside, so that when the filling is provided, in order to improve the wedging degree of the filling member 130 with the gap, the filling member 130 may be set to be wedge-shaped corresponding to the gap according to the structural shape of the adjacent two foundation members 110 and the formed gap profile.
Further, referring to fig. 1 to 6, in the present embodiment, the connecting members 120 are connecting bolts; in order to connect two adjacent base members 110 by the connecting bolt, therefore, a plurality of connecting holes 113 are formed on the abutting surface of each base member 110, which is used for being abutted against the adjacent base member 110, and the plurality of connecting holes 113 are sequentially arranged at intervals along the extending direction of the base member 110; each of the connection holes 113 is used to be in communication with the connection hole 113 of the adjacent base member 110 to mount the connection bolt. It should be noted that, since the convex portion 111 of each base member 110 is engaged with the concave portion 112 of the adjacent base member 110, when the connection holes 113 are provided, it is possible to locate a part of the connection holes 113 of each base member 110 at the convex portion 111 and locate the remaining part of the connection holes 113 at the concave portion 112. Thereby, the connection hole 113 on the convex portion 111 of each base member 110 is brought into corresponding conduction fit with the connection hole 113 on the concave portion 112 of the adjacent base member 110 to mount the connection bolt.
Further, referring to fig. 1 to 6, based on the above, it should be further noted that after the surrounding rock supported by the frame-type tunnel supporting structure 100 is stabilized, in order to improve the supporting stability of the frame-type tunnel supporting structure, the gap between any two adjacent foundation members 110 is filled with concrete. Therefore, the gap between any two adjacent base members 110 is of a solid structure, and the structural gap of the frame-type tunnel supporting structure 100 can be eliminated, so that the strength of the frame-type tunnel supporting structure can be improved, and the supporting stability is improved.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
