The following describes the technical solutions of the present application and how to solve the above technical problems with specific embodiments.

As shown in fig. 1, a schematic structural diagram of a supporting device with a deformed beam provided by the embodiment of the present application is provided, the supporting device comprises at least one arched beam 10, and each arched beam 10 is provided with two side spars 20; the arched beam 10 comprises an arched beam 11 and deformation beams 12 arranged at two ends of the arched beam 11; the top section 21 of the side spar 20 is connected to the deformation beam 12.

In the supporting equipment provided by the embodiment of the application, the inner side surface of the top section of the side wing beam is connected with the deformed beam of the arched beam, so that the supported tunnel space, particularly the effective space in the middle of the supported tunnel is obviously enlarged, and the technical problems that the supported tunnel space is reduced and the supported tunnel space cannot be effectively enlarged in the prior art are solved.

Specifically, in the prior art, the arched beam of the tunnel supporting shed and the vertical side wing beam are integrally formed, and the arched beam and the side wing beam are connected in a smooth transition manner, that is, the arched beam changes into a vertical downward direction along with the tangent change of an arch shape and a straight line, and is connected with the vertical side wing beam. In the embodiment of the present application, the arched beam 10 includes an arched beam 11 and a deformation beam 12 disposed at one end of the arched beam 11, the deformation beam 12 changes the original extending direction of the arched beam 10, so that two ends of the arched beam 10, that is, the deformation beam 12, extend toward the side top 101 of the tunnel surrounding rock 100, the deformation beam 12 is connected to the inner side of the top section 21, and further the side wing beam 20 is as close as possible to the side wall 102 of the tunnel surrounding rock 100, so that the tunnel space after supporting, especially the effective space in the middle of the tunnel after supporting, is significantly enlarged.

In the embodiment of the present application, the shape of the surrounding rock 100 shown in fig. 1 is not limited to the shape intended by the present application, and the outline of the surrounding rock 100 is only used to illustrate the positional relationship and the contact connection relationship between each component of the supporting device provided in the tunnel of the surrounding rock 100 and the surrounding rock 100.

It should be noted that, as shown in fig. 1, in the supporting apparatus of the embodiment of the present application, the outer side surface of the top section 21 of the wing beam 20 contacts with the side roof 101 of the tunnel surrounding rock 100, so as to support the side roof 101 of the tunnel, and in the embodiment of the present application, the profile of the outer side surface of the top section 21 of the wing beam 20 matches with the profile of the inner wall of the side roof 101, so that the outer side surface of the top section 21 is maximally attached to the inner wall of the side roof 101, the effect of the wing beam 20 supporting the side roof 101 of the tunnel is further improved, and the stability of the surrounding rock and the supporting apparatus is enhanced. In practical application, sometimes, according to the requirements of engineering, the connection beam 50 needs to be disposed between the top section 21 of the side beam 20 and the side top 101 of the tunnel surrounding rock 100, and at this time, the outer side surface of the top section 21 of the side beam 20 is not in contact with the side top 101 of the tunnel surrounding rock 100.

In one embodiment of the present application, the deformation beam 12 extends outwardly away from one end of the arc beam 11 and is connected to the top section 21 of the side sill 20. As shown in fig. 1, the joists 12 in the support device are embodied as cross-beams having a rectangular cross-section, the ends of the cross-beams remote from the arc-beams 11 extending horizontally outwards and being connected to the top sections 21 of the wing beams 20. One end of the cross beam extends horizontally outward compared to the curved beam 11 until it is connected to the top section 21 of the upwardly extending side sill 20. Of course, the deformation beam 12 may also extend obliquely outwards, i.e. the deformation beam 12 extends simultaneously towards the bottom surface of the tunnel while extending outwards. It should be noted that, in the embodiment of the present application, the outward extension means that the deformation beam 12 extends toward the side top 101 or the side wall 102 of the tunnel surrounding rock 100, as shown in fig. 1, the tunnel in which the supporting equipment is located is the inside, and the surrounding rock 100 around the tunnel is the outside.

As shown in fig. 1, the wing beams 20 are vertically installed in a direction perpendicular to the horizontal plane of the tunnel, and the top section 21 is in contact with the side top 101 of the tunnel wall rock 100; the deformed beam 12 of the arched beam 10 changes the original arc-shaped extension direction of the arched beam 10, and the deformed beam 12 extends towards the side top 101 of the tunnel surrounding rock 100 and is connected with the inner side surface of the top section 21. Compared with the supporting equipment in the prior art, the projection length of the arched beam 10 in the direction parallel to the horizontal plane of the tunnel is increased, so that the tunnel space after being supported by the supporting equipment in the embodiment of the application is obviously enlarged. Of course, in the case where the connection beam 50 supports the side roof 101 of the tunnel surrounding rock 100, the roof section 21 is directly in contact with the connection beam 50, not in contact with the side roof 101 of the tunnel surrounding rock 100.

It should be noted that, when the geological conditions of the tunnel surrounding rock 100 are good, especially when the natural stability of the side wall 102 is good, at this time, the side wall 102 of the tunnel surrounding rock 100 is not required to be supported by supporting equipment, as shown in fig. 1, a certain gap is provided between the side wing beam 20 and the side wall 102 of the supporting equipment, so that the joint between the side wing beam 20 and the arched beam 10 can be ensured to be at a higher position as much as possible, so that the effective space in the middle of the tunnel after being supported and expanded can be ensured, and the effective lengths of the supporting columns 40 and the side wing beam 20 can be increased, thereby increasing the extension stroke of the supporting columns.

Simultaneously, compare in prior art flank roof beam, the top segment of the flank roof beam among the support equipment of this application embodiment can play the effect of the side top of direct support tunnel, and the outer side profile of top segment and the inner wall profile phase-match of side top have ensured the area of contact of top segment with the side top, and the side wing spar among the support equipment of this application embodiment can play the effect of supporting the country rock side top, has strengthened the stability of support equipment.

As shown in fig. 2, in the embodiment of the present application, one end of the deformation beam 12 extends horizontally outwards away from the arc beam 11 and is connected with the side top 101 of the tunnel surrounding rock 100 in a contact manner, and one end of the deformation beam 12 extends horizontally outwards compared with the arc beam 11 until being connected with the side top 101 of the tunnel surrounding rock 100 in a contact manner, and the upwardly extending side wing beam 20 abuts against the deformation beam 12, in this case, the side wing beam 20 does not contact the side top 101 of the tunnel surrounding rock 100.

As shown in fig. 3, in the embodiment of the present application, one end of the deformation beam 12 far from the arc beam 11 extends horizontally outwards, and during the extension process, in order to ensure the flatness of the contact surface between the deformation beam 12 and the side wing beam 20, the lower surface of the deformation beam 12 is parallel to the horizontal plane of the tunnel, and the upper surface of the deformation beam 12 has a certain radian to ensure the natural transition between the arc beam 11 and the deformation beam 12 without contacting the surrounding rock.

One end of the deformation beam 12 extends horizontally outwards until the deformation beam is connected with and in contact with the side top 101 of the tunnel surrounding rock 100 or a certain working gap is reserved between the deformation beam 12 and the side top 101, and the side wing beam 20 extending upwards abuts against the deformation beam 12, in this case, the side wing beam 20 cannot be in contact with the side top 101 of the tunnel surrounding rock 100.

Of course, if the natural stability of the side wall 102 of the tunnel surrounding rock 100 is not good, the side wall 102 needs to be supported by the supporting equipment, and at this time, the outer side of the side wing beam 20 of the supporting equipment can be attached to the side wall 102 of the tunnel. In this case, in order to secure a space in the middle of the tunnel after the support can be enlarged, the concrete form of the deformed beam 12 needs to be redesigned. The following description will be made in detail with reference to fig. 4.

In one embodiment of the application, the deformation beam 12 in the bracing arrangement is at least partly used to support the side roof 101 of the tunnel, as shown in figure 4.

The deformation beam 12 comprises a transition section 121 and an arc-shaped section 122, the transition section 121 is connected with the arc-shaped section 122, and one end of the transition section 121 far away from the arc-shaped section 122 is connected with the arc-shaped beam 11; the end of the arc section 122 far away from the transition section 121 is connected with the inner side surface of the top section 21, and the radian of the outer side surface of the arc section 122 is matched with the radian of the side top 101. In the embodiment of the present application, the transition section 121 and the arc-shaped section 122 are integrally formed to form the deformation beam 12, and here, for convenience of describing the deformation beam 12 in detail, the deformation beam 12 is split into the transition section 121 and the arc-shaped section 122.

Specifically, as shown in fig. 4, the side-wing beams 20 are vertically installed in a direction perpendicular to the horizontal plane of the tunnel, and the top section 21 is in contact with the side top 101 of the tunnel surrounding rock 100; the deformation beam 12 of the arched beam 10 changes the original arc extending direction of the arched beam 10, the deformation beam 12 extends towards the side top 101 of the tunnel surrounding rock 100, the arc section 122 of the deformation beam 12 is connected with the inner side surface of the top section 21, and the arc section 122 is partially contacted with the side top 101 of the tunnel surrounding rock 100. Furthermore, the curvature of the outer side of the arc-shaped section 122 is adapted to the curvature of the side roof 101, where the outer side of the arc-shaped section 122 refers to the surface of the arc-shaped section 122 that is in contact with the side roof 101. In the practical application process, according to the engineering requirement, the connection beam 50 needs to be arranged between the arc-shaped section 122 and the side top 101 of the tunnel surrounding rock 100, and at this time, the arc-shaped section 122 of the deformation beam 12 is not in contact with the side top 101 of the tunnel surrounding rock 100.

Compared with the supporting equipment in the prior art, the projection length of the arched beam 10 in the direction parallel to the horizontal plane of the tunnel is increased, so that the space of the tunnel supported by the supporting equipment in the embodiment of the application is obviously enlarged. In the present embodiment, the top section 21 of the side sill 20 and the arcuate section 122 of the arched girder 10 both serve as supports for the side roof 101.

In the embodiment of the present application, the upper surface of the transition section 121 is parallel to the horizontal plane of the tunnel, and the lower surface has a certain curvature, so as to ensure the natural transition between the arc-shaped beam 11 and the transition section 121 and the arc-shaped section 122.

In the embodiment of the application, the outer side of the side wing beam 20 of the supporting equipment is attached to the side wall 102 of the tunnel and used for supporting the side wall 102, the specific form of the deformation beam 12 is set, and the transition section 121 and the arc section 122 are utilized, so that the side wing beam 20 of the supporting equipment expands the middle space of the supported tunnel while supporting the side wall 102, and meanwhile, the distance between the two side wing beams 20 connected with the same arched beam 10 of the supporting equipment is kept in a proper range, and the width of the supported tunnel is ensured. In the practical application process, according to the engineering requirement, a side wall beam (not shown in the figure) needs to be arranged between the side wall beam 20 and the side wall 102 of the tunnel surrounding rock 100, and at this time, the outer side surface of the side wall beam 20 is not in contact with the side wall 102 of the tunnel surrounding rock 100. In practice, the side beams or deformed beams do not need to be in contact with the side roofs 101 and the side walls 102 due to the good integrity of the surrounding rock 100.

It should be noted that, in the present embodiment, the arched beam 10 is formed by integrally forming the arched beam 11 and the deformation beam 12. Here, for convenience of describing the arched beam 10 in detail, the arched beam 10 is split into an arched beam 11 and a deformed beam 12.

It should be noted that in the embodiment of the present application, the form of the deformed beams 12 at both ends of the arc beam 11 of the same supporting device is not limited to the cross beam and any one of the transition section 121 and the arc section 122, and a combination of the cross beam and the shaped beam may also be adopted. For example, one end of the arc beam 11 is provided as a deformation beam 12 in the form of a beam, and the other end is provided with the deformation beam 12 including a transition section 121 and an arc section 122.

The first and second arc beams 111 and 112 of the arc beam 11 can be rotated about the connecting member 113 by providing the connecting member 113 so that the arc beam 11 can be moved at a certain angle inward or outward.

In one embodiment of the present application, as shown in fig. 1 to 4, the supporting apparatus is further provided with a telescoping mechanism 30, one end of the telescoping mechanism 30 is connected to the transformation beam 12 provided at one end of the arc beam 11, and the other end of the telescoping mechanism 30 is connected to the transformation beam 12 provided at the other end of the arc beam 11.

The telescopic mechanism 30 comprises a mounting base arranged on the deformation beam 12 or the arc beam 11 and a hydraulic telescopic column connected with the mounting base, and the telescopic function of the telescopic mechanism 30 is realized through the hydraulic telescopic column and the support force for outward expansion of the arc beam 10 is given.

In the embodiment of the present application, the supporting columns 40 specifically include hydraulic supporting columns, through which the side spars 20 are supported, and thus the arched beams 10 are supported, and at the same time, since the side spars 20 are partially in contact with the side roofs 101, the hydraulic supporting columns also play a role of supporting the tunnel side roofs 101.
