As shown in fig. 1, a schematic structural diagram of a detachably connected supporting device provided in the embodiment of the present application is shown, the supporting device includes at least one arched beam 10, and each arched beam 10 is configured 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 deformation beam 12 is detachably connected to the side wing beam 20.

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 application, the side wing beams 20 are detachably connected with the deformed beams 12 at two ends of the arched beam 10, so that the transportation and installation of the supporting equipment are facilitated.

In the embodiment of the application, the arched beam 10 comprises an arched beam 11 and deformed beams 12 arranged at two ends of the arched beam 11, the deformed beams 12 change the original extending direction of the arched beam 10, so that two ends of the arched beam 10, namely the deformed beams 12, extend towards the side top 101 of the tunnel surrounding rock 100, the horizontal length of the arched beam 10 is prolonged, further the side wing beams 20 are close to the side walls 102 of the tunnel surrounding rock 100 as far as possible, and the tunnel space after supporting, particularly the effective space in the middle of the tunnel after supporting, is obviously 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.

In one embodiment of the present application, the deformation beam 12 extends outwardly away from one end of the arc beam 11 and is removably attached to 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 wing beams 20. One end of the cross beam extends horizontally outward compared to the arched beam 11 until it is connected to the upwardly extending side wing beam 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.

One end of the deformation beam 12 far away from the arc beam 11 is used for supporting a side top 101 or a side upper 102 of the tunnel; as shown in fig. 1, the side beams 20 are vertically installed in a direction perpendicular to the horizontal plane of the tunnel, the deformed beams 12 of the arched beams 10 change the original arc-shaped extension direction of the arched beams 10, the deformed beams 12 extend toward the side top 101 of the tunnel surrounding rock 100 and contact with the side top 101 or the side wall 102, and the outer side profiles of the deformed beams 12 match the inner wall profiles of the side top 101. 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; moreover, the deformation beam 12 is in contact with the roof 101 or the side wall 102, and functions to support the roof 101 or the side wall 102 of the tunnel. Of course, in the case where the connection beam 50 supports the lateral roof 101 or the lateral wall 102 of the tunnel surrounding rock 100, the deformation beam 12 is directly connected to the connection beam 50 without contacting the lateral roof 101 or the lateral wall 102 of the tunnel surrounding rock 100.

Compared with the arched beam in the prior art, the deformed beam 12 of the arched beam 10 in the supporting device in the embodiment of the application can directly support the side top 101 of the tunnel, the outer side surface profile of the deformed beam 12 is matched with the inner wall profile of the side top 101, the contact area between the deformed beam 12 and the side top 101 is guaranteed, the arched beam 10 in the supporting device in the embodiment of the application can play a role of supporting the side top 101 of the surrounding rock, and the stability of the surrounding rock and the supporting device is enhanced.

The deformation beam 12 and the side wing beam 20 are detachably connected in an inserting mode. Specifically, the deformation beam 12 is provided with an insertion port matched with the end shape of the side wing beam 20, and the side wing beam 20 is inserted into the insertion port, so that the detachable connection of the deformation beam 12 and the side wing beam 20 is realized.

In the field installation process, in order to further ensure the stability of the deformation beam 12 and the side wing beam 20 after installation, a plurality of through pins 60 penetrating through the deformation beam 12 and the side wing beam 20 are required to be arranged, and the deformation beam 12 and the side wing beam 20 are further locked through the through pins 60; when the deformation beam 12 and the side wing beam 20 need to be disassembled, the through pin 60 is pulled out, and the side wing beam 20 is pulled out from the plug-in port of the deformation beam 12, so that the deformation beam 12 and the side wing beam 20 can be disassembled. Of course, the socket may also penetrate through the deformation beam 12, so that the side wing beam 20 may penetrate through the deformation beam 12, and the deformation beam 12 and the side wing beam 20 are locked by the penetrating pin 60, thereby achieving the purpose that the side wing beam 20 supports the side top 101 of the tunnel surrounding rock 100 or the top of the surrounding rock 100.

It should be noted that the insertion port may also be disposed on the side wing beam 20, and the deformation beam 12 is inserted into the insertion port. The position of the interface can be set according to actual requirements.

The deformation beam 12 and the side wing beam 20 can also be detachably connected in other ways. Specifically, the deformation beam 12 is provided with a connecting member, and the side wing beam 20 is provided with a clamping joint matched with the connecting member. In the embodiment of the present application, the connecting member may be a clamping band, and the clamping joint may be a clamping band head matched with the clamping band, so as to detachably connect the deformation beam 12 and the side wing beam 20 by means of the clamping band. Of course, the connecting piece is also a flange, and the clamping joint can be a bolt matched with the clamping belt, so that the deformation beam 12 is detachably connected with the side wing beam 20 in a flange connection mode.

In order to further ensure the stability of the deformed beam 12 and the side wing beam 20 after installation, a plurality of pins 60 penetrating through the deformed beam 12 and the side wing beam 20 may be provided, and the deformed beam 12 and the side wing beam 20 are further locked by the pins 60.

It should be noted that the side beam 20 may also be provided with a clamping groove, and the deformation beam 12 is provided with a clamping head matched with the clamping groove. The positions of the clamping groove and the clamping head can be set according to actual requirements.

It should be further 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 connection position of 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 supported tunnel is enlarged, and the effective lengths of the supporting columns 40 and the side wing beam 20 can be ensured to be increased, thereby increasing the extension and retraction stroke of the supporting columns.

In an embodiment of the present application, if the natural stability of the sidewall 102 of the tunnel surrounding rock 100 is not good, the sidewall 102 needs to be supported by the supporting equipment, and at this time, the outer side of the side spar 20 of the supporting equipment can be attached to the sidewall 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.

Specifically, as shown in fig. 2, the deformation beam 12 includes a transition section 121 and an arc-shaped section 122, the transition section 121 is connected to the arc-shaped section 122, and one end of the transition section 121 away from the arc-shaped section 122 is connected to the arc-shaped beam 122; one end of the arc-shaped section 122 far away from the transition section 121 is used for being attached to the side top 101 or the side upper 102 of the tunnel; the curvature of the outer side of the arc-shaped section 122 is matched with the curvature of the side top 101 or the side upper 102. 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.

The deformed beams 12 of the arched beams 10 change the original curved extension direction of the arched beams 10, and the deformed beams 12 extend toward the lateral roof 101 of the tunnel surrounding rock 100 until they contact the wing beams 20 vertically installed in a direction perpendicular to the horizontal plane of the tunnel. The arc-shaped section 122 of the deformation beam 12 is connected with the side wing beam 20, and the arc-shaped section 122 is partially contacted with the side top 101 or the side wall 102 of the tunnel surrounding rock 100. Moreover, the curvature of the outer side of arc 122 is adapted to the curvature of either side top 101 or side top 102, where the outer side of arc 122 refers to the surface of arc 122 that contacts side top 101 and side top 102. In the practical application process, according to the requirements of the engineering, the connection beam 50 needs to be arranged between the arc-shaped section 122 and the side top 101 or the side wall 102 of the tunnel surrounding rock 100, and at this time, the arc-shaped section 122 of the deformation beam 12 may not be in contact with the side top 101 or the side wall 102 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. Meanwhile, in the embodiment of the present application, both the arc-shaped section 122 of the deformation beam 12 and the arc-shaped section 122 of the arched beam 10 may serve to support the side roof 101 or the side wall 102.

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.

It should be noted that the insertion port may also be disposed on the side wing beam 20, and the arc-shaped section 122 of the deformation beam 12 is inserted into the insertion port. The position of the interface can be set according to actual requirements.
