Description

Technical Field

[0001] The present invention relates to the technical field of road safety protection, and particularly relates to an anti-overturning steel shed tunnel structure. Background Art

[0002] In recent years, after multiple strong mountain earthquakes, high-position collapses and other geological disasters occurred, especially for the rush repair and traffic maintenance of mountain roads under complex terrain conditions, it has become a "lifeline" project. For the rush repair and traffic maintenance stage with extremely urgent time, the concrete shed tunnel cannot meet the requirements of "lifeline" rush repair and traffic maintenance because of its long construction period and high construction requirements. The traditional steel structure shed tunnel is of the "column + cross beam" type. Although its construction period is fast, its adaptability is poor. It can only adapt to steep slope sections (slopes with a gradient greater than 70°). If the inner slope is relatively gentle, due to the poor lateral anti-pushing ability of the "column + cross beam" structure, structural overturning is likely to occur. Once overturning occurs, the vehicles and personnel driving inside the shed tunnel are at risk of being buried. Therefore, the application of the steel structure shed tunnel is greatly restricted. Summary of the Invention

[0003] Aiming at the technical problem that the lateral anti-pushing ability of the above-mentioned steel structure shed tunnel is poor and structural overturning is likely to occur, restricting its application; the present invention provides an anti-overturning steel shed tunnel structure, which can prevent the shed tunnel from overturning during use, enabling the rush repair and traffic maintenance sections to quickly and safely apply the steel shed tunnel structure, thus ensuring the safety of mountain roads.

[0004] The present invention is realized through the following technical solutions:

[0005] An anti-overturning steel shed tunnel structure includes columns and cross beams, and also includes hinge seats and damping components; the hinge seats are used for fixedly connecting with the mountain body at the bottom of the shed tunnel, the lower ends of the columns are hinged to the hinge seats, enabling the columns to rotate along the direction of the mountain slope; one end of the damping component is used for hinging with the mountain body, and the other end of the damping component is hinged to the columns inside the shed tunnel structure.

[0006] When the present invention is in use, the hinge seats are fixed on the mountain body at the bottom of the shed tunnel, one end of the damping component is hinged to the mountain body opposite to the mountain side where the shed tunnel leans on, and then the columns and cross beams are assembled; when the mountain collapse and falling rocks impact one side of the shed tunnel facing the mountain body, rigid protection is carried out through the shed tunnel; if the impact force of the falling rocks is greater than the deflection moment of the columns, the columns will deflect. At the same time, the damping of the damping component is used to tension the shed tunnel to prevent the columns from rotating, thereby absorbing the impact of the falling rocks on the shed tunnel to prevent the shed tunnel from overturning. Therefore, the present invention can prevent the shed tunnel from overturning during use, enabling the rush repair and traffic maintenance sections to quickly and safely apply the steel shed tunnel structure, thus ensuring the safety of mountain roads. Among them, the shed tunnel is erected by using columns and cross beams. On the one hand, it is convenient for the quick installation of the shed tunnel. On the other hand, after the shed tunnel inclines, the damaged cross beams can be quickly replaced.

[0007] Further, it further includes side supports. The upper end of the side supports is connected to the columns outside the shed tunnel structure to support the outer columns when the deflection angle of the columns is too large, thereby forming a stable triangular support, further ensuring the overturning of the steel shed tunnel structure to protect the vehicles traveling in the shed tunnel.

[0008] As a specific implementation manner of the side supports, the side supports are telescopic hydraulic rods to adapt to columns with different inclination angles.

[0009] Further, the damping component is provided with a tensile force monitor to monitor the lateral thrust force received by the shed tunnel structure in real time, facilitating the judgment of the safety of the shed tunnel.

[0010] Preferably, the tensile force monitor is electrically connected to a warning device to warn passing vehicles when the lateral thrust force received by the shed tunnel structure is large.

[0011] Preferably, the side supports are controlled to expand and contract by the tensile force monitor to adjust the length of the side supports according to the magnitude of the lateral thrust force received by the shed tunnel, further ensuring the safety of the shed tunnel structure.

[0012] Preferably, the lower end of the side supports is provided with a flexible pad, which on the one hand reduces the requirements for the flatness of the road surface by the end face of the side supports, and on the other hand can also play a certain buffering role to prevent the side supports from damaging the road surface during support.

[0013] As a specific implementation manner of the damping component, the damping component includes a damper and a damping spring; one end of the damper is used for hinged connection with the mountain body, the other end of the damper is connected to the column through a tensile force monitor; one end of the damping spring is used for fixed connection with the mountain body, and the other end of the damping spring is connected to the column through a tensile force monitor.

[0014] As a specific implementation manner of the damper, the damper is a piston damper.

[0015] As a specific implementation manner of the connection between the column and the cross beam, the column and the cross beam are connected through a mortise and tenon structure, so that the simply supported beam can resist a certain lateral thrust force to avoid relative displacement between the cross beam and the column when the column is inclined, resulting in the disintegration of the shed tunnel.

[0016] The beneficial effects of the present invention:

[0017] 1. When rockfall strikes the side of the tunnel facing the mountain, the tunnel provides rigid protection. If the impact of the rockfall exceeds the deflection torque of the columns, the columns deflect. Simultaneously, the damping of the damping assembly tensions the tunnel, preventing its rotation. This absorbs the impact of the rockfall and prevents the tunnel from tipping over. This invention prevents the tunnel from tipping over during use, enabling the rapid and safe use of steel tunnel structures in emergency road maintenance, thus ensuring road safety in mountainous areas.

[0018] 2. The shed hole is constructed with columns and beams. On the one hand, it is convenient for the rapid installation of the shed hole. On the other hand, after the shed hole collapses, the damaged beams can be quickly replaced.

[0019] 3. The upper end of the side support is hinged to the column on the outside of the shed structure to support the outer column when the column deflection angle is too large, thereby forming a stable triangular support to further ensure that the steel shed structure will not overturn and protect the vehicles traveling in the shed.

[0020] 4. The damping assembly is equipped with a tension monitor to monitor the lateral thrust on the shed tunnel structure in real time, facilitating the determination of its safety. Furthermore, the tension monitor is electrically connected to an alarm to alert passing vehicles when the shed tunnel structure is subject to significant lateral thrust.

[0026] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with examples and drawings. The exemplary embodiments of the present invention and their descriptions are only used to explain the present invention and are not intended to limit the present invention.

[0027] Example

[0028] An anti-overturning steel shed tunnel structure includes columns 1 and crossbeams 2, and also includes hinge seats 3 and damping components 4; the hinge seats 3 are used for fixedly connecting with the mountain body 8 at the bottom of the shed tunnel, the lower ends of the columns 1 are hinged with the hinge seats 3, so that the columns 1 can rotate along the slope direction of the mountain body 8; one end of the damping component 4 is used for hinging with the mountain body 8, and the other end of the damping component 4 is hinged with the column 1 inside the shed tunnel structure.

[0029] Specifically, during use, on gentle slope terrain, the hinge seats 3 are fixed on the mountain body 8 at the bottom of the shed tunnel, such as fixing the hinge seats 3 on the mountain body 8 where the shed tunnel is erected through anchor bolts, friction piles, rock-socketed piles, etc.; at the same time, one end of the damping component 4 is hinged on the mountain body 8 directly opposite to the mountainside side of the shed tunnel, such as anchoring the anchor seat 9 on the mountain body 8 through an anchor rod, and then hinging one end of the damping component 4 with the anchor seat 9.

[0030] When the mountain body 8 collapses and falling rocks impact one side of the shed tunnel facing the mountain body 8, rigid protection is carried out through the shed tunnel; if the impact force of the falling rocks is greater than the deflection moment of the column 1, the column 1 will deflect. At the same time, the damping of the damping component 4 is used to tension the shed tunnel to prevent the column 1 from rotating, so as to absorb the impact of the falling rocks on the shed tunnel to prevent the shed tunnel from overturning. Among them, the shed tunnel is erected by using columns 1 and crossbeams 2. On the one hand, it is convenient for the rapid installation of the shed tunnel. On the other hand, after the shed tunnel is tilted, the damaged crossbeam 2 can be quickly replaced.

[0031] Further, it also includes side supports 5. The upper ends of the side supports 5 are connected to the columns 1 outside the shed tunnel structure to support the outer columns when the deflection angle of the columns 1 is too large, so as to form a stable triangular support, further ensuring the anti-overturning of the steel shed tunnel structure to protect the vehicles running inside the shed tunnel. Even if there are vehicles inside the shed tunnel structure, there will be no danger. It can be understood that the side supports 5 are fixedly connected or hinged to the columns 1 outside the shed tunnel structure. In this embodiment, to ensure the sufficient safety of the shed tunnel, the side supports 5 are fixedly connected to the columns 1 outside the shed tunnel structure. Usually, the included angle between the length direction of the side supports 5 and the length direction of the columns 1 is 30 - 45 degrees.

[0032] As a specific implementation manner of the side supports 5, the side supports 5 are telescopic hydraulic rods to adapt to columns 1 with different inclination angles.

[0033] Further, the damping component 4 is provided with a tension monitor 6 to monitor the lateral thrust force received by the shed tunnel structure in real time, which is convenient for judging whether the shed tunnel is safe. At the same time, the tension monitor 6 can communicate with the corresponding road construction and management departments through a communication module to issue road safety prompts.

[0034] Preferably, the tensile force monitor 6 is electrically connected to a warning device to warn passing vehicles when the lateral thrust on the shed tunnel structure is large. That is, when the impact energy is large, if the tensile force of the damping component 4 exceeds the set warning value, the tensile force monitor 6 issues an alarm through the warning device to notify passing vehicles, so that those not entering the shed tunnel are prohibited from entering, and those already in the shed tunnel drive away quickly.

[0035] Preferably, the side support member 5 is controlled to expand and contract by the tensile force monitor 6 to adjust the length of the side support member 5 according to the magnitude of the lateral thrust on the shed tunnel, further ensuring the safety of the shed tunnel structure. That is to say, based on the tensile force data monitored by the tensile force monitor 6, the hydraulic flow direction of the hydraulic rod is controlled, thereby controlling the elongation or shortening of the hydraulic rod.

[0036] Preferably, a flexible pad 7 is provided at the lower end of the side support member 5. On the one hand, it reduces the requirement for the flatness of the road surface by the end face of the side support member 5, and on the other hand, it can also play a certain buffering role to prevent the side support member 5 from damaging the road surface during support.

[0037] As a specific implementation manner of the damping component 4, the damping component 4 includes a damper 41 and a damping spring 42; one end of the damper 41 is used for hinged connection with the mountain body 8, and the other end of the damper 41 is connected to the column 1 through the tensile force monitor 6; one end of the damping spring 42 is used for fixed connection with the mountain body 8, and the other end of the damping spring 42 is connected to the column 1 through the tensile force monitor 6. In this embodiment, the damping spring 42 is sleeved outside the damper 41, and one end of the damping spring 42 is fixedly connected to the anchor seat 9 and the other end is fixedly connected to the tensile force monitor 6.

[0038] The working principle of this embodiment is as follows:

[0039] When the shed tunnel is installed on a gentle slope terrain, the collapsed falling rocks impact the column 1 of the steel shed tunnel. When the bending moment generated by the impact force on the column 1 is greater than the starting bending moment of the hinge seat 3 (including the structural moment of the connection between the column 1 and the cross beam 2 and the rotational resistance moment of the column 1 relative to the hinge seat 3), the column 1 rotates along the hinge axis on the hinge seat 3. At the same time, due to the tensile force on the damping component 4 (piston + damping spring cable) on the mountain side, it is tensioned to prevent the column 1 from rotating.

[0040] When the impact energy is large, the tensile force of the damping component 4 exceeds the set warning value. The tensile force monitor 6 issues an alarm through the warning device to notify passing vehicles. Those not entering the shed tunnel are prohibited from entering, and those already in the shed tunnel drive away quickly. And it notifies the corresponding road construction and management department through the communication module to issue a road safety reminder. At the same time, the telescopic hydraulic rod on the outside of the column 1 extends to provide support when the steel shed tunnel rotates, making it a geometrically invariant system, avoiding the overturning of the steel shed tunnel structure, and even if there are vehicles inside the shed tunnel structure, there will be no danger of being covered.

[0041] After the collapse of the falling rocks is cleared, the damper 41 and the damping spring 42 of the damping component 4 will contract, pulling the steel shed tunnel back to the structural form for normal use. At this time, the hydraulic rod also contracts to the normal state, and only the damaged cross beam or mortise needs to be replaced, so as to quickly protect the mountain roads.

[0042] The specific embodiments described above have further elaborated on the purpose, technical solutions, and beneficial effects of the present invention. It should be understood that the above description is only the specific embodiments of the present invention and is not used to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
