Description
Technical Field
[0001] This utility model belongs to the field of protective engineering technology, specifically a steel corrugated plate shed with a passive protective net. Background Technology
[0002] Steel corrugated plate tunnels primarily provide a robust shelter for roads, railways, and traffic safety below, and are widely used in slope protection structures along mountain highways and railways.
[0003] The steel-structured corrugated plate shed mainly consists of three parts: a steel frame, a corrugated plate roof, and a foundation and backfill. The steel frame is the skeleton of the entire structure, bearing all external loads and transferring them to the foundation. The corrugated plate roof directly withstands the impact of falling rocks. The foundation and backfill firmly anchor the entire structure to the ground and guide slope runoff to prevent erosion of the foundation, thereby ensuring a safe clearance area below.
[0004] Traditional steel corrugated plate shelter protection is quite bulky, requiring large hoisting equipment, making transportation and installation difficult. It relies on the strength of the material to withstand impacts, and is prone to plastic deformation when subjected to impacts. Repairs usually require cutting and replacement, making maintenance inconvenient.
[0005] Therefore, this utility model provides a steel corrugated plate shed with a passive protective net. Utility Model Content
[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

Through the above structure, the protective plate can reduce the structural weight, reduce the difficulty of transportation and hoisting, and the high-molecular polymer material can effectively resist aging, ensuring the service life of the product. Furthermore, the protective plate has good insulation properties, allowing it to adapt to various discharge environments. During installation, the protective plates can be quickly connected, and when damaged by external forces or unforeseen circumstances, they can be replaced individually, reducing material waste from overall replacement. In addition, the reserved expansion space during the use of the protective plate can accommodate the installation of multi-functional systems.
[0008] Preferably, the buffer assembly includes several elastic plates; the elastic plates are equidistantly distributed in the middle of the protective plate; the elastic plates are V-shaped; buffer layers are fixed to the ends of multiple elastic plates; and flexible pads are fixed to the middle of the buffer layers. Through the above structure, multi-level protection can reduce energy impacts exceeding the limits of the protective plate itself, reduce peak loads, effectively reduce fatigue damage to the protective plate during the protection of the opening, and improve the service life of the entire opening. The buffer layer and flexible pad directly bear the initial impact and friction, while the elastic plates disperse the deformation pressure, making the protective plate less prone to surface damage and cracks, and maintaining its integrity for long-term use.
[0009] Preferably, the flexible pad has a plurality of first grooves in the middle; the ends of the plurality of first grooves have second grooves; the flexible pad has two slots in the middle; the two slots are located at the ends of the second grooves; a locking block is installed in the middle of the two slots; a connecting pipe is fixedly connected to the end of the locking block; the above structure can effectively reduce the long-term water flow remaining on the surface of the buffer layer, reduce water flow seepage into the protective board, keep the surface of the board dry, and effectively reduce the increase of rainwater accumulation on the temporary load of the shed opening, reducing the additional load pressure of the shed opening.
[0010] Preferably, a connecting block is fixed to the side wall of the flexible pad; a second connecting groove is formed on the side wall of the flexible pad; the connecting block and the second connecting groove are toothed; the connection between the connecting block and the second connecting groove through the above structure makes it difficult for the flexible pads to be easily punctured from the joint, effectively suppressing the relative displacement between the buffer layers and maintaining the long-term stability of the structure.
[0011] Preferably, two fixing rods are fixedly connected to the middle of the buffer layer; two mounting grooves are opened in the middle of the protective plate; a pressure sensor is installed in the middle of the mounting groove; the pressure sensor is positioned corresponding to the fixing rod; the above structure can issue an early warning before the performance of the flexible pad deteriorates or the main structure is damaged, so that managers can plan and carry out maintenance in a timely manner, reducing sudden or emergency repair work.
[0012] Preferably, an elastic pad is fixed to the end of the fixing rod; the elastic pad is fixed to the end near the pressure sensor; the above structure can effectively reduce physical damage to the pressure sensor caused by hard contact between the fixing rod and the pressure sensor, maintain the calibration accuracy and performance of the pressure sensor, and extend its service life.
[0013] The beneficial effects of this utility model are as follows:

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0024] like Figures 1 to 5 As shown in the embodiment of this utility model, a steel corrugated plate shed with a passive protective net includes a protective plate 1; the protective plate 1 is arc-shaped; multiple cavities 10 are provided in the middle of the protective plate 1; multiple reinforcing ribs 11 are fixedly connected to the middle of the protective plate 1; a first connecting groove 12 is opened on the side wall of the protective plate 1; a connecting plate 13 is fixedly connected to the side wall of the protective plate 1; the first connecting groove 12 and the connecting plate 13 are opposite to each other; multiple sleeve connectors 14 are fixedly connected to the ends of the protective plate 1; a buffer assembly 2 is installed in the middle of the protective plate 1; during operation, the protective plate 1 is a high-molecular polymer as the raw material and basalt fiber as the skeleton material, which is a high-molecular polymer plate that is cured and formed under high temperature and high pressure. The curvature of the protective plate 1 can be customized according to the design. When two protective plates 1 are connected laterally, the connecting plate 13 enters the corresponding first connecting groove 12. The lateral connection is a reserved channel, and the lateral connection is made by prestressed steel strands. The sleeve connectors 14 are... The self-locking type sleeve connector 14 is inserted into the other end of the protective plate 1 during connection, and the circumferential connection is a variable arc sleeve connector 14, which is customized according to the tunnel arc. The circumferential structure is a structure in which the first connecting groove 12 and the connecting plate 13 cooperate, and the two protective plates 1 are quickly installed. The protective plates 1 are laterally reinforced by the reinforcing ribs 11. Multiple protective plates 1 protect the tunnel opening. Through the above structure, the protective plates 1 can reduce the structural weight and reduce the difficulty of transportation and hoisting. The high molecular polymer material can effectively resist aging and ensure the service life of the product. The protective plates 1 have good insulation, so they can adapt to the discharge environment. At the same time, the protective plates 1 can be quickly connected during installation. When external force or unforeseen damage occurs, they can be replaced individually, reducing the material waste caused by overall replacement. In addition, the reserved expansion space during the use of the protective plates 1 can accommodate the installation of multi-functional systems.
[0025] like Figure 4As shown, the buffer assembly 2 includes several elastic plates 21; the elastic plates 21 are equidistantly distributed in the middle of the protective plate 1; the elastic plates 21 are V-shaped; buffer layers 22 are fixed to the ends of the multiple elastic plates 21; a flexible pad 23 is fixed to the middle of the buffer layer 22; during operation, when falling rocks concentrate in the tunnel, they first impact the flexible pad 23 and the buffer layer 22, causing the buffer layer 22 and the flexible pad 23 to undergo compression deformation and absorb a large amount of kinetic energy during the impact dehumidification stage. The flexible pad 23 initially disperses the concentrated impact force over a larger area. When subjected to vertical downward pressure, the two inclined surfaces of the multiple elastic plates 21 are forced to bend, storing a portion of the impact force during the deformation of the elastic plates 21. The energy is dissipated through two stages of efficient dissipation, and the impact on the final protective plate 1 becomes very small and uniform. Thus, the protective plate 1 bears part of the load, increasing the protection of the opening. Through the above structure and multi-stage protection, the energy impact exceeding the limit of the protective plate 1 itself can be reduced, the peak load is reduced, the fatigue damage of the protective plate 1 to the opening is effectively reduced, and the service life of the entire opening is improved. The buffer layer 22 and the flexible pad 23 directly bear the initial impact and friction, and the elastic plate 21 disperses the deformation pressure, which makes the protective plate 1 less prone to surface damage and cracks, maintaining the integrity of long-term use.
[0026] like Figure 5 As shown, the flexible pad 23 has multiple first grooves 3 in the middle; the ends of the multiple first grooves 3 have second grooves 31; the flexible pad 23 has two slots 32 in the middle; the two slots 32 are located at the ends of the second grooves 31; a locking block 33 is installed in the middle of the two slots 32; a connecting pipe 34 is fixedly connected to the end of the locking block 33; during operation, after the protective plate 1 is installed, the connecting pipe 34 is installed in the protective plates 1 on both sides, and the two locking blocks 33 are placed inside the slots 32 respectively, and the locking blocks 33 are locked by the slots 32, thus securing the connecting pipe 34. 4. Fixing: During the process of the protective plate 1 protecting the shed opening, when rainwater enters the surface of the flexible pad 23, some of the water flows along the first groove 3 and enters the second groove 31 through the first groove 3, connecting the main drainage pipe to the connecting pipe 34, and then draining into the main drainage system through the connecting pipe 34. The above structure can effectively reduce the long-term water flow remaining on the surface of the buffer layer 22, reduce water flow seepage into the protective plate 1, keep the surface of the plate dry, and effectively reduce the increase of rainwater accumulation on the temporary load of the shed opening, thus reducing the additional load pressure on the shed opening.
[0027] like Figure 1 and Figure 4As shown, a connecting block 4 is fixed to the side wall of the flexible pad 23; a second connecting groove 41 is opened on the side wall of the flexible pad 23; the connecting block 4 and the second connecting groove 41 are toothed; during operation, when the two protective plates 1 are connected, the connecting block 4 enters the middle of the corresponding second connecting groove 41, and the connecting block 4 and the second connecting groove 41 fit tightly together, so that they interlock with each other. Through the above-mentioned structure, the connecting block 4 and the second connecting groove 41 can make it difficult for the flexible pad 23 to be easily penetrated from the joint, which can effectively suppress the relative displacement between the buffer layers 22 and maintain the long-term stability of the structure.
[0028] like Figure 4 As shown, two fixing rods 5 are fixed in the middle of the buffer layer 22; two mounting grooves 52 are opened in the middle of the protective plate 1; a pressure sensor 51 is installed in the middle of the mounting groove 52; the pressure sensor 51 is positioned corresponding to the fixing rods 5; during operation, due to long-term weathering, temperature difference deformation and continuous impact from small falling rocks, the flexible pad 23 will gradually become thinner. As the flexible pad 23 becomes thinner, the fixing rods 5 will move downward synchronously, and the gap between the fixing rods 5 and the pressure sensor 51 will gradually decrease until it becomes zero, and gradually increasing pressure will be applied to the sensor. After being subjected to pressure, the system will be alerted. Through the above structure, an early warning can be issued before the performance of the flexible pad 23 deteriorates or the main structure is damaged, so that managers can plan and perform maintenance in a timely manner, reducing sudden or emergency repair work.
[0029] like Figure 4 As shown, an elastic pad 6 is fixed to the end of the fixing rod 5; the elastic pad 6 is fixed to one end near the pressure sensor 51; during operation, through the flexible material of the elastic pad 6, when the force at the end of the fixing rod 5 is applied to the pressure sensor 51, the fixing rod 5 and the pressure sensor 51 make flexible contact. Through the above structure, the physical damage to the pressure sensor 51 caused by hard contact between the fixing rod 5 and the pressure sensor 51 can be effectively reduced, the calibration accuracy and performance of the pressure sensor 51 can be maintained, and its service life can be extended.
[0030] like Figure 3 As shown, the cavity 10 is filled with high-density foam material. When it is impacted during operation, the impact energy is transferred to the foam core material through the buffer component 2. The core material absorbs and dissipates the impact energy in large quantities through its controllable compression and deformation. The high-density foam material can effectively increase the mechanical properties of the protective plate 1 and reduce the energy transferred to the back side, thereby protecting the structure and space of the back side.
[0031] During operation, the protective plate 1 is made of high-molecular polymer as the raw material and basalt fiber as the skeleton material. It is a high-molecular polymer plate cured under high temperature and pressure. The curvature of the protective plate 1 can be customized according to the design. When two protective plates 1 are connected laterally, the connecting plate 13 enters the corresponding first connecting groove 12. The lateral connection uses a pre-reserved channel and is achieved through prestressed steel strands. The sleeve connector 14 is self-locking; during connection, the sleeve connector 14 is inserted into the other end of the protective plate 1. The circumferential connection uses a variable curvature sleeve connector 14, customized according to the tunnel curvature. The circumferential structure is a mating structure between the first connecting groove 12 and the connecting plate 13, allowing for quick and easy installation of the two protective plates 1. The protective plate 1 is laterally reinforced by reinforcing ribs 11. Multiple protective plates 1 protect the opening. When falling rocks concentrate in the opening, they first impact the flexible pad 23 and the buffer layer 22. The buffer layer 22 and the flexible pad 23 undergo compression deformation and absorb a large amount of kinetic energy during the impact dehumidification stage. The flexible pad 23 initially disperses the concentrated impact force over a larger area. When subjected to vertical downward pressure, the two inclined surfaces of several elastic plates 21 are forced to bend. When the elastic plates 21 deform, they store some energy and attempt to rebound after the impact, consuming some of the impact energy. After two stages of efficient dissipation, the impact on the final protective plate 1 becomes very small and uniform, thus the protective plate 1 withstands the impact. Partially contributing to the load-bearing capacity, this increases the protection of the shed opening. After the protective plate 1 is installed, the connecting pipe 34 is installed in the protective plates 1 on both sides. Two locking blocks 33 are placed inside the corresponding slots 32, and the locking blocks 33 are locked in place by the slots 32, thus fixing the connecting pipe 34. During the process of the protective plate 1 protecting the shed opening, when rainwater enters the surface of the flexible pad 23, some of the water flows along the first groove 3, passes through the first groove 3 and enters the second groove 31, connecting the main drainage pipe to the connecting pipe 34, and draining into the main drainage system through the connecting pipe 34. When the two protective plates 1 are connected, the connecting block 4 enters the middle of the corresponding second connecting groove 41, and the connecting block 4 and the second connecting groove 41 fit tightly together, making them mutually... Due to long-term weathering, temperature difference deformation, and continuous impact from small falling rocks, the flexible pad 23 will gradually become thinner. As the flexible pad 23 becomes thinner, the fixing rod 5 will move downward synchronously. The gap between the fixing rod 5 and the pressure sensor 51 will gradually decrease until it becomes small, and gradually increasing pressure will be applied to the sensor. When pressure is applied, the background system will be alerted. Through the flexible material of the elastic pad 6, when the force at the end of the fixing rod 5 acts on the pressure sensor 51, the fixing rod 5 and the pressure sensor 51 will make flexible contact. When impacted, the impact energy is transferred to the internal foam core material through the buffer component 2. The core material absorbs and dissipates a large amount of impact energy through its controllable compression and deformation.
