[0002] Small-radius shield tunneling refers to areas in urban subways, highway tunnels, or other underground projects where the turning radius is relatively small due to geographical conditions or design requirements. Shield boring is a tunneling technique that uses a shield machine to excavate the tunnel underground. In small-radius tunnel construction, the shield machine must maintain high precision and stability during turns to ensure the tunnel's structural safety and functionality.

[0003] An emergency shelter is a structure that provides temporary shelter for people in emergency situations. It is typically located in places where emergencies may occur, such as underground tunnels, subway platforms, and inside large buildings. Its purpose is to provide a safe, temporary refuge for people in the event of disasters such as fires, earthquakes, and terrorist attacks until rescuers arrive.

[0004] In the process of realizing the present utility model, the inventors discovered that the existing technology had the following problems: 1. The existing emergency shelter platform lacks lighting and ventilation systems to address the problems of low visibility and poor ventilation in the regional space; 2. Small-radius shield tunnels generally use short pipe segments, and standardized emergency rescue platforms are not suitable and need to be customized to meet the usage requirements. In addition, the existing emergency shelter platform is difficult to contact the outside world in a timely manner. Utility Model Content

[0005] The purpose of the present utility model is to provide a customized emergency shelter platform for use in small-radius shield tunnel sections, so as to solve the problems raised in the above-mentioned background technology that the existing emergency shelter platforms lack lighting systems and ventilation systems to cope with the low visibility and poor ventilation in the regional space, and that the small-radius shield tunnel sections generally use short pipe segments, to which standardized emergency rescue platforms are not suitable and need to be customized to meet the use requirements, and the existing emergency shelter platforms are also difficult to contact the outside world in a timely manner. In order to achieve the above-mentioned purpose, the present utility model provides the following technical solutions: a customized emergency shelter platform for use in small-radius shield tunnel sections, comprising a thin steel plate, L-steel plates welded to opposite sides of the thin steel plate, a wire mesh provided on the inner wall of the L-steel plate, a ventilation hood threadedly connected to the left and right sides of the bottom of the L-steel plate, a fan clamped inside the ventilation hood, a communication mechanism provided on the inner wall of the thin steel plate close to the ventilation hood, and a bolt hole provided on the other end of the thin steel plate.

[0006] Further preferably, guardrails are provided on the left and right sides of the top of the L-shaped steel plate.

[0007] Further preferably, the outer wall of the steel mesh is coated with an anti-slip and wear-resistant layer.

[0008] Further preferably, a plurality of emergency lighting lamps are provided on the front and rear sides of the bottom of the L-shaped steel plate.

[0009] Further preferably, mounting screw plates are provided on the left and right sides of the top of the ventilation hood, and a breathable partition is provided at the front opening of the ventilation hood, and the ventilation hood and the fan together constitute a ventilation mechanism.

[0010] Further preferably, the thin steel plate is customized according to the width of the pipe segment and the curvature of the small-radius tunnel and is arranged in a curved shape.

[0011] Further preferably, the communication mechanism consists of a display screen, a button, a speaker, a communicator and a control panel, wherein the display screen is arranged on the outside of the control panel, the button is arranged on the control panel directly below the display screen, the speaker is arranged on the control panel on one side below the button, and the communicator is arranged on the control panel on the other side below the button.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In the utility model, the guardrail provides additional protection for the operator, reducing the risk of falling or accidental slipping. The outer wall of the wire mesh is coated with an anti-slip and wear-resistant layer, which provides an additional anti-slip surface, effectively reducing the risk of injury accidents caused by slipping. The emergency lighting can significantly improve the visibility of the local area, help the operator quickly locate the emergency shelter platform, and speed up the shelter response speed. At the same time, the emergency lighting can also help rescuers quickly find and rescue trapped people in an emergency. The ventilation mechanism can effectively bring fresh air into the platform and discharge the polluted air, thereby improving the air quality of the area. In the event of disasters such as fire and landslide, the ventilation mechanism can quickly reduce the concentration of harmful gases, which helps to protect the health and safety of the operators.

[0014] In the present invention, by precisely measuring and customizing thin steel plates and L-steel plates and other components, it is possible to ensure that the emergency rescue platform is highly matched with the size and shape of the tunnel, thereby providing stable support and fitting effects. The design of the curved thin steel plate enables the platform to fit the curvature of the tunnel, which helps to provide operators with a stable working surface in an emergency and reduce the risk of slipping or falling due to an unstable platform. Moreover, because the curvature of a small-radius tunnel is large, the customized curved thin steel plate can ensure the adaptability of the platform in the tunnel and avoid structural damage during installation or use. At the same time, the segment bolts pass through the bolt holes opened on the end face of the thin steel plate and are screwed to the inner wall of the tunnel. This design simplifies the installation process and facilitates subsequent maintenance and inspection. Through the communication mechanism, the operator can immediately contact external rescue personnel or the command center to quickly convey emergency and location information.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technical personnel in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0022] See also Figures 1 to 5 The utility model provides a technical solution: a customized emergency shelter platform for a small semi-long shield section, comprising a thin steel plate 1, L steel plates 2 welded on opposite sides of the thin steel plate 1, a steel mesh 3 provided on the inner wall of the L steel plate 2, a ventilation hood 4 threadedly connected to the left and right sides of the bottom of the L steel plate 2, a fan 5 clamped inside the ventilation hood 4, a communication mechanism 6 is provided on the side of the inner wall of the thin steel plate 1 close to the ventilation hood 4, and a bolt hole 7 is opened at the other end of the thin steel plate 1.

[0023] In this embodiment, Figure 1 and Figure 2As shown, guardrails 201 are provided on the left and right sides of the top of the L-steel plate 2; it should be noted that in the present invention, guardrails 201 are provided on the left and right sides of the top of the L-steel plate 2, and the guardrails 201 and the extended part of the thin steel plate 1 together surround the entire wire mesh 3 to play a protective role. In actual use, the guardrails 201 provide additional protection for operators, reducing the risk of falling or accidentally slipping when working on the platform. By working together with the extended part of the thin steel plate 1, the guardrails 201 also form a closed boundary to ensure that people and tools on the platform will not slip from the edge, and the clear boundaries of the guardrails 201 help to distinguish between working areas and non-working areas, reminding personnel to pay attention to safety and comply with operating procedures. At the same time, in an emergency, the guardrails 201 can be used as a reference point for quickly identifying and reaching the edge of the platform, facilitating rapid evacuation and rescue.

[0024] In this embodiment, Figure 3 As shown, the outer wall of the wire mesh 3 is coated with an anti-skid and wear-resistant layer 301; it should be noted that when the operator performs various platform operations on the top of the wire mesh 3, the operator will move on the top of the wire mesh 3, and in emergency avoidance, the operator may be in danger of slipping on the wire mesh 3 due to tension. Therefore, in the utility model, the outer wall of the wire mesh 3 is coated with an anti-skid and wear-resistant layer 301, so that in actual use, the anti-skid and wear-resistant layer 301 provides an additional anti-skid surface, reducing the risk of operators slipping when walking or standing on the surface of the wire mesh 3, effectively reducing the risk of injury accidents caused by slipping, and in emergency avoidance, the anti-skid and wear-resistant layer 301 can provide a more stable surface, thereby increasing the safety and stability of the operator's avoidance, and at the same time, the anti-skid and wear-resistant layer 301 can also protect the wire mesh 3 from wear and tear, thereby extending the service life of the platform in harsh shield sections.

[0025] In this embodiment, Figure 3 As shown, several emergency lights 202 are provided on the front and back sides of the bottom of the L steel plate 2; it should be noted that, usually in the shield section, because there is no sunlight, the visibility of the internal environment is low, and in an emergency, the operator needs to spend more time and energy to find the emergency escape platform, which easily leads to untimely escape and increases the accident rate. Therefore, in the present utility model, several emergency lights 202 are provided on the front and back sides of the bottom of the L steel plate 2. In actual use, in the shield section without natural light, by turning on the emergency lights 202, the visibility of the local area can be significantly improved, helping the operator to quickly locate the emergency escape platform, thereby speeding up the escape response speed. In an emergency, the emergency lights 202 can also serve as an escape route indicator to guide the operator to evacuate to a safe area quickly and orderly. At the same time, the lighting of the emergency lights 202 also helps rescue personnel to quickly find and rescue trapped people in an emergency.

[0026] In this embodiment, Figure 4 As shown, screw plates 401 are provided on the left and right sides of the top of the ventilation hood 4, and a breathable partition 402 is provided at the front opening of the ventilation hood 4. The ventilation hood 4 and the fan 5 together constitute a ventilation mechanism. It should be noted that during daily operations, operators may encounter disasters such as fire, landslides, and floods, and these disasters will not only damage the structure of the entire shield section, but also affect the air circulation inside the section. Therefore, in the present invention, the ventilation hood 4 is screwed to the left and right sides of the bottom of the L steel plate 2 by installing screw plates 401, and the inside of the ventilation hood 4 is also clamped with a fan 5. By opening the fan Fan 5, with its blades driving the surrounding air to flow, blows the gas to the internal space of the platform through the breathable partition 402 to enhance air circulation. In actual use, through the operation of fan 5, fresh air can be effectively brought into the interior of the platform, while the polluted air is discharged, thereby improving the air quality of the area. In addition, when disasters such as fire and landslide occur, the ventilation mechanism can quickly reduce the concentration of harmful gases, which helps to protect the health and safety of the operators. At the same time, in a high temperature environment, the good ventilation provided by the ventilation mechanism can also reduce the heat stress of the operators and improve work efficiency and comfort.

[0027] In this embodiment, Figure 1 and Figure 3 As shown, the thin steel plate 1 is customized according to the width of the segment and the curvature of the small-radius tunnel and is set in a curved shape; it should be noted that the small-radius shield tunnel generally uses short segments and requires a customized emergency rescue platform. Therefore, in the present invention, according to the width of the tunnel segment and the curvature of the small-radius tunnel, the thin steel plate 1 and the L steel plate 2 and other components are finely measured and customized, and the thin steel plate 1 is set to a curved plate body equal to the curvature of the tunnel radius, and the segment bolts pass through the bolt holes 7 opened on the end face of the thin steel plate 1 to fit the inner wall of the tunnel. In actual use, by finely measuring and customizing the thin steel plate 1 and the L steel plate 2 and other components, emergency rescue can be ensured. The platform is highly matched to the size and shape of the tunnel, providing stable support and fit. The design of the curved thin steel plate 1 enables the platform to fit the curvature of the tunnel, which helps to provide operators with a stable working surface in an emergency and reduce the risk of slipping or falling due to an unstable platform. Moreover, because the curvature of a small-radius tunnel is large, the customized curved thin steel plate 1 can ensure the adaptability of the platform in the tunnel and avoid structural damage during installation or use. At the same time, the segment bolts pass through the bolt holes 7 opened on the end face of the thin steel plate 1 and are screwed to the inner wall of the tunnel. This design simplifies the installation process and facilitates subsequent maintenance and inspection.

[0028] In this embodiment, Figure 1 and Figure 5As shown, the communication mechanism 6 is composed of a display screen 601, a button 602, a speaker 603, a communicator 604 and a control panel 605, wherein the display screen 601 is arranged on the outside of the control panel 605, the button 602 is arranged on the control panel 605 directly below the display screen 601, the speaker 603 is arranged on the control panel 605 on one side below the button 602, and the communicator 604 is arranged on the control panel 605 on the other side below the button 602; it should be noted that when the operator is taking emergency shelter, the surrounding environment is chaotic and dangerous, so it is necessary to provide the operator with a communication device that can communicate with the outside world, so in the utility model, a communication mechanism 6 is provided on the inner wall of the thin steel plate 1 near the ventilation hood 4. After manually pressing the corresponding button 602, the operator can contact outside personnel through the communicator 604 and the speaker 603 and wait for rescue. In actual use, through the communicator 604 in the communication mechanism 6, the operator can immediately contact the outside rescue personnel or the command center to quickly convey the emergency and location information, and the speaker 603 can amplify the operator's voice to ensure that the rescue personnel can clearly hear the distress message in a noisy or chaotic environment. The button 602 is designed to be manually operated, and the operator can quickly and easily start the communication mechanism 6 even in an emergency without complicated operations. At the same time, the display screen 601 can show the operator important information such as the status of communication with the outside world and the progress of the rescue.

[0029] The use method and advantages of this utility model: This utility model is used to customize an emergency escape platform in a small semi-circular shield tunnel section. When in use, the working process is as follows:

[0030] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, first, the operator can assemble together the various components such as the customized steel plate 1 and the L steel plate 2 according to the width of the tunnel segment and the curvature of the small radius tunnel, and pass the bolts of the segment through the bolt holes 7 opened on the end surface of the steel plate 1 to screw the curved steel plate 1 to the inner wall of the tunnel. In actual use, when encountering an emergency, the guardrail 201 can provide additional protection for the operator when he moves quickly, reducing the risk of falling or accidentally slipping, and the anti-skid and wear-resistant layer 301 coated on the outer wall of the wire mesh 3 can provide a more stable surface, increasing the safety and stability of the operator's avoidance of risks. At the same time, the emergency lighting 20 2 can significantly improve the visibility of the local area, help the operator quickly locate the emergency shelter platform, and guide the operator to hide inside the emergency shelter platform in time. During this period, the operator can manually press the corresponding button 602, and then contact the outside people through the communicator 604 and the speaker 603, and send a distress message. Then, while waiting for rescue, the operator can turn on the fan 5, so that the fan blades drive the surrounding air to flow, and bring fresh air into the platform through the breathable partition 402, while discharging the polluted air, thereby improving the air quality of the area and quickly reducing the concentration of harmful gases inside the platform to protect the health and safety of the operator.
