Description

Technical Field

[0002] With the acceleration of the urbanization process, more and more cities have started to build subways, and the construction of rail transit has ushered in rapid development, making the construction of rail transit passing under roads more and more frequent, posing certain risks and pressures to the operation safety and unobstructed work of roads, especially high-grade roads.

[0003] With the development of shield construction and monitoring technologies, the requirements for intelligence are increasing day by day on the premise of ensuring safety and efficiency. For roads, especially high-grade roads, there are many passing vehicles and high speeds every day, and strict requirements are imposed on the displacement of the roadbed or bridge during the construction of the shield tunnel passing under the road to ensure operation safety. At present, most road-related construction projects conduct manual monitoring and data collection at a certain frequency and report the data to the road department regularly; as a result, the monitoring data is not used in a timely manner to guide the construction of the shield tunnel passing under the road, and at the same time, the road department does not learn about the progress of the road-related project and the construction risk situation on site in a timely manner; the timeliness and convenience of taking preventive and emergency measures through multi-party linkage before and during the occurrence of emergencies are reduced.

[0004] During the construction of a shield tunnel passing under a road, it is usually necessary to set up a monitoring control box to monitor and control the construction process in real time. However, the existing monitoring control boxes have the following technical problems:

[0007] Difficult to maintain: The internal structure is complex, and it is inconvenient to clean and maintain, and it is easy to accumulate dust and impurities.

[0008] Poor adaptability: Lack of flexibility and difficult to meet the requirements of different construction environments.

[0009] Noise problem: The noise generated by the operation of the cooling fan affects the surrounding environment.

[0010] Improper condensation water treatment: Condensation water is likely to be generated in an environment with a large temperature difference, which may damage the internal equipment. Content of the Utility Model

Detailed implementation manners

[0037] The following further elaborates on the utility model of the present application in detail with reference to the attached drawings and specific embodiments. For a clear and complete description of the technical solution, the following embodiments are selected for illustration; based on the content recorded in the present application, other embodiments obtained without creative labor fall within the protection scope of the present utility model.

[0038] In the following embodiments, it should be noted that the orientation or positional relationships such as "upper", "lower", "left", "right", "inner", "outer", "top / bottom", etc. in the terms are all based on the orientation or positional relationships shown in the drawings. This is only for the convenience of clearly describing this embodiment, rather than indicating or implying that the device or component referred to must have a specific orientation. Therefore, it should not be construed as a limitation to this application.

[0039] There are multiple technical problems in the existing monitoring control box for shield tunnel underpassing a road during road-crossing construction. The primary problem is how to improve the dust and moisture protection performance of the monitoring control box to adapt to the harsh construction environment and protect the internal precision instruments. Secondly, considering that the filter screen needs to be cleaned and replaced regularly, the present invention focuses on solving the problem of how to achieve easy disassembly and replacement of the filter screen to improve the maintenance efficiency. In addition, the traditional filter screen frame often generates vibration noise during operation, affecting the surrounding environment.

[0040] To solve the above problems, the specific embodiments of the present utility model are as follows:

[0041] As Figures 1 - 10 shown, a monitoring control box for shield tunnel underpassing a road during road-crossing construction includes a box body 1. A box door 2 is hinged to the front of the box body 1. A monitoring host 3 is installed inside the box body 1. The monitoring host 3 is built-in with a monitoring data real-time sharing platform, a shield intelligent computing system center, and a road data center, and the monitoring host 3 is signal-connected to the settlement monitoring points and horizontal displacement monitoring points.

[0042] For a specific test section: In the test section, the settlement monitoring points are arranged on the ground surface, directly above the tunnel, and on both sides of the tunnel. This is a monitoring section of the test section, and a section is arranged at a certain distance interval.

[0043] When the shield tunnel passes under a road with a roadbed form, settlement monitoring points are set on the road shoulder and the toe of the roadbed slope, directly above the tunnel, and on both sides of the tunnel.

[0044] When the shield tunnel passes under a road with a bridge form, settlement monitoring points and horizontal displacement monitoring points are set at the bottom of the bridge pier.

[0045] The strata of the test section are similar to those of the section where the shield tunnel passes under the road. By collecting, searching, etc. data such as the tunneling parameters of the shield machine, the horizontal displacement and settlement of the road in the test section, machine learning can provide technical references such as shield tunneling parameters for subsequent road-crossing construction.

[0046] The monitoring data real-time sharing platform can receive the settlement and horizontal displacement monitoring data, display them graphically, and share the data in real time with the shield intelligent computing center and the road data center.

[0047] The shield intelligent computing center can receive the data of the real-time sharing platform of monitoring data in real time, perform machine learning, and adjust the shield tunneling parameters according to the magnitude of settlement or horizontal displacement in the monitoring data.

[0048] The highway data center can receive the data of the real-time sharing platform of monitoring data in real time, learn about the dynamics of road-related projects, the displacement and deformation of the highway in real time, and maintain a real-time linkage mechanism with the shield construction.

[0049] It also includes:

[0050] The air inlet component 4 is installed on the box door 2, and a dust and moisture-proof mechanism 5 is arranged on the air inlet component 4;

[0051] The exhaust component 6 is installed on the top of the box body 1 for dissipating heat from the box body 1, and a cleaning mechanism 7 is arranged on the exhaust component 6;

[0052] The air inlet component 4 includes an opening 8 formed in a rectangular shape on the box door 2, and the dust and moisture-proof mechanism 5 is installed at the position of the box door 2 where the opening 8 is located;

[0053] The dust and moisture-proof mechanism 5 includes a first filter screen 9 fixedly connected to the box door 2 by rivets. The first filter screen 9 is embedded in the opening 8. A box-type filter screen 10 is fixedly connected to the outer side of the box door 2 by rivets. Slideways 11 arranged in a U shape are formed on both sides of the inner wall of the box-type filter screen 10. A detachable rectangular frame 12 is slidably connected to the slideways 11. A multi-layer filter screen 13 is arranged inside the rectangular frame 12. The multi-layer filter screen 13 includes, but is not limited to, a sponge layer, a HEPA filter layer, and a PTFE waterproof and breathable layer.

[0054] A plurality of openings are formed in the inner bottom of the slideway 11. A slide bar 14 is slidably connected to the plurality of openings. A first wedge-shaped surface 15 is arranged at the bottom end of the slide bar 14. A slide bar 16 is also slidably arranged at the bottom of the slideway 11. A first inclined surface 17 and a second inclined surface 18 are respectively arranged on the slide bar 16. The first inclined surface 17 is in sliding contact with the first wedge-shaped surface 15. Pressure bars 19 are vertically arranged on both sides of the slideway 11. A second wedge-shaped surface 20 is arranged at the bottom end of the pressure bar 19. The second wedge-shaped surface 20 is in sliding contact with the second inclined surface 18. A rubber strip is arranged on the side of the pressure bar 19 close to the rectangular frame 12 for pressing the rectangular frame 12 to reduce the vibration noise of the rectangular frame 12.

[0055] First, the air intake component 4 is arranged on the cabinet door 2, and external air is introduced through the opening 8. The air first undergoes primary filtration through the box-shaped filter screen 10 fixed on the outer side of the cabinet door 2, and then undergoes secondary filtration through the first filter screen 9 embedded in the opening 8. The core filtration is completed by the multi-layer filter screen 13 within the detachable rectangular frame 12 to achieve deep filtration. The design of the U-shaped slideway 11 allows the rectangular frame 12 to be slidably installed and disassembled, facilitating maintenance. The wedge-shaped structure composed of the slide bar 14, the slide strip 16, and the pressure strip 19 realizes the stable installation of the frame through mutual abutment. The rubber strip on the pressure strip 19 presses the rectangular frame 12, effectively reducing vibration noise.

[0056] A plurality of openings are formed in the inner bottom of the slideway 11, and the slide bar 14 is slidably connected within the openings. The first wedge-shaped surface 15 at the bottom end of the slide bar 14 slidably abuts against the first inclined surface 17 on the slide strip 16. At the same time, the second inclined surface 18 on the slide strip 16 slidably abuts against the second wedge-shaped surface 20 at the bottom end of the pressure strip 19. The multiple wedge-shaped structures enable the rectangular frame 12 to automatically adjust its position during installation, ensuring a good sealing effect. The rubber strip on the side of the pressure strip 19 close to the rectangular frame 12 not only plays a pressing role but also further enhances the sealing effect, while effectively reducing the vibration noise of the frame. The design of the plurality of slide bars 14 and slide strips 16 allows the pressure to be adjusted according to actual needs, enabling the present invention to adapt to filter screens of different thicknesses.

[0057] The use of the multi-layer filter screen 13 significantly improves the dust and moisture protection effects and effectively protects the internal equipment of the control box. Secondly, the design of the detachable rectangular frame 12 greatly improves the maintainability of the filter screen, facilitating regular cleaning and replacement, and extending the service life of the equipment.

[0058] The exhaust component 6 includes a fixed housing 21 installed on the top of the box body 1. The fixed housing 21 is communicated with the inner cavity of the box body 1. An air-permeable motor support shell 22 is installed on the fixed housing 21. A driving motor 23 is fixedly installed on the motor support shell 22. A fan blade is installed on the output end of the driving motor 23. Dust-proof nets 24 are fixedly installed on both sides of the motor support shell 22. Ventilation openings 25 in the shape of louvers are formed on the side plates of the fixed housing 21.

[0059] The inner side of the top plate of the fixed housing 21 is arranged in an arc-shaped cone. A guiding plate 26 is fixedly connected to the inner wall of the side plate of the fixed housing 21. The guiding plate 26 penetrates through the side plate of the fixed housing 21, and the inner end of the guiding plate 26 is located below the tip of the arc-shaped cone for receiving water and guiding the condensed water to drain out through the guiding plate 26.

[0060] The cleaning mechanism 7 includes a limit sliding groove 27 opened on the fixed housing 21. A T-shaped rod 28 is slidably connected in the limit sliding groove 27. The T-shaped rod 28 includes a cross bar 29 and a longitudinal bar 30. The cross bar 29 is slidably arranged in the limit sliding groove 27, and the longitudinal bar 30 extends to the outside of the fixed housing 21. A scraping plate 31 is arranged on the lower side of the cross bar 29. The lower side of the scraping plate 31 contacts the dust-proof net 24 and is used to scrape off impurities on the dust-proof net 24.

[0061] Among them, the fixed housing 21 is directly communicated with the inner cavity of the box body 1, ensuring the rapid discharge of hot air. The hollow motor support shell 22 not only supports the driving motor 23 but also minimizes the air flow resistance to the greatest extent. The driving motor 23 drives the fan blades to rotate at a high speed, generating a strong air extraction effect. Thus, the heat inside the box body 1 can be quickly discharged, effectively reducing the internal temperature and creating an ideal working environment for the monitoring host 3.

[0062] The dust-proof nets 24 on both sides of the motor support shell 22 filter out dust in the air and prevent it from entering the box body 1. The louver-shaped ventilation openings 25 further block large dust particles.

[0063] The arc-shaped conical design on the inner side of the top plate of the fixed housing 21 enables the condensed water to naturally gather at the center. The guiding plate 26 is located below the conical tip, collecting and guiding the condensed water to drain out of the box body 1. This not only prevents water droplets from falling onto the internal equipment but also avoids equipment damage caused by excessive humidity, greatly improving the adaptability of the monitoring control box in an environment with large temperature differences.

[0064] The T-shaped rod 28 in the cleaning mechanism 7 can slide in the limit sliding groove 27. When operating the longitudinal bar 30, the cross bar 29 drives the scraping plate 31 to move on the surface of the dust-proof net 24, scraping off the accumulated dust and impurities, greatly reducing the frequency and difficulty of manual cleaning, reducing the maintenance cost, and improving the long-term operation efficiency of the equipment.

[0065] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any minor modifications, equivalent replacements, and improvements made to the above embodiments based on the technical essence of the present invention shall be included within the protection scope of the technical solution of the present invention.
