[0002] In inclined shaft engineering, the starting stage of TBM (full-face rock tunnel boring machine) equipment is a very challenging technical link. Due to the special geological conditions of the inclined shaft, the starting section is often accompanied by a large inclination angle, which makes the stability of the foundation device a prominent issue. Especially on the foundation concrete surface of the starting section, due to the influence of the inclination angle, it is difficult for the foundation device to obtain sufficient support force, so it is very easy to overturn or collapse.

[0024] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present application.

[0025] In inclined shaft engineering, the initial stage of TBM (tunnel boring machine) is undoubtedly the most critical and complex part of the entire engineering process. Especially in the initial stage of the inclined shaft, due to the large inclination angle of the ground, the stability of the foundation device is particularly critical. This stage not only tests the sophistication of engineering technology, but also poses a severe challenge to equipment safety.

[0026] If the foundation is placed on a sloping concrete surface, its stability will be seriously affected. Due to the effect of gravity, the device may overturn or even collapse, and this risk cannot be ignored. Once the foundation is unstable, the flatness and stability of the track will not be guaranteed, which will not only cause the TBM equipment to derail easily during travel, but also have a serious impact on the overall performance and service life of the equipment.

[0027] What is more serious is that the instability of the foundation may also trigger a series of chain reactions, leading to engineering accidents. Once such an accident occurs, it will not only cause serious damage to the equipment, but may also endanger the personal safety of on-site workers and bring immeasurable losses.

[0028] Therefore, in the initial stage of TBM in inclined shaft, ensuring the stability of the foundation device is of utmost importance. Only by taking effective measures, such as using special fixing devices and strengthening the support of the foundation structure, can the foundation device be ensured to remain stable on the inclined concrete surface, providing a solid guarantee for the smooth start of TBM equipment.

[0029] like Figure 1 As shown, the present application provides a starting foundation device for inclined shaft TBM, the design of which fully considers the particularity of the starting section of the inclined shaft and the stability requirements of the foundation device. Specifically, the device adopts high-strength materials and advanced structural design to ensure that it can be stably installed at a high inclination angle of the inclined shaft. In addition, the device is also equipped with a professional fixing and supporting system, so that it can remain stable in a complex engineering environment and effectively prevent risks such as overturning and collapse. The device includes:

[0030] The embedded plate 3 is fixedly connected to the inclined shaft foundation structure, and both ends of the embedded plate 3 are fixedly connected with arc plates 7, the side of the arc plate 7 away from the embedded plate 3 is fixedly connected to the sleeper leg 11, the end of the sleeper leg 11 away from the arc plate 7 is fixedly connected to the sleeper 2, and the end of the sleeper 2 away from the sleeper leg 11 is fixedly connected to the track 1.

[0031] The core component of the device includes an embedded plate 3 fixedly connected to the inclined shaft foundation structure. The embedded plate 3 is the foundation of the entire device, and its stability and fixity directly affect the performance of the entire device. In order to ensure the stability of the embedded plate 3, the present application designs an arc plate 7 with both ends fixedly connected. The design of the arc plate 7 takes into account both the stability of the connection with the embedded plate 3 and the connection with subsequent components.

[0032] On the side of the curved plate 7 away from the embedded plate 3, the present application designs a sleeper leg 11. One end of the sleeper leg 11 is fixedly connected to the curved plate 7, and the other end is fixedly connected to the sleeper 2. As a key component supporting the track, the stability and load-bearing capacity of the sleeper 2 are of great importance. Through the connection of the sleeper leg 11, the sleeper 2 can be firmly installed on the curved plate 7, thereby ensuring the flatness and stability of the track 1.

[0033] In some embodiments, the embedded plate 3 is fixedly connected to the curved plate 7 through the reinforcing ribs 8. When the embedded plate 3 is fixedly connected to the curved plate 7 through the reinforcing ribs 8, this structural combination can bring out their respective advantages. The reinforcing ribs 8 enhance the strength and stability of the embedded plate 3, making it more stable when subjected to external forces. The curved plate 7 further enhances the connectivity and protection of the structure, especially when it comes to the fixing and support of structural parts such as steel pipes, the role of the curved plate 7 is particularly significant.

[0034] In addition, in order to further enhance the stability of the entire device, the present application also designs symmetrically arranged sleeper oblique legs 4. One end of the sleeper oblique legs 4 is fixedly connected to the sleeper 2, and the other end is fixedly installed at the connection between the arc plate 7 and the embedded plate 3. The presence of the sleeper oblique legs 4 not only increases the support points of the device, but also improves the anti-overturning ability of the entire device.

[0035] In terms of connection methods, the present application adopts a combination of welding and bolting. For example, the sleeper inclined leg 4 is welded to the sleeper 2 to ensure the firmness of the connection; and the track pressure plate 5 is fixed to the sleeper 2 with connecting bolts 9 to facilitate installation and disassembly.

[0036] like Figure 2As shown, in the present application, the design of the track platen 5 takes into account the close connection with the sleeper 2, and is fixed to the sleeper 2 through the preset reserved holes 12. This design not only ensures the stable connection between the track platen 5 and the sleeper 12, but also makes the installation process simpler and more efficient. The connecting bolts 9 play a key fixing role. By passing the connecting bolts 9 through the track platen 5 and fixing them in the reserved holes 12 of the sleeper 2, the track 1 is firmly mounted on the track platen 5. This fixing method is not only firm and reliable, but also convenient for subsequent disassembly and maintenance.

[0037] The track 1 is fixedly mounted on the side of the track plate 5 away from the sleeper 2. This design forms a stable support structure between the track and the base device. This structure can effectively resist the tilting force and vibration in the inclined shaft and ensure the flatness and stability of the track.

[0038] In the specific implementation, in the design of the starting foundation device of the inclined shaft TBM, adjacent sleepers 2 are fixedly connected by connecting steel bars 6. By connecting the adjacent sleepers 2 by connecting steel bars 6, an integral structure can be formed, and the connection strength between the sleepers 2 is increased, thereby improving the stability of the entire track system. During the excavation process of the inclined shaft TBM, the track 1 needs to withstand huge pressure and vibration from the tunnel boring machine. By connecting the sleepers 2 into a whole by connecting steel bars 6, these pressures and vibrations can be dispersed, the bearing capacity of the track 1 can be improved, and the possibility of track deformation and damage can be reduced.

[0039] In addition, in order to facilitate inspection and maintenance, the present application also fixedly installs an inspection channel 10 at the starting section of the tunnel. The design of the inspection channel 10 takes into account both the convenience of personnel passage and the effective protection of the device.

[0040] The inclined shaft TBM launching foundation device provided in this application has the advantages of stable structure, convenient installation, safety and reliability, etc. Through practical application, the device can effectively solve the problem of unstable foundation device of inclined shaft TBM launching section, improve the safety and efficiency of the project, and provide strong technical support for the construction of inclined shaft projects.

[0041] The present application effectively improves the stability and safety of the starting foundation structure of the inclined shaft TBM equipment through a series of connection and reinforcement measures. First, the embedded plate 3 is closely connected to the inclined shaft foundation structure. This connection method ensures the stability of the foundation structure and provides a solid foundation for subsequent installation and fixation. Next, the connection between the arc plate 7 and the embedded plate 3 not only enhances the rigidity of the overall structure, but also makes the structure more compact and stable. In order to further enhance the strength and stability of the connection, reinforcing ribs 8 are particularly used to reinforce the connection parts. The presence of the reinforcing ribs 8 not only increases the strength of the connection, but also effectively resists external stress and vibration, thereby ensuring the long-term stability of the overall structure.

[0042] In addition, the connection design between the arc plate 7 and the sleeper leg 11 is also a highlight of the present application. This connection method not only simplifies the installation process, but also improves the overall stability of the structure. The sleeper oblique leg 4 cleverly connects the arc plate 7 and the sleeper 2 to form a stable and reliable support structure. In the setting of the track 1, the track 1 is precisely mounted on the sleeper 2 and fixed by the track pressure plate 5. This fixing method not only ensures the flatness and stability of the track 1, but also effectively prevents the risk of deformation or derailment of the track 1 during the movement of the TBM equipment.

[0043] In summary, this application achieves the stability of the foundation structure and the non-deformation of the track through a series of innovative connection and reinforcement measures, providing a safe and stable foundation for the launch of the TBM equipment. This not only improves the safety performance of the equipment, but also provides a more reliable and efficient solution for inclined shaft TBM construction.
