Description

Technical Field

[0001] The invention belongs to the technical field of rail tunnels, and in particular relates to a shield tunnel system. Background Art

[0002] According to the current "Highway Tunnel Design Specifications", emergency parking lanes, vehicle crossways and pedestrian crossways must be set up at certain intervals in long and extra-long highway tunnels for disaster prevention and rescue and operation and maintenance. Dangerous situations in long and extra-long highway tunnels not only seriously threaten people's lives and property safety, but also cause huge damage to traffic facilities and human production activities, reduce users' trust in the safety performance of the tunnel, and cause adverse social impacts.

[0003] The track mechanism in the common tunnel structure is a double-track track structure and a single-track track structure. Among them, evacuation passages are arranged on both sides of the double-track track structure tunnel, and evacuation passages are arranged on one side of the single-track track structure tunnel to meet the needs of personnel evacuation and maintenance of engineering personnel when the train stops in the tunnel; drainage ditches are arranged on both sides of the track in the double-track track structure and the single-track track structure to collect and discharge the leaked water in the tunnel structure, but the evacuation passages in the tunnel structure are arranged on both sides of the track, and there is no physical isolation between them and the tunnel. The engineering personnel who carry out maintenance can only enter the tunnel from the tunnel entrance or the auxiliary tunnel to complete the maintenance during the window time of train operation, which makes the maintenance time of the engineering personnel very short, affects the normal maintenance of the tunnel, and is not conducive to the execution of emergency maintenance. At the same time, the above-mentioned evacuation passages occupy a small area and can only be passed by foot. This undoubtedly delays the rescue time of seriously injured people in distress, and they may die because of missing the best rescue time. These have greatly restricted the application of existing railway tunnel structures, reduced the service life of tunnel structures, increased the opening and maintenance costs of tunnel structures, and restricted the application of high-speed trains in existing railway tunnel structures. Summary of the invention

[0004] The present invention provides a shield tunnel system, which adds a special multifunctional channel in the existing tunnel structure, guides the mobile device with the help of a guide monorail, realizes the transportation of people, completes equipment maintenance or emergency rescue, etc., and solves the technical problems that the evacuation channel and the maintenance channel in the existing tunnel structure are shared, which affects the normal maintenance of the tunnel and is not conducive to the execution of emergency rescue.

[0023] Considering the convenience of construction, the guide monorail 33 is spliced ​​by multiple sections of I-shaped guide rails 331. Each section of the I-shaped guide rail 331 is arranged in a lying state and is supported by multiple embedded mounting frames 332 arranged at intervals. In this way, the two side surfaces of the lying I-shaped guide rail 331 can act as rolling contact surfaces, cooperating with the roller pair 41 arranged at the bottom of the moving device 4 to reduce the friction during the guiding process.

[0024] An I-shaped guide rail 331 and a moving device 4 of appropriate size are designed according to the space size of the vehicle driving area. The guide monorail 331 can be set in the middle of the vehicle driving area. The buried part of the pre-embedded mounting frame 332 is a four-corner support structure, and its exposed part can be a U-shaped support plate, and its free end is fixedly connected to the middle cross plate of the I-shaped guide rail 331, such as a threaded connection. In this way, the entire structure is very simple and can effectively reduce construction costs.

[0025] The roller pair 41 can be arranged at the center of the mobile device through a folding mechanism, and the folding mechanism is used to realize the folding of the roller pair.

[0026] A step surface is set at the connection between the vehicle area and the pedestrian area to separate the walking of people and the operation of vehicles as much as possible to prevent collisions between people and vehicles. At the same time, the vehicle area is set close to the center of the shield tunnel, and the pedestrian area is set away from the center of the shield tunnel to ensure that mobile devices have more space to facilitate the transportation of large equipment and other devices.

[0027] The mobile device 4 includes a plurality of transport units with a quadrilateral structure. The four-side arms of each transport unit are arranged on the base plate in a detachable or foldable structure, and the roller pairs can be arranged on the bottom surface of the base plate to facilitate the loading of passengers or equipment. Mechanical interfaces and connecting heads are also arranged on the outer sides of the front and rear arms, which cooperate with each other to connect multiple transport units to each other and realize the external hanging function.

[0028] In addition, a special side support 42 can be provided, on the top surface of which a connecting head for cooperating with the mechanical interface of the transport unit is provided, and on the bottom surface a plurality of movable wheels are provided. With the help of the cooperation between the mechanical interface and the connecting head, the transport unit can be erected on the side support, and then the transport unit can be moved by pushing it manually, so that the transport unit in bad conditions such as accidental damage can be conveniently transported to the maintenance site.
