Description

Technical Field

[0001] The present invention relates to complex urban road tunnels, and in particular to a rapid three-dimensionally linked shield tunnel rescue and operation maintenance channel and method. Background Art

[0002] Complex urban road shield tunnels and submarine road shield tunnels face complex geological conditions and high construction safety risks. Therefore, it is necessary to fully utilize the tunnel corridor below the shield lane as a pedestrian and vehicle evacuation corridor. Given that complex urban tunnels are generally located in weak surrounding rock or complex ground environments, the construction of cross passages, especially vehicle cross passages, should be reduced. However, the reduction of cross passages poses a challenge in achieving rapid rescue and providing convenient operation and maintenance during operation. In addition, the current tunnel corridor below the shield tunnel and the upper carriageway can only be connected in the open-cut section, not in the higher-risk shield section, which also makes rescue inconvenient.

[0003] Therefore, it is necessary to design a new fast three-dimensional linkage shield tunnel rescue and operation and maintenance channel and method to overcome the above problems. Summary of the Invention

[0004] The purpose of the present invention is to overcome the defects of the prior art and provide a fast three-dimensional linkage shield tunnel rescue and operation and maintenance channel and method. The present invention at least solves some of the problems in the prior art.

[0005] The present invention is achieved in that:

[0006] The present invention provides a fast three-dimensional linkage shield tunnel rescue and operation channel, comprising a service tunnel, an upward main line tunnel, and a downward main line tunnel. The service tunnel, the upward main line tunnel, and the downward main line tunnel are arranged in parallel. The service tunnel is located between the upward main line tunnel and the downward main line tunnel. The service tunnel entrance is directly connected to the ground. One end of the shield section of the main line tunnel is directly connected to the ground through an open-cut section. The shield section and the open-cut section are connected through a working well. The other end of the shield section of the main line tunnel is directly connected to the ground through a drilling and blasting section. The shield section and the drilling and blasting section are connected through a demolition well. The main line tunnel is connected to the cavern, and the upper layer is the carriageway layer, and the lower layer is the pipe gallery layer. The pipe gallery layer includes the lower evacuation corridor of the main line tunnel. The carriageway layer is connected to the lower evacuation corridor of the main line tunnel through an evacuation staircase. The carriageway layer is connected to the service tunnel through several vehicle cross passages. At the working shaft or the dismantling cavern, the road surface height of the service tunnel is lowered to the same level as the road surface height of the lower evacuation corridor of the main line tunnel. At the working shaft or the dismantling cavern, the service tunnel is connected to the lower evacuation corridor of the main line tunnel through the lower evacuation corridor connecting cross passages.

[0007] Furthermore, at the dismantling cavern, the lower evacuation corridor connecting the transverse passage is set in conjunction with the dismantling cavern.

[0008] Furthermore, at the working shaft, the lower evacuation corridor connecting the transverse passage is set in conjunction with the working shaft.

[0009] Furthermore, along the length direction of the shield tunnel, at a certain position in the middle of the shield section, the road surface height of the service tunnel is lowered to be equal to the road surface height of the lower evacuation corridor of the main line tunnel, and is connected to the lower evacuation corridor of the main line tunnel through a connecting cross passage of the lower evacuation corridor.

[0010] Furthermore, the shield section of the main line tunnel is provided with a number of shield vehicle cross passages. At the shield vehicle cross passages, the road surface height of the service tunnel is equal to the road surface height of the main line tunnel lane layer, and the main line tunnel lane layer is connected to the service tunnel through the shield vehicle cross passages.

[0011] Furthermore, in the open-cut section, the longitudinal slope inclination of the service tunnel is greater than the longitudinal slope inclination of the main line tunnel.

[0012] Furthermore, the open-cut section of the main line tunnel is provided with an open-cut vehicle cross passage. At the open-cut vehicle cross passage, the road surface height of the service tunnel is equal to the road surface height of the main line tunnel lane layer, and the main line tunnel lane layer is connected to the service tunnel through the open-cut vehicle cross passage.

[0013] Furthermore, in the drilling and blasting section, the road surface height of the service tunnel is equal to the road surface height of the main line tunnel lane layer, the drilling and blasting section of the main line tunnel is provided with a drilling and blasting vehicle cross passage, and the main line tunnel lane layer is connected to the service tunnel through the drilling and blasting vehicle cross passage.

[0014] The present invention also provides a rapid three-dimensional linkage shield tunnel rescue and operation method, which includes a rescue method and an operation method. The rescue method is: at the main line accident point, personnel enter the lower evacuation corridor of the main line tunnel through the evacuation stairs, then enter the service tunnel through the lower evacuation corridor connecting the cross passage, and then evacuate to the tunnel entrance through the service tunnel.

[0015] Furthermore, the operation and maintenance method is as follows: the operation and maintenance vehicle enters through the service tunnel, then enters the main line tunnel through the vehicle cross passage between the service tunnel and the main line tunnel, and then passes through the main line tunnel lane layer to the main line tunnel operation and maintenance point.

[0016] The present invention has the following beneficial effects:

[0017] 1. The present invention realizes the interconnection of the lane layer of the main tunnel, the evacuation corridor under the main tunnel and the service tunnel through the ingenious arrangement of the evacuation corridor under the main tunnel, the service tunnel and the vehicle cross passage, forming an evacuation and rescue as well as daily operation and maintenance channel with vertical linkage and three-dimensional connection, which greatly improves the evacuation and rescue efficiency and the convenience of daily operation and maintenance.

[0018] 2. The present invention can eliminate pedestrian cross passages, and the number of vehicle cross passages can be reduced compared to the standard.

[0019] 3. In the evacuation state, evacuees can enter the evacuation corridor in the lower part of the main tunnel via the evacuation stairs and achieve rapid evacuation by rescue vehicles, etc. Due to the high efficiency of personnel evacuation, the shield section does not need to be equipped with a pedestrian crosswalk.

DETAILED DESCRIPTION

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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 technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0042] like Figures 1-19 , Embodiment 1 of the present invention provides a fast three-dimensional linkage shield tunnel rescue and operation channel, including a service tunnel 11, an upward main line tunnel 10, and a downward main line tunnel 10. The service tunnel 11, the upward main line tunnel 10, and the downward main line tunnel 10 are arranged in parallel. The service tunnel 11 is located between the upward main line tunnel 10 and the downward main line tunnel 10. The entrance of the service tunnel 11 is directly connected to the ground. One end of the shield section 3 of the main line tunnel is directly connected to the ground through the open-cut section 5. The shield section 3 and the open-cut section 5 are connected through a working well 4. The other end of the shield section 3 of the main line tunnel is directly connected to the ground through the drilling and blasting section 1. The shield section 3 and the drilling and blasting section 1 are connected. Section 1 is connected through the dismantling cavern 2. The mainline tunnel 10 is divided into two layers, the upper layer being the carriageway layer and the lower layer being the pipe gallery layer. The pipe gallery layer includes the lower evacuation corridor 13 of the mainline tunnel. The carriageway layer is connected to the lower evacuation corridor 13 of the mainline tunnel via an evacuation staircase 14. The carriageway layer is connected to the service tunnel 11 via several vehicle-carrying transverse passages. At the working shaft 4 or the dismantling cavern 2, the road surface height of the service tunnel 11 is lowered to the same level as the road surface height of the lower evacuation corridor 13 of the mainline tunnel. At the working shaft 4 or the dismantling cavern 2, the service tunnel 11 is connected to the lower evacuation corridor 13 of the mainline tunnel via a lower evacuation corridor connecting transverse passage 16. Preferably, at the dismantling cavern 2, the lower evacuation corridor connecting transverse passage 16 is provided in conjunction with the dismantling cavern 2. At the working shaft 4, the lower evacuation corridor connecting transverse passage 16 is provided in conjunction with the working shaft 4.

[0043] If necessary, preferably, along the length direction of the shield tunnel, at a certain position in the middle of the shield section 3, the road surface height of the service tunnel 11 is lowered to be equal to the road surface height of the lower evacuation corridor 13 of the main line tunnel, and is connected with the lower evacuation corridor 13 of the main line tunnel through the lower evacuation corridor connecting cross passage 16, so that the lower evacuation corridor 13 of the main line tunnel can be directly connected to the ground as soon as possible.

[0044] The shield section 3 of the main line tunnel 10 is provided with a number of shield vehicle cross passages 8. At the shield vehicle cross passages 8, the road surface height of the service tunnel 11 is equal to the road surface height of the main line tunnel lane layer. The main line tunnel lane layer is connected to the service tunnel 11 through the shield vehicle cross passages 8.

[0045] In the open-cut section 5, the longitudinal slope of the service tunnel 11 is greater than that of the mainline tunnel 10. The service tunnel 11 exits the tunnel entrance via the longitudinal slope and reaches the surface directly, achieving an early exit through the service tunnel 11. The open-cut section 5 of the mainline tunnel 10 is equipped with an open-cut vehicle transverse passage 9. At this transverse passage 9, the road surface of the service tunnel 11 is equal to that of the mainline tunnel's lane level. The mainline tunnel's lane level is connected to the service tunnel 11 via the open-cut vehicle transverse passage 9.

[0046] In the drilling and blasting section 1, the road surface height of the service tunnel 11 is equal to the road surface height of the main line tunnel lane layer. The drilling and blasting section 1 of the main line tunnel 10 is provided with a drilling and blasting vehicle transverse passage 7, and the main line tunnel lane layer is connected to the service tunnel 11 through the drilling and blasting vehicle transverse passage 7.

[0047] Complex urban shield tunnels utilize a three-tunnel parallel layout. The mainline tunnel's shield section 3 features a double-deck layout, with the upper deck serving as a carriageway and the lower deck as a utility corridor. An evacuation corridor 13 for the mainline tunnel is located in the middle of the utility corridor, with an evacuation staircase 14 located on one side, providing pedestrian access between the upper carriageway and the mainline tunnel's lower evacuation corridor 13. A service tunnel 11, with its entrance leading directly to the surface, is located between the upper and lower shield tunnels.

[0048] The mainline tunnel shield section 3 can directly reach the ground through the open-cut section 5, and the shield section 3 and the open-cut section 5 are connected through the working shaft 4. The mainline tunnel shield section 3 can also directly reach the ground through the drilling and blasting section 1, and the shield section 3 and the drilling and blasting section 1 are connected through the dismantling cavern 2. At the working shaft 4 or the dismantling cavern 2, the road surface elevation of the service tunnel 11 is equal to the elevation of the evacuation corridor 13 below the mainline tunnel to achieve the connection between the service tunnel 11 and the evacuation corridor 13 below the mainline tunnel. According to the needs of evacuation and operation and maintenance, the elevation of the service tunnel 11 can be partially lowered in the middle of the shield section 3 to achieve the same elevation as the road surface elevation of the service tunnel 11 and the evacuation corridor 13 below the mainline tunnel.

[0049] Based on the needs of comprehensive disaster prevention and operation and maintenance of the shield section, as well as hydrogeological conditions, vehicle cross passages are set at regular intervals. Most sections of the road surface of service tunnel 11 are at the same elevation as the lane level of mainline tunnel 10. In principle, the vehicle cross passages also function as pedestrian cross passages. In the open-cut section 5, the longitudinal slope of service tunnel 11 is greater than that of mainline tunnel 10, enabling rapid ground access. At the same elevation as the road surface of open-cut section 5, open-cut vehicle cross passage 9 is set to connect service tunnel 11 with the lane level of mainline tunnel 10. In the drill-and-blast section, the road surface of service tunnel 11 is at the same elevation as that of mainline tunnel 10, and a drill-and-blast vehicle cross passage 7 is set to connect service tunnel 11 with the lane level of mainline tunnel 10.

[0050] Figure 1-Figure 4The longitudinal section of the tunnel is shown in Figure 1. The middle section is the tunnel shield section 3, the left section is the drill and blast section 1, and the right section is the open cut section 5. The shield section 3 and the drill and blast section 1 are connected by the dismantling cavern 2, and the shield section 3 and the open cut section 5 are connected by the working shaft 4. Figure 5-Figure 7 ), near the dismantling cavern 2 and the working shaft 4 and, if necessary, at the same elevation as the road surface of the service tunnel 11 in the middle of the shield tunnel and the road surface of the evacuation corridor 13 in the lower part of the shield section (e.g. Figures 8-10 ).

[0051] Figure 5-Figure 7 This is a cross-sectional view of the shield tunnel. The service tunnel 11 is located between the uplink and downlink main tunnels 10. The main tunnel 10 is divided into two layers, the upper layer is the carriageway layer, and the lower layer is the pipe gallery layer. The middle of the pipe gallery layer is the lower evacuation corridor 13 of the main tunnel. The carriageway layer of the main tunnel 10 and the lower evacuation corridor 13 of the main tunnel are connected by an evacuation staircase 14. When evacuation is required, personnel enter the lower evacuation corridor 13 of the main tunnel through the evacuation staircase 14 and quickly leave the tunnel by evacuation vehicles.

[0052] Figures 8-10 To dismantle the location of cavern 2, a cross-sectional view of the connection between the lower evacuation corridor 13 of the main line tunnel and the service tunnel 11 is provided. Here, the road surface elevation 12 of the local service tunnel is lowered to be basically flush with the road surface of the lower evacuation corridor 13 of the main line tunnel.

[0053] Figure 11-13 This is a plan diagram of the interconnection between the main line tunnel 10 lane level and the service tunnel 11.

[0054] Figure 14-16 This is a plan diagram of the interconnection between the lower evacuation corridor 13 of the main line tunnel and the service tunnel 11. Near the dismantling cavern 2 and the working shaft 4 and, when necessary, in the middle of the shield tunnel, the road surface elevation of the service tunnel 11 is the same as the road surface elevation of the lower evacuation corridor 13 of the shield section. The upper and lower main line tunnels 13 and the service tunnel 11 are connected through the lower evacuation corridor connecting cross passage 16.

[0055] At the dismantling cavern 2, a lower evacuation corridor connecting transverse passage is set in combination with the dismantling cavern 15, and at the working shaft 4, a lower evacuation corridor connecting transverse passage is set in combination with the working shaft 17.

[0056] By adjusting the longitudinal section of the service tunnel (adjusting the longitudinal road surface height of the service tunnel), the lane level of the up and down main line tunnel 10 and the service tunnel 11 are interconnected through the vehicle cross passages (drilling and blasting vehicle cross passage 7, shield vehicle cross passage 8, open-cut vehicle cross passage 9). Figure 11-13), the lower evacuation corridor 13 of the up and down main line tunnels and the service tunnel 11 are interconnected through the lower evacuation corridor connecting transverse passage 16, thereby realizing the functions of rapid evacuation and rescue as well as daily operation and maintenance.

[0057] Embodiment 2 of the present invention provides a rapid three-dimensional linkage shield tunnel rescue and operation method, the rescue method is: at the main line accident point, personnel enter the lower evacuation corridor of the main line tunnel through the evacuation stairs, then enter the service tunnel through the lower evacuation corridor connecting the cross passage, and then evacuate to the tunnel entrance through the service tunnel; the operation and maintenance method is: the operation and maintenance vehicle enters through the service tunnel, then enters the main line tunnel through the vehicle cross passage between the service tunnel and the main line tunnel, and then passes through the main line tunnel lane layer to the main line tunnel operation and maintenance point.

[0058] Figure 17-19 This is a schematic diagram of the operation and maintenance and evacuation routes, which illustrates the route for personnel to quickly evacuate to the tunnel entrance through the service tunnel 11 in the event of an accident in the main line tunnel 10. For example, at the main line accident point 19 in the figure, personnel enter the lower evacuation corridor 20 of the main line tunnel via the evacuation stairs, then enter the service tunnel 21 through the lower evacuation corridor connecting the cross passage set at the working shaft, and then evacuate to the tunnel entrance 22 through the service tunnel.

[0059] Figure 17-19 It also illustrates the need for an operation and maintenance point in the mainline tunnel, and the route for operation and maintenance vehicles to enter the mainline tunnel 10 through the service tunnel 11. As shown in the figure, the operation and maintenance vehicles enter 23 through the service tunnel, then enter the mainline tunnel 24 through the shield vehicle cross passage between the service tunnel and the mainline tunnel, and then pass through the mainline tunnel lane level to the mainline tunnel operation and maintenance point 25.

[0060] The key technical points of the present invention are as follows: (1) Setting up a service tunnel: In order to improve the convenience of disaster prevention, rescue and operation and maintenance of complex urban tunnels, a service tunnel is generally set up between the up and down main tunnels, and the service tunnel 11 has an opening directly connected to the ground. (2) The service tunnel is connected to the lower evacuation corridor of the shield: Taking advantage of the fact that the opening of the service tunnel 11 is directly connected to the ground, the road surface elevation of the service tunnel at the working shaft 4 or the dismantling cavern 2 is equal to the road surface elevation of the lower evacuation corridor 13 of the main tunnel, and the lower evacuation corridor 13 of the main tunnel is directly connected to the ground. According to the length of the shield tunnel, the needs of evacuation and operation and maintenance, the road surface elevation of the service tunnel 11 can be partially lowered in the middle of the shield section to achieve the same elevation of the service tunnel 11 and the lower evacuation corridor 13 of the main tunnel, thereby achieving direct connection with the ground as soon as possible. In the evacuation state, evacuees can enter the lower evacuation corridor 13 of the main tunnel through the evacuation stairs 14 and achieve rapid evacuation by means of rescue vehicles, etc. Due to the high efficiency of personnel evacuation, in principle, a pedestrian cross passage can be omitted in the shield section. (3) Using a vehicle cross passage to connect the service tunnel and the main tunnel carriageway layer: The shield section 3 can be appropriately provided with a shield vehicle cross passage 8. At the location of the vehicle cross passage, the elevation of the main tunnel pavement is basically the same as that of the service tunnel pavement. The carriageway layer of the main tunnel 10 is connected with the service tunnel 11. In this way, small operation and maintenance vehicles can directly enter the main tunnel 10 through the service tunnel 11, thereby improving the timeliness of evacuation or daily operation and maintenance. (4) A cross passage for vehicles is set up in the open-cut section 5 and the drill-and-blast section 1: the service tunnel 11 of the open-cut section adopts a larger longitudinal slope than the main line tunnel 10 to achieve an early exit from the ground, and a cross passage for vehicles 9 is set up at the same elevation to connect the service tunnel 11 with the lane level of the open-cut section main line tunnel; the service tunnel 11 of the drill-and-blast section is at the same elevation as the lane level of the main line tunnel 10, and the main line tunnel 10 is connected to the service tunnel 11 through the drill-and-blast cross passage 7, thereby realizing a rapid evacuation or daily maintenance channel at the lane level of the entire tunnel.

[0061] Overall tunnel design: Determine the horizontal and vertical sections of the tunnel based on its functional positioning and traffic diversion, determine the cross-section of the tunnel based on the exchange flow, and determine the segmented construction method based on the hydrogeological conditions of the tunnel.

[0062] Tunnel disaster prevention, evacuation and operation and maintenance strategies: Determine whether to set up an intermediate service tunnel 11 based on the tunnel's functional positioning, fire rescue timeliness, and operation and maintenance convenience. Consider the rescue timeliness and hydrogeological conditions to determine the spacing of the shield vehicle cross passage 8 in the shield section. Determine whether to lower the elevation of the service tunnel and the elevation of the evacuation corridor 13 in the lower part of the main tunnel in the middle of the shield section 3 based on the length of the shield section 3 and the hydrogeological conditions.

[0063] Tunnel disaster prevention, evacuation, and operation and maintenance plan: The tunnel adopts a three-tunnel parallel layout, with a service tunnel 11 located in the middle. The pavement elevation of the service tunnel 11 at the working shaft 4, the dismantling cavern 2, and the middle of the shield section 3 is equal to the pavement elevation of the evacuation corridor 13 below the mainline tunnel. The pavement elevation of the service tunnel 11 at the shield section vehicle cross passage 8, the drilling and blasting section vehicle cross passage 7, and the open-cut section vehicle cross passage 9 is equal to the pavement elevation of the mainline tunnel 10 lane level. The service tunnel 11 is connected in series to form a three-dimensional interconnected disaster prevention and evacuation channel and operation and maintenance channel below the mainline tunnel 13 and the lane level, which is directly connected to the ground through the service tunnel 11 or the mainline tunnel 10 portal.
