Description

Technical Field

[0001] The present invention relates to a passenger terminal applicable to an environment with an extremely large water level difference and an arrangement method, and is applicable to the technical field of passenger terminal construction. Background Art

[0002] With the construction of cascade hydropower stations such as Wudongde, Baihetan, Xiluodu, and Xiangjiaba in the lower reaches of the Jinsha River, deep water channels with extremely large water level drops have gradually formed in the reservoir area. To promote the development of tourism economy with waterways as the channel, cruise ships as the carrier, and terminals as the connection, the construction of large-scale passenger terminals in the reservoir area is being carried out in an orderly manner. Affected by the operation and scheduling of hydropower stations such as power generation and flood control, the water level difference between the high water level and the low water level of the waterway in the reservoir area is close to 60 meters, far exceeding the large water level difference terminals of 20 - 30 meters in the conventional sense. How to build a safe, comfortable and reasonable large-scale passenger terminal in the reservoir area with such an extremely large water level drop is an engineering problem currently faced.

[0003] Most of the existing passenger terminal solutions are arranged within the water level drop range of less than 30 meters. When the water level difference is less than 15 meters, the terminal can adopt the arrangement method of a vertical quay wall, or the combination of a floating dock and steps. In this way, the berthing position of the passenger ship is relatively fixed, and the shoreline used by the terminal is relatively short. When the water level drop is between 15 - 30 meters, the terminal mostly adopts the arrangement method of a ramp, or the combination of a floating dock and a floating bridge. When a ramp is adopted, the passenger ship berths at different positions of the ramp as the water level rises and falls. Considering the comfort of passenger passage, the slope of the ramp terminal should be limited within a reasonable range, which results in a very long ramp. When the combination of a floating dock and a floating bridge is adopted, passengers get on and off the ship through the floating dock and the floating bridge. At this time, due to the large water level difference, the length of the floating bridge is long, and a large water area space is required.

[0004] Currently, no passenger terminal arrangement solution for the water level drop between 30 - 60 meters has been seen. All existing solutions consider the water level difference within 30 meters. For example, the new large water level difference passenger terminal based on a vertical elevator group proposed in the utility model patent (CN 211846778U) considers the situation of a water level drop of 10 - 30 meters. The passenger terminal ship-shore connection solution based on a floating pontoon and steps disclosed in the invention patent (CN109795628A) is also not applicable to super-large passenger terminals with a water level drop exceeding 30 meters.

[0005] In fact, although theoretically a ramp arrangement can be adopted for a passenger terminal with a 60-meter water level drop. However, at this time, due to the huge water level drop, the length of the ramp is very long. If it is arranged along the shore, valuable shoreline resources will be wasted; when the ramp extends into the river channel, the river channel width is often insufficient or it will directly affect the navigation of the waterway, and such a long ramp is likely to have an adverse impact on the local hydrological environment and riverbed evolution. Summary of the Invention

[0006] The technical problem to be solved by the present invention is: in view of the above problems, to provide a passenger terminal applicable to an environment with an extremely large water level difference and a layout method.

[0007] The technical solution adopted by the present invention is: a passenger terminal applicable to an environment with an extremely large water level difference, characterized in that: it has a high water level berthing platform and a low water level berthing platform that can adapt to a certain water level drop. The low water level berthing platform is arranged near the high water level berthing platform. The topmost layer of the low water level berthing platform is connected upward to the bottom layer of the high water level berthing platform, and the top layer of the high water level berthing platform is connected to the land area through a connecting trestle.

[0008] The high water level berthing platform is an upright frame berthing platform, which has a multi-layer high-piled frame structure and a connecting passage connecting each layer inside the high-piled frame structure.

[0009] The connecting passage includes an internal circular road connecting each layer inside the high-piled frame structure and available for vehicles to drive, and a staircase connecting each layer inside the high-piled frame structure.

[0010] The low water level berthing platform is a ramp berthing platform, which has a number of ramps distributed vertically and parallel to each other. The lowest point of each ramp is the designed lowest water level. The ramps are connected by ramp staircases, and the topmost ramp is connected to the high water level berthing platform.

[0011] The low water level berthing platform is an upright frame berthing platform, which has a multi-layer high-piled frame structure and a connecting passage connecting each layer inside the high-piled frame structure.

[0012] The connecting passage includes a staircase connecting each layer inside the high-piled frame structure.

[0013] On the top surface of the high water level berthing platform, there are a tourist distribution center, a hotel affiliated to the tourist distribution center, other affiliated facilities of the tourist distribution center, and parking spaces.

[0014] When at the low water level, the passenger ship is berthed alongside on both sides of the low water level berthing platform. After the passengers enter the low water level berthing platform, they move to the topmost layer of the low water level berthing platform, and enter the high water level berthing platform from the topmost layer of the low water level berthing platform, and then move to the topmost layer of the high water level berthing platform. Thus, the process of passengers getting off the ship is completed; the process of passengers getting on the ship is the opposite;

[0015] When the water level rises to the high water level berthing platform, the passenger ship is berthed alongside on both sides of the high water level berthing platform. After the passengers enter the high water level berthing platform, they move to the topmost layer of the high water level berthing platform. Thus, the process of passengers getting off the ship is completed; the process of passengers getting on the ship is the opposite.

[0016] The present invention also provides a layout method for a passenger terminal applicable to an environment with an extremely large water level difference, and the layout method includes the following steps:

[0017] Obtain the basic information for the layout of the passenger terminal;

[0018] According to the basic information for the layout of the passenger terminal, determine the respective design boundaries of the high and low water level berthing platforms;

[0019] According to the respective design boundaries of the high and low water level berthing platforms, construct a dimensional analysis model of the passenger terminal;

[0020] Solve the dimensional analysis model to generate the main layout dimensions and schemes of the passenger terminal.

[0021] Furthermore, the basic information for the layout of the passenger terminal includes topographic and geological information, surrounding water area status information, meteorological and hydrological information, design high water level and design low water level, designed passenger throughput, berth grade and ship type dimensions.

[0022] Furthermore, the step of determining the respective design boundaries of the high and low water level berthing platforms according to the basic information for the layout of the passenger terminal specifically includes:

[0023] According to the topographic and geological information, design high water level and low water level of the terminal, determine the respective design water level drops of the high water level berthing platform and the low water level berthing platform, as well as their combined form;

[0024] According to the meteorological and hydrological information, calculate the respective operation days of the high and low water level berthing platforms;

[0025] According to the designed passenger throughput, berth grade and operation days, calculate the number of berths;

[0026] Furthermore, the step of constructing a dimensional analysis model of the passenger terminal according to the respective design boundaries of the high and low water level berthing platforms is specifically:

[0027] Construct a dimensional analysis model of the high water level berthing platform from the dimensions of length, width and number of layers;

[0028] Construct a dimensional analysis model of the low water level berthing platform from the dimensions of length, width and number of layers;

[0029] Construct a dimensional analysis model of the internal circular road from the dimensions of length, width and slope.

[0030] Furthermore, the step of solving the dimensional analysis model to generate the main layout dimensions and schemes of the passenger terminal specifically includes:

[0031] Determine the parameter values in the dimensional analysis model;

[0032] Calculate the main layout dimensions of the high and low water level berthing platforms and the internal circular road according to the parameter values;

[0033] Carry out the layout plan of the passenger terminal according to the main layout dimensions.

[0034] The beneficial effects of the present invention are as follows: by setting a high water level berthing platform and a low water level berthing platform that are interconnected and can both adapt to a certain water level drop, the terminal can adapt to a super-large water level drop.

[0035] When the ramp is designed to simultaneously meet the needs of passenger walking and vehicle passage, the slope of the ramp is usually relatively gentle, and the relatively gentle slope results in a very long length of the ramp. The present invention meets the berthing requirements of ships in a certain water level drop interval by setting a high water level berthing platform, reduces the water level drop interval of the ramp, thereby shortening the length of the ramp, avoiding problems such as obstruction of navigation that may be caused by using an ultra-long ramp terminal, and also saving shoreline resources to a large extent.

[0036] When the ramp is designed for only passenger walking, in the prior art, the ramp can be arranged relatively steep by setting steps and other forms to reduce its length. However, when the ramp is arranged too steeply, the landing points of the passenger ship will be very limited. Especially when the scale of the passenger terminal is large and two or more berths need to be arranged along the shore at the same time, the number of passenger landing points will be limited, and the gathering and dispersal speed of passengers getting on and off the ship will be affected. In the present invention, by setting multiple ramps that are distributed up and down and parallel to each other, the berthed passenger ships can all find multiple landing points, thereby accelerating the speed of passengers getting on and off the ship, reducing the waiting time of passengers, and improving the comfort of passengers.

[0037] The terminal of the present invention can be entirely built in the water area, without occupying or occupying less of the already very scarce land resources; it is conducive to the construction of large-scale passenger terminals, and the top surface space of the vertical frame berthing platform can be used to create characteristic tourist attractions.

[0038] The method for arranging a passenger terminal with a super-large water level drop provided by the present invention determines the design boundaries of the high and low water level berthing platforms by obtaining the basic information for arranging the passenger terminal, and then respectively constructs size analysis models for the high water level berthing platform, the low water level berthing platform, and the internal circular road. By solving the size analysis models, the main layout dimensions and plans of the passenger terminal are generated, thereby providing the feasibility of the layout plan of the passenger terminal in an environment with a super-large water level drop, and improving the convenience and comprehensive efficiency of the terminal plan layout.

[0046] This embodiment is a passenger terminal suitable for environments with extremely large water level differences, a high-water docking platform and a low-water docking platform arranged near the high-water docking platform, and both the high-water docking platform and the low-water docking platform are constructed on the water area through pile foundations.

[0047] In this example, the high water level docking platform adopts an upright frame docking platform. The upright frame docking platform has a nine-story high-pile frame structure that can adapt to a water level difference of 30 meters. The layers of the upright frame docking platform are connected by connecting channels.

[0048] In this embodiment, the connecting passage includes an internal ring road connecting each layer in the high-pile frame structure and for vehicles to travel, and a frame staircase connecting each layer in the high-pile frame structure.

[0049] In this case, the starting point of the internal circular road is located at the internal circular road patio at the center of the top surface of the upright docking platform, and then gradually descends to the next level of the frame structure according to a certain slope. After reaching the junction of the internal circular road and the frame stairs, it then turns back and continues to descend according to a certain slope, and repeats this cycle until it reaches the end of the internal circular road. The end of the internal circular road is located at the bottom layer of the high-pile frame structure close to the low-water level docking platform.

[0050] In this example, the framed staircases on the same floor are all connected by roads. The entrance of the framed staircase is located in the staircase patio on the top surface of the vertical docking platform, and its lowest floor is the same as the lowest floor of the internal circular road.

[0051] In this embodiment, the low-water-level docking platform is arranged directly in front of the high-water-level docking platform and adopts a ramp docking platform. The ramp docking platform has a ramp multi-layer frame structure composed of 4 ramps distributed vertically and parallel to each other. The lowest points of each ramp are adapted to the design lowest water level. The ramps are connected by ramp staircases, and ramp tread patios are provided on the ramps corresponding to the ramp staircases. The highest point of the topmost ramp is connected to the end of the internal circular road on the high-water-level docking platform.

[0052] If the geological conditions are suitable, this embodiment can also adopt a solid ramp. The length of the ramp docking platform is determined according to the water level drop it adapts to and the slope of the ramp.

[0053] In this embodiment, a passenger distribution center, a hotel affiliated to the passenger distribution center, other affiliated facilities of the passenger distribution center, parking spaces, etc. are arranged on the top surface of the vertical docking platform in the high-water-level docking platform.

[0054] The operation method of the passenger terminal in this embodiment is as follows:

[0055] S1. When at low water level, the passenger ship berths alongside on both sides of the ramp docking platform. Passengers enter the corresponding floor of the ramp multi-layer frame structure through a boarding plank or directly, and then climb to the topmost ramp through the ramp staircase via the patio. The passenger shuttle bus departs from the top surface of the vertical frame docking platform, passes through the internal circular road patio, the internal circular road, the end of the internal circular road, and the highest point of the ramp in sequence to reach the passenger waiting area. After the shuttle bus turns around and stops stably, the passengers get on the bus, and then the shuttle bus loads them to the passenger distribution center. Thus, the process of passengers getting off the ship is completed, and the process of passengers getting on the ship is the opposite.

[0056] S2. When the water level gradually rises to the high-water-level docking platform, the docking positions of the passenger ship on both sides of the ramp docking platform gradually approach the vertical frame docking platform. After the ramp docking platform is flooded, the passenger ship berths alongside on both sides of the vertical frame docking platform. Thereafter, as the water level rises, the position of the passenger ship remains unchanged, only the floors where it berths are different due to the rise and fall of the water level. After the passenger ship berths, passengers enter the floor corresponding to the current water level through a boarding plank or directly, and then walk along the aisle to the connection point between the internal circular road and the staircase. After the shuttle bus arrives, the passengers get on the bus; then the shuttle bus drives along the internal circular road to the passenger distribution center. The process of passengers getting on the ship is the opposite of this process.

[0057] Embodiment 2: This embodiment is basically the same in structure as Embodiment 1, except that in this embodiment, the low-water-level docking platform adopts an upright-frame docking platform. That is, the passenger terminal with a large water-level drop is composed of two upright-frame docking platforms and a passenger distribution center. The two upright-frame docking platforms are relatively close to each other, and are respectively applied to the high water level and the low water level, and the two are connected by a road. Among them, the upright-frame docking platform at the high water level is the same as that in the above solution, and the passenger distribution center can also be arranged on the top surface of the upright-frame docking platform at the high water level. The top surface of the low-water-level upright-frame docking platform is effectively connected to the bottom layer of the high-water-level upright-frame docking platform by a road. The internal stratification and circular road of the low-water-level upright-frame docking platform can be the same as those of the high-water-level upright-frame docking platform.

[0058] When the water level of the terminal is at the low water level, the passenger ship berths alongside the low-water-level upright-frame docking platform. Passengers enter the corresponding floor through a boarding plank or directly from the passenger ship, and then are transferred to the passenger distribution center through a shuttle bus via the interconnected internal circular road. When the water level gradually rises and submerges the low-water-level upright-frame docking platform, the passenger ship berths alongside the high-water-level upright-frame docking platform.

[0059] Embodiment 3: If the terrain and geological conditions of the location where the passenger terminal is located are suitable, the passenger terminal with a large water-level drop is directly composed of the upright-frame docking platform and the passenger distribution center in Embodiment 1, that is, the low-water-level docking platform is cancelled, and all the water-level drops are realized by the upright-frame docking platform. At this time, the number of floors of the upright-frame docking platform is more than that of the original technical solution. The passenger ship berths alongside the upright-frame docking platform throughout.

[0060] The embodiment of the present invention also provides an arrangement method for a passenger terminal applicable to an environment with a large water-level difference. The arrangement method includes steps S10 to S40:

Specifically, it includes:

[0063] S21. Calculate the total water level drop ΔH of this passenger terminal according to the designed high and low water levels. ΔH = H2 - H1, where H2 is the designed high water level of the terminal and H1 is the designed low water level of the terminal. In this case, ΔH = 60m.

[0064] S22. Determine the lowest designed water level H3 of the high water level berthing platform and its corresponding water level drop ΔH1 according to the topographic conditions of the location of the proposed terminal. ΔH1 = H2 - H3; then determine the corresponding water level drop ΔH2 of the low water level berthing platform. ΔH2 = H3 - H1. In this case, ΔH1 = 30m and ΔH2 = 30m.

[0067] If ΔH1 < ΔH, then this passenger terminal consists of a high water level berthing platform, a low water level berthing platform and a passenger distribution center. Among them, when the topography at the location of the proposed low water level berthing platform is relatively flat, the low water level berthing platform adopts the layout of a ramp berthing platform; when the topography at the location of the proposed low water level berthing platform is relatively steep and suitable for arranging an upright frame platform, the low water level berthing platform can be arranged as an upright frame platform.

[0068] In this case, ΔH1 < ΔH. According to the topographic conditions, the low water level berthing platform is arranged as a ramp.

[0069] S24. Determine the respective operation days of the high and low water level berthing platforms according to the water level fluctuation curve of the river where the terminal is located and meteorological and hydrological information such as wind, rain, fog and waves.

[0070] S25. Calculate the number of berths N of the passenger terminal according to the designed passenger throughput, berth grade and operation days in accordance with the "General Design Code for River Ports (JTS166 - 2020)".

Formula a4 Among them, , , , , , , are the actual values of the main layout dimensions of the high and low water level docking platforms and the internal circular road; S43. Carry out the layout of the passenger terminal according to the values of the main layout dimensions.

2. The layout method of the passenger terminal applicable to the ultra-large water-level difference environment according to claim 1, characterized in that: When at the low water level, the passenger ship is berthed alongside on both sides of the low-water-level wharf. After the passengers enter the low-water-level wharf, they move to the topmost layer of the low-water-level wharf and enter the high-water-level wharf from the topmost layer of the low-water-level wharf, and then move to the topmost layer of the high-water-level wharf, thus completing the process of passengers getting off the ship; the process of passengers getting on the ship is the opposite. When the water level rises to the high-water-level dock, passenger ships are moored alongside both sides of the high-water-level dock. After passengers enter the high-water-level dock, they move to the topmost floor of the high-water-level dock, thus completing the process of passengers disembarking; the process of passengers boarding is the opposite.
