Description

Technical Field

[0001] This invention relates to the field of lock architecture design or other related fields, and more specifically, to a recommended method, apparatus, and electronic equipment for determining the top elevation of lock hydraulic structures. Background Technology

[0002] As an important hydraulic structure connecting different water level areas, the design of a ship lock needs to comprehensively consider navigation safety, economy, and ease of operation. The design of the top elevation of the ship lock hydraulic structure is a key aspect, as it directly affects the mooring safety of ships under different operating conditions, the convenience of crew disembarking, the economic cost of the project, and its harmony with the surrounding environment.

[0003] In related technologies, the determination of the top elevation of hydraulic structures in locks is mainly based on the provisions of the industry standard "General Design Code for Locks" (JTJ 305-2001) regarding the maximum navigable water level and the freeboard height of ships. Specifically, the top elevation of hydraulic structures needs to be determined based on the design maximum navigable water level plus a certain freeboard value. This freeboard value is generally selected as the maximum freeboard height of large ships when unloaded, to ensure that the mooring safety of ships can be maintained even under extreme water level conditions.

[0004] However, the design methods in related technologies have certain limitations: 1. Failure to consider the diversity of ship operating conditions: Traditional methods often only consider the freeboard height of large ships in an unloaded state, ignoring the changes in freeboard height under different operating conditions such as full load and ballast. This may lead to inconvenience for crew members to disembark under certain conditions. 2. Insufficient assessment of the needs of small vessels: The design is usually based on the parameters of large ships, without fully considering the hydraulic structure top elevation requirements of small vessels, resulting in inconvenience for small vessels to berth and for crew members to embark and disembark. 3. Poor economic efficiency: Using the freeboard of large ships as the superheight value may cause an unreasonable increase in project costs when a large freeboard height is not required, especially in lock projects with the condition of long-term operation.

[0005] There is currently no effective solution to the above problems. Summary of the Invention

[0033] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0034] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0035] To facilitate understanding of the present invention by those skilled in the art, some terms or nouns involved in the various embodiments of the present invention are explained below:

[0036] Dead Weight Tonnage (DWT) is a metric that measures a ship's cargo-carrying capacity. It represents the total weight of cargo, fuel, fresh water, etc., that a ship can carry when fully loaded, excluding its own weight. In lock design, DWT is used to determine the ship's dimensions, draft, and freeboard, which in turn affects the design of the top elevation of hydraulic structures.

[0037] The Proportional Coefficient Method (PCM) is a statistical analysis method used to calculate the optimal elevation of the top of lock hydraulic structures based on the usage ratio of various ship types and the freeboard height of ships under different operating conditions (fully loaded, ballasted, and unloaded). This method ensures that the design meets the needs of the most commonly used ship types while also accommodating other ship types, and takes into account engineering economics.

[0038] Freeboard height refers to the vertical distance from the waterline to the deck line when a vessel is at a given draft. It is a crucial parameter for assessing a vessel's stability and safety, affecting its mooring capabilities at high water levels and the ease with which crew members can disembark.

[0039] It should be noted that the recommended method and apparatus for the top elevation scheme of lock hydraulic structures in this disclosure can be used in the field of lock structure design when the top elevation of lock hydraulic structures is designed based on the proportional coefficient method, and can also be used in any field other than lock structure design when the top elevation of lock hydraulic structures is designed based on the proportional coefficient method. This disclosure does not limit the application field of the recommended method and apparatus for the top elevation scheme of lock hydraulic structures.

[0040] It should be noted that the information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, stored data, and displayed data) collected in this public disclosure are information and data authorized by the user or fully authorized by all parties. Furthermore, the collection, storage, use, processing, transmission, provision, disclosure, and application of related data all comply with the relevant laws, regulations, and standards of the relevant regions, necessary confidentiality measures have been taken, and they do not violate public order and good morals. Corresponding operation entry points are provided for users to choose to authorize or refuse. For example, this system has interfaces with relevant users or organizations. Before obtaining relevant information, a request to obtain the information needs to be sent to the aforementioned user or organization through the interface, and the relevant information is obtained only after receiving consent from the aforementioned user or organization.

[0041] It should be noted that in this disclosure, customer information is collected and analyzed, and users are provided with corresponding operation entry points to choose whether to agree to or reject the automated decision results; if the user chooses to reject, the process will proceed to the expert decision-making process.

[0042] The following embodiments of the present invention can be applied to recommended systems / applications / equipment for various lock hydraulic structure top elevation schemes. The present invention can be applied to the field of inland waterway engineering, such as in the design and construction of new locks, lock renovation and upgrading, and waterway planning and management.

[0043] This invention enables the precise calculation of freeboard height changes for different ship types under conditions such as full load, ballast, and no load, making the design of the top elevation of lock hydraulic structures more closely aligned with actual needs, thus ensuring navigation safety and improving ease of use.

[0044] Top elevation design based on the proportional coefficient method can effectively reduce engineering costs and avoid the waste of resources caused by excessively high top elevations in traditional design methods, providing a more economical and reasonable choice for project investment decisions.

[0045] This invention, by considering the usage ratios of various ship types, especially the needs of small and large vessels under ballast conditions, significantly improves the convenience of crew disembarking and enhances the user experience. By reasonably lowering the top elevation of the lock's hydraulic structures, making them more harmonious with the surrounding terrain and environment, it not only beautifies the project's appearance but also reduces the risk of obstructed views, facilitating safe operation and maintenance.

[0046] Because this invention designs the top elevation based on the dynamic changes and usage ratios of the ship's freeboard, it has strong applicability and flexibility, and can be adjusted according to the characteristics and needs of different waterways, making it suitable for a wide range of waterway engineering projects.

[0047] The present invention will now be described in detail with reference to various embodiments.

[0048] Example 1

[0049] According to an embodiment of the present invention, a recommended method for determining the top elevation of a lock hydraulic structure is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0050] First, it should be noted that the hydraulic structures of a lock mainly include the upper lock head, lock chamber, lower lock head, upstream navigation wall, upstream berthing pier, downstream navigation wall, and downstream berthing pier. The upper lock head houses the upper gate, and the lower lock head houses the lower gate, forming an enclosed space with the lock chamber. Mooring facilities are installed on the water-facing side and top of the lock chamber to facilitate mooring and meet the needs of vessels for berthing and passage through the lock. The upstream berthing pier is the structure where vessels wait to pass through the lock; mooring facilities are also installed on the water-facing side and top of the upstream and downstream berthing piers to facilitate mooring. The upstream and downstream navigation walls are the navigation structures for vessels entering the lock.

[0051] Setting the top elevation of the lock's hydraulic structures too high makes mooring and unloading ships inconvenient and increases project costs. Conversely, setting it too low lowers costs but increases the risk of ships detaching from their mooring lines, compromising safety and making disembarkation difficult. Therefore, accurately determining the top elevation of the lock's hydraulic structures is crucial for ensuring the safe and smooth passage of ships through the lock and for effectively controlling project costs.

[0052] This embodiment analyzes the hub's scheduling and operation rules to determine the opening time and corresponding water level of the lock, as well as the normal operation time and water level of the ship lock. It then analyzes the normal operation time, water level, and throughput capacity of the ship lock to determine whether it can meet the transportation needs of ships passing through the lock. Next, it analyzes the ship type proportions, determining the top elevation of the ship lock's hydraulic structures based on a high proportion of ship types, and using a small proportion of ship types to verify the top elevation of the ship lock's hydraulic structures.

[0053] In addition, this embodiment can analyze and determine whether the ship has ballast conditions; if the ship can navigate with ballast, the freeboard height after ballast is determined, and then the top elevation of the lock hydraulic structures is determined. If ballast conditions are not met, the top elevation of the lock hydraulic structures is determined based on the unloaded freeboard height.

[0054] Figure 1 This is a flowchart of a recommended method for an optional scheme of the top elevation of a lock hydraulic structure according to an embodiment of the present invention, such as... Figure 1 As shown, the method includes the following steps:

[0055] Optionally, before obtaining the characteristic dimensions of different types of vessels passing through the lock, the recommended method for the top elevation scheme of the lock hydraulic structures also includes: analyzing the water level data of the lock under the proposed top elevation scheme; plotting a monthly average water level curve based on the water level data; analyzing the monthly average water level curve to determine the time period and corresponding water level for the lock operation state, wherein, when the upstream inflow is within a specified range, the lock is controlled to open the spillway to maintain a stable water level at the key lock; when the upstream inflow exceeds a preset threshold, the lock enters the lock operation state; in the lock operation state, based on the characteristic that vessels do not need to berth at the lock hydraulic structures, the top elevation of the lock hydraulic structures is determined for vessel navigation.

[0056] Before obtaining the characteristic dimensions of different lock vessel types, it is necessary to analyze the water level data of the lock under the proposed top elevation scheme. Taking the Baima Hydropower Project as an example, multi-year water level data at the Baima Hydropower Project is collected and evaluated, and the average water level changes each month are analyzed. Through in-depth research on historical hydrological data, the seasonal fluctuation pattern of water level in the water area where the lock is located can be understood, as well as the possible time and frequency of extreme water levels. Then, using the water level data analyzed above, a curve of monthly average water level changes is plotted. Through the intuitive curve, the high-water season and the low-water season, as well as the highest and lowest water levels throughout the year, can be clearly identified.

[0057] In this embodiment, based on the plotted average water level curve and the hydrological characteristics of the Baima Hydropower Station, the operation mode of the lock for different time periods was determined. For example, when the upstream inflow is less than 2 cubic meters per second, the lock does not operate; when the upstream inflow is within the specified range of 2 to 10 cubic meters per second, the Baima Hydropower Station closes the lock to impound water, and the lock operates normally; when the upstream inflow exceeds 10 to 230 cubic meters per second, the lock continues to operate normally, while the spillway is opened to maintain the stability of the water level above the lock; when the upstream inflow exceeds the preset threshold of 230 cubic meters per second, the lock enters the open lock operation state, at which time ships do not need to berth at hydraulic structures to maintain navigation efficiency.

[0058] When the lock is in operation, the hydraulic structures of the lock primarily serve a navigation function, rather than a mooring function. Therefore, according to the "Design Code for Breakwaters and Revetments" (JTS154-2018), the top elevation of the hydraulic structures only needs to be 1 meter higher than the highest navigable water level to ensure that the basic requirements for safe navigation of ships are met. This approach reduces the height of the hydraulic structures while ensuring safe navigation, thus optimizing project costs and aesthetics.

[0059] Step S101: Obtain the characteristic dimensions of different lock-passing vessel types, wherein the characteristic dimensions include at least the freeboard height of the vessel under full load, ballast, or no load conditions.

[0060] Step S101 first obtains the characteristic dimensions of different lock-passing vessel types. These dimensions at least cover the freeboard height of the vessel under full load, ballast, or no-load conditions. The freeboard height refers to the vertical distance from the waterline to the deck line when the vessel is at a certain draft, which is crucial to the safety and maneuverability of the vessel.

[0061] Optionally, the step of obtaining characteristic dimensions of different lock-passing vessel types includes: obtaining the ballast tank capacity of the lock-passing vessel type, and evaluating the freeboard height adjustment range of the lock-passing vessel type under ballast conditions based on the ballast tank capacity.

[0062] It should be noted that obtaining the ballast tank capacity of the lock-transfer vessel type involves collecting specific capacity data for each type of lock-transfer vessel. This is the basis for assessing the adjustable freeboard height of the vessel under ballast conditions. Subsequently, based on the ballast tank capacity, the freeboard height adjustment range of the lock-transfer vessel type under ballast conditions is evaluated. In this embodiment, using the obtained ballast tank capacity, the minimum and maximum freeboard height of the vessel under ballast conditions can be calculated. By analyzing the amount of water that can be injected into the vessel during ballast and how it affects the vessel's draft and freeboard height, the minimum safety requirements for the top elevation of the lock hydraulic structures are determined, ensuring that mooring and operation safety are met even under the most extreme ballast conditions.

[0063] Optionally, before determining the proportion of each type of vessel passing through the lock based on the cargo demand analysis results, the method further includes: analyzing the cargo volume forecast data of the channel to which the lock belongs under the proposed top elevation scheme, as well as the historical records of vessel traffic; and based on the cargo volume forecast data and the historical records of vessel traffic, analyzing the cargo volume data of the channel to which the lock belongs within a specified time period to obtain the cargo demand analysis results.

[0064] The analysis of cargo volume forecast data for the channel to which the proposed top elevation scheme for the lock is located involves predicting the future cargo volume of the channel, estimating its future usage frequency and potential cargo pressure. Based on the cargo volume forecast data and historical vessel traffic records, the analysis examines the cargo volume data of the channel within a specified time period, considering not only future forecasts but also statistical analysis of past vessel traffic. By comparing historical and forecast traffic volumes, the usage frequency and importance of different vessel types within a specific time period (e.g., day, week, or month) can be more accurately assessed. This ensures that the design scheme meets the efficient navigation needs of major vessel types while also accommodating the passage convenience of smaller vessel types.

[0065] Step S102: Based on the results of the cargo volume demand analysis, determine the proportion of each type of vessel passing through the lock.

[0066] In step S102 of this embodiment, a detailed analysis is conducted based on the freight demand analysis results to determine the proportion of each type of vessel passing through the lock. This identifies which vessel types have the highest passage frequency within a specific time period and the contribution of different vessel types to the channel's freight volume. This information is crucial for subsequent design steps, ensuring that the design of the lock's hydraulic structures prioritizes the needs of high-frequency vessel types while also considering the ease of use for low-frequency vessel types.

[0067] Step S103: Based on the ship type proportion and freeboard height, the top elevation of the lock hydraulic structures under different working conditions is calculated using the proportional coefficient algorithm to obtain multiple proposed recommended schemes.

[0068] In step S103 of this embodiment, the Proportional Coefficient Method (PCM) is used to calculate the top elevation of the lock hydraulic structures under different operating conditions, taking into account the proportion of each type of vessel passing through the lock and its freeboard height. Specifically, PCM multiplies the freeboard height of each vessel type by the proportion of that vessel type, and then sums the calculation results for all vessel types to obtain a representative top elevation value. This value can dynamically reflect the changes in freeboard height of different vessel types under different operating conditions (such as fully loaded, ballasted, and unloaded), and how these changes affect the setting of the top elevation of the lock hydraulic structures.

[0069] Optionally, the step of using a proportional coefficient algorithm to calculate the top elevation of the lock hydraulic structures under different working conditions includes: calculating the required top elevation of each type of vessel passing through the lock under different working conditions; and performing a weighted average based on the proportion of each type of vessel in the cargo demand analysis results and the required top elevation of each type of vessel under different working conditions to obtain the top elevation of the lock hydraulic structures under different working conditions.

[0070] In this embodiment, the step of calculating the top elevation of the lock hydraulic structures under different working conditions using the proportional coefficient algorithm can be broken down into calculating the required top elevation for each type of vessel passing through the lock under different working conditions (full load, ballast, and empty load), and performing a weighted average based on the proportion of each vessel type in the cargo demand analysis results and the required top elevation. First, based on the freeboard height and the maximum navigable water level, the top elevation requirements for each vessel type under full load, ballast, and empty load conditions are calculated. For example, for vessels of 1000 DWT and below, if the freeboard height under full load is 1.20 meters and the upstream design maximum navigable water level is 2.00 meters, then the required top elevation for this vessel type under full load conditions is 3.20 meters (2.00 + 1.20); while the top elevation for a 3000 DWT vessel under ballast conditions may be higher, reflecting the changes in freeboard and safe berthing requirements of large vessels.

[0071] Based on the STP (Speed ​​Transfer Point) of each type of vessel passing through the lock and the required top elevation under different operating conditions, a weighted average calculation is performed. For example, for parts such as the lock head and lock chamber, if the STP of a 1500DWT vessel is 39% and the STP of a 3000DWT vessel is 53%, then when calculating the top elevation, the top elevation requirements of these two vessel types under full load, ballast, and empty load conditions will be multiplied by their respective vessel type proportions, and then summed to obtain a top elevation value that integrates the requirements of different vessel types. This ensures that the design of the top elevation can meet the safety requirements of large vessels while also taking into account the ease of use for small vessels and crew members.

[0072] Optionally, after calculating the top elevation of the lock hydraulic structures under different working conditions using the proportional coefficient algorithm, the method further includes: configuring a fixed ladder for the climbing working condition and configuring a movable steel ladder for the descending working condition.

[0073] Considering that under certain operating conditions, the top elevation of the lock's hydraulic structures may require crew members to climb a certain height to reach the mooring facilities, fixed ladders are typically installed in areas with high ship berthing frequency, such as the upstream and downstream berthing piers of the lock. This ensures that crew members can safely and conveniently board and disembark ships under full load or ballast conditions to perform mooring or unmooring operations. Conversely, when the top elevation of the lock's hydraulic structures is relatively low to the ship, i.e., when the ship is unloaded, a ladder must be descended to reach the mooring facilities. In this case, movable steel ladders become necessary. Movable steel ladders can be adjusted according to the relative height difference between the ship and the hydraulic structures, ensuring that crew members can safely board and disembark ships under different water levels and operating conditions. Especially when the ship's draft is shallow and its freeboard is large, movable steel ladders provide a flexible solution, ensuring navigation efficiency and personnel safety.

[0074] Alternatively, the recommended method for the top elevation scheme of the lock hydraulic structures also includes: the maximum height values ​​of the fixed ladder and the movable steel ladder correspond to the top elevation difference of the lock vessel type under different working conditions.

[0075] In this embodiment, in order to solve the problem of inconvenience for boaters to go ashore due to changes in the top elevation of the lock hydraulic structures, fixed ladders and movable steel ladders are introduced as compensation devices. The maximum height of the two is directly related to the difference between the top elevation of the hydraulic structures and the type of boat passing through the lock under different working conditions (fully loaded, ballasted, and empty).

[0076] Step S104: Calculate the investment cost of the lock hydraulic structures corresponding to the top elevation determined in each proposed scheme, and select the scheme with the lowest investment cost as the target top elevation recommended scheme.

[0077] Step S104 of this embodiment involves conducting an economic evaluation of the different top elevation design schemes to determine the optimal top elevation scheme. This involves a detailed cost calculation for each proposed top elevation scheme. When calculating investment costs, the cost of lock hydraulic structures under different top elevation schemes can be estimated based on the "Design Code for Lock Hydraulic Structures" (JTJ 307-2001) and the "Methods for Compiling Budget Estimates for Water Transport Projects" and supporting quotas. The cost estimate covers all project-related expenses, including building materials, labor, equipment, and maintenance, and considers long-term economic factors such as operating costs and potential economic benefits. This embodiment further compares the investment costs of all proposed schemes, aiming to find the scheme with the lowest cost, thus determining an optimal top elevation scheme that meets both the safety and efficiency requirements of ship navigation while also considering the cost-effectiveness of the project. For example, the top elevation scheme determined based on the proportional coefficient method has a lower investment cost than other schemes and meets both safety and navigation requirements; therefore, it is selected as the recommended scheme.

[0078] In this embodiment, the cost calculation and scheme selection process not only focuses on minimizing investment costs, but also considers the practicality of the scheme and its impact on the operation of the lock. A lower top elevation can reduce the amount of engineering work, thereby reducing investment costs, but at the same time, it is necessary to ensure that the safety and navigation efficiency of the lock are not affected under all operating conditions.

[0079] Through the above steps, the characteristic dimensions of different lock-passing vessel types can be obtained. Among them, the characteristic dimensions include at least the freeboard height of the vessel under full load, ballast, or empty conditions. Based on the cargo volume demand analysis results, the proportion of each lock-passing vessel type is determined. According to the vessel type proportion and freeboard height, the top elevation of the lock hydraulic structures under different working conditions is calculated using a proportional coefficient algorithm, resulting in multiple proposed recommended schemes. The investment cost of the lock hydraulic structures corresponding to the top elevation determined in each proposed recommended scheme is calculated, and the scheme with the lowest investment cost is selected as the recommended scheme for the target top elevation. In this embodiment, characteristic dimensional information of different lock-passing vessel types can be obtained, especially their freeboard height under full-load, ballast, or empty-load conditions. Then, based on the prediction of future channel freight volume and the statistics of existing vessel traffic, the proportion of each lock-passing vessel type in navigation is determined. Using a proportional coefficient algorithm, combined with the freeboard height and usage frequency of each vessel type, the top elevation of the lock hydraulic structures under different operating conditions is calculated. This allows for dynamic analysis of the freeboard height under different vessel operating conditions, and by combining this information with the usage frequency of the vessel type, the top elevation of the lock hydraulic structures can be determined in a more refined way. This makes it easier for crew members to go ashore and improves utilization. This solves the technical problem in related technologies where the top elevation of lock hydraulic structures is determined in a fixed way, which does not take into account the freeboard changes of vessels under different operating conditions such as full load and ballast, resulting in inconvenience for crew members to go ashore and affecting utilization.

[0080] The following describes in detail another optional implementation method.

[0081] This invention proposes a method for designing the top elevation of hydraulic structures in ship locks based on the proportional coefficient method. The following uses the Baima Ship Lock project as an example to illustrate this method:

[0082] Step S1: Study the scheduling and operation rules of the hub and determine the lock operation status for different months. Collect multi-year water level data at the Baima Hub, analyze the monthly average water level, and draw a monthly average water level curve.

[0083] Based on the historical data of the hydrological station at Baima Hub, the water inflow conditions in this area can be analyzed. The overall water inflow can be divided into the high water season (July to December) and the low water season (January to June), with March to May being the three driest months of the year.

[0084] Based on the topography and water resource requirements at the Baima Hydropower Station, considering inundation losses and river hydrological characteristics, the water-retaining level of the hydropower station is determined to be 1.5m. When the upstream inflow is <2m³ / h... 3 When the water level is 1.5 m / s, the Baima Dam closes its gates to impound water, and the locks are not operational; when the water level is 2 m / s... 3 / s < upstream flow rate < 10m 3 During the period from March to May, the Baima Dam is closed for water storage, and the ship lock operates under normal conditions; when the water level reaches 10m... 3 / s < upstream flow rate < 230m 3 When the flow rate is / s, the water level upstream of the Baima Hub continues to rise. The ship lock operates under normal conditions, and the spillway is opened to control the discharge, stabilizing the water level upstream of the Baima Hub at 1.5m (June-July, December-February of the following year); when the upstream flow rate is >230m³ / s... 3 The locks are open and operational during the period from August to November.

[0085] Step S2: Elevation of the top of the lock's hydraulic structures during lock operation.

[0086] When the lock is open, ships do not need to berth at the lock's hydraulic structures. The top elevation of the lock's hydraulic structures serves a navigational purpose. According to the "Design Code for Breakwaters and Revetments" (JTS154-2018), its top elevation only needs to be 1m higher than the highest navigable water level. The 20-year flood level is calculated as 1.33m + 1m = 2.33m.

[0087] Step S3: Statistically analyze the characteristic dimensions of representative ship types to determine the requirements for the top elevation of the lock hydraulic structures for different representative ship types. Particular attention should be paid to whether the ship has ballast tanks, as this determines the freeboard height under ballast conditions, as shown in Table 1 below: Ship types of 1000 DWT and below do not have ballast tanks and therefore have no corresponding ballast freeboard height; the ballast freeboard of 1500 DWT ships is 2.50–2.70 m, and that of 3000 DWT ships is 4.04–4.46 m.

[0088] Table 1: Representative Ship Dimensions

[0089]

[0090]

[0091] When a vessel has ballast tanks, the freeboard height can be reduced through ballast, thereby lowering the top elevation of the lock's hydraulic structures. The calculations for the top elevations of the lock's hydraulic structures under unloaded and ballast conditions are shown in Table 2 below. According to the standard algorithm, taking the envelope of the maximum values ​​for each vessel type, the top elevations of the lock head, lock chamber, upstream navigation wall, berthing pier, and anchorage berthing pier should be 7.30m, and the top elevations of the downstream navigation wall, berthing pier, and anchorage berthing pier should be 6.63m. According to the calculation method for ballast tanks, the top elevations of the lock head, lock chamber, upstream navigation wall, berthing pier, and anchorage berthing pier should be 6.46m, and the top elevations of the downstream navigation wall, berthing pier, and anchorage berthing pier should be 5.79m.

[0093]

[0094]

[0095] Step S4: Based on freight volume forecasts, analyze and determine the proportion of vessels passing through each lock. After the waterway is completed, the freight volume is expected to reach 40 million tons by 2050. To meet the freight transport demand, based on the current vessel situation and waterway conditions, the predicted vessel flow structure is shown in Table 3 below: 3000-ton vessels will account for 53%, 1500-ton vessels for 39%, and vessels under 1000 tons for 8%.

[0096] Table 3 Tonnage Structure of Future Canal Vessels

[0097] years Shipments Transport ship numbers average tonnage Less than 1000 tons 1500-ton class 3000-ton class 2050 29605 28195 2800 2256 11560 15789 Ship type proportion 8％ 39％ 53％

[0098] Step S5: Determine the top elevation of the lock's hydraulic structures using the proportional coefficient method. Calculate the top elevations for different ship types, and perform a weighted average according to the ship type proportion to determine the top elevation of the lock's hydraulic structures. Taking the lock head and lock chamber as an example, the weighted average is calculated according to the standard algorithm: 4.80*8% + (5.50 + 5.30) / 2*39% + (6.90 + 7.30) / 2*53% = 6.253m.

[0099] Taking the gate head and gate chamber as examples, the weighted average is calculated according to the ballast algorithm: 4.80*8%+(4.70+4.50) / 2*39%+(6.04+6.46) / 2*53%=5.49m.

[0100] Step S6: Calculate the top elevation of the lock hydraulic structures and the corresponding economic costs determined by each algorithm. The top elevations of the lock hydraulic structures calculated using the standard algorithm, the ballast ratio coefficient method, and the full-load algorithm are shown in Table 4 below.

[0101] Table 4. Statistics on the top elevation of hydraulic structures of the ship lock

[0102]

[0103] Step S7: Rationality analysis and compensation device for the top elevation of the lock hydraulic structures.

[0104] Based on the top elevation of the lock's hydraulic structures determined by the coefficient method, we analyze the full-load, ballast, and empty-load conditions to calculate the elevations required for each ship type to ascend or descend the ramps to reach the shore. See Table 5 below for details, where ascending is represented by positive numbers and descending by negative numbers. For ships of 1000 DWT and below, the full-load condition is calculated as follows: 5.49m - (2.00m + 1.20m) = 2.29m.

[0105] Table 5. Rationality Analysis of the Top Elevation of Lock Hydraulic Structures Determined Based on the Coefficient Method

[0106]

[0107] As shown in Table 5, based on the top elevation of the lock's hydraulic structures determined by the coefficient method, a 3000 DWT vessel requires a downward ladder in both ballast and unloaded conditions, with a maximum downward ladder elevation of 1.81m. For other conditions, an upward ladder elevation is required, with a maximum upward ladder elevation of 2.29m. If the top elevation is set at 7.30m, the maximum upward ladder elevation for vessels of 1000 DWT and below is 7.3 - 3.2 = 3.9m, while for a 3000 DWT vessel fully loaded, the maximum upward ladder elevation is 1.26m.

[0108] Figure 2(a) is an elevation view of an optional fixed ladder according to an embodiment of the present invention; Figure 2(b) is a front view of an optional fixed ladder configuration according to an embodiment of the present invention. As shown in Figure 2(a), the ladder is equipped with multiple movable steps, and each ladder is fitted with multiple angle iron steps, allowing it to be placed on the side of the waterway, near the breast wall. As shown in Figure 2(b), a horizontal baffle is arranged on the upper side of the fixed ladder, and vertical baffles are provided on the left and right sides to ensure the safety of personnel climbing the ladder. This fixed ladder is suitable for upward climbing operations.

[0109] Figure 3 This is a schematic diagram of a movable steel ladder according to an embodiment of the present invention, as shown below. Figure 3 As shown, this movable steel ladder is suitable for use when descending a ship's ladder.

[0110] Step S8: Calculate the cost of the lock hydraulic structures determined by each algorithm and determine the recommended scheme.

[0111] Based on the elevations determined in Table 6, and in accordance with the provisions of the "Design Code for Ship Lock Hydraulic Structures" (JTJ 307-2001), the internal forces and reinforcement of the structures under various working conditions are calculated, and the quantities of concrete, steel reinforcement, and other works for the ship lock hydraulic structures are determined. According to the "Methods for Compiling Budget Estimates for Water Transport Engineering" and its supporting quotas, the investment for each algorithm of the ship lock hydraulic structures is determined, as shown in Table 6 below. The design scheme using the top elevation of the ship lock hydraulic structures determined by the proportional coefficient method can save approximately 38 million yuan in investment.

[0112] Table 6 Investment in Ship Lock Hydraulic Structures (Unit: 100 Million Yuan)

[0113] algorithm Canonical Algorithm proportional coefficient method Full load algorithm Investment amount / 100 million yuan 9.30 8.92 8.83

[0114] It should be noted that for lock projects that are ready for long-term operation, the top elevation of the hydraulic structures can be determined according to the "Design Code for Breakwaters and Revetments" (JTS154-2018) when the locks are in operation. The freeboard height of different vessels under full load, ballast, and empty load conditions should be determined according to the vessel design drawings.

[0115] Additionally, it should be noted that the top elevation of the lock hydraulic structures based on the proportional coefficient method is determined by multiplying the top elevation during ballast by the proportion of ships.

[0116] In this embodiment, the lock is designed to be suitable for long-term operation. The top elevation of the lock's hydraulic structures is determined to meet the requirements for safe and efficient navigation, and is economical. It also takes into account the berthing needs of both large and small vessels. The reasonable determination of the top elevation of the lock's hydraulic structures facilitates the disembarkation of boaters.

[0117] Furthermore, this embodiment can adapt to the berthing needs of ships under full load, empty load and ballast conditions, reasonably determine the top elevation of the lock hydraulic structures, facilitate boaters to go ashore, reduce the top elevation of the lock hydraulic structures, coordinate with the surrounding terrain conditions, and make the overall layout more aesthetically pleasing.
