Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a water-saving lock suitable for hilly areas. Background Technology

[0002] In the field of shipping engineering, traditional lock systems, due to their single water release mode, face significant drawbacks in waterways with substantial water level differences (typically exceeding 10 meters) or limited water supply. Such locks consume tens of thousands of cubic meters of water per operation, leading to an imbalance between upstream and downstream water bodies, posing a severe challenge to the sustainability of inter-basin water transfer projects, waterways in arid regions, and cascade hubs. To address this issue, the industry has proposed lock systems integrating water-saving pool structures, reducing water consumption per navigation session to 40%-70% of traditional methods through water recycling technology. However, their practical engineering application remains limited by structural adaptability under complex terrain conditions.

[0003] Analysis of geographical distribution characteristics shows that existing water-saving locks are mostly located in two typical areas: firstly, plains traversed by artificial canals (such as inter-basin water diversion projects); and secondly, steep-slope river sections formed by natural river canyons (such as hilly and mountainous areas). Their commonality lies in the need to construct water storage units through large-scale earthwork engineering—usually employing symmetrically distributed, recessed water-saving pools. Construction in plains areas requires excavating shallow underground spaces along both sides of the waterway axis, while in hilly and canyon areas, large-section excavations of the mountainside are necessary to embed a closed water storage structure. The latter faces the following technical bottlenecks:

[0004] 1. Complexity of geological engineering:

[0005] Construction of water-saving reservoirs in canyon areas requires penetrating rock strata or fractured zones. Due to the heterogeneity of the rock mass structure, local collapses or expansion of seepage channels are easily triggered during excavation (such as the softening of fractured rock masses upon contact with water), leading to a surge in support costs. In addition, mechanical crushing of hard rock strata is inefficient, and vibrations generated by traditional blasting techniques may damage the stability of adjacent hydraulic structures.

[0006] 2. Operation and maintenance reachability deficiencies:

[0007] Embedded water-saving tanks often employ a fully enclosed design, with maintenance access limited to narrow vertical shafts or horizontal corridors. This makes it difficult for conventional maintenance equipment (such as dredging machinery and leakage detectors) to directly access the work area. Long-term operation requires manual, high-risk manual work for tasks such as silt removal and lining crack repair, significantly increasing maintenance costs and safety risks.

[0008] 3. Insufficient coordination of the hydraulic system:

[0009] When multiple water-saving pools are connected in series, the existing water conveyance corridors cannot achieve precise water flow distribution. Especially in steep river sections where the water level changes rapidly, hydraulic impact between water-saving pools is likely to occur, leading to increased wear on the gate opening and closing mechanisms.

[0010] In current engineering practice, although water-saving efficiency can be improved by increasing the number of water-saving pools (such as the use of four-stage series water storage units in a certain canal project), the resulting problems such as extended construction period and decreased structural reliability have not yet been systematically resolved. Therefore, there is an urgent need to develop a new water-saving lock structure system that takes into account water-saving performance, construction economy, and ease of operation and maintenance. Utility Model Content

[0011] The purpose of this invention is to overcome the technical problems of existing water-saving lock structures that lead to large construction workload, high cost, and high difficulty in later operation and maintenance when used in hilly and mountainous canyon areas, and to provide a water-saving lock suitable for hilly areas.

[0012] This utility model provides a water-saving lock suitable for hilly areas, including a lock chamber, an elevated water-saving pool on one side of the lock chamber, and a low-level water-saving pool on the other side of the lock chamber. The lock chamber is separated from the elevated water-saving pool on one side and the low-level water-saving pool on the other side by a lock wall. The elevated water-saving pool and the low-level water-saving pool are both located on the opposite side of the lock wall, which are mountain slopes.

[0013] This utility model of a water-saving lock, designed for applications in hilly and canyon areas with limited space, centrally positions the lock chamber and water-saving pool within the canyon, specifically between the two sides of the mountain. The water-saving pool and lock chamber are separated by a gate wall. Essentially, the lock chamber is formed between two parallel gate walls, while the water-saving pool is formed between the gate wall and the mountain slope. The gate wall and mountain slope serve as the sidewalls of the water-saving pool, which can be an open structure with an open top. Compared to existing water-saving locks that require large-section excavation of the mountain to form a closed water-saving pool structure, this utility model achieves a two-stage water-saving mode by placing high and low water-saving pools on both sides of the lock chamber between the mountains. During construction, only a small area of ​​excavation, leveling, and shotcrete support is required on the mountain slope, reducing the amount of construction work and lowering costs. Furthermore, the open water-saving pool facilitates the access of maintenance personnel and equipment, reducing operation and maintenance costs and improving safety.

[0014] Preferably, the upstream of the gate wall is connected to the upper gate head, the downstream of the gate wall is connected to the lower gate head, the upper gate head is provided with water-retaining dams on both sides, and the lower gate head is provided with retaining walls on both sides.

[0015] Preferably, the upstream of the dam on one side of the upper gate head is connected to a first main navigation wall, and the upstream of the dam on the other side of the upper gate head is connected to a first auxiliary navigation wall, and an upstream navigation channel communicating with the gate chamber is formed between the first main navigation wall and the first auxiliary navigation wall.

[0016] Preferably, a second main navigation wall is connected downstream of the retaining wall on one side of the lower gate head, and a second auxiliary navigation wall is connected downstream of the retaining wall on the other side of the lower gate head. A downstream navigation channel communicating with the lock chamber is formed between the second main navigation wall and the second auxiliary navigation wall.

[0017] Preferably, a water conveyance corridor is provided at the bottom of the gate wall, which connects the high-level water-saving pool, the gate chamber, and the low-level water-saving pool.

[0018] Preferably, the water conveyance corridor is equipped with a gate.

[0019] Preferably, the gate wall includes a first wall segment, a second wall segment, and a third wall segment integrally connected from top to bottom. The thickness of the second wall segment is greater than that of the first wall segment and the third wall segment. The second wall segment is disposed above the foundation, and the third wall segment is embedded in the foundation.

[0020] Preferably, a plurality of first anchor rods are connected between the third wall segment and the foundation.

[0021] Preferably, the bottom of the outer eaves of the second wall section is provided with a downwardly protruding anchor block, which is anchored in the foundation.

[0022] Preferably, a slope lining is provided on the mountain slope, and the slope lining is connected to the mountain slope by a number of second anchor rods.

[0023] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0024] This invention provides a water-saving lock suitable for hilly areas. In applications with limited space in hilly canyon regions, the lock chamber and water-saving pool are centrally located within the canyon, between the two sides of the mountain. The water-saving pool and lock chamber are separated by a gate wall. Alternatively, the lock chamber can be understood as being formed between two parallel gate walls, while the water-saving pool is formed between the gate wall and the mountain slope. The gate wall and mountain slope can serve as the side walls of the water-saving pool, which can be an open structure with an open top. Compared to existing water-saving locks that require large-section excavation of the mountain to form a closed water-saving pool structure, this invention creates a two-stage water-saving mode by placing high and low water-saving pools on both sides of the lock chamber between the mountains. Construction only requires small-scale excavation and leveling of the mountain slope and shotcrete support, reducing the amount of construction work and costs. Furthermore, the open water-saving pool facilitates the access of maintenance personnel and equipment, reducing operation and maintenance costs and improving safety. Attached Figure Description

[0037] This embodiment provides a water-saving lock suitable for hilly areas.

[0038] Figure 1 A three-dimensional schematic diagram of the water-saving lock (the bottom of the water-saving pool and the slope of the mountain are not shown); Figure 2 A top-view diagram of a water-saving lock; Figure 3 A schematic diagram of the cross-section of a water-saving lock.

[0039] like Figures 1 to 3 As shown in the figure, the water-saving lock for hilly areas described in this embodiment includes a lock chamber 1. A high-level water-saving pool 2 is located on one side of the lock chamber 1, and a low-level water-saving pool 3 is located on the other side of the lock chamber 1. That is, the lock chamber 1 is situated between the high-level water-saving pool 2 and the low-level water-saving pool 3 on both sides. The lock chamber 1 is separated from both the high-level water-saving pool 2 on one side and the low-level water-saving pool 3 on the other side by lock walls 4. Here, the water-saving lock has two parallel lock walls 4, one of which is located between the high-level water-saving pool 2 and the lock chamber 1. The other gate wall 4 is located between the low-level water-saving pool 3 and the gate chamber 1, and the gate chamber 1 is formed between the two gate walls 4; the other side of the high-level water-saving pool 2 and the low-level water-saving pool 3 relative to the gate wall 4 is a mountain slope 5. Here, for the high-level water-saving pool 2, one side wall is one of the gate walls 4, and the other side wall is a mountain slope 5. Similarly, for the low-level water-saving pool 3, one side wall is another gate wall 4, and the other side wall is also a mountain slope 5.

[0040] This utility model of a water-saving lock, designed for use in hilly and canyon areas with limited space, centrally positions the lock chamber 1 and the water-saving pool within the canyon, specifically between the two sides of the mountain. The water-saving pool and lock chamber 1 are separated by a lock wall 4. Essentially, the lock chamber 1 is formed between two parallel lock walls 4, while the water-saving pool is formed between the lock wall 4 and the mountain slope 5. The lock wall 4 and the mountain slope 5 serve as the side walls of the water-saving pool, which can be an open structure with an open top. Compared to existing water-saving locks that require large-section excavation of the mountain to form a closed water-saving pool structure, this utility model's water-saving lock achieves a two-stage water-saving mode by placing high-level and low-level water-saving pools 3 on both sides of the lock chamber 1 between the mountains. During construction, only a small area of ​​excavation, leveling, and shotcrete support is required on the mountain slope 5, reducing the amount of construction work and lowering costs. Furthermore, the open-type water-saving pool facilitates the access of maintenance personnel and equipment, reducing operation and maintenance costs and improving safety.

[0041] In this embodiment, the upstream of the gate wall 4 is connected to the upper gate head 6, and the downstream of the gate wall 4 is connected to the lower gate head 7. Water-retaining dams 8 are provided on both sides of the upper gate head 6, and retaining walls 9 are provided on both sides of the lower gate head 7. Here, the upper gate head 6 and the lower gate head 7 are provided upstream and downstream of the gate wall 4, respectively. The water-retaining dams 8 on both sides of the upper gate head 6 and the retaining walls 9 on both sides of the lower gate head 7 can also form the side walls of the water-saving pool. That is to say, the water-retaining dams 8, retaining walls 9, gate wall 4 and the mountain slope 5 can together form the four walls of the water-saving pool.

[0042] In this embodiment, the upstream of the dam 8 on one side of the upper gate head 6 is connected to the first main navigation wall 10, and the upstream of the dam 8 on the other side of the upper gate head 6 is connected to the first auxiliary navigation wall 11. An upstream navigation channel 12 communicating with the lock chamber 1 is formed between the first main navigation wall 10 and the first auxiliary navigation wall 11. The downstream of the retaining wall 9 on one side of the lower gate head 7 is connected to the second main navigation wall 13, and the downstream of the retaining wall 9 on the other side of the lower gate head 7 is connected to the second auxiliary navigation wall 14. A downstream navigation channel 15 communicating with the lock chamber 1 is formed between the second main navigation wall 13 and the second auxiliary navigation wall 14. Here, main navigation walls and auxiliary navigation walls are provided upstream of dam 8 and downstream of retaining wall 9. Among them, the first main navigation wall 10 and the first auxiliary navigation wall 11 are upstream navigation walls, and the second main navigation wall 13 and the second auxiliary navigation wall 14 are downstream navigation walls. The orientation of the first main navigation wall 10 and the second main navigation wall 13 is consistent with the direction of the waterway. The first auxiliary navigation wall 11 and the second auxiliary navigation wall 14 are both arc-shaped structures, forming a semi-funnel-shaped opening between the main navigation wall and the auxiliary navigation wall as a guide channel to guide ships in and out of lock chamber 1. Specifically, the first main navigation wall 10 and the first auxiliary navigation wall 11 form the upstream guide channel 12, and the second main navigation wall 13 and the second auxiliary navigation wall 14 form the downstream guide channel 15. Both the upstream guide channel 12 and the downstream guide channel 15 are connected to lock chamber 1, and ships can enter and exit lock chamber 1 through the upstream guide channel 12 and the downstream guide channel 15.

[0043] In this embodiment, a water conveyance corridor 16 is provided at the bottom of the gate wall 4, which connects the high-level water-saving pool 2, the gate chamber 1 and the low-level water-saving pool 3. Specifically, the water conveyance corridor 16 is located at the middle position in the length direction of the gate wall 4, and is formed by extending downward and bending from the water inlet at the bottom of the water-saving pool. Multiple water inlets are formed at the bottom of the gate chamber 1 along the length direction of the gate chamber 1.

[0044] In this embodiment, a gate (not shown in the figure) is provided in the water conveyance corridor 16; a gate system 25 is provided in the gate wall 4 above the water conveyance corridor 16, and the gate can be raised or lowered through the gate system 25 to control the opening and closing of the water conveyance corridor 16.

[0045] In this embodiment, the gate wall 4 includes a first wall segment 17, a second wall segment 18, and a third wall segment 19 integrally connected from top to bottom. The thickness of the second wall segment 18 is greater than that of the first wall segment 17 and the third wall segment 19. The second wall segment 18 is located above the foundation 24, and the third wall segment 19 is embedded in the foundation 24.

[0046] Here, the gate wall structure can be divided into a first wall section 17, a second wall section 18, and a third wall section 19 according to the different thicknesses of each part. The second wall section 18 protrudes towards the interior of the water-saving pool, and its thickness is significantly greater than that of the first wall section 17 and the third wall section 19. The second wall section 18 sits on the foundation 24. The third wall section 19 is located below the second wall section 18 and is embedded in the foundation 24. It can be understood that the cooperative structure formed by the second wall section 18 and the third wall section 19 anchors the entire gate wall 4 in the foundation 24. The protruding part of the second wall section 18 is pressed firmly on the foundation 24 by gravity, which is equivalent to a gravity gate wall structure. The third wall section 19 can be regarded as a lining gate wall structure. The two together achieve the anchoring of the entire gate wall 4 structure in the foundation 24.

[0047] Optionally, multiple first anchor rods 20 are connected between the third wall segment 19 and the foundation 24. Since the wall thickness of the third wall segment 19 is thinner than that of the second wall segment 18, after embedding it into the foundation 24, in order to enhance the anchoring effect of the third wall segment 19 in the foundation 24, multiple first anchor rods 20 can be pre-embedded on the contact surface between the third wall segment 19 and the foundation 24 before the gate wall 4 is poured. After the gate wall 4 is poured, one end of the first anchor rod 20 is embedded in the concrete of the third wall segment 19, and the other end extends into the foundation 24 to achieve anchoring of the third wall segment 19. The first anchor rod 20 can be perpendicular to the contact surface between the third wall segment 19 and the foundation 24, and multiple first anchor rods 20 can be evenly distributed on the contact surface between the third wall segment 19 and the foundation 24.

[0048] Optionally, the bottom of the outer eaves of the second wall section 18 is provided with a downwardly protruding anchor block 21, which is anchored in the foundation 24. The outer eaves of the protruding part of the second wall section 18, that is, the end of the second wall section 18 that extends into the water-saving pool, has a downwardly protruding anchor block 21. The anchor block 21 can be embedded in the foundation 24 as the second wall section 18 sits on it, thereby anchoring the second wall section 18. The cross-sectional shape of the anchor block 21 can be formed into an inverted triangle or inverted trapezoid, and its sharp lower end can be inserted into the foundation 24 to facilitate the anchoring of the second wall section 18. It can also be understood that the second wall section 18 can be engaged with the foundation 24 by the anchor block 21, and together with the first anchor rod 20 installed on the third wall section 19, the overall fixation of the gate wall structure can be achieved.

[0049] In this embodiment, a slope lining 22 is provided on the mountain slope 5. The slope lining 22 is connected to the mountain slope 5 by multiple second anchor rods 23. That is, multiple second anchor rods 23 connect the slope lining 22 and the mountain slope 5. After the mountain slope 5 is excavated and leveled, shotcrete is poured to form the slope lining 22, which is a concrete slope protection structure. In order to improve the stability of the slope lining 22 and its fixed connection with the mountain, multiple second anchor rods 23 can be pre-embedded at the pouring position before the shotcrete is poured. One end of the second anchor rod 23 extends into the mountain rock and soil for anchoring, and the other end is poured and buried in the slope lining 22 for fixation. The second anchor rods 23 can improve the stability and anchoring performance of the slope lining 22 and avoid deformation, cracking and other problems caused by factors such as temperature changes.

[0050] The working principle of the water-saving ship lock is explained in detail below:

[0051] When the upstream reservoir of the water-saving lock is at a high water level, such as the Baise Reservoir being between 214m (flood control level) and 228m (normal storage level), the water level difference between the reservoir and the downstream channel is large. To avoid releasing too much water downstream during lock operation, the water-saving lock adopts a water-saving operation mode, which can use the water-saving pool to regulate the head. Specifically, when the lock releases water, the water in lock chamber 1 is first released to the high-level water-saving pool 2, then to the low-level water-saving pool 3, and the remaining part is released downstream. When the lock stores water, water is first poured into lock chamber 1 from the low-level water-saving pool 3, then into lock chamber 1 from the high-level water-saving pool 2, and the remaining part is replenished by the upstream reservoir.

[0052] When the upstream reservoir of the water-saving lock is at a low water level, such as the Baise Reservoir being located in the range of 203m (minimum navigable water level) to 214m (flood limit water level), the difference between the reservoir water level and the downstream channel water level is small, and direct discharge downstream will not cause excessive water waste. Therefore, the lock can be operated in a non-water-saving mode, that is, neither the high-level water-saving pool 2 nor the low-level water-saving pool 3 participates in the discharge and filling of the lock chamber 1. When discharging water, all the water in the lock chamber 1 is discharged to the downstream channel, and when filling water, water is directly poured into the lock chamber 1 from the upstream reservoir.

[0053] In summary, this utility model provides a water-saving lock suitable for hilly areas. Under the limited space conditions of hilly and canyon areas, the lock chamber and water-saving pool are centrally located within the canyon, between the two sides of the mountain. The water-saving pool and lock chamber are separated by a gate wall. Alternatively, the lock chamber can be understood as being formed between two parallel gate walls, while the water-saving pool is formed between the gate wall and the mountain slope. The gate wall and mountain slope can serve as the side walls of the water-saving pool, which can be an open structure with an open top. Compared to existing water-saving locks that require large-section excavation of the mountain to form a closed water-saving pool structure, this utility model's water-saving lock forms a two-stage water-saving mode by placing high and low water-saving pools on both sides of the lock chamber between the mountains. During construction, only a small area of ​​excavation, leveling, and shotcrete support is required on the mountain slope, reducing the amount of construction work and lowering construction costs. Furthermore, the open water-saving pool facilitates the access of maintenance personnel and equipment, reducing operation and maintenance costs and improving safety.

[0054] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
