Description

Technical Field

[0001] The utility model relates to the technical field of components of a ship lock, in particular to a ship lock flow separation wall and a ship lock. Background Art

[0002] A ship lock is a hydraulic engineering facility used to overcome the water level difference between different river sections in a natural water system, allowing ships to sail smoothly between rivers with large water level differences. The basic working principle of a ship lock is similar to the principle of lifting a bucket, that is, the closed lock chamber is used to separate the space where the ship is located from the upstream and downstream, and by regulating the water level in the lock chamber, the ship is like in a huge elevator, achieving a smooth transition from the low water level area to the high water level area.

[0003] The lock includes a lock barrier wall. The lock barrier wall is an important part of the lock facility, which is mainly used to maintain the stability of the water level inside the lock and control the water flow state to ensure the safety and effectiveness of the lock operation. The lock barrier wall is mainly used to: 1. Isolate the pilot channel from the main channel water flow of the external river or lake, 2. Maintain the appropriate water depth in the pilot channel, 3. Guide the ship to travel correctly, 4. Reduce the impact of cross flow on ships, and 5. Maintain the structural stability of the entire lock.

[0004] However, the existing ship lock isolation walls are all integrally cast structures, so the construction period is long. After the isolation walls are damaged in the later stage, it is not easy to repair. Utility Model Content

[0005] The utility model aims to solve the problems in the prior art that the pile foundations of the ship lock isolation wall are all integrally cast structures, the construction period is long, and it is inconvenient to repair after damage, and provides a ship lock isolation wall and a ship lock.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A ship lock flow barrier comprises a plurality of pile foundations arranged at intervals, the lower ends of the pile foundations extend into the rock layer below the flow barrier, a first crown beam is arranged on the top of the pile foundation, a plurality of columns arranged at intervals are connected to the top surface of the first crown beam, a prefabricated plug plate is inserted between two adjacent columns, and the thickness of the prefabricated plug plate is less than the thickness of the pile foundation.

[0008] The pile foundation located outside the rock formation is a permeable area. The first capping beam is arranged at the top of the pile foundation, which can transfer the force of the column to the pile foundation more evenly, facilitating the stability of the cut-off wall. A precast insertion plate is arranged between two adjacent columns. Compared with directly pouring the lining for cut-off, it can improve the construction efficiency and shorten the construction period. Moreover, the thickness of the precast insertion plate is smaller than that of the column, which can save construction costs and is also convenient for construction. And the precast insertion plate is inserted between two adjacent columns. When the precast insertion plate is damaged, only the precast insertion plate needs to be replaced. Compared with the prior art that requires all replacements, it can save costs and improve the replacement efficiency.

[0009] As a preferred embodiment of the present utility model, a bayonet is arranged on one side of the column facing each other, and the size of the bayonet matches the size of the precast insertion plate.

[0010] The bayonet is used for clamping the precast insertion plate, which can ensure the fixation of the precast insertion plate as much as possible and is conducive to ensuring the cut-off effect of the cut-off wall.

[0011] As a preferred embodiment of the present utility model, the cross-section of the bayonet is in the shape of "匚".

[0012] As a preferred embodiment of the present utility model, a recessed component is arranged on the inner side wall of the bayonet, and a protruding component is arranged on the precast insertion plate corresponding to the recessed component on the inner wall of the bayonet.

[0013] The inner side wall of the bayonet refers to the two opposite sides of the bayonet. When a recessed component is arranged on the inner side wall of the bayonet and a protruding component is arranged correspondingly on the precast insertion plate, the positioning of the precast insertion plate when it is placed inside the bayonet can be realized.

[0014] As a preferred embodiment of the present utility model, cement mortar is poured between the bayonet and the precast insertion plate.

[0015] Grouting is arranged in the gap between the bayonet and the precast insertion plate, so that the precast insertion plate and the column are combined into one body, which is conducive to strengthening the overall stability of the component.

[0016] As a preferred embodiment of the present utility model, a second capping beam is further arranged at the top of the column.

[0017] When a second capping beam is arranged between the column and the pile foundation, the uneven settlement of the column can be avoided as much as possible, which affects the stability of the cut-off wall.

[0018] As a preferred embodiment of the present utility model, spiral bars are arranged inside the pile foundation, and the axis of the spiral bars is parallel to the axis of the pile foundation.

[0019] The spiral reinforcement inside the pile foundation can increase the compression, bending and shear resistance of the pile concrete, especially when resisting seismic loads or lateral soil pressure, which can effectively prevent the premature appearance of cracks and limit the expansion of cracks, thereby improving the integrity and bearing capacity of the pile foundation.

[0020] As a preferred solution of the utility model, the distance between two adjacent pile foundations is 2m.

[0021] A ship lock comprises a ship lock flow barrier as described above.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0023] 1. A ship lock flow barrier wall, which is provided with a first crown beam on the top of the pile foundation, and a plurality of columns are provided at intervals on the top surface of the first crown beam, and prefabricated plug plates are provided between the columns. Compared with the direct casting of the flow barrier lining, the efficiency of construction can be accelerated and the construction period can be shortened. The thickness of the prefabricated plug plate is less than the thickness of the column, which can save construction costs and facilitate construction. The prefabricated plug plate is plugged between two adjacent columns, so when the prefabricated plug plate is damaged, only the prefabricated plug plate can be replaced, which can save costs and improve replacement efficiency compared with the existing technology that requires all to be replaced. The ship lock flow barrier wall solves the problem that the pile foundation of the ship lock flow barrier wall in the existing technology is an integrally cast structure, the construction period is long, and it is inconvenient to repair after damage.

[0024] 2. A ship lock, which uses a ship lock flow barrier wall as described above, is conducive to shortening the construction period and is also convenient for replacement after damage, which is conducive to improving the quality of the ship lock. BRIEF DESCRIPTION OF THE DRAWINGS

The cross-section of the bayonet openings 6 is in the shape of "匚". Cement mortar is poured between the bayonet openings 6 and the precast insert plate 3. As a further preferred solution, on the inner side wall of the bayonet openings 6, there are recessed parts (not shown in the figure), and on the precast insert plate 3, there are protruding parts (not shown in the figure) corresponding to the recessed parts on the inner wall of the bayonet openings 6.

[0041] As Figure 1 shown in the figure, a first capping beam 4 is arranged between the columns 2 and the piles 1. A second capping beam 5 is also provided at the top of the columns 2.

[0042] Spiral bars (not shown in the figure) are arranged inside the piles 1, and the axis of the spiral bars is parallel to the axis of the piles 1.

[0043] The distance between two adjacent piles 1 is 2m.

[0044] In this embodiment, the lock guide wall has a total of 43 piles 1 with a diameter of φ2000mm, all of which are cast-in-place piles. The part of the piles 1 below -9.7m is the rock-socketed section, that is, it extends into the rock stratum below the guide wall; the section from -9.70m to -2.70m is the open section, which allows water flow through; the section from -2.70m to -0.6m is the first capping beam 4, the section from -0.6 to 6.4 is the precast insert plate 3 and the columns 2, and the section from 6.4 to 8.5 is the second capping beam 5.

[0045] For the cast-in-place piles in the rock-socketed section of the piles 1 below -9.7m, a rotary drilling rig is used for construction, and for the open section from -9.7m to -2.7m, a formwork is erected for cast-in-place pile splicing technology.
