Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, and in particular to a doorway type flow isolation wall structure. Background Art

[0002] The navigable water flow conditions at the entrance of the pilot channel are the key technical indicators for whether ships can safely enter and exit the navigation facilities. Article 5.3.2 of the transportation industry standard "General Design Specifications for Ship Locks" (JTJ 305-2001) stipulates the maximum flow velocity limit of the water surface at the entrance of the pilot channel. In actual engineering, it is often encountered that the axis of the navigation facility and the axis of the waterway are not in a straight line. It is necessary to connect the axis of the navigation facility and the axis of the waterway through an oblique line or curve at the entrance of the pilot channel. When the hub is discharging, in the entrance of the pilot channel upstream of the navigation facility, due to the suction effect of the hub discharge, a tilt flow occurs in the gate area (the lateral component of the discharge is the cross flow), such as Figure 1 As shown in the figure, in the downstream approach channel gate area of ​​the navigation structure, due to the impact of the hub discharge, the gate area has a tilting flow (the lateral component of the discharge is the cross flow), as shown in the figure. Figure 2 Therefore, due to the limitation of construction conditions, it is easy to have the problem of cross flow in the entrance area exceeding the standard.

[0003] The conventional solution to the above problem is to reserve or install a flow barrier between the hub and the ship lock approach channel. The flow barrier is generally a sloped earth-rock structure or a reinforced concrete pier-slab structure with a hollow bottom. However, the diversion effect of the above two types of flow barriers is poor, and the effect of reducing the lateral flow velocity in the gate area is limited.

[0004] As can be seen from the above, the prior art has the problem that the flow guiding effect of the flow partition wall is relatively poor. Utility Model Content

[0005] The main purpose of the utility model is to provide a door opening type flow isolation wall structure to solve the problem that the flow isolation wall in the prior art has a poor flow guiding effect.

[0007] Furthermore, the shape of the door opening is rhombus.

[0008] Furthermore, the diamond shape of the door opening is inclined toward the downstream of the channel.

[0009] Furthermore, convex ribs extending in the height direction are provided at both ends of the vertical plate, and slots matching the convex ribs are provided at the upper part of the column, and the convex ribs are inserted into the slots to connect and fix the vertical plate to the column.

[0010] Furthermore, the height of the slot is the same as the height of the vertical plate.

[0011] Furthermore, the cross section of the convex rib is an inverted triangle.

[0012] Furthermore, the plurality of columns form a plurality of rows, and the distance between two adjacent columns in each row of columns is different.

[0026] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0027] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0028] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0029] Obviously, the embodiments described above are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0030] In order to solve the problem of poor flow guiding effect of flow partition walls in the prior art, the utility model provides a doorway type flow partition wall structure.

[0031] like Figure 3 to Figure 4As shown, the doorway type flow-isolating wall structure includes a column 10 and a vertical plate 20, both of which are multiple, and the multiple columns 10 are arranged along a straight line to form at least one row, each vertical plate 20 is located at the upper part between two adjacent columns 10, and is detachably connected to the two adjacent columns 10, and the two side surfaces of the vertical plate 20 along the arrangement direction are flush with the two side surfaces of the columns 10 along the arrangement direction, and a doorway 30 is formed between the vertical plate 20 and the two adjacent columns 10, and the shape of the doorway 30 is a quadrilateral. It can be understood that the doorway 30 is located below the vertical plate 20, and the oblique water flows through the flow-isolating wall structure from the doorway 30.

[0032] The doorway type flow-isolating wall structure includes columns 10 and vertical plates 20. There are multiple columns 10 and vertical plates 20. Multiple columns 10 are arranged along a straight line to form at least one row. Each vertical plate 20 is located at the upper part between two adjacent columns 10 and is detachably connected to two adjacent columns 10. The two side surfaces of the vertical plates 20 along the arrangement direction are flush with the two side surfaces of the columns 10 along the arrangement direction. A doorway 30 is formed between the vertical plates 20 and the two adjacent columns 10. The shape of the doorway 30 is a quadrilateral. In this way, multiple doorways 30 are formed in the flow-isolating wall structure. When oblique water flow acts on the doorway 30, the doorway 30 can effectively reduce the flow velocity of the oblique water flow, thereby reducing the lateral flow velocity in the gate area of ​​the pilot channel entrance, achieving a good diversion effect, thereby improving the water flow conditions in the gate area of ​​the pilot channel entrance, and ensuring that ships enter and exit the pilot channel safely and efficiently.

[0033] In this embodiment, the two side surfaces of the vertical plate 20 along the arrangement direction are flush with the two side surfaces of the columns 10 along the arrangement direction, which can also be understood as the thickness of the vertical plate 20 is the same as the thickness of the column 10, so that multiple columns 10 and vertical plates 20 form a straight wall structure.

[0034] In this embodiment, the vertical plate 20 and the column 10 are plug-fitted, that is, the vertical plate 20 is inserted into the upper part of the column 10. Figure 4 As shown, convex ribs 21 extending in the height direction are provided at both ends of the vertical plate 20, and slots 11 matching the convex ribs 21 are provided at the upper part of the column 10, and the convex ribs 21 are inserted into the slots 11 so that the vertical plate 20 is connected and fixed to the column 10. In the above arrangement, the convex ribs 21 are abutted against the bottom of the slots 11 in the height direction to achieve a limit stop. Of course, the slots 11 can also be provided at both ends of the vertical plate 20, and the convex ribs 21 can be provided on the inner side of the upper part of the column 10, which can be selected according to actual needs. It should be noted that in this arrangement, the convex ribs 21 on the column 10 need to have a certain distance from the top surface of the column 10, and accordingly, the slots 11 on the vertical plate 20 also need to have a certain distance from the top surface of the vertical plate 20, so that the convex ribs 21 abut against the top of the slots 11 to achieve a limit stop.

[0035] In this embodiment, the height of the slot 11 is the same as the height of the vertical plate 20. Specifically, since the ribs 21 extend along the height direction at both ends of the vertical plate 20, the height of the ribs 21 is the same as the height of the vertical plate 20, and the height of the slot 11 is the same as the height of the vertical plate 20, so that the height of the slot 11 is also the same as the height of the ribs 21, so that the ribs 21 and the slot 11 are more tightly and firmly plugged together.

[0036] In this embodiment, the cross section of the rib 21 is an inverted triangle. With the above arrangement, the rib 21 can be more tightly and firmly plugged into the slot 11. Of course, the cross section of the rib 21 can also be other shapes, which can be selected according to actual needs.

[0037] like Figure 5 As shown, in an optional embodiment, the shape of the doorway 30 is a rhombus. Specifically, the rhombus of the doorway 30 is inclined toward the downstream of the waterway. In other words, the flow direction of the water in the doorway 30 is roughly symmetrical with the oblique water flow relative to the flow barrier, that is, the oblique water flow turns when flowing through the doorway 30. By setting the shape of the doorway 30 to a rhombus, it is at a specific angle to the oblique water flow. The oblique water flow acts on the rhombus-shaped doorway 30, which can reduce the flow velocity of the oblique water flow on the one hand, and achieve the turning of the water flow angle on the other hand. The horizontal and vertical dimensions of the doorway 30 can be adjusted according to the water flow characteristics of different regions to better achieve the energy dissipation and diversion effects, thereby significantly reducing the lateral flow velocity in the gate area, which plays an important role in the safe and efficient entry and exit of ships in the pilot channel.

[0038] It can be understood that the shape of the door opening 30 is the same as the cross-sectional shape of the vertical plate 20. Furthermore, in order to form a diamond-shaped door opening 30, among the plurality of columns 10, the cross-sectional shapes of the columns 10 at both ends are right-angled trapezoids, and the cross-sectional shapes of the columns 10 in the middle are also diamond-shaped. Figure 5 shown.

[0039] In this embodiment, the angle and size of the door opening 30 need to be determined according to the direction and size of the oblique water flow, in order to adjust the lateral flow velocity to the flow velocity along the river.

[0040] In this embodiment, the flow partition wall structure is a single-row structure. In an optional embodiment, multiple columns 10 form multiple rows. The number of rows of columns 10 can be selected according to actual needs, so as to limit the lateral flow velocity in the entrance area to a suitable range. Furthermore, the spacing between two adjacent columns 10 in each row of columns 10 is different. Through the above arrangement, the lateral flow velocity in the entrance area can be further reduced, thereby ensuring that ships can enter and exit the pilot channel safely and efficiently.

[0041] In another alternative embodiment, Figure 6As shown, the height of the plurality of vertical plates 20 gradually increases in the direction toward the downstream of the channel. In other words, the height of the plurality of door openings 30 gradually decreases in the direction toward the downstream of the channel. Through the above arrangement, the lateral flow velocity in the gate area can be further reduced, thereby ensuring that ships enter and exit the pilot channel safely and efficiently.

[0042] In this embodiment, the column 10 is a prefabricated steel sheet pile structure or a prefabricated reinforced concrete structure. That is, the column 10 can be a finished product prefabricated in a factory, and then constructed on the water using ship machinery equipment, or constructed on the shore using a long-arm machine, thereby reducing construction procedures, reducing engineering construction difficulty and investment, and saving construction time.

[0043] In an optional embodiment, the column 10 is a composite structure, the lower part of the column 10 is a cast-in-place structure or a prefabricated structure, the upper part of the column 10 is a cast-in-place structure or a prefabricated structure, and the middle part of the column 10 is a cast-in-place structure. Specifically, the lower part of the column 10 is an underwater part, so it is necessary to adopt a cast-in-place structure or directly adopt a prefabricated structure, the middle part and the upper part of the column 10 can both adopt a cast-in-place structure, so as to be completed together through a cast-in-place process, or the upper part of the column 10 adopts a prefabricated structure, and the middle part of the column 10 adopts a cast-in-place structure, so that the upper part and the lower part can be connected and fixed.

[0044] From the above description, it can be seen that the above-mentioned embodiment of the utility model achieves the following technical effects: by setting a doorway type flow-isolating wall structure including columns 10 and upright plates 20, there are multiple columns 10 and upright plates 20, multiple columns 10 are arranged along a straight line to form at least one row, each upright plate 20 is located at the upper part between two adjacent columns 10, and is detachably connected to two adjacent columns 10 respectively, the two side surfaces of the upright plates 20 along the arrangement direction are flush with the two side surfaces of the columns 10 along the arrangement direction, and a doorway 30 is formed between the upright plates 20 and the two adjacent columns 10, and the shape of the doorway 30 is a quadrilateral, so that multiple doorways 30 are formed in the flow-isolating wall structure, when oblique water flow acts on the doorway 30, the doorway 30 can effectively reduce the flow velocity of the oblique water flow, thereby reducing the lateral flow velocity in the gate area of ​​the pilot channel entrance, playing a good diversion effect, and then improving the water flow conditions in the gate area of ​​the pilot channel entrance, ensuring that ships enter and exit the pilot channel safely and efficiently.
