Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, and in particular to a flow-isolating pier structure and a flow-isolating dam. 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 set up a dike between the hub and the ship lock approach channel. The dike 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 dikes 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 of poor diversion effect of the flow barrier. Utility Model Content

[0025] 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.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] In order to solve the problem of poor diversion effect of flow separation dikes in the prior art, the utility model provides a flow separation pier structure and a flow separation dike.

[0030] like Figure 3 to Figure 4 As shown, the flow-isolating pier structure includes a pier body 10, a connecting member 20 and an anchor pile 30. At least a portion of the pier body 10 floats on the water surface, the anchor pile 30 is installed and fixed on the bottom of the water, the connecting member 20 is connected to the pier body 10 and the anchor pile 30 respectively, and the pier body 10 is in the shape of a quadrilateral.

[0031] By setting up a flow-isolating pier structure including a pier body 10, a connecting piece 20 and an anchoring pile 30, at least a part of the pier body 10 floats on the water surface, the anchoring pile 30 is installed and fixed on the bottom of the water, the connecting piece 20 is connected to the pier body 10 and the anchoring pile 30 respectively, and the shape of the pier body 10 is a quadrilateral. In this way, a plurality of flow-isolating pier structures are set up in the waterway to form a flow-isolating dike, and a doorway is formed between two adjacent flow-isolating pier structures. The doorway is a quadrilateral, so that a plurality of doorways are formed in the flow-isolating dike. When oblique water flow acts on the doorway, the doorway 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.

[0032] like Figure 4 As shown, in an optional embodiment, the shape of the pier body 10 is a rhombus. Correspondingly, the shape of the doorway is a rhombus. Specifically, the rhombus of the pier body 10 is inclined toward the downstream of the waterway. Correspondingly, the rhombus of the doorway is inclined toward the downstream of the waterway. In other words, the flow direction of the water in the doorway 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. By setting the shape of the pier body 10 to a rhombus, the shape of the doorway is a rhombus, which is at a specific angle to the oblique water flow. The oblique water flow acts on the rhombus-shaped doorway, which can reduce the flow velocity of the oblique water flow on the one hand, and realize the turning of the water flow angle on the other hand. The horizontal and vertical dimensions of the doorway 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.

[0033] In this embodiment, the pier body 10 is made of a hollow composite plastic material with a low density, so it can float on the water.

[0034] In the present embodiment, there are multiple connectors 20 and anchor piles 30, and the multiple connectors 20 and the multiple anchor piles 30 are arranged one by one, and the multiple connectors 20 are at least connected to each corner of the pier body 10. Specifically, there are four connectors 20 and anchor piles 30, and the four connectors 20 are respectively connected to the four corners of the pier body 10. It can be understood that the arrangement shape of the four anchor piles 30 is a quadrilateral that matches the pier body 10. When the pier body 10 is a rhombus, the four anchor piles 30 are also arranged in a rhombus. Of course, the number of connectors 20 and anchor piles 30 can also be more, so that the connection between the pier body 10 and the anchor piles 30 is more secure, and it can be selected according to actual needs.

[0035] like Figure 3 to Figure 4 As shown, the bottom of the pier body 10 and the top of the anchor pile 30 are respectively provided with hanging ears 40, and both ends of the connector 20 are respectively connected to the hanging ears 40. It can be understood that the hanging ears 40 on the bottom of the pier body 10 and the top of the anchor pile 30 are respectively provided with the connector 20 in a one-to-one correspondence.

[0036] In this embodiment, the connecting member 20 is an anchor chain. By adopting the connection mode of the anchor chain, the pier body 10 and the anchor pile 30 are flexibly connected. When impacted by a strong water flow, a certain movement can occur to play a buffering role, thereby preventing the connecting member 20 from being broken and causing the flow-isolating pier structure to be unable to be used normally, thereby improving the service life of the flow-isolating pier structure.

[0037] In this embodiment, the top of the anchor pile 30 is exposed on the bottom of the water, so that the lug 40 thereon can be connected to the connector 20. Further, the anchor chain is made of metal, such as iron chain, stainless steel chain, etc. The anchor pile 30 is made of reinforced concrete or metal.

[0038] In this embodiment, due to the different positions, the hanging ears 40 on the pier body 10 and the hanging ears 40 on the anchor pile 30 are made of different materials. Specifically, the hanging ears 40 on the pier body 10 can be made of the same composite plastic material as the pier body 10. Further, the hanging ears 40 on the pier body 10 are integrally formed with the pier body 10 to improve the structural strength. The hanging ears 40 on the anchor pile 30 are made of metal and can be welded to the anchor pile 30 or fixed to the anchor pile 30 by threaded connection.

[0039] like Figure 5 As shown, the present application also provides a flow-isolating dike, including the above-mentioned flow-isolating pier structure. Specifically, there are multiple flow-isolating pier structures, and the multiple flow-isolating pier structures are arranged at intervals. In this way, a doorway is formed between two adjacent flow-isolating pier structures, and the oblique water flows through the flow-isolating dike from the doorway. Since the two adjacent flow-isolating pier structures are both quadrilaterals, the doorway formed thereby is also a quadrilateral, thereby forming multiple doorways in the flow-isolating dike. When the oblique water flow acts on the doorway, the doorway can effectively reduce the flow velocity of the oblique water flow, thereby reducing the lateral flow velocity in the pilot channel entrance area, achieving a good diversion effect, thereby improving the water flow conditions in the pilot channel entrance area, and ensuring that ships enter and exit the pilot channel safely and efficiently.

[0040] Furthermore, a plurality of flow isolation pier structures are arranged at intervals along a straight line to form one or more rows.

[0041] In this embodiment, the flow-isolating dike is a single-row structure. In an optional embodiment, multiple flow-isolating pier structures form multiple rows. The number of rows of flow-isolating pier structures 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 flow-isolating pier structures in each row of flow-isolating pier structures is different. Through the above-mentioned 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.

[0042] From the above description, it can be seen that the above-mentioned embodiments of the utility model achieve the following technical effects: by setting a flow-isolating pier structure including a pier body 10, a connecting piece 20 and an anchoring pile 30, at least a part of the pier body 10 floats on the water surface, the anchoring pile 30 is installed and fixed on the bottom of the water, the connecting piece 20 is respectively connected to the pier body 10 and the anchoring pile 30, and the shape of the pier body 10 is a quadrilateral, so that a plurality of flow-isolating pier structures are set in the waterway to form a flow-isolating dike, and a doorway is formed between two adjacent flow-isolating pier structures, and the doorway is a quadrilateral, thereby forming a plurality of doorways in the flow-isolating dike, when the oblique water flow acts on the doorway, the doorway 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, and ensuring that ships enter and exit the pilot channel safely and efficiently.
