Description

Technical Field

[0001] This application relates to the field of water conservancy engineering technology, specifically to a central pier structure. Background Technology

[0002] A gate slot is a structural component used to install and guide a gate. It is typically a groove or frame and is used in water conservancy projects, pumping stations, canals, and other similar facilities. The main function of the gate slot is to provide a stable installation position for the gate and ensure smooth movement during opening and closing.

[0003] In existing multi-hole sluice gates, gate slots are required on both sides of the central pier. This design occupies a significant amount of space on the central pier, increasing its overall thickness. Furthermore, the gate slots are susceptible to corrosion from water flow and sediment, exhibiting poor durability and lacking the ability to self-repair. Severe corrosion of the gate slots can render them unusable and complicate maintenance.

[0004] Therefore, the structure of the gate slot in the prior art has room for further improvement. Utility Model Content

[0005] In view of this, and in response to the technical problems in the prior art where the gate slot occupies a large space of the central pier, resulting in an increase in the overall thickness of the central pier and the gate slot being susceptible to corrosion by water flow and silt, this application provides a central pier structure. By changing the structure of the central pier, the overall width of the gate slot is made the same as the width of the central pier, which can effectively reduce the thickness of the central pier, thereby reducing the width of the sluice gate bottom plate. After comprehensive optimization, the amount of reinforced concrete used is reduced, saving materials and costs.

[0006] To achieve the above objectives, this application provides the following technical solution: a mid-pier structure, comprising:

[0007] The gate slots of the central pier are arranged on both sides of the central pier, and the gate is located between the gate slots of the central pier and the side piers.

[0008] The gate slot of the middle pier includes a support component and a connecting component; one side of the connecting component is connected to the support component and the other side is connected to the middle pier, and the connecting component is located between the support component and the middle pier.

[0009] The connecting component is fixedly connected to the supporting component;

[0010] or,

[0011] The connecting component is detachably connected to the supporting component.

[0012] Compared with existing technologies, the gate slot of this application features a support assembly and a connecting assembly. The support assembly supports the gate, and the connecting assembly connects the support assembly to the central pier to form an integral structure, thereby enhancing the stability of the gate. Furthermore, the width of the support assembly is the same as the width of the central pier, which reduces the thickness of the central pier and the amount of reinforced concrete used. The detachable connection between the support assembly and the connecting assembly allows for easy disassembly and installation of the gate slot when maintenance or component replacement is required. After disposal, it can be 100% disassembled, reducing waste and aligning with the concept of sustainable development. It is also convenient to operate and saves materials and costs.

[0013] Preferably, the support component is provided with a connector, and the connection component is provided with a mating component, which mates with the connector to achieve a detachable connection between the support component and the connection component;

[0014] The connecting component is configured as a protrusion, and the mating component is configured as a mounting groove;

[0015] or,

[0016] The connector is configured as a mounting groove, and the mating part is configured as a protrusion.

[0017] In this embodiment, the protrusion of the connector can effectively combine with the mounting groove of the mating part to form a firm connection, thereby enhancing the stability between the support component and the connecting component. Furthermore, the size of the connector is adapted to the size of the mating part, ensuring precise alignment during connection and reducing operational difficulty.

[0018] Preferably, the connector has a first groove, and the mating part has a second groove. The first groove is recessed in the direction away from the central support, and the second groove protrudes in the direction away from the connector. The diameter of the second groove is the same as the diameter of the first groove.

[0019] After the mating parts and the connecting parts are connected, the second groove and the first groove form a seepage-proof hole.

[0020] In this embodiment, the seepage-proof hole is naturally formed after the mating parts and connectors are combined. It is used for emergency seepage prevention. As a secondary water-stopping guarantee, the seepage-proof hole may not be needed under normal circumstances, but it can play a role when problems occur. The existence of the seepage-proof hole is to provide additional water-tight protection.

[0021] Preferably, the middle pier is provided with a guide groove, and the connecting component is provided with a positioning element. One end of the positioning element is connected to the support component, and the other end of the positioning element is connected to the guide groove, so as to fix the middle pier and the connecting component.

[0022] There are at least two guide grooves, with adjacent guide grooves spaced apart, and the size of the guide grooves is adapted to the size of the positioning component.

[0023] In this embodiment, the guide groove can provide guidance for the connecting components, so that the positioning component can be accurately connected to the guide groove, avoiding damage caused by connection deviation, thereby enhancing the stability of the gate slot of the central pier and the overall structure of the central pier, and extending its service life.

[0024] Preferably, the support assembly includes a fixing member and parallel support members, with both ends of the fixing member connected to the two support members respectively, the fixing member being located in the middle of the support members, and the support members being located between the connecting assembly and the fixing member;

[0025] In the horizontal direction, the width of the support member is L1, and the width of the middle pier is L2;

[0026] L1 = L2.

[0027] In this embodiment, the width of the support member is equal to the width of the central pier, which can effectively reduce the thickness of the central pier, thereby reducing the width of the sluice gate bottom plate. After comprehensive optimization, the amount of reinforced concrete used is reduced, saving construction materials and costs.

[0028] Preferably, the support assembly further includes multiple support plates, which are connected to the support member, and the fixing member is located between two support plates;

[0029] The end of the support plate furthest from the fixing member is flush with the end of the support member.

[0030] In this embodiment, the end of the support plate away from the fixing member is flush with the end of the support member, which can reduce the amount of reinforced concrete used in the gate pier. When the gate is opened or closed, the support plate contacts the gate. The support plate can replace the support member in contacting the gate, thereby reducing the wear caused by friction between the gate and the support member and extending the service life of the support assembly.

[0031] Preferably, the fastener includes a first steel plate and two parallel second steel plates, with both ends of the first steel plate connected to the two second steel plates respectively, and both ends of the second steel plates connected to the support member respectively;

[0032] The first steel plate is arranged parallel to the support member.

[0033] In this embodiment, by setting a first steel plate and a second steel plate, the load of the gate can be better transferred to the first steel plate and the second steel plate, ensuring that the fixing component will not be excessively deformed or fail when under stress, thereby better supporting the gate.

[0034] Preferably, the fixing member has a cavity located between the first steel plate and the support member, and the cavity is filled with an empty box.

[0035] The empty box is filled with magnetorheological fluid.

[0036] In this embodiment, the empty box is filled with magnetorheological fluid. When it encounters an earthquake or ice impact, the viscosity of the fluid can be changed instantly by the electromagnetic field, thereby reducing the impact load and protecting the gate slot and its structure.

[0037] Preferably, the connecting component includes a guide and a plurality of connecting ribs, wherein the end of the guide away from the support component is connected to the connecting ribs, and the connecting ribs extend in a direction away from the support component;

[0038] The guide component has a filling section located between two adjacent mating components, and the filling section is filled with an empty box.

[0039] In this embodiment, filling the filling interval with empty boxes can reduce the amount of concrete used, reduce the overall self-weight of the central pier, and save costs without affecting the strength of the connecting components.

[0040] Preferably, there is a gap between the mating part and the connecting part, the gap being 3 to 5 mm, and the gap is filled with highly elastic silicone material.

[0041] In this embodiment, by reserving a width of 3-5 mm, the changes caused by thermal expansion and contraction of the high-elasticity silicone material can be effectively addressed. The high-elasticity silicone material is a material with good elasticity and elongation, which can maintain its shape and performance when stretched or compressed. The elongation of the high-elasticity silicone material is ≥300%, which means that the high-elasticity silicone material can stretch to a large extent without breaking, thereby preventing damage or deformation of the high-elasticity silicone material due to excessive force, improving the stability of the overall structure, and extending its service life.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.

[0058] The present application will now be described in further detail with reference to the accompanying drawings, see below. Figures 1 to 6 illustrate.

[0059] Example 1

[0060] This embodiment provides a type of pier structure, which is applied in the field of hydraulic engineering technology. Specifically, as shown in... Figures 1 to 6As shown, the gate includes a central pier gate slot 1, which is located on both sides of the central pier. The gate is situated between the central pier gate slot 1 and the side piers. The central pier gate slot 1 includes a support assembly 11 and a connecting assembly 12. The support assembly 11 is located between two adjacent gates and is used to support the gate, ensuring its stability and safety during opening and closing. One side of the connecting assembly 12 is connected to the support assembly 11, and the other side of the connecting assembly 12 is connected to the central pier. The connecting assembly 12 is located between the support assembly 11 and the central pier, on the side of the support assembly 11 furthest from the gate. The connecting assembly 12 connects the support assembly 11 and the central pier to form an integral structure, thereby enhancing the stability of the gate. The connecting component 12 and the supporting component 11 are detachably connected. This detachable connection provides flexibility to the gate slot 1 of the middle pier, making it easy to adjust or replace during construction and maintenance. When the supporting component 11 is damaged after long-term use, it can be easily disassembled and replaced, reducing the disassembly of the overall structure. After being scrapped, it can be 100% disassembled, reducing waste and conforming to the concept of sustainable development. It is easy to operate and saves materials and costs.

[0061] The support component 11 is equipped with a connector 111, and the connecting component 12 is equipped with a mating component 121. The mating component 121 mates with the connector 111 to achieve a detachable connection between the support component 11 and the connecting component 12. This allows for easy disassembly and installation of the gate slot when maintenance or component replacement is required. After being scrapped, it can be 100% disassembled, reducing waste and conforming to the concept of sustainable development. It is also convenient to operate and saves materials and costs. Furthermore, the width of the support component 11 is the same as the width of the central pier, which reduces the thickness of the central pier and thus reduces the load on the sluice gate bottom plate. This, in turn, reduces the width of the sluice gate bottom plate. Overall optimization reduces the amount of reinforced concrete used, saving materials and costs.

[0062] Specifically, such as Figure 3 As shown, the connector 111 is configured as a protrusion 3, and the mating part 121 is configured as a mounting groove. There are multiple connectors 111 and multiple mating parts 121, with each connector 111 corresponding to a single mating part 121. The dimensions of the connector 111 and the mating part 121 are matched. The protrusion 3 of the connector 111 can effectively combine with the mounting groove of the mating part 121 to form a firm connection, thereby enhancing the stability between the support assembly 11 and the connecting assembly 12. Furthermore, the matching dimensions of the connector 111 and the mating part 121 ensure precise alignment during connection and reduce operational difficulty. The diameter of the connector 111 gradually increases from the bottom towards the mating part 121, and the two sides of the connector 111 are inclined away from the center of the support assembly 11, which can increase the contact area of ​​the connection, further enhance the firmness of the connection, and also help to disperse stress under load and reduce local stress concentration.

[0063] It should be noted that the connector 111 can also be set as a mounting groove, and the mating part 121 can be set as a protrusion 3.

[0064] The mating part 121 has a second groove 1211, and the connecting part 111 has a first groove 1111. The second groove 1211 protrudes away from the connecting part 111, and its protruding surface is an arc surface. The first groove 1111 is recessed away from the central support, and its recessed surface is an arc surface. The diameter of the second groove 1211 is the same as the diameter of the first groove 1111. After the mating part 121 and the connecting part 111 are connected, the second groove 1211 and the first groove 1111 form a seepage-proof hole 4. This means that the seepage-proof hole 4 is naturally formed after the mating part 121 and the connecting part 111 are combined. It is a seepage-proof hole 4 used for emergency purposes. The seepage-proof hole 4 serves as a secondary water-stopping guarantee, meaning that it may not be needed under normal circumstances, but it can play a role when problems occur. The existence of the seepage-proof hole 4 is to provide additional water-tight protection.

[0065] Furthermore, such as Figure 3 As shown, the support assembly 11 includes a fixing member 112 and parallel support members 113. The two ends of the fixing member 112 are respectively connected to the support members 113. The fixing member 112 is located in the middle of the support members 113. The support members 113 are located between the connecting member 111 and the fixing member 112. That is, the two ends of the fixing member 112 are perpendicularly connected to the two support members 113 respectively. The connection angle between the fixing member 112 and the support members 113 is 90°. The fixing member 112 can evenly transfer the load to the support members 113, ensuring that the support members 113 will not deform excessively or fail when under stress. From the horizontal direction, the support members 113 and the fixing member 112 are connected to form an H-shaped structure. The H-shaped structure can provide good stability, effectively distribute and bear the weight from the gate and the pressure of the water flow, enhance the bending and shear resistance of the overall structure, and effectively reduce the amount of reinforced concrete used, thus reducing the cost. In the horizontal direction, the width of the support member 113 is L1, and the width of the middle pier is L2. L1 = L2, which can effectively reduce the thickness of the middle pier, thereby reducing the width of the sluice gate bottom plate. After comprehensive optimization, the amount of reinforced concrete used is reduced, saving materials and costs.

[0066] Furthermore, such as Figure 3As shown, the support assembly 11 also includes multiple support plates 114. The support plates 114 are made of alloy material, but in this embodiment, steel material can be used. The support plates 114 are connected to the support member 113. The fixing member 112 is located between two support plates 114, which means that each support member 113 is provided with two support plates 114. The support plates 114 are located on the side of the support member 113 away from the connecting plate. The end of the support plate 114 away from the fixing member 112 is flush with the end of the support member 113, which can reduce the amount of reinforced concrete used in the gate pier. When the gate is opened or closed, the support plate 114 contacts the gate. The support plate 114 can replace the support member 113 in contacting the gate, thereby reducing the wear caused by friction between the gate and the support member 113 and extending the service life of the support assembly 11.

[0067] Furthermore, the fixing member 112 includes a first steel plate 1121 and two parallel second steel plates 1122. The two ends of the first steel plate 1121 are perpendicularly connected to the second steel plates 1122, that is, the connection angle between the first steel plate 1121 and the second steel plate 1122 is 90°. The two ends of the second steel plate 1122 are perpendicularly connected to the support member 113, that is, the connection angle between the second steel plate 1122 and the support member 113 is 90°. In the horizontal direction, the first steel plate 1121 is parallel to the support member 113, and the second steel plate 1122 is parallel to the mating member 121. This allows the load of the gate to be better transferred to the first steel plate 1121 and the second steel plate 1122, ensuring that the fixing member 112 will not be excessively deformed or fail when under stress, thereby better supporting the gate. The first steel plate 1121 and the second steel plate 1122 are coated with an epoxy coating. The first steel plate 1121 and the second steel plate 1122 are sprayed with an epoxy coating containing microcapsules. After long-term friction with the gate, wear occurs. When the epoxy coating wears and cracks, it releases nano-silica particles to automatically fill the defects and improve the durability of the gate slot.

[0068] Furthermore, such as Figure 3 As shown, the fixing member 112 has a cavity 1123 located between the first steel plate 1121 and the support member 113. The cavity 1123 is filled with an empty box, which can reduce the amount of concrete used and the overall self-weight of the pier without affecting the strength of the support component 11, thus saving costs. The empty box is filled with magnetorheological fluid. When it encounters an earthquake or ice impact, the viscosity of the fluid can be instantly changed by an electromagnetic field, thereby reducing the impact load and protecting the gate slot and its structure.

[0069] Furthermore, such as Figure 3As shown, the connecting component 12 includes a guide 122 and multiple connecting ribs 123. The end of the guide 122 away from the support component 11 is connected to the connecting ribs 123. The multiple connecting ribs 123 are spaced apart, and the connecting ribs 123 are correspondingly arranged with the mating components 121. The connecting ribs 123 extend away from the support component 11 and are inserted into the middle pier, thereby enhancing the connection strength between the middle pier and the connecting component 12. The guide 122 has a filling section 1221 located between two adjacent mating components 121. The bottom of the filling section 1221 is aligned with the bottom of the mating component 121, and the top of the filling section 1221 is aligned with the top of the mating component 121. This allows the load borne by the mating component 121 to be evenly transferred to the filling section 1221. The filling section 1221 is filled with empty boxes, which reduces the amount of concrete used and the overall weight of the middle pier without affecting the strength of the connecting component 12, thus saving costs.

[0070] It should be noted that other materials can also be used to fill the 1221 area.

[0071] Furthermore, a gap of 3-5 mm is provided between the mating part 121 and the connecting part 111. The gap is filled with high-elasticity silicone material. This gap is an expansion joint with a width of 3-5 mm. The gap is designed to allow the material to expand or contract freely when the temperature changes. By reserving a width of 3-5 mm, the changes caused by thermal expansion and contraction of the high-elasticity silicone material can be effectively accommodated. High-elasticity silicone material is a material with good elasticity and elongation. It can maintain its shape and performance when stretched or compressed. The elongation of high-elasticity silicone material is ≥300%, which means that the high-elasticity silicone material can stretch to a large extent without breaking. This prevents the high-elasticity silicone material from being damaged or deformed due to excessive force, improves the stability of the overall structure, and extends its service life.

[0072] Example 2

[0073] The difference between this embodiment and Embodiment 1 is that, Figures 4 to 6As shown, in this embodiment, the connecting component 12 is fixedly connected to the supporting component 11. This fixed connection allows the connecting component 12 and the supporting component 11 to form an integral structure, which can better share and transmit the load from the gate, thereby enhancing the stability of the overall structure. It can also help reduce the gap between the connecting component 12 and the supporting component 11, thereby reducing the risk of leakage, reducing leakage repair costs, and extending the service life of the gate slot 1. The outer layer of the connecting component 12 is made of high-strength stainless steel, which can protect the connecting component 12 from damage and withstand the impact and pressure of the gate. The middle layer of the connecting component 12 is made of basalt fiber reinforced material. When the gate slot 1 is subjected to impact or vibration, the basalt fiber reinforced material can absorb and disperse energy, reduce damage to the gate slot 1, and improve the overall impact resistance of the gate slot 1. The inner layer of the connecting component 12 is made of self-healing coating, which can automatically repair when there are micro-cracks or damage on the coating surface, preventing crack propagation, thereby improving the durability of the connecting component 12 and extending the service life of the gate slot 1.

[0074] Example 3

[0075] The difference between this embodiment and Embodiment 1 is that, in this embodiment, as... Figures 4 to 6 As shown, the middle pier is provided with a guide groove 2, and the connecting component 12 is provided with a positioning element 124. The positioning element 124 is a protrusion. One end of the positioning element 124 is connected to the support component 11, and the other end of the positioning element 124 is connected to the guide groove 2 to fix the middle pier and the connecting component 12. The end of the positioning element 124 near the support component 11 is fixedly connected to the support component 11, and the other end of the positioning element 124 extends away from the support component 11 and is inserted into the guide groove 2, thereby realizing the fixed connection between the middle pier and the connecting component 12 and enhancing the connection strength between the middle pier and the connecting component 12. There are at least two guide grooves 2, and two adjacent guide grooves 2 are spaced apart. The size of the guide groove 2 is adapted to the size of the positioning element 124. The guide groove 2 can provide guidance for the connecting component 12, so that the positioning element 124 can be accurately connected to the guide groove 2, avoiding damage caused by connection deviation, thereby enhancing the stability of the middle pier gate slot 1 and the overall structure of the middle pier and extending its service life.

[0076] The connecting component 12 also includes multiple load-bearing components 125. Each load-bearing component 125 is made of steel plate. One end of the load-bearing component 125 is fixedly connected to the support component 11, and the other end of the load-bearing component 125 extends away from the gate. In the vertical direction, the multiple load-bearing components 125 are spaced apart. In the horizontal direction, the two sides of the load-bearing components 125 are flush with the two sides of the middle pier. The load-bearing components 125 are used to bear the load of the gate and transfer the load to the middle pier, thereby enhancing the strength of the gate slot of the middle pier.

[0077] Furthermore, such as Figure 4 As shown, at least two protrusions 3 are provided on the middle pier. The protrusions 3 are dovetail tenon-shaped structures. The protrusions 3 protrude towards the gate slot 1 of the middle pier. Two adjacent protrusions 3 are spaced apart. The guide groove 2 is located on the protrusions 3. The positioning component 124 is connected to the middle pier through the guide groove 2. When the positioning component 124 of the connecting component 12 is connected to the guide groove 2, the concrete is poured to fix the connecting component 12 to the middle pier. The outer side of the middle pier is provided with anti-seepage holes 4, that is, the side of the middle pier facing the connecting component 12 is provided with multiple anti-seepage holes 4. The end of the protrusion 3 is also provided with anti-seepage holes 4, that is, the end of the protrusion 3 near the connecting component 12 is provided with multiple anti-seepage holes 4. The anti-seepage holes 4 are reserved in advance during the construction process to reduce the risk of leakage between the new and old concrete interface. They can fill the gap between the new and old concrete, strengthen the interface, and reduce the possibility of water penetration.
