Description

Technical Field

[0001] The present application relates to the technical field of water conservancy engineering, and in particular to a door slot structure and a construction method. Background Art

[0002] A gate channel is a structural component, typically a groove or frame, used to mount and guide a gate. It's used in water conservancy projects, pumping stations, canals, and other facilities. The primary function of a gate channel is to provide a stable mounting location for the gate and ensure smooth movement during opening and closing.

[0003] Existing porous sluice gates require gate slots on both sides of the central pier. These slots are typically made of concrete, which takes up a significant amount of space in the central pier and increases its overall thickness. Furthermore, the slots are susceptible to corrosion from water flow and sediment, resulting in poor durability and the inability to self-repair. Severe corrosion can render the slots inoperable and make maintenance difficult. Repairs require the entire slot to be removed, and a new one to be installed and cast. This process can easily damage the central pier structure, making installation and removal very difficult.

[0004] In terms of construction, the gate slot adopts a two-phase concrete pouring method. The first phase of concrete needs to reserve dowel bars so that it can be welded with the gate slot later before the second phase of pouring. This construction process is relatively complicated, with many steps and a long construction period. At the same time, there are certain difficulties in controlling the installation accuracy.

[0005] Therefore, the structure of the gate slot in the prior art has room for further improvement. Summary of the Invention

[0006] The purpose of this application is to provide a gate slot structure and construction method to solve the problems mentioned in the background art that the gate slot easily leads to an increase in the overall thickness of the gate pier, is difficult to inspect and disassemble, has a complex construction process, and takes a long time to complete.

[0007] To achieve the above objectives, the present application provides a door slot structure, comprising:

[0008] At least one middle pier, wherein the middle pier is provided with a middle pier gate slot, and the middle pier gate slot is arranged on both sides of the middle pier;

[0009] At least two side piers, the middle pier is located between the two side piers, and the side pier gate slots are provided on the side facing the middle pier;

[0010] The middle pier gate slot includes a connecting assembly and a supporting assembly; one side of the connecting assembly is connected to the supporting assembly and the other side is connected to the middle pier, and both ends of the gate are connected to the supporting assembly and the side pier gate slot respectively, and the supporting assembly and the side pier gate slot are correspondingly arranged;

[0011] Wherein, the connecting assembly is fixedly connected to the supporting assembly;

[0012] or,

[0013] The connecting assembly is detachably connected to the supporting assembly.

[0014] Compared to the prior art, the gate slot structure of the present application features a connecting assembly and a supporting assembly. The fixed or detachable connection between the connecting assembly and the supporting assembly provides flexibility for the middle pier gate slot, facilitating adjustment or replacement during construction and maintenance. When the connecting assembly and the supporting assembly are fixedly connected, they form a single, integrated structure, effectively sharing and transmitting the load from the gate, thereby enhancing the stability of the overall structure. This also helps reduce gaps between the connecting assembly and the supporting assembly, thereby reducing the risk of leakage and lowering the cost of repairs. When the connecting assembly and the supporting assembly are detachably connected, the supporting assembly can be easily removed and replaced if damaged over time, reducing the need for disassembly of the entire structure. Upon scrapping, the structure can be 100% disassembled, reducing waste, aligning with the concept of sustainable development, and offering ease of operation and saving construction materials and costs. This design can extend the service life of the middle pier gate slot, reduce the overall thickness of the gate pier, facilitate maintenance and assembly and disassembly, and simplify the construction process, resulting in a streamlined process and a shorter construction period.

After scrapping, it can be 100% disassembled, reducing waste, complying with the concept of sustainable development, easy to operate, and saving construction materials and costs.

[0022] Wherein, in the horizontal direction, the width of the support plate is L1, and the width of the middle pier is L2;

[0023] L1=L2.

[0024] In this embodiment, the width of the support plate is equal to the width of the middle pier, which can effectively reduce the thickness of the middle pier, thereby reducing the width of the sluice bottom plate. After comprehensive optimization, the amount of reinforced concrete used is reduced, saving construction materials and costs.

[0025] Preferably, the fixing member includes a first steel plate and two second steel plates arranged in parallel, the two ends of the first steel plate are respectively connected to the two second steel plates, and the two ends of the second steel plate are respectively connected to the two support plates;

[0026] The first steel plate is arranged parallel to the support plate.

[0027] In this embodiment, by providing the first steel plate and the 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 parts will not be excessively deformed or fail when subjected to force, thereby better supporting the gate.

[0028] Preferably, a cavity is provided in the fixing member, the cavity is located between the first steel plate and the support plate, and the cavity is filled with an empty box;

[0029] Wherein, the empty box is filled with magnetorheological fluid.

[0030] In this embodiment, the empty box is filled with magnetorheological fluid. When encountering an earthquake or ice impact, the electromagnetic field can instantly change the viscosity of the fluid, thereby reducing the impact load and protecting the middle pier gate slot and its structure.

Therefore, the above terms cannot be understood as limiting this application.

[0063] The present application will be described in further detail below with reference to the accompanying drawings. Figures 1 to 8 illustrate.

[0064] Example 1

[0065] This embodiment provides a door slot structure and construction method, which are used in the field of water conservancy engineering technology, such as Figures 1 to 8As shown, this embodiment provides a door slot structure, which is used in the field of water conservancy engineering technology, such as Figures 1 to 6 As shown, it includes at least one middle pier 3 and at least two side piers 4. The middle pier 3 is provided with a middle pier gate groove 1, and the middle pier gate groove 1 is arranged on both sides of the middle pier 3; the middle pier 3 is located between the two side piers 4, and the side piers 4 are provided with a side pier gate groove 2, which is arranged on the side facing the middle pier 3. The gate is located between the side piers 4 and the middle pier 3. The middle pier gate groove 1 and the side pier gate groove 2 jointly support the gate to ensure the stability and safety of the gate during the opening and closing process, thereby enhancing the stability of the gate.

[0066] Among them, the middle pier gate slot 1 includes a connecting component 11 and a supporting component 12. One side of the connecting component 11 is connected to the supporting component 12, and the other side of the connecting component 11 is fixedly connected to the middle pier 3. The two ends of the gate are respectively connected to the supporting component 12 and the side pier gate slot 2. The supporting component 12 is arranged corresponding to the side pier gate slot 2. The connecting component 11, the supporting component 12 and the side pier gate slot 2 form a stable support system, which can effectively support the two ends of the gate and ensure its stability during the opening and closing process.

[0067] like Figure 3 As shown, the connecting assembly 11 is fixedly connected to the supporting assembly 12. The fixed connection enables the connecting assembly 11 and the supporting assembly 12 to form an integral structure, which can better share and transfer the load from the gate, thereby enhancing the stability of the overall structure. It can also help to reduce the gap between the connecting assembly 11 and the supporting assembly 12, thereby reducing the risk of leakage, reducing the leakage repair cost, and extending the service life of the middle pier gate slot 1.

[0068] Further, such as Figures 2 to 4When the cam 112 is in the unlocking state, the cam 112 is locked and the locking cam 112 is locked. Among them, the connecting component 11 also includes multiple load-bearing members 115, which are set as steel plates. One end of the load-bearing member 115 is fixedly connected to the support component 12, and the other end of the load-bearing member 115 extends in the direction away from the gate. From the vertical direction, multiple load-bearing members 115 are arranged at intervals. From the horizontal direction, the two sides of the load-bearing member 115 along the horizontal direction are flush with the two sides of the middle pier 3. The load-bearing member 115 is used to bear the load of the gate and transfer the load to the middle pier 3, thereby enhancing the strength of the middle pier gate slot 3.

[0069] Further, such as Figure 3 As shown, the support assembly 12 includes a fixing member 122 and two parallel support plates 123, the two ends of the fixing member 122 are respectively connected to the two support plates 123, the fixing member 122 is located in the middle of the support plates 123, and the support plates 123 are located between the connecting assembly 11 and the fixing member 122, that is, the two ends of the fixing member 122 are respectively connected to the two support plates 123 vertically, that is, the connection angle between the fixing member 122 and the support plates 123 is 90°, and the fixing member 122 can evenly transfer the load to the support plates 123, ensuring that the support plates 123 will not be excessively deformed or fail when subjected to force. From the horizontal direction, the support plates 123 are connected to the fixing member 122 to form an H-shaped structure. The H-shaped structure can provide good stability, can effectively disperse and withstand the weight of the gate and the pressure of the water flow, enhance the bending and shear resistance of the overall structure, and at the same time can effectively reduce the use of reinforced concrete and reduce the construction cost. Among them, in the horizontal direction, the width of the support plate 123 is L1, the width of the middle pier 3 is L2, L1=L2, which can effectively reduce the thickness of the middle pier 3, thereby reducing the width of the sluice bottom plate. After comprehensive optimization, the amount of reinforced concrete used is reduced, saving materials and costs.

[0070] Further, such as Figure 3As shown, the fixing member 122 includes a first steel plate 1221 and two second steel plates 1222 arranged in parallel. The two ends of the first steel plate 1221 are respectively connected vertically to the two second steel plates 1222, that is, the connection angle between the first steel plate 1221 and the second steel plate 1222 is 90°, and the two ends of the second steel plate 1222 are respectively connected vertically to the two support plates 123, that is, the connection angle between the second steel plate 1222 and the support plate 123 is 90°. Viewed in the horizontal direction, the first steel plate 1221 is parallel to the support plate 123, and the second steel plate 1222 is parallel to the matching portion 111. By arranging the first steel plate 1221 and the second steel plate 1222, the load of the gate can be better transferred to the first steel plate 1221 and the second steel plate 1222, ensuring that the fixing member 122 will not be excessively deformed or fail when subjected to force, thereby better supporting the gate. Among them, the surfaces of the first steel plate 1221 and the second steel plate 1222 are provided with an epoxy coating. The surfaces of the first steel plate 1221 and the second steel plate 1222 are sprayed with an epoxy coating containing microcapsules. After long-term friction with the gate, wear will occur. When the epoxy coating is worn and cracked, it will release nano-silicon dioxide particles to automatically fill the defects, thereby improving the durability of the middle pier gate slot 1.

[0071] Further, such as Figure 3 As shown, the support assembly 12 also includes a plurality of protective plates 124. The protective plates 124 are made of alloy material. In this embodiment, steel material can be used. The protective plates 124 are connected to the support plates 123. The second steel plate 1222 is located between the two protective plates 124, which means that each support plate 123 is provided with two protective plates 124, and the protective plates 124 are arranged on the side of the support plate 123 away from the connecting assembly 11. The end of the protective plate 124 away from the fixing member 122 is flush with the end of the support plate 123, which can reduce the amount of reinforced concrete used in the gate pier. When the gate is opened or closed, the protective plate 124 contacts the gate. The protective plate 124 can replace the support plate 123 to contact the gate, thereby reducing the wear caused by friction between the gate and the support plate 123, and extending the service life of the middle pier gate slot 1.

[0072] Further, such as Figure 3 As shown, a cavity 1223 is defined within the fixture 122, located between the first steel plate 1221 and the support plate 123. This cavity 1223 is filled with a hollow box, which reduces the amount of concrete used and the overall weight of the middle pier 3, thereby saving construction costs, without compromising the strength of the fixture 122. The hollow box is filled with magnetorheological fluid, which, when impacted by earthquakes or ice, instantly changes the fluid's viscosity through electromagnetic fields, reducing the impact load and thus protecting the middle pier gate slot 1 and its structure.

[0073] Further, such as Figure 3As shown, the connecting component 11 also includes a plurality of connecting ribs 113, which are arranged at intervals, and the connecting ribs 113 are arranged corresponding to the matching parts 111. The connecting ribs 113 extend in a direction away from the supporting component 12 and are inserted into the middle pier 3, thereby enhancing the connection strength between the middle pier 3 and the connecting component 11.

[0074] Further, such as Figures 2 to 4 As shown, at least two protrusions 32 are provided on the middle pier 3, and the protrusions 32 are dovetail tenon type structures. The protrusions 32 protrude toward the middle pier gate slot 1, and the two adjacent protrusions 32 are arranged at intervals. The guide groove 31 is located on the protrusion 32, and the positioning member 112 is connected to the middle pier 3 through the guide groove 31. When the positioning member 112 of the connecting assembly 11 is connected to the guide groove 31, the concrete is poured to fix the connecting assembly 11 and the middle pier 3. The dovetail tenon type structure has good pull-out resistance and can enhance the strength between the middle pier 3 and the connecting assembly 11, so that the middle pier 3 and the connecting assembly 11 can withstand greater tension and shear force. Among them, anti-seepage holes 33 are provided on the outer side of the middle pier 3, that is, a plurality of anti-seepage holes 33 are provided on the side of the middle pier 3 facing the connecting component 11, and anti-seepage holes 33 are also provided on the end of the protrusion 32, that is, a plurality of anti-seepage holes 33 are provided on the end of the protrusion 32 close to the connecting component 11. The anti-seepage holes 33 are reserved in advance during the construction process to reduce the risk of leakage between the new and old concrete bonding surfaces, fill the gaps between the new and old concrete, strengthen the bonding surface, and reduce the possibility of moisture penetration.

[0075] Further, such as Figures 5 and 6 As shown, the side pier gate slot 2 includes a support member 21 and a slot body 22. The slot body 22 is fixedly connected to the side pier 4 and movably connected to the support member 21. The slot body 22 at least partially cooperates with the support member 21 to achieve the connection between the slot body 22 and the support member 21. The cooperation between the slot body 22 and the support member 21 ensures an effective connection between the two, enhancing the stability and reliability of the overall structure of the side pier gate slot 2. The width of the side pier gate slot 2 is the same as the width of the side pier 4. That is, the end of the support member 21 away from the slot body 22 is in a straight line with the outer edge of the side pier 4. This can reduce the thickness of the side pier 4, thereby reducing the load on the sluice bottom plate of the side pier 4, thereby reducing the width of the sluice bottom plate. After comprehensive optimization, the amount of reinforced concrete is reduced, saving materials and costs.

[0076] Further, such as Figure 6As shown, the support member 21 includes a first reinforcing plate 211 and two second reinforcing plates 212 arranged in parallel. The two ends of the first reinforcing plate 211 are respectively vertically connected to the ends of the two second reinforcing plates 212, and the other end of the second reinforcing plate 212 extends toward the direction 22 away from the groove body, that is, the connection angle between the first reinforcing plate 211 and the second reinforcing plate 212 is 90°. The first reinforcing plate 211 and the two second reinforcing plates 212 are connected and combined to form a groove, thereby improving the support for the gate.

[0077] Among them, at least two first protrusions 2111 are provided on the first reinforcing plate 211, and at least one second protrusion 2121 is provided on the second reinforcing plate 212. The first protrusion 2111 and the second protrusion 2121 both cooperate with the groove body 22 to realize the detachable connection between the support member 21 and the groove body 22. The detachable connection method enables the support member 21 to be easily disassembled and installed when maintenance or replacement is required. After being scrapped, it can be 100% disassembled and recycled, reducing waste, complying with the concept of sustainable development, easy to operate, and saving materials and costs.

[0078] Among them, the trough body 22 is provided with a matching groove 221 that matches the first protrusion 2111 and the second protrusion 2121. The size of the matching groove 221 is adapted to the size of the first protrusion 2111 and the second protrusion 2121, and the matching groove 221 is arranged corresponding to the first protrusion 2111 and the second protrusion 2121. A plurality of connecting ribs are provided on the trough body 22, and the connecting ribs extend in a direction away from the trough body 22, and extend into the side pier 4 and are fixedly connected to the side pier 4. The connecting ribs are arranged on the side of the trough body 22 away from the support member 21, and the connecting ribs are arranged corresponding to the matching groove 221. Each matching groove 221 corresponds to a single connecting rib, thereby enhancing the connection strength between the trough body 22 and the side pier 4. The outer layer of the trough body 22 is made of high-strength stainless steel, which can protect the trough body 22 from damage and withstand the impact and pressure of the gate. The middle layer of the trough body 22 is made of basalt fiber reinforced material. When the side pier gate slot 2 is impacted or vibrated, the basalt fiber reinforced material can absorb and disperse energy, reduce damage to the side pier gate slot 2, and improve the overall impact resistance of the side pier gate slot 2. The inner layer of the trough body 22 adopts a self-repairing coating, which can automatically repair tiny cracks or damage on the coating surface to prevent crack expansion, thereby improving the durability of the trough body 22 and extending the service life of the side pier gate slot 2.

[0079] This embodiment also provides a construction method for a door groove structure, comprising the following steps:

[0080] Step S1: During the construction preparation phase, connection bars are reserved in the connection assembly 11;

[0081] Step S2: Building a template according to the design drawings;

[0082] Step S3: Prepare concrete according to design requirements and check the concrete mix ratio and quality standards;

[0083] Step S4: pouring concrete into the formwork to ensure that the middle pier 3 and the middle pier gate slot 1 are completely filled;

[0084] Step S5: Controlling the installation and positioning accuracy of the middle pier gate slot 1;

[0085] Step S6: After the construction is completed, the concrete is cured. After the curing is completed, it is inspected and accepted.

[0086] In this embodiment, first, during the construction preparation stage, the construction workers prepare all the required materials and reserve connecting ribs in the connecting assembly 11, which are used to anchor the middle pier gate slot 1 to the middle pier 3; secondly, the formwork is built according to the design drawings; thirdly, the concrete is prepared according to the design requirements, and the concrete mix ratio and quality standards are checked to ensure that the concrete meets the standards; then, the concrete is poured into the formwork to ensure that the middle pier 3 and the middle pier gate slot 1 are completely filled to ensure that the connection between the middle pier 3 and the middle pier gate slot 1 is firm and can support the opening or closing of the gate; next, the installation and positioning of the middle pier gate slot 1 are precisely controlled to avoid errors caused by position offset and to avoid re-chiseling and reinstallation; finally, after all construction is completed, the concrete is cured, and a protective layer is applied to the surface of the middle pier gate slot 1 for curing, thereby enhancing the service life of the middle pier gate slot 1. After the curing is completed, inspection and acceptance are carried out.

[0087] In step S4, the following steps are specifically included:

[0088] Step S41: During the first phase of concrete pouring, the middle pier 3 and the guide groove 31 reserved for installing the middle pier gate groove 1 are constructed simultaneously;

[0089] Step S42: After the first phase of concrete pouring is completed, the second phase of concrete pouring is performed to fix the middle pier gate slot 1 and the middle pier 3, and a plurality of anti-seepage holes 33 are reserved.

[0090] In step S42, after the first phase concrete pouring is completed and before the second phase concrete is poured to fix the middle pier gate slot 1 and the middle pier 3, the surface of the first phase concrete is roughened, and the interface dust of the joint surface between the first phase concrete and the second phase concrete is blown clean with compressed air, and kept moist so that the interface is in a water-free state.

[0091] In this embodiment, first, when the first phase concrete is poured, the middle pier 3 and the guide groove 31 reserved for installing the middle pier gate slot 1 are constructed simultaneously to provide adjustment space for the positioning of the embedded parts (such as water stop, rail, etc.) of the middle pier gate slot 1; secondly, after the first phase concrete is poured, after the concrete reaches a certain strength, the surface of the first phase concrete is roughened, and the interface dust of the joint surface between the first phase concrete and the second phase concrete is blown clean with compressed air, and kept moist, so that the interface is in a water-free state, which can avoid leakage of the middle pier gate slot 1. After the embedded parts of the middle pier gate slot 1 are accurately positioned, the second phase concrete is poured to fix the middle pier gate slot 1 and the middle pier 3, and a plurality of anti-seepage holes 33 are reserved to accurately fix the position of the embedded parts, avoid the influence of the first phase concrete construction error on the gate installation, ensure the gate opening and closing flexibility, reliable sealing, and reduce construction interference. The second phase concrete is constructed separately after the first phase concrete is poured, which can avoid conflicts with the formwork, support and other processes and reduce the risk of cross-operation.

[0092] In order to enhance the bonding strength between new and old concrete, the joint surface is treated with interface agent or cement slurry, and epoxy interface agent or pure cement slurry is applied. The water-cement ratio of the two is 0.4 to 0.5 to enhance the bonding strength between new and old concrete. The interface agent can fill the tiny pores and unevenness on the concrete surface, provide a larger contact area, and thus improve the bonding strength.

[0093] In order to enhance the connectivity and pull-out resistance of the first-phase concrete, Φ16~25mm anchor bars are pre-embedded in the first-phase concrete. The spacing between two adjacent anchor bars is ≤30cm, and the exposed length of the anchor bars is ≥20d, where d is the diameter of the steel bar, which helps to form mechanical bite.

[0094] In addition, in order to simplify the construction requirements, during the pouring of the first phase concrete, only the foundation strength and the size of the reserved guide groove 31 need to be ensured, simplifying the construction requirements. The second phase concrete uses high-strength or fine stone concrete, and the second phase concrete is mixed with 12% to 15% MgO expansion agent to achieve delayed micro-expansion, with a 14-day expansion rate of ≥0.015%. Alternatively, steel fiber concrete is used, with the mixing amount being 30 to 50 kg / m 3 , thereby improving the crack resistance of the second-phase concrete. Ensure the density around the embedded parts through fine vibration to avoid defects such as voids and honeycombs. Flexible adjustment and maintenance, if there is a deviation in the installation of embedded parts, it can be corrected before the second-phase concrete pouring to reduce rework costs. When the middle pier gate slot 1 is repaired or replaced in the later stage, the second-phase concrete can be partially chiseled out to avoid damaging the main structure of the first-phase concrete. In order to adapt to the needs of complex structures, for the middle pier gate slot 1 that requires embedded bolts, rails or water stop plates, construction in two phases can better control the verticality, flatness and spacing of the embedded parts to meet high-precision requirements. At the same time, pouring in stages can reduce the shrinkage stress concentration of large-volume concrete, reduce the risk of cracking, and facilitate quality control of the entire project.

[0095] Example 2

[0096] The difference between this embodiment and the first embodiment is that, in this embodiment, Figures 7 and 8 As shown, the connecting assembly 11 and the supporting assembly 12 are detachably connected. The detachable connection provides flexibility to the middle pier gate slot 1, which is convenient for adjustment or replacement during construction and maintenance. When the supporting assembly 12 is damaged due to long-term use, it can be easily disassembled and replaced, reducing the disassembly of the overall structure. After scrapping, it can be 100% disassembled, reducing waste, complying with the concept of sustainable development, easy to operate, and saving materials and costs.

[0097] like Figures 7 and 8 As shown, the connecting assembly 11 is provided with a mating portion 111, and the supporting assembly 12 is provided with a connecting portion 121. The mating portion 111 cooperates with the connecting portion 121 to achieve a detachable connection between the connecting assembly 11 and the supporting assembly 12. This allows the middle pier gate slot 1 to be easily disassembled and installed when maintenance or component replacement is required. After being scrapped, it can be 100% disassembled, reducing waste, conforming to the concept of sustainable development, and is easy to operate, saving construction materials and costs. The corresponding arrangement of the mating portion 111 and the connecting portion 121 can improve the accuracy of the connection between the two and avoid damage caused by dimensional deviation. The outer layer of the connecting component 11 is made of high-strength stainless steel, which can protect the connecting component 11 from damage and withstand the impact and pressure of the gate. The middle layer of the connecting component 11 is made of basalt fiber reinforced material. When the middle pier gate slot 1 is impacted or vibrated, the basalt fiber reinforced material can absorb and disperse energy, reduce damage to the middle pier gate slot 1, and improve the overall impact resistance of the middle pier gate slot 1. The inner layer of the connecting component 11 adopts a self-repairing coating, which can automatically repair tiny cracks or damage on the coating surface to prevent crack expansion, thereby improving the durability of the connecting component 11 and extending the service life of the middle pier gate slot 1.

[0098] Specifically, the connection portion 121 is configured as a protrusion, which is a dovetail tenon-type structure, and the mating portion 111 is configured as a mounting groove. There are multiple connection portions 121 and multiple mating portions 111, with each connection portion 121 corresponding to a single mating portion 111. The size of the connection portion 121 matches the size of the mating portion 111, and the protrusion 32 of the connection portion 121 can effectively combine with the mounting groove of the mating portion 111 to form a secure connection, thereby enhancing the stability between the connection assembly 11 and the support assembly 12. The size of the connection portion 121 matches the size of the mating portion 111, ensuring precise docking during connection and reducing operational difficulty. The diameter of the connection portion 121 gradually increases from the bottom toward the mating portion 111, and the two sides of the connection portion 121 are inclined away from the center of the middle pier gate slot 1, which can increase the contact area of the connection and further enhance the firmness of the connection. It also helps to disperse stress when subjected to force and reduce local stress concentration. The dovetail tenon structure has good pull-out resistance and can strengthen the connection strength between the connecting component 11 and the supporting component 12, so that the connecting component 11 and the supporting component 12 can withstand greater tension and shear force. At the same time, the dovetail tenon structure can also make the connecting part 121 and the mating part 111 easy to disassemble and install, and the processing is relatively simple.

[0099] It should be noted that the connecting portion 121 may also be configured as a mounting groove, and the matching portion 111 may be configured as a protrusion.

[0100] Further, such as Figure 8 As shown, the connecting portion 121 is provided with a first groove 1211, and the matching portion 111 is provided with a second groove 1111. The second groove 1111 is convex in a direction away from the connecting portion 121, and the convex surface is a curved surface structure. The first groove 1211 is concave in a direction away from the center pier 3, and the concave surface is a curved surface structure. The diameter of the second groove 1111 is the same as the diameter of the first groove 1211. After the matching portion 111 and the connecting portion 121 are connected, the second groove 1111 and the first groove 1211 form an emergency anti-seepage hole, indicating that the emergency anti-seepage hole is naturally formed after the matching portion 111 and the connecting portion 121 are combined. It is an emergency anti-seepage hole. The emergency anti-seepage hole serves as a secondary water-stopping guarantee, which means that it may not be needed under normal circumstances, but it can play a role when problems arise. The existence of the emergency anti-seepage hole is to provide additional water sealing protection.

[0101] Further, such as Figure 8As shown, the connection component 11 also includes a guide member 114, and the end of the guide member 114 away from the support component 12 is connected to the connecting rib. A filling interval 1141 is provided in the guide member 114, and the filling interval 1141 is located between two adjacent matching parts 111. The bottom of the filling interval 1141 is in the same straight line as the bottom of the matching part 111, and the top of the filling interval 1141 is in the same straight line as the top of the matching part 111, which can evenly transfer the load borne by the matching part 111 to the filling interval 1141. The filling interval 1141 is filled with empty boxes, which can reduce the amount of concrete used without affecting the strength of the connection component 11, reduce the overall dead weight of the middle pier 3, and save construction costs.

[0102] It should be noted that the filling interval 1141 can also be filled with other materials.

[0103] Furthermore, a spacing is provided between the fitting portion 111 and the connecting portion 121, and the spacing ranges from 3 to 5 mm. The spacing is filled with a high-elasticity silicone material. The spacing is an expansion joint, and its width ranges from 3 to 5 mm. The spacing is set to allow the material to expand or contract freely when the temperature changes. By reserving a width of 3 to 5 mm, the changes in the high-elasticity silicone material caused by thermal expansion and contraction can be effectively coped with. 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 the high-elasticity silicone material from being damaged or deformed due to excessive force, improving the stability of the overall structure, and extending the service life.

[0104] Example 3

[0105] This embodiment is different from the first embodiment in that, in this embodiment, step S4 specifically further includes: step S41 : the connecting assembly 11 and the supporting assembly 12 are installed together and the concrete is poured synchronously with the middle pier 3 .

[0106] In this embodiment, first, the connection component 11 and the support component 12 are installed together and the concrete is poured synchronously with the middle pier 3. Pouring together can avoid water seepage or weak strength areas caused by improper treatment of construction joints, improve the anti-seepage strength of the middle pier gate slot 1, and at the same time reduce the repeated scheduling of lifting equipment and the waiting time of manual intervals; secondly, the connection component 11 and the support component 12 need to be fixed during construction to prevent the two from changing in coordination, so as to avoid difficulty in installing the support component 12 into the connection part 121 during the later construction process.

[0107] In order to control the positioning accuracy, an adjustable steel bracket and positioning bolts are used to fix the middle pier gate slot 1. The support system and the template are designed as an integrated whole to ensure that the verticality and horizontality error range of the middle pier gate slot 1 is ≤2mm. When pre-embedded anchor bolts of the middle pier gate slot 1, a total station is used in conjunction with a laser positioning instrument for real-time calibration, and the position is remeasured and locked before pouring. Protective plates 124 are welded on both sides of the connecting component 11. The thickness range of the protective plates 124 is ≥10mm. The protective plates 124 can prevent the deformation of the connecting component 11 caused by the side pressure of the concrete. The filling interval 1141 is filled with foam or empty boxes, which can effectively offset the influence of the buoyancy of the concrete.

[0108] To ensure the quality of the concrete pour, a layered and segmented pouring process was employed, with connection assembly 11 being prioritized. Self-compacting concrete was first poured within a 50cm radius around the middle pier gate slot 1. Vibrators were inserted through pre-placed holes spaced 1m apart to ensure the absence of voids. The main structure of middle pier 3 was then poured. Low-heat, slightly expansive concrete was used in the middle pier gate slot 1 area. MgO expansion agent was incorporated into the concrete to effectively reduce shrinkage stress within the middle pier gate slot 1. A 20mm-wide polyethylene foam strip was reserved at the joint between the middle pier gate slot 1 and the concrete. Circulating cooling water pipes, spaced 0.8m apart, were embedded to control the temperature differential to ≤20°C.

[0109] For construction coordination and progress control, the pouring sequence was simulated through the BIM model, and the steel frame of the middle pier gate slot 1 and the middle pier 3 were prefabricated into integral modules, which helped to reduce on-site assembly time.

[0110] In order to prevent and control economic risks, and to establish a deviation pre-control and insurance mechanism, a third-party monitoring agency was introduced into the installation and acceptance of Zhongdun Gate Slot 1. If the deviation exceeded the standard, work would be stopped and adjusted immediately to avoid rework.

[0111] The present application has been described in detail above. Specific examples have been used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is intended only to facilitate understanding of the present application and its core concepts. It should be noted that, without departing from the principles of the present application, a number of improvements and modifications may be made to the present application by a person skilled in the art, and such improvements and modifications shall fall within the scope of protection of the claims of the present application.
