Description

Technical Field

[0001] This invention belongs to the field of gate well construction technology, and specifically relates to a one-time casting system and one-time casting method for constructing hydraulic concrete structures in gate wells. Background Technology

[0002] In recent years, my country's hydropower development has been accelerating its extension into complex geological areas such as high-altitude and deep canyons in the southwest, which has placed stringent requirements on the construction efficiency, safety performance and durability of hydraulic concrete structures.

[0003] As the core structure of the water conveyance system of a hydropower station, the construction quality of the hydraulic concrete structure of the gate well directly affects the operational safety and service life of the hydropower station.

[0004] Currently, the construction of hydraulic concrete structures in gate wells mostly adopts staged casting or on-site masonry techniques; among them...

[0005] Hydraulic concrete structures constructed using the step-by-step casting process have numerous joints and poor integrity, making them prone to leakage or cracks due to uneven settlement, and the support procedures are complex.

[0006] On-site masonry construction uses prefabricated components for assembly. While this method can shorten the construction period, the large size and weight of the prefabricated components make transportation and hoisting difficult, increasing the difficulty of construction. It also has the same problems of many joints and poor overall integrity. Summary of the Invention

[0007] This invention provides a one-time casting system and one-time casting method to solve the technical problems of multiple joints, poor integrity, and increased construction difficulty in hydraulic concrete structures in gate wells constructed by step casting or on-site masonry processes in the prior art.

[0008] This invention is achieved through the following technical solution:

[0009] A one-time casting system includes a door slot template, a shaft slipform assembly, and a material feeding assembly;

[0010] The outer wall of the vertical shaft slipform assembly slides and adheres to the outer wall of the gate slot template. The non-adhering outer wall of the vertical shaft slipform assembly and the non-adhering outer wall of the gate slot template together form a casting ring. A casting space is formed between the casting ring and the well wall of the gate well. The vertical shaft slipform assembly is equipped with a lifting device for raising and lowering the vertical shaft slipform assembly. The lifting direction of the lifting device is parallel to the depth direction of the gate well, and the support end of the lifting device extends into the casting space.

[0011] The feeding assembly is installed on the vertical shaft sliding formwork assembly. The feeding end of the feeding assembly extends to the wellhead of the gate shaft, and the discharging end of the feeding assembly extends to the pouring space.

[0012] When the strength of the hydraulic concrete structure in the corresponding pouring space of the vertical shaft slipform assembly and the gate slot template reaches the demolding strength, the position of the vertical shaft slipform assembly and the gate slot template can be adjusted by the lifting device and the hoisting device respectively, so that the pouring ring rises along the depth direction of the gate shaft and forms a new pouring space with the well wall of the gate shaft, which meets the requirements for continuous pouring of the hydraulic concrete structure until the hydraulic concrete structure in the gate shaft is completed.

[0013] To better realize the present invention, the above structure is further optimized, and the door groove template includes a middle template and two side templates;

[0014] Two side templates are set opposite each other on both sides of the middle template. The vertical shaft sliding formwork assembly slides and fits against the side templates away from the middle template. The two side templates are connected and limited by turnbuckle A. An adjusting support rod is set between the two side templates. The adjusting support rod is parallel to the turnbuckle A. A turnbuckle B is set on the side of the adjusting support rod facing the middle template. The end of the turnbuckle B away from the adjusting support rod is connected to the middle template.

[0015] To better realize the present invention, further optimization is made to the above structure. An extension template is provided on the side of the side template away from the middle template. The free side of the extension template extends away from the center of the middle template, and the plane where the extension template is located is parallel to the plane where the middle template is located.

[0016] The vertical shaft sliding formwork assembly and the extended template slide freely together.

[0017] To better realize the present invention, the above structure is further optimized. A sleeve bolt is provided on the intermediate template. The axis of the sleeve bolt is perpendicular to the plane where the intermediate template is located. An anchor rod is provided in the sleeve bolt. One end of the anchor rod passes through the side of the intermediate template away from the side template.

[0018] To better realize the present invention, further optimizations are made to the above structure, wherein the number of gate slot templates is multiple, and the multiple gate slot templates are stacked sequentially and connected to each other along the depth direction of the gate well.

[0019] To better realize the present invention, further optimizations are made to the above structure, wherein the vertical shaft slipform assembly includes a main truss and two vertical shaft templates;

[0020] The two vertical shaft formworks are respectively set on opposite sides of the main truss;

[0021] The door slot template is located at the joint of the two vertical shaft templates, and the two sides of the door slot template are connected to the sides of the two vertical shaft templates respectively.

[0022] To better realize the present invention, further optimizations are made to the above structure, wherein the main truss includes an upper platform, a middle platform and a lower platform;

[0023] The upper platform, middle platform, and lower platform are connected sequentially from top to bottom, and the height of the space between the upper platform and the middle platform, as well as between the middle platform and the lower platform, is sufficient for people to stand; ladders extending to the middle platform and the upper platform are respectively installed on the lower platform and the middle platform.

[0024] The edge of the upper platform extends above the pouring space, and the lifting device is positioned close to the edge of the upper platform;

[0025] The feeding assembly is located in the middle of the upper platform.

[0026] To better realize the present invention, the above structure is further optimized. A sliding wheel B is provided on the side of the shaft template that is in contact with the door slot template, and the shaft template slides with the door slot template through the sliding wheel B.

[0027] To better realize the present invention, the above structure is further optimized, and the feeding assembly includes a receiving hopper, a feeding chute, a distributor and multiple discharge chutes;

[0028] The material distributor is installed on the vertical shaft sliding formwork assembly, and multiple discharge chutes are arranged around the circumference of the material distributor.

[0029] The receiving hopper is located at the wellhead of the gate well. The outlet end of the receiving hopper is connected to the distributor through the feed chute. The discharge end of the distributor is connected to the casting space through multiple discharge chutes.

[0030] The one-time casting method, implemented using the aforementioned one-time casting system, includes the following steps:

[0031] The gate slot template, vertical shaft slipform assembly, and material feeding assembly of the one-time casting system are hoisted into the gate shaft for installation.

[0032] Concrete is poured into the pouring space via the feeding assembly;

[0033] When the strength of the hydraulic concrete structure corresponding to the vertical shaft slipform assembly and the gate slot template reaches the demolding strength, the vertical shaft slipform assembly and the gate slot template can be hoisted upward along the depth direction of the gate shaft using the lifting device and hoisting device respectively, so that the pouring space rises along the depth direction of the gate shaft until the hydraulic concrete structure in the gate shaft is poured.

[0034] Maintenance of hydraulic concrete structures.

[0035] Compared with the prior art, the present invention has the following advantages:

[0036] In the one-step casting system provided by this invention, both the gate slot template and the vertical shaft slipform assembly can move along the depth direction of the gate well and together form a casting circle. When the strength of the hydraulic concrete structure in the corresponding casting space of the vertical shaft slipform assembly and the gate slot template reaches the demolding strength, the vertical shaft slipform assembly and the gate slot template can be lifted upward along the depth direction of the gate well by lifting and hoisting devices, respectively, so that the casting space rises along the depth direction of the gate well, satisfying the continuous casting of the hydraulic concrete structure until the hydraulic concrete structure in the gate well is completed. This one-step casting system eliminates the need for step-by-step casting of the hydraulic concrete structure, avoids the generation of joints, improves the integrity and shear strength of the hydraulic concrete structure, thereby ensuring the construction quality of the hydraulic concrete structure in the gate well and reducing the construction difficulty.

[0052] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0053] In the description of this invention, it should be noted that, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention 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, and therefore should not be construed as a limitation of the invention. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0054] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0055] In embodiments of the present invention, such as Figures 1 to 9 As shown, the one-time casting system includes a gate slot climbing and flipping formwork assembly 1, a vertical shaft sliding formwork assembly 2, and a material feeding assembly 3; wherein,

[0056] The door slot climbing and flipping formwork assembly 1 includes a door slot template 12 and a lifting device 11;

[0057] The outer wall of the vertical shaft slipform assembly 2 slides and adheres to the outer wall of the gate slot template 1. The non-adhering outer wall of the vertical shaft slipform assembly 2 and the non-adhering outer wall of the gate slot template 12 together form a casting ring. The space between the casting ring and the gate shaft wall is the casting space 4. (See below) Figure 1 and Figure 2 The vertical shaft sliding formwork assembly 2 is provided with a lifting device 214 for raising and lowering the vertical shaft sliding formwork assembly 2. The lifting direction of the lifting device 214 is parallel to the depth direction of the gate shaft, and the support end of the lifting device 214 extends into the pouring space 4.

[0058] The feeding component 3 is installed on the vertical shaft sliding formwork component 2. The feeding end of the feeding component 3 extends to the wellhead of the gate well, and the discharging end of the feeding component 3 extends to the casting space 4.

[0059] When pouring the hydraulic concrete structure in the gate well, the workers can send the mixed concrete into the pouring space 4 through the feeding component 3, and pour it from the bottom to the top of the pouring space 4, so that the concrete forms a hydraulic concrete structure in the pouring space 4.

[0060] Since the concrete is poured gradually from the bottom to the top of the pouring space 4, the concrete at the bottom of the pouring space 4 sets faster than the concrete at the top of the pouring space 4.

[0061] When the strength of the hydraulic concrete structure in the corresponding pouring space of the vertical shaft slipform assembly 2 and the gate slot template 12 reaches the demolding strength, the workers can lift the vertical shaft slipform assembly 2 and the gate slot template 12 respectively through the lifting device 214 and the hoisting device 11 to adjust the position of the vertical shaft slipform assembly 2 and the gate slot template 12, so that the pouring ring rises along the depth direction of the gate shaft and forms a new pouring space 4 with the well wall of the gate shaft, which meets the continuous pouring of the hydraulic concrete structure until the hydraulic concrete structure in the gate shaft is poured.

[0062] In this embodiment, there are multiple gate slot templates 12, and the multiple gate slot templates 12 are stacked sequentially and connected to each other along the depth direction of the gate well.

[0063] When the strength of the hydraulic concrete structure in the pouring space corresponding to the bottommost door slot template 12 reaches the demolding strength, the bottommost door slot template 12 is removed, and the removed bottommost door slot template 12 is hoisted above the topmost door slot template 12 using the lifting device 11, and stacked on the topmost door slot template 12, and connected and fixed with the topmost door slot template 12 to become the new topmost door slot template 12. In this operation, the lifting device 11 only needs to hoist one door slot template 12, reducing the burden on the lifting device 11, and can ensure that the positions of the other door slot templates 12 do not move, so as to reduce the impact on the hydraulic concrete structure.

[0064] While hoisting the bottom gate slot template 12 upward, control the lifting device 214 to lift the vertical shaft sliding formwork assembly 2, so that the vertical shaft sliding formwork assembly 2 is lifted upward along the depth direction of the gate shaft. The vertical shaft sliding formwork assembly 2 and the new top gate slot template 12 together form a new pouring space 4, that is, the pouring space 4 is raised along the depth direction of the gate shaft to meet the continuous pouring of the hydraulic concrete structure.

[0065] Repeat the above steps until the hydraulic concrete structure in the gate well is poured.

[0066] This one-time casting system eliminates the need for step-by-step casting of hydraulic concrete structures, avoiding the formation of joints and improving the overall integrity and shear strength of the hydraulic concrete structure. This ensures the construction quality of the hydraulic concrete structure in the gate well and reduces the construction difficulty of the gate well.

[0067] It should be noted that the outer side wall of the vertical shaft sliding formwork assembly 2 mentioned above refers to the part of the outer side wall of the vertical shaft sliding formwork assembly 2 that is in contact with the door groove template 12, while the part of the outer side wall of the vertical shaft sliding formwork assembly 2 that is not in contact with the door groove template 12 is the non-in contact outer side wall.

[0068] The outer wall of the door slot template 12 that is in contact with the vertical shaft sliding formwork assembly 2 refers to the part of the outer wall of the door slot template 12 that is in contact with the vertical shaft sliding formwork assembly 2. The part of the outer wall of the door slot template 12 that is not in contact with the vertical shaft sliding formwork assembly 2 is the non-in contact outer wall. In this embodiment, the shape formed by the vertical shaft sliding formwork assembly 2 and the door slot template 12 is rectangular. The size of the vertical shaft sliding formwork assembly 2 is larger than the size of the door slot template 12. A part of one side of the vertical shaft sliding formwork assembly 2 (the outer wall that is in contact with the door slot template 12) is in contact with one side of the door slot template 12 (the outer wall that is in contact with the door slot template 12). The remaining part of one side of the vertical shaft sliding formwork assembly 2 and the other three sides are the non-in contact outer walls of the vertical shaft sliding formwork assembly 2. The other three sides of the door slot template 12 are the non-in contact outer walls of the door slot template 12.

[0069] Preferably, in the above-mentioned plurality of door slot templates 12 stacked sequentially, two adjacent door slot templates 12 are fixed by bolts to make the installation and disassembly of the door slot templates 12 more convenient.

[0070] The aforementioned lifting device 11 is a gantry frame, which is installed at the wellhead of the gate well. The lifting end of the gantry frame can extend into the gate well. When the strength of the hydraulic concrete structure corresponding to the bottom gate slot template 12 reaches the demolding strength, the workers can remove the bottom gate slot template 12. Then, the lifting end of the gantry frame is used to connect the removed bottom gate slot template 12, and the bottom gate slot template 12 is hoisted above the top gate slot template 12 to complete the reinstallation.

[0071] In some embodiments, the door groove template 12 described above includes a middle template 121 and two side templates 122, see [link / reference] Figure 4 ;in,

[0072] Two side templates 122 are arranged opposite to each other on both sides of the middle template 121 to form a template with a cross-sectional shape of "U". The vertical shaft sliding formwork assembly 2 slides and fits against the side template 122 away from the middle template 121.

[0073] Two side templates 122 are connected by turnbuckles A123 to support and limit the side templates 122. An adjusting strut 125 is provided between the two side templates 122. The adjusting strut 125 is parallel to the turnbuckles A123. A turnbuckle B124 is provided on the side of the adjusting strut 125 facing the middle template 121. The end of the turnbuckle B124 away from the adjusting strut 125 is connected to the middle template 121 to support and limit the middle template 121. This makes the structure of the door slot template 12 more stable and improves its ability to withstand the lateral force of concrete.

[0074] It should be noted that the turnbuckles A123 and B124 mentioned above are both composed of adjusting rods with left-hand and right-hand threads and nuts. The two adjusting rods are respectively set at both ends of the nut. The ends of the two adjusting rods away from the nut are respectively connected to the two side templates 122. By rotating the nut, the distance between the ends of the two adjusting rods away from the nut can be adjusted, so as to make the formwork support and demolding of the side templates 122 more convenient.

[0075] In some embodiments, an extension template 127 is provided on the side of the side template 122 away from the middle template 121. The free side of the extension template 127 extends away from the center of the middle template 121, and the plane of the extension template 127 is parallel to the plane of the middle template 121.

[0076] The aforementioned vertical shaft sliding formwork assembly 2 and the extended template 127 slide and fit together on their free sides;

[0077] Preferably, the aforementioned extension template 127 is provided with a sliding wheel A126, see [reference]. Figure 5 and Figure 8 The sliding wheel A126 is arranged close to the free side of the extension template 127, and the sliding wheel A126 is located on the side of the extension template 127 that is away from the middle template 121.

[0078] The side of the vertical shaft sliding formwork assembly 2 is in contact with the wheel surface of the sliding wheel A126;

[0079] When lifting the vertical shaft sliding formwork assembly 2, the sliding wheel A126 can reduce the friction between the vertical shaft sliding formwork assembly 2 and the side template 122, and prevent the vertical shaft sliding formwork assembly 2 from swaying, so that the lifting of the vertical shaft sliding formwork assembly 2 is smoother.

[0080] In some embodiments, a sleeve bolt 128 is provided on the intermediate template 121, the axis of the sleeve bolt 128 is perpendicular to the plane where the intermediate template 121 is located, and an anchor rod 129 is provided in the sleeve bolt 128. One end of the anchor rod 129 protrudes from the side of the intermediate template 121 away from the side template 122. See [reference needed] Figure 4 ;

[0081] When the concrete fills the pouring space 4, the end of the anchor rod 129 that protrudes from the intermediate formwork 121 is embedded in the concrete, which can effectively increase the strength of the hydraulic concrete structure.

[0082] When dismantling the door slot formwork 12, workers need to use tools to cut off the part of the anchor rod 129 located outside the hydraulic concrete structure so that the door slot formwork 12 can be separated from the hydraulic concrete structure and demolding can be completed.

[0083] After demolding, the holes corresponding to the sleeve bolts 128 on the hydraulic concrete structure are sealed with adhesive-modified mortar to make the surface of the hydraulic concrete structure smooth.

[0084] When reinstalling the disassembled door slot template 12, workers need to reinstall the anchor rod 129 at the sleeve bolt 128 to facilitate subsequent pouring.

[0085] In some embodiments, the aforementioned vertical shaft slipform assembly 2 includes a main truss 21 and two vertical shaft templates 22, see [link / reference]. Figure 1 , Figure 6 and Figure 7 ;in,

[0086] Two vertical shaft formwork panels 22 are respectively set on opposite sides of the main truss 21;

[0087] The door slot template 12 is located at the joint of the two vertical shaft templates 22, and the two sides of the door slot template 12 are respectively connected to the sides of the two vertical shaft templates 22. In this embodiment, there are two sets of door slot templates 12, and each set contains multiple door slot templates 12. The two sets of door slot templates 12 are located on opposite sides of the main truss 21, and the two vertical shaft templates 22 are located on the other two sides of the main truss 21. The two vertical shaft templates 22 and the door slot templates 12 in the two door slot templates 1 together form the above-mentioned casting ring.

[0088] In some embodiments, the main truss 21 described above includes an upper platform 211, a middle platform 212, and a lower platform 213, see [reference needed]. Figure 6 ;in,

[0089] The upper platform 211, the middle platform 212 and the lower platform 213 are connected from top to bottom, and the height of the space between the upper platform 211 and the middle platform 212 and between the middle platform 212 and the lower platform 213 is sufficient for people to stand.

[0090] Ladders extending to the middle platform 212 and the upper platform 211 are respectively provided on the lower platform 213 and the middle platform 212;

[0091] The feeding assembly 3 is located in the middle of the upper platform 211; the edge of the upper platform 211 extends to the top of the pouring space 4, and the lifting device 214 is located close to the edge of the upper platform 211.

[0092] The aforementioned lifting device 214 is a hydraulic jack. The base of the hydraulic jack is fixedly mounted on the upper platform 211. The telescopic rod of the hydraulic jack can extend downwards from the upper platform 211. A hydraulic pump station that provides hydraulic power to the hydraulic jack is installed on the middle platform 212. In this embodiment, there are two sets of hydraulic jacks, and each set contains multiple hydraulic jacks. The two sets of hydraulic jacks alternately support the main truss 21 to realize the lifting of the vertical shaft sliding formwork assembly 2.

[0093] Specifically, during the process of lifting the main truss 21, the first set of hydraulic jacks can be controlled to support the upper surface of the hydraulic concrete structure that meets the strength requirements. At this time, the concrete that continues to be poured will cover the extension rod of the hydraulic jacks. After the concrete poured later solidifies to form the hydraulic concrete structure and meets the strength requirements, the workers can control the extension rod of the second set of hydraulic jacks to extend downward and abut against the upper surface of the hydraulic concrete structure poured later, thereby supporting the main truss 21.

[0094] Subsequently, the first set of hydraulic jacks is controlled to retract so that the telescopic rod of the first set of hydraulic jacks is released from the hydraulic concrete structure, so that the second set of hydraulic jacks can be replaced to continue supporting the main truss 21.

[0095] Repeat the above steps until the hydraulic concrete structure in the gate well is poured.

[0096] The aforementioned vertical shaft formwork 22 includes an upper formwork and a lower formwork; wherein, the upper formwork and the lower formwork are arranged vertically; the lower edge of the lower formwork is flush with the lower edge of the lower platform 213, and the upper edge of the lower formwork extends to the middle of the middle platform 212;

[0097] The upper edge of the upper template is flush with the upper edge of the upper platform 211, the lower edge of the upper template extends to the middle of the middle platform 212, and the upper edge of the lower template is connected to the lower edge of the upper template.

[0098] When the strength of the hydraulic concrete structure corresponding to the current formwork reaches the demolding strength, workers can enter the lower platform 213 and remove the lower formwork;

[0099] Then, the exposed hydraulic concrete structure can be plastered and cured in the lower platform 213. After the hydraulic concrete structure has been plastered and cured and has reached a certain strength, water curing can be carried out.

[0100] The aforementioned central platform 212 is equipped with a water storage tank, and the water storage tank is equipped with a water outlet pipe. The water outlet end of the water outlet pipe is equipped with a spray gun for easy spraying of water onto the hydraulic concrete structure, so as to make watering and maintenance more convenient.

[0101] In some embodiments, a sliding wheel B221 is provided on the side of the shaft template 22 that is in contact with the door slot template 12, see [reference]. Figure 8 The vertical shaft template 22 slides with the door slot template 12 via the sliding wheel B221, so that the lifting of the vertical shaft template 22 is more stable.

[0102] In some embodiments, the feeding assembly 3 described above includes a receiving hopper 31, a feeding chute 32, a distributor 33, and a plurality of discharge chutes 34. See also Figure 1 and Figure 9 ;in,

[0103] The material distributor 33 is installed on the vertical shaft sliding mold assembly 2, and multiple discharge chutes 34 are arranged around the circumference of the material distributor 33.

[0104] The receiving hopper 31 is located at the wellhead of the gate well. The outlet end of the receiving hopper 31 is connected to the distributor 33 through the feed chute 32. The discharge end of the distributor 33 is connected to the pouring space 4 through multiple discharge chutes 34. The mixed concrete can be sent to the distributor 33 through the receiving hopper 31. The distributor 33 delivers the concrete to multiple positions around the distributor 33, so as to achieve uniform pouring of concrete.

[0105] Preferably, the above-mentioned feeding assembly 3 further includes a fixed frame, a chute, a decelerator, a rotating hopper, and a support; wherein,

[0106] The feeder 33 is fixed to the middle of the upper platform 211 by a bracket;

[0107] The rotating scoop is mounted in the distributor 33 by a rotating motor. The rotation axis of the rotating scoop is parallel to the depth direction of the gate well, and the bearing surface of the rotating scoop is arranged at an angle to the rotation axis of the rotating scoop.

[0108] The fixing frame is set on the well wall of the gate well, and the chute is fixed on the well wall of the gate well through the fixing frame. The receiving hopper 31 is set at the inlet end of the chute, and the decelerator is set at the outlet end of the chute. The discharge end of the decelerator is connected to the distributor 33 through the feed chute 32.

[0109] When pouring hydraulic concrete structures, the concrete pump truck pours the mixed concrete into the receiving hopper 31. After passing through the chute and decelerator, the concrete slowly flows into the distributor 33 through the feed chute 32. Then, it is evenly distributed to multiple discharge chutes 34 by a rotating scoop and flows into the circumferential pouring space 4 of the distributor 33, so as to achieve uniform pouring of hydraulic concrete structures.

[0110] It is worth noting that during the pouring of the hydraulic concrete structure, the rotating chute continues to rotate, and the concrete flowing out of the feed chute 32 will be evenly distributed to multiple discharge chutes 34 under the influence of the bearing surface of the rotating chute, so as to achieve uniform pouring of the hydraulic concrete structure.

[0111] The material distributor is a cylindrical container with a feed inlet at the top and multiple discharge outlets along the circumference at the bottom. Each discharge outlet corresponds to a discharge chute 34, thus achieving uniform distribution of concrete.

[0112] Based on the aforementioned one-time casting system, this embodiment provides a one-time casting method. This method employs the aforementioned one-time casting system and includes the following steps:

[0113] The gate slot template 12, the vertical shaft sliding formwork assembly 2, and the feeding assembly 3 in the one-time casting system are hoisted into the gate shaft for installation.

[0114] Concrete is poured into the pouring space 4 through the feeding component 3;

[0115] When the strength of the hydraulic concrete structure corresponding to the vertical shaft slipform assembly 2 and the bottom gate slot template 12 reaches the demolding strength, the bottom gate slot template 12 can be removed, and the positions of the vertical shaft slipform assembly 2 and the bottom gate slot template 12 can be adjusted by the lifting device 214 and the hoisting device 11 respectively. The bottom gate slot template is hoisted above the top gate slot template 12 and reinstalled, so that the pouring space 4 rises along the depth direction of the gate shaft, and the hydraulic concrete structure in the gate shaft is poured.

[0116] Maintenance of hydraulic concrete structures.

[0117] This method enables continuous pouring of hydraulic concrete structures until the hydraulic concrete structure in the gate well is completed. The entire pouring process does not require step-by-step pouring, avoiding joints in the hydraulic concrete structure, improving the integrity and shear strength of the hydraulic concrete structure, thereby ensuring the construction quality of the hydraulic concrete structure in the gate well and reducing the construction difficulty.

[0118] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
