[0028] To make the objectives, technical solutions, and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other implementations obtained by those of ordinary skill in the art without inventive effort are within the scope of protection of the present invention.

They do not indicate or imply that the devices or components referred to must have a specific direction, be constructed, or operate in a specific direction, and therefore should not be construed as limiting the present 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.

[0030] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms in the present invention depending on the specific circumstances.

[0031] In an embodiment of the present invention, Figures 1 to 9 As shown, the one-step casting system includes a gate groove climbing and turning mold assembly 1, a shaft sliding mold assembly 2 and a feeding assembly 3; wherein, The door slot climbing and turning mold assembly 1 includes a door slot template 12 and a lifting device 11; The outer side wall of the shaft slipform assembly 2 is slidably attached to the outer side wall of the gate groove template 1, and the non-attached outer side wall of the shaft slipform assembly 2 and the non-attached outer side wall of the gate groove template 12 together form a casting circle. The casting space 4 is between the casting circle and the wall of the gate shaft. Figure 1 and Figure 2 The shaft slipform assembly 2 is provided with a lifting device 214 for lifting the shaft slipform assembly 2. The lifting direction of the lifting device 214 is parallel to the depth direction of the gate well. The support end of the lifting device 214 extends into the casting space 4. The feed assembly 3 is arranged on the shaft slipform assembly 2 , the feed end of the feed assembly 3 extends to the wellhead of the gate shaft, and the discharge end of the feed assembly 3 extends to the casting space 4 .

[0032] When pouring the hydraulic concrete structure in the gate well, the worker can feed the mixed concrete into the pouring space 4 through the feeding assembly 3, and pour the concrete from the bottom of the pouring space 4 to the top of the pouring space 4, so that the concrete forms the hydraulic concrete structure in the pouring space 4; Since the concrete is poured gradually from the bottom of the pouring space 4 to the top of the pouring space 4, the solidification speed of the concrete at the bottom of the pouring space 4 is greater than the solidification speed of the concrete at the top of the pouring space 4; When the strength of the hydraulic concrete structure in the corresponding pouring space of the shaft slipform assembly 2 and the gate slot template 12 reaches the demoulding strength, the staff can respectively hoist the shaft slipform assembly 2 and the gate slot template 12 through the lifting device 214 and the lifting device 11 to adjust the positions of the 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, thereby meeting the continuous pouring of the hydraulic concrete structure until the pouring of the hydraulic concrete structure in the gate shaft is completed; In this embodiment, the number of the above-mentioned gate slot templates 12 is multiple, and the multiple gate slot templates 12 are stacked in sequence along the depth direction of the gate well and connected to each other; When the strength of the hydraulic concrete structure in the pouring space corresponding to the lowest gate groove template 12 reaches the demoulding strength, the lowest gate groove template 12 is removed, and the lifting device 11 is used to lift the removed lowest gate groove template 12 above the highest gate groove template 12, and stack it on the highest gate groove template 12, and connect and fix it with the highest gate groove template 12 to become the new highest gate groove template 12. In this operation mode, the lifting device 11 only needs to lift one of the gate groove templates 12, which reduces the burden of the lifting device 11 and can ensure that the positions of the other gate groove templates 12 do not move, so as to reduce the impact on the hydraulic concrete structure. While the lowermost gate groove template 12 is being hoisted upward, the lifting device 214 is controlled to lift the shaft slipform assembly 2, so that the shaft slipform assembly 2 is lifted upward in the depth direction of the gate shaft. The shaft slipform assembly 2 and the new uppermost gate groove template 12 together enclose a new pouring space 4, that is, the pouring space 4 is raised in the depth direction of the gate shaft, meeting the continuous pouring of the hydraulic concrete structure; Repeat the above operations until the hydraulic concrete structure in the gate well is poured.

[0033] When casting the hydraulic concrete structure with this one-time forming casting system, there is no need to proceed in steps, which avoids the formation of joints in the hydraulic concrete structure, 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 of the gate well.

[0034] It should be noted that the above-mentioned fitting outer wall of the shaft slipform assembly 2 refers to the portion of the outer wall of the shaft slipform assembly 2 that fits with the door groove template 12, and the portion of the outer wall of the shaft slipform assembly 2 that does not fit with the door groove template 12 is the non-fitting outer wall; The fitting outer wall of the door groove template 12 refers to the part of the outer wall of the door groove template 12 that fits with the shaft slipform assembly 2, and the part of the outer wall of the door groove template 12 that does not fit with the shaft slipform assembly 2 is the non-fitting outer wall; in this embodiment, the shape enclosed by the shaft slipform assembly 2 and the door groove template 12 is a rectangle, the size of the shaft slipform assembly 2 is larger than the size of the door groove template 12, a part of one side of the well slipform assembly 2 (fitting outer wall) fits with one side of the door groove template 12 (fitting outer wall), the remaining part of one side of the well slipform assembly 2 and the other three sides are the non-fitting outer walls of the shaft slipform assembly 2, and the other three sides of the door groove template 12 are the non-fitting outer walls of the door groove template 12.

[0035] Preferably, among the plurality of door slot templates 12 stacked in sequence, two adjacent door slot templates 12 are fixed by bolts, so that the installation and removal of the door slot templates 12 are more convenient; The above-mentioned hoisting device 11 is a gantry, which is arranged at the wellhead of the gate shaft, and the hoisting end of the gantry can extend into the gate shaft; when the strength of the hydraulic concrete structure corresponding to the lowermost gate slot formwork 12 reaches the demoulding strength, the staff can remove the lowermost gate slot formwork 12, then connect the hoisting end of the gantry to the removed lowermost gate slot formwork 12, and hoist the lowermost gate slot formwork 12 above the uppermost gate slot formwork 12 to complete the installation again.

[0036] In some embodiments, the above-mentioned gate slot formwork 12 includes an intermediate formwork 121 and two side formworks 122, see Figure 4 ; where The two side formworks 122 are oppositely arranged on both sides of the intermediate formwork 121 to form a formwork with a "U" - shaped cross - section, and the shaft slip formwork assembly 2 is slidably fitted to the side of the side formwork 122 away from the intermediate formwork 121; The two side formworks 122 are connected by a turnbuckle A123 to realize the support and limit of the side formworks 122, and an adjusting strut 125 is arranged between the two side formworks 122. The adjusting strut 125 is parallel to the turnbuckle A123. A turnbuckle B124 is arranged on the side of the adjusting strut 125 facing the intermediate formwork 121. The end of the turnbuckle B124 away from the adjusting strut 125 is connected to the intermediate formwork 121 to realize the support and limit of the intermediate formwork 121, so that the structure of the gate slot formwork 12 is more stable and the ability to bear the lateral force of concrete is improved.

[0037] It should be noted that the above - mentioned turnbuckle A123 and turnbuckle B124 are both composed of adjusting rods with left - hand threads and right - hand threads and nuts. The two adjusting rods are respectively arranged at both ends of the nut, and the ends of the two adjusting rods away from the nut are respectively connected to the two side formworks 122. By rotating the nut, the distance between the ends of the two adjusting rods away from the nut can be adjusted to make the formwork support and demoulding of the side formworks 122 more convenient.

[0038] In some embodiments, an extension formwork 127 is arranged on the side of the side formwork 122 away from the intermediate formwork 121. The free side of the extension formwork 127 extends in the direction away from the center of the intermediate formwork 121, and the plane where the extension formwork 127 is located is parallel to the plane where the intermediate formwork 121 is located; The above - mentioned shaft slip formwork assembly 2 is slidably fitted to the free side of the extension formwork 127; Preferably, a sliding wheel A126 is arranged on the above - mentioned extension formwork 127, see Figure 5 and Figure 8 , the sliding wheel A126 is arranged close to the free side of the extension formwork 127, and the sliding wheel A126 is located on the side of the extension formwork 127 facing away from the intermediate formwork 121; The side of the shaft slipform assembly 2 contacts the wheel surface of the sliding wheel A126; When lifting the shaft slipform assembly 2, the sliding wheel A126 can reduce the friction between the shaft slipform assembly 2 and the side template 122, and prevent the shaft slipform assembly 2 from swinging, so that the lifting of the shaft slipform assembly 2 is smoother.

[0039] In some embodiments, the intermediate template 121 is provided with a sleeve bolt 128, 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 is passed through the side of the intermediate template 121 away from the side template 122. Figure 4 ; When the concrete fills the pouring space 4, one end of the anchor rod 129 passes through the middle formwork 121 and is buried in the concrete, which can effectively increase the strength of the hydraulic concrete structure; When removing the door groove template 12, the staff needs to use tools to cut off the portion of the anchor rod 129 outside the hydraulic concrete structure so that the door groove template 12 can be separated from the hydraulic concrete structure and the demoulding is completed; After demoulding is completed, the holes on the hydraulic concrete structure corresponding to the positions of the sleeve bolts 128 are sealed with glue-adjusted mortar to make the surface of the hydraulic concrete structure smooth; When reinstalling the disassembled door slot template 12, the staff needs to reinstall the anchor rod 129 at the sleeve bolt 128 to facilitate subsequent pouring.

[0040] In some embodiments, the above-mentioned shaft slipform assembly 2 includes a main truss 21 and two shaft templates 22, see Figure 1 、 Figure 6 and Figure 7 ;in, Two shaft templates 22 are respectively arranged on opposite sides of the main truss 21; The door groove template 12 is located at the joint of the two shaft templates 22, and the two sides of the door groove template 12 are respectively connected with the side edges of the two shaft templates 22; in this embodiment, there are two groups of door groove templates 12, and each group of door groove templates 12 has multiple numbers. The two groups of door groove templates 12 are respectively located on the opposite sides of the main truss 21, and the two shaft templates 22 are respectively located on the other two sides of the main truss 21. The two shaft templates 22 and the door groove templates 12 in the two door groove templates 1 together form the above-mentioned casting circle.

[0041] In some embodiments, the main truss 21 includes an upper platform 211, a middle platform 212 and a lower platform 213. Figure 6 ;in, The upper platform 211, the middle platform 212 and the lower platform 213 are connected in sequence from top to bottom, and the space height 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; 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; The feeding assembly 3 is arranged 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 arranged close to the edge of the upper platform 211; The 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 below the upper platform 211. The middle platform 212 is provided with a hydraulic pump station that provides hydraulic power to the hydraulic jack. In this embodiment, there are two groups of hydraulic jacks, each group having multiple hydraulic jacks. The two groups of hydraulic jacks alternately support the main truss 21 in sequence to achieve the lifting of the shaft slipform assembly 2. Specifically, during the process of lifting the main truss 21, the first set of hydraulic jacks can be controlled to support the upper end surface of the hydraulic concrete structure that meets the strength standard. At this time, the continuously poured concrete will cover the telescopic rods of the hydraulic jacks. After the subsequently poured concrete solidifies to form the hydraulic concrete structure and the strength meets the standard, the staff can control the telescopic rods of the second set of hydraulic jacks to extend downward and abut against the upper end surface of the subsequently poured hydraulic concrete structure to achieve support for the main truss 21. Subsequently, the first set of hydraulic jacks is controlled to retract so that the telescopic rods of the first set of hydraulic jacks are released from the hydraulic concrete structure, so that the second set of hydraulic jacks can be replaced to continue supporting the main truss 21. Repeat the above steps until the hydraulic concrete structure in the gate well is poured.

[0042] The above-mentioned shaft template 22 includes an upper template and a lower template; wherein the upper template and the lower template are arranged vertically; the lower edge of the lower template is flush with the lower edge of the lower platform 213, and the upper edge of the lower template extends to the middle of the middle platform 212; 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 butted against the lower edge of the upper template; When the strength of the hydraulic concrete structure corresponding to the lower formwork reaches the demoulding strength, the staff can enter the lower platform 213 and remove the lower formwork; Then, the exposed hydraulic concrete structure in the lower platform 213 can be subjected to surface curing. When the hydraulic concrete structure has been subjected to surface curing and has reached a certain strength, water sprinkling curing can be carried out.

[0043] A water tank is provided on the above-mentioned middle platform 212, and a water outlet pipe is provided on the water tank. The water outlet end of the water outlet pipe is provided with a spray gun for spraying water to the hydraulic concrete structure, so that watering maintenance is more convenient.

[0044] In some embodiments, a sliding wheel B221 is provided on the side where the shaft template 22 and the door slot template 12 are in contact. Figure 8 The shaft template 22 slides with the door groove template 12 through the sliding wheel B221 to make the lifting of the shaft template 22 more stable.

[0045] In some embodiments, the above-mentioned feeding assembly 3 includes a receiving hopper 31, a feeding chute 32, a distributor 33 and a plurality of discharge chutes 34, see Figure 1 and Figure 9 ;in, The distributor 33 is arranged on the shaft slipform assembly 2, and a plurality of discharge chutes 34 are arranged around the circumference of the distributor 33; The receiving hopper 31 is located at the wellhead of the gate shaft. 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 delivered to the distributor 33 through the receiving hopper 31, and the concrete is transported to multiple positions around the distributor 33 through the distributor 33 to achieve uniform pouring of concrete.

[0046] Preferably, the above-mentioned feeding assembly 3 further includes a fixed frame, a chute, a descender, a rotary dustpan and a bracket; wherein, The distributor 33 is fixed to the middle of the upper platform 211 through a bracket; The rotary dustpan is rotated by a rotary motor and is arranged in the distributor 33. The rotation axis of the rotary dustpan is parallel to the depth direction of the gate well, and the bearing surface of the rotary dustpan is arranged at an angle to the rotation axis of the rotary dustpan. The fixing frame is set on the wall of the gate pit, the chute is fixed to the wall of the gate pit through the fixing frame, the receiving hopper 31 is set at the inlet end of the chute, the descender is set at the outlet end of the chute, and the discharge end of the descender is connected to the distributor 33 through the feed chute 32; When pouring hydraulic concrete structures, the concrete pump truck pours the mixed concrete into the receiving hopper 31. After passing through the chute and the descender, the concrete slowly flows into the distributor 33 through the feed chute 32, and then is evenly distributed to multiple discharge chutes 34 through a rotating dustpan, and flows into the circumferential pouring space 4 of the distributor 33, thereby achieving uniform pouring of the hydraulic concrete structure.

[0047] It is worth noting that during the pouring of the hydraulic concrete structure, the rotary dustpan rotates continuously, and the concrete flowing out of the feed chute 32 is evenly distributed to the multiple discharge chutes 34 under the influence of the bearing surface of the rotary dustpan, so as to achieve uniform pouring of the hydraulic concrete structure. The distributor is a cylindrical container with a feed port on the top and multiple discharge ports along the circumference of the bottom. The multiple discharge ports correspond to the multiple discharge chutes 34 one by one to achieve uniform distribution of concrete.

[0049] This method can meet the requirements of continuous pouring of the hydraulic concrete structure until the pouring of the hydraulic concrete structure in the gate well is completed; the entire pouring process does not need to be carried out in steps, which avoids the generation of joints in the hydraulic concrete structure, 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.
