Description

Technical Field

[0001] This invention belongs to the field of gate well construction technology, specifically relating to a multi-hole gate well and gate slot synchronous one-time casting and forming equipment. Background Technology

[0002] In recent years, the construction of pumped storage and high dam power stations has increased significantly. Most of these power stations are located in complex geological areas such as high altitudes and deep canyons, which places stringent requirements on the construction quality, safety performance, and construction efficiency of hydraulic concrete structures. Among these, the gate well, as the core structure of the water conveyance system of a hydropower station, directly affects the operational safety and service life of the hydropower station due to the quality of its concrete structure construction.

[0003] Currently, due to their complex structure and limitations imposed by gate embeddings and ventilation ladder embeddings, the traditional construction of multi-hole gate wells often employs a layered and segmented pouring method using scaffolding and small formwork assembly. Gate embeddings are installed first, followed by the pouring of the second phase of concrete. This approach is problematic due to the confined space, varied structures, high scaffolding heights, numerous types of embedded parts, and large amounts of formwork assembly. Material transportation within the well is difficult, leading to significant construction safety risks and low efficiency. Furthermore, the layered and segmented concrete pouring results in numerous joints, poor overall integrity, and susceptibility to leakage or cracking due to uneven settlement. The construction process is also extremely complex and inefficient.

[0004] To address the aforementioned problems, Chinese invention patent application CN120505946A discloses a one-time casting system and method. This system includes a gate slot template, a shaft slipform assembly, and a material feeding assembly. The gate slot template and shaft slipform assembly together form a casting ring, and a lifting and hoisting device is used to achieve continuous sliding of the template system, thereby completing the one-time casting of the hydraulic concrete structure in the gate shaft. However, this solution still has the following shortcomings:

[0005] First, its formwork system is only designed for the construction of a single gate well and cannot simultaneously complete the one-time casting of multiple openings (such as gate wells and ventilation shafts). In actual projects, multi-hole gate wells often need to be equipped with multiple functional chambers such as ventilation shafts and cable shafts. If the above-mentioned scheme is used for construction in stages, it will not only increase the number of times the formwork is installed and dismantled and the construction cycle, but also create cold joints at the connection points between the chambers, affecting the overall structural strength and seepage prevention performance.

[0006] Secondly, the door slot formwork in the above-mentioned scheme needs to be lifted layer by layer using a lifting device. This involves removing the bottom formwork and hoisting it to the top for reinstallation. The operation is cumbersome, and concrete pouring needs to be paused during the formwork lifting process, reducing the continuity of construction. At the same time, this lifting method requires high positioning accuracy of the formwork, and repeated disassembly and assembly can easily lead to formwork deformation or loosening of connections, affecting the forming quality of the door slot.

[0007] Third, in the above scheme, the door slot template and the vertical shaft sliding formwork assembly are only connected and slid together by sliding wheels, lacking reliable lateral support and positioning structure. During the slipforming process, it is easy to deviate or shake, making it difficult to ensure the coordinated control accuracy between the template systems when multiple holes are constructed simultaneously.

[0008] Fourth, the material feeding system in the above scheme uses chutes and distributors for material distribution, but no effective buffer and anti-segregation devices are set up. When the material is fed from a high drop, the concrete is prone to aggregate separation, which affects the pouring quality. Moreover, the discharge position is relatively fixed, which makes it difficult to adapt to the uniform material distribution requirements of different areas of the multi-hole formwork system.

[0009] Therefore, it is necessary to develop a device that can simultaneously complete the one-time casting and forming of multi-hole gate wells and gate slots to solve the problems in the existing technology, such as the inability to construct multiple well chambers at the same time, the complexity of template lifting operation, the difficulty of coordinated positioning, and uneven material distribution. Summary of the Invention

[0010] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a multi-hole gate well and gate slot synchronous one-time casting equipment that can construct multiple well chambers at the same time, the template can be continuously slid up without flipping the template, and the multi-hole gate well and gate slot can be cast in one time.

[0011] The technical solution adopted to solve the above technical problems is: a multi-hole gate well and gate slot synchronous one-time casting and forming equipment, including a template system, a template support system, a template slip system, an auxiliary operation platform, a control system, a material feeding system, and a gate slot forming system;

[0012] The template system includes a first template system, a second template system, and a third template system. The first template system is used to form a gate well, and the second and third template systems are used to form a ventilation well.

[0013] The template support system is installed inside the first template system, the second template system, and the third template system;

[0014] The template sliding system includes a first sliding device and a second sliding device. The first sliding device is disposed between the first template system and the second template system, and between the first template system and the third template system. The second sliding device is disposed at the other end of the first template system, the second template system, and the third template system.

[0015] The auxiliary operation platform is located below the template system and is used to place operating tools and accommodate operators. The control system is located on the auxiliary operation platform and controls the operation of the template sliding system.

[0016] The material feeding system is located above the formwork system and is used to transport the concrete to the pouring space.

[0017] The gate slot forming system is set on both sides of the first template system and is cast together with the gate well and ventilation well in one go.

[0018] The first slipform device of the present invention is composed of two second slipform devices connected by a connecting plate. The second slipform device includes a pre-embedded climbing rod set in the cast-in-place concrete below the lintel of the multi-hole gate well. A stepping hydraulic climbing device is installed through the pre-embedded climbing rod. The base of the stepping hydraulic climbing device is fixed on a steel plate. A connecting channel steel is vertically installed at the lower end of the steel plate away from the climbing rod. A stiffening plate is installed between the connecting channel steel and the steel plate.

[0019] The stepping hydraulic climbing device of the present invention is a through-hole hydraulic jack, and the through-hole hydraulic jack is controlled by a control system.

[0020] The door slot forming system of the present invention includes several forming units. Each forming unit includes a track panel. A set of reinforcing I-beams is vertically arranged at both ends of one side of the track panel. Reinforcing plates are provided at both the upper and lower ends of the reinforcing I-beams. The reinforcing plates are connected to reinforcing rods pre-embedded in the cast-in-place concrete below the lintel of the multi-hole gate well through at least two sets of connecting rods.

[0021] The connecting rod of the present invention is an adjustable telescopic rod, and its two ends are welded and fixed to the reinforcing plate and the reinforcing rod, respectively.

[0022] The first template system, the second template system, and the third template system of the present invention each include a steel template panel, and a template support system is welded to the back of the template panel. The template support system includes reinforcing ribs distributed in a grid pattern.

[0023] The auxiliary operation platform of the present invention includes a first hanging basket, a second hanging basket, and a third hanging basket. The first hanging basket, the second hanging basket, and the third hanging basket are respectively set to the first template system, the second template system, and the third template system. The control system is set inside the first hanging basket.

[0024] The template sliding system of the present invention also includes a synchronization control module, which is electrically connected to the control system and is used to control the lifting speed of the first sliding device and the second sliding device to be consistent.

[0025] The feeding system of the present invention includes a feeding hopper, and a number of feeding steel pipes connected by connecting flanges are provided at the lower part of the feeding hopper. A buffer pipe with a closed lower part is provided at the end of the feeding steel pipe. The side wall of the buffer pipe is inclined and has a discharge port. The discharge port is connected to a discharge hose by a wire rope clamp.

[0026] The feeding system of the present invention also includes a vibration device, which is disposed on the feeding steel pipe or buffer pipe.

[0027] Compared with the prior art, the present invention has the following advantages:

[0028] 1. This invention, by setting up a first template system (forming the gate well) and second and third template systems (forming the ventilation well), and configuring a template slip-lift system and a gate slot forming system, can simultaneously complete the pouring of the lining concrete for the gate well and the ventilation wells on both sides, as well as the one-time forming of the gate slot track. Compared with traditional layered and segmented pouring or single-well phased construction, it avoids construction cold joints between multiple well chambers, significantly improves the shear strength, impermeability, and durability of the overall structure, and ensures the construction quality of the hydraulic concrete structure.

[0029] 2. The template slipform system of this invention adopts a through-type stepping hydraulic climbing device. The climbing device automatically climbs upward along the pre-embedded climbing rod, driving the template system to rise continuously. Compared with the formwork flipping method described in the prior art patent application CN120505946A, which requires dismantling, hoisting, and reinstalling the door slot template layer by layer, there is no need to stop concrete pouring, the construction continuity is stronger, the operation is simpler, and the deformation and positioning errors caused by multiple dismantling and reassembly of the template are avoided, thus improving the forming accuracy of the door slot.

[0030] 3. This invention uses a synchronization control module in the control system to monitor and adjust the lifting speed of all stepping hydraulic climbing devices in real time, ensuring that the first, second, and third template systems remain completely synchronized during the slipforming process. This effectively solves the problems of skewing and jamming caused by asynchrony in multi-hole templates, and ensures the relative positional accuracy of the gate shaft and ventilation shaft. It is particularly suitable for the construction of multi-hole vertical shafts in confined spaces and with complex structures.

[0031] 4. The gate slot forming system of this invention uses several forming units spliced ​​together. Each unit is connected to a pre-embedded reinforcing rod via an adjustable-length connecting rod. During the template sliding process, the track panel remains stationary, thereby directly forming a continuous and smooth gate slot track surface on the rising concrete surface. The adjustable length of the connecting rod allows for precise control of the position and verticality of the track panel, ensuring that the forming quality of the gate slot meets the requirements for gate embedded component installation, eliminating the cumbersome procedures of traditional second-stage concrete construction.

[0032] 5. The material feeding system of this invention features a buffer pipe with a closed bottom and open side walls at the end of the feeding steel pipe. Combined with the discharge hose and vibration device, this effectively reduces the impact velocity of concrete during high-drop feeding, preventing aggregate segregation. The discharge hose can swing flexibly to adapt to the uniform material distribution requirements of different areas in the multi-hole formwork system, improving pouring quality. The vibration device also assists in the smooth falling of concrete, preventing pipe blockage.

[0033] 6. This invention features an independent hanging basket-type operating platform beneath each template system, allowing operators to perform concrete surface construction, inspection, and other tasks within the platform, while maintaining a centralized control system. Compared to traditional full-span scaffolding construction, it eliminates the need for tall scaffolding erected in deep wells, reducing material transportation and scaffolding erection and dismantling work, significantly lowering the safety risks of falls from heights and falling objects, and improving the working environment.

[0034] In summary, this invention enables the one-time continuous pouring of the lining and gate slot of the multi-hole gate well. Compared with the traditional layered and block construction, it eliminates multiple processes such as formwork lifting, scaffolding erection and dismantling, and secondary concrete pouring, significantly improving construction efficiency. It is especially suitable for large-scale water conservancy and hydropower projects with high construction difficulty and tight schedules, such as pumped storage. Attached Figure Description

Detailed Implementation

[0046] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments, but the present invention is not limited to these embodiments.

[0047] Example 1

[0048] exist Figures 1-5 This invention relates to a device for simultaneous one-time casting and forming of a multi-hole gate well and gate slot. This device is used to simultaneously complete the concrete pouring of the gate well and two ventilation shafts, as well as the one-time forming of the gate slot, within the gate well chamber 1. In this embodiment, the ventilation shaft is formed; in practice, it could also be an inspection well, cable well, etc.

[0049] The equipment includes a template system, a template support system, a template slipform system, an auxiliary operating platform, a control system 12, a material feeding system 2, and a gate slot forming system. A casting space 3 is formed between the template system and the well wall of the gate chamber 1. The template system includes a first template system 4, a second template system 8, and a third template system 10. The first template system 4 is used to form the gate well, and its cross-section is rectangular. The second template system 8 and the third template system 10 are used to form the left ventilation well and the right ventilation well, respectively, and are symmetrically arranged on both sides of the first template system 4. The first template system 4, the second template system 8, and the third template system 10 are all steel templates, each including a steel template panel. A template support system is welded to the back of the template panel. In this embodiment, the template support system includes reinforcing ribs 5 distributed in a grid pattern. The reinforcing ribs 5 are made of angle steel or channel steel to enhance the overall rigidity and lateral pressure resistance of the template. The template support system has a manhole for operators to pass through.

[0050] The formwork slip system allows the formwork system to climb along the depth direction of the gate chamber 1. The formwork slip system includes a first slip device 7 and a second slip device 9. The formwork slip system also includes a synchronization control module, which is electrically connected to the control system 12. This module controls the lifting speed of all step-type hydraulic climbing devices 9-2 to maintain consistency, ensuring that the multi-hole formwork system rises synchronously during the slip process and preventing skewing. The first slip device 7 is located between the first formwork system 4 and the second formwork system 8, and also between the first formwork system 4 and the third formwork system 10. That is, multiple sets of first slip devices 7 are installed between the first formwork system 4 and the second formwork system 8, and between the third formwork system 10. The second slip device 9 is located at the other end of the first formwork system 4, the second formwork system 8, and the third formwork system 10, i.e., the end away from the first slip device 7, such as the outer end of each formwork system. In this embodiment, two sets of first sliding devices 7 are provided between the first template system 4 and the second template system 8, two sets of first sliding devices 7 are provided between the first template system 4 and the third template system 10, four sets of second sliding devices 9 are provided on the outside of the first template system 4, and two sets of second sliding devices 9 are provided on the outside of the second template system 8 and the third template system 10 respectively.

[0051] like Figure 8 , 9 As shown, the first slipform device 7 in this embodiment is composed of two second slipform devices 9 connected by a connecting plate 15. The second slipform device 9 includes a pre-embedded climbing rod 9-1, a stepping hydraulic climbing device 9-2, a steel plate 9-3, a stiffening plate 9-4, and a connecting channel steel 9-5. The pre-embedded climbing rod 9-1 is a steel round pipe, vertically installed in the poured concrete below the lintel of the multi-hole gate well, with its lower end anchored in the hardened concrete. The stepping hydraulic climbing device 9-2 is a through-type hydraulic jack, its center inserted through the pre-embedded climbing rod 9-1, allowing it to climb upwards along the rod. The base of the stepping hydraulic climbing device 9-2 is fixed to a steel plate 9-3. The steel plate 9-3 can slide up and down along the pre-embedded climbing rod 9-1. A connecting channel steel 9-5 is vertically welded to the lower surface of the end of the steel plate 9-3 away from the pre-embedded climbing rod 9-1. The lower end of the connecting channel steel 9-5 is fixedly connected to the upper crossbeam of the corresponding template system (first template system 4, second template system 8, or third template system 10). A triangular stiffening plate 9-4 is also provided between the steel plate 9-3 and the connecting channel steel 9-5 to enhance the connection strength. The stepping hydraulic climbing device 9-2 is controlled by a control system 12.

[0052] The control system 12 is mounted on the auxiliary operating platform. For example... Figure 6As shown, the auxiliary operating platform includes a first hanging basket 11, a second hanging basket 14, and a third hanging basket 13. These baskets are respectively positioned below the first template system 4, the second template system 8, and the third template system 10, serving to place operating tools and accommodate operators. The control system 12 is installed within the first hanging basket 11 for centralized control by the operator. The control system 12 includes a hydraulic pump station, a solenoid valve group, a programmable controller, and a control module linked to the synchronous control module.

[0053] The material feeding system 2 is located above the formwork system and is used to transport the concrete to the pouring space 3. For example... Figure 7 As shown, the feeding system 2 includes a feeding hopper 2-1, which is located at the wellhead of the gate chamber 1 and supplied with concrete by a concrete mixing plant. Several sections of feeding steel pipe 2-2 are connected to the lower part of the feeding hopper 2-1. Adjacent sections of feeding steel pipe 2-2 are detachably connected via connecting flanges 2-3, and the number of sections can be increased according to the well depth. To reduce the impact force and segregation of concrete during high-drop feeding, a buffer pipe 2-4 is connected to the end of the lowest section of the feeding steel pipe 2-2. The lower part of the buffer pipe 2-4 is closed, and its side wall is inclined with a discharge port. The discharge port is connected to a discharge hose 2-5 via a wire rope clamp. The discharge hose 2-5 is a rubber hose that can be manually swung to adjust the discharge position. The feeding system of this device also includes a vibration device, which is an attached vibrator installed on the outer wall of the feeding steel pipe 2-2 or the outer wall of the buffer pipe 2-4. It is activated intermittently during the feeding process to assist the concrete in falling smoothly and maintaining uniformity.

[0054] The gate slot forming system is located on both sides of the first template system 4, i.e., at the gate slot position of the gate well, and is used to form the gate well gate slot in one pour with the concrete of the gate well and ventilation shaft. For example... Figure 10 As shown, the gate slot forming system includes several forming units 6, which are sequentially spliced ​​along the height direction. Each forming unit 6 includes a track panel 6-4, which is a steel plate and serves as a sliding rail for the gate installation. A set of reinforcing I-beams 6-5 are vertically welded to each end of one side (back) of the track panel 6-4, with two I-beams in each set. Reinforcing plates 6-3 are welded to both the upper and lower ends of the reinforcing I-beams 6-5. Each reinforcing plate 6-3 is connected to a reinforcing rod 6-1 embedded in the poured concrete via at least two sets of connecting rods 6-2, used to fix and support the track panel 6-4. The reinforcing rod 6-1 is a pre-embedded steel bar or section steel, vertically anchored in the poured concrete below the lintel. The connecting rod 6-2 is an adjustable-length telescopic rod; in this embodiment, a pin-hole and pin-shaft connection is used to achieve rod extension and retraction, with both ends welded and fixed to the reinforcing plate 6-3 and the reinforcing rod 6-1, respectively. By adjusting the length of the connecting rod 6-2, the position and verticality of the track panel 6-4 can be precisely adjusted, thereby ensuring the forming accuracy of the door groove.
