Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a sliding formwork structure for an ultra-large irregular pressure regulating well. Background Technology

[0002] In large-scale water conservancy projects such as hydropower stations, surge tanks are a crucial component, regulating the head pressure of the turbine generator units to adapt to changes in power system load. Regarding hydraulic slipforming for the concrete lining of ultra-large, irregularly shaped surge tanks, there are reports on hydraulic slipforming for circular surge tanks, vertical surge tanks, and integrated hydraulic formwork for lining and diaphragm. However, the diameter of circular surge tanks is generally limited to around 30 meters, and the lining shape is relatively regular. Furthermore, there are currently no technologies or methods for using integrated slipforming for the gate well, gate slot, and main shaft lining in irregularly shaped surge tanks. Ultra-large, irregularly shaped surge tanks face numerous challenges during construction due to their complex structure and enormous size, especially the application of slipform construction technology. For ultra-large surge tanks with diameters exceeding 30 meters, the formwork truss beams need to have enormous load-bearing capacity. Traditional slipform structures and construction methods have the following problems when dealing with ultra-large, irregularly shaped surge tanks:

[0003] Poor structural adaptability: Traditional sliding formwork structures often struggle to adapt to changes in irregular structures, especially in ultra-large pressure regulating wells, where the complexity of the structure leads to insufficient adaptability and stability of the sliding formwork.

[0004] Low construction efficiency: Due to the special structure of the surge tank, the traditional slipform construction method consumes a lot of time in the assembly, lifting and positioning of the formwork, which affects the construction progress.

[0005] Safety issues: Ensuring the safety of personnel and equipment during the slipform construction of ultra-large irregular pressure regulating wells has become a major challenge, especially in high-altitude operations and complex environments.

[0006] Cost control: Traditional slipform structures and construction methods often require additional materials and labor when dealing with ultra-large and irregularly shaped pressure regulating wells, resulting in a significant increase in construction costs.

[0007] Therefore, existing technologies have shortcomings in terms of structural adaptability, construction efficiency, safety, and cost control in the slipform construction of ultra-large irregular pressure regulating wells, and need to be improved and innovated. Utility Model Content

[0008] This utility model does not address the shortcomings of existing technologies. Its purpose is to provide a slipform structure for ultra-large irregular pressure regulating wells. By adopting this solution, the template truss beam is divided into several truss beams and spliced ​​in sections, and then combined with each other to form a stable template truss beam. This not only improves construction efficiency but also provides huge load-bearing capacity to meet the needs of ultra-large pressure regulating wells.

[0009] This utility model is achieved through the following technical solution:

[0010] A sliding mold structure for an ultra-large irregular pressure regulating well includes:

[0011] The template truss beam includes a main truss beam, an irregular truss beam, a secondary truss beam, and a second transverse truss beam;

[0012] The cross-section of the main truss beam is arc-shaped and exceeds half a circle;

[0013] The second transverse truss beam is arranged radially along the main truss beam, and both ends are connected to the inner side of the main truss beam; a number of interconnected irregular truss beams are arranged on the side of the second transverse truss beam facing the gap of the main truss beam, and the number of irregular truss beams are arranged sequentially along the length direction of the second transverse truss beam and are all connected to the second transverse truss beam; each of the irregular truss beams is equipped with a cloud car.

[0014] The two outermost irregular truss beams are each connected to a secondary truss beam, and the two ends of the secondary truss beam are respectively connected to the ends of the main truss beam and the irregular truss beam;

[0015] The template truss beams are symmetrically arranged along a radial direction perpendicular to the second transverse truss beam.

[0016] Compared to existing technologies, for ultra-large surge tanks with diameters exceeding 30 meters, the template truss beams in the case of these massive surge tanks require enormous load-bearing capacity. Traditional slipform structures and construction methods suffer from poor structural adaptability, low construction efficiency, and safety issues when dealing with ultra-large, irregularly shaped surge tanks. This invention provides a slipform structure for ultra-large, irregularly shaped surge tanks. This solution divides the template truss beams into several segments, splices them together, and combines them to form a stable template truss beam. This improves construction efficiency while providing enormous load-bearing capacity, meeting the requirements of ultra-large surge tanks. The specific design includes an arc-shaped main truss beam, which is located on the outermost side and connects to the external cast-in-place concrete wall. The arc shape of the main truss beam adapts to the circumferential sidewalls of the large surge tank, improving structural stability. The main truss beam is an arc exceeding half its length, but with a notch to facilitate the installation of other truss beams within the notch. A second transverse truss beam is provided radially on the main truss beam to improve structural stability and facilitate the installation and fixing of other truss beams. Furthermore, to meet the transportation capacity of the ultra-large surge tank and enhance its transportation capacity, three irregular truss beams are provided. Three cloud carts are installed at the front end of each of the three irregular truss beams. The three cloud carts are based on the three aforementioned irregular truss beams, improving their stability and transportation efficiency. All the irregular truss beams that mount the cloud car are connected to the second horizontal truss beam. Since the irregular truss beams have cloud cars, secondary truss beams also need to be set up. The secondary truss beams are connected to the irregular truss beams, and then the irregular truss beams are connected to the ends of the main truss beams to improve the stability of the irregular truss beams.

[0017] To facilitate adaptation to the circular assembly surface, three irregularly shaped truss beams are installed inside the template truss beam, with adjacent irregularly shaped truss beams forming an angle with each other. The irregularly shaped truss beams are rectangular; the three irregularly shaped truss beams are adjacent and arranged at a 40° angle.

[0018] To improve connection strength and provide space for installing irregularly shaped truss beams, the secondary truss beam is L-shaped, with its apex connected to the second horizontal truss beam. In this design, the secondary truss beam is L-shaped, with one end connected to the end of the main truss beam and the other end connected to the main truss beam, while its apex is connected to the second horizontal truss beam. This three-point connection further enhances structural stability. Additionally, the sides of the secondary truss beam are inclined, providing sufficient installation space within the notch for installing irregularly shaped truss beams.

[0019] To connect several irregularly shaped truss beams into a single unit, the template truss beam further includes a first horizontal truss beam, which is parallel to the second horizontal truss beam and sequentially connected to several irregularly shaped truss beams. Both ends of the first horizontal truss beam are respectively connected to the end connections of two secondary truss beams on the irregularly shaped truss beams. Specifically, both ends of the first horizontal truss beam are fixedly connected to the outer corners of the irregularly shaped truss beams located on both sides. The second horizontal truss beam is arranged along the diameter of the template truss beam and parallel to the first horizontal truss beam.

[0020] To improve the structural stability of several irregular truss beams, several vertical trusses are sequentially connected between the first and second horizontal trusses. These vertical trusses are arranged in an array along the length of the first horizontal truss beam and are perpendicular to the first horizontal truss beam.

[0021] To improve the overall structural stability, the template truss beam also includes a third horizontal truss beam and a fourth horizontal truss beam. The third horizontal truss beam and the fourth horizontal truss beam are both located on the side of the second horizontal truss beam facing the main truss beam and are parallel to each other. The two ends of the third horizontal truss beam and the fourth horizontal truss beam are respectively connected to the inner side of the main truss beam and the second horizontal truss beam. The third horizontal truss beam and the fourth horizontal truss beam are symmetrically arranged along the radial direction of the main truss beam perpendicular to the second horizontal truss beam.

[0022] To fill the gap in the main truss beam after installing all the truss beams within the gap to form a circular template truss beam, an arc-shaped truss beam is also included. The arc-shaped truss beam has an arc that matches the curvature of the main truss beam, and both ends of the arc-shaped truss beam are respectively connected to both ends of the main truss beam.

[0023] The main truss beam, irregular truss beam, secondary truss beam, first horizontal truss beam, second horizontal truss beam, third horizontal truss beam, fourth horizontal truss beam, arc-shaped truss beam, and vertical truss beam mentioned above are all welded and fixed with equilateral angle steel.

[0024] As a method of implementing slipform, the template truss beam is provided with a cast-in-place concrete wall on the outer side of the circumference. A slipform template is provided at the intersection of the template truss beam and the cast-in-place concrete wall. A slipform assembly is slidably connected to the slipform template, and the slipform assembly is connected to the template truss beam.

[0025] Along the circumference of the cast concrete wall, a plurality of lifting components are evenly distributed on the surface of the cast concrete wall, and the plurality of lifting components are used to drive the sliding formwork component to lift.

[0026] As a specific implementation of the lifting method, the lifting assembly includes a support rod connected to the cast concrete wall, the upper end of the support rod is provided with a through-type jack, and the lower end of the support rod passes through the interior of the cast concrete wall;

[0027] The bottom end of the through-hole jack is provided with a frame, which is connected to the template truss beam; the through-hole jack is used to drive the frame to lift.

[0028] To protect the standing operator, the slipform assembly includes two auxiliary hanging hooks connected to the template truss beam. The two auxiliary hanging hooks are located on both sides, and an auxiliary plate is provided between the lower ends of the two auxiliary hanging hooks.

[0029] Both ends of the auxiliary hanging plate hook are provided with hooks. The hook at the upper end of the auxiliary hanging plate hook bends outward and connects to the template truss beam, while the hook at the lower end of the auxiliary hanging plate hook bends inward and is used to connect to the auxiliary plate.

[0030] The inner wall of the auxiliary hanging plate hook is provided with several safety railings along its length.

[0031] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0032] 1. High Load-Bearing Capacity: By dividing the formwork truss beam into several segments and splicing them together to form a stable formwork truss beam, construction efficiency is improved while providing enormous load-bearing capacity to meet the needs of ultra-large surge tanks. The main truss beam, irregular truss beam, secondary truss beam, first horizontal truss beam, second horizontal truss beam, third horizontal truss beam, fourth horizontal truss beam, and vertical truss beam are all constructed using equilateral angle steel welded and fixed. This slipform mechanism provides the load-bearing capacity for ultra-large surge tanks, making this structure even stronger.

[0033] 2. High stability: Equipped with an aligner and an alignment plate, the aligner emits an alignment line that illuminates the surface of the alignment plate. During the sliding formwork lifting process, the aligner and alignment plate can be used to determine whether the lifting distances of the lifting components on both sides are the same, thus avoiding errors. Moreover, the modular design of the sliding formwork structure can flexibly adapt to the complex structure of ultra-large irregular pressure regulating wells, significantly improving the flexibility of construction and the stability of the structure, thereby enhancing the adaptability of the structure.

[0034] 3. High safety: Through pre-assembly technology and through-hole jacks, the vertical lifting of the slipform is ensured to be stable and safe, avoiding structural swaying that may be caused by traditional lifting methods. This significantly reduces the amount of high-altitude work, improves the efficiency and safety of slipform lifting, speeds up the construction progress, reduces additional material and labor costs, effectively controls construction costs, improves the overall economic benefits of the project, and enhances construction efficiency.

Detailed Implementation

[0045] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0046] Example 1:

[0047] This embodiment 1 provides a sliding mold structure for an ultra-large irregular pressure regulating well, such as Figure 1 and Figure 2 As shown, it includes:

[0048] Template truss beam 1, wherein template truss beam 1 includes main truss beam 14, irregular truss beam 15, secondary truss beam 16, and second transverse truss beam 18;

[0049] The cross-section of the main truss beam 14 is arc-shaped and exceeds half a circle;

[0050] The second transverse truss beam 18 is radially arranged along the main truss beam 14, and both ends are connected to the inner side of the main truss beam 14; a plurality of interconnected irregular truss beams 15 are arranged on the side of the second transverse truss beam 18 facing the notch of the main truss beam 14, and the plurality of irregular truss beams 15 are arranged sequentially along the length direction of the second transverse truss beam 18, and are all connected to the second transverse truss beam 18; each irregular truss beam 15 is equipped with a cloud cart;

[0051] The two outermost irregular truss beams 15 are each connected to a secondary truss beam 16, and the two ends of the secondary truss beam 16 are respectively connected to the ends of the main truss beam 14 and the irregular truss beam 15.

[0052] The template truss beam 1 is symmetrically arranged along the radial direction perpendicular to the second transverse truss beam 18.

[0053] Compared to existing technologies, for ultra-large surge tanks with diameters exceeding 30 meters, the template truss beam 1 needs to have enormous load-bearing capacity. Traditional slipform structures and construction methods suffer from poor structural adaptability, low construction efficiency, and safety issues when dealing with ultra-large irregular surge tanks. This invention provides a slipform structure for ultra-large irregular surge tanks. By dividing the template truss beam 1 into several truss beams and splicing them in segments, and combining them to form a stable template truss beam 1, the construction efficiency is improved while providing enormous load-bearing capacity to meet the needs of ultra-large surge tanks. The specific design includes an arc-shaped main truss beam 14, which is located on the outermost side and connected to the external cast-in-place concrete wall 4. The main truss beam 14 is arc-shaped to adapt to the circumferential sidewall of the large surge tank, improving structural stability. The main truss beam 14 is an arc exceeding half its length, but with a notch to facilitate the installation of other truss beams within the notch. A second transverse truss beam 18 is provided radially on the main truss beam 14 to improve structural stability and facilitate the installation and fixing of other truss beams. Furthermore, to meet the transportation capacity of the ultra-large surge tank and improve its transportation capacity, three irregular truss beams are provided. Three cloud carts are installed at the front end of each of the three irregular truss beams. The three cloud carts are based on the three irregular truss beams, improving their stability and transportation efficiency. All the irregular truss beams that mount the cloud car are connected to the second horizontal truss beam 18. Since the irregular truss beam has the cloud car, a secondary truss beam 16 is also required. The secondary truss beam 16 is connected to the irregular truss beam, and then the irregular truss beam is connected to the end of the main truss beam 14 to improve the stability of the irregular truss beam.

[0054] To facilitate adaptation to the circular assembly surface, three irregularly shaped truss beams 15 are installed inside the template truss beam 1, with adjacent irregularly shaped truss beams 15 forming an angle with each other. The irregularly shaped truss beams are rectangular; the three irregularly shaped truss beams are adjacent and arranged at a 40° angle.

[0055] To improve connection strength and provide space for installing irregular truss beams, the secondary truss beam 16 is L-shaped, with its apex connected to the second transverse truss beam 18. In this design, the secondary truss beam 16 is L-shaped, with one end connected to the end of the main truss beam 14 and the other end connected to the main truss beam 14, while its apex is connected to the second transverse truss beam 18. This fixation at three connection points further improves the stability of the structure. Additionally, the side of the secondary truss beam 16 is inclined, thus providing sufficient installation space within the notch for installing irregular truss beams.

[0056] To connect several irregularly shaped truss beams 15 into a single unit, the template truss beam 1 further includes a first horizontal truss beam 17, which is parallel to the second horizontal truss beam 18 and sequentially connected to several irregularly shaped truss beams 15. Both ends of the first horizontal truss beam 17 are respectively connected to the end connections of two secondary truss beams 16 on the irregularly shaped truss beams 15. Specifically, both ends of the first horizontal truss beam 17 are fixedly connected to the outer corners of the irregularly shaped truss beams located on both sides; the second horizontal truss beam 18 is arranged along the diameter of the template truss beam 1 and parallel to the first horizontal truss beam 17.

[0057] To improve the structural stability of the irregular truss beams 15, a number of vertical trusses 19 are connected sequentially between the first horizontal truss beam 17 and the second horizontal truss beam 18. The vertical trusses 19 are arranged in an array along the length of the first horizontal truss beam 17 and are perpendicular to the first horizontal truss beam 17.

[0058] To improve the overall structural stability, the template truss beam 1 further includes a third horizontal truss beam 20 and a fourth horizontal truss beam 21. The third horizontal truss beam 20 and the fourth horizontal truss beam 21 are both located on the side of the second horizontal truss beam 18 facing the main truss beam 14 and are parallel to each other. The two ends of the third horizontal truss beam 20 and the fourth horizontal truss beam 21 are respectively connected to the inner side of the main truss beam 14 and the second horizontal truss beam 18. The third horizontal truss beam 20 and the fourth horizontal truss beam 21 are symmetrically arranged along the radial direction of the main truss beam 14 perpendicular to the second horizontal truss beam 18.

[0059] To fill the gap in the main truss beam 14 after all truss beams are installed in the gap to form a circular template truss beam 1, an arc-shaped truss beam 22 is also included. The arc-shaped truss beam 22 is adapted to the curvature of the main truss beam 14, and the two ends of the arc-shaped truss beam 22 are respectively connected to the two ends of the main truss beam 14.

[0060] The main truss beam 14, the irregular truss beam, the secondary truss beam 16, the first horizontal truss beam 17, the second horizontal truss beam 18, the third horizontal truss beam 20, the fourth horizontal truss beam 21, the arc-shaped truss beam 22, and the vertical truss beam 19 mentioned above are all welded and fixed with equilateral angle steel.

[0061] Example 2:

[0062] This embodiment 2 is a further optimization based on embodiment 1, such as... Figures 3-7As shown, a slipform lifting method is provided. First, on a flat surface at the construction site, slipform template 3 is pre-assembled according to the design drawings of the surge tank. Based on the irregular structure of the surge tank, suitable geometric template modules are selected and assembled to form a slipform structure that fits snugly against the well wall. Using a through-hole jack 7, the pre-assembled slipform structure is vertically lifted to the surge tank opening. An automated monitoring system monitors the stress, deformation, and position of the slipform structure in real time to ensure a smooth and safe lifting process. After the slipform assembly 5 is lifted to the predetermined position, the position of the slipform structure is gradually adjusted based on data feedback from the automated monitoring system to ensure precise positioning.

[0063] The specific structure includes a template truss beam 1 and a cast concrete wall 4 set around the template truss beam 1. A slipform template 3 is provided at the intersection of the template truss beam 1 and the cast concrete wall 4.

[0064] Among them, the surface of the poured concrete wall 4 is equipped with a lifting component 2, and the lower part of the template truss beam 1 is equipped with a sliding formwork component 5 at the intersection of the sliding formwork 3. The lifting component 2 is used to drive the sliding formwork component 5 to be lifted on the surface of the sliding formwork 3. The lifting is carried out through pre-assembly technology and through-hole jack 7. The vertical lifting of the sliding formwork component 5 is carried out by through-hole jack 7 to ensure the stability and safety of the lifting process, avoid the structural shaking that may be caused by traditional lifting methods, significantly reduce the amount of high-altitude work, improve the efficiency and safety of lifting the sliding formwork component 5, and can flexibly adapt to the complex structure of the ultra-large irregular pressure regulating well, significantly improving the flexibility of construction and the stability of the structure.

[0065] Furthermore, there are two lifting components 2. The surfaces of the two lifting components 2 are respectively provided with an aligner 12 and an alignment plate 13. When the lifting components 2 are lifted, the aligner 12 and the alignment plate 13 are aligned with each other to determine the lifting distance of the two lifting components 2. The aligner 12 and the alignment plate 13 are provided, and the aligner 12 emits an alignment line that shines on the surface of the alignment plate 13. When the sliding mold structure is lifted, the aligner 12 and the alignment plate 13 can be used to determine whether the lifting distance of the two lifting components is the same during the sliding mold lifting process, so as to avoid the problem of error. The surface of the alignment plate 13 is provided with several alignment lines, and the determination is made by judging the position of the alignment line illuminated by the aligner 12.

[0066] The lifting component 2 includes a support rod 7 connected to the poured concrete wall 4, and a through-type jack 6 is provided at the top of the support rod 7;

[0067] Among them, the through-hole jack 6 operates and lifts around the support rod 7 as the axis. The support rod 7 passes through the inside of the poured concrete wall 4 and is embedded inside the poured concrete wall 4. In this way, the through-hole jack 7 and the support rod 7 are connected in a through-hole manner, and the lifting is carried out under the operation of the through-hole jack 7.

[0068] Among them, the through-hole type jack 7 is a double-acting jack that uses a double hydraulic cylinder to tension the prestressing tendons and a top-pressure anchor. Its working principle is as follows: When tensioning the prestressing tendons, the tensioning cylinder nozzle enters oil and the top-pressure cylinder nozzle returns oil. The top-pressure cylinder, connecting sleeve, and support sleeve are connected as a whole and move to the right to press against the anchor ring. The tensioning cylinder, end cap nut, plug, and through-hole sleeve are connected as a whole to drive the tool anchor to move to the left to tension the prestressing tendons. When top-pressure anchoring, under the condition of maintaining stable tension force, the top-pressure cylinder nozzle enters oil, and the top-pressure piston, protective sleeve, and top-pressure head are connected as a whole and move to the right to forcefully push the wedge into the anchor ring. At this time, the tensioning cylinder nozzle returns oil, the top-pressure cylinder nozzle enters oil, and the tensioning cylinder hydraulically returns. Finally, the tensioning cylinder and the top-pressure cylinder nozzle return oil at the same time, and the top-pressure piston returns to its original position under the action of spring force.

[0069] The bottom of the through-hole jack 7 is equipped with a frame 8, which is an L-shaped structure. One end of the frame 8 is connected to the template truss beam 1, and the other end of the frame 8 is connected to the through-hole jack 7. When the through-hole jack 7 runs, it drives the frame 8 to lift. One end of the frame 8 is connected to the template truss beam 1.

[0070] The slipform assembly 5 includes an auxiliary disk hook 11 connected to the template truss beam 1. The bottom end of the auxiliary disk hook 11 is provided with an auxiliary disk 9, which is connected to the auxiliary disk hook 11.

[0071] The auxiliary plate hook 11 is equipped with several safety railings 10 on its inner side. With the setting of the safety railings 10, the operator can stand inside the sliding mold assembly 5 and be protected by the safety railings 10 to avoid safety accidents caused by falling during the lifting process.

[0072] The auxiliary plate hook 11 has hooks at both ends. The auxiliary plate hook 11 is connected to the auxiliary plate 9 at the bottom and the template truss beam 1 at the top through the hooks at both ends, so that the sliding formwork assembly 5 is stably connected to the template truss beam 1.

[0073] By adopting the above technical solution:

[0074] By using pre-assembly technology and through-hole jacks 7 for vertical lifting of the slipform assembly 5, the lifting process is made stable and safe, avoiding structural swaying that may be caused by traditional lifting methods. This significantly reduces the amount of high-altitude work, improves the efficiency and safety of lifting the slipform assembly 5, and can flexibly adapt to the complex structure of ultra-large irregular pressure regulating wells, significantly improving the flexibility of construction and the stability of the structure.

[0075] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
