Technical Field

[0001] This application relates to the field of dam panel manufacturing technology, and in particular to a slipform device and its usage method. Background Technology

[0002] A dam panel is a concrete panel laid on the surface of a reservoir dam to serve as a water barrier and prevent seepage.

[0003] Slipforming systems are typically used in the fabrication of dam panels. A slipforming system is a device that allows concrete to be continuously poured and shaped onto the dam surface by sliding along it. Specifically, the slipforming system includes a template and a traction component. The template has through-holes for pouring concrete, which is poured through the template into the cavity between the template and the dam surface. As the traction component pulls the template along, the continuous pouring and shaping of the dam panel is achieved.

[0004] However, the thickness of the dam panels is fixed during the current manufacturing process, which limits their applicability. Summary of the Invention

[0005] The purpose of this application is to provide a slipform device and its usage method, which aims to solve the problem of poor applicability caused by the fixed thickness of dam panels during manufacturing.

The template is provided with a pouring hole that communicates with the pouring space so that concrete can be poured into the pouring space through the pouring hole and solidified to form the dam panel. The template can be moved along the height direction of the slide rail base to adjust the thickness of the pouring space.

[0007] In some embodiments, the second slide rail is slidably disposed on top of the first slide rail, and the template is connected to the top of the second slide rail.

[0008] In some embodiments, the first slide rail is disposed on the slide rail base and can move relative to the slide rail base along the height direction of the slide rail base, so as to link the template through the second slide rail.

[0009] In some embodiments, the slide rail base is provided with a threaded hole, and a threaded adjusting member connected to the first slide rail passes through the threaded hole. The threaded adjusting member is threadedly engaged with the threaded hole, and the axial direction of the threaded adjusting member is parallel to the height direction of the slide rail base.

[0010] In some embodiments, the slide rail base is provided with a mounting groove with a top opening, the first slide rail is disposed in the mounting groove, a sliding cavity is formed between the first slide rail and the top opening, and the second slide rail is rotatably disposed in the sliding cavity; the template is disposed outside the mounting groove and is connected to the second slide rail through the top opening.

[0011] In some embodiments, the second slide rail is connected to the template by a riveting member.

[0012] In some embodiments, a rolling element is provided between the first slide rail and the second slide rail.

[0013] In some embodiments, a pulling member is provided on one side of the second slide rail, and the pulling member can drive the second slide rail to move along the length direction of the second slide rail under the action of external force.

[0015] Secondly, embodiments of this application also provide a method for using a sliding mold device, including: Two sliding rail bases are set at intervals on the dam surface of the dam body; By moving the template along the height direction of the slide rail base, the thickness of the pouring space is adjusted to match the thickness of the dam panel to be produced. Concrete is poured into the pouring space formed between the template and the dam surface through the pouring holes on the template; After the concrete has solidified, the second slide rail is moved along its length to carry out continuous pouring operations, ultimately forming a complete dam panel.

[0016] The beneficial effects of this invention are: This application provides a slipform device and its usage method. The slipform device includes two slide rail bases, two first slide rails, two second slide rails, and a template. The two slide rail bases are positioned relatively apart on the dam face of the dam body. The two first slide rails are respectively mounted on their corresponding slide rail bases, and the two second slide rails are in rolling engagement with the two first slide rails. The template is connected to the two second slide rails, forming a pouring space between the template and the dam face. The template is provided with pouring holes communicating with the pouring space, allowing concrete to be poured into the pouring space through the pouring holes and solidify to form the dam panel. In this application, the template can move along the height direction of the slide rail bases to adjust the thickness of the pouring space. This allows for flexible adjustment of the distance between the template and the dam face according to the design requirements of the dam panel, thereby achieving free adjustment of the thickness of the pouring space. Consequently, the thickness of the final dam panel cast within the pouring space can be changed, improving the overall applicability of the slipform device. Attached Figure Description

Thus, a feature defined with "first," "second," "third," "fourth," "fifth," and "sixth" may explicitly or implicitly include one or more of that feature.

[0021] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0022] Reference Figures 1 to 3 As shown, this embodiment provides a sliding mold device, including two slide rail bases 100, two first slide rails 200, two second slide rails 300, and a template 400.

[0023] Two sliding rail bases 100 are used to be relatively spaced on the dam face of the dam body; two first sliding rails 200 are respectively set on the corresponding sliding rail bases 100; two second sliding rails 300 are respectively in rolling engagement with the two first sliding rails 200; the template 400 is respectively connected to the two second sliding rails 300, and a pouring space 410 is formed between the template 400 and the dam face. The template 400 is provided with a pouring hole 420 communicating with the pouring space 410, so that concrete can be poured into the pouring space 410 through the pouring hole 420 and solidified to form the dam panel; the template 400 can be extended along the height direction of the sliding rail base 100 (refer to...). Figure 1 The z-direction (as shown) is moved to adjust the thickness of the pouring space 410.

[0024] In practice, the two sliding rail bases 100 serve as the load-bearing foundation components of the sliding formwork device. During construction, they are installed at predetermined positions on the dam surface using a relatively spaced arrangement. The sliding rail bases 100 are constructed entirely of high-strength steel, possessing characteristics of high load-bearing capacity, deformation resistance, and corrosion resistance. They can withstand the self-weight of the formwork 400 and the impact loads during the sliding process for extended periods.

[0025] Furthermore, two first slide rails 200 are installed one-to-one on two slide rail bases 100, and two second slide rails 300 form a rolling fit structure with their corresponding first slide rails 200. Compared with the traditional sliding friction structure, the rolling fit method significantly reduces the frictional resistance between the first slide rails 200 and the second slide rails 300, allowing the template 400 to move along the length direction of the second slide rail 300 (refer to...). Figure 1 The template 400 slides smoothly in the x-direction shown. In this embodiment, the second slide rail 300 corresponds one-to-one with the first slide rail 200 and is paired and matched. The structure design of synchronous sliding on both sides can ensure that the two ends of the template 400 are subjected to uniform force and synchronous lifting, thereby effectively avoiding the phenomenon of one-sided jamming or tilting of the template 400.

[0026] Template 400 serves as the forming mold for the dam panel, with its left and right ends rigidly connected to two second slide rails 300, respectively. The template 400 and the existing dam surface enclose a closed pouring space 410, which is a cavity for the solidified concrete. Its thickness and shape directly determine the forming dimensions and appearance quality of the dam panel. For example, template 400 can be as follows: Figure 1 The plate-like structure shown. Template 400 can specifically be a steel template or an alloy template.

[0027] To meet the requirements of concrete pouring operations, a through-hole 420 is provided on the formwork 400, which is fully connected to the inner pouring space 410. During construction, liquid concrete can be continuously and evenly injected into the pouring space 410 between the formwork 400 and the dam surface through the pouring hole 420. After the concrete is vibrated and compacted and naturally cured, a flat and regular dam protection panel can be formed.

[0028] For example, multiple pouring holes 420 can be arranged in an array to improve the efficiency of concrete injection.

[0029] In this embodiment, the template 400 can move along the height direction of the slide rail base 100 to adjust the thickness of the casting space 410. This allows for flexible adjustment of the vertical distance between the template 400 and the dam surface according to the design requirements of the dam panel, thereby enabling free adjustment of the thickness of the casting space 410. This changes the thickness of the dam panel that is ultimately cast in the casting space 410, thus improving the applicability of the entire slipform device.

[0030] Reference Figures 1 to 3 As shown, in some embodiments, the second slide rail 300 is slidably disposed on top of the first slide rail 200, and the template 400 is connected to the top of the second slide rail 300.

[0031] In practice, the second slide rail 300 adopts a top-mounted rolling assembly structure, directly rolling on top of the first slide rail 200, forming a rolling fit between the two. The template 400 is horizontally mounted on the top end face of the second slide rail 300, forming a stable connection with the top platform of the second slide rail 300, realizing a hierarchical assembly layout of the template 400, the second slide rail 300, and the first slide rail 200 from top to bottom.

[0032] This layout allows the pouring load and self-weight of the formwork 400 to be directly and vertically transferred to the second slide rail 300, and then evenly transferred to the first slide rail 200 and the bottom slide rail base 100 via the second slide rail 300. The entire load transfer path is straight and the force is evenly distributed. At the same time, the top-mounted rolling structure can significantly reduce the probability of jamming during the horizontal sliding process of the second slide rail 300 relative to the first slide rail 200.

[0033] Reference Figures 1 to 3 As shown, in some embodiments, the first slide rail 200 is disposed on the slide rail base 100 and can move relative to the slide rail base 100 along the height direction of the slide rail base 100, so as to link the template 400 through the second slide rail 300.

[0034] In practice, the first slide rail 200 serves as an intermediate transmission component, forming a linkage structure with the upper second slide rail 300 and the template 400. When the first slide rail 200 is adjusted vertically, it can simultaneously drive the second slide rail 300 and the overall template 400 to move synchronously, so as to meet the production requirements of different elevations and different thicknesses of the dam panels.

[0035] Reference Figures 1 to 3 As shown, in some embodiments, the slide rail base 100 is provided with a threaded hole 110, and a threaded adjusting member 120 connected to the first slide rail 200 is inserted into the threaded hole 110. The threaded adjusting member 120 is threadedly engaged with the threaded hole 110, and the axial direction of the threaded adjusting member 120 is parallel to the height direction of the slide rail base 100.

[0036] In practice, to achieve precise vertical adjustment of the first slide rail 200, a vertically arranged threaded hole 110 is provided on the slide rail base 100. The opening axis of the threaded hole 110 is parallel to the height direction of the slide rail base 100. A threaded adjusting component 120 passes through the threaded hole 110, and the bottom end of the threaded adjusting component 120 is threadedly connected to the first slide rail 200. The threaded adjusting component 120 and the threaded hole 110 form a high-precision threaded pair. Relying on the helical transmission principle of the thread, by rotating the threaded adjusting component 120 in the forward or reverse direction, the rotational motion can be converted into the vertical linear motion of the first slide rail 200, thus precisely controlling the lifting height of the first slide rail 200.

[0037] Meanwhile, the threaded adjustment component 120 has a self-locking function. After adjustment, it can be locked in position by relying on the thread engagement friction force. No additional positioning and fixing components are required. It can effectively prevent the first slide rail 200 and template 400 from shifting under the action of pouring load, and ensure the stability of the thickness dimension of the pouring space 410. The entire adjustment operation has high adjustment accuracy, good locking effect and convenient operation.

[0038] For example, the threaded adjusting element 120 may be an adjusting screw or an adjusting bolt. An adjusting nut 130 may be provided at the top of the threaded adjusting element 120 to allow the operator to rotate the adjusting screw.

[0039] Reference Figures 1 to 3 As shown, in some embodiments, the slide rail base 100 is provided with a mounting groove 150 with a top opening 140, the first slide rail 200 is disposed in the mounting groove 150, a sliding cavity 160 is formed between the first slide rail 200 and the top opening 140, and the second slide rail 300 is rotatably disposed in the sliding cavity 160; the template 400 is disposed outside the mounting groove 150 and is connected to the second slide rail 300 through the top opening 140.

[0040] In a specific implementation, the slide rail base 100 is provided with a mounting groove 150 with a top opening 140. The first slide rail 200 is nested inside the mounting groove 150. The side wall of the mounting groove 150 can form a horizontal limiting constraint on the first slide rail 200 to prevent the first slide rail 200 from horizontally swaying or shifting.

[0041] Furthermore, a sliding cavity 160 is formed between the upper surface of the first slide rail 200 and the top opening 140 of the mounting groove 150. The second slide rail 300 is integrally embedded inside the sliding cavity 160 and can slide freely along the length of the second slide rail 300. The template 400 is integrally arranged outside the mounting groove 150 of the slide rail base 100, and the top surface of the second slide rail 300 can be fixedly connected to the template 400 through the top opening 140. This structural design can effectively prevent concrete debris and dust from entering the sliding mating surfaces of the first slide rail 200 and the second slide rail 300, avoiding jamming and wear of the second slide rail 300.

[0042] Reference Figures 1 to 3 As shown, in some embodiments, the second slide rail 300 is connected to the template 400 by a riveting member 500.

[0043] Specifically, during construction and assembly, a specialized riveting device is used to connect the riveted parts 500 to the second slide rail 300 and the formwork 400, achieving a riveted connection between the two. This riveting connection method features strong structural integrity, vibration resistance, fatigue resistance, and resistance to loosening. Under conditions of long-term lifting and sliding of the formwork 400, concrete vibration, and lateral pressure impact during pouring, it maintains a tight connection at all times. It avoids problems such as bolt loosening (common with bolted connections) or weld cracking (common with welded connections), effectively ensuring the synchronous movement accuracy of the formwork 400 and the second slide rail 300, preventing deviations in the dam panel forming caused by connection gaps. Furthermore, the riveting construction is convenient, assembly efficiency is high, and the equipment has low maintenance costs.

[0044] For example, multiple rivets 500 can be provided at circumferential intervals along the template 400 to improve the connection stability between the template 400 and the second slide rail 300.

[0045] Reference Figures 1 to 3 As shown, in some embodiments, a rolling element 600 is provided between the first slide rail 200 and the second slide rail 300 to achieve rolling cooperation between the two. After the dam panel at a certain position is formed, the template 400 can be moved by pulling the second slide rail 300 to achieve continuous pouring operation and finally form the completed dam panel.

[0046] For example, the rolling element 600 can be a low-friction rolling component such as a ball, roller, or a shaft, evenly distributed in the sliding contact area. This completely converts the surface friction between the first slide rail 200 and the second slide rail 300 into point contact or line contact rolling friction, minimizing the coefficient of sliding friction. This structure not only significantly reduces the running resistance of the second slide rail 300 during sliding, but also reduces the wear rate between the contact surfaces of the first slide rail 200 and the second slide rail 300, effectively extending the service life of the first slide rail 200 and the second slide rail 300, thereby improving the operational stability of the sliding mold device.

[0047] Reference Figures 1 to 3 As shown, in some embodiments, a pulling member 700 is provided on one side of the second slide rail 300, and the pulling member 700 can drive the second slide rail 300 to move along the length direction of the second slide rail 300 under the action of external force.

[0048] In practice, a pulling member 700 is fixedly installed on the outer end face of the second slide rail 300. The pulling member 700 can be adapted to various external force driving methods such as manual traction, electric traction, and hydraulic traction. The force direction of the pulling member 700 is consistent with the length direction of the second slide rail 300. Under the action of external force traction, it can accurately drive the second slide rail 300 along its own length direction (refer to...). Figure 1The template 400 makes a horizontal sliding motion in the x direction shown, which simultaneously drives the template 400 to make fine adjustments to its horizontal position and switch positions. Therefore, there is no need to disassemble and assemble the entire slipform device. The template 400 can be moved horizontally by pulling the puller 700, and the pouring position can be quickly switched. This is suitable for the construction needs of large-area, long-distance continuous panel pouring of dams and greatly improves the continuity of construction.

[0049] For example, the pull element 700 can be a lever or a handle.

[0050] For example, the pull member 700 may be welded or screwed to the second slide rail 300.

[0051] In some embodiments, the slide rail base 100 is slidably disposed on the dam surface. For example, a sliding fit can be achieved by using rollers or pulleys.

[0052] In this embodiment, the slide rail base 100 is not fixed to the dam surface, but is arranged on the dam surface of the dam body by means of rollers or pulleys, so that the horizontal displacement of the entire slipform device can be realized to achieve continuous pouring operation of large-area dam panels.

[0053] Reference Figure 4 As shown, this embodiment provides a method for using a sliding mold device, including: Step S1: Set two sliding rail bases 100 at a relative interval on the dam surface of the dam body; Step S2: By moving the template 400 along the height direction of the slide rail base 100, the thickness of the pouring space 410 is adjusted to match the thickness of the dam panel to be produced. Step S3: Pour concrete into the pouring space 410 formed between the template 400 and the dam surface through the pouring hole 420 on the template 400. Step S4: After the concrete has solidified, move the second slide rail 300 along its length to carry out continuous pouring operations, ultimately forming a complete dam panel.

[0054] The specific structure and implementation principle of the sliding formwork device in this embodiment are the same as those of the sliding formwork device provided in the above embodiments, and can bring the same or similar technical effects. They will not be described in detail here, but can be referred to the description of the above embodiments.

[0055] The specific usage method is as follows: In step S1, in the early stage of construction, the dam face pouring construction area is determined according to the dam face construction design drawings, and two sliding rail bases 100 are arranged at relative intervals on the dam face construction position according to the preset spacing and parallelism requirements.

[0056] In step S2, based on the design thickness parameters of the dam panel to be constructed, the thickness adjustment process of the pouring space 410 is initiated. By moving the template 400, the thickness of the pouring space 410 formed by the template 400 and the dam surface is precisely adjusted so that the thickness of the pouring space 410 perfectly matches the design panel thickness.

[0057] In step S3, after the thickness of the pouring space 410 is adjusted and fixed, the concrete pouring process is started. The well-mixed and qualified concrete material is continuously and evenly poured into the pouring space 410 between the template 400 and the dam surface through the pre-set pouring hole 420 of the template 400.

[0058] In step S3, after the concrete in the current pouring space 410 has initially solidified and reached its molding strength, there is no need to disassemble the formwork 400 and the slide rail base 100. By applying external force, the second slide rail 300 is pulled, causing it to slide smoothly along its own length, simultaneously driving the formwork 400 to complete the horizontal position switch, so that the formwork 400 moves to the next area to be poured, forming a new closed pouring space 410.

[0059] Repeat the above pouring operation to gradually complete the concrete pouring of the entire dam surface, and finally form a complete dam panel that is continuous, without segmented joints, and with uniform size.

[0060] In the description of the embodiments of this application, specific features, structures, materials or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0061] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
