Description

Technical Field

[0001] This utility model belongs to the field of slope protection construction technology, specifically relating to a hydraulic slipform device for high and steep slope construction. Background Technology

[0002] To facilitate concrete pouring on steep slopes, formwork is usually erected to shape the concrete; however, the formwork may float during concrete pouring, which can easily cause concrete leakage or even formwork collapse.

[0003] Currently, there are two main methods to address the problem of formwork floating, but both have drawbacks. One method is to add counterweights to the formwork to prevent it from floating. However, as the slope increases, the required counterweight also gradually increases. This not only makes the formwork cumbersome, leading to difficulties in transportation and increased costs, but also increases the difficulty of construction when lifting the formwork, thus affecting the construction efficiency of steep slopes. The other method is to install tracks to allow the formwork to move within the tracks, but installing the tracks is time-consuming and also reduces the construction efficiency of steep slopes.

[0004] Meanwhile, the existing method of using a winch to lift the formwork is prone to creating an upward angle between the traction wire rope and the slipform due to different connection positions, causing the formwork to float. This requires multiple adjustments to the connection position of the wire rope, resulting in long construction time and low construction efficiency.

[0005] In summary, existing methods for preventing formwork from floating during the construction of steep slopes suffer from low construction efficiency. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a hydraulic slipform device for high and steep slope construction, which addresses the shortcomings of the prior art. The device has a novel and reasonable design, is lightweight and easy to transport, and is simple to install and easy to construct, thus greatly shortening the construction time.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A hydraulic slipform device for construction of steep slopes includes multiple sets of parallel anti-slipform floating components and a slipform body; The anti-slipform floating assembly includes a steel wire rope, a lever hoist for tightening and loosening the steel wire rope, anchor rings for fixing to the upper and lower ends of the slope, and a telescopic support rod perpendicular to the plane of the slipform body. One end of the wire rope is anchored to the anchor ring, and the other end is fixed to another anchor ring by a lever hoist. One end of the telescopic support rod is connected to the wire rope, and the other end is fixedly connected to the sliding mold body. The tightening and loosening of the wire rope are controlled by extending and shortening the rod. The slipform body is connected to a second hydraulic jack via a jack bracket. The second hydraulic jack has a load-bearing rod that is parallel to the sliding direction of the slipform. The lower end of the load-bearing rod is fixed to the poured concrete and is used to lift the slipform body.

[0008] Furthermore, the anti-slippage assembly includes two telescopic support rods.

[0009] Furthermore, the telescopic support rod consists of a movable pin and a first hydraulic jack, and the extension and retraction of the telescopic support rod are controlled by the lifting and retraction of the first hydraulic jack.

[0010] Furthermore, a roller support is installed at the upper end of the slope to support the wire rope and eliminate bending.

[0011] Furthermore, the hydraulic sliding formwork device includes three sets of components to prevent the sliding formwork from floating.

[0012] Furthermore, the anchor ring is fixed by anchor bars.

[0013] Furthermore, the wire rope used is a Φ28 wire rope.

[0014] Furthermore, a vibrating platform is connected to the upper end of the slipform body, a finishing platform is connected to the lower end of the slipform body, and a rainproof canopy is provided above the slipform body. The frame of the rainproof canopy is fixed to the railings of the vibrating platform and the finishing platform. The finishing platform is equipped with rollers underneath.

[0015] Furthermore, the sliding mold body includes a sliding mold main frame and a panel disposed below the sliding mold main frame. This utility model has the following advantages compared with the prior art: This invention utilizes a second hydraulic jack and a support rod to drive the sliding formwork body to slide. Compared to existing methods that use a winch to lift the formwork body, hydraulic driving eliminates the need for multiple adjustments to the connection positions, reducing construction time and improving efficiency. Furthermore, the components of the hydraulically driven formwork body are lighter, facilitating transportation and installation, significantly reducing construction costs. A steel wire rope is installed above the formwork body; tightening the rope applies downward pressure to effectively prevent the formwork from floating. Compared to existing track-based methods, installing the steel wire rope takes less time, significantly improving construction efficiency. Compared to existing methods that add counterweights, the anti-floating component is lighter, facilitating transportation and lifting. The combination of hydraulic drive and the steel wire rope solves the problem of low construction efficiency in existing methods for preventing formwork floating on steep slopes. The anti-floating component uses a lever hoist to significantly adjust the steel wire rope tension; a telescopic support rod allows for fine-tuning of the tension, facilitating the movement of the formwork body; thus achieving precise control of the steel wire rope tension. This improved the flexibility and safety of construction.

[0018] Example of a hydraulic slipform device for construction of steep slopes: like Figures 1-5 As shown, the hydraulic slipform device used for high and steep slope construction includes multiple sets of parallel anti-slipform floating components 1 and slipform body 6.

[0019] The anti-floating component 1 includes a wire rope 11, a lever hoist 12 for tightening and loosening the wire rope 11, anchor rings 13 for fixing to the upper and lower ends of the slope, and a telescopic support rod 15 perpendicular to the plane of the slipform body 6.

[0020] One end of the wire rope 11 is anchored to an anchor ring 13, and the other end is fixed to another anchor ring 13 via a lever hoist 12. One end of the telescopic support rod 15 is connected to the wire rope 11, and the other end is fixedly connected to the slipform body 6. The tightening and loosening of the wire rope 11 is controlled by extending and shortening it. The wire rope 11 is tightened by the two anchor rings 13, causing it to apply a force perpendicular to the pouring surface to the formwork body. The aforementioned wire rope 11 is a Φ28 wire rope.

[0021] The wire rope 11 is supported by the telescopic support rod 15 to prevent the wire rope 11 from bending at a large angle. The two anti-slip mold floating components 1 include two telescopic support rods 15, thereby extending the service life of the wire rope 11.

[0022] To facilitate the extension and retraction of the telescopic support rod 15, it consists of a movable pin 151 and a first hydraulic jack 152. The extension and retraction of the telescopic support rod 15 is controlled by the lifting and retraction of the first hydraulic jack 152. The jack provides a strong lifting force through hydraulic or mechanical principles, and the length of the support rod can be adjusted as needed to adapt to different support height requirements. The movable pin 151 is used to lock the extension and retraction position of the support rod, ensuring its stability during use. The movable pin 151 is made of Φ114×4mm steel pipe, with a 10×10cm steel plate welded to the end. The first hydraulic jack 152 is a 3t jack.

[0023] To prevent the wire rope 11 from directly contacting the surface of the steep slope and causing wear, a roller support 2 is installed at the upper end of the slope to support the wire rope 11 and prevent bending. The roller support 2 also prevents the wire rope 11 from moving.

[0024] In order to ensure that the downward pressure can be applied evenly to the sliding mold body 6, the hydraulic sliding mold device includes three sets of anti-slip mold floating components 1, which effectively prevent the template body from floating.

[0025] The anchor ring 13 is fixed by the anchor bar 14, which is made of Φ25 threaded steel, 1.8m long, and 1.5m deep into the rock.

[0026] The slipform body 6 is connected to a second hydraulic jack 4 via a jack support 3. A support rod 5, parallel to the sliding direction of the slipform, passes through the second hydraulic jack 4. The lower end of the support rod 5 is fixed to the poured concrete and is used to lift the slipform body 6. The jack support 3 is composed of two welded 16# channel steels. The jack support 3 is fixedly installed on the slipform body 6 to support and position the second hydraulic jack 4. The lower end of the support rod 5 is fixed in the poured concrete structure, thus providing stable support and reliable tensile strength for the slipform system. The support rod 5 is made of Φ48.3×3.6mm steel pipe.

[0027] The upper end of the slipform body 6 is connected to a vibratory platform 8. The vibratory platform 8 is made of Φ48.3×3.6mm steel pipe, with a handrail height of 1.2m, and the surface of the vibratory platform 8 is covered with 5cm thick wooden boards.

[0028] The lower end of the sliding mold body 6 is connected to a finishing platform 7, on which a 5cm thick wooden board is also laid.

[0029] A rainproof canopy 9 is installed above the slipform body 6. The frame of the rainproof canopy 9 is fixed to the railings of the vibrating platform 8 and the finishing platform 7. The frame of the rainproof canopy 9 is made of Φ12 round steel welded together, and the canopy fabric is made of 0.3mm thick waterproof cloth.

[0030] Rollers 10 are installed under the finishing platform 7. The rollers 10 can prevent the finishing platform 7 from damaging the poured concrete surface.

[0031] The sliding formwork body 6 includes a sliding formwork main frame 61 and a panel 62 disposed below the sliding formwork main frame 61. The panel 62 is made of 6mm thick steel plate, and the sliding formwork main frame is made of ∠75×5mm equilateral angle steel.

[0032] When using this utility model, the construction should be carried out according to the following steps: S1. Divide the slipform into sections according to its length. Use wooden formwork for the side forms and assemble the formwork body and vibrating platform 8. Next, fix the anchor rings 13 with anchor bars 14. Drill holes using a YT-28 hand drill, with the drilling angle perpendicular downwards and a depth of 1.5m. Clean the holes with high-pressure air before installing the anchor bars 14. The anchor bars 14 are installed by first grouting and then inserting the rods. After the anchor bars 14 are installed and the cement grout strength meets the requirements, weld the anchor rings 13 to the ends of the anchor bars 14. Use a 25t or 50t truck crane to lift the slipform into place.

[0033] S2. Install the anti-floating component 1 for the slipform. After the slipform is in place, install the wire rope 11 and fix its bottom to the anchor ring 13. The wire rope 11 is fixed with rope clips, and there are 4 rope clips. The top of the wire rope 11 is fixed to the lever hoist 12, and it is fixed with 4 rope clips. The end of the lever hoist is fixed to the top anchor ring 13. Adjust the tension of the wire rope 11. To prevent the slipform from floating during construction, tighten the wire rope 11 by lever hoist 12 to make the slipform tightly adhere to the surface of the slipform body 6. Install the support rod 5. The support rod 5 passes through the middle of the hydraulic jack. The hydraulic jack is connected to the jack bracket 3 by bolts.

[0034] S3. Concrete pouring and installation of the finishing platform 7. As the slipform rises, the first hydraulic jack 152 is manually adjusted to ensure the slipform is tightly fitted to the slipform body 6. Simultaneously, the support rods 5 are extended, gradually increasing in length as the slipform body 6 rises. The joints of the support rods 5 are staggered by at least 1.5m, and joints are not allowed to be in the same position. The support rods 5 are extended using bevel welding, and after the joints have cooled naturally, the weld seams are ground smooth using an angle grinder.

[0035] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the present utility model. Any simple modifications, alterations, or equivalent structural changes made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
