Description

Technical Field

[0001] This invention belongs to the field of construction auxiliary equipment technology, specifically a hydraulic guide frame for assisting the construction of HUC steel sheet pile support system. Background Technology

[0002] The composite construction technology of H-shaped and U-shaped sheet piles (HUC) offers high load-bearing capacity, ease of construction, and flexibility, significantly reducing project costs and improving efficiency, and is widely used in engineering construction. This system also boasts advantages such as convenient construction, tight interlocking, high material strength, good waterproofing, and reusability, making it widely applicable in deep foundation pit support projects. The guide frame, a specialized steel support structure ingeniously integrated with a series of custom-designed steel profiles and precision pulleys, plays a crucial role in the construction of the composite sheet piles.

[0003] When using H-beam steel piles, their verticality must be guaranteed. If their verticality is not effectively monitored, the bottom of the piles will not penetrate the bearing layer and will not meet the design requirements. Consequently, the support structure will not be able to withstand sufficient resistance. Therefore, during construction, the verticality of the H-beam steel piles and U-shaped steel sheets must be strictly controlled. Effectively controlling the verticality of HUC steel sheet piles is a core component that not only affects the efficiency of the project progress but also determines the success of HUC-type composite steel sheet pile construction. In traditional construction, the verticality deviation of H-beam steel piles is easily caused by manual adjustments, making it difficult to guarantee the accuracy and straightness of the H-beam steel pile position.

[0004] Therefore, the present invention provides a hydraulic guide frame for assisting in the construction of HUC sheet pile support system. Summary of the Invention

[0019] 1. The present invention discloses a hydraulic guide frame for assisting in the construction of HUC steel sheet pile support systems. The telescopic fixed pulley system of this invention comprises a double-layer limiting structure composed of eight iron pulleys (including two fixed pulleys and six adjustable pulleys), maintaining coaxial straight alignment in both the horizontal and vertical directions. Combined with real-time adjustment of the guide frame's posture using hydraulic jacks, the installation accuracy is controlled within five millimeters. Lubricating oil is evenly applied to the pulley surfaces to ensure that the H-beams do not jam or twist during the sinking process, effectively solving the problem of verticality deviation caused by manual adjustment in traditional construction. The main body of the guide frame is welded from high-strength channel steel and I-beams. The telescopic pulley group and the spacing of the perforated steel plates can be replaced according to the H-beam specifications (H200-H500), adapting to various engineering needs and achieving a device reusability rate of over 90%.

The hydraulic guide frame for assisting the construction of HUC steel sheet pile support system, as described in this invention, allows the sleeve plate to be pulled during use, causing it to pull the spring and move together, thereby stretching the spring. When the sleeve plate moves, it will drive the sponge frame, which will move along with it on the ladder. The sponge frame cleans the ladder, absorbing water stains and preventing people's shoes from slipping on the ladder, thus improving the safety of climbing. It also removes foreign objects adhering to the ladder, improving the cleanliness of the ladder. Attached Figure Description

[0035] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0036] Example 1: As Figure 1-5 and Figure 7 As shown in the embodiment of the present invention, a hydraulic guide frame for assisting the construction of HUC steel sheet pile support system includes multiple reinforcing columns 1, and multiple reinforcing beams 2 are fixedly connected between the upper and lower rows of the reinforcing columns 1.

[0037] In the horizontal direction, multiple diagonal braces 3 are fixedly connected between adjacent pairs of reinforcing columns 1. Horizontal supports 4 are fixedly connected to both sides of the bottom of each reinforcing column 1. A pair of flat beam plates 5 are fixedly connected to the top of each set of horizontal supports 4.

[0038] Hydraulic cylinders 6 are fixedly connected to the sides of the four outermost sets of reinforced columns 1. An angle hydraulic sensing system 7 is fixedly connected to the top of the hydraulic cylinder 6, and a circular base 8 is fixedly connected to the bottom of the hydraulic cylinder 6.

[0039] In the vertical direction, a pair of perforated steel plates 9 are provided between multiple sets of opposite reinforcing beams 2. The top of the perforated steel plates 9 is provided with a telescopic pulley group 10 and a fixed pulley 11. A knob 12 and a telescopic rod 15 are fixedly connected to the telescopic pulley group 10.

[0040] When using H-beam steel piles, their verticality must be ensured. If their verticality is not effectively monitored, the bottom of the steel pile will not penetrate into the bearing layer and will not meet the design requirements. As a result, the support structure will not be able to withstand sufficient resistance. Therefore, during the construction process, the verticality of the H-beam steel piles and U-shaped steel sheets must be strictly controlled. The core component of effectively controlling the verticality of HUC steel sheet piles not only affects the efficiency of the project progress but also determines the success of the HUC type combined steel sheet pile construction. In traditional construction, the verticality deviation of H-beam steel piles is easily caused by manual adjustment, making it difficult to ensure the accuracy and straightness of the position of the H-beam steel piles.

[0041] When using this invention, the guide frame should be kept stable during installation. A jack should be used to assist in adjusting the planar posture of the guide frame to achieve a horizontal and vertical state, and the installation accuracy should be controlled within 3mm. The errors in the planar position and verticality of the guide frame should be adjusted to the specified range.

[0042] The guide frame is installed with a limit adjustment device - pulley system. This system consists of eight iron pulleys, including two cylindrical wide fixed pulleys 11 and six cylindrical wide adjustable telescopic pulley groups 10. It effectively ensures the positioning accuracy and verticality of the H-beam and prevents the steel from twisting during the installation process. The limit adjustment device is divided into upper and lower layers, which are kept on the same straight line in both the plane and vertical directions. The deviation between the axis and the verticality is controlled within five millimeters. Before being put into use, the fixed pulleys 11 and the telescopic pulley groups 10 should be evenly coated with lubricating oil to ensure their normal operation.

[0043] The H-beam is lifted by a truck crane and slowly lowered into the limit adjustment device inside the guide frame. The position of the H-beam is adjusted, and the fixed pulleys 11 and telescopic pulley blocks 10 in the upper and lower layers are tightened to ensure accurate positioning of the H-beam and maintain the stability of the crane. The telescopic pulley blocks 10 are slightly loosened to allow the H-beam to sink and advance by its own weight. The sinking speed should not be too fast to ensure the sinking stability of the H-beam.

[0044] When the H-beam cannot be lowered, a vibratory hammer is used to clamp it and vibrate it to lower it. The lowering speed should not be too fast. Construction can be stopped when the top of the H-beam is 0.6 to 0.8m away from the top surface of the guide frame. After each H-beam main pile is completed, the verticality and axial position of the guide frame should be checked immediately.

[0045] If a large deviation is found, the guide frame should be adjusted in time to ensure its position accuracy and straightness, and to avoid quality problems such as positioning deviation and non-vertical insertion of H-beams;

[0046] During the hoisting of the guide frame, care should be taken to handle it gently to avoid any collision with the sheet piles. Then, a vibratory hammer is used to vibrate and sink the H-shaped main piles and U-shaped auxiliary piles to the design elevation. The top elevation of the HUC combined sheet piles should be kept consistent to ensure that the overall construction effect is neat and uniform.

[0047] like Figure 6 As shown, steel plate walkways 13 are fixedly connected to a pair of sides of the perforated steel plate 9 located on the upper side. Ladders 14 are fixedly connected to the sides of the steel plate walkways 13. The bottom of the ladders 14 is fixedly connected to the top of the horizontal support 4.

[0048] like Figure 6 As shown, the top of the steel plate walkway 13 is fixedly connected to multiple protective columns 16, and multiple protective crossbars 17 are fixedly connected between two adjacent protective columns 16.

[0049] When people walk on the steel plate walkway 13, the protective posts 16 and the protective railings 17 can block them, making it less likely for them to fall off the steel plate walkway 13.

[0050] As shown in 6, the bottom of the steel plate walkway 13 is fixedly connected to a diagonal brace 18, and the side of the diagonal brace 18 away from the steel plate walkway 13 is fixedly connected to the reinforcing beam 2.

[0051] By using diagonal brace 18, the steel plate walkway 13 can be supported, thereby improving its stability.

[0052] Example 2: Figure 8 and Figure 10 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: a plurality of circular grooves 19 are provided on the inner wall of the ladder 14, one end of a spring 20 is fixedly connected to the inner wall of the circular groove 19, and the other end of a pair of springs 20 is fixedly connected to the same socket plate 21. In the initial state, the end of the spring 20 connected to the socket plate 21 is flush with the circular groove 19. An installation groove 22 is provided on the side of the socket plate 21, and a reinforcing frame 23 is movably inserted into the installation groove 22. A sponge frame 24 is fixedly connected to the inner wall of the reinforcing frame 23.

[0053] In use, the socket plate 21 can be pulled to move the spring 20 together, thereby stretching the spring 20. When the socket plate 21 moves, it will drive the sponge frame 24 to move together on the ladder 14. The sponge frame 24 is used to clean the ladder 14, which not only absorbs water stains on the ladder 14, making it less likely for people's shoes to slip on the ladder 14 and improving the safety of people climbing the ladder 14, but also removes foreign objects adhering to the ladder 14, improving the cleanliness of the ladder 14.

[0054] like Figure 7 As shown, the top of the reinforcing frame 23 is fixedly connected to the plug-in frame 25, and the inner top wall of the mounting groove 22 is provided with a limiting groove 26 that is movably inserted into the plug-in frame 25.

[0055] After the reinforcing bracket 23 is inserted into the mounting slot 22, the plug-in bracket 25 will enter the limiting slot 26. The plug-in bracket 25 can improve the stability of the reinforcing bracket 23 in the mounting slot 22.

[0056] like Figure 10 As shown, the side of the socket plate 21 away from the spring 20 is magnetically connected to a metal sealing frame 28 through a magnetic coating 27. The side of the metal sealing frame 28 near the socket plate 21 is fixedly connected to a reinforcing rod 29. The side of the socket plate 21 is provided with a mating groove 30 that is movably inserted into the reinforcing rod 29.

[0057] In use, the metal sealing frame 28 is placed against one side of the socket plate 21 to seal the sponge frame 24 inside the socket plate 21, thereby reducing the amount of dust and foreign matter adhering to the sponge frame 24. At the same time, the magnetic coating 27 will be magnetically connected to the metal sealing frame 28, thereby improving the stability of the metal sealing frame 28 on the socket plate 21.

[0058] like Figure 10 As shown, a limiting frame 31 is fixedly connected to the inner wall of the ladder 14. A collecting plate 32 is sleeved on the bottom of the limiting frame 31. A collecting groove 34 and a connecting groove 33 that is movably inserted into the limiting frame 31 are provided on the collecting plate 32. A pair of through grooves 38 that are movably inserted into the limiting frame 31 are provided on the bottom of the connecting plate 21.

[0059] Before wiping and cleaning the surface of the ladder 14 using the sponge frame 24 and moving the connecting plate 21, the collecting plate 32 needs to be moved away from the other side until the collecting plate 32 is removed from under the ladder 14 (in conjunction with...). Figure 12As shown), when the ladder 14 is wiped and cleaned using the sponge rack 24, the foreign objects pushed away by the sponge rack 24 will fall from the ladder 14 into the collection groove 34 on the collection plate 32, which makes it easier for personnel to collect and temporarily store the removed foreign objects, preventing the ground from becoming dirty and messy due to foreign objects falling on the ground.

[0060] like Figure 11-12 As shown, a metal scraper 36 is magnetically connected inside the collection tank 34 through a magnetic coating 35, and multiple rubber strips 37 are fixedly connected to the ladder 14.

[0061] After cleaning the ladder 14, move the metal scraper 36 to push the foreign objects adhering to the collection tank 34, causing the foreign objects to accumulate together. Push the foreign objects to the edge of the collection tank 34, and after the side of the metal scraper 36 abuts against the inner wall of the collection tank 34, move the metal scraper 36 upward to remove the foreign objects accumulated on it from the collection tank 34, thus making it easier for personnel to clean the collection tank 34.

[0062] When personnel climb ladder 14, the rubber strip 37 can reduce the injury to the personnel's legs and knees caused by the collision with ladder 14. At the same time, the rubber strip 37 can also increase the friction between the personnel's shoe soles and ladder 14, making it less likely for the personnel's shoe soles to slip on ladder 14, thereby improving the stability of personnel when climbing ladder 14.
