Description

Technical Field

[0001] This application relates to the field of roadbed slope protection construction technology, and in particular to a slope control device for slope protection. Background Technology

[0002] Slope protection is a measure used in engineering projects such as highways and railways to protect slopes. It is usually installed at the toe of the slope of an embankment, located between the toe and the ditch. Its main functions include stabilizing the slope, reducing erosion, and guiding drainage. By increasing the bearing area of ​​the roadbed, slope protection effectively disperses soil pressure, preventing slope slippage or collapse, while also reducing the direct erosion of the slope by rainwater or surface runoff, thus avoiding slope erosion.

[0003] However, in actual construction, controlling the slope gradient is one of the key factors in ensuring project quality and long-term stability. Traditional slope protection construction methods mainly rely on manual layout, formwork support, or simple support structures to adjust the slope. While these methods meet construction requirements to some extent, they have some significant shortcomings. For example, manual layout and simple support structures are difficult to control the slope, and construction errors may lead to substandard slopes, affecting project quality. Traditional methods also lack flexibility during construction; if the design is changed, the original structure often needs to be dismantled, increasing construction time and costs. Furthermore, the installation and dismantling of formwork support structures are cumbersome, especially when working on high slopes or above retaining walls, causing inconvenience and severely impacting construction progress.

[0004] Currently, although some adjustable slope protection support devices have been proposed, such as those using screws and support frames for adjustment, these devices still have certain limitations in terms of adjustment range, ease of installation, and stability. Therefore, there is an urgent need for a new slope protection control device that is simple in structure, flexible in adjustment, and easy to install, capable of controlling the slope gradient, thereby improving construction efficiency, reducing project costs, and adapting to various construction environments. Utility Model Content

[0005] In order to improve the ease of installation and adjustment while controlling the slope of the slope, and to ensure the stability and reliability of the device structure, this application provides a slope control device.

[0006] The slope control device provided in this application adopts the following technical solution:

[0007] A slope control device for slope protection, comprising:

[0008] Angle steel is used for installation on existing retaining walls at the toe of slopes.

[0009] A telescopic adjusting rod is installed on the angle steel. The adjusting rod can rotate in the vertical plane to control the slope of the slope protection. The angle between the adjusting rod and the horizontal direction is equal to the slope angle of the slope protection.

[0010] The slope protection formwork is fixed to the slope surface and used in conjunction with the adjusting rod to limit the range of concrete pouring for slope protection.

[0011] By adopting the above technical solution, this device uses angle steel to be directly installed on the existing retaining wall, making full use of the retaining wall's structure without the need for additional support structures. The adjustment mechanism of the adjusting rod allows construction workers to easily adjust the slope. The design of this device simplifies the slope control and formwork installation process in slope protection construction, simplifies the construction process, improves construction efficiency, reduces reliance on additional support materials, and reduces construction complexity, thereby improving work efficiency. Through the adjustable design of the adjusting rod and the rigid support between the adjusting rod and the slope protection formwork, the slope of the slope can be accurately controlled. The angle between the adjusting rod and the horizontal direction can be adjusted according to design requirements to ensure accurate slope control. The device has a simple structure and is reusable, which not only reduces the waste of construction materials but also greatly reduces construction costs. It is easy to install and disassemble and can be reused in multiple projects, further optimizing cost-effectiveness.

[0012] In one specific implementation, the angle steel and the adjusting rod are connected by an adjusting screw, the adjusting screw passes through the angle steel and then through the adjusting rod, and an adjusting nut is threadedly connected to one end of the adjusting screw that protrudes from the adjusting rod.

[0013] By adopting the above technical solution, the design of the adjusting screw and adjusting nut makes the angle adjustment of the adjusting rod simple and quick. After loosening the adjusting nut, the adjusting rod can be freely rotated to adjust its position, and then the adjusting nut can be tightened to fix it, so as to quickly and conveniently complete the slope adjustment.

[0014] In one specific implementation, the angle steel is provided with an adjustment groove arranged along its length. The adjustment groove is used to adjust the installation position of the adjustment rod. The adjustment screw passes through the adjustment groove and then through the adjustment rod for fixation.

[0015] By adopting the above technical solution, the adjustment groove set on the angle steel allows the installation position of the adjustment rod to be adjusted along the length direction. The setting of the adjustment screw helps to control the forward and backward movement of the adjustment rod, thereby meeting the slope adjustment needs of slopes with different widths. Moreover, the position of the adjustment rod can be quickly adjusted by simply rotating the adjustment nut and the adjustment screw, without disassembly or reassembly, and the adjustment can be completed directly by adjusting the screw. This design allows the slope of the slope to be adjusted according to different design widths. Whether it is a narrow or wide slope, the corresponding slope adjustment can be quickly achieved by moving the adjustment rod forward and backward.

[0016] In one specific implementation, the adjusting rod is connected to the angle steel via a hinged structure.

[0017] By adopting the above technical solution, construction workers can manually or through other means adjust the relative angle between the adjusting rod and the angle steel, thereby changing the angle of the adjusting rod to adjust the slope of the slope. Through the simple hinge design, flexible connection and adjustment between the adjusting rod and the angle steel can be achieved, making operation and adjustment more direct and simple, avoiding additional adjustment steps and complex adjustment tools, and allowing users to complete the adjustment more quickly.

[0018] In one specific implementation, an angle scale mark is also included, which is located on the side of the angle steel near the adjusting rod, for indicating the rotation angle of the adjusting rod.

[0019] By adopting the above technical solution and adding angle scale markings, construction workers can see the angle between the adjusting rod and the horizontal direction in real time when adjusting the adjusting rod. They can directly adjust to the slope required by the design according to the scale, reducing uncertainty and misoperation in the adjustment process, thereby improving the accuracy of slope adjustment, simplifying the construction process, and improving work efficiency.

[0020] In one specific implementation, the angle steel is arranged along the width direction of the existing retaining wall and is detachably fixed to the existing retaining wall by fixing nails.

[0021] By adopting the above technical solution, the angle steel can be detachably fixed to the existing retaining wall with fixing nails. The installation process is simple. Construction workers only need to place the angle steel in the appropriate position and then fix it with fixing nails. Moreover, after the construction is completed, the angle steel can be easily disassembled, avoiding the difficulty of dismantling later due to overly fixed installation, thereby saving dismantling costs and time.

[0022] In one specific implementation scheme, the angle steel is provided with an installation groove along the height direction for adjusting the installation height of the angle steel, and the fixing nail passes through the installation groove before connecting to the existing retaining wall.

[0023] By adopting the above technical solution and utilizing the design of the installation groove, the installation height of the angle steel can be flexibly adjusted as needed, enhancing the flexibility of installation and enabling the angle steel to be installed at different heights to meet the needs of slope protection projects with different height requirements, thereby improving the stability and adaptability of the entire device.

[0024] In one specific implementation scheme, the angle steel and the adjusting rod are set in multiple groups and are evenly distributed along the length of the existing retaining wall.

[0025] By adopting the above technical solution, and utilizing multiple sets of evenly arranged angle steel and adjusting rods, the overall shape and position of the formwork can be effectively controlled, ensuring that the slope surface after pouring remains on the same plane, avoiding uneven slopes, and thus improving construction quality. Furthermore, the multiple sets of angle steel and adjusting rods can provide uniform force distribution at different support points, avoiding the problem of excessive or insufficient local support force, making the formwork less prone to deformation during pouring, and ensuring the accurate shape and slope of the slope after pouring.

[0026] In one specific implementation scheme, the slope protection formwork is arranged along the length of the existing retaining wall, and the end of the adjusting rod away from the angle steel abuts against the slope protection formwork and is detachably connected to the slope protection formwork.

[0027] By adopting the above technical solution, the adjusting rod is fixed to the slope protection formwork. The slope protection formwork supports the adjusting rod to prevent it from shifting or deforming due to external forces during concrete pouring, thus ensuring that the adjusting rod remains stable during the pouring process and ensuring that the shape and slope of the slope protection do not shift during the pouring process.

[0028] In one specific implementation, the contact surface between the angle steel and the existing retaining wall is provided with anti-slip pads.

[0029] By adopting the above technical solutions, the friction between the angle steel and the existing retaining wall can be improved, avoiding slippage or relative movement during the stress process. This allows the angle steel to be better fixed to the concrete wall during construction, preventing displacement or misalignment due to insufficient friction, and further improving the accuracy of the shape and slope of the slope after pouring.

[0030] In summary, the beneficial technical effects of this application are as follows: This device fully utilizes the retaining wall structure by directly installing angle steel on the existing retaining wall, avoiding the need for additional support structures; through the adjustable design of the adjusting rod and the rigid support between the adjusting rod and the slope protection formwork, the slope of the slope protection can be accurately controlled, and the angle between the adjusting rod and the horizontal direction can be adjusted according to design requirements to ensure accurate slope control, improve construction precision, and avoid errors that may occur in traditional methods;

[0031] This device is particularly suitable for slope protection projects on the top of retaining walls, and can adapt to different slope requirements and complex terrain applications. In addition, the device has a simple structure and is reusable, which not only reduces construction costs, but can also be used in multiple projects to optimize cost-effectiveness and improve work efficiency, and has good application prospects.

[0037] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0038] Example 1

[0039] Reference Figure 1-3 This application discloses a slope control device for roadbed edging projects. The slope control device includes:

[0040] Multiple angle steels 2 serve as a support structure and are used to install on the existing retaining wall 1 at the toe of the slope. In this embodiment, the angle steels 2 are arranged along the width direction of the existing retaining wall 1, and the multiple angle steels 2 are evenly distributed along the length direction of the existing retaining wall 1.

[0041] Multiple adjusting rods 3 are set one-to-one with angle steel 2. The adjusting rods 3 are respectively installed on the angle steel 2. The adjusting rods 3 can rotate in the vertical plane to control the slope of the slope. The angle between the adjusting rod 3 and the horizontal direction is equal to the slope angle of the slope.

[0042] The adjusting rod 3 is designed to be telescopic, and its length can be adjusted as needed. In this embodiment, the adjusting rod 3 includes, but is not limited to, a two-section sleeve rod structure, which consists of two sleeved rods. The inner and outer rods are connected to each other by sleeve. The inner rod can slide inside the outer rod. The length can be adjusted by rotation or stretching to achieve telescopic adjustment. During the adjustment process, the inner and outer rods are fixed by a buckle, threaded connection or locking device to prevent the adjusting rod 3 from loosening during use.

[0043] The slope protection template 4 is fixed on the slope surface. In this embodiment, the slope protection template 4 is set along the length of the existing retaining wall 1. The end of the adjusting rod 3 away from the angle steel 2 abuts against the slope protection template 4 and is detachably connected to the slope protection template 4. In this embodiment, the adjusting rod 3 and the slope protection template 4 are detachably connected by bolts, but not limited to bolts. Specifically, a connecting groove set along the height direction can be set on the slope protection template 4, and then bolts can be passed through the connecting groove to connect with the adjusting rod 3, so as to facilitate the adjustment rod 3 to meet the construction requirements of slope protection with different slopes.

[0044] The slope protection formwork 4 is used in conjunction with the adjusting rod 3 to limit the range of concrete pouring for the slope protection. In this embodiment, the range of concrete pouring for the slope protection is the space formed between the slope surface, the existing retaining wall 1, the slope protection formwork 4 and the adjusting rod 3.

[0045] During construction, firstly, multiple angle steels 2 are evenly distributed along the length of the existing retaining wall 1 and fixed one by one to the existing retaining wall 1. The slope protection formwork 4 is then fixed to the slope surface. Next, the slope is adjusted according to the design requirements by rotating the adjusting rod 3 installed on the angle steel 2 so that its angle with the horizontal direction is equal to the slope angle of the slope, thereby controlling the slope. After the angle is adjusted, the adjusting rod 3 is fixed to the slope protection formwork 4. The slope protection formwork 4 and the adjusting rod 3 work together to limit the range of concrete pouring for the slope protection. After the adjustment is completed, the concrete is poured. Under the restriction of the slope protection formwork 4 and the adjusting rod 3, the concrete is poured and shaped according to the design requirements to ensure the structural strength and stability of the slope. After the concrete is poured and the slope protection concrete has finally set, the slope protection formwork 4 and the angle steel 2 are removed. At this point, the slope protection has been stabilized.

[0046] In this embodiment, the slope control device also includes an angle scale mark 8. Each angle steel 2 is equipped with an angle scale mark 8. The angle scale mark 8 is located on the side of the angle steel 2 near the adjusting rod 3. In this embodiment, the angle scale mark 8 is located at the connection between the adjusting rod 3 and the angle steel 2, and is used to indicate the rotation angle of the adjusting rod 3. The angle scale mark 8 can be fixedly set or detachably set on the angle steel 2.

[0047] When adjusting the adjusting rod 3, the construction personnel can see the angle between the adjusting rod 3 and the horizontal direction in real time through the angle scale mark 8, and directly adjust it to the slope required by the design according to the scale mark 8, thereby reducing the uncertainty and misoperation in the adjustment process and improving the accuracy of slope adjustment.

[0048] In this embodiment, the angle steel 2 and the adjusting rod 3 are connected by an adjusting screw 5. The angle steel 2 is provided with an adjusting groove 21 along its length. The adjusting groove 21 is used to adjust the installation position of the adjusting rod 3. The adjusting screw 5 passes through the adjusting groove 21 and then through the adjusting rod 3 for fixing. One end of the adjusting screw 5 that passes through the adjusting rod 3 is threadedly connected to an adjusting nut 6. In this embodiment, the adjusting nut 6 is a wing nut or a nut with a handle, which is convenient for manual adjustment.

[0049] During construction, according to different design width and slope requirements, the position of the adjusting screw 5 can be adjusted to allow the adjusting rod 3 to move back and forth within the adjusting groove 21. By loosening the adjusting nut 6, the adjusting screw 5 can be moved, changing its installation position relative to the angle steel 2, thereby adjusting the installation position of the adjusting rod 3. After moving to the target position, the adjusting rod 3 is rotated, causing it to rotate on the adjusting screw 5, thus changing the angle of the adjusting rod 3. After adjusting to the required position, the adjusting nut 6 is tightened, pressing the adjusting rod 3 against the angle steel 2, thus fixing the adjusting rod 3. In this embodiment, the order of moving and rotating adjustment during the adjustment of the adjusting rod 3 can be changed, and can be adjusted according to actual conditions.

[0050] During this process, the adjustment groove 21 set on the angle steel 2 allows the installation position of the adjustment rod 3 to be adjusted along the length direction. The setting of the adjustment screw 5 helps to control the back-and-forth movement of the adjustment rod 3, thereby meeting the slope adjustment requirements of slopes with different widths. Through the design of the adjustment screw 5, the adjustment nut 6 and the adjustment groove 21, construction workers can quickly adjust the position of the adjustment rod 3 by simply rotating the adjustment nut 6 and the adjustment screw 5, without disassembly or reassembly, and the adjustment can be completed directly by adjusting the screw 5. This design scheme allows the slope of the slope to be adjusted according to different design widths. Whether it is a narrow slope or a wide slope, the corresponding slope adjustment can be quickly achieved by moving the adjustment rod 3 back and forth.

[0051] In this embodiment, the angle steel 2 is provided with an installation groove 22 arranged along the height direction for adjusting the installation height of the angle steel 2. The angle steel 2 is arranged along the width direction of the existing retaining wall 1. The angle steel 2 is detachably fixed to the existing retaining wall 1 by fixing nails 9. In this embodiment, the fixing nails 9 can be, but are not limited to, pins or screws. The fixing nails 9 first pass through the installation groove 22 and then connect to the existing retaining wall 1. The fixing nails 9 press and fix the angle steel 2 against the existing retaining wall 1.

[0052] With the design of the mounting slot 22, the installation height of the angle steel 2 can be flexibly adjusted as needed, enhancing the flexibility of installation and enabling the angle steel 2 to be installed at different heights to meet the needs of slope protection projects with different height requirements, thereby improving the stability and adaptability of the entire device.

[0053] The contact surface between the angle steel 2 and the existing retaining wall 1 is provided with anti-slip pads. In this embodiment, the anti-slip pads include, but are not limited to, rubber anti-slip pads, and the surface is pressed with wavy anti-slip patterns. The design of the anti-slip pads can improve the friction between the angle steel 2 and the existing retaining wall 1, avoid slippage or relative movement during the stress process, so that the angle steel 2 can be better fixed to the concrete wall during construction, prevent displacement or misalignment due to insufficient friction, and further improve the accuracy of the shape and slope of the slope after pouring.

[0054] The implementation principle of this application embodiment is as follows: During construction, multiple angle steels 2 are evenly distributed along the length of the existing retaining wall 1, and the angle steels 2 are fixed to the retaining wall by fixing nails 9. The fixing nails 9 pass through the installation grooves 22 on the angle steels 2 and are connected to the existing retaining wall 1. During this process, the installation height of the angle steels 2 can be adjusted according to the actual construction requirements. By loosening the fixing nails 9, the installation grooves 22 can slide up and down along the fixing nails 9 to adjust the installation height of the angle steels 2. After adjustment, the fixing nails 9 are tightened so that the fixing nails 9 press the angle steels 2 against the existing retaining wall 1 to ensure the stability of the angle steels 2.

[0055] Fix the slope protection formwork 4 to the slope surface. Then, according to the slope protection gradient required by the design, start adjusting the angle of the adjusting rod 3 on each angle steel 2. According to the design width and slope requirements, the construction personnel first loosen the adjusting nut 6 and move the adjusting screw 5 to change the installation position of the adjusting screw 5 relative to the angle steel 2, thereby adjusting the installation position of the adjusting rod 3. After moving to the target position, rotate the adjusting rod 3. The adjusting rod 3 rotates on the adjusting screw 5, thereby changing the angle of the adjusting rod 3. During this process, the angle between the adjusting rod 3 and the horizontal direction can be seen through the angle scale mark 8. Adjust to the slope required by the design according to the scale on the angle scale mark 8. After adjusting to the required position, tighten the adjusting nut 6. The adjusting nut 6 presses the adjusting rod 3 against the angle steel 2, completing the fixing of the adjusting rod 3. At this time, the end of the adjusting rod 3 away from the angle steel 2 needs to be fixed to the slope protection formwork 4, together with the slope protection formwork 4, to limit the range of slope protection concrete pouring.

[0056] After adjustment, the concrete pouring operation begins. Under the constraints of the slope protection formwork 4, adjustment rod 3, and existing retaining wall 1, the concrete is poured according to the design requirements to ensure that the concrete molding conforms to the designed slope and shape. After the slope protection concrete is poured and reaches final setting, the slope protection formwork 4 and angle steel 2 are removed. At this point, the slope of the slope protection has been stabilized, and the shape and stability of the entire slope protection structure are established.

[0057] The slope control device of this application achieves simple and accurate slope control by fixing the angle steel 2 to the existing retaining wall 1 and combining it with the adjustable adjusting rod 3 and the slope protection formwork 4. The design of this device can simplify the slope adjustment and formwork installation process in slope protection construction, reduce the reliance on additional support materials during construction, and improve construction efficiency and accuracy. Through the design of the adjusting screw 5 and the adjusting groove 21, the construction personnel can flexibly adjust the angle and position of the adjusting rod 3 to ensure that the slope protection meets the design requirements. Moreover, the device can be reused, reducing construction costs.

[0058] In addition, the use of multiple sets of evenly arranged angle steel 2 and adjusting rods 3 ensures the stability of the formwork during the pouring process, preventing displacement or deformation caused by external forces and ensuring the consistency of the shape and slope of the slope protection structure. Anti-slip pads are installed on the contact surface between the angle steel 2 and the retaining wall to enhance the fixing effect and further improve the accuracy of construction. This device is particularly suitable for slope protection projects on the top of retaining walls and can adapt to different slope requirements. Whether for designs targeting different slope angles or applications in complex terrain, the adjustability of the adjusting rods 3 and the cooperation of the slope protection formwork 4 can meet various construction needs and have strong adaptability and stability.

[0059] Example 2

[0060] Reference Figure 4 The difference between this embodiment and the first embodiment is that the adjusting rod 3 is hinged and fixed to the angle steel 2. One end of the adjusting rod 3 is connected to the angle steel 2 through the hinge structure 7. The hinge connection design allows the adjusting rod 3 to rotate or swing around the hinge structure 7. In this embodiment, the hinge structure 7 can be locked by its own structure or fixed by other fixing devices, including but not limited to fixing with pins.

[0061] During adjustment, construction workers can manually or otherwise rotate the adjusting rod 3. The adjusting rod 3 can rotate or swing around the hinge structure 7 to adjust the relative angle between the adjusting rod 3 and the horizontal direction, thereby changing the angle of the adjusting rod 3 to adjust the slope of the slope. After adjustment, the end of the adjusting rod 3 away from the angle steel 2 needs to be fixed to the slope protection formwork 4. The adjusting rod 3 and the slope protection formwork 4 together limit the range of concrete pouring for the slope protection, ensuring that the shape and slope of the slope protection meet the design requirements. During this process, the slope protection formwork 4 can also assist in supporting the adjusting rod 3 to ensure the positional stability of the adjusting rod 3.

[0062] This embodiment provides a flexible and convenient connection between the adjusting rod 3 and the angle steel 2 through a simple hinge design. The operation is more intuitive and quick, and construction personnel can quickly complete the adjustment of the slope without the need for additional complicated adjustment tools. The hinge design can avoid unnecessary adjustment steps and further improve construction efficiency.

[0063] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
