Technical Field
[0001] This utility model relates to the field of protective plate equipment technology, specifically a soil and rock retaining plate structure. Background Technology
[0002] Earthwork retaining wall structure is a structural system used in earthwork engineering to support, retain soil, and protect construction areas such as excavated foundation pits and slopes. It is usually made of steel plates, structural steel, and other materials to form a retaining wall, which is connected in a reasonable way to form an integral structure to resist the lateral pressure of the soil, prevent collapse, ensure the stability of the soil around the construction area, and provide a safe working environment for earthwork excavation and underground structure construction. It is widely used in building foundation pits, municipal engineering and other fields.
[0003] Existing Chinese patent document CN219137745U discloses an earthwork retaining panel, including a retaining panel and two telescopic anchoring mechanisms. The two telescopic anchoring mechanisms are installed at both ends of the front surface of the retaining panel. Multiple hangers and flip plates are respectively installed at both ends of the retaining panel. The hangers have slots for inserting the flip plates. A suspension opening is provided in the middle of the retaining panel, and support plates are fixedly installed at both ends of the lower part of the retaining panel. This patent has a simple structure, is easy to operate, and can improve the efficiency of earthwork retaining. The retaining panel can be stably supported by the telescopic anchoring mechanisms. On the ground, it serves as a barrier for earthwork. When multiple guard panels need to be connected, the flip plates of adjacent guard panels can be inserted into the slots of the hanger. Support plates are fixedly installed at both ends of the lower part of the guard panel, which can increase the stability of the guard panel on the ground when it is lowered from the lifting equipment. However, the earthwork retaining panel structure still has shortcomings: in terms of splicing method, the slot connection between the hanger and the flip plate can only achieve a fixed splicing at a single angle, which is difficult to meet the protection needs under complex terrain, such as arc-shaped and multi-angle turning areas, thus limiting the shape flexibility of the retaining structure.

In the description of this utility model, it should be noted that unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The embodiments of this utility model will be described below based on its overall structure.
[0016] Reference Figures 1 to 7 In this embodiment of the utility model, an earthwork retaining wall structure includes: a retaining wall 1, a sleeve column 2 fixedly connected to the middle section of one side of the retaining wall 1, and a plug block 3 symmetrically fixedly connected to the top and bottom of the other side of the retaining wall 1. The sleeve column 2 has a through-rod groove 4, and two sets of straight plugs 5 are inserted through the through-rod groove 4. A tension spring 7 is connected between the two sets of straight plugs 5. A positioning disc 8 is fixedly connected to one end face of the straight plug 5. Several sets of positioning columns 9 are evenly fixedly connected in a ring on the top surface of the positioning disc 8. A positioning groove 10 is opened inside the plug block 3. Several sets of positioning grooves 11 are evenly opened in a ring on the bottom surface of the positioning groove 10.
[0017] Reference Figures 1 to 7 A tightening side groove 12 is provided through the middle section of the inner side of the rod groove 4. Rod side blocks 6 are fixed to the same side of the opposite ends of the two sets of straight rods 5. The rod side blocks 6 pass through the tightening side groove 12. The distance between the two sets of straight rods 5 is controlled by squeezing or loosening the two sets of rod side blocks 6 in conjunction with the tension spring 7.
[0018] The above scheme is adopted: the tightening side groove 12 is opened laterally along the middle section of the inner side of the through-rod groove 4, and its width is slightly larger than the width of the rod side block 6, ensuring that the rod side block 6 can slide smoothly in the groove. The rod side block 6 and the straight insertion rod 5 are fixed by welding. The surface can be treated with anti-slip treatment, such as setting texture or rubber pads, to facilitate the operation of construction personnel. In actual operation, the construction personnel squeeze the two sets of rod side blocks 6 to overcome the elastic force of the tension spring 7, so that the two sets of straight insertion rods 5 are brought closer to each other, thereby reducing the gap. When the rod side blocks 6 are released, the tension spring 7 returns to its original position and pushes the straight insertion rod 5 to extend outward. The functional advantage of this structure is that it provides a convenient operation method for splicing and disassembling the enclosure panel, facilitates reuse, reduces construction costs, and also improves the flexibility and efficiency of construction.
[0019] Reference Figures 1 to 7 The positioning disc 8 and the positioning groove 10 are matched in specifications. The positioning pins 9 and the positioning grooves 11 are matched in quantity, specifications and position. The straight insertion rod 5 is tensioned by a spring 7 structure so that the positioning disc 8 at its end face is always pressed against the corresponding positioning groove 10. Several sets of positioning pins 9 and positioning grooves 11 are selected at appropriate angles to accurately engage, so as to fix the included angle of two adjacent sets of guard plates 1.
[0020] The above scheme employs a dimensionally precise matching between the positioning disc 8 and the positioning groove 10. The diameter of the positioning disc 8 is slightly smaller than the inner diameter of the positioning groove 10, ensuring both smooth insertion of the positioning disc 8 into the positioning groove 10 and a tight fit. The number of positioning posts 9 and positioning grooves 11 is set to twelve sets according to actual needs, evenly distributed along the edges of the positioning disc 8 and the positioning groove 10. In terms of specifications, the diameter and length of the positioning posts 9 match the width and depth of the positioning grooves 11, ensuring precise engagement. When the straight insertion rod 5 is in tension... When the positioning disc 8 is pushed into the positioning groove 10 by the spring 7, the positioning post 9 will automatically embed into the corresponding positioning groove 11. The advantage of this structure is that it not only achieves a firm connection between adjacent protective plates, but also allows for flexible adjustment of the included angle between adjacent protective plates according to the terrain and requirements of the construction site. Whether it is a right angle, acute angle or obtuse angle connection, it can be achieved by the different angles of the positioning post 9 and the positioning groove 11, which greatly enhances the adaptability of the earthwork retaining plate structure, can better fit the complex construction environment, and improve the retaining effect.
[0021] Reference Figures 1 to 7 A support plate 13 is hinged to one side of the bottom end of the guard plate 1. A ground nail 14 is inserted through one end of the support plate 13. Two sets of ground nails 14 are symmetrically inserted through each set of support plates 13. There are two sets of support plates 13, and each set is connected with the same number and specifications of ground nail 14 structures.
[0022] The above scheme is adopted: the support plate 13 is hinged to one side of the bottom end of the guard plate 1. The ground nail 14 is generally a long strip of metal nail with a cap at the top for easy hammering and a sharp bottom for easy insertion into the ground. Two ground nails 14 are symmetrically arranged for each set of support plates 13. By hammering the ground nails 14, the support plate 13 is fixed to the ground. The functional advantage of this structure is that it provides stable ground support for the guard plate. The angle of the support plate 13 can be adjusted according to the actual ground conditions to better fit the ground and enhance stability. It is not only suitable for flat ground, but also for sloping ground, improving the applicability of the equipment. The ground nails 14 firmly fix the support plate 13 to the ground, preventing the guard plate from shifting or tilting under the pressure of earth and rock, effectively ensuring safety during construction, and also improving the adaptability of the guard plate structure to different ground conditions.
[0023] Reference Figures 1 to 7 Two sets of support plates 13 are hinged to one end of a sleeve 15 on their top surfaces. The top of the guard plate 1 on the same side as the support plate 13 is hinged to a through rod 16. The through rod 16 and the sleeve 15 are telescopically connected to each other. Several sets of slots 17 are evenly opened on one side of the through rod 16. A block groove 18 is opened through one side of the sleeve 15. An arc-shaped part 19 is fixed to the outside of the sleeve 15 at the block groove 18. A locking block 20 is inserted inside the block groove 18. A tension spring 21 is fixed to one end of the locking block 20 and the other end of the tension spring 21 is fixed to the inside of the arc-shaped part 19. L-shaped buckles 22 are symmetrically hinged to the same end on both sides of the locking block 20. Magnetic plates 23 are embedded on the outside of the arc-shaped part 19 at the corresponding position of the L-shaped buckle 22.
[0024] The above scheme is adopted: the sleeve 15 and the through rod 16 are respectively hinged to the top of the support plate 13 and the guard plate 1 via hinge shafts, allowing them to rotate freely within a certain range to adapt to different connection angle requirements. In actual use, when it is necessary to adjust the tilt angle or stability of the guard plate 1, the construction personnel can pry open the two sets of L-shaped buckle plates 22 so that they are tightly fastened to the inside of the bow-shaped part 19 with the magnetic suction piece 23, releasing the abutment of the locking block 20 against the locking groove 17, so that the through rod 16 and the sleeve 15 can be flexibly adjusted to adjust the degree of extension and retraction. When the extension and retraction state is confirmed, the L-shaped buckle plates 22 can be opened, so that the locking block 20 automatically enters the block groove 18 and abuts into the locking groove 17 under the reset action of the tension spring 21, so as to fix the extension and retraction state of the through rod 16 and the sleeve 15. The functional advantage of this structure is that it provides a flexible and reliable angle adjustment and reinforcement method for the retaining plate, and can adjust the angle of the guard plate 1 in real time according to the pressure distribution of the earthwork and construction requirements, so that it can better withstand the pressure and enhance the overall stability of the retaining structure.
[0025] The working principle of this utility model is as follows: During installation, the construction personnel squeeze the rod side block 6 to overcome the elastic force of the tension spring 7, thereby reducing the distance between the two sets of straight insertion rods 5. Then, the straight insertion rod 5 on the sleeve rod post 2 is inserted into the insertion rod block 3 of the adjacent guard plate. After releasing the rod side block 6, the tension spring 7 returns to its original position, pushing the straight insertion rod 5 to extend outward, so that the positioning disc 8 presses against the positioning groove 10. At the same time, the positioning post 9 is embedded into the positioning groove 11, completing the splicing and fixing of the adjacent guard plates. The angle between each set of guard plates 1 can be flexibly changed by adjusting the engagement angle between the positioning post 9 and the positioning groove 11 to adapt to different enclosure shapes and specifications. In terms of fixed support, the support plate 13 is hinged to one side of the bottom end of the guard plate 1. The ground nail 14 is generally a long strip of metal nail with a cap at the top for easy hammering and a sharp bottom for easy insertion into the ground. Two ground nails 14 are symmetrically arranged in each set of support plates 13. By hammering the ground nails 14, the support plate 13 is fixed to the ground. The functional advantage of this structure is that it provides stable ground support for the guard plate. The angle of the support plate 13 can be adjusted according to the actual ground conditions to better fit the ground and enhance stability. It is not only suitable for flat ground, but also for sloping ground, improving the applicability of the equipment. When it is necessary to adjust the tilt angle or stability of the protective plate 1, the construction personnel can pry open the two sets of L-shaped buckles 22 so that they are fastened to the inside of the bow-shaped part 19 with the magnetic suction piece 23, thereby releasing the abutment of the locking block 20 against the slot 17. This allows the extension and retraction of the through rod 16 and the sleeve 15 to be flexibly adjusted. When the extension and retraction state is confirmed, the L-shaped buckles 22 can be pried open so that the locking block 20 automatically passes into the block groove 18 and abuts into the slot 17 under the reset action of the tension spring 21, thus fixing the extension and retraction state of the through rod 16 and the sleeve 15. The functional advantage of this structure is that it provides a flexible and reliable angle adjustment and reinforcement method for the protective plate. It can adjust the angle of the protective plate 1 in real time according to the pressure distribution of the earthwork and construction needs, so that it can better withstand the pressure and enhance the overall stability of the protective structure.
[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
