Description

Technical Field

[0001] This application relates to the field of civil engineering technology, and in particular to a zoned shotcrete and anchor support structure for ultra-large foundation pits. Background Technology

[0002] The ultra-large foundation pit zoned shotcrete and anchor support structure is a novel support system designed for ultra-large foundation pits with large excavation areas, deep depths, and complex geological and surrounding environments. The foundation pit is scientifically divided into multiple independent units based on geological conditions, environmental sensitivity, and excavation depth. Each unit employs differentiated shotcrete and anchor support parameters, combined with a steel mesh to form the support system. This structure can be constructed simultaneously with earthwork excavation in stages, balancing safety and economy. It can flexibly adapt to the needs of different areas, effectively controlling foundation pit deformation, shortening the construction period, and reducing costs. It is suitable for ultra-large foundation pit projects such as urban core area complexes and transportation hubs, providing stable protection for underground space excavation.

[0003] A search revealed Chinese patent publication number CN202221315365.X, which discloses a shotcrete and anchor support structure, belonging to the field of shotcrete and anchor support technology. This invention addresses the problems in existing shotcrete and anchor support structures where the steel mesh makes it difficult to quickly measure the sprayed concrete thickness, leading to excessively large differences in sprayed thickness, substandard sprayed thickness, or poor bidirectional fixing effect on the concrete. This utility model includes a steel mesh laid on a slope, anchor rods that fix the steel mesh and drive them into the slope, and a sprayed concrete layer. The steel mesh includes a lower layer laid on the slope surface, multiple sets of connecting steel bars evenly spaced horizontally and vertically along the lower layer, and an upper layer of steel mesh set on each set of connecting steel bars.

[0004] The aforementioned patent mentions the following beneficial effects: "During shotcrete support, multiple sets of connecting steel bars are installed at equal intervals in both the transverse and longitudinal directions along the lower layer of steel mesh, and an upper layer of steel mesh is installed on each set of connecting steel bars, so that the laid steel mesh forms a two-way spatial laying, that is, horizontal laying along the slope surface and vertical laying perpendicular to the slope surface. By adopting a two-way laying method, the thickness of the sprayed concrete can be quickly measured through vertical laying, thereby avoiding problems such as excessive differences in spray thickness or substandard spray thickness. Moreover, the steel mesh laying method in this case can effectively achieve two-way fixation and also avoid the problem of excessive steel bar usage." However, two-way laying requires precise control of the upper and lower layers. The positional relationship between the reinforcing mesh and the connecting reinforcing bars requires higher standards for construction surveying and positioning. Improper operation can easily lead to misalignment of the reinforcing mesh, which in turn affects the stability of the support structure. Secondly, the process of adding connecting reinforcing bars and assembling upper and lower layers of reinforcing mesh is more complicated than traditional unidirectional laying, which increases on-site construction procedures and time. Especially on special working surfaces such as slopes, it may delay the overall construction progress. If workers do not operate in a standardized manner, problems such as loose connection points and deviations in the spacing of reinforcing bars may occur, requiring additional manpower for rectification later. To a certain extent, this increases the construction management cost and the difficulty of quality control. Therefore, a zoned shotcrete and anchor support structure for ultra-large foundation pits is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this application is to provide a zoned shotcrete and anchor support structure for ultra-large foundation pits, which aims to improve the problems of reduced positioning accuracy, decreased support stability, and reduced construction efficiency in the existing technology.

[0006] This application provides a zoned shotcrete and anchor support structure for ultra-large foundation pits, employing the following technical solution: A large-scale foundation pit zoned shotcrete and anchor support structure includes a slope, a positioning mechanism installed inside the slope, a fixing mechanism installed on the outer wall of the positioning mechanism, multiple water outlets fixedly connected to the inner wall of the slope, and a steel mesh fixedly connected to the rear end of the fixing mechanism. The positioning mechanism includes multiple anchor rods, the outer walls of which are fixedly connected to the inner wall of the slope. A connecting rod is slidably connected to the inner wall of each anchor rod. Multiple transmission plates are rotatably connected to the outer wall of each connecting rod. A fixing rod is rotatably connected to the other end of each transmission plate. A support plate is fixedly connected to the inner wall of each connecting rod. Multiple inclined blocks are fixedly connected to the outer wall of each connecting rod. A mounting frame is fixedly connected to the inner wall of each anchor rod. A locking component is slidably connected to the inner wall of each mounting frame. Through the above technical solution: the positioning mechanism is fixed to the slope by anchor rods, the connecting rod is pushed to make the transmission plate drive the fixed rod to open and anchor the slope, and at the same time the inclined block triggers the locking component to lock the position of the connecting rod. The fixing mechanism and the steel mesh work together to enhance the support, and the outlet drainage ensures the stability of the structure.

[0007] As a further description of the above technical solution: The locking assembly includes a second connecting rod, the outer wall of which is slidably connected to the inner wall of the mounting bracket, a spring is sleeved on the outer wall of the second connecting rod, a limit plate is fixedly connected to the top end of the second connecting rod, and a second inclined block is fixedly connected to the bottom end of the second connecting rod. Through the above technical solution: the second connecting rod slides along the inner wall of the mounting frame, the second inclined block is squeezed by the first inclined block and drives the second connecting rod to move upward and compress the spring. After the spring stores its force, it resets and pushes the second connecting rod downward so that the second inclined block and the first inclined block are tightly engaged. The limiting plate restricts the sliding range of the second connecting rod, and finally achieves the position locking of the first connecting rod.

[0008] As a further description of the above technical solution: The fixing mechanism includes sliding blocks, with two sliding blocks slidably connected to the outer wall of the anchor rod on their adjacent sides. A second fixing rod is fixedly connected to the inner wall of one of the sliding blocks, and a support rod is rotatably connected to the other end of the second fixing rod. Two turntables are fixedly connected to the outer walls of the support rods, and a fixing plate is fixedly connected to the outer walls of the two turntables. Through the above technical solution: the sliding block slides along the outer wall of the anchor rod to adjust its position, the second fixed rod moves with the sliding block and provides a fulcrum for the support rod to rotate, the support rod drives the fixed plate to rotate through the turntable, and at the same time the turntable pushes another sliding block to slide along the second fixed rod, so that the fixed plate fits the slope and works with the anchor rod to enhance the stability of the support.

[0009] As a further description of the above technical solution: The outer walls of the multiple water outlets are fitted with filter screens, and the outer walls of the multiple filter screens are fixedly connected to the inner wall of the slope. Through the above technical solution: the filter screen installed at the outlet is fixed to the inner wall of the slope. During operation, the outlet can promptly discharge the water accumulated inside the slope, avoiding the soil softening caused by water accumulation and affecting the stability of the support. The filter screen can intercept impurities such as mud and sand, preventing them from clogging the outlet, ensuring that the drainage channel is unobstructed for a long time, and ensuring the continuous and effective drainage function of the entire shotcrete support structure.

[0010] As a further description of the above technical solution: The outer wall of the steel mesh is in contact with the outer wall of the anchor rod, and the outer wall of the fixing rod is slidably connected to the inner wall of the anchor rod. Through the above technical solution: the outer wall of the steel mesh contacts the outer wall of the anchor rod, and the anchor rod provides a support and fixing point for the steel mesh, so that the steel mesh can stably cover the surface of the slope and disperse the stress of the surface soil. The outer wall of the fixing rod slides along the inner wall of the anchor rod and can extend and embed into the slope under the drive of the transmission plate, thereby enhancing the anchoring force between the anchor rod and the slope. The two work together to ensure the support effect from the perspectives of surface protection and deep anchoring.

[0011] As a further description of the above technical solution: The outer wall of the connecting rod one is slidably connected to the inner wall of the support plate, and the front end of the inclined block two is in contact with the rear end of the inclined block one; Through the above technical solution: the support plate provides internal support for the connecting rod 1 to prevent it from bending and deforming when sliding, and ensures that the connecting rod 1 can stably transmit power to drive the fixed rod 1 to move; the front end of the inclined block 2 contacts the rear end of the inclined block 1, and the inclined block 1 squeezes the inclined block 2 when it moves with the connecting rod 1, providing conditions for the locking component to trigger the locking action. The two respectively ensure the stable operation of the positioning mechanism from the perspectives of structural support and power triggering.

[0012] As a further description of the above technical solution: One end of the spring is fixedly connected to the outer wall of the mounting bracket, and the other end of the spring is fixedly connected to the bottom end of the limiting plate. The above technical solution involves fixing the two ends of the spring to the outer wall of the mounting bracket and the bottom of the limiting plate, respectively. When compressed, the spring stores force, and when reset, it pushes the connecting rod 2 downward, causing the inclined block 2 to lock the inclined block 1. At the same time, the limiting plate restricts the range of motion of the spring and the connecting rod 2, ensuring stable locking.

[0013] As a further description of the above technical solution: The inner wall of the other sliding block is slidably connected to the outer wall of the second fixed rod, and the outer walls of the two turntables are in contact with the outer wall of the other sliding block; Through the above technical solution: the inner wall of the other sliding block slides along the outer wall of the second fixed rod, and the outer wall of the turntable contacts it. When the turntable rotates with the support rod, it pushes the sliding block to move, and coordinates the adjustment of the angle of the fixed plate to ensure that it fits the slope to enhance the support.

[0014] In summary, this application includes at least one of the following beneficial technical effects: 1. In this utility model, the connecting rod 1 is pushed by an external force, which drives the transmission plate to open and anchor the fixed rod 1 to the slope; the inclined block 1 squeezes the inclined block 2 of the locking assembly, causing the connecting rod 2 to compress the spring, and the spring returns to its original position to push the inclined block 2 to lock the inclined block 1, thus locking the position of the connecting rod 1 and achieving support fixation. This ensures that the anchor rod is accurately in the designed position and angle in the borehole, guaranteeing the anchoring effect and support performance of the anchor rod, allowing the anchor rod to better exert its tensile and pull-out resistance, and forming a more effective interaction with the surrounding soil or rock mass, thereby enhancing the stability of the entire foundation pit support structure.

[0015] 2. In this invention, the sliding block slides along the anchor rod to adjust its position and contact the reinforcing mesh. An external force rotates the fixed plate, causing the turntable to rotate and press one of the sliding blocks to move along the second fixed rod, thus conforming the sliding block to the slope and enhancing the stability of the reinforcing mesh. This provides auxiliary fixing and prevents the reinforcing mesh from shifting, deforming, or shaking under the impact of shotcrete or soil deformation, which could affect its synergistic effect with the concrete and anchor rod. Fixing the reinforcing mesh avoids these problems and ensures that its role in the support structure is fully realized. Attached Figure Description

[0018] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.

[0019] Example: A zoned shotcrete and anchor support structure for an ultra-large foundation pit, referring to... Figures 1 to 3The structure includes slope 1, which serves as the protected object and installation foundation of the support structure, providing an installation carrier for various components and bearing the external pressure of the foundation pit. A positioning mechanism 2 is installed inside the slope 1 to achieve deep positioning of the slope 1 and enhance the internal stability of the slope 1. A fixing mechanism 3 is installed on the outer wall of the positioning mechanism 2. The positioning mechanism 2 penetrates into the interior of the slope 1 to provide deep fixing, while the fixing mechanism 3 provides external auxiliary support. Through the combination of internal and external support, the overall stability of the slope 1 is enhanced, and the bearing capacity of the support structure is improved. Specifically, slope 1 serves as the foundation to bear the pressure of the foundation pit and provides an installation carrier for the components. Positioning mechanism 2 penetrates deep into its interior to achieve deep positioning. Fixing mechanism 3 provides auxiliary support on the outer wall of positioning mechanism 2. Through the synergistic effect of the combination of internal and external components, the overall stability of slope 1 and the bearing capacity of the support structure are enhanced.

[0020] Multiple water outlets 4 are fixedly connected to the inner wall of the slope 1. The water outlets 4 can drain the water accumulated inside the slope 1 in time, so as to avoid the soil softening and strength reduction caused by rainwater or groundwater soaking. A steel mesh 6 is fixedly connected to the rear end of the fixing mechanism 3. The steel mesh 6 is tightly attached to the surface of the slope 1 through the fixing mechanism 3, so that the steel mesh 6 can evenly distribute the surface stress of the slope 1 and prevent the surface soil from falling off. Specifically, the outlet 4 on the inner wall of slope 1 can drain the internal water and prevent the soil from softening; the fixing mechanism 3 attaches the steel mesh 6 to the surface of slope 1 to disperse the surface stress and prevent soil from falling off. The two respectively ensure the support effect from the aspects of drainage protection and surface reinforcement.

[0021] The positioning mechanism 2 includes multiple anchor rods 21. The outer walls of the multiple anchor rods 21 are fixedly connected to the inner wall of the slope 1. As the core support component of the positioning mechanism 2, the anchor rods 21 penetrate deep into the slope 1 to transmit support force, disperse the external pressure of the slope 1 to the deep soil, and prevent the surface of the slope 1 from falling off. The inner wall of the anchor rod 21 is slidably connected to a connecting rod 22. The connecting rod 22 can move along the axis of the anchor rod 21 and drive the transmission plate 23 to move through its own sliding. It is a transmission component that transmits external force and drives the fixed rod 24 to unfold. The outer wall of the connecting rod 22 is rotatably connected to multiple transmission plates 23, which convert the linear motion of the connecting rod 22 into the radial motion of the fixed rod 24, ensuring smooth power transmission and adapting to different anchoring requirements. Specifically, in the positioning mechanism 2, the anchor rod 21 is fixed to the inner wall of the slope 1 to transmit the support force and distribute the pressure. The connecting rod 22 slides along the anchor rod 21 and converts the linear motion into the radial motion of the fixed rod 24 through the transmission plate 23, so as to achieve deep anchoring and stable support for the slope 1.

[0022] The other end of multiple transmission plates 23 is rotatably connected to a fixed rod 24. The fixed rod 24 is pushed outward of the anchor rod 21 by the transmission plates 23 and embedded into the soil of the slope 1, increasing the contact area and friction between the anchor rod 21 and the slope 1, enhancing the anchoring force, and preventing the anchor rod 21 from loosening. The inner wall of the connecting rod 22 is fixedly connected to a support plate 25, which strengthens the support of the connecting rod 22 and prevents it from bending and deforming under force. The outer wall of the connecting rod 22 is fixedly connected to multiple inclined blocks 26. When the inclined blocks 26 move with the connecting rod 22, they squeeze the inclined blocks 284, triggering the locking component 28 to act. The inner wall of the anchor rod 21 is fixedly connected to a mounting frame 27, which provides installation and sliding guidance for the locking component 28. The inner walls of multiple mounting frames 27 are slidably connected to the locking component 28. The locking component 28 works together to lock the position of the connecting rod 22, preventing it from retracting, ensuring the fixed rod 24 is continuously and stably anchored, and enhancing the reliability of the mechanism. Specifically, the transmission plate 23 drives the fixed rod 24 to expand outwards from the anchor rod 21 and embed it into the soil of the slope 1 to enhance the anchoring force. The support plate 25 supports the connecting rod 22 to prevent deformation. The inclined block 26 moves with the connecting rod 22 to trigger the locking component 28. The mounting frame 27 guides the locking component 28. Finally, the locking component 28 fixes the position of the connecting rod 22 to ensure that the fixed rod 24 is stably anchored.

[0023] Reference Figures 1 to 3 The locking assembly 28 includes a second connecting rod 281, which achieves one-way locking of the first connecting rod 22 through the cooperation of various components, preventing it from retracting after being subjected to force. The outer wall of the second connecting rod 281 is slidably connected to the inner wall of the mounting bracket 27. The second connecting rod 281 serves as the main support rod 33 of the locking assembly 28, enabling the coordinated action of various components. A spring 282 is sleeved on the outer wall of the second connecting rod 281, which provides power for subsequent reset, ensuring automatic maintenance of the locked state and rapid reset after unlocking. A limit plate 283 is fixedly connected to the top of the second connecting rod 281, which limits the maximum sliding distance of the second connecting rod 281 and prevents it from falling out of the mounting bracket 27. A second inclined block 284 is fixedly connected to the bottom of the second connecting rod 281. The inclined surface of the second inclined block 284 is adapted to the first inclined block 26, and it engages with the first inclined block 26 under the push of the spring 282, preventing the first connecting rod 22 from retracting. Specifically, in the locking assembly 28, the second connecting rod 281 slides along the inner wall of the mounting bracket 27, the sleeved spring 282 provides the reset power, the top limiting plate 283 prevents it from falling off, and the bottom inclined block 284 is adapted to the inclined block 26 and engages under the push of the spring 282 to achieve one-way locking of the first connecting rod 22 and prevent it from retracting under force.

[0024] Reference Figures 2 to 4The fixing mechanism 3 includes sliding blocks 31. Two sliding blocks 31 are slidably connected to the outer wall of the anchor rod 21 on their adjacent sides. The sliding blocks 31 slide along the outer wall of the anchor rod 21 and can be adjusted in position. The anchor rod 21 provides guidance for the sliding blocks 31. The two work together to adjust the position of the fixing mechanism 3. A fixing rod 32 is fixedly connected to the inner wall of one of the sliding blocks 31. The sliding block 31 fixes the fixing rod 32 and drives it to move. A support rod 33 is rotatably connected to the other end of the fixing rod 32. The fixing rod 32 provides a fulcrum for the support rod 33. The support rod 33 can rotate around the fixing rod 32, driving the subsequent components to achieve the fixing effect. Two turntables 34 are fixedly connected to the outer wall of the support rod 33. The support rod 33 provides the installation foundation and support force for the turntables 34, so that the turntables 34 rotate around the support rod 33 as the axis. A fixing plate 35 is fixedly connected to the outer wall of the two turntables 34. The turntables 34 are rotated by external force by moving the fixing plate 35, which enhances the stability of the fixing mechanism 3 and the steel mesh 6. Specifically, in the fixing mechanism 3, the sliding block 31 slides along the anchor rod 21 to adjust its position, which drives the second fixing rod 32 to move. The second fixing rod 32 provides a rotation fulcrum for the support rod 33. The support rod 33 drives the fixing plate 35 to rotate through the turntable 34, which enhances the stability with the steel mesh 6 and realizes the auxiliary fixing of the slope 1.

[0025] Reference Figures 2 to 4 Multiple outlets 4 are fitted with filter screens 5 on their outer walls. The outlets 4 are responsible for draining water accumulated on the slope 1. The filter screens 5 can intercept mud and sand impurities to prevent the outlets 4 from clogging. The outer walls of multiple filter screens 5 are fixedly connected to the inner wall of the slope 1. The filter screens 5 are fixed to the inner wall of the slope 1 to provide protection for the outlets 4 and prevent water accumulation on the slope 1 from causing hidden dangers. The outer wall of the steel mesh 6 is in contact with the outer wall of the anchor rod 21. The anchor rod 21 provides a support and fixing point for the steel mesh 6. The steel mesh 6 covers the surface of the slope 1 with the support of the anchor rod 21 to disperse the surface stress. The outer wall of the fixing rod 24 is slidably connected to the inner wall of the anchor rod 21. The anchor rod 21 provides sliding space and guidance for the fixing rod 24. The outer wall of the connecting rod 22 is slidably connected to the inner wall of the support plate 25. The support plate 25 provides internal support for the connecting rod 22 to prevent it from shaking or shifting when sliding. Specifically, the filter screen 5 installed at the outlet 4 is fixed to the inner wall of the slope 1 to drain water and prevent blockage, thus avoiding the risk of water accumulation; the steel mesh 6 is supported by the anchor rod 21 to cover the surface of the slope 1 and disperse stress, the fixing rod 24 slides along the inner wall of the anchor rod 21, and the connecting rod 22 is supported by the support plate 25 to prevent displacement, together ensuring the stability of the support structure.

[0026] The front end of the second inclined block 284 contacts the rear end of the first inclined block 26. The first inclined block 26 moves with the first connecting rod 22 to press the second inclined block 284, triggering the locking component 28 to act. One end of the spring 282 is fixedly connected to the outer wall of the mounting frame 27, and the other end of the spring 282 is fixedly connected to the bottom end of the limiting plate 283. One end of the spring 282 is fixed to the outer wall of the mounting frame 27, and the other end is fixed to the bottom end of the limiting plate 283. The mounting frame 27 and the limiting plate 283 provide a fixed support point for the spring 282. The inner wall of another sliding block 31 is slidably connected to the outer wall of the second fixed rod 32. The second fixed rod 32 provides a sliding track for the sliding block 31. The sliding block 31 can move along the second fixed rod 32 to adjust its position. The outer walls of the two turntables 34 are in contact with the outer wall of the other sliding block 31. When the turntables 34 rotate, they can push the sliding block 31 to move along the second fixed rod 32 to fix the steel mesh 6. Specifically, the first inclined block 26 moves with the first connecting rod 22, pressing the second inclined block 284 to trigger locking. The spring 282 is fixed between the mounting bracket 27 and the limiting plate 283 to provide support. The other sliding block 31 slides along the second fixed rod 32, and the turntable 34 rotates to push it to move, together achieving locking and fixing of the steel mesh 6.

[0027] Working principle: When anchor rod 21 needs to be positioned, multiple anchor rods 21 are first fixed to the inner wall of slope 1 as a basic support structure. External force pushes connecting rod 22 to slide along the inner wall of anchor rod 21, and multiple transmission plates 23 on its outer wall move together. The other end of the transmission plate 23 drives the fixing rod 24 to be pushed outward of anchor rod 21, so that the fixing rod 24 is embedded in the interior of slope 1, enhancing the connection stability between anchor rod 21 and slope 1. At the same time, the support plate 25 on the inner wall of connecting rod 22 can help support the internal structure and prevent connecting rod 22 from sliding excessively. During the sliding process of connecting rod 22, the inclined block 26 on its outer wall presses the inclined block 284 of locking assembly 28, forcing the inclined block 284 to drive connecting rod 281 to slide upward along the inner wall of mounting frame 27. At this time, the spring 282 sleeved on the outer wall of connecting rod 281 is compressed and stores force, while the limiting plate 283 can limit the sliding range of connecting rod 281 and prevent it from falling off the mounting frame 27. When connecting rod 22 moves to the designated position, spring 282 resets and pushes connecting rod 281 down, so that inclined block 284 and inclined block 26 fit tightly together, locking the position of connecting rod 22 and preventing it from retracting, thus achieving stable support and positioning of slope 1.

[0028] When it is necessary to fix the steel mesh 6, move the two sliding blocks 31 to slide on the outer wall of the anchor rod 21, so that the sliding blocks 31 fit against the steel mesh 6. Then, turn the fixing plate 35 to rotate the turntable 34, which will squeeze one of the sliding blocks 31 to slide along the fixing rod 32, so that the two sliding blocks 31 are clamped on the outer wall of the anchor rod 21, thereby fixing the steel mesh 6. This prevents the steel mesh 6 from being displaced, deformed or shaken under the impact of shotcrete or soil deformation, which would affect its working effect with the concrete and the anchor rod 21.
