Description
Technical Field
[0001] The present application relates to the technical field of ground-anchored wall construction, and in particular to a method for controlling the verticality of a prefabricated ground-anchored wall during hoisting in a mud environment. Background Art
[0002] The ground-connected wall is constructed by using trenching machinery on the ground, along the peripheral axis of the deep excavation project, under the condition of mud wall protection, to dig a narrow and long trench. After the trench is cleared, a steel cage is suspended in the trench, and then underwater concrete is poured using the conduit method to build a unit trench section. This is done section by section, and finally a continuous reinforced concrete wall is built underground. This structure not only has load-bearing capacity, but also can effectively prevent groundwater infiltration and ensure the safety of the project. At this stage, prefabricated ground-connected walls have appeared. The upper end of the prefabricated ground-connected wall is opened with a through hole. When lowering, it only needs to be placed in the trench by a crane through the through hole on the ground-connected wall, and then concrete is poured into the gap between the ground-connected wall and the trench.
[0003] Considering that there will be mud in the trench, when placing the ground tie wall, it cannot be guaranteed that the ground tie wall is vertical after being placed at the bottom of the trench. At this stage, the verticality of the ground tie wall placed in the trench is detected by using an inclinometer, and the crane is used to pull and adjust it.
[0004] However, simply adjusting by crane traction requires repeated lifting and lowering, which takes too much time. Summary of the invention
[0005] In view of the shortcomings of the prior art, the purpose of this application is to provide a method for controlling the verticality of a prefabricated ground-anchored wall during hoisting in a mud environment to solve the technical problem that it is difficult to control the verticality when lowering the ground-anchored wall.
[0006] The above-mentioned object of the present application is achieved through the following technical solutions: A method for controlling the verticality of hoisting of an assembled ground-connected wall in a mud environment, comprising the following steps; S1. Use a crane to hang the prefabricated ground connection wall above the trench, and then slowly lower it into the trench. S2, setting a clamping device, tying the clamping device with a rope, and allowing it to slide down into the groove along the flange of the prefabricated ground connecting wall; S3. Adjust the cylinders on both sides of the clamping device and coordinate with the crane to make the prefabricated ground connection wall vertical in the groove; S4, the verticality of the lowered prefabricated ground-connected wall is tested by using an inclinometer. If the verticality does not meet the standard, the cylinder and the suspension rope are adjusted; S5. If the verticality meets the standard, start to lower the filling water bags on both sides of the prefabricated ground connection wall. After lowering to the bottom, water is injected into the filling water bags to expand them. The filling water bags squeeze the prefabricated ground connection and the side wall of the groove to provide support. S6, when the water filling inside the water bag is completed, the clamping device starts to be recovered; S7. After the clamping device leaves the trench, concrete is poured in the gap between the trench and the prefabricated ground connection wall, and the initial setting is waited for, and the filled water bag is recovered to complete the construction.
[0007] By adopting the above technical solution, first, use a crane to vertically lift the prefabricated ground ditch wall from the ground or stacking area to the top of the trench. The crane operator needs to ensure that the lifting process is smooth to prevent the prefabricated ground ditch wall from tilting or colliding during the lifting process. Then, slowly lower the prefabricated ground ditch wall into the trench until its bottom contacts the bottom of the trench.
[0008] Before or during the lowering of the prefabricated ground connection wall into the groove, prepare the clamping device. The clamping device includes a positioning rod, a clamping rod, an extrusion cylinder, and a suspension structure. The suspension structure of the clamping device is connected to a crane or other lifting equipment through a rope. Then, the clamping device is placed above the prefabricated ground connection wall, and the rope is slowly released so that the clamping device slides down into the groove along the flange of the prefabricated ground connection wall. During this process, it is necessary to ensure that the clamping device can slide smoothly and does not collide violently with the prefabricated ground connection wall.
[0009] After the clamping device completely falls into the groove and clamps the prefabricated ground connection wall, it is adjusted through the adjustment cylinders on both sides of the clamping device. The adjustment cylinder and the crane need to work together to fine-tune the position and posture of the prefabricated ground connection wall to ensure that its verticality meets the design requirements. During the adjustment process, it is necessary to use measuring tools such as inclinometers to monitor the verticality of the prefabricated ground connection wall in real time for timely adjustment.
[0010] After completing the initial adjustment, use an inclinometer to accurately test the verticality of the prefabricated ground-connected wall. If the verticality does not meet the standard, continue to fine-tune it by adjusting the cylinder and the suspension rope until it meets the design requirements. This step is a key link to ensure the installation quality of the prefabricated ground-connected wall.
[0011] After the verticality of the prefabricated diaphragm wall meets the standard, start to lower the filling water bag on both sides of the prefabricated diaphragm wall. The filling water bag needs to be customized according to the size and shape of the prefabricated diaphragm wall to ensure that it can fit tightly and support the prefabricated diaphragm wall. After lowering the filling water bag to the predetermined position, start to fill the filling water bag with water. As water is injected, the filling water bag gradually expands and squeezes the gap between the prefabricated diaphragm wall and the side wall of the trench, thereby providing the necessary support force.
[0012] After the filling water bag is filled with water and reaches the predetermined pressure, the clamping device is recovered. The clamping device is separated from the prefabricated ground connection wall and completely out of the groove by releasing the rope connection and slowly lifting the clamping device. During the recovery process, it is necessary to ensure that the clamping device does not collide with the filling water bag or the prefabricated ground connection wall.
[0013] After the clamping device leaves the trench, pour concrete in the gap between the trench and the prefabricated ground wall. During the pouring process, ensure that the concrete is densely filled and there are no obvious bubbles or voids. After the initial setting of the concrete (the specific time depends on the type of concrete and construction conditions), start to recover the filled water bag. Remove the filled water bag from the trench by draining the water in the water bag and releasing the fixing device.
[0014] Furthermore, the clamping device includes a positioning column and a clamping rod fixedly connected to both ends of the positioning column, an adjusting cylinder is fixedly provided on the relatively outward ends of the clamping rods at both ends, the output end of the adjusting cylinder faces the end away from the clamping rod, through holes are horizontally opened on the clamping rods at both ends, and adjusting rods plugged into the clamping rods are provided in the through holes of the clamping rods, a fixing device is provided on the adjusting rod, the positioning device includes a gear rack on the adjusting rod and a positioning groove on the adjusting rod that vertically penetrates the clamping rod, the gear rack is fixedly connected to the adjusting rod, a fixing rod is plugged into the positioning groove, and teeth are fixedly provided on the bottom end of the fixing rod.
[0015] By adopting the above technical scheme, after the prefabricated ground connection wall is placed in the groove, the adjusting rods on the clamping rods at both ends are adjusted according to the width of the flange of the prefabricated ground connection wall. After the adjustment is completed, the fixing rod at the upper end of the adjusting rod is inserted into the positioning groove. At this time, the teeth at the bottom of the fixing rod are engaged with the teeth bar on the adjusting rod to fix the adjusting rod. At this time, the distance between the two ends is adjusted, and then the clamping rods at both ends are tied with ropes. Then, the flange of the prefabricated ground connection wall is aligned through the clamping rods at both ends to let it slowly fall to the bottom of the groove. After the inclination of the ground connection wall is detected by the inclinometer, the gas rod is adjusted (wireless control or wired connection) to make it against the side wall of the groove, so that the prefabricated ground connection wall at the bottom receives a reaction force, and is adjusted in cooperation with the lifting rope on the crane. Since there are auxiliary equipment at the bottom at this time, the vertical adjustment can be completed more quickly.
[0016] Furthermore, a vertical plate perpendicular to the ground is provided on the end of the adjusting rod away from the adjusting cylinder, an adjusting block is fixedly provided on the end of the vertical plate away from the adjusting rod, an abutment rod is provided on the end of the adjusting block away from the vertical plate, and sliding wheels are rotatably provided on both the upper and lower ends of the abutment rod.
[0017] By adopting the above technical solution, in order to avoid friction with the prefabricated ground connection wall when the clamping device is lowered into the groove, in the present application, an abutment rod and a sliding wheel are arranged between the two adjusting rods, so that when the clamping device is lowered, the friction between the sliding wheel and the side wall of the prefabricated ground connection wall can be reduced, and the lowering speed can be accelerated.
[0018] Furthermore, the middle part of the abutment rod is rotatably connected to the adjustment block, and a horizontal column is extended from the upper end of the abutment rod toward the vertical pole, and the horizontal column is perpendicular to the abutment rod.
[0019] By adopting the above technical solution, considering that after determining the width of the flange on the prefabricated floor connecting wall, and then adjusting the distance between the adjustment rods on both sides, when placing the sliding wheels on both sides on the prefabricated floor connecting wall, it is necessary to be very accurate to lower them. In order to facilitate placement, the present application connects the abutment rod to the adjustment block through rotation, and extends a horizontal column from the abutment rod. When placing, the lower end of the abutment rod can be opened first to present an eight-shaped shape, and then placed on the flange on the prefabricated floor connecting wall. At this time, due to the expanded placement range, the placement can be easily completed. During the lowering process, the final width is the same as the setting of the horizontal column, so the eight-shaped abutment rods on both sides will become parallel.
[0020] Furthermore, a compression spring is provided between the horizontal column and the adjusting block, one end of the compression spring is fixedly connected to the vertical pole, and the other end of the compression spring is fixed to the abutment rod.
[0021] By adopting the above technical solution, in order to place the clamping device directly during placement, a compression spring is arranged between the horizontal column and the adjustment block in the present application. Before placement, the compression spring will compress the abutment rod, thereby causing it to automatically change into an eight-shaped shape.
[0022] Furthermore, an abutment plate is provided between the adjusting rod and the vertical upright plate, the abutment plate is fixedly connected between the adjusting rods, a buffer spring is provided between the vertical upright plate and the abutment plate, one end of the buffer spring is fixedly connected to the vertical upright plate and the other end is fixedly connected to the abutment plate, and the buffer spring is evenly arranged around the vertical upright plate and the abutment plate.
[0023] By adopting the above technical solution, when the clamping device adjusts the prefabricated ground connecting wall in the groove, the adjusting cylinders on both sides are adjusted separately. If the operator accidentally starts the adjusting cylinders at both ends at the same time, the clamping rods on both sides will be squeezed at the same time, thereby squeezing the equipment between the detection rods on both sides. Although the operator can close it immediately, the impact still exists. Therefore, in this application, a buffer spring is arranged between the vertical plate and the abutment plate, so that when the operator makes an operating error, the buffer spring can play a buffering role.
[0024] Furthermore, a hanging hammer device is provided on the clamping rod at both ends, the hanging hammer device has a lifting ring and a vertical rod fixedly connected to the lower end of the lifting ring, plug-in strips are provided at both ends of the vertical rod, the lower ends of the plug-in strips at both ends are guided inward and inclined, an extrusion spring is fixedly provided between the vertical rod and the plug-in strip, the extrusion springs are evenly provided on the four corners of the vertical rod and the plug-in strip, a plug-in hole is provided on the clamping rod, and limiting grooves provided on the clamping rod are provided around the plug-in hole, and the plug-in strips at both ends are clamped with the lower ends and the limiting grooves.
[0025] By adopting the above technical scheme, a variety of ways of bundling and fixing can be provided through the lifting ring. At the same time, considering that there will be silt and sand in the groove, in order to facilitate installation and disassembly, in this application, plug-in strips are set on both sides of the vertical rod fixedly connected at the lower end of the lifting ring, and an extrusion spring is set between the two. When fixing the lifting ring on the clamping rod, it is only necessary to press downward. As the lower ends of the plug-in strips on both sides are obliquely plugged into the plug-in holes, when they reach the limit groove, the extrusion spring will reset to allow the plug-in strip to be clamped in the limit groove and fixed. At the same time, when disassembling, it is only necessary to press the plug-in strips at both ends and then pull them upward to complete the disassembly, thereby facilitating installation and disassembly.
[0026] Furthermore, the plug hole is a square from top to bottom.
[0027] By adopting the above technical solution, the purpose of this design is to fix the connector by inserting the connector strip into the connector hole horizontally or vertically.
[0028] Furthermore, a buffer layer is provided on the output end of the regulating cylinder, and the buffer layer is plugged into the output end of the regulating cylinder.
[0029] By adopting the above technical solution, considering that the adjusting cylinder needs to be adjusted many times and the side wall of the groove is not smooth, a buffer layer is provided at the output end of the adjusting cylinder to prevent the cylinder from contacting the groove, thereby increasing the service life of the adjusting cylinder.
[0030] Furthermore, the buffer layer is made of flexible rubber.
[0031] In summary, the present application includes at least one of the following beneficial technical effects: 1. Through the cooperation of the adjusting rod and the toothed bar, the distance between the clamping rods at both ends can be flexibly adjusted according to the width of the flange of the prefabricated ground connection wall, and precise positioning can be achieved through the engagement of the fixed rod and the toothed bar to ensure that the clamping device can firmly clamp the prefabricated ground connection wall. With the help of the wireless or wired control of the inclinometer and the adjusting cylinder, the verticality of the prefabricated ground connection wall can be accurately adjusted to improve the construction accuracy and efficiency.
[0032] 2. The abutment rod and sliding wheel are set between the adjustment rods, which effectively reduces the friction between the clamping device and the side wall of the prefabricated ground-connected wall during the lowering process, which not only protects the surface of the prefabricated ground-connected wall, but also speeds up the lowering speed. The abutment rod is designed with an adjustment block and a horizontal column, making it more convenient and quick to place. 3. A buffer spring is arranged between the vertical plate and the abutment plate, which can effectively alleviate the sudden squeezing between the clamping rods caused by operational errors, protect the safety of equipment and personnel, and adjust the buffer layer design at the output end of the cylinder to avoid direct contact between the cylinder and the groove side wall, thereby extending the service life of the cylinder.
[0033] 4. The design of the hanging hammer device adopts a combination of plug-in strips and extrusion springs, making the installation and removal of the lifting ring simple and quick, without the need for complicated tools or operations, thus improving construction efficiency. The design of the plug-in hole and the limit slot ensures that the lifting ring is firmly fixed on the clamping rod, while facilitating removal and reuse. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0036] The present application is further described in detail below with reference to the accompanying drawings.
[0037] Example, see Figure 1A method for controlling the verticality of a prefabricated ground-connected wall in a mud environment comprises the following steps: S1, using a crane to hang a prefabricated ground-connected wall 4 above a groove 5, and then slowly lowering it into the groove 5; S2, setting a clamping device 1, tying the clamping device 1 with a rope, and letting it slide down into the groove 5 along with the flange of the prefabricated ground-connected wall 4; S3, adjusting the cylinders 13 on both sides of the clamping device 1, and coordinating the adjusting cylinders 13 and the crane to make the prefabricated ground-connected wall 4 vertical in the groove 5; S4, then using an inclinometer to detect the verticality of the lowered prefabricated ground-connected wall 4, if it is vertical, If the straightness does not meet the standard, continue to adjust the cylinder 13 and the suspension rope; S5, if the verticality meets the standard, start to lower the filling water bags on both sides of the prefabricated ground connection wall 4, and after lowering to the bottom, fill the filling water bags with water to expand them, and squeeze the prefabricated ground connection and the side walls of the groove 5 through the filling water bags to provide support; S6, after the filling water bags are filled with water, start to recycle the clamping device 1; S7, after the clamping device 1 leaves the groove 5, start to pour concrete in the gap between the groove 5 and the prefabricated ground connection wall 4, wait for initial setting, recycle the filling water bags, and complete the construction.
[0038] First, use a crane to vertically lift the prefabricated ground connection wall 4 from the ground or stacking area to the top of the groove 5. The crane operator needs to ensure that the lifting process is smooth to prevent the prefabricated ground connection wall 4 from tilting or colliding during the lifting process. Then, slowly lower the prefabricated ground connection wall 4 into the groove 5 until its bottom contacts the bottom of the groove 5. Before or during the lowering of the prefabricated ground connection wall 4 into the groove 5, prepare the clamping device 1 and connect the suspension structure of the clamping device 1 to the crane or other lifting equipment through a rope. Then, place the clamping device 1 above the prefabricated ground connection wall 4, and slowly release the rope so that the clamping device 1 slides down into the groove 5 along the flange of the prefabricated ground connection wall 4. During this process, it is necessary to ensure that the clamping device 1 can slide smoothly and does not collide violently with the prefabricated ground connection wall 4. After the clamping device 1 completely falls into the groove 5 and clamps the prefabricated ground connection wall 4, it is adjusted by the adjusting cylinders 13 on both sides of the clamping device 1. The adjusting cylinder 13 and the crane need to work together to fine-tune the position and posture of the prefabricated ground-connected wall 4 to ensure that its verticality meets the design requirements. During the adjustment process, it is necessary to use measuring tools such as inclinometers to monitor the verticality of the prefabricated ground-connected wall 4 in real time for timely adjustment. After completing the preliminary adjustment, use an inclinometer to accurately detect the verticality of the prefabricated ground-connected wall 4. If the verticality does not meet the standard, continue to fine-tune it by adjusting the cylinder 13 and the suspension rope until it meets the design requirements. This step is a key link in ensuring the installation quality of the prefabricated ground-connected wall 4.
[0039] After the verticality of the prefabricated ground-connected wall 4 reaches the standard, start to place filling water bags on both sides of the prefabricated ground-connected wall 4. The filling water bags need to be customized according to the size and shape of the prefabricated ground-connected wall 4 to ensure that they can fit tightly and support the prefabricated ground-connected wall 4. After the filling water bags are placed in the predetermined position, start to fill the filling water bags with water. As the water is injected, the filling water bags gradually expand and squeeze the gap between the prefabricated ground-connected wall 4 and the side wall of the groove 5, thereby providing the necessary support force.
[0040] After the filling water bag is filled with water and reaches the predetermined pressure, the clamping device 1 is recovered. The clamping device 1 is separated from the prefabricated ground connection wall 4 and completely leaves the groove 5 by releasing the rope connection and slowly lifting the clamping device 1. During the recovery process, it is necessary to ensure that the clamping device 1 does not collide with the filling water bag or the prefabricated ground connection wall 4.
[0041] After the clamping device 1 leaves the groove 5, concrete is poured in the gap between the groove 5 and the prefabricated ground connecting wall 4. During the pouring process, it is necessary to ensure that the concrete is densely filled and has no obvious bubbles or voids. After the concrete is initially set (the specific time depends on the concrete type and construction conditions), the filled water bag is recovered. 6 The filled water bag is removed from the groove 5 by draining the water in the water bag and releasing the fixing device.
[0042] In this embodiment, refer to Figure 2 , Figure 3 as well as Figure 4 The clamping device 1 includes a positioning column and a clamping rod 12 fixedly connected to both ends of the positioning column. An adjusting cylinder 13 is fixedly arranged on the end of the clamping rod 12 at both ends facing outward. The output end of the adjusting cylinder 13 faces the end away from the clamping rod 12. Through holes are horizontally opened on the clamping rods 12 at both ends. Adjusting rods 14 inserted into the clamping rod 12 are arranged in the through holes of the clamping rod 12. A fixing device is arranged on the adjusting rod 14. The positioning device includes a gear rack 15 on the adjusting rod 14 and a positioning groove 17 on the adjusting rod 14 that vertically penetrates the clamping rod 12. The gear rack 15 is fixedly connected to the adjusting rod 14. A fixing rod 16 is inserted in the positioning groove 17. The bottom end of the fixing rod 16 is fixedly provided with gears.
[0043] After the prefabricated ground connecting wall 4 is placed in the groove 5, the adjusting rods 14 on the clamping rods 12 at both ends are adjusted according to the width of the flange of the prefabricated ground connecting wall 4. After the adjustment is completed, the fixing rod 16 at the upper end of the adjusting rod 14 is inserted into the positioning groove 17. At this time, the teeth at the bottom of the fixing rod 16 are engaged with the toothed rack 15 on the adjusting rod 14 to fix the adjusting rod 14. At this time, the distance between the two ends is adjusted, and then the clamping rods 12 at both ends are tied with ropes, and then the flanges of the prefabricated ground connecting wall 4 are aligned through the clamping rods 12 at both ends to allow it to slowly fall to the bottom of the groove 5. After the inclination of the ground connecting wall is detected by the inclinometer, the gas rod is adjusted (wireless control or wired connection) to make it abut against the side wall of the groove 5, so that the prefabricated ground connecting wall 4 at the bottom receives a reaction force, and then the suspension rope on the crane is used for adjustment. Since there are auxiliary equipment at the bottom at this time, the vertical adjustment can be completed more quickly.
[0044] In this embodiment, a vertical plate 2 perpendicular to the ground is provided on the end of the adjusting rod 14 away from the adjusting cylinder 13, an adjusting block 21 is fixedly provided on the end of the vertical plate 2 away from the adjusting rod 14, an abutment rod 22 is provided on the end of the adjusting block 21 away from the vertical plate 2, and sliding wheels 23 are rotatably provided on the upper and lower ends of the abutment rod 22. In order to avoid friction with the prefabricated ground connection wall 4 when the clamping device 1 is lowered into the groove 5, in this application, by arranging the abutment rod 22 and the sliding wheel 23 between the two adjusting rods 14, when the clamping device 1 is lowered, the friction can be reduced through the sliding wheel 23 and the side wall of the prefabricated ground connection wall 4, and the lowering speed can be accelerated.
[0045] In this embodiment, the middle part of the abutment rod 22 is rotatably connected to the adjustment block 21, and a horizontal column 27 is extended from the upper end of the abutment rod 22 toward the vertical pole, and the horizontal column 27 is perpendicular to the abutment rod 22. Considering that after the flange width on the prefabricated ground connecting wall 4 is determined, and then the distance between the adjusting rods 14 on both sides is adjusted, when the sliding wheels 23 on both sides are placed on the prefabricated ground connecting wall 4, it is necessary to be very accurate to lower it. In order to facilitate placement, the present application is through the abutment rod 22 being rotatably connected to the adjustment block 21, and a horizontal column 27 is extended on the abutment rod 22. When placing, the lower end of the abutment rod 22 can be opened first to present an eight-shaped shape, and then it can be placed on the flange on the prefabricated ground connecting wall 4. At this time, due to the expanded placement range, the placement can be easily completed. During the lowering process, the final width is the same as the setting of the horizontal column 27, so the eight-shaped abutment rods 22 on both sides will become parallel.
[0046] In this embodiment, a squeezing spring 3726 is arranged between the horizontal column 27 and the adjusting block 21. One end of the squeezing spring 3726 is fixedly connected to the vertical pole, and the other end is fixed to the abutment rod 22. In order to be able to place the clamping device 1 directly during the placement process, the squeezing spring 3726 is arranged between the horizontal column 27 and the adjusting block 21 in the present application. Before placement, the squeezing spring 3726 will squeeze the abutment rod 22, thereby allowing it to automatically become an eight-shaped shape.
[0047] In this embodiment, an abutment plate 24 is provided between the adjustment rod 14 and the vertical upright plate 2, and the abutment plate 24 is fixedly connected between the adjustment rod 14. A buffer spring 28 is provided between the vertical upright plate 2 and the abutment plate 24, and one end of the buffer spring 28 is fixedly connected to the vertical upright plate 2 and the other end is fixedly connected to the abutment plate 24. The buffer spring 28 is evenly arranged around the vertical upright plate 2 and the abutment plate 24. Considering that when the clamping device 1 in the groove 5 adjusts the prefabricated ground connecting wall 4, the adjusting cylinders 13 on both sides are adjusted separately. If the operator accidentally starts the adjusting cylinders 13 at both ends at the same time, the two will squeeze the clamping rods 12 on both sides at the same time, thereby squeezing the equipment between the detection rods on both sides. Although the operator can close it immediately, the impact still exists. Therefore, in this application, by arranging a buffer spring 28 between the vertical upright plate 2 and the abutment plate 24, when the operator makes an operating error, the buffer spring 28 can play a buffering role.
[0048] In this embodiment, a hanging hammer device is provided on the clamping rods 12 at both ends, a hanging hammer device hanging ring 3 and a vertical rod 31 fixedly connected to the lower end of the hanging ring 3, plug-in strips 32 are provided at both vertical ends, and the lower ends of the plug-in strips 32 at both ends are guided inward and tilted, and an extrusion spring 3726 is fixedly provided between the vertical rod 31 and the plug-in strip 32, and the extrusion spring 3726 is evenly arranged on the four corners of the vertical rod 31 and the plug-in strip 32, and a plug-in hole 34 is provided on the clamping rod 12, and a limiting groove 35 is provided around the plug-in hole 34. The plug-in strips 32 at both ends and the lower end are clamped with the limiting groove 35, and a variety of ways of bundling and fixing can be provided through the hanging ring 3. At the same time, considering that there will be silt and sand in the groove 5, in order to facilitate installation and disassembly, in this application, plug-in strips 32 are set on both sides of the vertical rod 31 fixedly connected at the lower end of the lifting ring 3, and an extrusion spring 3726 is set between the two. When fixing the lifting ring 3 on the clamping rod 12, you only need to press down. As the lower ends of the plug-in strips 32 on both sides are obliquely inserted into the plug-in holes 34, when they reach the limit groove 35, the extrusion spring 3726 will reset to allow the plug-in strip 32 to be clamped in the limit groove 35 and fixed. At the same time, when disassembling, you only need to press the plug-in strips 32 at both ends and then pull them upwards to complete the disassembly, which is convenient for installation and disassembly.
[0049] In this embodiment, the plug hole 34 is a square from top to bottom. The purpose of this design is that the plug strip 32 can be plugged into the plug hole 34 no matter horizontally or vertically to fix it.
[0050] In this embodiment, a buffer layer 18 is provided on the output end of the adjusting cylinder 13. The buffer layer 18 is inserted into the output end of the adjusting cylinder 13. Considering that the adjusting cylinder 13 needs to be adjusted multiple times, and the side wall of the groove 5 is not smooth, a buffer layer 18 is provided at the end of the output end of the adjusting cylinder 13 to prevent the cylinder from contacting the groove 5, thereby increasing the service life of the adjusting cylinder 13. The buffer layer 18 is made of flexible rubber.
[0051] Specific implementation process: Through the cooperation of the adjusting rod 14 and the gear bar 15, the distance between the clamping rods 12 at both ends can be flexibly adjusted according to the width of the flange of the prefabricated ground connection wall 4, and precise positioning can be achieved through the engagement of the fixing rod 16 and the gear, ensuring that the clamping device 1 can firmly clamp the prefabricated ground connection wall 4. With the help of the wireless or wired control of the inclinometer and the adjusting cylinder 13, the verticality of the prefabricated ground connection wall 4 can be accurately adjusted to improve the construction accuracy and efficiency.
[0052] An abutment rod 22 and a sliding wheel 23 are arranged between the adjustment rods 14, which effectively reduces the friction between the clamping device 1 and the side wall of the prefabricated ground tie wall 4 during the lowering process, not only protecting the surface of the prefabricated ground tie wall 4, but also accelerating the lowering speed.
[0053] The abutment rod 22 is designed with an adjustment block 21 and a horizontal column 27, making it more convenient and quick to place and improving construction efficiency. A buffer spring 28 is arranged between the vertical plate 2 and the abutment plate 24, which can effectively alleviate the sudden squeezing between the clamping rods 12 caused by operational errors and protect the safety of equipment and personnel. The buffer layer 18 at the output end of the adjusting cylinder 13 is designed to avoid direct contact between the cylinder and the side wall of the groove 5, thereby extending the service life of the cylinder. The design of the hanging hammer device adopts a combination of a plug strip 32 and an extrusion spring 3726, which makes the installation and disassembly of the lifting ring 3 simple and quick, without complicated tools or operations, thereby improving construction efficiency. The design of the plug hole 34 and the limit groove 35 ensures that the lifting ring 3 is firmly fixed on the clamping rod 12, while facilitating disassembly and reuse.
[0054] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
