Description

Technical Field

[0001] The invention relates to the technical field of geotechnical foundation engineering, and in particular to an assembled wall guide device for underground continuous wall construction and a method thereof. Background Art

[0002] Prefabricated steel guide walls play a multi-faceted role in underground engineering construction. First, they play a key role in construction guidance. Whether it is providing precise guidance for trenching equipment in underground continuous wall construction to ensure the accurate position of underground structures, just like accurately positioning the construction of subway station enclosure structures, or guiding the correct direction of pipelines in underground pipeline laying, they all ensure the accuracy of the project and avoid conflicts with other underground facilities. Secondly, they perform well in terms of trench wall stability. With their high strength and rigidity, they can effectively resist lateral soil pressure, especially in areas with soft soil or high groundwater levels, such as coastal silty soil areas, to prevent the collapse of the trench wall soil. At the same time, as a mud storage container, they maintain the stability of the mud liquid level and balance the soil pressure and water pressure. Furthermore, it can carry the load of construction equipment, support the weight of trenching equipment and the load of lifting equipment, ensure that the construction equipment will not damage the trench wall soil during operation, and provide a safe and stable environment for construction. In addition, its advantages of factory prefabrication and rapid installation significantly improve construction efficiency. Standardized factory production ensures stable quality and precision. Rapid on-site installation omits time such as on-site concrete curing, speeds up construction progress, and is of great significance for projects with strict construction period requirements.

[0003] The on-site installation construction process of prefabricated steel guide walls is a complex and delicate project. The following are the main steps of the process:

[0004] 1. Construction preparation: Ensure that the construction site is flat and free of obstacles, and prepare necessary construction equipment and tools, such as cranes, welders, bolts, etc.; check whether the components of the prefabricated steel guide wall are complete and undamaged, and ensure that the size and specifications of the components meet the design requirements.

[0005] 2. Positioning and layout: Determine the installation position and elevation of the prefabricated steel guide wall according to the construction drawings and actual on-site conditions.

[0006] 3. Component lifting and positioning: Use a crane to lift the components of the prefabricated steel guide wall, paying attention to maintaining the balance and stability of the components.

[0007] 4. Connection and fixing: Use welding machine to permanently connect the components of prefabricated steel guide wall.

[0008] 5. Inspection and acceptance: Conduct a comprehensive inspection of the installation quality of the prefabricated steel guide wall, including location, elevation, connection points, etc.

[0009] The Chinese patent with publication number CN212358270U discloses a prefabricated guide wall, which mainly solves the problem of prefabricating unit components and then assembling and splicing the unit components to obtain guide wall components of different shapes, so that the shape of the guide wall can be flexibly adjusted according to needs. Since the guide wall is prefabricated into unit components, it can save storage space and facilitate transportation. Under the same lifting capacity, the plane size of the guide wall can also be increased, which helps to improve the integrity and stability of the guide wall.

[0010] A Chinese patent with publication number CN211596742U discloses a prefabricated guide wall for an underground continuous wall, which mainly solves the problem that the existing guide wall has a slow construction progress and cannot be used multiple times.

[0011] A Chinese patent with publication number CN218952156U discloses a prefabricated guide wall for an underground continuous wall, which mainly solves the problem of sequentially assembling a first curved plate and a second curved plate, and locking the plate by the cooperation between the second curved plate and a locking block, thereby forming a closed hole position, which provides good protection for the hole opening and replaces the traditional integrated pouring method. The first curved plate and the second curved plate can be disassembled and reused, which ensures construction accuracy while greatly saving construction costs and is in line with the sustainable development strategy.

[0012] However, in the prior art, suitable lifting equipment is mostly used to lift the guide wall and initially put it into position, the position and verticality are checked and adjusted with the help of instruments, the guide wall plate is positioned and installed with manual assistance, and then bolts are manually connected and tightened in sequence, or welded for fixation. However, in these construction processes, the role played by the equipment is single, and the role of manual assistance is greater than that of mechanical equipment, which can easily lead to an increase in labor costs and a significant extension of the construction period. The splicing speed is slow and ordinary card connection cannot guarantee the stability of the splicing. Manual assistance also increases on-site risks, and the supporting components between the two guide wall plates are difficult to install and disassemble, increasing construction costs.

[0013] Therefore, there is a need for an assembled wall guide device for underground continuous wall construction to solve the problems of not being able to quickly splice and install, not being able to quickly dismantle during disassembly, and low construction efficiency. Summary of the invention

[0047] like Figure 1-Figure 10 As shown, an assembled wall guide device for underground continuous wall construction comprises two wall guide plates 1, which are symmetrically arranged, wherein a telescopic component 2 is detachably and rotatably arranged on one side of one wall guide plate 1 close to the other wall guide plate 1, a top plate 5 is arranged on the other end of the telescopic component 2, a placement plate 4 is arranged on the outer side of the top plate 5, a bottom plate 3 is detachably installed on the other side of the placement plate 4, top grooves 6 are respectively provided on the tops of the two wall guide plates 1, vertical rods 7 are penetrated and slidably connected to the bottoms of the two top grooves 6, a lifting ear 8 is fixed on the top of each vertical rod 7, a link rod 9 is rotatably installed on one side of the two vertical rods 7, a push rod 10 is rotatably connected to the other side of the link rod 9, a connecting square plate 11 is fixed to the other end of the push rod 10, a limiting plate 12 is fixed to the other end of the connecting square plate 11, a limiting groove 14 is provided on one side of the two wall guide plates 1, and the limiting plates 12 and limiting grooves 14 of two adjacent wall guide devices are clamped with each other.

[0048] In this embodiment, the telescopic assembly 2 is fixed to one side of one of the guide wall plates 1 by means of bolts and connecting components, and the telescopic assembly 2 can be disassembled by removing the screws.

[0049] The two guide wall plates 1 are each provided with a first square groove 15, a second square groove 16, and a third square groove 17, and the first square groove 15 is located at the bottom of the top groove 6, the second square groove 16 is located at the bottom of the first square groove 15, and the third square groove 17 is located at the bottom of the second square groove 16, the top groove 6, the first square groove 15, the second square groove 16 and the third square groove 17 are located in the same vertical direction, and the vertical rod 7 passes through the inner sides of the first square groove 15, the second square groove 16 and the third square groove 17.

[0050] Three connecting rods 9 are provided, and the three connecting rods 9 are respectively located on the inner sides of the first square groove 15, the second square groove 16, and the third square groove 17. A circular groove 20 is opened on the side of each of the first square groove 15, the second square groove 16, and the third square groove 17 close to the push rod 10, and a limiting circular plate 21 is fixed to the inner side of each circular groove 20. The inner side of each limiting circular plate 21 is slidably connected with the push rod 10, and a spring is fixed to the side of each limiting circular plate 21 close to the connecting square plate 11, and the other end of each spring is connected to the side of the connecting square plate 11 close to the limiting circular plate 21. The outer shape of each connecting square plate 11 is set to be a rectangular parallelepiped.

[0051] A top cover 18 is rotatably installed on the top of each top groove 6, a limiting frame 22 is welded to the inner wall of each top groove 6, and the limiting frame 22 is located at the bottom of the top cover 18. A hollow frame 701 is welded to the outer side of one end of each vertical rod 7 located at the top groove 6, and the hollow frame 701 is located at the bottom of the limiting frame 22.

[0052] In this embodiment, the worker uses a magnet to open the top cover 18 of the right guide wall plate 1, then hooks the lifting hook of the lifting equipment with the lifting ear 8, and then places the right guide wall plate 1 inside the trench, and fills the gap between the guide wall plate 1 and the trench with materials (such as soil, gravel, etc., selected according to the construction site, and will not be repeated here), so that the inner side of the right guide wall plate 1 fits with the inner wall of one side of the trench and the top of the ground, and at the same time ensures that the top of the right guide wall plate 1 is level; then the worker uses a magnet to open the left guide wall plate 1, and then hook the lifting hook of the lifting equipment with the lifting ear 8, and then place the left guide wall plate 1 inside the trench, and fill the gap formed by the guide wall plate 1 and the trench with materials (such as soil, gravel, etc., selected according to the construction site, and will not be repeated here), so that the inner side of the left guide wall plate 1 fits with the inner wall of one side of the trench and the top of the ground, and at the same time, the top of the left guide wall plate 1 is guaranteed to be horizontal, and at the same time, the tops of the two guide wall plates 1 are in the same horizontal plane, and the two guide wall plates 1 are fixed, thereby providing positioning and support for subsequent splicing;

[0053] In this embodiment, if Figure 1 As shown, the staff can drill holes on the top and side walls of the two guide wall panels 1, and insert several steel bars into the ground from the inside of the holes, thereby increasing the grip of the two guide wall panels 1. Bolt parts are provided at the tail of the steel bars, which can be threadedly connected to the guide wall panels 1. After the steel bars enter the soil, the bolt parts at their tails are fixed, which improves the strength of the top and sides and can also prevent side wall collapse.

[0054] When splicing, the staff uses the magnet to open the cover 19 of the right guide wall plate 1. When lifting the two guide wall plates 1, the lifting ear 8 drives the vertical rod 7 to move along the first square groove 15, the second square groove 16, and the third square groove 17 toward the top of the guide wall. The vertical rod 7 drives the hollow frame 701 to move until the top of the hollow frame 701 and the bottom of the limit frame 22 are in contact. In the process, the vertical rod 7 drives the link rod 9 to rotate with one end of the push rod 10 as the center of the circle. The link rod 9 pushes the push rod 10 to move toward the side close to the limit plate 12. The connecting square plate 11 is pushed by the push rod 10 to stretch the spring, and the connecting square plate 11 pushes the limit plate 12 to move to the side away from the guide wall plate 1. When the top of the hollow frame 701 and the bottom of the limit frame 22 are in contact, the link rod 9 is horizontal, and then the crane drives the guide wall plate 1 to move to the top of the fixed guide wall plate 1, and makes the limit plate 12 of the guide wall plate 1 to be fixed and the limit groove 14 of the fixed guide wall plate 1 in the same vertical direction, and then the guide wall plate 1 to be fixed is placed inside the trench, and the guide wall plate 1 to be fixed is Under the guidance of the limiting groove 14 of the fixed guide wall plate 1, it falls to the inside of the excavated groove, and while falling, the guide wall plate 1 to be fixed and the fixed guide wall plate 1 are spliced ​​together. When the bottom of the guide wall plate 1 to be fixed contacts the bottom of the excavated groove, the hook continues to fall, and the spring inside the circular groove 20 of the guide wall plate 1 to be fixed pulls the connecting square plate 11 to return to its original position. The connecting square plate 11 drives the vertical rod 7 and the hollow frame 701 to return to their original position through the push rod 10 and the connecting rod 9. The connecting plate of the guide wall plate 1 to be fixed drives the While the limit plate 12 of the guide wall plate 1 is restored to its original position, the fixed guide wall plate 1 is completely fixed to the guide wall plate 1 to be fixed, thereby completing the splicing. Then the staff restores all the covers 19 and the top cover 18 to their original positions, and seals the tops of all the guide wall plates 1, so as to assemble them using the lifting equipment and the device itself. Manual work only needs to assist the limit plate 12 to enter the inner side of the limit groove 14, which not only reduces the construction process and time, but also greatly reduces the manpower consumption caused by manual alignment of the guide wall plates 1.

[0055] When welding, the staff first prepares the surface of the guide plate 1, prepares welding rods and wires, processes and fixes the guide plate 1, then uses an electric welder to perform positioning welding to fix the position of the guide plate 1, and then performs formal welding. Finally, after welding, the weld surface is cleaned to complete the welding and fixing of the guide plate 1. After welding and fixing, the telescopic assembly 2, the bottom plate 3, the placement plate 4 and the top plate 5 need to be disassembled to avoid affecting subsequent construction operations. Example 2

[0056] On the basis of the first embodiment, the telescopic assembly 2 is configured to drive the top plate 5 to move. The telescopic assembly 2 is provided with two groups, which include pads 201, and the two pads 201 are respectively fixed to the sides close to the two guide wall plates 1, and the heights of the two pads 201 are different, and the bottom of one side of each pad 201 that fits the guide wall plate 1 is arc-shaped;

[0057] In this embodiment, the arc-shaped setting of the backing plate 201 limits the rotation direction of the backing plate 201;

[0058] A fixed column 202 is fixed on one side of each pad 201 away from the guide wall plate 1. A rotating rod 203 is installed on the outer side of the fixed column 202 through a bearing. A threaded rod 204 is fixed on the inner side of the rotating rod 203. The threaded rod 204 is hollow in design. A threaded column 205 is installed on the inner side of the threaded rod 204 through threads.

[0059] The two top plates 5 are respectively located at one end of the two threaded rods 204 located outside the rotating rod 203 .

[0060] The two bottom plates 3 are detachably rotatably installed on one side of a guide wall plate 1 close to the other guide wall plate 1, and the two bottom plates 3 are respectively located on the same horizontal plane with the two pads 201. The top of one side of the bottom plate 3 where the two wall guide plates 1 are in contact is arc-shaped, and the top plate 5 is slidably engaged with the inner side of the placement plate 4.

[0061] In this embodiment, the two bottom plates 3 are fixed to one side of another guide wall plate 1 by means of bolts and connecting components, and the two bottom plates 3 can be disassembled by removing the screws. The arc-shaped setting of the bottom plate 3 limits the rotation direction of the pad 201, and the staff drives the rotating rod 203 to reverse ninety degrees by hand, and the rotating rod 203 drives the top plate 5 to reverse ninety degrees through the threaded rod 204 and the threaded column 205, and then drives the bottom plate 3 and the placement plate 4 to rotate and reverse ninety degrees by hand, so that the bottom of the top plate 5 and the bottom wall of the placement plate 4 are in the same horizontal plane, and then limit the top plate 5 with one hand, and turn the rotating rod 203 with the other hand. The rotating rod 203 pushes the rotating rod 203 to move to the side close to the placement plate 4 through the threaded rod 204. When the right side of the top plate 5 enters the placement plate 4, the top plate 5 is released, and the rotating rod 203 is continued to be rotated. The top plate 5 continues to move along the inner side of the placement plate 4, and then squeezes the guide wall plate 1 connected to the bottom plate 3 through the placement plate 4 and the bottom plate 3, thereby providing lateral support for the two guide wall plates 1, and then the staff uses the same steps to drive another top plate 5 to squeeze the placement plate 4 through another telescopic component 2, and also provides lateral support for the two guide wall plates 1 (such as Figure 1 and Figure 2 As shown), the installation of the support rod by manpower is avoided, and there is no need to manually fix the support rod on the inner side of the two guide wall panels 1 for support, thereby reducing manpower consumption. Example 3

[0062] When recycling this guide wall plate 1, it is necessary to disassemble the telescopic component 2, the bottom plate 3, the placement plate 4 and the top plate 5. The staff uses tools to remove the screws that fix the bottom plate 3 and the pad 201, and then moves the telescopic component 2, the bottom plate 3, the placement plate 4 and the top plate 5 out from the inside of the two guide wall plates 1, and then uses the same steps to remove the other telescopic components 2, the bottom plate 3, the placement plate 4 and the top plate 5.

[0063] Before recycling this guide wall plate 1, first determine the cutting position (the seam between the two guide wall plates 1), check the status of the cutting machine, then install a suitable cutting blade, turn on the power of the cutting machine and adjust the cutting parameters, align the cutting machine with the cutting position, and push the cutting blade steadily and evenly to perform the cutting operation. After the cutting is completed, turn off the power of the cutting machine and clean the cutting area.

[0064] When recycling the guide wall plate 1, the staff first lifts it up as shown in the figure. Fig.10 As shown in the figure, the guide wall plate 1 on the left side, during the lifting process, the lifting ear 8 drives the vertical rod 7 to move along the inner sides of the first square groove 15, the second square groove 16, and the third square groove 17 toward the top of the guide wall. In the process of the vertical rod 7 driving the hollow frame 701 to move until the top of the hollow frame 701 and the bottom of the limit frame 22 are in contact, the vertical rod 7 drives the connecting rod 9 to rotate with one end of the push rod 10 as the center of the circle, and the connecting rod 9 pushes the push rod 10 to move toward the side close to the limit plate 12. The push rod 10 pushes the connecting square plate 11 to stretch the spring, and the connecting square plate 11 pushes the limit plate 12 to move toward the side away from the guide wall plate 1. When the top of the hollow frame 701 and the bottom of the limit frame 22 are in contact, the connecting rod 9 is horizontal and continues to lift. At the same time, the limit plate 12 is detached from the inner side of the limit groove 14. The staff lifts as shown in the figure. Fig.10 As shown in the figure, the guide wall plate 1 on the right side, during the lifting process, the lifting ear 8 drives the vertical rod 7 to move toward the top of the guide wall along the inner sides of the first square groove 15, the second square groove 16, and the third square groove 17. In the process of the vertical rod 7 driving the hollow frame 701 to move until the top of the hollow frame 701 and the bottom of the limiting frame 22 are in contact, the vertical rod 7 drives the connecting rod 9 to rotate with one end of the push rod 10 as the center of the circle, and the connecting rod 9 pushes the push rod 10 to move toward the side close to the limit plate 12. The push rod 10 pushes the connecting square plate 11 to stretch the spring, and the connecting square plate 11 pushes the limit plate 12 to move toward the side away from the guide wall plate 1. When the top of the hollow frame 701 and the bottom of the limiting frame 22 are in contact, the lifting is continued to complete the disassembly.

[0065] In the above embodiment, a method for assembling an assembled wall guide device for underground continuous wall construction comprises the following steps:
