Description

Technical Field

[0001] This application relates to the technical field of diaphragm wall reinforcement cage construction, and particularly relates to an installation guiding device for a diaphragm wall reinforcement cage. Background Art

[0002] As a widely used underground support structure, the diaphragm wall has the characteristics of strong support capacity, good integrity, strong impermeability, and can be used as part of the main structure. Its main principle is to excavate the trench segments in stages along the periphery of the foundation pit, lower the reinforcement cage, and pour concrete to form a continuous underground wall, which can resist the external soil pressure during the foundation pit construction process and ensure the stability of the foundation pit. The installation of the diaphragm wall reinforcement cage has certain accuracy requirements for both the plane position and verticality of the reinforcement cage.

[0003] In the traditional hoisting process of the reinforcement cage, a guiding device is often set at the top of the trench segment, and the reinforcement cage is vertically lowered by the action of its own gravity, thereby controlling the installation accuracy of the reinforcement cage in the foundation pit.

[0004] For the diaphragm wall with a rigid joint, the rigid joint of the先期槽段 (should be "preceding trench segment") and the reinforcement cage of the subsequent trench segment adopt lap joint, and the installation accuracy requirements for the reinforcement cage of the subsequent trench segment are relatively high. When the depth of the diaphragm wall trench segment is relatively large, the reinforcement cage shows relatively large flexibility, and it is difficult to meet the installation accuracy requirements by only setting a guiding device at the top opening for restraint. Summary of the Invention

[0005] The embodiments of this application provide an installation guiding device for a diaphragm wall reinforcement cage to solve the problem in the related technology that the current installation guiding mechanism for the diaphragm wall reinforcement cage cannot ensure the positioning accuracy during the installation of the reinforcement cage and affects the installation accuracy.

[0006] The embodiments of this application provide an installation guiding device for a diaphragm wall reinforcement cage, including:

[0007] A guiding device body, the guiding device body includes two relatively arranged and detachably connected "L" - shaped guiding plates, and a "匚" - shaped guiding structure is formed between the two "L" - shaped guiding plates;

[0008] An adjusting device, the adjusting device is connected between the two "L" - shaped guiding plates and is used to adjust the distance between the two "L" - shaped guiding plates.

[0009] In some embodiments, the adjusting device includes a screw rod connected between the two "L" - shaped guiding plates and nuts threadedly connected to both ends of the screw rod.

[0010] It should be noted that there is an unclear expression "先期槽段" in the original text, which is tentatively translated as "preceding trench segment" here. If there is a more accurate term, it can be adjusted accordingly.In some embodiments, the "L"-shaped guide plate includes a connecting section for connecting the steel box of the constructed groove section and a guiding section connected to the connecting section, and an adjusting mechanism for adjusting the overall length of the "L"-shaped guide plate is provided between the connecting section and the guiding section.

[0011] In some embodiments, the adjusting mechanism includes nuts fixed inside the connecting section and the guiding section, and a screw rod threadedly connected between the two nuts.

[0012] In some embodiments, a connecting member for connecting the steel box is provided on the connecting section.

[0013] In some embodiments, the connecting member includes a plurality of rivets fixed to the steel box in the height direction and a connecting plate fixed to the connecting section and inserted and fixed to the rivets.

[0014] In some embodiments, a lifting lug is provided at the top of the guiding device body. <00​​​​​​​​​​​​​​​​In actual use, two relatively arranged and mutually detachable "L"-shaped guide plates are the main body parts of the device. They are arranged in a relative manner and connected together by a detachable connection method. When they are connected together, a "C"-shaped guiding structure will be formed between them. This "C"-shaped guiding structure provides precise guidance for the lowering of the steel reinforcement cage. During the lowering process of the steel reinforcement cage, its two sides will slide along this guiding structure, so as to ensure that the steel reinforcement cage can be accurately installed into the foundation pit according to the predetermined path and position. In use, the guide device body is first connected to the steel box of the先期槽段 (preliminary slot section) as the installation reference for the steel reinforcement cage of the subsequent slot section. When the steel reinforcement cage of the subsequent slot section is lowered, it is lowered along the outer contour of the guide device, so as to ensure high-precision installation within the full length of the steel reinforcement cage. The adjusting device is connected between the two "L"-shaped guide plates, and its main function is to adjust the distance between the two "L"-shaped guide plates to adapt to steel reinforcement cages of different sizes. The guide device body and the adjusting device together constitute a complete installation guiding device. The guide device body provides precise guidance for the steel reinforcement cage, while the adjusting device ensures that this guidance can adapt to steel reinforcement cages of different sizes. During the installation process, first adjust the adjusting device according to the size of the steel reinforcement cage to make the distance between the two "L"-shaped guide plates match the steel reinforcement cage. Then, install the entire guide device at the predetermined position on the edge of the foundation pit. Finally, lower the steel reinforcement cage along the guiding structure until it reaches the predetermined installation position. This installation guiding device has the advantages of simple structure, convenient operation and strong adaptability. It can not only improve the installation accuracy and efficiency of the steel reinforcement cage, but also reduce the errors and difficulties during the installation process. It can solve the guiding and positioning problems during the installation of the steel reinforcement cage and ensure the accuracy of the installation of the diaphragm wall steel reinforcement cage.

[0030] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the scope of protection of the present application

[0031] The embodiments of the present application provide an installation guiding device for a diaphragm wall steel reinforcement cage, which can solve the problem in the related art that the current installation guiding mechanism for the diaphragm wall steel reinforcement cage cannot ensure the positioning accuracy during the installation of the steel reinforcement cage and affects the installation accuracy

[0032] See Figure 1 and Figure 5 As shown in and , the embodiments of the present application provide an installation guiding device for a diaphragm wall steel reinforcement cage, including a guiding device body and an adjusting device 2. The guiding device body includes two relatively arranged and detachably connected "L"-shaped guiding plates 1, and a "匚"-shaped guiding structure is formed between the two "L"-shaped guiding plates 1; the adjusting device 2 is connected between the two "L"-shaped guiding plates 1 and is used to adjust the distance between the two "L"-shaped guiding plates 1

[0033] In actual use, two relatively arranged and mutually detachable "L"-shaped guide plates 1 are the main body parts of the device. They are arranged in a relative manner and connected together by a detachable connection method. When they are connected together, a "U"-shaped guiding structure is formed between them. This "U"-shaped guiding structure provides precise guidance for the lowering of the steel reinforcement cage 7. During the lowering process of the steel reinforcement cage 7, its two sides will slide along this guiding structure, so as to ensure that the steel reinforcement cage 7 can be accurately installed into the foundation pit according to the predetermined path and position. In use, the guiding device body is first connected to the steel box 4 of the先期槽段 (the specific name in Chinese is not clear, it may be a precast slot section steel box). As the installation benchmark for the steel reinforcement cage 7 of the subsequent slot section, when the steel reinforcement cage 7 of the subsequent slot section is lowered, it is lowered along the outer contour of the guiding device, and the high-precision installation within the full length of the steel reinforcement cage 7 can be ensured. The adjusting device 2 is connected between the two "L"-shaped guide plates 1, and its main function is to adjust the distance between the two "L"-shaped guide plates 1 to adapt to steel reinforcement cages 7 of different sizes. The guiding device body and the adjusting device 2 together constitute a complete installation guiding device. The guiding device body provides precise guidance for the steel reinforcement cage 7, while the adjusting device 2 ensures that this guidance can adapt to steel reinforcement cages 7 of different sizes. During the installation process, first adjust the adjusting device 2 according to the size of the steel reinforcement cage 7 to make the distance between the two "L"-shaped guide plates 1 match the steel reinforcement cage 7. Then, install the guiding device as a whole at the predetermined position on the edge of the foundation pit. Finally, lower the steel reinforcement cage 7 along the guiding structure until it reaches the predetermined installation position. This installation guiding device has the advantages of simple structure, convenient operation, and strong adaptability. It can not only improve the installation accuracy and efficiency of the steel reinforcement cage 7, but also reduce the errors and difficulties during the installation process. It can solve the guiding and positioning problems during the installation of the steel reinforcement cage 7 and ensure the accuracy of the installation of the diaphragm wall steel reinforcement cage 7.

[0034] As Figure 6 , when the steel reinforcement cage 7 is lowered along the guiding device until it reaches the predetermined installation position, the guiding device can be flexibly removed without interfering with the subsequent construction.

[0035] In some optional embodiments, as Figures 1 to 4 shown, the adjusting device 2 includes a screw rod connected between the two "L"-shaped guide plates 1, and nuts threadedly connected to both ends of the screw rod. The screw rod is the core component of the adjusting device 2 and is connected between the two "L"-shaped guide plates 1. It is usually a long strip-shaped metal rod with a threaded surface for cooperating with the nuts to achieve the adjustment of the distance. The nuts are components threadedly connected to both ends of the screw rod. They have internal threads matching the threads of the screw rod. By rotating the nuts, they can move along the screw rod, thereby changing the distance between the two "L"-shaped guide plates 1, making the guiding device adapt to steel reinforcement cages 7 of different sizes.

[0036] In some optional embodiments, as Figure 1As shown, the "L"-shaped guide plate 1 includes a connecting section 11 for connecting the steel box 4 of the constructed trench section and a guide section 12 connected to the connecting section 11. An adjustment mechanism 3 for adjusting the overall length of the "L"-shaped guide plate 1 is provided between the connecting section 11 and the guide section 12. The connecting section 11 is the part of the guide plate that connects to the steel box 4 of the constructed trench section, and the guide section 12 is the part of the guide plate used to guide structures such as the reinforcing cage 7 through. Its shape and size are determined according to specific requirements. The main function of the adjustment mechanism 3 is to flexibly adjust the overall length of the "L"-shaped guide plate 1. This allows for adjustments to meet the needs of different construction environments. For example, when changing the distance between the steel box 4 of the initial trench section and the reinforcing cage 7 of the subsequent trench section, the adjustment mechanism 3 can be used to change the distance between the connecting section 11 and the guide section 12, thereby changing the overall length of the "L"-shaped guide plate 1, thus meeting the needs of different construction environments and improving the universal applicability of the device.

[0037] In some alternative embodiments, the adjusting mechanism 3 includes nuts fixed within the connecting section 11 and the guide section 12, and a screw threaded between the two nuts. By rotating the screw, its position between the two nuts can be changed, thereby effectively adjusting the relative distance between the connecting section 11 and the guide section 12, and thus achieving adjustment of the overall length of the guide plate. Because the adjusting mechanism 3 uses a threaded connection, it has excellent stability and reliability. This connection method can withstand large forces and torques, ensuring that the guide plate remains stable after adjustment and will not loosen or shift during construction. The design of the adjusting mechanism 3 is generally very simple and easy to operate. Furthermore, since the nuts and screw are standard parts, they are easy to purchase and replace, reducing maintenance costs.

[0038] In some alternative embodiments, such as Figure 1 and Figure 5 As shown, the connecting section 11 is equipped with a connector 5 for connecting the steel box 4. In actual use, the connector 5 includes multiple rivets 51 fixed to the steel box 4 along the height direction and a connecting plate 52 fixed to the connecting section 11 and inserted into the rivets 51. The connecting section 11 is part of the "L"-shaped guide plate 1 and is used to connect with the steel box 4. The rivets 51 are fixed to the steel box 4 along the height direction, serving as fixing points for the connecting plate 52. The rivets 51 typically have a head and a shank that passes through the steel box 4 and is riveted together to ensure a secure connection. The connecting plate 52 is a plate-like structure designed with holes that match the rivets 51. It is fixed to the connecting section 11 and is fixed to the rivets 51 by insertion, thereby connecting the connecting section 11 to the steel box 4. The main function of the connector 5 is to ensure a secure connection between the "L"-shaped guide plate 1 and the steel box 4. Through the combined use of the rivets 51 and the connecting plate 52, it can withstand greater forces and torques, preventing loosening or displacement during construction.

[0039] In some alternative embodiments, the nut of the adjusting mechanism 3 is fixed to the inner wall of the connecting section 11 and the guide section 12, and an opening is provided at the adjacent ends of the connecting section 11 and the guide section 12 for the screw of the adjusting mechanism 3 to pass through. The adjusting mechanism 3 is used to adjust the relative position between the connecting section 11 and the guide section 12. An opening is provided at the end of the guide section 12 adjacent to the connecting section 11 for the screw of the adjusting mechanism 3 to pass through. This opening allows the screw to move inside the guide section 12 and, by engaging with the nut inside the connecting section 11, achieves connection and relative position adjustment between the two components.

[0040] In some alternative embodiments, such as Figure 2 and Figure 3 As shown, a lifting lug 6 is provided on the top of the guide device body. The main function of the lifting lug 6 is to provide a lifting point, so that the entire guide device can be easily moved and installed by a crane or other lifting equipment.

[0041] In some alternative embodiments, both the connecting section 11 and the guide section 12 have circular or regular polygonal cross-sections. The circular or regular polygonal cross-sections of the connecting section 11 and the guide section 12 not only provide good mechanical properties and stability but also help reduce wind resistance and fluid resistance. Furthermore, the circular or regular polygonal cross-section design is easier to process and manufacture, reducing manufacturing costs. Because the shape design of the connecting section 11 and the guide section 12 has a certain degree of versatility, this guiding device can adapt to various application scenarios and installation conditions. Users can customize and modify it according to actual needs to meet specific construction requirements.

[0042] In some alternative embodiments, multiple guide device bodies are spaced apart along the height of the steel box 4. This spacing between the multiple guide device bodies provides more balanced and stable support for the steel box 4. This distributed support effectively reduces the load on individual guide devices, thereby improving the overall stability of the structure.
