Description
Technical Field
[0001] This application relates to the field of underground wall construction technology, and in particular to a slotted plate structure for guide walls of different widths. Background Technology
[0002] Guide wall construction is a crucial step in ensuring the axial position and trenching quality of the underground wall. The construction accuracy of the guide wall directly affects the accuracy of the underground wall; therefore, when constructing the guide wall, attention must be paid to the clear dimensions inside the guide wall, vertical and horizontal accuracy, and planar position.
[0003] In the fields of water conservancy engineering and building construction, it is sometimes necessary to construct multiple walls of different widths underground to form composite walls, thereby meeting construction requirements. For example, in flood control projects for ship locks, both seepage barriers and reinforced concrete diaphragm walls need to be constructed; moreover, the seepage barrier wall is located below the reinforced concrete diaphragm wall, and its thickness is less than that of the reinforced concrete diaphragm wall. With the continuous advancement of infrastructure construction, the application of composite walls of different widths is increasing, especially in scenarios such as deep foundation pit support and the combination of diaphragm walls and seepage barriers, which places higher demands on construction efficiency, cost control, and environmental protection. To adapt to these needs, construction technology is also constantly improving, gradually forming a variety of construction methods and supporting equipment.
[0004] Guide walls are crucial for ensuring the accurate positioning and trenching quality of diaphragm walls. During construction, guide walls frequently bear static and dynamic loads from the reinforcing cage, concrete pouring guide pipes, drilling rigs, etc., thus requiring careful design and construction before formal diaphragm wall construction can begin. Since the spacing between the two guide walls is strictly designed and constructed according to the width requirements of the diaphragm wall, when constructing composite walls with different widths for upper and lower layers, two separate guide wall constructions are necessary. First, the narrower lower layer guide wall is constructed, and then the wider upper layer guide wall is demolished and reconstructed. This process is time-consuming, costly, and inefficient. Furthermore, before constructing the second guide wall, the trench section from the first guide wall needs to be backfilled. During backfilling, mud must be pumped out and replaced with cohesive soil; otherwise, the trench section is prone to collapse, making trenching of the reinforced concrete diaphragm wall difficult. Additionally, the high filling coefficient of the concrete in the trench section leads to significant material consumption. Moreover, because the trench section was soaked in mud in the early stages, the trench walls are unstable and prone to collapse during guide wall excavation, further increasing construction difficulty. Therefore, how to achieve efficient reuse of guide walls with different widths has become an urgent technical problem to be solved. Utility Model Content
[0005] In order to improve the utilization rate of guide walls, reduce construction costs, and improve construction safety and efficiency when constructing composite walls of different widths, this application provides a slotted plate structure for guide walls of composite walls of different widths.
[0006] The slotted plate structure for guide walls of composite walls of different widths provided in this application adopts the following technical solution:
[0007] A slotted plate structure for guide walls of different widths includes a top plate, a first side plate, and a second side plate. Both the first and second side plates are vertically arranged, with the first and second side plates spaced parallel to each other and capable of being inserted between the two guide walls. The top plate lies flat on the upper side of the first and second side plates and is vertically connected to both the first and second side plates. The top plate has wing-like portions on both sides for support on the upper side of the two guide walls. A slotted hole is formed in the middle of the top plate in the width direction, and the side walls of the slotted hole are flush with the opposite sides of the first and second side plates.
[0008] In implementing this technical solution, a slotted plate structure that meets the dimensional requirements is first designed and fabricated based on the width difference between the two underground walls. For example, when fabricating a combined wall with a 600mm wide cutoff wall at the bottom and a 1000mm wide diaphragm wall at the top, there is no need to construct the guide wall for the cutoff wall first; the guide wall for the 1000mm wide diaphragm wall can be constructed directly. After the guide wall for the 1000mm wide diaphragm wall is completed, the slotted plate structure described in this application is installed inside the guide wall of the 1000mm wide diaphragm wall. The design of the wing section effectively enhances the stability of the slotted plate structure on the guide wall. By guiding the verticality of the trenching machine's grab bucket through the slotted plate structure, the 600mm wide cutoff wall can be constructed. After the 600mm wide cutoff wall is poured, the slotted plate structure is removed, and then the 1000mm wide diaphragm wall is constructed. This slotted plate can be reused; if it deforms or is damaged during construction, it can be repaired or remanufactured.
[0009] The slotted plate structure in this application can be directly lifted away after the slot is formed, allowing for the construction of the next slot. This not only necessitates processing the guide wall only once, but also enables the reuse of the slotted plate structure. This solves the problem of repeated construction of guide walls of different widths, significantly reducing material consumption, improving efficiency, and lowering construction difficulty. Furthermore, it is convenient to construct, provides stable and reliable quality, and has good potential for widespread application.
[0010] Optionally, a top frame is provided at the bottom of the top plate, the top frame including at least 4 longitudinal beams and at least 2 transverse beams; the longitudinal beams and transverse beams together form a rectangular frame structure; the top plate is welded to the top frame, wherein two longitudinal beams are respectively located on both sides of the top plate, two longitudinal beams are respectively located on both sides of the slotted holes on the top plate, and two transverse beams are respectively located at both ends of the top plate.
[0011] By adopting the above technical solutions, the top plate is made lightweight, saving manufacturing costs and reducing construction difficulty. At the same time, the overall structural strength of the top plate is improved, enabling it to better withstand the impact force during trenching machine grab bucket construction, thus ensuring the stability of the slot plate structure. Furthermore, the rectangular frame structure design rationally distributes stress points, further improving structural reliability. In addition, the welding connection between the top plate and the top frame ensures a strong bond between the two, extending the service life of the slot plate.
[0012] Optionally, several reinforcing beams are also provided at intervals between two adjacent longitudinal beams on the same side of the slotted holes on the top plate to strengthen the connection between the longitudinal beams.
[0013] By adopting the above technical solutions, the overall structural strength of the top frame and the top plate has been further enhanced.
[0014] Optionally, a first side frame is provided on the side of the first side plate away from the second side plate; the first side frame includes a plurality of spaced first vertical beams, and the first side plate is welded to the first side frame; a second side frame is provided on the side of the second side plate away from the first side plate, and the second side plate is welded to the second side frame; the second side frame includes a plurality of spaced second vertical beams, and the upper ends of all the first vertical beams and the upper ends of all the second vertical beams are welded to the bottom of the corresponding longitudinal beam above them.
[0015] By adopting the above technical solution, the first and second side plates are supported by the first and second side frames, respectively, enhancing the overall structural strength and stability of the slot plate and ensuring effective resistance to external forces during construction. Simultaneously, the first and second vertical beams are welded to the bottom of the longitudinal beams of the top frame, further improving the rigidity and connection reliability of the slot plate structure and preventing deformation or damage caused by uneven stress, thereby ensuring the accuracy and safety of the slotting machine's grab bucket during vertical alignment.
[0016] Optionally, a downwardly inclined first guide plate is welded to the lower end of all the first vertical beams, and a downwardly inclined second guide plate is welded to the lower end of all the second vertical beams; the first guide plate and the second guide plate cause the lower sides of the first side plate and the second side plate to form a downwardly flared opening.
[0017] By adopting the above technical solution, the first guide plate and the second guide plate make the lower sides of the first side plate and the second side plate form a downward-facing flared mouth, which can effectively prevent the grab bucket of the grooving machine from scraping the bottom of the first side plate and the second side plate during the lifting process, thereby preventing the grooving plate structure from shifting or being damaged, and ensuring the stability and safety of the construction process.
[0018] Optionally, a first angle steel is provided between any two adjacent first vertical beams and is welded and fixed to the top plate and the first side plate respectively; a second angle steel is provided between any two adjacent second vertical beams and is welded and fixed to the top plate and the second side plate respectively.
[0019] By adopting the above technical solution, the installation of the first and second angle steels enhances the overall strength of the slot plate structure, making the connection between the first and second side plates and the top plate more stable. This effectively prevents structural deformation caused by uneven stress during the operation of the slotting machine's grab bucket. Simultaneously, this reinforcement method increases the service life of the slot plate, ensuring it maintains good working performance even after repeated use, further improving construction efficiency and reducing material waste.
[0020] Optionally, a number of lifting lugs are distributed at both ends of the top plate, and the lifting lugs have through holes for threading steel wire ropes or steel bars.
[0021] By adopting the above technical solution, the perforations on the lifting lugs allow for the threading of wire ropes or reinforcing bars, thus facilitating the overall hoisting and disassembly of the slotted plate structure. This design significantly improves the ease of operation of the slotted plate structure during construction, reduces manual intervention, and enhances construction efficiency.
[0022] Optionally, the top plate, the first side plate, and the second side plate are all made of stainless steel, and the top frame, the first side frame, and the second side frame are all made of channel steel, I-beams, or / and angle steel.
[0023] By adopting the above technical solution, the overall strength and durability of the card slot plate structure can be effectively improved, ensuring its stable performance in complex construction environments. The top plate, first side plate, and second side plate, made of stainless steel, possess excellent corrosion resistance and wear resistance, extending the service life of the card slot plate while facilitating cleaning and maintenance. The top frame, first side frame, and second side frame are made of channel steel, I-beams, and / or angle steel, ensuring not only structural rigidity and stability but also optimizing material utilization efficiency and reducing production costs. This preferred solution allows the card slot plate to maintain good performance during repeated use, further improving construction efficiency and reducing material consumption.
[0024] Optionally, the thickness of the top plate, the first guide plate, and the second guide plate is 15mm to 20mm; the thickness of the first side plate and the second side plate is 8mm to 12mm.
[0025] By adopting the above technical solutions, the structure can be ensured to have sufficient strength and rigidity, effectively avoiding deformation or damage caused by uneven stress during the construction of the trenching machine's grab bucket, while also ensuring the durability and stability of the slot plate. The above thickness parameters are designed to meet the required strength when inserted between the two guide walls, while further optimizing material usage, reducing overall weight, facilitating hoisting and reuse, thereby improving construction efficiency and reducing material consumption.

[0029] 3. The slot plate structure in this application is reusable, which reduces material consumption, lowers construction difficulty, avoids the impact of mud soaking on the stability of the slot wall during backfilling and excavation, improves safety, and achieves energy-saving and environmental protection effects.

Two parallel and spaced longitudinal beams 41 are provided on each side of the slotted hole 12 on the top plate 10. The top plate 10 is welded to the top frame 40, wherein the two longitudinal beams 41 are respectively located on both sides of the top plate 10, the two longitudinal beams 41 are respectively located on both sides of the slotted hole 12 on the top plate 10, and the two transverse beams 42 are respectively located at both ends of the top plate 10. Several reinforcing beams 43 are also provided at intervals between two adjacent longitudinal beams 41 on the same side of the slotted holes 12 on the top plate 10 to strengthen the connection between the longitudinal beams 41. In this embodiment, there are four reinforcing beams 43 between two adjacent longitudinal beams 41.
[0049] Reference Figure 3 As shown in the embodiment of this application, a plurality of lifting lugs 70 are distributed at both ends of the top plate 10, and the lifting lugs 70 have through holes 71 for threading steel wire ropes or steel bars. The through holes 71 on the lifting lugs 70 facilitate the threading of steel wire ropes or steel bars, thereby making it convenient for the overall hoisting and disassembly of the slotted plate structure. This design significantly improves the ease of operation of the slotted plate structure during construction, reduces manual intervention, and improves construction efficiency.
[0050] Reference Figure 3 , Figure 4 and Figure 5 As shown, the first side plate 20 and the second side plate 30 are both vertically arranged, the first side plate 20 and the second side plate 30 are parallel and spaced apart, and the first side plate 20 and the second side plate 30 can be inserted between the two side guide walls; the top plate 10 is laid flat on the upper side of the first side plate 20 and the second side plate 30, and the top plate 10 is vertically connected to the first side plate 20 and the second side plate 30; the top plate 10 has wing portions 11 on both sides for supporting on the upper side of the two side guide walls; the two side walls of the slotted hole 12 are flush with the opposite sides of the first side plate 20 and the second side plate 30.
[0051] Furthermore, a first side frame 50 is provided on the side of the first side plate 20 away from the second side plate 30; the first side frame 50 includes several spaced-apart first vertical beams 51, and the first side plate 20 is welded to the first side frame 50; a second side frame 60 is provided on the side of the second side plate 30 away from the first side plate 20, and the second side plate 30 is welded to the second side frame 60; the second side frame 60 includes several spaced-apart second vertical beams 61, and the upper ends of all first vertical beams 51 and all second vertical beams 61 are welded to the bottom of the corresponding longitudinal beams 41 above them. The first side plate 20 and the second side plate 30 are supported by the first side frame 50 and the second side frame 60 respectively, which enhances the overall structural strength and stability of the slot plate and ensures that it can effectively resist the action of external forces during construction. Meanwhile, the first vertical beam 51 and the second vertical beam 61 are welded to the bottom of the longitudinal beam 41 of the top frame 40, which further improves the rigidity and connection reliability of the slot plate structure, avoids deformation or damage caused by uneven stress, and thus ensures the accuracy and safety of the slotting machine grab bucket in the vertical alignment process.
[0052] Reference Figure 4 and Figure 5 As shown, all the lower ends of the first vertical beams 51 are welded with downward-sloping first guide plates 52, and all the lower ends of the second vertical beams 61 are welded with downward-sloping second guide plates 62. The first guide plates 52 and the second guide plates 62 cause the lower sides of the first side plate 20 and the second side plate 30 to form downward-facing flared openings. The first guide plates 52 and the second guide plates 62 cause the lower sides of the first side plate 20 and the second side plate 30 to form downward-facing flared openings, which can effectively prevent the grab bucket of the trenching machine from scraping the bottom of the first side plate 20 and the second side plate 30 during the lifting process, thereby preventing displacement or damage to the trenching plate structure and ensuring the stability and safety of the construction process.
[0053] Reference Figure 2 and Figure 5 As shown, in this embodiment, a first angle steel 53, welded and fixed to the top plate 10 and the first side plate 20 respectively, is provided between any two adjacent first vertical beams 51; a second angle steel 63, welded and fixed to the top plate 10 and the second side plate 30 respectively, is provided between any two adjacent second vertical beams 61. The provision of the first angle steel 53 and the second angle steel 63 enhances the overall strength of the slot plate structure, making the connection between the first side plate 20 and the second side plate 30 and the top plate 10 more stable, thereby effectively preventing structural deformation caused by uneven stress during the operation of the slotting machine grab bucket. At the same time, this reinforcement method improves the service life of the slot plate, ensuring that it can maintain good working performance even after repeated use, further improving construction efficiency and reducing material consumption.
[0054] In this embodiment, the top plate 10, the first side plate 20, and the second side plate 30 are all made of stainless steel plate, and the top frame 40, the first side frame 50, and the second side frame 60 are all made of channel steel, I-beam steel, and / or angle steel. The thickness of the top plate 10, the first guide plate 52, and the second guide plate 62 is 15mm to 20mm; the thickness of the top plate 10, the first guide plate 52, and the second guide plate 62 can be 16mm, 18mm, or 20mm; the thickness of the first side plate 20 and the second side plate 30 is 8mm to 12mm; the thickness of the first side plate 20 and the second side plate 30 can be 8mm, 9mm, or 10mm.
[0055] The top plate 10, first side plate 20, and second side plate 30, made of stainless steel, possess excellent corrosion resistance and wear resistance, extending the service life of the slot plate while facilitating cleaning and maintenance. The top frame 40, first side frame 50, and second side frame 60 are constructed from channel steel, I-beams, and / or angle steel, ensuring structural rigidity and stability while optimizing material utilization and reducing production costs. This preferred design allows the slot plate to maintain good performance during repeated use, further improving construction efficiency and reducing material consumption. The aforementioned thickness parameters, while meeting the required strength for insertion between the two guide walls, further optimize material usage, reduce overall weight, and facilitate hoisting and reuse, thereby improving construction efficiency and reducing material consumption.
[0056] The implementation principle is as follows: When implementing the technical solution in this application, a slotted plate structure that meets the dimensional requirements is first designed and processed according to the width difference between the two underground walls. For example, when processing a combined wall with a 600mm wide seepage barrier and a 1000mm wide diaphragm wall, there is no need to construct the guide wall for the seepage barrier first; the guide wall for the 1000mm wide diaphragm wall can be constructed directly. After the guide wall for the 1000mm wide diaphragm wall is completed, the slotted plate structure of this application is installed inside the guide wall of the 1000mm wide diaphragm wall. The design of the wing part 11 effectively enhances the stability of the slotted plate structure on the guide wall. By guiding the verticality of the grab bucket of the trenching machine through the slotted plate structure, the 600mm wide seepage barrier can be constructed. After the 600mm wide seepage barrier is poured, the slotted plate structure is removed, and then the 1000mm wide diaphragm wall is constructed. This slotted plate can be reused; if deformation or damage occurs during construction, it can be repaired or remanufactured.
[0057] The slotted plate structure in this application can be directly lifted away after the slot is formed, allowing for the construction of the next slot. This not only necessitates processing the guide wall only once, but also enables the reuse of the slotted plate structure. This solves the problem of repeated construction of guide walls of different widths, significantly reducing material consumption, improving efficiency, and lowering construction difficulty. Furthermore, it is convenient to construct, provides stable and reliable quality, and has good potential for widespread application.
[0058] This application achieves lightweight design of the slot plate structure, saving manufacturing costs and reducing construction difficulty. Simultaneously, it enhances the overall structural strength, enabling the top plate 10, first side plate 20, and second side plate 30 to better withstand the impact forces during slotting machine grab bucket construction, thus ensuring the stability of the slot plate structure. Furthermore, the rectangular frame structure design rationally distributes stress points, further improving structural reliability. In addition, the welding connection between the top plate 10 and the top frame 40 ensures a strong bond between them, extending the service life of the slot plate.
[0059] Example 2
[0060] Reference Figure 6 and Figure 7As shown, this embodiment is largely the same as Embodiment 1, except that in this embodiment, two sets of adjustment components 80 for adjusting the distance between the first side plate 20 and the second side plate 30 are provided between the first side frame 50 and the second side frame 60. The first side frame 50 and the second side frame 60 can be set as rectangular frames. The two sets of adjustment components 80 are respectively set at both ends of the first side frame 50 and the second side frame 60. The adjustment component 80 includes a first adjustment plate 81 and a second adjustment plate 82 arranged in parallel and spaced opposite to each other. The first adjustment plate 81 is fixedly connected to the end of the first side plate 20, and the second adjustment plate 82 is fixedly connected to the end of the second side plate 30. The first adjustment plate 81 and the second adjustment plate 82 are connected by a scissor fork connecting rod 83. The fork link 83 includes a first link 831 and a second link 832, which are hinged together at their middle parts. The side of the first adjusting plate 81 has a first strip hole 811, the length of which is along the height of the first adjusting plate 81. The side of the second adjusting plate 82 has a second strip hole 821, the length of which is along the height of the second adjusting plate 82. One end of the first link 831 is hinged to the side of the first adjusting plate 81, and the other end is slidably connected to the second strip hole 821 on the side of the second adjusting plate 82. One end of the second link 832 is hinged to the side of the second adjusting plate 82, and the other end is slidably connected to the first strip hole 811 on the side of the first adjusting plate 81. Furthermore, the scissor fork linkage 83 can be configured as two sets, symmetrically arranged at both ends of the first adjusting plate 81 and the second adjusting plate 82. One end of the first link 831 in the two sets of scissor fork linkage 83 is connected to the first adjusting plate 81 through the first hinge rod 84, and is hinged to the first adjusting plate 81 through the first hinge rod 84. The other end of the first link 831 in the two sets of scissor fork linkage 83 is connected to the second hinge rod 85, and is slidably inserted into the second slot 821 of the second adjusting plate 82 through the second hinge rod 85. One end of the second link 832 in the two sets of scissor fork linkage 83 is connected to the second adjusting plate 82 through the third hinge rod 86, and is hinged to the second adjusting plate 82 through the third hinge rod 86. The other end of the second link 832 in the two sets of scissor fork linkage 83 is connected to the first hinge rod 87, and is slidably inserted into the first slot 811 of the first adjusting plate 81 through the fourth hinge rod 87. A vertical adjusting screw 88 is screwed onto the first adjusting plate 81, and a threaded nut sleeve 89 is fixedly connected to the fourth hinge rod 87. The lower end of the adjusting screw 88 is screwed into the threaded nut sleeve 89.
[0061] Correspondingly, the upper side of the first side plate 20 has a bent first horizontal portion 21, and the upper side of the second side plate 30 has a bent second horizontal portion 31. The first horizontal portion 21 and the second horizontal portion 31 extend in opposite directions. The first horizontal portion 21 and the second horizontal portion 31 are used to fill the horizontal space formed after the first side plate 20 and the second side plate 30 move relative to each other. Alternatively, in this embodiment, the top plate 10 can adopt a two-half structure. The two half plates are spliced together to form a complete top plate 10. The opposite side of the two half plates is grooved. After the two half plates are spliced together, the two grooves are combined to form a slot 12. The two half plates can be slidably connected to the top frame 40 and can be detachably fastened by bolts. The side of the two half plates that meet can partially overlap and be stacked together to adjust the width of the slot 12.
[0062] The implementation principle is as follows: By rotating the adjusting screw 88, the threaded sleeve 89 and the fourth hinge rod 87 can be moved up and down, thereby causing the scissor fork connecting rod 83 to swing, thus adjusting the distance between the first adjusting plate 81 and the second adjusting plate 82, and between the first side plate 20 and the second side plate 30. This can overcome the machining errors or assembly errors of the parts and improve the accuracy and reliability of the slot plate structure. At the same time, this structure can also be used to adjust the distance between the first side plate 20 and the second side plate 30 to adapt to the construction of combined walls with different width differences, thereby improving the versatility of the slot plate structure.
[0063] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
