Description

Technical Field

[0001] The present application relates to the technical field of underground continuous walls, and in particular to an assembled underground continuous wall. Background Art

[0002] An underground continuous wall is a foundation project that uses a trenching machine on the ground to excavate a long and narrow deep trench along the peripheral axis of the deep excavation project under the condition of mud wall protection. After the trench is cleared, a steel cage is hung in the trench, and then underwater concrete is poured using the conduit method to form a unit trench section. This process is carried out section by section to build a continuous reinforced concrete wall underground, which serves as a water interception, anti-seepage, load-bearing and water retaining structure.

[0003] At present, the traditional construction method of underground continuous walls mostly adopts the cast-in-place method. However, in order to shorten the construction period and speed up the construction efficiency, the constructors will prefabricate prefabricated wall modules of corresponding sizes and models in the factory according to the on-site construction requirements. After the prefabricated wall modules are transported to the construction site, they are hoisted into deep trenches for assembly to form underground continuous walls, that is, prefabricated underground continuous walls.

[0004] However, in actual applications of existing prefabricated underground continuous walls, the assembly connection between two adjacent prefabricated wall modules is relatively simple, which can easily affect the tightness of the assembly connection between the two adjacent prefabricated wall modules, and further affect the overall stability of the prefabricated underground continuous wall.

[0032] The present application is further described in detail below with reference to the accompanying drawings.

[0033] The present application discloses an assembled underground continuous wall. Figure 1 and Figure 2 , including several prefabricated wall modules 1 that are assembled and connected. The prefabricated wall module 1 has an integrally formed assembly protrusion 2 on one side along the assembly direction, and an assembly groove 3 on the other side, and the shape of the assembly groove 3 is the same as that of the assembly protrusion 2.

[0034] Reference Figure 3 The assembly protrusion 2 and the prefabricated wall module 1 both have a placement hole 20 formed vertically therein. A sealing waterproof strip 21 is fixedly installed within the placement hole 20. The sealing waterproof strip 21 helps prevent water from flowing through the assembly gap between the two assembled prefabricated wall modules 1, thereby improving the waterproof performance of the prefabricated underground continuous wall.

[0035] Reference Figure 1 and Figure 2The prefabricated wall module 1 is provided with a positioning assembly 4, which includes a positioning base plate 41 and a first positioning rod 42. The positioning base plate 41 is fixedly connected to the bottom of one side of the prefabricated wall module 1 along the assembly direction. The positioning base plate 41 is located within the assembly groove 3, and the bottom surface of the positioning base plate 41 is flush with the bottom surface of the prefabricated wall module 1. A positioning bottom groove 6 is defined at the bottom of the prefabricated wall module 1 on the side away from the positioning base plate 41. In this embodiment, multiple first positioning rods 42 are provided, and multiple first positioning rods 42 are vertically fixedly mounted on the top surface of the positioning base plate 41. A plurality of first positioning sockets 7 are vertically defined on the prefabricated wall module 1.

[0036] Reference Figure 1 and Figure 2 The positioning assembly 4 further includes a top positioning plate 43 and a second positioning rod 44. The top positioning plate 43 is fixedly connected to the top of one side of the prefabricated wall module 1 along the assembly direction. The top positioning plate 43 is located above the bottom positioning groove 6, and the top surface of the top positioning plate 43 is flush with the top surface of the prefabricated wall module 1. A top positioning groove 8 is defined in the top of the side of the prefabricated wall module 1 away from the top positioning plate 43. In this embodiment, a plurality of second positioning rods 44 are provided, each of which is vertically fixedly mounted on the bottom surface of the top positioning plate 43. Furthermore, a plurality of second positioning holes 9 are vertically defined in the prefabricated wall module 1.

[0037] Reference Figure 2 and Figure 3 The positioning component 4 also includes an anti-slip convex strip 45, which is integrally formed on the groove wall of the assembling groove 3 and is vertically arranged. An anti-slip groove 10 is opened at a corresponding position on the assembling protrusion 2.

[0038] Reference Figure 1 and Figure 2 When assembling two adjacent prefabricated wall modules 1, the operator inserts the assembly protrusion 2 into the assembly groove 3 from top to bottom, and inserts the anti-slip protrusion 45 into the anti-slip groove 10 accordingly, inserts the first positioning rod 42 into the first positioning hole 7 accordingly, and inserts the second positioning rod 44 into the second positioning hole 9 accordingly, thereby completing the assembly between the two adjacent prefabricated wall modules 1.

[0039] Reference Figure 1 and Figure 2During the assembly process, the anti-slip ribs 45, the mounting base, the first positioning rods 42, the mounting base, and the second positioning rods 44 help to locate the assembly position between the two prefabricated wall modules 1, thereby helping to improve the accuracy of the assembly position between the two adjacent prefabricated wall modules 1. After the assembly is completed, the positioning base 41 and the positioning top plate 43 help to prevent the two assembled prefabricated wall modules 1 from producing relative displacement in the vertical direction, and the anti-slip ribs 45, the first positioning rods 42, and the second positioning rods 44 help to prevent the two assembled prefabricated wall modules 1 from producing relative displacement in the horizontal direction, thereby helping to improve the tightness of the assembly connection between the two adjacent prefabricated wall modules 1, thereby helping to ensure the overall stability of the assembled underground continuous wall.

[0040] Reference Figure 1 The precast wall module 1 and the bottom surface of the positioning base plate 41 are both fixedly mounted with a mounting base 11. A plurality of mounting rods 15 are vertically fixedly mounted on the bottom surface of the mounting base 11. A casting trough 12 is defined along the length of the bottom surface of the mounting base 11. A casting hole 13 and an exhaust hole 14 are vertically penetrated through the precast wall module 1 and communicate with the casting trough 12.

[0041] Reference Figure 1 When assembling two adjacent prefabricated wall modules 1, inserting the mounting rods 15 into the deep grooves helps improve the stability of the mounting base 11 and the prefabricated wall modules 1 during the assembly process, thereby improving the assembly connection between the two adjacent prefabricated wall modules 1. After the multiple prefabricated wall modules 1 are assembled, concrete is injected into the casting trough 12 through the casting holes 13, allowing the air inside the casting trough 12 to be discharged through the exhaust holes 14. After the concrete solidifies, it helps further connect the multiple mounting bases 11 into a whole, thereby further improving the tightness of the assembly connection between the two adjacent prefabricated wall modules 1 and further ensuring the overall stability of the prefabricated underground continuous wall.

[0042] Reference Figure 4 and Figure 5 The prefabricated wall module 1 is provided with a locking assembly 5 comprising a locking plate 51, a stud bolt 52, and a locking nut 53. Mounting grooves 16 are defined on the sidewalls of the prefabricated wall module 1 on both sides of the assembly groove 3. The locking plate 51 is snap-fitted into the mounting grooves 16. A sealing and waterproofing plate 18 is secured to the surface of the locking plate 51 facing the prefabricated wall module 1. Mounting holes 17 are defined in the locking plate 51, the prefabricated wall module 1, and the assembly protrusion 2. Stud bolts 52 are positioned within the mounting holes 17, with both ends of the stud bolts 52 extending out of the mounting holes 17. Locking nuts 53 are threadedly connected to the ends of the stud bolts 52. Sealing gaskets 19 are removably sleeved on both ends of the stud bolts 52, and are located between the locking plate 51 and the locking nut 53.

[0043] Reference Figure 4 and Figure 5 After the two adjacent prefabricated wall modules 1 are assembled, the stud bolts 52 are inserted into the installation through-holes 17, and the locking plates 51 are tightened and fixed by screwing the locking nuts 53. This helps to lock and fix the two prefabricated wall modules 1 assembled together, further improving the tightness of the assembly connection between the two adjacent prefabricated wall modules 1, and further ensuring the overall stability of the prefabricated underground continuous wall. The sealing gasket 19 helps prevent the locking nuts 53 from loosening on the stud bolts 52, thereby helping to improve the locking and fixing effect of the two locking plates 51, and further helping to improve the locking and fixing effect of the two prefabricated wall modules 1 assembled together. In addition, the sealing waterproof plate 18 and the sealing gasket 19 help to seal both ends of the installation through-hole 17, helping to prevent water from flowing through the installation through-hole 17, and further improving the waterproof performance of the prefabricated underground continuous wall.

[0044] The implementation principle of the embodiment of the present application is: when assembling two adjacent prefabricated wall modules 1, the operator inserts the assembling protrusion 2 into the assembling groove 3 from top to bottom, and makes the anti-slip protrusion 45 correspondingly inserted into the anti-slip groove 10, so that the first positioning rod 42 is correspondingly inserted into the first positioning hole 7, and the second positioning rod 44 is correspondingly inserted into the second positioning hole 9, thereby completing the assembly between the two adjacent prefabricated wall modules 1.

[0045] During the assembly process, the anti-slip rib 45, the mounting base, the first positioning rod 42, the mounting base, and the second positioning rod 44 help to locate the assembly position between the two prefabricated wall modules 1, thereby helping to improve the accuracy of the assembly position between the two adjacent prefabricated wall modules 1. After the assembly is completed, the positioning base 41 and the positioning top plate 43 help to prevent the two assembled prefabricated wall modules 1 from producing relative displacement in the vertical direction, and the anti-slip rib 45, the first positioning rod 42, and the second positioning rod 44 help to prevent the two assembled prefabricated wall modules 1 from producing relative displacement in the horizontal direction, thereby helping to improve the tightness of the assembly connection between the two adjacent prefabricated wall modules 1, thereby helping to ensure the overall stability of the assembled underground continuous wall.

[0046] When assembling two adjacent prefabricated wall modules 1, inserting the mounting rod 15 into the deep groove helps to improve the stability of the mounting base 11 and the prefabricated wall module 1 during the assembly process, thereby helping to improve the assembly connection effect between the two adjacent prefabricated wall modules 1.

[0047] After the two adjacent prefabricated wall modules 1 are assembled, the stud bolts 52 are inserted into the mounting through holes 17, and the locking plates 51 are locked and fixed by screwing the locking nuts 53, thereby helping to lock and fix the two prefabricated wall modules 1 assembled together, helping to further improve the tightness of the assembly connection between the two adjacent prefabricated wall modules 1, and further ensuring the overall stability of the prefabricated underground continuous wall.

[0048] After the assembly of multiple prefabricated wall modules 1 is completed, concrete is injected into the casting trough 12 through the casting hole 13, so that the air inside the casting trough 12 is discharged through the exhaust hole 14. After the concrete solidifies, it helps to further connect the multiple mounting bases 11 into a whole, thereby helping to further improve the tightness of the assembly connection between two adjacent prefabricated wall modules 1, and further ensure the overall stability of the prefabricated underground continuous wall.

[0049] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
