Description

Technical Field

[0001] This utility model relates to the field of explosion-proof devices, and in particular to a prefabricated bamboo-wrapped protective wall. Background Technology

[0002] Protective walls are commonly used in hazardous materials production and military combat training to effectively withstand damage to personnel and equipment caused by blast waves and fragments. Existing protective walls are mostly constructed using sandbags or concrete. Sandbag walls are easy to build, but they fail due to rain erosion and sandbag aging, resulting in a short lifespan. Concrete walls have a longer lifespan, but their construction cost is high and the construction period is long, making them unsuitable for rapid field combat training. Furthermore, existing protective walls are all fixed and immovable, failing to adapt to mobile and changeable requirements.

[0003] Patent document CN213927757U discloses a trapezoidal prefabricated explosion-proof wall, which uses wire mesh and geotextile to form a filling space, and then fills the space with sand or other materials to serve as the explosion-proof wall. The wall has the effect of being easy and quick to move. However, the wire mesh itself has no explosion-proof capability, and it relies entirely on the sand and soil, so the explosion-proof effect is relatively weak. Utility Model Content

[0004] To address the aforementioned problems and overcome shortcomings, this utility model proposes a prefabricated bamboo-wrapped protective wall.

[0005] The technical solutions adopted by this utility model are as follows:

[0006] A prefabricated bamboo-wrapped protective wall includes two wall surfaces, with a filling space between the two wall surfaces for filling with sand and soil;

[0007] The wall surface includes an upper mounting plate, a lower mounting plate, a connector, and an arc-shaped bamboo-wound tube. Both the upper and lower mounting plates have mounting grooves. There are multiple bamboo-wound tubes, and both ends of the bamboo-wound tubes are respectively embedded in the mounting grooves of the upper and lower mounting plates. Multiple bamboo-wound tubes are stacked between the upper and lower mounting plates. The connector is used to connect the upper and lower mounting plates to connect the bamboo-wound tubes into a whole.

[0008] The upper mounting plates on the two walls are connected by a connecting plate.

[0009] The bamboo-wound tubing in this application is obtained by cutting bamboo-wound tubing. By fully utilizing the strong explosion-proof characteristics of the arched structure of bamboo-wound tubing, the overall strength is ensured by overlapping bamboo-wound tubing, resulting in no weak points.

[0010] Bamboo-wound pipe, also known as bamboo-wound composite pipe, comprises an inner lining layer, a composite reinforcement layer, and an outer protective layer. It is a flexible material capable of absorbing external forces through deformation, while its curved shape maximizes the bamboo's resistance to deformation. Based on this, this invention, using bamboo-wound pipe sheets as an explosion-proof wall surface, effectively improves explosion resistance.

[0011] The bamboo-wound tubing involved in this application can be obtained by equally cutting existing bamboo-wound tubing. The tubing has the same specifications and model, meeting the requirements for universal design. After the wall is used, it can be quickly disassembled. The bamboo-wound tubing is stacked on top of each other, occupying a small volume, which is convenient for transportation and storage. In addition, in the field environment, the size of individual tubing can be reduced to meet the needs of individual soldier carrying and transportation.

[0012] In practical applications, aramid mesh fabric, ultra-high molecular weight polyethylene mesh fabric, and other bulletproof fibers can be added to the traditional bamboo winding pipe processing technology to reinforce the pipe segments.

[0013] The diameter, chord length, and wall thickness of bamboo-wound pipe segments can all be adjusted according to the protection level. Generally, DN80~DN2000 is preferred, with a chord length of 400 mm~1000 mm and a wall thickness of 10 mm~50 mm.

[0014] In one embodiment of this utility model, the upper mounting plates of the two walls are connected by multiple connecting plates;

[0015] Both the upper and lower mounting plates have a first mounting hole, and the connecting plate has a second mounting hole. The connecting member includes a rod and a nut. Both ends of the rod are threaded. The lower end of the rod passes through the first mounting hole of the lower mounting plate and is fixed to the lower mounting plate by the nut. The upper end of the rod passes through the first mounting hole of the upper mounting plate and the second mounting hole of the connecting plate and is fixed to the upper mounting plate and the connecting plate by the nut.

[0016] This design eliminates the need for dedicated fasteners to connect the mounting plate and connecting plate, shortening installation time. Furthermore, it eliminates the need for drilling holes in the bamboo-wound tubing, reducing damage to the tubing. In practical applications, metal rods with a diameter of 10 mm to 30 mm are preferred.

[0017] In one embodiment of this utility model, both the first mounting hole and the second mounting hole are strip-shaped holes.

[0018] The design of the slotted holes reduces the requirements for assembly precision and increases the overall flexibility.

[0019] In one embodiment of the present invention, the bamboo-wound tube has a concave surface and a convex surface. In two adjacent bamboo-wound tubes, the convex surfaces of the bamboo-wound tubes are opposite to each other, and one side of one bamboo-wound tube is located in the middle of the concave surface of the other bamboo-wound tube.

[0020] This design ensures overall strength and eliminates weak points while fully utilizing the strong explosion-proof capabilities of the bamboo-wound pipe segment arch structure.

[0021] In one embodiment of the present invention, the lower mounting plate has a fixing hole for the ground nail to pass through so as to fix the lower mounting plate to the ground.

[0022] In one embodiment of the present invention, the lower mounting plate has a lug, and the fixing hole is disposed on the lug.

[0023] In one embodiment of this utility model, the mounting groove is U-shaped, with a depth of 50 mm to 200 mm and a width of 80 mm to 200 mm.

[0024] In one embodiment of this utility model, the upper ends of the two walls are inclined towards each other, forming a trapezoidal filling space. This creates a certain slope, ensuring overall stability.

[0025] The beneficial effects of this utility model are: the bamboo-wound tube sheet of this application is obtained by cutting a complete bamboo-wound tube. While making full use of the strong explosion-proof characteristics of the arched structure of the bamboo-wound tube sheet, the overall strength is guaranteed by the overlapping arrangement of the bamboo-wound tube sheets, so that there are no weak parts.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0034] In the description of this application, it should be noted that the terms "inner" and "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of this application is usually placed when in use. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0035] It should also be noted that, in the description of this application, unless otherwise expressly specified or limited, the terms "disposed" and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0036] The present invention will be described in detail below with reference to the accompanying drawings.

[0037] like Figures 1-5 As shown, a prefabricated bamboo-wrapped protective wall includes two wall surfaces 100, with a filling space 200 formed between the two wall surfaces 100 for filling with sand 300.

[0038] The wall 100 includes an upper mounting plate 1, a lower mounting plate 2, a connector 5, and an arc-shaped bamboo-wound tube 4. Both the upper mounting plate 1 and the lower mounting plate 2 have mounting grooves 11. There are multiple bamboo-wound tubes 4. The upper end of the bamboo-wound tube 4 is embedded in the mounting groove 11 of the upper mounting plate 1, and the lower end of the bamboo-wound tube 4 is embedded in the mounting groove 11 of the lower mounting plate 2. Multiple bamboo-wound tubes 4 are stacked between the upper mounting plate 1 and the lower mounting plate 2. The connector 5 is used to connect the upper mounting plate 1 and the lower mounting plate 2.

[0039] The two wall surfaces 100 are connected by a connecting plate 3.

[0040] The bamboo-wound tube 4 of this application is obtained by cutting a complete bamboo-wound tube. By making full use of the strong explosion-proof characteristics of the arched structure of the bamboo-wound tube 4, the overall strength is ensured by the overlapping arrangement of the bamboo-wound tube 4, so that there are no weak parts.

[0041] Bamboo-wound pipe, also known as bamboo-wound composite pipe, comprises an inner lining layer, a composite reinforcement layer, and an outer protective layer. It is a flexible material capable of absorbing external forces through deformation, while its circular shape maximizes the bamboo's resistance to deformation. Based on this, this invention, using bamboo-wound pipe sheets 4 as the explosion-proof wall surface 100, effectively improves explosion resistance.

[0042] like Figure 5 As shown, the bamboo-wound tube segment 4 involved in this application can be obtained by equally cutting existing bamboo-wound tube segments 4. The tube segments have the same specifications and models, meeting the requirements of universal design. Moreover, the wall can be quickly disassembled after use. The bamboo-wound tube segments 4 can be stacked on top of each other, occupying a small volume and facilitating transportation and storage. At the same time, in the field environment, the size of a single tube segment can be reduced to meet the needs of individual soldier carrying and transportation.

[0043] In practical applications, aramid mesh fabric, ultra-high molecular weight polyethylene mesh fabric, and other bulletproof fibers can be added to the traditional bamboo winding pipe processing technology to reinforce the pipe segments.

[0044] The diameter, chord length, and wall thickness of the bamboo-wound pipe segments can all be adjusted according to the protection level. Generally, DN80~DN2000 is preferred, with a chord length of 400 mm~1000 mm and a wall thickness of 10 mm~50 mm.

[0045] like Figure 1 , 2 As shown in Figures 3 and 4, both the upper mounting plate 1 and the lower mounting plate 2 have a first mounting hole 12, and the connecting plate 3 has a second mounting hole 31. The connecting member 5 includes a rod 51 and a nut 52. Both ends of the rod 51 are threaded. The lower end of the rod 51 passes through the first mounting hole 12 of the lower mounting plate 2 and is fixed to the lower mounting plate 2 by the nut 52. The upper end of the rod 51 passes through the first mounting hole 12 of the upper mounting plate 1 and the second mounting hole 31 of the connecting plate 3 and is fixed to the lower mounting plate 2 and the connecting plate 3 by the nut 52.

[0046] This design eliminates the need for dedicated fasteners to connect the upper mounting plate 1 and the connecting plate 3. The connector 5 can connect both the upper mounting plate 1 and the lower mounting plate 2, and also connect the upper mounting plate 1 and the connecting plate 3. Furthermore, it eliminates the need for drilling holes in the bamboo-wound tubular segments 4, reducing damage to the segments. In practical applications, the rod 51 is preferably a metal rod with a diameter of 10mm to 30mm.

[0047] like Figure 3 and 4 As shown, in this embodiment, both the first mounting hole 12 and the second mounting hole 31 are strip-shaped holes. The design of the strip-shaped holes can reduce the assembly precision requirements and increase the overall flexibility.

[0048] like Figure 3As shown, in this embodiment, the bamboo-wound tube 4 has a concave surface 42 and a convex surface 41. In two adjacent bamboo-wound tubes 4, the convex surfaces 41 of the bamboo-wound tubes 4 are opposite to each other, and one side of one bamboo-wound tube 4 is located in the middle of the concave surface 42 of the other bamboo-wound tube 4. This arrangement can fully utilize the strong explosion-proof characteristics of the arched structure of the bamboo-wound tube 4 while ensuring overall strength and eliminating weak points.

[0049] like Figure 1 and 2 As shown, in this embodiment, the lower mounting plate 2 has fixing holes (not shown in the figure), which are used for the ground nails 6 to pass through so that the lower mounting plate 2 is fixed to the ground.

[0050] like Figure 1 and 2 As shown, in this embodiment, the lower mounting plate 2 has a lug 21, and a fixing hole is provided on the lug 21.

[0051] like Figure 1 and 2 As shown, in this embodiment, the mounting groove 11 is U-shaped, with a depth of 50 mm to 200 mm and a width of 80 mm to 200 mm.

[0052] like Figure 1 and 2 As shown, in this embodiment, the upper ends of the two walls 100 are inclined towards each other, forming a trapezoidal structure for the filling space 200. This creates a certain slope, ensuring overall stability.

[0053] This utility model's prefabricated bamboo-wound protective wall utilizes bamboo-wound pipes 4 as the wall surface 100, satisfying the explosion-proof protection function while being easy to transport and convenient for field training. The prefabricated bamboo-wound protective wall of this embodiment, using bamboo-wound pipes 4 and sand 300, can be quickly erected and disassembled after use, saving on operating costs.

[0054] The above description is only a preferred embodiment of the present invention and does not limit the scope of patent protection of the present invention. Any equivalent structural transformation made by using the contents of the description and drawings of the present invention, directly or indirectly applied in other related technical fields, is also included in the scope of protection of the present invention.
