Description

Technical Field

[0001] The utility model belongs to the technical field of foundation pit enclosure, in particular to a combined foundation pit enclosure structure. Background Art

[0002] A foundation pit retaining structure is a temporary or permanent structure used to support and stabilize the soil surrounding a foundation pit during construction. Its primary purpose is to prevent soil collapse, groundwater infiltration, and adverse impacts on surrounding buildings and roads during excavation. Foundation pit retaining structures are widely used in underground construction projects such as subways, underground garages, and foundation engineering.

[0003] At present, there are some enclosure structures on the market. For example, a construction enclosure structure is disclosed on the China Patent Network, and its announcement number is CN214006770U. This enclosure structure has the advantage of adjustable enclosure height, which makes the enclosure applicable to a variety of scenes. However, there are some defects and deficiencies that need to be improved: (1) The design of some existing enclosure structures is relatively complex. The relevant components are often connected and fixed by fasteners such as bolts. The installation and disassembly process requires the use of tools, which is relatively cumbersome, making it inconvenient to quickly maintain and replace the various components in the enclosure structure; (2) Some existing enclosure structures lack effective rain protection measures. When encountering rainy weather, rain will fall directly on the enclosure structure. Over time, it will cause the relevant components to rust, thereby affecting the service life of the enclosure structure; (3) Due to the structural design of some existing enclosure structures, when strong wind blows towards the enclosure plate, the wind force will directly act on the enclosure plate, which is difficult to decompose and weaken, and thus easily causes the enclosure structure to be blown down by the wind. Therefore, in response to the above problems, the combined foundation pit enclosure structure provided by the utility model is of great significance. Utility Model Content

[0031] Among them, a number of anti-slip pads 10 are provided on the bottom surface of the base 2. The anti-slip pads 10 are long strips and are equidistantly distributed linearly along the length direction of the base 2. The surface of the anti-slip pads 10 is engraved with herringbone anti-slip grooves. When the base 2 is placed on the ground of the foundation pit, the anti-slip grooves on the surface of each anti-slip pad 10 can increase the friction between the base 2 and the ground to play an anti-slip role, thereby effectively preventing the enclosure structure from slipping and displacement.

[0032] Among them, the fixing block 6 is L-shaped, and its width and thickness are respectively equal to the length and width of the inner wall of the fixing frame 3, and a pair of locking holes 11 are opened on the fixing block 6. The locking holes 11 are equal to the aperture of the through hole 4, and the center of each locking hole 11 corresponds one-to-one to the center of each through hole 4. The fixing block 6 can be inserted into and fit on the inner wall of the fixing frame 3. Through the mutual cooperation between the fixing block 6 and the fixing frame 3, the protective plate 5 can be fixedly installed between two adjacent columns 1 to form a protective structure. By pulling out the fixing block 6, the protective plate 5 can be removed from between the columns 1 to facilitate the transportation of the protective structure, and it can also facilitate the maintenance and replacement of related components.

The front end face of the column 1 is fixedly connected with a number of positioning blocks 13. The positioning blocks 13 and the positioning holes 12 are both rectangular, and their lengths and widths are equal. The center of each positioning block 13 corresponds one-to-one with the center of each positioning hole 12. When the locking plate 8 is attached to the front end face of the column 1, each positioning block 13 can be inserted into and attached to the inner wall of the corresponding positioning hole 12.

When the locking plate 8 is fixed on the column 1, each locking rod 14 can be aligned with and pass through the corresponding through hole 4 and locking hole 11 respectively. At this time, the guardrail 5 fixed between the adjacent columns 1 can be locked through the mutual cooperation between the locking rods 14, the through hole 4, and the locking hole 11 to prevent the guardrail 5 from detaching from between the columns 1. Compared with traditional connection and fixing methods, no fasteners such as bolts are required, and the installation and disassembly process does not require the aid of tools, which makes the installation and disassembly of the enclosure structure more convenient, and also facilitates the rapid maintenance and replacement of various components.

When strong wind blows towards the protective plate 5, the arc-shaped end faces of each wind block 7 can effectively decompose and weaken the wind force to prevent the wind force from directly acting on the protective plate 5 and causing the protective structure to be blown down by the wind. The surface of the reflective sticker 15 is coated with a fluorescent coating and fixed by glue or the like. When the protective structure is used at night, the fluorescent coating on the surface of each reflective sticker 15 can improve visibility and serve as a warning to prevent vehicles or pedestrians from colliding with the protective structure at night and in bad weather conditions.

[0036] Among them, the top end face of the rain shield 9 is in an inverted V shape, and a number of plug blocks 16 are fixedly connected to its bottom. A slot 17 is provided at the top of the column 1. The slots 17 and the plug blocks 16 are both rectangular, with the same number, length and width, and the center of each slot 17 corresponds one-to-one with the center of each plug block 16. The plug blocks 16 can be aligned and inserted into the corresponding slots 17. The rain shield 9 can be fixed to the top of the column 1 through the mutual cooperation between the plug blocks 16 and the slots 17. The rain shield 9 can cover the entire enclosure structure. When it rains, rainwater can flow to both sides along the surface of the rain shield 9. At this time, the rain shield 9 can play a role in sheltering from the rain to prevent rainwater from falling directly on the enclosure structure and causing rust on related components.

[0037] The standard parts used in the application documents can all be purchased from the market. All components in this application document can be customized according to the description in the specification and drawings.

[0038] The working principle of this utility model is:

[0039] When the present invention is in use, the fixing blocks 6 on both sides of the enclosure plate 5 can be inserted into the fixing frames 3 corresponding to the two adjacent columns 1 on both sides, so that the enclosure plate 5 can be fixedly installed between the two adjacent columns 1 through the mutual cooperation between the fixing blocks 6 and the fixing frames 3, thereby forming a enclosure structure. After the enclosure plate 5 and the column 1 are assembled, the locking plate 8 is fitted on the front end surface of the column 1, and each positioning block 13 is inserted into and fitted on the inner wall of the corresponding positioning hole 12, so that the locking plate 8 can be fixed on the column 1 through the mutual cooperation between the positioning block 13 and the positioning hole 12. When the locking plate 8 is fixed on the column 1, each locking rod 14 can be aligned with and pass through the corresponding through hole 4 and the locking hole 11 respectively. At this time, the enclosure plate 5 fixedly installed between the adjacent columns 1 can be locked through the mutual cooperation between the locking rod 14, the through hole 4, and the locking hole 11 to prevent the enclosure plate 5 from being locked. It is detached from the columns 1. Compared with the traditional connection and fixing method, no fasteners such as bolts are required, and the installation and disassembly process does not require the help of tools, which makes the installation and disassembly of the enclosure structure more convenient, and also facilitates the rapid maintenance and replacement of various components. The front and rear faces of the enclosure plate 5 are fixedly connected with a number of wind blocks 7. The surface of the wind block 7 is arc-shaped. When strong wind blows towards the enclosure plate 5, the arc-shaped end faces of each wind block 7 can effectively decompose and weaken the wind force to prevent the wind force from directly acting on the enclosure plate 5 and causing the enclosure structure to be blown down by the wind. A rain cover 9 is installed on the top of the column 1. The rain cover 9 can cover the entire enclosure structure. When encountering rainy weather, rainwater can flow to both sides along the surface of the rain cover 9. At this time, the rain cover 9 can play a role in sheltering from the rain to prevent rainwater from falling directly on the enclosure structure and causing rust on related components.
