Technical Field
[0001] This utility model relates to the field of foundation pit protection fence technology, specifically a foundation pit excavation construction protection fence. Background Technology
[0002] Excavation of foundation pits is a fundamental step in the construction of buildings and municipal engineering projects, while protective fences are key facilities to ensure construction safety. Their core function is to prevent personnel and equipment from falling, isolate the construction area from the outside world, and prevent unauthorized personnel from accidentally entering and causing safety accidents.
[0003] However, existing technologies still have many defects in some similar structures when used in practice. For example, the protective fence for excavation of foundation pits needs stable support to ensure the safety of property and personnel. If the connection of the protective fence for excavation of foundation pits becomes loose or unstable, accidents may occur. The unstable connection of the security fence will bring great safety hazards. At the same time, during the subsequent excavation process, the unstable fence cannot effectively restrain the surrounding soil. When the unstable fence collapses, it is easy to cause lateral displacement of the foundation pit slope, which will lead to safety hazards.
[0004] To address the aforementioned problems, the inventors proposed a protective fence for foundation pit excavation construction. Utility Model Content

[0007] As a preferred technical solution of this application, the support component includes a connecting plate, both ends of which are rotatably connected to a rotating shaft, and both ends of the two rotating shafts are rotatably connected to a fixing block. One end of the two upper fixing blocks is fixedly connected to one end of the first upright plate, and the bottom ends of the two lower fixing blocks are fixedly connected to a base plate. Four third bolts arranged in a rectangular array are inserted at the top of the base plate.
[0008] With the above technical solution, after assembly, the fence is fixedly supported by the support assembly. The rotating shafts at both ends of the connecting plate in the support assembly are adjusted to a suitable angle, so that two of the upper fixing blocks are fixedly connected to one end of the first upright plate, ensuring that the connecting plate provides effective support for the fence. The bottom plate, which is fixedly connected to the bottom ends of the two lower fixing blocks, is placed on the ground around the foundation pit. Four third bolts distributed in a rectangular array are inserted into the top of the bottom plate and screwed into the ground, so that the bottom plate is firmly fixed to the ground. Thus, the support assembly provides stable support for the entire fence, which can effectively ensure that the fence can always provide stable support during the foundation pit excavation process.
[0009] As a preferred technical solution of this application, a protective net is fixedly connected between the first upright plate and the second upright plate.
[0010] Through the above technical solution, the protective netting fixedly connected between the first and second uprights can form a protective barrier.
[0011] As a preferred technical solution of this application, the outer surface of the insertion rod is in contact with the inner wall of the hole.
[0012] By using the above technical solution, the plug rod fixedly connected to one end of the spring is pushed out of the through groove and inserted into the corresponding holes at both ends of the card plate, thus initially achieving the positioning and fixing of the first upright plate and the second upright plate.
[0013] As a preferred technical solution of this application, the card plate is H-shaped.
[0014] Using the above technical solution, an I-shaped card is inserted between the first and second upright plates.
[0015] As a preferred technical solution of this application, the outer surface of the card plate is respectively attached to the inner wall of the first upright plate and the second upright plate.
[0016] Through the above technical solution, the outer surface of the card plate is more stably connected to the first and second vertical plates respectively.
[0017] As a preferred technical solution of this application, the top ends of the first baffle and the second baffle are threaded with a second bolt, and the bottom end of the second bolt is threadedly connected to the top end of the clamping plate.
[0018] By using the above technical solution, the second bolt is threaded into the first baffle and the second baffle and threadedly connected to the top of the clamping plate, thereby further enhancing the connection stability between the first and second vertical plates and the clamping plate.
[0019] As a preferred technical solution of this application, four third bolts arranged in a rectangular array are inserted at the top of the base plate.
[0020] Using the above technical solution, four third bolts arranged in a rectangular array are inserted into the top of the base plate and screwed into the ground to firmly fix the base plate to the ground.

[0032] Example: Figure 1-5 As shown, this utility model provides a protective fence for foundation pit excavation construction, including multiple first upright plates 1, a second upright plate 2 at one end of the first upright plate 1, a protective net 3 fixedly connected between the first upright plate 1 and the second upright plate 2, a support component 4 fixedly connected to one side of the first upright plate 1 and the second upright plate 2, and a connecting component 5 provided between the first upright plate 1 and the second upright plate 2.
[0033] The connecting component 5 includes a clamping plate 51, which is I-shaped. The outer surface of the clamping plate 51 is in contact with the inner walls of the first upright plate 1 and the second upright plate 2. Multiple through slots 52 with equal spacing are opened at one end of the opposite side of the first upright plate 1 and the second upright plate 2. A spring 53 is fixedly connected to one side of the inner wall of the multiple through slots 52. A plug rod 54 is fixedly connected to one end of the multiple springs 53. Multiple holes 55 with equal spacing are opened at both ends of the clamping plate 51. The outer surface of the plug rod 54 is in contact with the inner wall of the hole 55. A first baffle 56 is rotatably connected to the top of the first upright plate 1, and a second baffle 57 is rotatably connected to the top of the second upright plate 2. A second bolt 58 is threaded into the top of the first baffle 56 and the second baffle 57. The bottom end of the second bolt 58 is threaded to the top of the clamping plate 51.
[0034] The second bolt 58 is threaded into the first baffle 56 and the second baffle 57 and threadedly connected to the top of the clamping plate 51, further strengthening the connection stability between the first upright plate 1 and the second upright plate 2 and the clamping plate 51. The protective net 3 fixedly connected between the first upright plate 1 and the second upright plate 2 can form a protective barrier.
[0035] The support assembly 4 includes a connecting plate 41, with a rotating shaft 42 rotatably connected to both ends of the connecting plate 41.

The first baffle 56, which is rotatably connected to the top of the first upright plate 1, and the second baffle 57, which is rotatably connected to the top of the second upright plate 2, are rotated to a horizontal state so that the tops of the two are aligned. The second bolt 58 is threaded into the first baffle 56 and the second baffle 57 and threadedly connected to the top of the clamping plate 51. This further strengthens the connection stability between the first upright plate 1, the second upright plate 2 and the clamping plate 51. The protective net 3, which is fixedly connected between the first upright plate 1 and the second upright plate 2, can form a protective barrier, thereby effectively strengthening the stability of the connection points between the fences and preventing people and objects from falling into the foundation pit.
[0038] After assembly, the fence is fixedly supported by the support component 4. The rotating shaft 42 connected to both ends of the connecting plate 41 in the support component 4 is adjusted to a suitable angle so that the two upper fixing blocks 43 are fixedly connected to one end of the first upright plate 1, ensuring that the connecting plate 41 provides effective support for the fence. The bottom plate 44, which is fixedly connected to the bottom ends of the two lower fixing blocks 43, is placed on the ground around the foundation pit. The four third bolts 45, which are distributed in a rectangular array, are inserted into the top of the bottom plate 44 and screwed into the ground to firmly fix the bottom plate 44 to the ground. Thus, the support component 4 provides stable support for the entire fence, thereby effectively ensuring that the fence can always provide stable support during the foundation pit excavation process.
