[0001] This utility model relates to the field of construction tool technology, specifically to a high-strength foundation pit support structure. Background Technology

[0002] High-strength foundation pit support structures can withstand external loads such as soil pressure and water pressure, ensuring project safety. In foundation pit engineering, the main function of the support structure is to prevent soil collapse and deformation, ensuring the stability and safety of the main structure. Simultaneously, it effectively controls the groundwater level, preventing flooding and significantly impacting construction progress and cost. Rapid urban development: With the acceleration of urbanization, underground space is being utilized more and more extensively. The construction of high-rise buildings, subways, and underground passages has led to a continuous expansion in the scale of foundation pit projects, placing increasingly higher demands on support structures. In areas with complex geological conditions, such as soft soil areas and karst areas, foundation pit support is even more challenging. These areas require more advanced and reliable support structures to ensure project safety.

[0003] According to the patent document (authorization announcement number CN219825289U), the present invention includes: a protective plate, a support plate one, and a support plate two. Multiple protective plates are provided. Support plate one and support plate two are fixed to the rear surface of the protective plate. Multiple support plates one and two are provided. A mountain-shaped protrusion is integrally formed on the left side surface of the protective plate, and a mountain-shaped groove is formed on the right side surface of the protective plate. Each protective plate is connected to the other through the protrusion and groove. The cross-section of support plate one is L-shaped, and support plate two is T-shaped. Support plate one has fixing holes one, two, and three on its surface. Compared with the prior art, this invention has the following advantages: by providing support plate one, the strength of the foundation pit support is increased by the support plate one; by providing support plate two, the support plate two, together with support plate one, ensures the support strength of the protective plate.

[0004] However, the above-mentioned device still has shortcomings:

[0005] During installation, the ground may be too soft, causing the protective panel to sink, and the staff may not be able to detect and maintain the problem in time. Utility Model Content

[0006] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a high-strength foundation pit support structure, which solves the problem that during installation, the ground may be soft, causing the protective plate to sink, and workers cannot detect and maintain it in a timely manner.

[0007] To achieve the above objectives, this utility model proposes a high-strength foundation pit support structure, comprising a pair of protective plates, with a cutting workpiece fixedly connected to the bottom of each pair of protective plates. A first connecting block and a second connecting block are fixedly connected to one side of each pair of protective plates, and a connecting rod is provided between the first connecting block and the second connecting block. The two ends of the connecting rod are fixedly connected to the first connecting block and the second connecting block, respectively. A pair of connecting blocks are provided on the side of the protective plate near the first connecting block, and a connecting rod is fixedly connected between the pair of connecting blocks. An electric telescopic rod is provided on the side of the protective plate near the first connecting block, and the two ends of the electric telescopic rod are rotatably connected to the connecting rod and the connecting rod, respectively.

[0008] Preferably, one side of one of the protective plates is engraved with a protrusion, and the side wall of the other protective plate is engraved with a groove, wherein the protrusion is inserted into the groove.

[0009] Preferably, a support plate is provided on the side of the guard plate near the first connecting block, and a fixing hole is opened on the surface of the support plate, and a fixing pin is inserted into the fixing hole.

[0010] Preferably, a connecting plate is provided on the side of the guard plate near the support plate, the connecting plate is fixedly connected to the support plate, and the surface of the connecting plate is provided with a plurality of fixing threaded holes.

[0011] Preferably, the connecting block is fixedly connected between a pair of support plates.

[0012] Preferably, the internal thread of the fixed threaded hole is connected to a fixing screw.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] During installation, the guard plate is inserted into the ground, and the insertion depth is determined according to the ground conditions. After the cutting workpiece is fixed, the connecting block, the first connecting block, and other components are installed in sequence. Because the electric telescopic rod is telescopic, it can adapt to the position of the guard plate and provide a fixed support. In case of sinking danger, the guard plate can be pushed upward by activating the electric telescopic rod, which can effectively slow down the sinking speed of the guard plate and prevent it from sinking too quickly and causing incalculable dangerous consequences.

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] like Figure 1-3 As shown, the high-strength foundation pit support structure includes a pair of guard plates 1. A cutting tool 101 is fixedly connected to the bottom of each guard plate 1. A first connecting block 4 and a second connecting block 41 are fixedly connected to one side of each guard plate 1. A connecting rod 42 is provided between the first connecting block 4 and the second connecting block 41, with both ends of the connecting rod 42 fixedly connected to the first connecting block 4 and the second connecting block 41, respectively. A pair of connecting blocks 3 are provided on the side of the guard plate 1 near the first connecting block 4, and a connecting rod 31 is fixedly connected between the pair of connecting blocks 3. An electric telescopic rod 43 is provided on the side of the guard plate 1 near the first connecting block 4. The electric telescopic rod 43 is externally connected to a pressure sensor and an alarm. Since the electric telescopic rod 43 is electrically driven, when the guard plate 1 sinks due to ground influence... When the electric telescopic rod 43 is carried by the guard plate 1, it compresses the guard plate 1. At this time, the pressure sensor receives the pressure information and transmits it to the alarm through an electrical signal, so that the alarm can sound an alarm in time to remind the staff that the guard plate 1 is sinking and that it needs to be dealt with in time. The two ends of the electric telescopic rod 43 are rotatably connected to the connecting rod 42 and the connecting rod 31 respectively. During installation, the guard plate 1 is inserted into the ground, and the insertion depth is determined according to the ground environment. After the cutter workpiece 101 is fixed, the connecting block 3, the first connecting block 4, and other components are installed in sequence. Because the electric telescopic rod 43 is telescopic, it can adapt to any position where the guard plate 1 is moved down and play a fixed support role.

[0021] This design allows for adjustment of the insertion depth of the guard plate 1 according to the actual ground conditions. This means that effective installation can be carried out in various geological conditions, whether it is soft soil, hard rock, or others. This flexibility improves the applicability of the equipment in various environments.

[0022] When the guard plate 1 is found to be sinking, the staff can promptly detect the problem with the alarm and then activate the electric telescopic rod 43 to extend it upwards. Because the support plate 2 has a large surface area, it is not easy for it to sink. Furthermore, the support plate 2 can be firmly fixed to the ground with the fixing pin 22, which plays the role of supporting the electric telescopic rod 43. After the staff activates the electric telescopic rod 43, it can provide the guard plate 1 with an upward force, which can greatly slow down the sinking speed of the guard plate 1 and provide more time for the staff to deal with the sinking problem.

[0023] One side of a guard plate 1 is engraved with a protrusion 102, and the side wall of the other guard plate 1 is engraved with a groove 103, with the protrusion 102 inserted into the groove 103.

[0024] A support plate 2 is provided on the side of the guard plate 1 near the first connecting block 4. A fixing hole 21 is provided on the surface of the support plate 2, and a fixing pin 22 is inserted into the fixing hole 21.

[0025] A connecting plate 23 is provided on the side of the guard plate 1 near the support plate 2. The connecting plate 23 is fixedly connected to the support plate 2. Several fixing threaded holes 231 are opened on the surface of the connecting plate 23. Fixing screws are connected to the fixing threaded holes 231 internally. The fixing threaded holes 231 are fixed to the guard plate 1 by fixing screws.

[0026] The connecting block 3 is fixedly connected between a pair of support plates 2, and the internal thread of the fixed threaded hole 231 is connected with a fixing screw.

[0027] Working principle: During installation, the guard plate 1 is inserted into the ground. The insertion depth is determined according to the ground environment. After the cutter workpiece 101 is fixed, the connecting block 3, the first connecting block 4 and other components are installed in sequence. Then, the electric telescopic rod 43 is adjusted to change its length so that it can form a triangular structure with the guard plate 1 and the support plate 2, thereby fixing and supporting the guard plate 1.

[0028] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
