[0021] As Figures 1 to 4 shown, an embodiment of the present invention provides a foundation pit support device, including: a support plate 1, a bottom plate 2, and a hinge plate 3. One side of the hinge plate 3 is fixedly connected to the lower part of the support plate 1, and the other side of the hinge plate 3 is connected to the upper part of one side of the bottom plate 2 through a hinge. The upper part of the other side of the bottom plate 2 is connected to the upper part of the support plate 1 through a telescopic rod 4; connection blocks 5 are provided on both sides of the support plate 1, and the support plates 1 are connected to each other through a connection strip 6. The connection strip 6 is in a C shape, and the inner side of the connection strip 6 is stuck on the outer periphery of the connection block 5.

[0022] After removing the rotating shaft on the hinge between the support plate 1 and the bottom plate 2, the support plate 1 and the bottom plate 2 can be separated, which is convenient for transportation. When carrying out support, connect the support plate 1 and the bottom plate 2. After placing the support plate 1 at the position where support is needed, unfold the bottom plate 2 and press the bottom plate 2 into the soil so that the positioning pins 8 on the bottom plate 2 are inserted into the soil. Then, connect the two ends of the telescopic rod 4 to the bottom plate 2 and the support plate 1 respectively through a pin shaft, and adjust the length of the telescopic rod 4 so that the support plate 1, the bottom plate 2, and the telescopic rod 4 form a triangle, improving the stability of the support device. After installing the first support plate 1, the subsequent support plates 1 are installed close to the side of the support plate 1, and then the two sides of the two support plates 1 are connected through the connecting strip 6 with a C-shaped structure. Through the mutual connection of multiple support plates 1, the side wall of the foundation pit can be effectively supported to prevent the side wall of the foundation pit from collapsing.

[0023] When connecting the support plate 1 through the connecting strip 6, make the connecting blocks 5 on the side of the support plate 1 flush, and then put the connecting strip 6 on the connecting blocks 5. The connecting blocks 5 enter the connecting strip 6 through the notches 7, and then press down the connecting strip 6. Use the inner wall of the connecting strip 6 to clamp both sides of the connecting blocks 5 to connect the support plates 1 to each other. Through the connection method of the connecting strip 6, the connection between the support plates 1 can be connected and separated at any time and independently, which is convenient for the installation and disassembly of the support device, improving work efficiency and installation convenience.

[0024] In a preferred embodiment, as Figure 1 shown, there are multiple connecting blocks 5, and the multiple connecting blocks 5 are arranged at intervals along the edges on both sides of the support plate 1. The support plate 1 can be evenly clamped on the side through the connecting strip 6, so that the support plates 1 can be firmly connected. And the lowermost connecting block 5 is connected to the upper end surface of the hinge plate 3. When connecting the support plate 1, after knocking the connecting strip 6 to the bottom, the connecting strip 6 can effectively clamp the connecting blocks 5 to connect the support plates 1 to each other.

[0025] [[ID=eleven]]In a preferred embodiment, as Figure 3 and Figure 4 shown, the connecting strip 6 is provided with notches 7 at intervals. The length of the notches 7 is greater than or equal to the length of the connecting blocks 5. The connecting blocks 5 can conveniently enter the connecting strip 6 through the notches 7. After knocking the connecting strip 6, the connecting strip 6 moves downward, making the notches 7 and the connecting blocks 5 misaligned. The connecting blocks 5 are locked by the non-notch positions on the connecting strip 6, so that the connecting strip 6 only needs to move a short distance to fix the support plate 1, which is convenient for the disassembly and assembly of the support plate 1.

[0026] In a preferred embodiment, multiple positioning pins 8 are provided at the lower part of the bottom plate 2. The positioning pins 8 are vertically fixed on the lower end surface of the bottom plate 2, and the sharp ends of the positioning pins 8 face downward. The positioning pins 8 can be inserted into the soil to increase the stability of the bottom plate 2 and prevent the bottom plate 2 from sliding.

[0027] In a specific embodiment, the support plate 1 is provided with multiple longitudinal folds, which can improve the bending resistance and prevent the support plate 1 from deformation during support. A crossbeam 9 is provided on the upper part of the support plate 1, and the crossbeam 9 is connected to the upper part of one side of the base plate 2 through a telescopic rod 4, so that the support plate 1, the base plate 2, and the telescopic rod 4 form a triangle, thereby improving the stability of the support device. The crossbeam 9 can make the folded support plate 1 evenly stressed, avoid deformation of the support plate 1 due to uneven force, and improve the support capacity of the support plate 1.

[0028] In a preferred embodiment, the telescopic rod 4 includes a first screw 41, a second screw 42, and a sleeve 43. The first screw 41 is connected to the second screw 42 through the sleeve 43. The first screw 41 is provided with a left-handed thread, and the second screw 42 is provided with a right-handed thread. The inner walls of both ends of the sleeve 43 are provided with corresponding internal threads. After rotating the sleeve 43, the sleeve 43 causes the first screw 41 and the second screw 42 to move axially through the left-handed internal thread and the right-handed internal thread respectively, thereby extending and retracting the telescopic rod 4. The thread has a self-locking function, which can maintain the length of the telescopic rod 4 and keep the support plate 1 at its angle.

[0029] Preferably, a rotating handle 44 is provided on the outside of the sleeve 43 to facilitate the rotation of the sleeve 43 to extend and retract the telescopic rod 4.

[0030] In a specific embodiment, a vertically mounted knocking rod is provided on the connecting strip 6 , so that the connecting strip 6 can be connected to or separated from the supporting plate 1 by hammering the knocking rod during installation or disassembly.

[0031] Of course, the present application may have many other implementations. Based on the present implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present application.
