[0031] Support plate 100, the support plate 100 is provided with a plurality of support plates 100, and the adjacent support plates 100 are rotatably connected;

[0032] The sealing gasket 400 is installed at the joint of the two support plates 100 to seal the gap between the two support plates 100.

[0033] The flow guide assembly includes a flow guide groove 200, and the bottom end of the flow guide groove 200 is provided with a drainage hole 210 outward along the thickness direction of the support plate 100.

[0034] The support assembly includes a support leg 310 installed on the outer wall of the support plate 100.

[0035] The specific use scenario of this embodiment is: during the construction of a deep foundation pit, when facing groundwater seepage or rainwater accumulation, the support plate 100 serves as the protective main body of the side wall of the foundation pit. Since the adjacent support plates 100 are connected by rotation, they can adapt to a certain degree of deformation of the foundation pit, maintain the integrity of the structure, the sealing gasket 400 is tightly installed at the joint of the support plate 100, effectively sealing the gap, preventing water from seeping into the interior of the foundation pit from the gap between the plates, and playing a key anti-seepage role. The flow guide groove 200 in the flow guide assembly receives water seeping or flowing from the side wall of the foundation pit. After the water is collected in the flow guide groove 200, it is discharged to the outside of the foundation pit along the thickness direction of the support plate 100 through the drainage hole 210 at the bottom end, realizing the function of flow guide and drainage. The support leg 310 of the support assembly is installed on the outer wall of the support plate 100 and penetrates into the soil body, providing support for the support plate 100, resisting the lateral pressure of the soil body of the side wall of the foundation pit, and ensuring the stability of the support structure, preventing the deformation or collapse of the support plate 100.

[0036] Embodiment two: as Figures 3-5 The support plate 100 is rectangular, a first ear hook 110 is welded and connected to one side of the outer wall of the support plate 100, and a plurality of first ear hooks 110 are arranged. A second ear hook 120 is fixedly installed on the outer wall of the side of the support plate 100 away from the first ear hook 110, and a plurality of second ear hooks 120 are arranged. The top end and the bottom end of the second ear hook 120 are respectively provided with a third ear hook 130, and a counterbore 131 is formed in the inner wall of the top second ear hook 120. The first ear hook 110, the second ear hook 120, and the third ear hook 130 are matched and connected, the first ear hook 110, the second ear hook 120, and the third ear hook 130 are matched and connected, and the shaft pin 140 is installed. The top end of the shaft pin 140 is provided with a anti-loosening plate, the anti-loosening plate is matched and connected with the inner wall of the counterbore 131 for positioning, and the top outer wall of the anti-loosening plate is fixedly installed with a pull ring 141.

[0037] The specific use scene of this embodiment is that when installing and splicing the deep foundation pit supporting plate 100, the first ear hook 110 on one side of the supporting plate 100, the second ear hook 120 on the other side, and the third ear hook 130 at the top and bottom of the second ear hook 120 are matched with each other to align the corresponding ear hooks of adjacent supporting plates 100, the shaft pin 140 is inserted into the matching holes of the first ear hook 110, the second ear hook 120 and the third ear hook 130, the anti-falling plate at the top of the shaft pin 140 is clamped and positioned with the counterbore 131 on the inner wall of the top second ear hook 120 to prevent the shaft pin 140 from falling off, thereby realizing stable rotary connection between the supporting plates 100. This connection method not only facilitates the installation and disassembly of the supporting plate 100, but also enables the supporting plate 100 to adapt to the deformation of the foundation pit by rotating and adjusting when subjected to soil pressure, thereby ensuring the overall stability of the supporting structure and providing a stable foundation for the subsequent function components such as anti-seepage and flow guiding.

[0038] Embodiment three: Figure 3 and Figure 4 The flow guiding groove 200 is provided on the inner side wall of the supporting plate 100, and the flow guiding groove 200 is provided with a plurality of grooves. The bottom end of the flow guiding groove 200 converges to the flow discharge hole 210, and the outer wall of the flow discharge hole 210 is fixedly installed with a flow guiding pipe (not shown in the figure).

[0039] The specific use scene of this embodiment is that when water seeps into the side wall of the foundation pit during the construction of the foundation pit, the plurality of flow guiding grooves 200 provided on the inner side wall of the supporting plate 100 will collect water like a “channel”. Due to the design and layout of the flow guiding groove 200, the water flow will converge to the bottom end along the groove body, and finally flow to the flow discharge hole 210. The flow guiding pipe installed on the outer wall of the flow discharge hole 210 guides the water flow collected here to the designated drainage position outside the foundation pit, avoiding the accumulation of water in the foundation pit. Through this organized flow guiding and drainage method, the water level in the foundation pit is effectively reduced, the soaking and pressure of water on the soil of the side wall of the foundation pit are reduced, the safety of the construction of the foundation pit is ensured, and the stability and anti-seepage effect of the supporting structure are prevented from being affected by excessive water.

[0040] Embodiment four: Figure 2 and Figure 3 The outer wall of the sealing gasket 400 is sealingly connected with the connection part of the two adjacent supporting plates 100, and the sealing rubber edges 410 are fixedly installed on the outer walls of the two sides of the sealing gasket 400.

[0041] The insertion grooves 150 are provided on the inner walls of the two sides of the supporting plate 100, and the sealing rubber edges 410 are sealingly and insertingly connected with the insertion grooves 150 at the connection part of the two supporting plates 100.

[0042] The specific use scenario of this embodiment is that when the deep foundation pit support plate 100 is spliced, the sealing gasket 400 is tightly attached to the connection between the adjacent support plates 100, and the sealing rubber edges 410 on both sides are precisely inserted into the insertion slots 150 in the inner walls of the support plates 100. When the support plates 100 are slightly displaced due to soil pressure or external factors, the sealing insertion structure between the sealing rubber edges 410 and the insertion slots 150 can effectively compensate for the gap changes and always maintain good sealing effect. The sealing gasket 400 and the sealing rubber edges 410 work together like a waterproof barrier to prevent water from seeping into the foundation pit from the spliced joints of the support plates 100, ensuring that the inside of the foundation pit is dry, reducing safety hazards such as soil softening and collapse caused by water seepage, and improving the anti-seepage performance and overall safety of the support structure.

[0043] Embodiment five: as Figure 4 and Figure 5 The support assembly includes a first movable block 300 and a second movable block 340, which are welded to the outer wall of the support plate 100. The inner wall of the first movable block 300 is rotatably connected to the support leg 310 through the first insertion rod 320, and the bottom end of the support leg 310 is welded to the support angle 330. The support angle 330 is fixedly connected to the ground outside the deep foundation pit through the foundation bolt 331. The inner wall of the second movable block 340 is rotatably connected to the support rod 350 through the second insertion rod 360, and the end of the support rod 350 is provided with a clamping plate 351. The clamping plate 351 is connected to the support leg 310 through the third insertion rod 370.

[0044] The specific use scenario of this embodiment is that the first movable block 300 and the second movable block 340 of the support assembly are welded to the outer wall of the support plate 100, serving as the connection basis of the support structure. The support leg 310 is rotatably connected to the first movable block 300 through the first insertion rod 320, and can be flexibly adjusted in angle. The bottom end of the support leg 310 is fixedly connected to the ground outside the deep foundation pit through the foundation bolt 331, and the soil lateral pressure on the support plate 100 is transmitted to the foundation, providing basic support for the support plate 100. At the same time, the support rod 350 is rotatably connected to the second movable block 340 through the second insertion rod 360, and the clamping plate 351 at the end of the support rod 350 is connected to the support leg 310 through the third insertion rod 370, forming a triangular support structure. When the support plate 100 is subjected to a large soil pressure, the triangular support structure can further disperse the pressure and enhance the support stability, preventing the support leg 310 or the support plate 100 from deforming or overturning, and ensuring the stability and safety of the deep foundation pit support structure during the entire construction process.

[0045] The utility model discloses a working principle is: the technical personnel in the field uses, and the support plate 100 is spliced through the rotation connection and ear hang, axle pin etc. component, can adapt to the deformation of foundation pit, and also convenient to install dismounting, the sealing washer 400 and the sealing rubber edge 410 fill the interstice between the board, and the water flow seepage path is blocked, and the diversion groove 200 collects the seepage of foundation pit side wall, and is discharged through the outflow hole 210 and the diversion pipe, and the water level of foundation pit is reduced, in the support assembly, and the support leg 310 provides the foundation support to the deep soil body, and forms the triangle stable structure with the support rod 350, and the soil body side pressure is dispersed, and the overall stability is strengthened, and each assembly cooperates with each other, guarantees the foundation pit construction safety, prevents the seepage, collapse and other risks.
