[0014] The present application also discloses a method for supporting a stacked slope with seismic resistance function, including the following steps: S1: Construction preparation: Survey the geological conditions, topography, surrounding environment, etc. of the construction site, and carry out positioning and setting out to ensure the accurate position of the device. Pour the concrete frame with reinforced concrete and transport the precast concrete frame to the construction site; S2: Foundation treatment: Excavate the slope in layers, insert the grouting anchor into the slope, and carry out grouting treatment on the inside of the stacked slope through the grouting anchor to fill the small gaps in the stacked slope and improve the stability of the slope. During this process, the grout stopper prevents the slurry from overflowing through the hole, and at the same time, the second installation nut restricts the position of the grout stopper, and the positioning piece makes it difficult for the grouting anchor to leave the inside of the slope after insertion; S3: Installation module: Use lifting equipment to place the concrete frame in the predetermined position, insert the grouting anchor into the holes reserved inside the concrete frame, and fix it. Use the first installation nut to fix the position between the concrete frame and the grouting anchor, so that the concrete frame is firmly fixed on the slope surface; S4: Connecting Module: Adjacent devices are connected and fixed through an assembly structure. Meanwhile, by adjusting the lengths of the second damping spring and the first damping spring, the damping structure can compensate for errors. S5: Support Measures: The rock and soil of the slope are squeezed by the concrete frame and grouting bolts, making the rock and soil of the slope stable and not prone to loosening. Meanwhile, the wire mesh blocks the surface rock and soil of the slope from sliding down. The damping structure provides shock absorption and buffering at the connection of adjacent devices, and the drainage structure discharges the groundwater in the deep rock and soil of the slope.

[0015] Compared with the prior art, the present invention provides a stacked slope support device with seismic resistance function, having the following beneficial effects: 1. For the stacked slope support device with seismic resistance function, the push arm drives the moving seat to compress the second damping spring and the first damping spring, providing a buffering mechanism for the pressure borne by a single group of concrete frames, achieving an excellent seismic buffering effect, changing the force mode between the support modules, making the force distribution more uniform and dispersed, effectively alleviating the stress concentration phenomenon and local damage risk between the support modules, and being able to offset the deformation and displacement of the slope to a certain extent, thus greatly improving the stability and safety of the entire support structure. 2. For the stacked slope support device with seismic resistance function, by precisely embedding the first connecting block into the second connecting block and supplementing with fixing bolts to achieve a firm lock between the two, it greatly facilitates the assembly process of the device, significantly reducing the time and labor costs required for on-site installation. At the same time, it can quickly replace damaged components, effectively shortening the maintenance cycle and reducing the maintenance cost. 3. For the stacked slope support device with seismic resistance function, by inserting the pipe into the specified soil layer depth, the excess water in the rock and soil can smoothly penetrate into the pipe through the stainless steel filter screen and is finally discharged by the drain pipe. This not only effectively prevents the softening of the slope soil due to excessive water saturation, ensuring the strength and stiffness of the soil are maintained, but also significantly reduces the hydrostatic pressure and hydrodynamic pressure generated by groundwater on the slope, providing a solid guarantee for the long-term stability of the slope.

[0022] As Figure 4 and Figure 5As shown, in one embodiment: The assembly structure 6 includes a first connection block 605 rotatably connected to one side of a set of push arms 209, a second connection block 609 rotatably connected to one side of another set of push arms 209 and slidably connected to the first connection block 605, a rubber pad 608 installed between the second connection block 609 and the first connection block 605, a fixing bolt 607 inserted into one side of the second connection block 609, a nut 606 arranged on one side of the first connection block 605 and threadedly connected to the fixing bolt 607, a guide block 604 fixed to one side of the second connection block 609 and the first connection block 605, a protective shell 601 sleeved outside the second connection block 609 and the first connection block 605, a guide groove 603 opened inside the protective shell 601 and slidably connected to the guide block 604, and a buckle 602 fixed to one side of the protective shell 601; By inserting the first connection block 605 into the second connection block 609 and inserting the fixing bolt 607 to lock and fix the second connection block 609 and the first connection block 605, the installation process can be significantly simplified, and the time and labor costs required for on-site installation can be reduced.

[0023] As Figure 7 and Figure 8 As shown, in one embodiment: The drainage structure 7 includes a connecting frame 702 fixed to the inner bottom end of the steel frame 4, an installation sleeve 703 rotatably connected inside the connecting frame 702, a locking bolt 704 threadedly connected to one side of a set of connecting frames 702 and connected to the installation sleeve 703, a drain pipe 701 inserted into the installation sleeve 703, an insertion pipe 706 fixed to the bottom end of the drain pipe 701, a stainless steel filter screen 707 fixed to the outside of the insertion pipe 706, a spiral blade 705 fixed to the outer wall of the insertion pipe 706 and connected to the drain pipe 701, and a support block 708 fixed inside the drain pipe 701 and the insertion pipe 706; By inserting the insertion pipe 706 to a specified depth, the water in the soil can seep into the insertion pipe 706 through the stainless steel filter screen 707 and be discharged by the drain pipe 701, preventing the slope soil from softening due to excessive moisture.

[0024] As Figure 1 As shown, in one embodiment: The concrete frame 1 is a reinforced concrete structure, and the steel frame 4 and the steel bars inside the concrete frame 1 are integrally welded.

[0025] As Figure 6 As shown, in one embodiment: Buffer pads are installed at both ends of the second shock-absorbing spring 205 and the first shock-absorbing spring 202, and the push arms 209 are symmetrically distributed on the vertical center line of the concrete frame 1; By using the buffer pads, the direct contact between parts is reduced, thereby reducing wear and the transmission of vibration and impact to the fixing frame 201.

[0026] As Figure 4 and Figure 5As shown, in one embodiment: A snap 602 forms a snap structure with a second connection block 609 and a first connection block 605. When the snap 602 is snap-connected to the second connection block 609 and the first connection block 605, the second connection block 609 and the first connection block 605 are completely placed inside the protective shell 601. The protective shell 601 protects the second connection block 609 and the first connection block 605, and at the same time, the snap 602 is responsible for fixing the position of the protective shell 601.

[0027] As Figure 7 and Figure 8 As shown, in one embodiment: A number of groups of stainless steel filters 707 are installed on the outer side of the insertion tube 706, and the number of groups of stainless steel filters 707 are evenly distributed on the outer side of the insertion tube 706. The multi-group stainless steel filters 707 accelerate the entry of groundwater into the insertion tube 706, improving the drainage effect.

[0028] Specifically, when the anti-seismic function-loaded accumulation slope support device is in use: First, a concrete frame 1 is pre-cast using reinforced concrete and then transported to the construction site. Next, the grouting anchor rod 3 is inserted into the slope, and grouting operations are carried out inside the accumulation slope through the grouting anchor rod 3 to fill the small cracks in the slope. During this process, the function of the grout stopper 10 is to prevent the slurry from overflowing from the hole, while the second installation nut 9 is used to fix the position of the grout stopper 10, and the positioning piece 12 ensures that the grouting anchor rod 3 is not easily detached after being inserted into the slope. After that, the concrete frame 1 is placed at the predetermined position using lifting equipment, enabling the grouting anchor rod 3 to be inserted into the holes reserved inside the concrete frame 1 and fixed. At the same time, the first installation nut 8 locks the position between the concrete frame 1 and the grouting anchor rod 3 to ensure that the concrete frame 1 can be firmly fixed on the slope surface. To connect and fix adjacent devices, we use the assembly structure 6. In addition, by adjusting the lengths of the second shock-absorbing spring 205 and the first shock-absorbing spring 202, the shock-absorbing structure 2 can compensate for the spacing error of the assembly structure 6. Through the combined action of the concrete frame 1 and the grouting anchor rod 3, the rock and soil of the slope are squeezed, thereby enhancing the stability of the slope rock and soil and preventing it from loosening. At the same time, the wire mesh 5 can prevent the rock and soil on the surface of the slope from sliding down, the shock-absorbing structure 2 can provide shock-absorbing and buffering effects at the joints of adjacent devices, and the drainage structure 7 is responsible for discharging the groundwater in the deep rock and soil of the slope; When prefabricating the concrete frame 1, the fixing frame 201 is directly connected to the steel bars inside the concrete frame 1, so that after the concrete frame 1 is poured, the connection between the fixing frame 201 and the concrete frame 1 is stable and not easy to loosen and fall off. When vibration occurs or local deformation occurs on the slope, the distance between adjacent two sets of devices changes, causing the assembly structure 6 to pull the push arm 209 to flip and move, and the push arm 209 to push the moving seat 204 to slide and flip a certain angle on the outer wall of the moving rod 203. At the same time, the moving seat 204 pushes the assembly structure 6 to move through the push arm 209, compensating for the distance between two sets of concrete frames 1. At the same time, the moving seat 204 squeezes or stretches the second shock-absorbing spring 205 and the first shock-absorbing spring 202, buffering the pressure on a single set of concrete frames 1, reducing the stress on the concrete frame 1, and reducing the impact of vibration and shock on the concrete frame 1. By rotating the screw cap 208 to push the support plate 206 to squeeze the second shock-absorbing spring 205, the position of the moving seat 204 and the tightness of the first shock-absorbing spring 202 and the second shock-absorbing spring 205 are adjusted. By moving the support plate 206 on the surface of the concrete frame 1, one end of the moving rod 203 is supported, so that when pressure is applied, the moving rod 203 is not easily bent and deformed; When assembling the device, by pulling the first connecting block 605 and the second connecting block 609 of adjacent two sets of devices to move, forcing the first connecting block 605 and the second connecting block 609 to drive the second shock-absorbing spring 205 or the first shock-absorbing spring 202 to contract through the push arm 209 and the moving seat 204. Immediately insert the first connecting block 605 into the second connecting block 609, align the through holes inside the first connecting block 605 and the second connecting block 609, insert the fixing bolt 607 into the through holes of the second connecting block 609 and the first connecting block 605, and install a nut 606 on the outside of the fixing bolt 607 to lock and fix the second connecting block 609 and the first connecting block 605, connecting and fixing adjacent two sets of devices. Cover the protective shell 601 on the outside of the second connecting block 609 and the first connecting block 605, and make the buckle 602 embed into the grooves on one side of the second connecting block 609 and the first connecting block 605, so that the protective shell 601 protects the second connecting block 609 and the first connecting block 605, making the second connecting block 609 and the first connecting block 605 not easily rusted, facilitating the disassembly and replacement of the assembly structure 6. The installation of the protective shell 601 is guided by sliding the guide groove 603 on the outside of the guide block 604; Adjust the angle of the installation sleeve 703 according to the inclination angle of the accumulation body slope to ensure that after the drain pipe 701 is inserted, the accumulated water inside the slope can be drained out. Rotate the locking bolt 704 to lock and fix the angle of the installation sleeve 703. Insert the insertion pipe 706 into the installation sleeve 703 until the insertion pipe 706 contacts the geotechnical grouting anchor 3. By rotating the drain pipe 701, the spiral blade 705 drills into the soil and drives the insertion pipe 706 to move into the geotechnical interior, so that the insertion pipe 706 reaches the specified depth. During this process, the installation sleeve 703 guides the movement of the drain pipe 701, making it difficult for the drain pipe 701 to tilt and deviate. Support the drain pipe 701 and the insertion pipe 706 through the support block 708, making it difficult for the drain pipe 701 and the insertion pipe 706 to be indented inward under pressure. When the moisture content inside the slope is relatively high, the moisture in the geotechnical soil seeps into the insertion pipe 706 through the stainless steel filter screen 707 and is discharged by the drain pipe 701, thereby reducing the moisture content inside the slope. The large-volume rocks can be directly blocked from contacting the insertion pipe 706 by the spiral blade 705, preventing the insertion pipe 706 from being damaged due to pressure.

[0029] As mentioned above, it is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.

10. A method for supporting a slope of an accumulation body with earthquake resistance according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1: Construction preparation: Survey the geological conditions, topography, surrounding environment, etc. of the construction site, and perform positioning and layout to ensure the accurate position of the device, use reinforced concrete to cast the concrete frame (1), and transport the prefabricated concrete frame (1) to the construction site; S2: foundation treatment: excavating the slope in layers, inserting the grouting anchor rod (3) into the slope, and performing grouting treatment on the inside of the accumulation body slope through the grouting anchor rod (3) to fill the small gaps in the accumulation body slope and improve the stability of the slope. During this process, the grouting stopper (10) prevents the grouting material from overflowing through the hole. At the same time, the second mounting nut (9) limits the position of the grouting stopper (10), and the positioning piece (12) makes it difficult for the grouting anchor rod (3) to leave the inside of the slope after being inserted; S3: Installation module: Use a lifting device to place the concrete frame (1) at a predetermined position, insert the grouting anchor rod (3) into a hole reserved inside the concrete frame (1), and fix it, and use a first mounting nut (8) to fix the position between the concrete frame (1) and the grouting anchor rod (3), so that the concrete frame (1) is firmly fixed on the slope surface; S4: connecting module: connecting and fixing adjacent devices through the assembly structure (6), and adjusting and installing the length of the second shock absorbing spring (205) and the first shock absorbing spring (202) so that the shock absorbing structure (2) can compensate for the error; S5: Support measures: The rock and soil of the slope are squeezed by the concrete frame (1) and the grouting anchor rods (3) to make the rock and soil of the slope stable and not easy to loosen. At the same time, the wire mesh (5) prevents the surface rock and soil of the slope from sliding downward. The connection between adjacent devices is shock-absorbing and buffered by the shock-absorbing structure (2). The groundwater in the deep rock and soil of the slope is discharged by the drainage structure (7).
