Among them, the anti-slide pile or the prestressed cable, or the combination of the anti-slide pile and the prestressed cable, are commonly used supporting structures. The slope can be divided into landslide body and slide bed from outside to inside according to the geological composition, wherein the landslide body is also called unstable area, and the slide bed is called stable area in contrast. The anti-slide pile or the prestressed cable is used to support the sliding force of the landslide body by penetrating into the slide bed, and plays a role in stabilizing the slope.

[0004] The anti-slide pile is selected from wood pile, steel pile, concrete pile or reinforced (steel rail) concrete pile according to the thickness of the landslide body, the size of the thrust, the waterproof requirement and the construction condition, and the concrete pile is more commonly used.

[0039] The distance adjusting device is connected to the inner retaining wall 9 and is used to adjust the distance between the inner retaining wall 9 and the driving device.

[0040] The elastic device is preferably a spring 10, which always gives the inner retaining wall 9 an inwardly retracting force to maintain the stability of the device. The inner retaining wall 9 is provided with a plurality of sensor grooves 5, and the pressure detecting device is preferably a strain gauge, which is correspondingly installed in the sensor groove 5, so as to observe the pressure change of the slope body and the soil thereunder in real time during the test.

The plurality of telescopic rods 6 are connected to the plurality of inner retaining walls 9 one by one, and the telescopic rod 6 is preferably perpendicular to the inner retaining wall 9.

[0042] When the strain gauge arranged on the inner retaining wall 9 detects that the confining pressure applied by the soil changes, the control device controls the piston 8 to act, the piston 8 drives the telescopic rod 6 through the hydraulic cylinder 7, and the telescopic rod 6 adjusts the movement of the inner retaining wall 9 through telescopic adjustment, so as to adapt to the change of the confining pressure on the inner retaining wall 9.

[0043] The inner retaining wall 9 is provided with a plurality of rows and columns, and the left and right adjacent inner retaining walls 9 are connected through the elastic device, and the upper and lower adjacent inner retaining walls 9 are vertically stacked or flexibly connected. Each inner retaining wall 9 can be independently moved without mutual restriction, so as to maintain the integrity of the composite slope anti-slide pile supporting device.

[0044] Preferably, the number of the inner retaining wall 9, the strain gauge and the telescopic rod 6 is 16 respectively and is arranged one by one.

[0045] In the embodiment, the supporting device further comprises a communication device for communicating with a cloud base station, and the communication device is connected to the control device. The confining pressure of the soil detected by the strain gauge can be sent to the cloud base station through the communication device, so as to reduce the data processing time of the control device. After the data processing by the cloud base station, the control signal is sent back to the control device through the communication device, so as to make the control device send the action signal to the piston 8.

[0046] The light energy power generation system comprises a solar photovoltaic power generation panel 1 and an electric energy storage device 2, the solar photovoltaic power generation panel 1 is located above the surface soil layer, is connected to the electric energy storage device 2 through a wire 4, and the electric energy storage device 2 is connected to the distance adjusting device.

The light energy power generation system provides energy for the controllability of the hydraulic system, which uses clean and efficient solar energy, energy saving and environmental protection; compared with the traditional slope anti-slide pile, the slope anti-slide pile with the hydraulic system of the present application is more beneficial to the slope support and ramming of the area where the soil pressure is easy to change; the data detection system sets strain gauges to monitor some on-site data of the slope in real time, which is beneficial to subsequent maintenance and improvement work, and the three systems complement each other. A device has relatively comprehensive functions, which is of great significance for supporting and ramming the slope soil with variable pressure such as special soil, and disaster prevention and reduction of tunnel portal slope.

[0049] A supporting method of a composite slope anti-slide pile supporting device, comprising the following steps,

[0053] Specifically, when the confining pressure of the soil layer around the supporting device changes, the data monitoring system starts to work, the strain gauges on the sensor groove 5 will sense the collected pressure and deformation information of the soil layer and transmit it to the external cloud processing center by radio, the cloud processing center will transmit the processed information back to the control chip built in the anti-slide pile, after receiving the latest soil layer change information, the control chip will adjust the change of the hydraulic system according to the latest information, so as to provide pressure suitable for the surrounding soil. When the pressure of the surrounding soil layer increases, the control chip controls the 16-position hydraulic device to provide different pressures to the outer layer according to the latest soil layer change information. After receiving the remote regulated electric information, the piston 8 starts to descend, providing pressure to the hydraulic oil of the hydraulic cylinder 7, and the hydraulic oil of the hydraulic cylinder 7 transmits the pressure to the telescopic rod 6 perpendicular to the inner retaining wall 9, so as to balance the pressure of the external soil layer. The extension degree of the 16 different positions of the telescopic rod 6 is different due to the difference of the soil layer confining pressure, which can be automatically regulated by the control chip according to the electric information. The solar photovoltaic power generation panel 1 converts the electric energy into electric energy storage device 2 through wire 4, which provides energy guarantee for the above process.

[0054] The hydraulic system and the data monitoring system of the present application complement each other, and can slow down the change of the pressure and deformation of the soil body under different conditions, solve the problem of high cost of concrete material and fixed compressive strength, and can be applied to other engineering such as slope.
