Similarly, the longitudinally arranged steel strand 7 pulls the same row of anchor rods 1 in the longitudinal direction; the connecting node is connected to the end of the anchor rod 1 extending out of the foundation pit slope, and the connecting node is connected to the corresponding steel strand 7; the surface layer 5 is laid on the foundation pit slope, and the surface layer 5 is connected to the corresponding connecting node; the displacement meter 9 is connected to the connecting node, and the displacement meter 9 can be used to measure the changes in the soil surface between the connecting node and the foundation pit slope.

[0047] The anchor rod 1, surface layer 9, steel strand 7 and connection nodes in the slope support system of the present invention form a recyclable slope support structure, which can be recycled and used after the structural construction in the foundation pit is completed, saving costs and being green and environmentally friendly. The strain gauge 2 and displacement gauge 9 in the slope support system of the present invention form a monitoring device, which is built into the anchor rod 1 and the connection node, realizing the synchronous construction of the support structure and the monitoring device. After the construction is completed, the stability and deformation of the slope can be synchronously monitored, thereby improving the safety of the slope support system.

[0048] Preferably, the surface layer 5 is fixed to the foundation pit slope by cooperating with the anchor rod 1 and the connection node, and then the anchor rod 1 is fixed to the structure near the foundation pit slope by the steel strand 7 tied to the anchor rod 1, thereby supporting the slope soil.

[0049] Furthermore, if Fig.13 As shown, the slope support system of the present invention also includes a wireless signal system, which includes a wireless network transmitting device and a monitoring data receiving device. The wireless network transmitting device provides a wireless network for the monitoring equipment (strain gauge 2 and displacement gauge 9), and receives data collected by the monitoring equipment through the monitoring data receiving device. The monitoring data receiving device is connected to the strain gauge 2 and the displacement gauge 9 for communication, and can receive the monitoring data collected by the strain gauge 2 and the displacement gauge 9. The present invention realizes the wireless collection of discrete monitoring data in the support area through the wireless signal system, avoiding the interference of a large number of data collection lines with the construction of the support structure and the influence of line damage during construction on data collection.

[0050] The strain gauge 2 of the present invention is built into the middle section of the anchor rod 1 and is arranged close to the inner side of the anchor rod 1 along the length direction. The strain gauge 2 and the displacement gauge 9 are arranged on the anchor rod 1 and the connection node, so that the strain gauge 2 and the displacement gauge 9 can be installed synchronously with the anchor rod 1 and the connection node, and the strain gauge 2 and the displacement gauge 9 can be wirelessly connected to the external terminal through communication, so that the external terminal can receive the monitoring data information collected by the monitoring equipment.

The steel strands 7 can pass through the holes on the corresponding anchor rods 1, and two steel strands 7 are passed through the upper end of the same anchor rod 1, one of which is arranged horizontally and the other is arranged longitudinally.

[0052] Furthermore, the surface layer 5 is a flexible felt-like material, generally in strip shape, and adhesive strips are provided on both sides of the surface layer 5, which can be connected as a whole through the adhesive strips to achieve a repairable effect. A waterproof adhesive strip is provided on the inside of the adhesive strip to ensure that the surface layer 5 does not leak after being bonded as a whole.

[0053] See also Figure 1 In a specific embodiment of the present invention, the connection node includes a bottom film 3 mounted on the anchor rod, a cover plate 4 connected to the bottom film 3, a buckle plate 6 mounted on the anchor rod 1 and arranged above the cover plate 4, and a buckle 8 detachably mounted on the anchor rod 1. The surface layer 5 is sandwiched between the bottom film 3 and the buckle plate 6, wherein the cover plate 4 is embedded in the surface layer 5, and the surface layer 5 is provided with a through hole corresponding to the anchor rod 1. The surface layer 5 is mounted on the anchor rod 1 through the through hole, and the cover plate 4 is embedded in the through hole. During installation, the through hole of the surface layer 5 can be mounted on the corresponding anchor rod 1 first, and then the cover plate 4 can be mounted on the anchor rod 1, and then the cover plate 4 can be moved downward to embed the cover plate 4 into the corresponding through hole on the surface layer 5, and ensure that the cover plate 4 is buckled with the bottom film 3. Fig.10 As shown, four through holes are drilled on the surface layer 5 , and the surface layer 5 can be sleeved on four anchor rods 1 .

[0054] Preferably, if Figure 1 As shown, the bottom sheet 3, the cover plate 4, the gusset plate 6 and the buckle 8 are movable so that they can be installed and disassembled on the anchor rod 1. When recycling, the buckle 8, the gusset plate 6 and the steel strand 7 are removed from the anchor rod 1, and then the surface layer 5 is rolled up for recovery, and the bottom sheet 3 and the cover plate 4 are removed from the anchor rod 1, so as to achieve the recycling effect. During installation, the gusset plate 6 is fastened by the buckle 8, so that the gusset plate 6 and the bottom sheet 3 clamp the corresponding part of the surface layer 5 together, and the gusset plate 6 presses the corresponding part of the steel strand 7, thereby forming a reliable support structure system.

[0059] Furthermore, when the displacement meter 9 on the bottom film 3 is installed, the displacement meter 9 is debugged in advance and replaced in time when an abnormal signal occurs. By setting a perforation on the surface layer 5, it is convenient to put the surface layer 5 on the cover plate 4.

[0060] See also Figure 3 , the bottom sheet 3 is in a cross shape. Further, the cross-shaped arrangement of the bottom sheet 3 can provide a more stable support for the cover plate 4, so that the cover plate 4 is not prone to deviation after installation.

[0062] Furthermore, if Figure 2 As shown, the anchor rods 1 are vertically arranged with the steel strands 7, and the anchor rods 1 in the same row are tied together by the arranged steel strands 7.

[0063] See also Fig.12 In a specific embodiment of the present invention, a plurality of embedding grooves are provided on the surface layer 5, and the embedding grooves can be used for installing the photovoltaic panel 10. The photovoltaic panel 10 is electrically connected to the battery 11, and the battery 11 is electrically connected to the strain gauge 2 and the displacement gauge 9.

[0064] Furthermore, if Fig.12 As shown, by providing an embedding groove on the surface of the surface layer 5, the photovoltaic panel 10 can be embedded in the groove, and the wires corresponding to the photovoltaic panel 10 can also be fixed on its surface. By setting the photovoltaic panel 10 to convert heat energy into electricity, photovoltaic power generation can provide a stable power supply for the strain gauge 2 and the displacement gauge 9. Fig.13As shown, the photovoltaic panel 10 and the storage battery 11 of the present invention form a photovoltaic power supply system, which provides unit power supply for the monitoring equipment, avoids the complex interweaving of the power supply network, and realizes stable and reliable power supply. The embedded photovoltaic panel 10 can provide power to the monitoring equipment such as the strain gauge 2, displacement meter 9 and the wireless signal system nearby through a simple plug-in line connection.
