Longitudinal retaining bars are provided on the surface of the slope, and the longitudinal retaining bars are fitted on the outer side of the ends of the anchor rods. A transverse retaining bar is provided between two adjacent ends of the anchor rods in the horizontal direction. The ends of the anchor rods are provided with a clamping component for pressing and fixing the longitudinal retaining bars and transverse retaining bars towards the slope.

[0007] Furthermore, the clamping assembly has a pressure plate, and one side of the pressure plate has a circumferential array of support blocks. The support blocks are provided with a longitudinal mounting groove and a transverse mounting groove. The longitudinal mounting groove matches the longitudinal stop bar, and the transverse mounting groove matches the transverse stop bar.

[0009] Furthermore, the pressure plate is provided with an adjustable stop mechanism corresponding to the U-shaped buckle, which is used to lock or release the U-shaped buckle.

[0010] Furthermore, the adjustable stop mechanism has a stop block that matches the U-shaped buckle, and an adjusting bolt is rotatably provided on one side of the stop block. A support is threadedly connected to the outer side of the adjusting bolt, and the support is fixedly connected to one side of the pressure plate.

[0011] Furthermore, guide rods are symmetrically arranged on one side of the stop block, and the guide rods are slidably connected to the support.

[0012] Furthermore, a locking platform that matches the interior of the U-shaped buckle is fixedly provided on the side of the stop block opposite to the adjusting bolt.

[0013] Furthermore, a pad is fitted on the outside of the anchor rod on the side of the pressure plate opposite to the longitudinal retaining rod, and a locking nut is threaded onto the end of the anchor rod, which locks the pressure plate to the slope.

Anchor rods 3 are arranged in a matrix perpendicular to the surface of the slope 8. One end of the anchor rod 3 extends into the stable rock layer inside the slope 8, and the other end of the anchor rod 3 passes through the geotextile 1 and mesh 2. Longitudinal retaining bars 4 are provided on the surface of the slope 8. The longitudinal retaining bars 4 are fitted onto the outer side of the ends of the anchor rods 3. A transverse retaining bar 5 is provided between the ends of two adjacent anchor rods 3 in the horizontal direction. A clamping component 6 is provided at the end of the anchor rod 3 to press and fix the longitudinal retaining bars 4 and transverse retaining bars 5 towards the slope 8. In this embodiment, one end of the anchor rod 3 passes through the sliding surface of the slope and extends into the stable rock layer. The clamping component 6 and the anchor rod The end connection of anchor rod 3 applies pressure to the longitudinal retaining rod 4 and the transverse retaining rod 5, pressing and fixing the mesh plate 2 and geotextile 1 to the surface of the slope, maintaining slope stability, preventing landslides, and ensuring the safety of life and property. After the anchor rod 3 is installed, only the geotextile 1 and mesh plate 2 need to be laid on the surface of the slope 8, and then the longitudinal retaining rod 4, transverse retaining rod 5 and pressing component 6 can be assembled. There is no need for steel cage fabrication, formwork erection, concrete pouring and curing, which simplifies the construction process and shortens the construction cycle. The geotextile 1 and mesh plate 2 are pressed and fixed to the surface of the slope 8, which not only maintains the stability of the slope, but also has a good drainage effect. In addition, the geotextile 1 can prevent the loss of fine soil particles during drainage.

[0025] In the above embodiments, the permeability coefficient of geotextile 1 is >10. -2 cm / s, ensuring effective slope drainage while preventing the loss of fine soil particles.

[0026] In some embodiments, such as Figure 3 and 4 As shown, the clamping assembly 6 has a pressure plate 61, and one side of the pressure plate 61 has a circular array of support blocks 62. The support blocks 62 are provided with a longitudinal mounting groove 64 and a transverse mounting groove 65. The longitudinal mounting groove 64 matches the longitudinal stop bar 4, and the transverse mounting groove 65 matches the transverse stop bar 5. The support block 62 has an isosceles right-angled triangular structure. The support block 62 and the pressure plate 61 are an integral structure. The support block 62 provides support between the longitudinal stop bar 4 and the transverse stop bar 5 to ensure the stability between the longitudinal stop bar 4 and the transverse stop bar 5.

[0029] In some embodiments, the adjustable stop mechanism 7 has a stop block 71 that matches the U-shaped buckle 51. An adjusting bolt 73 is rotatably provided on one side of the stop block 71. A support 72 is threadedly connected to the outer side of the adjusting bolt 73. The support 72 is fixedly connected to one side of the pressure plate 61. Rotating the adjusting bolt 73 causes the threaded structure between the adjusting bolt 73 and the support 72 to drive the stop block 71 to move, thereby causing the stop block 71 to abut or move away from the U-shaped buckle 51, thus locking or releasing the end of the crossbar 5.

[0030] In some embodiments, a guide rod 74 is symmetrically arranged on one side of the stop block 71. The guide rod 74 is slidably connected to the support 72. The stop block 71 is slidably connected to the support 72 through the guide rod 74, thereby improving the stability of the stop block 71.

[0031] In some embodiments, a locking platform 75 matching the interior of the U-shaped buckle 51 is fixedly provided on the side of the stop block 71 away from the adjusting bolt 73; during installation, the locking platform 75 is embedded into the interior of the U-shaped buckle 51, and the U-shaped buckle 51 is not easy to fall off the locking platform 75, thereby improving the stability of the connection between the adjustable stop mechanism 7 and the end of the crossbar 5.

[0032] In some embodiments, a pad 66 is fitted on the outside of the anchor rod on the side of the pressure plate 61 away from the longitudinal retaining rod 4, and a locking nut 67 is threaded on the end of the anchor rod 3, which locks the pressure plate 61 to the slope 8; the end of the anchor rod 3 is provided with an external thread that matches the locking nut 67.
