[0041] In the embodiment of the present invention, the anti-blocking detachable filtering mechanism 19 includes a circular hole 191 penetrating through the surface of the water filter rod 2, and an activated carbon permeable round block 192 is arranged inside the circular hole 191. The activated carbon material is permeable.

[0042] In the embodiment of the present invention, an iron block 193 is fixed on the surface of the activated carbon water-permeable round block 192 , and a slot 194 matching the iron block 193 is formed on the inner wall of the round hole 191 .

[0043] In the embodiment of the present invention, the inner wall of the circular hole 191 is provided with an arc groove 195 which is compatible with the iron block 193. The arc groove 195 is connected to the slot 194. A magnetic card block 196 is embedded in the inner wall of the arc groove 195.

[0044] In the embodiment of the present invention, the anti-loosening stabilizing mechanism 20 includes a mounting groove 201 provided on the surface of the anchor rod 1 , and a stabilizing block 202 is slidably mounted inside the mounting groove 201 .

[0045] In the embodiment of the present invention, a slide rail 203 is fixed on the surface of the stabilizing block 202, a slideway 204 adapted to the slide rail 203 is provided on the inner wall of the mounting groove 201, and a compression spring 205 is fixed on the surface of the stabilizing block 202 to facilitate rapid extrusion of the stabilizing block 202 out of the mounting groove 201.

[0046] In the embodiment of the present invention, one end of the compression spring 205 away from the stabilizing block 202 is fixedly connected to the inner wall of the mounting groove 201. The surface of the stabilizing block 202 is in a quarter arc shape, so that when the anchor rod 1 is inserted downward, the stabilizing block 202 can be smoothly retracted into the mounting groove 201.

[0047] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0048] During operation, the anchor rod 1 and the water filter rod 2 are rotated and fixed together by the first threaded column 4 and the first internal threaded groove 5, and the water filter rod and the prestressed rod 3 are rotated and fixed together by the second threaded column 6 and the second internal threaded groove 7, and then the prestressed pipe part of the anchor rod 1 to the prestressed rod 3 is completely buried inside the soil and stone slope, and then the tire is sleeved on the surface of the hollow pull tube 9, and the bottom of the tire is attached to the surface of the soil and stone slope, and the extension length of the internal threaded extension rod 17 is adjusted according to the tire size, and the lifting plate 187-1 is pulled upward to separate the second card groove 187-4 from the first card groove 187-3, thereby driving the symmetrical frame 187-2 to slide upward, and under the repulsive force of the second magnetic block 187-73, the two first magnetic blocks 187-72 drive the two arc-shaped card plates 187-71 to slide away from each other along the surface of the hollow pull tube 9, and then the symmetrical frame 187-2 is limited.

[0049] Then, the adjusting disk 186 is rotated by the push rod 188, and then the bidirectional threaded driving rod 182 is driven to rotate through the cooperation of the first bevel gear 184 and the second bevel gear 185, so that the two internally threaded extension rods 17 move away from or close to each other along the inner wall of the fixing rod 16, thereby completing the fixation of the tire. After adjustment, the two arc-shaped clamping plates 187-71 are pushed toward the middle, and then the lifting disk 187-1 is released. Under the elastic force of the tension spring 187-6, the symmetrical frame 187-2 is quickly reset, and then the lifting disk 187-1 is quickly reset, so that the second clamping groove 187-4 is engaged with the first clamping groove 187-3 to clamp the adjusting disk 186 to limit the position.

[0050] The water inside the soil and rock slope around the anchor rod can enter the water filter rod 2 after being filtered through the activated carbon permeable block 192. When the activated carbon permeable block 192 needs to be disassembled, the activated carbon permeable block 192 is pushed upward to make the iron block 193 disengage from the embedded groove 197, and then the activated carbon permeable block 192 is rotated so that the iron block 193 can move along the arc groove 195 to the slot 194, and then the activated carbon permeable block 192 can be taken out.

[0051] When burying the anchor rod, when the anchor rod 1 is inserted into the slope, the stabilizing block 202 will slide along the inside of the installation groove 201 due to the squeezing effect. After burying, under the elastic force of the compression spring 205, the stabilizing block 202 will be reset and inserted into the inside of the slope, effectively preventing the anchor rod 1 from being pulled out.

[0052] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
