[0001] The utility model relates to the technical field of full-strength weathered rock slope protection, in particular to a reinforcement structure suitable for full-strength weathered rock slope. Background Art
[0002] Slope protection is mainly divided into physical slope protection and ecological slope protection. Physical protection includes mortar-stone slope protection, shotcrete mortar and anchoring, which can well reinforce the slope to a certain extent. Ecological slope protection takes into account the stabilizing effect of vegetation on the slope. In some relatively stable slopes, ecological slope protection will be given priority. However, for unstable slopes, physical slope protection is generally used.

For fully weathered excavated slopes, the slopes are prone to damage and instability and collapse. Guangde area belongs to the mountainous area in southern Anhui, with abundant rainfall and rich groundwater. The fully weathered granite porphyry is relatively loose, and rainfall will further damage and deform the slope. In general, under the conditions of wind, sun, alternating cold and heat, and long-term harsh natural conditions, fully weathered slopes are more likely to collapse, forming natural disasters and posing a threat to people's lives and property.

[0025] The surfaces of the pointed steel pipe 2, the steel wire pipe 3 and the steel thorn structure 4 are all coated with an anti-corrosion coating to enhance the overall anti-corrosion performance.
[0026] The pointed steel pipe 2 has high strength and strong tensile strength, and can effectively enhance the stability of the slope and make the structure more stable.
[0027] The pointed steel pipe 2 is a hollow steel pipe with a diameter greater than or equal to 5 cm and a wall thickness greater than or equal to 0.4 cm, and the other end of the pointed steel pipe 2 is processed into a pointed tip.
[0028] The cross section of the steel wire tube 3 is square. The steel wire tube 3 with a square cross section is more stable than the steel wire tube 3 with a circular cross section, and is convenient for welding the circumferential steel wire ring 33 and the steel barb structure 4 .
[0029] The pointed steel pipe 2 includes a first pointed steel pipe 21 for anchoring a fully weathered rock slope and a second pointed steel pipe 22 for anchoring a strongly weathered rock slope. The length of the first pointed steel pipe 21 is twice that of the second pointed steel pipe 22 .
[0030] like Figure 2 and Figure 3 As shown, the steel wire tube 3 includes a first steel wire tube 31 for sleeve-connecting the first pointed steel tube 21 and a second steel wire tube 32 for sleeve-connecting the second pointed steel tube 22 . The length of the first steel wire tube 31 is twice that of the second steel wire tube 32 .
[0031] The length of the first steel wire tube 31 is 1 m, the length of the second steel wire tube 32 is 0.5 m, a circle of steel wire ring 33 is connected to the first steel wire tube 31 every 30 cm, and a circle of steel wire ring 33 is connected to the second steel wire tube 32 every 20 cm.
[0032] In this embodiment, the first steel wire tube 31 is connected with a circle of steel wire ring 33 at 20 cm, 50 cm and 80 cm away from one end thereof, and the second steel wire tube 32 is welded with a steel wire ring 33 at 10 cm and 30 cm away from one end thereof.
[0033] A mortar layer 6 fixed to the pointed steel pipe 2 is provided along the slope direction.
[0034] An anti-seepage layer 7 located at the top of the slope is arranged above the mortar layer 6. In the embodiment, the anti-seepage layer 7 uses original vegetation as slope protection, and is supplemented by lawn covering when necessary.
[0035] The steel barb structure 4 includes a connecting steel piece 41 and steel barbs 42. One end of the connecting steel piece 41 is fixedly connected to the wire ring 33. A plurality of steel barbs 42 are fixed on the connecting steel piece 41. The tips of the steel barbs 42 face the outside of the steel wire tube 3. The other end of the connecting steel piece 41 is inclined toward the center of the steel wire tube 3 and the steel barbs 42 on the connecting steel piece 41 are all located inside the steel wire tube 3.
[0036] like Figure 4 As shown, after the steel spike 42 is pushed out of the steel wire tube 3 by the pointed steel tube 2, the connecting steel part 41 is flush with the surface of the steel wire tube 3. One side of the steel spike 42 is vertical to the steel wire tube 3, and the other side is inclined to the surface of the steel wire tube 3 and forms an obtuse angle with the surface of the steel wire tube 3. The steel spike 42 can be nailed into the inside of the slope to increase the adhesion between the steel wire tube and the rock layer inside the slope.
[0037] like Figure 1 As shown, the upper slope of the slope body 1 is a fully weathered slope area, in which a first steel wire tube 31 and a first pointed steel tube 21 with a longer length are used for anchoring, and the lower slope of the slope body 1 is a strongly weathered slope area, in which a second steel wire tube 32 and a second pointed steel tube 22 with a shorter length are used for anchoring.
[0038] The implementation process of this utility model is as follows:
[0039] First, drilling is performed on the fully weathered slope. In this embodiment, the drilling depth in the fully weathered slope area is 1 meter, and the drilling depth in the strongly weathered slope area is 0.5 meter. The drilling direction is generally perpendicular to the slope direction, and can also be adjusted to 45° upward or 45° downward according to the on-site slope conditions.
[0040] The steel wire tube 3 with the steel thorn structure 4 inside is placed into the drilled hole, wherein the first steel wire tube 31 is placed into the hole with a depth of 1 meter, and the second steel wire tube 32 is placed into the hole with a depth of 0.5 meter, and then the first pointed steel tube 21 and the second pointed steel tube 22 are respectively driven into the first steel wire tube 31 and the second steel wire tube 32. In this process, the steel thorn structure 4 in the steel wire tube 3 is pushed out to the outside of the steel wire tube 3 by the force of the pointed steel tube 2, and the steel thorns 42 are nailed into the hole wall outside the steel wire tube 3.
[0041] Concrete is poured into one end of the opening of the pointed steel pipe 2, and the concrete flows out through the grouting holes 23 on the surface of the pointed steel pipe 2. The steel wire pipe 3 is a mesh pipe structure woven with steel wires, so the concrete flows through the steel wire pipe 3 and enters the drilled hole to fill the pores. After the concrete solidifies, the pointed steel pipe 2, the steel wire pipe 3, the steel thorn structure 4 and the hole are more tightly combined.
[0042] Finally, concrete mortar is sprayed on the slope surface to form a mortar layer 6, and the top of the slope is covered with original vegetation supplemented with lawn to form an anti-seepage layer 7.
