The present invention will be described in further detail with reference to the following examples and drawings, but the present invention is not limited thereto.

The first embodiment is as follows:

as shown in fig. 1-5, this embodiment discloses a rock slope ecological protection structure, includes: base 1, stock 2, lattice beam 3, ecological box, plant and grow bag 6.

A rock slope ecological protection structure is characterized in that a base 1 bears vertical loads and impact forces transmitted by an upper ecological box 4, soil bodies in the ecological box, hillside rockfall and the like, and the size of the base 1 needs to meet the stability of the whole structure. The base 1 is made of cast-in-place C25 concrete, the thickness is 1-2m, the width is 2-3m, the front end of the bottom is provided with an anti-skid wall 101, the depth of the wall is 0.5-1m, and the thickness of the wall is 0.5-1 m. To increase the resistance to sliding, the bottom is set to a 1:20 counter slope 102. The surface water of the rock slope is difficult to seep, the runoff coefficient is large, the slope is steep, the slope runoff speed is large, and the scouring force is strong, so that the front foot of the base 1 is provided with a grouted stone 103 drainage ditch 104 for preventing scouring, the width of the drainage ditch 104 is 0.5-1m, and the depth is 0.5-1 m.

Furthermore, the section of the rock slope lattice beam 3 is 0.5mx0.5m, expansion joints are arranged every 20m, and the width of the joint is 2 cm. The anchor rod 2 is a phi 18 pressure grouting anchor rod, the incidence angles are all 30 degrees, the length of the anchor rod is 4m, and the distance is 5mx5 m.

Preferably, the anchor rod is drilled by an air gun, and the drilling direction is vertical to the main structural surface of the rock stratum. The diameter of the anchor rod hole is 15mm larger than the diameter of the rod body, and the allowable deviation of the anchor rod hole depth is +/-50 mm. And (3) pouring 204 cement mortar after checking and accepting the hole depth and the hole diameter, wherein the pressure of a grouting hole opening is controlled to be 0.4-0.6 MPa. After grouting, the anchor rod body, namely the anchor bar 203 is inserted, the length of the anchor bar in the anchor bar insertion hole is not less than 95% of the designed length, and cement mortar 204 flows out of the hole opening.
