At the same time, it is also necessary to arrange passive protection nets to form surface protection for the protection area above the water intercepting ditches, so as to prevent the falling of collapsed rock masses and play a role in slope protection. For steep rocky slopes, the construction of both water intercepting ditches and passive protection nets is relatively difficult, the on-site trenching difficulty is high, and anchoring facilities need to be arranged, resulting in a large construction time consumption. Content of the Utility Model

[0003] The purpose of the utility model is to overcome the above-mentioned deficiencies of the prior art and provide a water intercepting and protecting structure for a rocky slope, which can solve the problems that the construction of both water intercepting ditches and passive protection nets on steep rocky slopes is relatively difficult and the on-site trenching difficulty is high.

[0004] To this end, the utility model adopts the following technical solutions:

[0005] A water intercepting and protecting structure for a rocky slope includes a fixed base arranged on one side of the bottom of a steep rocky slope. The fixed base includes a base section fixed base, and a plurality of enlarged section fixed bases are arranged on the side of the base section fixed base away from the steep rocky slope. A water intercepting wall is arranged on the upper surface of the base section fixed base, and a passive protection net structure is connected to the upper surface of each enlarged section fixed base.

[0006] On the basis of adopting the above technical solutions, the utility model can also adopt the following further technical solutions, or use a combination of these further technical solutions:

[0007] The distance between two adjacent enlarged section fixed bases is 5m to 10m.

The structure base is connected with support columns, the upper ends of the support columns are connected with a wire mesh, and the lower parts of the wire mesh are respectively connected with the structure base and the upper part of the water intercepting wall.

[0009] The upper end of the support column is also connected with a tension anchor rope, the end of the tension anchor rope is connected with an anchor rod, and the anchor rod is fixed on the steep rocky slope.

[0010] The height of the anchor rod is higher than the height of the water intercepting wall.

[0011] The said structural foundation is anchored to the fixed base of the enlarged section through anchor bolts for foundation bolts.

[0012] There are at least two rows of mortar anchor bolts arranged in the fixed base of the foundation section. The lower part of the mortar anchor bolts extends into the steep rocky slope. At least one row of the mortar anchor bolts is arranged throughout the water cut-off wall.
