Detailed Description
The invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1 to 3, a soft and hard combined earth and stone pile blocking and protecting structure can be applied to a mountain road, and a main body of the structure comprises a concrete retaining wall 1 and a flexible protective net 2. The concrete retaining wall 1 mainly prevents the pile from sliding downwards, and the flexible protective net 2 mainly prevents flying stones and stones from rolling off.
The concrete retaining wall 1 is arranged above a toe road for 10 to 20 m (along the length of the slope), the flexible protective net 2 is arranged above the concrete retaining wall for 2 to 5 m (along the length of the slope), the concrete retaining wall and the flexible protective net are arranged independently, the flexible protective net forms a first blocking protection, the concrete retaining wall forms a second blocking protection, and the concrete arrangement can be adjusted by combining with the actual terrain condition.
The concrete retaining wall 1 is of a C20 reinforced concrete structure, and the reinforcing steel bars are second-level reinforcing steel bars. When the pile has a tendency to slide down, the concrete retaining wall 1 can stop this tendency by virtue of its gravity in a manner similar to a gravity dam retaining water.
The concrete retaining wall 1 is built on a foundation 11, a bottom plate 14 is arranged below the concrete retaining wall for facilitating construction, a drain pipe 13 is arranged inside the concrete retaining wall for draining water, one end of the drain pipe 13, which is positioned in a side slope, is provided with geotextile 12 for filtering and draining water, and a pedestrian path 15 is arranged beside the concrete retaining wall.
The flexible protective net 2 is a passive protective net. The flexible protective net 2 comprises a steel wire rope rhombic net 6, an upper supporting rope 7 and a lower supporting rope 8 are respectively arranged on the upper edge and the lower edge of the steel wire rope rhombic net 6, steel columns 5 used for erecting the steel wire rope rhombic net 6 are arranged on the two sides and the middle of the steel wire rope rhombic net 6, and the steel columns 5 are arranged on a concrete foundation 4. The concrete foundation can be excavated to the bedrock and reinforced by the anchor rod, and the anchor rod adopts a second-level steel bar.
When the flying stones fall off, the steel wire rope diamond-shaped net 6 can intercept the flying stones.
As shown in fig. 3, the grid net 9 is located in the middle of the wire rope diamond net 6, in the present embodiment, the grid net 9 is embedded in the wire rope diamond net 6 and is integrated with the wire rope diamond net 6, but in other embodiments, the grid net 9 may be attached to the wire rope diamond net 6. The grid net 9 is smaller than the wire rope rhombic net 6 and is in a tight state to tension the wire rope rhombic net, so that the whole side slope can be continuously supported, and the active protection function is realized.
A plurality of pressure reducing rings 10 are arranged on the upper supporting rope 7 and the lower supporting rope 8. The pressure reducing ring 10 is mainly used for buffering and reducing kinetic energy generated by sudden stone impact.
The steel columns 5 at the two sides of the wire rope diamond-shaped net 6 are fixed with the concrete foundation 4 adjacent to the steel columns through the side-pulling anchor ropes 3 so as to effectively fix the wire rope diamond-shaped net 6.
The above-mentioned embodiments are only for explaining the preferred embodiments of the present invention, and not for limiting the present invention, and any modifications, equivalent replacements, improvements, etc. made by the present invention fall within the protection scope of the present invention within the spirit and the protection scope of the claims.
