Embodiment 1

[0032] see Figure 1-4 , a slope ecological protective blanket structure, which includes an expanded cement blanket structure, a vegetation concrete structure, a water storage and drainage system, and a fixing system; the expanded cement blanket structure is fixed against the slope surface by a fixing system, and the vegetation concrete The structure is closely attached to the upper surface of the expanded cement blanket structure; the water storage and drainage system is arranged between the top of the slope and the vegetation concrete structure and is used for vegetation irrigation. Through the above-mentioned structure, a kind of ecological protection blanket structure with rapid construction is designed by combining planting concrete and cement blanket. Appropriate slotting on the slope and the arrangement of water-saving facilities and drainage facilities can reduce the amount of accumulated water in the slope in the rainy season and supplement the minimum water consumpti...

Embodiment 2

[0041] The construction method of described slope ecological protection blanket structure, it comprises the following steps:

[0042] Step 1: firstly carry out preliminary observation and assessment to the side slope to be prevented and controlled, for the side slope that does not have serious irregularity in rock-soil layer, first dig horizontal drainage ditches 20 evenly along the slope surface at intervals, then make thin spray layer 7 on the surface of the rock formation, After the initial setting, the thin spray layer 7 is chiseled, so that the thin spray layer 7 is dried and shaped to form a rough hole shape;

[0043] Step 2: Put anchors 8 on the four corners of the evenly divided block of the drainage ditch 20, dig a trough-type water storage pit 17 at the place where the water storage pit needs to be set, and the anchor rod 18 goes deep into the rock formation, and the prefabricated components of the water storage pit 19 is fixed in the rock and soil slope, and its low...

Abstract

The invention provides a slope ecological protection blanket structure and a construction method. The slope ecological protection blanket structure comprises an expansive cement blanket structure, a vegetation concrete structure, a water storage and drainage system and a fixing system. The expansive cement blanket structure, the vegetation concrete structure, the water storage and drainage systemand the fixing system form the whole slope ecological protection blanket structure which can effectively play a role in slope stabilization and water storage and drainage. All accumulated water is slope rainwater, and thus the cost of artificial water application under drought conditions is reduced.

Description

technical field [0001] The invention relates to the technical field of slope protection, in particular to a slope ecological protective blanket structure and a construction method. Background technique [0002] At present, planting concrete technology is commonly used in the reinforcement treatment of steep slopes. This technology mainly uses membrane bags to fix planting concrete on the slope surface for protection, and effectively strengthens the slope through plant growth and concrete hardening. However, under the action of planting concrete technology, the strength of the slope in the long-term dry-wet cycle state during the climate change process may be reduced and damaged. At the same time, the water for plant growth in the dry season cannot be effectively guaranteed. In view of this series of problems, whether the precipitation contacted by the slope can be effectively reduced and the precipitation can be supplied to the growth of plants becomes the key.
