Problems solved by technology
The advantages of turf ecological slope protection are low cost and wide sources, and it can be used for landscape design in the waterfront area while fixing soil and sand; the disadvantage is that the plants themselves have weak anti-scouring ability, because the grass roots themselves cannot withstand long-term submersion. As a result, the water and soil conservation effect is weak when the water flow velocity is fast, and it is often used for bank slope protection in areas above the normal water level

Embodiment 1
[0049] This embodiment discloses a grass-planting double-mode bag ecological concrete slope protection, and the specific cross-sectional structure schematic diagram is as follows figure 1 shown.
[0050] On the surface of the slope, the filter layer 5 (optional layer), the lower mold bag structure layer (the first mold bag structure layer), and the upper mold bag structure layer (the second mold bag structure layer) are successively laid from bottom to top.
[0051] In this embodiment, the material of the reverse filter layer 5 is polyester long fiber non-woven fabric.
[0052] In this embodiment, the lower mold bag structure layer adopts the geotechnical mold bag 3; after the geotechnical mold bag 3 is laid, the overlapping parts of the adjacent mold bags are connected by sewing, and nylon thread or resin material can be used as the suture material , materials and technical parameters refer to the relevant specifications of the mold bag concrete; the geotechnical mold bag 3 ...
Embodiment 2
[0059] This embodiment discloses a construction method for planting grass-type double-mode bag ecological concrete slope protection. The specific construction process is as follows: Figure 4 shown, including the following steps:
[0060] (1) Construction preparation
[0061] According to the actual situation, concrete pump trucks or ground pumps can be used for pumping construction. When ground pumps are used for concrete mixing on site, an on-site mixing station is required; if concrete pump trucks are used for pumping, concrete tank trucks are generally required for transportation. Preparation of material plan etc.
[0062] (2) Measurement and setting-out
[0063] According to the requirements of the design drawings, stake out the shoulder, toe line and sideline of the bagged sand slope, and mark the elevation points on the steel rods or bamboo poles at the corresponding positions, so as to make full preparations for the slope .
[0064] (3) Bag sand slope

Abstract
The invention discloses an ecological slope protection structure. The ecological slope protection structure comprises a first mold bag structure layer and a second mold bag structure layer arranged onthe slope face, the second mold bag structure layer is located above the first mold bag structure layer in the direction perpendicular to the slope face, the second mold bag structure layer and the first mold bag structure layer are connected into a whole body, the first mold bag structure layer is of a structure formed by a civil engineering model bag filled with porous ecological concrete, thesecond mold bag structure layer is of a seed-nutriment-soil sack structure including plant growth base materials, a vegetation cloth layer and pressing strips, the vegetation cloth layer is laid on the surface of the plant growth base material, the pressing strips are fixed to the surface of the vegetation cloth layer, the vegetation cloth layer is formed by connecting multiple frames of vegetation cloth, and the pressing strips are used for keeping stability of the second mold bag structure layer. The invention further discloses a construction method of the ecological slope protection structure. The grass planting type dual-mold-bag concrete slope protection has the beneficial effects of being good in stability, wide in application face, safe, reliable, high in anti-scouring performance,good in ecological performance, and simple and rapid in construction.
Description
technical field [0001] The invention relates to the field of slope protection engineering, in particular to an ecological slope protection structure and a construction method thereof. Background technique [0002] Slope protection is a common building structure in water conservancy projects, which can drain water and reduce soil erosion. The protection of embankments and slopes of reservoirs and rivers has attracted more and more attention. Traditional slope protection uses hard materials such as cement, asphalt, and concrete as the main building materials. ecological function. Natural vegetation or plant slope protection has good ecological performance, but poor slope stability and poor erosion resistance. At present, mold bag concrete slope protection, vegetation-type ecological concrete slope protection, and turf slope protection are the most widely used slope protection methods. [0003] The mold bag concrete slope protection technology uses a geotextile fabric bag ma...
