Problems solved by technology

[0007] When the existing ecological bag slope protection system is constructed, the three-layer ecological bag stacking method is generally used, such as figure 2 As shown, although the effect is very good, the disadvantage is that the amount of ecological bags is large, which leads to high construction costs and the problem of still occupying a large area
[0008] At the same time, when the existing ecological bags are stacked, in order to ensure that the ecological bags can be firmly connected without excessive displacement, an ecological bag connector is used between each layer of ecological bags to puncture the skin of the ecological bag for connection. Connectors generally have sharp corners, which can easily injure people walking or working on the slope in the later stage. Therefore, the slope protection system formed in this way will never allow tourists to enter in the later stage, making the slope a "Green land that cannot be approached" affects the experience of use

Embodiment 1

[0029] Such as image 3 , 4 As shown, the ecological bag ecological slope protection system of the present embodiment includes dislocation along the slope 5 surface layer by layer (dislocation is the seam between the ecological bag 3 in the upper and lower floors is staggered, as Figure 4 As shown, the seam of two adjacent ecological bags 3 on the upper layer is opposite to the middle part of the lower ecological bag 3) stacked ecological bags 3, the long side of the ecological bag 3 faces the slope 5, and the long side of the other side faces outwards, adjacent to the same layer The 3 ends of the eco bag are opposite, such as Figure 4 As shown, the ecological bag 3 is filled with plant growth substrates, the bottom of the slope 5 is provided with a slope protection presser foot 2, and the slope protection presser foot 2 is offset against the outer side of the ecological bag 3 at the bottom of the slope 5 surface, and the outer side of the ecological bag 3 is also covered w...

Embodiment 2

[0043] Embodiment 2 is a construction method of the above-mentioned ecological bag ecological slope protection system, involving the attached image 3 , 4 , 5-1, 5-2, 5-3, 5-4, specifically including the following steps:

[0044] 1) Place the slope protection presser foot 2 at the bottom of the slope, spread the lower end of the geogrid 7 of the first layer of ecological bags 3 on the bottom of the slope, and place the first layer of ecological bags 3 on it, pay attention to the left and right adjacent The sides of the geogrid 7 are overlapped by more than 0.1m, the geogrid 7 and the ecological bag 3 are arranged in a staggered peak, and the sides of the two adjacent geogrids 7 are overlapped in the middle of the first layer of ecological bag 3 , the outside of the first layer of ecological bag 3 is offset against the inner side of slope protection presser foot 2; backfill the soil inside the first layer of ecological bag 3 until the upper surface of the first layer of ecolog...

Abstract

The invention discloses an ecological bag ecological slope protection system and a construction method thereof. The ecological bag ecological slope protection system comprises ecological bags staggered and stacked layer upon layer along the surface of a slope, and only one layer of ecological bags is arranged in the horizontal direction. The ecological bag ecological slope protection system further comprises geogrids. After one end of each geogrid is wound around the corresponding ecological bags, the two ends of the geogrid are anchored in the slope together. The length-width ratio of the ecological bags is 10 or above. The width of the parts, in the length direction of the ecological bags, of the geogrids exceeds the length of the ecological bags by 0.2 m or above. The sides of every two left-right adjacent geogrids are in lap joint in the middle of the corresponding ecological bags, and the lap width of the sides of every two left-right adjacent geogrids is 0.1 m or above. According to the ecological bag ecological slope protection system, the usage quantity of the ecological bags can be reduced, the construction cost can be reduced, and the occupied area of the slope protection system can be reduced.

Description

technical field [0001] The invention relates to the technical field of ecological bag slope protection. Background technique [0002] Slope protection is a general term for all kinds of paving and planting on the slope to prevent the slope from being affected by erosion or weathering. Traditional slope protection measures mainly use gray projects such as stone masonry or shotcrete, which will lead to irrecoverable vegetation on the slope, damage the ecological environment, and affect people's use experience. In recent years, with the enhancement of people's environmental awareness and economic strength, ecological slope protection technology has been gradually applied to municipal engineering construction. [0003] Common ecological slope protection is mainly divided into two categories, one is landfill plant slope protection, and the other is ecological bag slope protection. [0004] figure 1 It is a sectional view of common landfill plant slope protection, such as figu...
