Advantages of Lvba Slope System
1, environmental protection, beautiful sound effect, and perfect integration with natural ecological environment. Construction waste and construction noise will not be generated during construction.
2. Vegetation selection can be diversified, which is conducive to the rapid restoration of the ecosystem and the rapid restoration of the slope environment to the natural state.
3. It is a triangular internal friction locking structure, which is stressed as a whole, has scientific stability, absorbs energy, buffers external impact, and its seismic performance is incomparable with traditional slopes.
4. The structural plane is combined with the slope through the root system with developed vegetation, so that the artificial slope and the original natural slope will not be separated and collapsed. Moreover, with the passage of time, the increasingly vigorous vegetation roots make the slope structure more stable and firm, which is a natural and living permanent ecological project.
5. The structure is simple. Under the guidance of construction guidance and technicians, both male and female laborers without any technical experience in slope schemes can participate in the construction, thus solving the employment problem of a large number of surplus laborers.
6. The general foundation does not need engineering treatment, and the adaptability to uneven settlement is one of the characteristics of this system. At the same time, the structure will not produce temperature stress, and there is no need to set temperature joints.
7. The construction is fast and convenient, without "three links and one leveling", and the standard materials are portable.
8. The traditional rigid structure can't solve the engineering problems of freeze-thaw and expansive soil. ......
A. When the water content in the back fill of the traditional retaining wall in the freeze-thaw area is below zero, the volume of ice will become 1. 1 1 times, which will generate great additional stress on the back of the retaining wall and cause local or overall damage to the structure; At the same time, the water in the structural joints also freezes and expands at the same time, causing local damage and cracking. The flexible retaining wall has no structural joints and will not cause local damage. At the same time, the water in the soil in the ecological bag and the water in the backfill soil will become a whole when it freezes, forming an infinite whole structure, which will not cause damage.

B) The volume expansion of the stirred expansive soil in the expansive soil area causes great additional stress on the back of the retaining wall, resulting in local or overall structural damage; Soft and flexible structure can adapt to this deformation and extrusion; At the same time, the local concentrated expansion force can be transformed into uniform stress, which has a good effect of combining rigidity with flexibility. Keep the structure stable.
C. In the water level fluctuation zone of the reservoir area, under the water level change and wave erosion, the root soil of vegetation is hollowed out, the surface is immediately deserted, and the long liquefied zone of soil is put into the bottom of the reservoir. The bag with special function in flexible structure can prevent liquefaction and loss, effectively prevent soil and nutrient loss, and let vegetation take root and grow. At the same time, it can fill and supplement the local gaps on the slope in time, cut off the passage of water flow, and the roots of vegetation can be inserted and anchored. So as to form a stable ecological slope.
D. adopt greenbay? As a flexible retaining wall structure, the three-dimensional drainage flexible ecological slope engineering system saves 60%-30% compared with the traditional masonry retaining wall structure (see the figure below). In the northern freeze-thaw area (gravity retaining wall foundation depth (1.5-2.0m), the cost will be saved by more than 10%. On the soft foundation near the water, the project cost can be greatly reduced.
9. A. When the moisture in the backfill soil of the traditional retaining wall in the freeze-thaw area is below zero, the volume of ice will become 1. 1 1 times, which will cause great additional stress on the back of the retaining wall and cause local or overall damage to the structure; At the same time, the water in the structural joints also freezes and expands at the same time, causing local damage and cracking. The flexible retaining wall has no structural joints and will not cause local damage. At the same time, the water in the soil in the ecological bag and the water in the backfill soil will become a whole when it freezes, forming an infinite whole structure, which will not cause damage.

9. A benign ecological vegetation system can be formed, and trees, shrubs, vines, flowers and grasses are organically combined, so that the vegetation is not easy to degrade and the later maintenance cost is greatly reduced.
10. The special function design of the main engineering components-the green bully ecological bag and the three-dimensional drainage coupling buckle basically does not produce seepage pressure on the slope structure, which makes the slope structure more natural and stable.
1 1. In the process of filling soil, elements and nutrients lacking in soil can be reasonably and accurately supplemented, which is more conducive to the growth of vegetation.
12.0-90 degrees can be used to build slopes with any slope angle, thus saving land for engineering construction.
13. When this system is adopted, the structure can be combined with the traditional civil engineering structure with good matching and combination.
14 is an advanced slope structure form, which makes the structure stable and soil and water conservation and ecological vegetation can be realized simultaneously.
15. Ecological restoration of hard slopes or rocky slopes can provide a soil environment with sufficient thickness for vegetation growth.
16, the construction safety is greatly improved, and there is no possibility of injuries caused by rigid objects.
Lvba 3D drainage flexible ecological slope engineering system is an engineering patent system, which uses environmentally friendly soft materials instead of traditional hard materials such as steel bars, cement and stone with high energy consumption and high pollution to build slopes.
Among them, the green bully ecological bag is an important part of the green bully three-dimensional drainage flexible ecological slope engineering system. Green bully ecological bag provides an ideal planting plot for green vegetation. The green bully ecological bag has a filtering function, which can prevent particles from penetrating when water is allowed to pass through. Green bully ecological bag is permeable to water and impermeable to soil, which is the key feature of soil and water conservation.
Green bully ecological bag has the characteristics of anti-ultraviolet, anti-aging, non-toxic, no combustion-supporting, no crack propagation, never degradation, complete recycling and truly zero pollution;
Lvba ecological bag has targeted filtration function of water-permeable and impermeable soil, which can not only prevent the loss of fillers in the ecological bag, but also realize the normal exchange of water in the soil, thus reducing the hydrostatic pressure of the slope. At the same time, the green bully ecological bag is impermeable, and it also maintains the medium in which water, soil and vegetation can survive.
Green bully ecological bag is soft and convenient to construct.
Green bully ecological bag is mainly used to build flexible green ecological slope.
