Concrete Geotextile Mattress are widely used in slope protection and have many significant advantages.
Construction advantages
Construction is simple and fast: Geobag construction adopts a one-time spraying molding method, and the construction process is simple, which can greatly shorten the construction time and speed up the construction progress. For example, in river slope protection projects, compared with traditional construction methods, geobag slope protection can significantly improve construction efficiency and reduce construction period.
Adapt to complex terrain: It can adapt to various complex terrains, especially in deep-water revetment, bottom protection and other projects. In these projects, geobags can be directly constructed underwater without the need to build cofferdams, which reduces the difficulty and cost of construction. At the same time, the slope protection surface area is large, the integrity is strong, the stability is good, and the service life is long.
Structural advantages
Good water permeability: Geobags have a certain water permeability. When concrete or cement mortar is poured in, excess water will seep out through the gaps in the fabric, quickly reducing the water-cement ratio, accelerating the solidification of concrete, and increasing the compressive strength of concrete. This helps to improve the stability and durability of the slope protection structure.
Control filling thickness: The upper and lower layers of the mold bag are connected by a certain length of nylon rope, which can accurately control the thickness of the filling and ensure the quality and uniformity of the slope protection structure.
Cost and maintenance advantages
Reduce project cost: Compared with the traditional method of pouring concrete on site or laying prefabricated blocks, geobag slope protection technology has the advantages of rapid construction, convenience, safety and economy. According to the experience of Jilin Province, the use of mold bags saves more than one-third of investment compared with dry block stone slope protection.
Low maintenance cost in the later stage: The geobag slope protection structure has strong integrity and good stability, and requires less maintenance during operation, thereby reducing the later maintenance cost and improving the comprehensive benefits of the slope protection project.
Ecological advantages
Conducive to ecological restoration: Geobag slope protection can provide a good shelter for animals and plants, which is conducive to the restoration of the ecological and landscape environment around the river. Unlike some hard slope protection structures, it does not cause great damage to the ecological environment, but can integrate with the natural environment to promote the balance and development of the ecosystem.
