Geotextile Bag Introduction:
Geotextile bags are continuous (or separate)袋状products made from a double-layered polymer fiber composite material. The application of geosynthetic materials in engineering is a new technology that has developed over the past two decades, and was introduced and developed in our country in the late 1970s. Molded concrete is produced by injecting concrete or cement mortar into the bags using a high-pressure pump, with the thickness of the concrete or cement mortar controlled by the length of the suspension wire bags and suspension wires (polymers like nylon, etc.) inside the bag. After the concrete or cement mortar solidifies, it forms a board-like structure or other structures of certain strength, meeting the needs of engineering projects. As a new type of building material, geotextile bags can be widely used in protective projects such as embankment slopes, riverbanks, harbors, and docks.
Boasts the following advantages:
(1) Geotextile bags are constructed using a single-spraying molding process, making the construction simple and fast.
(2) Geotextile bags are adaptable to various complex terrains, particularly in deep-water revetments and foundations where embankment filling is not required. They can be directly constructed underwater, offering high mechanization, a large protected slope area, strong integrity, good stability, and a long service life.
(3) Geotextile bags have a certain permeability. After concrete or cement mortar is poured in, excess water seeps out through the fabric gaps, quickly reducing the water-cement ratio, accelerating the concrete setting speed, and enhancing the compressive strength of the concrete.
Rectangular formwork fabric has no filtration points on the surface, and can be filled with concrete or mortar according to the construction process. After filling and shaping, it features even contours and an aesthetically pleasing appearance. The non-filtration point formwork is a four-layer structure with a double-layer fabric, where the second and third layers form an interlaced reinforcing grid. The filled and shaped product achieves the designed thickness, boasting high compressive strength of the solidified body and an attractive appearance. This product has a wide range of applications and is one of the most widely used formworks currently. It is generally suitable for embankment, slope protection,堤岸, and bottom protection projects such as reservoirs, water conduits, river channels, and reservoirs.
The manufacturing process of the batching bag for round coils is rather complex and is suitable for projects with thinner concrete filling thickness, such as river channel revetments and beach protection.
The filling material for the hinge form bag is mainly mortar, and in special cases, concrete can be适量 filled upon the design unit's approval. The blocks are secured with ropes of different strengths, both longitudinally and transversely, threaded through the center of the blocks. This ensures both drainage and the ability to freely settle or shift downward after brushing or subsidence of the foundation. The product is suitable for riverbeds, slope feet, and river bends, serving as a protective measure against erosion.
The filling material for grass planting bags is typically mortar. The product is available in two types: woven with a "checkered" pattern and without. The former has a complex structure, with the frame size generally ranging between 22-30cm. The thickness around the frame is less than 15cm, and the cross-section forms an elliptical solidified mortar. The frame can be used for planting trees, flowers, and grass, thus beautifying slopes; it is also a novel material for residential areas.
