Geotextile Bag Introduction:
Geotextile bags are continuous (or separate) bag-like products made from a double-layered fiber composite material. The application of geosynthetic materials in engineering is a new technology that has developed over the past two decades, introduced and developed in our country in the late 1970s. Molded concrete is achieved 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 hanger bags and cables (polymers like nylon, etc.) inside. After solidification, the concrete or cement mortar forms a structural board or other shape with certain strength, meeting the requirements of engineering projects. As a new type of building material, geotextile bags can be widely used in protective projects such as river, riverbank, lake, sea embankments, shore protection, harbors, docks, etc.
Boasts the following advantages:
(1) Geotextile bags construction employs a single spray molding process, making it simple and quick to install.
(2) Geotextile bags are adaptable to various complex terrains, particularly in deep-water revetments and base protection where no embankment filling is required. They can be directly installed underwater, featuring high mechanization, a large protected slope area, strong integrity, good stability, and a long service life.
(3) Geotextile bags possess certain permeability. After concrete or cement mortar is poured in, excess water seeps out through the fabric gaps, rapidly reducing the water-cement ratio, accelerating the concrete setting speed, and enhancing the concrete's compressive strength.
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 a beautiful finish. 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 mesh. The filled and shaped product achieves the designed thickness, exhibiting high compressive strength of the solidified body and an aesthetically pleasing shape. 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 water storage pools.
The manufacturing process for the circular mold bags is relatively complex and is suitable for projects with thin concrete filling thickness, such as river channel revetments and beach protection.
The filling material inside the hinge mold bag is mainly mortar, and in special cases, concrete can be适量 filled with the approval of the design unit. The blocks are secured with ropes of different strengths both longitudinally and laterally, threaded through the center of the blocks. This ensures that the blocks are interlocked and can drain while also allowing for downward settlement or displacement after brushing or foundation settlement. This product is suitable for riverbeds and slope feet, as well as river bends, serving as a protective measure against erosion.
The filling material for the grass planting bags is usually mortar. The product is woven into two types: with and without a checkered pattern. The former has a complex structure with the grid size generally ranging from 22 to 30 cm. The thickness around the grid is less than 15 cm, forming an elliptical solidified mortar section. Trees, flowers, and grass can be planted within the grid to beautify slopes; it is also a novel material for residential areas.
