Geotextile Bag Introduction:
Geotextile bags are continuous (or individual) bag-like 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, introduced and researched in our country in the late 1970s. Molded concrete is formed 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 hanger ropes (polymers such as nylon, etc.) inside the bags. After the concrete or cement mortar sets, it forms a board-like or other structural shape with certain strength, meeting the needs of engineering projects. As a new type of building material, geotextile bags are widely used in protective projects such as river, riverbank, lake, sea embankments, shore protection, harbors, docks, etc.
Features include:
(1) Geotextile bags construction utilizes a one-time sprinkling molding process, making it simple and quick to construct.
(2) Geotextile bags are adaptable to various complex terrains, particularly for deep-water revetments and bottom protection where no embankment filling is required. They can be directly constructed underwater with high mechanization, offering 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 and accelerating the curing speed of concrete, thereby enhancing its compressive strength.
Rectangular formwork fabric has no filtration points on the surface, allowing for the filling of concrete or mortar according to construction techniques. After filling and shaping, it features even surfaces with peaks and valleys, resulting in an aesthetically pleasing appearance. The non-filtration point type formwork is a four-layer structure with double-layered fabric, where the second and third layers form cross-ribbing. The filling and shaping result in the desired thickness, offering high compressive strength of the cured body and an attractive shape. This product has a wide range of applications and is one of the most widely used formwork types currently. It is generally suitable for projects such as dam protection, embankment protection, river channel protection, reservoir bank protection, etc.
The manufacturing process for circular mold bags is quite complex, suitable for projects with thinner concrete filling thicknesses, such as riverway revetments and beach protection.
The filling material inside the hinge bag is mainly mortar, and in special cases, concrete can be适量injected upon the design unit's approval. The blocks are secured with ropes of varying strengths both longitudinally and laterally, threaded through the center of the blocks, ensuring they are firmly interlocked. This allows for drainage while also enabling the blocks to freely settle or shift downward after brushing or subsidence of the foundation. This product is suitable for riverbeds, slope footings, and bend areas of rivers, serving as a protective measure against erosion.
The filling material inside the grass planting bags is typically mortar. This product is woven into two types: character and non-character patterns. 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 mortar solid. Trees, flowers, and grass can be planted inside the frame for beautifying slopes; it is also a novel material for residential areas.
