Ecological bags are a high-strength ecological synthetic material that is resistant to ultraviolet rays, freezing and thawing, as well as acidic and alkaline substances. They represent a new type of high-tech special material, featuring high strength UV resistance, acid and alkali resistance, corrosion resistance, and can remain non-degradable for over 50 years, truly achieving zero pollution. They are primarily used for constructing flexible ecological slopes. The bags are moisture-resistant, do not absorb water, and water will not damage the bags or cause deformation. They are also insoluble in polluted liquids, making them an excellent tool for ecological protection and highly practical.

Define Concepts

Bags made from double-sided needle-punched nonwoven fabric, which is processed from raw materials such as polypropylene (PP) or polyester fiber (PET). These bags undergo strict selection for indicators such as thickness, unit weight, physical and mechanical properties, appearance, fiber type, stress mode, direction, geometric dimensions, water permeability, and equivalent pore size for plant growth. They feature UV resistance, anti-aging, non-toxicity, non-flammability, and the characteristic of not extending cracks. Mainly used for constructing flexible ecological slopes. The ecological bag slope protection greening is one of the important construction methods for restoring barren mountains, mining areas, highway slope greening, riverbank slope protection, and river restoration.

The XinGeng Eco-Bags boast excellent physical and chemical properties. This specially formulated material can withstand UV degradation, is unaffected by chemical substances in the soil, and does not undergo quality change or rot. It is non-degradable and resistant to pest infestation, has anti-aging properties, is non-toxic, and can withstand erosion from acids, alkalis, salts, and microbial decomposition. It allows water to pass through but not soil, being plant-friendly and suitable for vegetation greening. It also has the following environmental versatility advantages:

Functionality Features

Moisture-resistant

Eco-bags are made from materials that do not absorb moisture. When moisture is present, it does not damage the bag, and the bag does not deform or dissolve in contaminated liquids.

Chemical Resistance (PH)

Extensive research and testing have shown that eco-bags exhibit strong resistance to certain concentrations of acidic and alkaline chemicals, making them suitable for most solid waste and heavily polluted sites.

Anti-biodegradable and animal-resistant

Eco-bags are made from special formula materials that do not support, absorb, or aid in the growth of fungi. They do not rot, mildew, or degrade. Eco-bags are not digestible by insects or related animals and are not food for rodents, termites, woodworms, beetles, silverfish, and other chewing insects.

High-UV-resistant polymer

Eco-bags can withstand high temperatures of up to 150 degrees Celsius without melting and can endure low temperatures down to -40 degrees Celsius.

Ultraviolet (UV) Protection

Eco-bags contain carbon ink and other UV-resistant ingredients.

Here's an example to illustrate with equivalent aperture:

One: Hole diameter too large (bag body, material too thin)

A. It hinders vegetation growth and root extension, severely affecting the structural stability of flexible slopes.

C. The increased hydrostatic pressure on the slope due to this would cause the slope to collapse.

Advantages and Features

In slope engineering, this new material can completely replace stone and cement, significantly reducing engineering costs. The treated slope surface is capable of being vegetation-covered, achieving a green landscaping effect and forming a natural ecological slope. It possesses a filtering function that allows water permeation but prevents soil erosion, providing strong protection and stability against soil loss, localized mud/stone flows, and slope collapses, making it a highly stable natural slope.

Specification Parameters

Design Specifications

Flat Size Range: (Customizable according to design and engineering requirements)

Fabric weight range: Broad range, commonly including 100g, 125g, 150g, etc.

Fabric Tensile Strength: ≥4.5 kN/m

Fabric elongation at break: ≥40%

Volume calculation formula for soil in ecological bags after shaping:

Length = Eco Bag Length - (12~15) cm

Width = 0.7 x Eco Bag Width

Height = 0.4 * Eco Bag height

An example bag with an outer diameter of 810mm x 430mm will be approximately 65cm in length, 30cm in width, and 15cm in height after being filled with soil (The specifications of the ecological bags and their formed dimensions after being filled with soil can be designed according to actual requirements. Allowable deviation is up to 2%).

Benchmark reference

Currently, there are no national or industry standards for eco-bags in our country. The technical parameters refer to the Chinese National Standard GB/T 17639-2008 for Geotextiles - Staple Spunbonded and Needle-punched Nonwoven Geotextiles.

Development Timeline

Bags made from double-bonded needle-punched non-woven fabric, which is produced using raw materials of polypropylene (PP) or polyester fiber (PET).

Manufacturing Requirements

Under comprehensive consideration of the requirements from various disciplines such as material mechanics, hydraulics, biology, and botany, strict selection has been made on the thickness, unit mass, physical and mechanical properties, shape, fiber type, load-bearing method, direction, geometric dimensions, and water permeability of the eco-bags, as well as the equivalent aperture to meet plant growth. They feature UV resistance, aging resistance, non-toxicity, non-flammability, and crack non-progression, truly achieving zero pollution.

Eco-bags feature targeted water-permeable and soil-impermeable filtration, preventing the loss of filling materials (soil and nutrients) while allowing normal water exchange within the soil. This ensures effective retention and timely replenishment of water essential for plant growth, making them highly friendly to plants and enabling them to grow freely through the bags. The root systems penetrate into the engineered base soil, where numerous anchor rods reinforce the stability between the bags and the main structure, becoming increasingly firm over time. This further achieves the goal of constructing stable slopes, significantly reducing maintenance costs.

Eco-bags with special functional requirements, where the design of their functional features is a necessary condition for the stability of flexible slope structures.
