High quality non woven geotextile, especially referring to short fiber non woven needle punched geotextile, is the most cost effective and extensively used geotextile fabric to ensure optimized performance and design life of soil or granular layers in a range of civil, coastal and environmental engineering projects. Needle punched geotextile fabric is felt-like and very flexible, having a fibrous network with distinctive pores, which makes them suitable for applications in filtration, drainage, separation and protection applications.  Staple fibre needle punched geotextile is often manufactured from short polypropylene or polyester fibers.  Polypropylene has good chemical stability and cost/weight ratio, but polyester offers good chemical resistance, high creep strength and tensile strength.

Case Study

  • Location : Peru
  • Product(s) : Nonwoven Geotextile
  • Application : Mining Project

Issue

In mining projects, the tailings contain toxic substances or radioactive substances or heavy metal ions, which will seriously pollute the groundwater source, and seepage prevention treatment must be done.

Solution

Staple fibre needle punched geotextile is made from 100% virgin staple polypropylene fibers that are tangled and interlocked with each other by needle-punching process.  This the kind of short fiber high quality non woven geotextile is robust, durable, permeable and resist to deformation. BPM short fiber nonwoven geotextile fabric is widely used to increase ground support and soil stabilization in a given location, it has the characteristics of high tensile strength, high elongation rate, excellent UV stabilization, excellent filtration and good abrasion resistance, etc. It is widely used for filtration, separation, protection, drainage applications in civil environmental engineering and construction projects.

As one of the important geosynthetic solutions for Chile customer mining project, this mining project required 230,000 square meters PP Short fiber nonwoven geotextile for mining protection and reinforcement. BPM brand high quality non woven geotextile include filament non woven geotextile, short fiber needle punched geotextile fabric, etc. We also produce woven geotextiles including polypropylene woven geotextile and pet woven geotextile fabric. After detailed communication, our customer ordered PP Short fiber nonwoven geotextile for this mining project. Because PP nonwovens not only have high tear strength and tensile strength, but also have high acid and alkali resistance. It is very suitable for mining engineering.

Functions of High Quality Non Woven Geotextile for Mining Project in Peru

1. Isolation. Use polyester staple fiber needling method to separate building materials (such as soil particles, soil, soil and concrete, etc.) to disperse the corresponding physical personality (such as size, range, saturation and density, etc.). Ensure that there is no loss or mixing between two or more materials, ensure the original shape and performance of raw materials, and make the structure more superfrequency.

2. Filtration (inverted filtration). Polyester staple fiber needled geotextile has good permeability and permeability, so that the liquid flows through, and can effectively guide soil particles, sand dust, small stones, etc., so as to ensure the stability of normal projects.

3. Drainage. Polyester staple fiber needled geotextile has excellent water conductivity, which can create a water conduit inside the soil particles, and can discharge the remaining water and oxygen in it.

4. Reinforcement. The use of geotextiles expands the toughness and impact resistance of soil, improves the stability of building structures, and improves the quality of soil.

5: Protection. When water rushes into the soil, it can effectively spread, interact or decompose the concentrated stress, resist the impact damage of the soil and protect the land.

6: Anti penetration.  The composite impermeable material formed by the fusion of geomembrane plays the role of stab prevention. Excellent tensile strength. Good permeability. High temperature resistance. Anti freezing. Anti aging. Corrosion resistance. Worm proof. Polyester staple fiber needled geotextile is a kind of commonly used geosynthetics. Reinforce the railway subgrade. Maintenance of highway pavement. Gymnasium. Protection of dams. Isolation of hydraulic structures. Suidong. Coastal beach. Reclamation. Environmental protection, etc.

Geotextile construction precautions

Do not drag or drag the geotextile during transportation to avoid stabbing by sharp objects.

  1. Before construction, the substrate should be cleaned. If conditions permit, it can be washed with water to ensure that the substrate is free of any impurities. If there are cracks in the base, it can be repaired with asphalt. Otherwise, the effect of pavement and final use will be affected in the later stage.
  2. When paving, the material should be straightened as much as possible, and when paving, it should be as flat as possible, because in this way, it can be as close to the base as possible. If there is oil on the bottom, you can roll it with a roller brush, so that it will fit better, and then sprinkle some melon seeds or coarse sand on it.
  3. When paving, it is necessary to ensure that the woven fabric is dry, because the effect will be greatly reduced after the rain is wet. If it is wet, it should be paved after it is completely dry. At the same time, smoking is not allowed during laying, which will be more dangerous. When just finished, don’t walk on the surface, don’t move tools, and don’t keep heavy objects on it.
  4. There should be some overlap at the lap joint, and the effect will be better after layer by layer pavement. The joint can be welded, so the stability is better. In addition, pay attention to the slope and the position of the corner, where the splicing length can be shortened to avoid wrinkles.

Construction method

  1. It should extend from the bottom to the high position, and should not be pulled too tightly. There should be a half of the remaining width for local sinking and stretching. Considering the actual situation of the project, the slope is paved from top to bottom;
  2. The longitudinal joints of two adjacent frames shall not be on the same horizontal line, and shall be staggered by more than 1m;
  3. The longitudinal joint should be more than 1 or 50m away from the dam toe and bend, and should be set on the plane;
  4. Slope first and then the bottom of the site; What are the characteristics and functions of geotextiles used in construction;
  5. When laying the slope, the film spreading direction should be basically parallel to the slope line.
