CASE STUDY
- Location : New Zealand
- Product(s): PET Filament Fabric Geotextile
- Application : Driveway fabric Constrution
Issue
A customer in New Zealand saw an example（case） of our driveway fabric case on Google and wanted the BPM team to come up with a solution that would help prevent ruts and potholes and greatly reduce the need to replace most of the rocky surface of the driveway every few years. Also helps extend the life of asphalt or concrete driveways by reducing cracking.
Solution
PET Filament fabric Geotextile is our recommended fabric for typical residential driveway applications. Some unique job sites or traffic conditions may require the use of heavier stabilizing fabrics. PET Filament Geotextile 200g is a commercial grade construction fabric with high tensile strength.
PET filament geotextile has excellent filtration, isolation, reinforcement and protection, high tensile strength, good permeability, high temperature resistance, freezing resistance, aging resistance and corrosion resistance.
General engineering mainly uses PET filament geotextiles. PET filament geotextiles have many functions such as anti-seepage, reverse filtration, drainage, isolation, reinforcement, protection, sealing, etc. It has anti-seepage effect with conventional masonry and concrete materials In contrast, it has the advantages of low investment, simple construction process, short construction period, good anti-seepage effect, and high channel effective utilization coefficient, and reduces investment and shortens construction period.
International agricultural engineers define PET filament geotextiles as: geotextiles or geosynthetics that exist between soil and pipes, gabions, or retaining walls to enhance water movement and hinder soil movement. The definition of PET filament geotextile is: a purely water-permeable geosynthetic material composed of textiles. A material that is used in soil, rock, earth, or other geotechnical engineering and serves a structural role as part of a human-made project.
PET filament fabric geotextile is directly made by polyester method through spinning and needle punching consolidation. The product specification is arbitrarily selected from 80-800gsm. PET filament fabric geotextile is a geosynthetic material used in geotechnical engineering and civil engineering. It is made by the method of polyester filament forming and consolidation, and its fibers are arranged into a three-dimensional structure. In addition to good mechanical properties, the PET filament fabric geotextile also has good vertical and horizontal drainage performance, good elongation performance, and high chemical stability such as biological resistance, acid and alkali resistance, and aging resistance. At the same time, it also has a wide pore size range, tortuous pore distribution, excellent permeability and filtration performance.
PET filament geotextile application
1.Reverse filtration of dams and slope protection in water conservancy projects, isolation and seepage prevention of channels;
2.Foundation isolation, anti-filtration, drainage, soil slope, retaining wall and pavement reinforcement and drainage of roads, railways, airport runways;
3.Soft foundation treatment of port engineering, reinforcement and drainage of beach embankments, harbour piers and breakwaters;
4.Polyester filament geotextiles have been widely used in the field of infrastructure construction, and are gradually being used in a wider range of fields.
Benefit
Application characteristics of PET filament geotextile
- Since the synthetic fibers currently used in the production of PET filament geotextiles are mainly polyester, they have strong anti-burial and corrosion resistance properties.
- The PET filament geotextile is a water-permeable material, so it has a good filter isolation function
- PET filament geotextile has good drainage performance due to its fluffy structure
- PET filament geotextile has good puncture resistance, so it has good protection performance
- PET filament geotextile has good friction coefficient and tensile strength, and has georeinforcement properties
Geomaterials In recent years, the extensive application and effectiveness of geosynthetics in rock engineering, especially in flood control and emergency rescue projects, have attracted great attention from engineers and technicians. For the application technology of geosynthetics, the state has put forward normative technical requirements in terms of anti-seepage, anti-filtration, drainage, reinforcement, protection, etc., which has greatly accelerated the promotion and application of new materials. The material has been widely used in canal anti-seepage engineering in irrigation areas.
Summary
PET filament geotextile function:
1.The good air permeability and water permeability of PET filament geotextile are used to allow water to pass through, thereby effectively intercepting sand loss.
2.PET filament geotextile has good water conductivity, it can form drainage channels inside the soil, and discharge excess liquid and gas in the soil structure.
3.The PET filament geotextile was used to enhance the tensile strength and anti-deformation ability of the soil, and to enhance the stability of the building structure, so as to improve the quality of the soil.
4.It effectively spreads, transmits or decomposes the concentrated stress to prevent the soil from being damaged by external force.
5.Prevent mixing between the upper and lower layers of sand, soil and concrete.
6.The mesh is not easy to block – the mesh structure formed by the amorphous fibrous tissue has strain and mobility.
7.High water permeability—under the pressure of soil and water, it can still maintain good water permeability
8.Corrosion resistance – using polypropylene or polyester and other chemical fibers as raw materials, acid and alkali resistance, non-corrosion, non-worm-eaten, anti-oxidation
9.Simple construction – light weight, easy to use, simple construction
PET filament geotextile has the following characteristics
Because PET filament geotextile has the above six functions, it can be widely used in railways, highways, sports venues, dams, hydraulic structures, tunnels, coastal roads, reclamation, environmental protection and other projects.
Application fields of PET filament geotextiles: water conservancy projects: seawall, river embankment, lake embankment compliance projects; reservoir reinforcement projects; reclamation projects; flood control and emergency rescue.
Highway and railway airport engineering: soft foundation reinforcement treatment; slope protection; pavement anti-reflection crack structure layer; drainage system; green isolation belt.
Electrical engineering: basic engineering of nuclear power plant; thermal power ash dam engineering; hydropower station engineering.
Port Channel Engineering: Port
