Geotextile drainage fabric, as a new material, has been widely used in water conservancy project construction with its excellent performance and characteristics. It is mainly used to replace the traditional granule to build the filter layer and drainage water. Because of its soil retention, water permeability, blocking resistance, and high cost performance, it is widely used in water conservancy projects.
Case Study
- Location: Indonesia
- Product: Geotextile Drainage Fabric
- Application:Geotextiles Drainage Fabric for dam Project in Indonesia
The Java Island of Indonesia is frequently flooded. Although its area is not large, Java Island is the most important agricultural production area in Indonesia, which is suitable for the development of the agricultural type in this region. The favorable condition for the development of agricultural cultivation is rice cultivation, so irrigation, generating power and other comprehensive benefits of large reservoir DAMS to ensure that agricultural irrigation areas to obtain stable water sources.
Due to the influence of construction, economy and other conditions, the dam slope protection is not only short in length, but also simple in process, especially in the selection of anti filtration materials, are relatively backward. With the operation of the reservoir at full load, slope collapse occurs from time to time. So the government bid for a product that had a counter-filtration effect.
Solution
Geotextile drainage fabric is a kind of good filter material, which can not only retain soil but also drain water. Geotextile drainage fabricis laid in all parts of the dam that need to set filter layer to play the filter function
our clients contacted BPM Geosynthetics, and described in detail what happened with this project,we recommend geotextiles drainage fabric with filtration effect to customers according to the successful cases of domestic reservoirs before, and tell customers that similar projects using geotextiles drainage fabric as filtration material for slope protection projects will achieve obvious effects, creating favorable conditions for the reservoir to play a greater benefit and better promote the development of farm rice industry.
Geotextile drainage fabric has good mechanical function, good water permeability, corrosion resistance, anti-aging, isolation, filtration, drainage, protection, stability, reinforcement and other functions, can adapt to the uneven base, can resist the construction of external force creep smaller, long-term load can still maintain the original function
Geotextile drainage fabric can create drainage channels in the sand structure to drain the excess liquid and gas out of the sand structure.And the building materials with different physical effects (particle size, proportion, consistency and relative density, etc.) (such as sand and sand, sand and gravel, sand and concrete, etc.) to do a good job of protection.So that the two or a variety of materials do not reduce, do not doping, always maintain the integrated structure and function of the material, so that the building load bearing force is enhanced.
Basic requirements for Geotextiles Drainage Fabric laying.
- The joint must intersect with the slope line. Horizontal joints shall be more than 1.5m away from the toe of the slope where they are balanced or where stress may exist.
- On the slope, one end of the geotextile drainage fabric is anchored, and then the coiling material is lowered to ensure that the geotextiles fabricis kept in a tight state.
- All geotextile drainage fabricshall be held down with sand bags, which will be used during the laying period and retained to the material above the laying.
Technical requirements for geotextile drainage fabric layout.
1.Grass-roots inspection: check whether the grass-roots level, solid, if there is a foreign body, should be handled properly.
- trial shop: according to the site situation, determine the size of the geotextile drainage fabric, after cutting for trial shop, cutting size should be accurate.
- Check whether the width of Salah is appropriate, and the lap joint should be flat and moderately tight.
- Positioning: use a hot air gun to bond the lap parts of the two pieces of geotextile drainage fabric, and the spacing between the bonding points should be appropriate.
- When suturing the lap joint, the suture line should be straight and the stitching should be uniform.
- After stitching, check whether the geotextile drainage fabric is laid smoothly and whether there are defects.
- such as the existence of unqualified phenomenon, should be repaired in time.
Benefits
- High strength: the use of high strength industrial polypropylene, polyester, nylon and other synthetic fibers as raw materials, with a high original strength.
- After woven into a regular interwoven structure, the comprehensive bearing capacity is further improved.
- Durability: the characteristics of synthetic chemical fiber is not easy denaturation, decomposition, weathering.
- It can maintain its original characteristics for a long time.
- Corrosion resistance: synthetic chemical fiber generally has acid resistance, alkali resistance, moth resistance, mold resistance.
- Water permeability: Woven fabric can effectively control its structural pores to achieve a certain water permeability.
- Convenient storage and transportation: because of the light weight, can be packed according to certain requirements, so the transportation, storage, construction and so on are very convenient.
Summary
Geotextile Drainage Fabric have excellent filtration, drainage, isolation, reinforcement, protection, with light weight, high tensile strength, good permeability, high temperature resistance, freezing resistance, aging resistance, corrosion resistance.
