What is Sand Filled Mattress System?
PIONEERTEX Sand Filled Mattress (SFM) is the ideal choice when riverbanks,waterway sections and impoundment slopes require erosion control with a long-term vegetation cover in place. It's economical,easy to install and use simple equipment without the requirements for skilled labor.
SFM is manufactured with a special subtrate integrated to the upper surface for instant green effect, providing a texture surface that enhances the rapid establishment of vegetation and shielding UV attack.
SFM is deliveryed in rolls, which can be easily transported to job site. Laid with parallel tubular sections running down the slope each are hydraulically filled with sand through the top openings.The sand is introduced through a small hopper, and washed down with water pumped from the waterway or impoundment. Adjascent rolls of SFM are joined by seaming on site. Finally, the SFM was anchored in a trench at the top of slope.
Composite and properties
By its compostion, the system becomes a flexible and current resistant mat with excellent filter properties. Both filter cloth are soil tight and the upper cloth is extra stabilized against UV radiation. However, the cloth allow plants roots to penetrate thus providing extra protection to the construction.
Sand or gravel are the most suitable for fill material. Mixing seeds can be promoted vegetation. Protection will become part of the landscape and ecological system where it is safe and friendly system that allows opportunities for recreation activities.
Flood mitigation channels and protection works
Protection of the sea-bed around jetties
Navigational canals and waterways
Stability and Flexibility
SFM provides a stable mat which is able to withstand high currents and limited wave action. Irregularties on banks and beds are easily overcome. Flexibility mat will fall into the scouring and form a new line of protection neutralized the risk of soil erosion under mattress edges.
There are a few methods available:
Suitable for large areas of SFM have to be installed. Sand is blown through a flexible hoe into the SFM tubes using compressor and sand hopper with feeder.
Suitable for large areas where can be filled in a dry conditions. PVC pipe is inserted into the SFM tubes, sand is dropped though the fill-opning in the pipe and subsequently ramme down with a concrete rammer. Compacted sand ballast inside SFM is the advantage of this method.
The wet filling system is similar to the dry filling method using rammer. The sand is being washed down by a water jet. This will provides a more continous process with well compacted sand ballast in the SFM.
It is advised to anchor he mats on top of the slopes in a trench when SFM is being used on steep slopes or in the areas with strong currents or fluctuating water level.
What's the advantage of SFM system compared with other Erosion Control Blanket?
1. Make full use of the sand or sludge in the river for filling;
2. Vetegation establishment, and environment friendly;
3. No need labor for filling.
4. Fast filling, and finish the project in the short term.
5. Long Shelf life.
