Description:
A sandbag is a bag or sack made of polypropylene or other sturdy materials that is filled with sand or soil and used for such purposes as flood control, military fortification in trenches and bunkers, shielding glass windows in war zones, ballast, counterweight, and in other applications requiring mobile fortification, such as adding improvised additional protection to armoured vehicles or tanks.
The advantages are that the bags and sand are inexpensive. When empty, the bags are compact and lightweight for easy storage and transportation. They can be brought to a site empty and filled with local sand or soil. Disadvantages are that filling bags is labor-intensive. Without proper training, sandbag walls can be constructed improperly causing them to fail at a lower height than expected, when used in flood-control purposes. They can degrade prematurely in the sun and elements once deployed. They can also become contaminated by sewage in flood waters making them difficult to deal with after flood waters recede. In a military context, improvised up-armouring of tanks or armoured personnel carriers with sandbags is not effective against cannons (though it may offer protection against some small arms).
Application:
1.Flood control
Sandbags can be used to build levees, barricades, dikes and berms to limit erosion from flooding. Sandbags can also be used to fortify existing flood control structures and limit the effects of sand boils. Sandbag structures do not prevent water seepage and therefore should be built with the central purpose of diverting flood water around or away from buildings.
2.Frotification
The military uses sandbags for field fortifications and as a temporary measure to protect civilian structures.
Sandbags have traditionally been filled manually using shovels
3.Bulk bags
Bulk bags, also known as big bags, are much larger than traditional sandbags. Moving a bag of this size typically requires a forklift truck. Bulk bags are usually made of woven or non-woven geotextiles.
Characteristics:
1.The material is environmentally friendly.
2.Customized printing.
3. PP woven bag is strong, puncture-resistant and tear-resistant, which is better than paper bag. 4. Widely used in agriculture, chemical products, building materials, industry, food and other fields.
