What were sandbags used for World War 1?

The military has used sand bags for many years to absorb shock and projectiles. Sand disipates energy so when a bullet hits it, the shock is spread out among all the grains and the bullet stops. Soldiers hide behind sandbags to protect themselves. Sandbags can also protect buildings from the shock wave of bombs.


The Various Uses of Sandbags?

Sandbags are very basic items. Most commonly, bags are constructed out of polypropylene (though burlap is also used) and then filled with sand or soil. Sandbags are used to construct barriers by different groups for a number of varying reasons. The two most common users of sandbags are the military and flood control personnel. Because it is so cheap to make sandbags and relatively easy to dispose of them, they are a prime choice for emergencies but not usually the only defense employed. To hold water back, most cities or towns use a series of levees, dikes, or dams. When these leak or are overflowed, sandbags are brought in and used to help contain the flooding. They can be used in non-emergency situations to create a base for a new levee or dam. Though sandbag walls can be quickly and cheaply erected, some people have concerns about using sandbags in very bad situations. They worry that although the sandbags do soak up water, if the water seeps through the bags it can push small amounts of finer materials through the seams as it goes. In addition to this, sandbags that have been used to soak up water contain the same materials the water did. If the water was contaminated by chemicals, the sandbags are unsafe. In many more cases, the offensive contaminant is feces. Used sandbags must be disposed of at a proper landfill for this reason. The military uses sandbags to fortify defenses instead of as water soakers. The cheapness of using sandbags to create fortifications around buildings is a major plus, and so many different methods have been put into place which use sandbags for fortification. One such method is to create bags in shapes that allow them to be interlocked like bricks so that a portable defense structure is quickly created. Military leaders have also taken special ingredients and used them to create longer-use sandbags due to the fact that plain burlap and soil sandbags can fall apart and rot very quickly. Sandbags have even been used to create temporary housing for holding prisoners of war. Less pressing uses of sandbags include disposable weights for theater sets and gas air balloons. These simple little creations have been used for hundreds of years and are still used today for a variety of tasks.

How to Use Sandbags to Prevent Flooding?

Each year many towns and cities are devastated by the flooding of bays, lakes, oceans, and rivers.%C2%A0 While flooding can occur without notice, the damaging effects of floods can often be reduced or eliminated with the use of sandbags.%C2%A0 While sandbags are a simple solution, knowing how to properly fill and use sandbags to prevent flood damage can be confusing. %C2%A0 The first step in how to use sandbags to prevent flooding is to create sandbags.%C2%A0 Sandbags can be created with sand found and home improvement stores, beaches, or even a local playground.%C2%A0 Beyond the sand, you will need plastic or cloth sandbags, a wheel barrow, and a shovel.%C2%A0 When filling the sandbags, be sure to fill them until they are about a third of the way full.%C2%A0 When this full, the typical dry sandbag will weigh about 40 pounds.%C2%A0 Then take the leftover slack of the bag to fold over. %C2%A0 The next step in using sandbags to prevent flooding is to build your sandbag wall.%C2%A0 To build this wall, you will first need to dig a trench that is about 6 inches deep and 18 inches wide.%C2%A0 The dimensions may vary if you have larger or smaller bags.%C2%A0 After digging the trench, you will need to place a polyethylene sheet into the trench.%C2%A0 Once the sheet is placed, you will place the first row of sandbags into the trench.%C2%A0 The bags should be laid down so the left over slack from the bag will lie beneath the weight of the bag. %C2%A0 After building your first row of sandbags, the next step in building a sand bag wall is to build the next few rows.%C2%A0 The next row should be placed directly on top of the first row, although the sand bags should be placed in a staggered pattern.%C2%A0 Continue to build up the sand bag wall until the wall is about 4 rows high.%C2%A0 Beyond this point, the bags will begin to lose their sturdiness.%C2%A0 If you need to build your sandbag wall higher than 4 rows, you will need to build a wider trench and create a sandbag base of at least two rows wide.%C2%A0
