Trench

Ground. Ground warfare involves three types of combat units: infantry, armor, and artillery. Infantry in modern times would consist of mechanized infantry and airborne forces. Is trench warfare still used? Tanks and aircraft largely negated the defensive advantages offered by trenches, but, when those technologies are absent from a battlefield, trench warfare tends to reappear. […]

Tanks and aircraft largely negated the defensive advantages offered by trenches, but, when those technologies are absent from a battlefield, trench warfare tends to reappear. In the 21st century trench warfare was utilized in both the Syrian Civil War and the Russian-backed conflict in eastern Ukraine. Does trench warfare still work? In fact, trench warfare […]

Many died in combat, through accidents, or perished as prisoners of war. But the majority of loss of life can be attributed to famine and disease – horrific conditions meant fevers, parasites and infections were rife on the frontline and ripped through the troops in the trenches. What was the number one cause of death […]

The last combat veteran was Claude Choules, who served in the British Royal Navy (and later the Royal Australian Navy) and died 5 May 2011, aged 110. The last veteran who served in the trenches was Harry Patch (British Army), who died on 25 July 2009, aged 111. What were the odds of surviving ww1? […]

The mortality rate ranged between 6% and 30%, with the highest in the armies of Serbia, Montenegro and the Turkish Empire, mainly due to large epidemics of cholera, typhoid and smallpox, against which the armies of other countries vaccinated their troops. What was the life expectancy of a ww1 soldier? A soldier’s average life expectancy […]

In the early 19th century, almost 100 years before World War I, Charles Macintosh crafted coats from rubberised cotton for the British military. Named after their inventor, the trench coat used to be known as ‘macs’. The coats were revolutionary because they were waterproof. What were trench coats used for in ww1? The trench coat […]

Of the 60 million soldiers who fought in the First World War, over 9 million were killed — 14% of the combat troops or 6,000 dead soldiers per day. The armies of the Central Powers mobilised 25 million soldiers and 3.5 million of them died. What were the odds of dying in ww1? As stated, […]

Almost every day some enemy artillery shells would fall on the trenches. One study suggested that one-third of all casualties on the Western Front were killed or wounded while in the trenches. What percentage of soldiers died in the trenches? Yet, as noted, they only made up between 43 and 32 percent of the Army […]

Unlike a new iPhone, Apple Watch, or even the AirPods Pro, your MacBook is not water resistant. And it certainly isn’t waterproof. If you spilled water or liquid on your MacBook, follow these instructions as closely as possible to stand the best chance at avoiding liquid damage. Can a Mac survive water damage? Once MacBook […]

Here’s a classic belted coat: the belt comprises the same fabrication and color of the coat, and you simply tie it around your waist, with a slight tail hanging down at the center. If you’re feeling a little bit more off-beat, you can tie it with the tail at the back, or slightly off-center. How […]

Divide the sum of the depths by the number of items you measured. In the example, 35 divided by 5 equals an average depth of 7 inches. What is mean depth formula? Mean depth is calculated by assigning a depth value to each space according to how many spaces it is away from the original […]

Multiply for a 4 to 1 Slope Multiply the pond depth by 4 to find the total length the pond must extend to achieve a 4:1 slope. If the depth is only 1 foot, for example, the pond must extend 4 feet. A total length of 12 feet is needed if the pond is 3 […]

OSHA requires employers to provide ladders, steps, ramps, or other safe means of egress for workers working in trench excavations 4 feet (1.22 meters) or deeper. The means of egress must be located so as not to require workers to travel more than 25 feet (7.62 meters) laterally within the trench. What is a good […]

Sloping involves cutting back the trench wall at an angle inclined away from the excavation. Shoring requires installing aluminum hydraulic or other types of supports to prevent soil movement and cave-ins. Shielding protects workers by using trench boxes or other types of supports to prevent soil cave-ins. What is slope in excavation? Sloping means a […]

Procedure Discuss: Certified soil scientists usually use a Clinometer or Abney level to determine slope. Find a slope to measure. Mount the slope finder on the back of a board or clip board with the top line parallel with the sighting edge. Set a calibrated stake at both the top and bottom of the slope […]

All simple slope excavations 20 feet or less in depth shall have a maximum allowable slope of 1:1. TABLE B-1. MAXIMUM ALLOWABLE SLOPES. SOIL OR ROCK TYPE MAXIMUM ALLOWABLE SLOPES (H:V)(1) FOR EXCAVATIONS LESS THAN 20 FEET DEEP(3) STABLE ROCK TYPE A (2) TYPE B TYPE C VERTICAL (90º) 3/4:1 (53º) 1:1 (45º) 1 ½:1 […]

the thickness of the bedding is 100 mm (4 in). For pipe diameters larger than 1350 nun (54 in). the thickness of the bedding is 150 mm (6 in). What size is standard drainage pipe? When a number of houses are joined to the same drainage system, 160mm pipe is generally used for the pipe […]

The Proper Trench Excavation Nominal Pipe Size (inches) Trench Width (inches) 4 28 6 30 8 32 10 34 How wide does my trench need to be? Generally, pipe manufacturers require a trench to be at least twice as wide as the diameter of the pipe. This allows enough space to snake small-diameter pipe from […]

The private (supply) pipe is to be laid at a minimum depth of 750mm and up to a maximum depth of 1350mm below finished ground level (in accordance with Water Supply (Water Fittings) Regulations 1999 G7. 7). However, where the pipe crosses the property boundary and enters the premise, the depth should be 750mm. What […]

You must divide by 27 because 1 cubic yard equals 27 cubic feet. The answer is the total cubic yards of your area. Using the same example, divide 7,000 cubic feet by 27 to get 259.3 cubic yards. What do you divide by to get cubic yards? To calculate cubic yards we use the formula: […]
