most combatants at that time NEVER built straight trench's.
1. If a shell struck in to the trench, the shrapnel would go flying everywhere in the trench if it was in a straight line, the "curve" in the trench would deflect the shrapnel.
2. if part of the trench was overrun, resistance could still continue with a zigzag trench.
If it was in a straight line, enemy soldiers could just fire there guns in a straight line and kill everyone easily.
At the front there was the front line, then there was the support trench and at the back was a reserve trench.
Front-line trenches were not dug in straight lines. Otherwise, if the enemy had a successive offensive, and got into your trenches, they could shoot straight along the line. The French tended to build zig-zag trenches. However, the British Army preferred a system where each trench was dug with alternate fire-bays and traverses. Whereas fire-bays were straight sections of trenches, traverses were built at angles. This limited the effect of enfilade fire or shell-burst

the reserve trench were the lin eof trenchs that are behind the front lin trench. if or when the front line trench is captured, the solidiers can use the reserve trench line and the substitute front line
As a defensive measure, in case the front trench was overrun.

The front wall is a parapet the back is a parados.
To install a trench drain in front of a garage, you will need to dig a trench, place the drain in the trench, connect it to the existing drainage system, and then fill the trench with gravel or concrete. Make sure the drain slopes away from the garage to ensure proper drainage.
Frontline trenches were usually about seven feet deep and six feet wide. The front of the trench was known as the parapet. The top two or three feet of the parapet and the parados (the rear side of the trench) would consist of a thick line of sandbags to absorb any bullets or shell fragments. In a trench of this depth it was impossible to see over the top, so a two or three-foot ledge known as a fire-step, was added. Trenches were not dug in straight lines. Otherwise, if the enemy had a successive offensive, and got into your trenches, they could shoot straight along the line. Each trench was dug with alternate fire-bays and traverses. Duck-boards were also placed at the bottom of the trenches to protect soldiers from problems such as trench foot. Soldiers also made dugouts and funk holes in the side of the trenches to give them some protection from the weather and enemy fire. The front-line trenches were also protected by barbed-wire entanglements and machine-gun posts. Short trenches called saps were dug from the front-trench into No-Man's Land. The sap-head, usually about 30 yards forward of the front-line, were then used as listening posts. Behind the front-line trenches were support and reserve trenches. The three rows of trenches covered between 200 and 500 yards of ground. Communication trenches, were dug at an angle to the frontline trench and was used to transport men, equipment and food supplies.
