Cutting The Trenches

Categories: DRAINAGE

There are ditching-machines that do efficient

work. The best are costly. Most of the work on farms will continue to

be done with ditching-spades. The ground should be moved when wet, so

that labor can be saved.



A line should be used to secure a straight side to the trench. The

grade should be obtained by means of a system of strings. If two light

poles be pushed into the ground at each 100-feet station, o
e on either

side of the proposed trench, and a string be drawn across at a point

5-1/2 feet above the bottom of the proposed trench, these strings will

be in line on a grade 5-1/2 feet above the grade the drain will have.

As the cut at the station is known, the height of the string above the

top of the stake is easily determined. These strings will reveal any

inaccuracy in the survey. The workman can test every part of the bottom

of the trench by use of a rod 5-1/2 feet high, the top end being

exactly in line with the strings when the lower end is placed on the

correct grade of the trench. This device is better than running water

where grades are slight.



A drain scoop should be used in bottom of the trench to make a resting

place for the tile that will prevent any displacement by the soil when

the trench is filled.
