Can we put 4 pipes into one bore? If yes is there minimum diameter given using for example 1 inch pipe?

2) No you cannot put 4 pipes into one vertical borehole. However, it is common to put 4 or even 6 pipes in to one horizontal trench but you must leave between 18" and 24" between each pipe. A backhoe generally charges anywhere from 500 - 800 Kc/Hour.

When they are using width of the hoe 0.7m. 100m long and 1.5m deep is estimated to take about 9 hours to do. From this you can see that this option is quite cheaper but less popular, efficient and messier to do.

If a horizontal trench is cheaper, why is it less popular. Also, can they not get a wider bucket and possible a stronger backhoe. Horizontal loops are the most popular type of loop in North America because it is much less costly.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
