Moling
From Wikipedia, the free encyclopedia
Moling is the common term used for laying pipes without digging trenches. Typically the same type of towable air compressor as is commonly used for road repairing pneumatic drills is employed. The compressed air is used to drive the mole forward through earth. Moling is frequently used to lay water pipes, but is also used for the heating coils of heat pump systems.
The standard approach is to dig a hole about 1m square and 2m deep. Such a hole is small enough that, in inaccessible locations, it can be dug by hand instead of by machine. The mole is then entered into the earth on the horizontal face at the bottom of this hole. A destination hole of similar proportions is also dug, and this is where the mole emerges. The mole itself is a steel cylinder about 60cm long and 6cm in diameter. It works as a piston with pulsed compressed air causing the head of the mole to repeatedly hammer against the earth in front of the mole. Once the mole has passed through the earth the water pipe can be pulled through the long horizontal hole.
To lay a water pipe of some 100m in length can cost £1500 including equipment rental, labour and materials. The water pipe pulled through the hole may be blue PVC 4cm in diameter.
The Molings are a family which contains two fantastically sexy half asian children. Be warned ladies; the one known as "Ryan" is incredibly bodacious. This child (a male) ought not to be fed any dairy products, but the other, "Jenny," loves cheeses.
