Tunnels and underground excavations,horizontal underground passageway produced by excavation or occasionally by natures action in dissolving a soluble rock,such as limestone.A vertical opening is usually called a shaft.Tunnels have many uses for mining ores,for transportationincluding road vehicles,trains,subways,and canalsand for conducting water and sewage.tunnels and underground excavations History,Methods Tunnels and underground excavations,horizontal underground passageway produced by excavation or occasionally by natures action in dissolving a soluble rock,such as limestone.A vertical opening is usually called a shaft.Tunnels have many uses for mining ores,for transportationincluding road vehicles,trains,subways,and canalsand for conducting water and sewage.What Type of PVC Pipe Should I Use Underground? HunkerUse different types of PVC pipe for underground installation than you would for above-ground,in-house installation.Wall Thicknesses PVC pipe comes in different schedules (meaning wall thicknesses),the most common being Schedule 40,80 and 120.Schedule 40,used for general household above-ground sewer and vent lines,has thinner walls,while
