Type

• Continuous system To establish a series of diaphragm walls by repeatedly constructing an element with a three-shaft auger
• Element system To establish diaphragm walls by repeatedly construct ing preceding and escorting in an interval of one hole creating an element using a three-shaft auger
• Preceding system To establish diaphragm walls by the same method as the element system after working with a preceding system with an interval of one hole using a single-shaft auger

Features

• Good for blocking water flow
• Shortened work period and lower costs
• Low noise and low vibration and little damage to surrounding areas
• Quality depends on construction technologies
• Strength depends on quality of earth and sand.
