MLT Method (No-Dump Hole Wall Method)

Achieve cost reduction and shorten construction periods! A new method for hard ground containing stones and other materials!

The "MLT Method (No-Debris Hole Wall Method)" is a hard ground excavation method that compresses excavated soil against the hole wall using a special screw consisting of a compression wing and a mixing wing, without generating industrial waste. The special screw with a compression wing pushes the excavated soil into the hole wall, reducing the void volume ratio and allowing the hole wall to stand independently. Therefore, it is possible to reduce the amount of excavated residual soil. As the hole wall is compressed, the friction on the screw decreases, allowing most of the force to be applied to the tip bit, which efficiently cuts through bedrock and hard boulders. Additionally, the self-supporting hole wall reduces the rotational reaction force on the screw, making the base machine only 40% of that of conventional machines, which makes it suitable for narrow spaces. 【Features】 ■ Achieves cost reduction and shorter construction periods compared to conventional methods ■ Demonstrates power in drilling cobbles and boulders ■ Reduces excavated residual soil ■ Increases construction speed ■ Efficiently cuts through bedrock and hard boulders ■ Suitable for narrow spaces *For more details, please refer to the PDF document or feel free to contact us.
