Japan with a lot of steap mountains is under geographical environment that is apt to cause sediment-related disasters such as landslide and debris flow induced by earthquake, typhoon or heavy rain. There are 520 thousand hazardous palces of sediment-related disaster all over the country and about 1000 sediment-related disasters occur every year throughout the country.
The investigation at the place occurring landslide is carried out by drilling survey and drilling technology is also applied as the countermeasure of Landslide Prevention Work. We can provide the equipment securing the safety and improving operating efficiency for Landslide Prevention Work, meeting the requirement from our customers.

Control Work

In order to drain the groundwater inducing landslide, horizontal drilling method by drilling horizontally from ground surface to drain the groundwater, or water collecting method by drilling horizontally from large diameter (3.5 m) water well is applied.

Large size drill（TOP）　Horizontal drilling

TOP-LS21, TOP-MM and TOP-SS drills are specially designed for horizontal drilling and enable horizontal drilling in fractured formation. The function of drill has dual tube system to rotate outer casing and inner rod simultaneously. Drilling proceeds as inner bit drills inside outer casing and outer bit drills around outer casing by protecting inner rod from the jamming or formation collapse for smooth penetration of inner rod. Model is selectable depend on rotation torque, feed force and balance force meeting the requirement of drilling depth.

These drills are utilized not only for retaining work for landslide prevention, but also for pilot dewatering hole drilling which was applied for "Jouetsu Super Express Railway" and "Seikan Tunnel" projects, Scientific Investigation, horizontal grout hole drilling for ground improvement and the installation work of various size of pipes for water supply and sewage.

We can offer the equipment with "Only One" features upon customer's request.
