Active in measures for steep slope collapse prevention, slope protection, reinforcement work, and seismic reinforcement work.

Here are examples of the introduction of "Grundomat" in water supply pipes, supply pipes, and anchors. In the case of bringing water pipes and gas pipes into homes, there are various structures such as walls, slope collapse protection stones (blocks), and stairs that can incur significant costs for restoration if damaged. "Grundomat" is effective in such situations. It can also be used for replacement work of aging pipes and lead pipes. 【Examples】 ■ Gas pipe installation work for "Kiyomizu Temple" in Kyoto ■ Disaster prevention work (measures against steep slope collapse, slope protection, reinforcement work) 　・ Measures against steep slope collapse 　・ Seismic reinforcement work *For more details, please refer to the PDF materials or feel free to contact us.

Introduction of water supply pipe road crossing work, water distribution works, and tie rod construction for railway foundations.

We would like to introduce a case where "Grundomat" was implemented in railway, road, and waterway crossing and tie rod construction. "Grundomat" is a self-propelled drilling machine that automatically penetrates the ground using a piston activated by compressed air. The piston inside the Grundomat strikes the head section with the power of compressed air, thereby compacting the soil and breaking up gravel while drilling. [Case Examples] - Road crossing construction for water supply pipes - Water distribution works - Tie rod construction for railway foundations *For more details, please refer to the PDF document or feel free to contact us.

It's like a mole moving through the ground with its own propulsion! The piston strikes the head section with the power of compressed air, compacting the soil and breaking up gravel while drilling!

This is a self-propelled drilling machine that operates using compressed air to automatically penetrate the ground. The piston, powered by compressed air, strikes the head section, performing drilling while compacting the soil and crushing gravel and other materials. Because the main body and the head section are separated, it has a strong crushing force and excellent directional stability, offering superior performance compared to conventional hammers. Its lightweight and compact design allows for quick piping installation even in places that were extremely difficult to work in before, such as over fences or behind stairs. 【Features】 ■ The compacting propulsion force of Grundmart is four times that of a simple air hammer. ■ Extremely high compacting propulsion and crushing force. ■ Excellent straightness. ■ Lightweight and compact. ■ Enables quick piping installation in areas that were previously very difficult to work in. ■ Excellent adaptability to soil types. *For more details, please request materials or view the PDF data from the download section.
