Exhibition of Promoting the Elimination of Utility Poles / We will be exhibiting at Maintenance and Resilience TOKYO 2019!

A catalog with construction examples is presented! It excels in narrow spaces and on slopes where transporting heavy objects is difficult! There is no generation of excavated soil!

Grundmart is a "no-dig, easy-push penetration machine" that can perform replacement work on aging pipes for water, gas, electricity, and communication without the need for large scaffolding or temporary structures. This method is accessible to anyone and can be utilized in microtunneling for water, gas, electricity, and communication construction, among others. Since it does not require large temporary structures like scaffolding, it is also effective for preventing landslides on slopes and for anchor, tie rod, and rock bolt construction. <Features of Grundmart> ■ Enables piping construction in locations that were extremely difficult to work in previously, in a short time ■ High precision and durability ■ Two impact systems ■ High reliability ■ The compact thrust power is four times that of a simple air hammer *For more details, please refer to the PDF materials or feel free to contact us.

With the evolved Grundmart N type, towards innovative technology and high efficiency.

This catalog introduces the evolved Grundomat N type (air-operated underground drilling machine) for more reliable construction. The new Grundomat N type has been developed to accommodate various soil conditions, including hard soil and gravel mixed soil, which were previously challenging. A crown head with high crushing efficiency for gravel and similar materials has been installed. [Contents (excerpt)] - Innovative technology for high efficiency - Selectable head types: Crown or Step - two options - Selection between crown head and step head - Operating principle of the step head - Applications, etc. *For more details, please refer to the PDF document or feel free to contact us.

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.

The area surrounding the ground mart is compacted more than the natural ground.

We would like to introduce a case where "Grundmart" was implemented in ground reinforcement and support piles. This involves the construction of driving piles down to the supporting layer during building. It is used as an easy method for ground reinforcement during new construction and for support piles in earthquake recovery work. Additionally, it is also possible to insert commercially available single pipes into the holes created by Grundmart. 【Case Studies】 ■ Ground Reinforcement Work ■ Support Pile Work *For more details, please refer to the PDF materials or feel free to contact us.

Introducing the main equipment and optional items of Grundmart!

The "Grundomat" is a self-propelled drilling machine that automatically penetrates the ground using a piston activated by compressed air. This product comes with a variety of "main equipment and optional items." When simultaneously pulling in the Grundomat along with installation pipes or protective pipes, various types of pipes can be accommodated by converting the rear of the Grundomat. *For more details, please refer to the PDF materials or feel free to contact us.

Pursuing further efficiency in development! Significant improvements in propulsion power and speed!

The "Grundmart P Type" has been developed to pursue even higher efficiency than conventional models. The significant feature of this product's enhanced efficiency lies in its improved unique head system. By adopting a structure that impacts the casing, both the propulsion power and speed have been greatly improved, and the switching between forward and reverse has been simplified to just the rotation operation of the air hose. Additionally, a short version called "PK Type" is also available. 【Features】 ■ Improved unique head system ■ Significant increase in propulsion power and speed ■ Simplified switching between forward and reverse *For more details, please refer to the PDF document or feel free to contact us.

Select the appropriate advancement speed according to the soil conditions! Capable of handling various soil conditions!

The "Grundmart N Type" has been developed to accommodate various soil conditions, including hard soils and gravel-mixed soils, which have traditionally been difficult to work with. A major feature of this product is the "Crown Head," which is highly efficient in crushing gravel and similar materials. Additionally, it has been designed with a two-stage variable speed forward system that allows for the selection of an appropriate thrust speed (number of impacts) based on the soil conditions. 【Features】 ■ Highly efficient "Crown Head" for crushing gravel and similar materials ■ The Crown Head section can also accommodate the conventional multi-cutter cone type ■ Compatible with various soil conditions ■ Adopts a two-stage variable speed forward system *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.
