Environmentally friendly large-diameter boring method effective for steel pipe pile construction and temporary work in narrow spaces.
The "Mast Drilling System" is a large-diameter boring method consisting of a rotary drilling machine (mast drilling machine) installed on an auxiliary mast and a crane (mast drilling crane) that suspends the drilling tools. By supporting the load of the crane with the auxiliary mast, the system reduces the crane's load, enabling either miniaturization of the crane or expansion of the working radius. A significant feature is the ability to freely attach and detach the crane and auxiliary mast. The construction method involves selecting the appropriate system from three drilling methods (air rotary method, down-the-hole hammer method, mud rotary method) based on site conditions. It addresses various challenges faced in conventional large-diameter boring projects, such as the desire to minimize the working space and reduce environmental impacts like noise, vibration, and dust. 【Features】 ■ The crane and auxiliary mast can be freely attached and detached ■ No noise or vibration is produced ■ No industrial waste is generated ■ Dust generation is minimized ■ The working space is small *For more details, please refer to the catalog or feel free to contact us.

Company information
TANIGAKI Construction Co., Ltd. was founded in September 1954 as "Tanigaki Construction" in Misato Town, Kishu District, Wakayama Prefecture (now: Kimino Town), and was incorporated as "Tanigaki Construction Industry Co., Ltd." in May 1973. In 1996, the company name was changed to the current name "TANIGAKI Construction Co., Ltd." In July 2014, the headquarters was relocated to Nagase, Kimino Town, Kishu District, following the completion of a new office building, and has remained there to this day. Since its establishment, the company has been involved in public works, focusing on disaster prevention projects, geological surveys, design, and construction. The know-how cultivated through various projects such as "surveying, measurement, and design work," "landslide countermeasures," "slope disaster prevention projects," and "underground resource development" has become a significant asset. Our motto is to tackle challenges with a "proactive spirit." In other words, our goal is to develop the know-how we have cultivated so far with new ideas to provide even better solutions. To achieve this, we have introduced cutting-edge technology as well as unique technologies developed entirely in-house. From survey design to construction techniques that can respond to those designs, we aim to create new technologies and new value through consistent services, striving to be a nature-friendly company. We will continue to contribute to the construction of a safe and secure society.
