The "Spider Drilling Method" uses extremely small and lightweight drilling machines, allowing for the construction of rebar insertion work while reducing temporary construction. Since a crane type does not require temporary scaffolding, it can be removed immediately after rebar insertion. It is effective when multiple types of work overlap, such as reverse construction. Additionally, it demonstrates its strength when there are restrictions on traffic regulation or usage time at the base of slopes. It shortens the lead time between different types of work, significantly reducing construction costs and days. 【Features】 - No temporary scaffolding required. Minimal temporary construction is acceptable. - Effective when multiple construction works are congested. - Suitable for slope work and measures against landslides on steep slopes. *For more details, please refer to the materials. Feel free to contact us with any inquiries.

This document presents a case study of the "Mast Drilling System" by Tanigaki Construction Co., Ltd., which is engaged in consulting services, landslide countermeasures, and slope disaster prevention projects. The construction ordered for a large-diameter boring machine was carried out using the air rotary method. As a result, we were able to reduce scaffolding work by 680 cubic meters and shorten the construction period by 51 days. By not using muddy water, we completed the project without generating industrial waste. After completion, the main contractor received additional points for their construction performance due to the active use of the new method developed in the prefecture. Due to the positive feedback, we were selected for continued work in the following year. 【Overview】 ■ Project Name: Heisei 24 Fiscal Year Wide Area No. 1-22 Nishi-Hata Road Construction in the Left Bank Area of the Kinokawa River ■ Client: Wakayama Prefecture Ito Promotion Bureau Construction Department ■ Construction Location: Nishi-Hata, Hashimoto City, Wakayama Prefecture ■ Construction Period: August 13, 2013 – February 14, 2014 ■ Construction Details: Steel pipe piles φ508.0mm Excavation length 18.5m – 22.0m, 24 pieces *For more details, please refer to the catalog or feel free to contact us.

The "Remicon Blow System" is a compact and high-performance mortar spraying system that is effective for small-scale applications in narrow or emergency situations. Instead of mixing mortar on-site, it is produced at a ready-mixed concrete plant and delivered using mixer trucks. This allows for a reduction in the space required for material placement while increasing the flexibility of placement, and it enables easy and reliable quality control of mortar production. 【Features】 ■ Factory-produced sprayed mortar ■ Stable quality of mortar ■ Suppression of noise, dust, and wastewater generation ■ Minimal equipment usage, reducing occupied area ■ Ability to use high-strength mortar *For more details, please refer to the catalog or feel free to contact us.

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.

The "Spider Drilling Method - No Scaffolding Type" is a recommended method for performing rebar insertion work under special conditions where market unit prices cannot be applied. It is particularly effective for long slopes where temporary scaffolding would become large, and for work at extremely high altitudes. It is ideal for sites where temporary scaffolding cannot be installed due to obstacles at the bottom of the slope, such as slope protection on steep terrain. Additionally, it can reduce construction costs and construction days with minimal temporary work. 【Features】 ■ Optimal for long slopes and high-altitude work ■ Ideal when scaffolding cannot be installed due to obstacles at the bottom of the slope ■ Reduces the required construction space ■ Minimizes construction costs and days with minimal temporary work *For more details, please refer to the catalog or feel free to contact us.

The "Spider Drilling Method" is recommended for carrying out rebar insertion work under special conditions where market prices cannot be applied. Considering the site conditions, the optimal work type is selected from three options: "scaffold type," "no scaffold type," and "crane type." Additionally, depending on the conditions of the ground being worked on, either "single pipe drilling" or "double pipe drilling" methods can be chosen, allowing for adaptation to unstable ground conditions. 【Features】 ■ Choose from scaffold type, no scaffold type, and crane type ■ Optimal for special conditions ■ Can reduce construction space ■ Reduces construction costs and duration with minimal temporary works ■ Shortens the construction period and costs for rebar insertion work *For more details, please refer to the catalog or feel free to contact us.

The "Safety Climber Method" is a construction technique that uses a drilling machine called "Kenfighter" to excavate and shape high places and steep slopes. The machine maintains balance by suspending wires and is operated remotely via wireless control, ensuring the safety of the workers during operation. Using a remote-controlled unmanned drilling machine, the operator can safely control it from a distance. Additionally, since it is suspended by wires, there is no risk of falling hazards even if the ground beneath it collapses. 【Features】 ■ Safe remote operation from a distance ■ Safe and speedy demolition of sprayed mortar ■ No need for access roads or heavy machinery scaffolding ■ Unique wire installation method allows for free movement up, down, left, and right ■ Safe even if the ground beneath it collapses due to being suspended by wires *For more details, please refer to the catalog or feel free to contact us.

Until now, rock bolts required a 10 cm anchorage length above the ground surface, and this part was covered with a protective cap, causing a significant protrusion above the ground. However, the new rock bolts will eliminate this protrusion by flattening the head anchorage material. Additionally, the protective caps that have been used until now were filled with anti-corrosion oil, posing a risk of oil leakage. The flat cap does not use anti-corrosion oil, making it safe to use even near rivers and dams. 【Advantages (Features)】 ■ The landscape of the reinforced slope looks neat ■ It does not break even when hit by falling rocks ■ It does not obstruct the passage of pedestrians or vehicles ■ There is no concern about oil leakage ■ Cost-effective *For more details, please download the catalog below.

We would like to introduce examples of the environmentally friendly large-diameter drilling method, the "Mast Drilling System." The "Mast Drilling System" features characteristics such as "no industrial waste generation," "no noise or vibration," and "no dust generation." The "Mast Drilling System" was registered in 2008 in Wakayama Prefecture as "Kensanpin." 【Case Examples】 ○ Construction Location: Kishu Town, Wakayama Prefecture → There are challenges such as the inability to use mud water for drilling within the river. ○ Construction Location: Nogami Town, Wakayama Prefecture → There are challenges such as the need to reduce the impact of noise and vibration due to proximity to residential areas.
