三和ボーリング List of Products and Services

We perform 450mm diameter drilling using a down-the-hole hammer with a spindle-type machine. We excel in construction on slopes where heavy machinery cannot be used by utilizing monorails or our own unique temporary structures. In pile work, we drive piles deep into stable ground below the sliding surface to resist the forces trying to cause sliding, and in fencing work, we construct rockfall protection fences, avalanche protection fences, and landslide protection fences composed of posts with high rigidity and excellent displacement performance, as well as energy-absorbing buffer fittings. 【Construction Examples】 ■ Landslide Countermeasure Work - Pile Work ■ Slope Protection Work - Fencing Work *For more details, please refer to the related links or feel free to contact us.

• Earthworks

Horizontal hole boring is a technique that utilizes a rotary percussion drill to excavate horizontally. The diameter ranges from 65mm to 216mm, and excavation is possible up to approximately 100 meters. It is used for construction to eliminate groundwater that causes landslides, for drilling holes to insert tendons for anchor work, and for pre-drilling for ground improvement. 【Examples of Construction (Partial)】 ■ Landslide Countermeasure Work - Water collection boring - Water collection well construction - Ground anchor construction *For more details, please refer to the related links or feel free to contact us.

When making an engineering judgment about the ground, it is extremely important to understand the physical properties, mechanical characteristics, and deformation characteristics of the ground. Soil samples collected through ground investigation can provide more accurate results by conducting soil tests on representative samples. Soil tests allow for a quantitative and scientific assessment of the soil. By utilizing values measured through standardized testing methods, it is possible to determine soft ground conditions, select ground investigation methods, and choose foundation construction methods, thereby finding safe and economical design and construction methods for projects. 【Features】 ■ Assessment of soil condition ■ Assessment as a material ■ Assessment of stability ■ Assessment of soil strength and deformation characteristics ■ Assessment of soil compressibility ■ Assessment of construction management conditions ■ Useful for understanding the state of the ground environment *For more details, please refer to the related links or feel free to contact us.

• Geological Survey

In conducting geological surveys, the first step is to organize existing geological materials and quickly gather the latest foundational data on survey sites based on related academic journals, conference papers, and specialized books. The basis of geological and soil investigations is to walk, observe, and use a hammer to understand the geology. Boring is a technique used to collect cores for direct observation of strata and rocks; these cores are also used as samples for testing. Additionally, the boreholes can be utilized for logging and permeability tests. Our company provides prompt on-site responses and accurate measurements and analyses. 【Flow of Investigation and Analysis】 ■ Literature and Material Research ■ Surface Survey ■ Mechanical Boring ■ Sampling ■ Sounding ■ Physical Logging ■ In-situ Testing *For more details, please refer to the related links or feel free to contact us.

• Geological Survey

The "RT Wangard Clear Method" possesses various concrete protection capabilities such as salt resistance, carbonation prevention, and crack-following properties, and it is a method that complies with the "push-out test." Compared to conventional continuous fiber sheet methods, it allows for a reduction in construction time. By simply applying it, both "concrete protection" and "spalling prevention" can be achieved, making it effective for complex shapes like I-beams. 【Features】 ■ Visualization of deterioration conditions ■ Significant reduction in construction time ■ Excellent performance in concrete protection *For more details, please download the PDF or feel free to contact us.

• Civil Engineering Method

The "Regitect RT Method" is a concrete flaking prevention technique that exhibits remarkable substrate followability through a rapid-curing urethane membrane coating. Being a spray application method, it easily adapts to complex substrate shapes like I-beams and significantly shortens the construction period compared to conventional methods. Additionally, the main material, CV spray, cures within seconds when sprayed using a dedicated pressure pump, allowing for minimal weather impact and enabling work in low temperatures. 【Features】 ■ Excellent workability ■ Solvent-free resin ■ Stable coating properties ■ Superior coating performance *For more details, please download the PDF or feel free to contact us.

• Renovation and repair methods

The "Snow Shed Waterproofing System" is a waterproofing system that utilizes the "CV Spray Method," which has ultra-durable waterproof performance. Since it is a spray application method, it easily adapts to complex substrate shapes and can significantly shorten the construction period compared to conventional methods. Additionally, the specialized system cures within a few seconds after spraying, making it less susceptible to weather influences and allowing for low-temperature work, while also forming a seamless and highly water-tight waterproof layer. 【Features】 ■ Expected to have over 30 years of weather resistance and durability ■ Excellent workability ■ Solvent-free resin ■ Stable coating properties *For more details, please download the PDF or feel free to contact us.
