Site investigation "Boring and Standard Penetration Test"

Site investigation "Boring and Standard Penetration Test"

The most effective survey method when planning civil engineering and construction projects.

The "Boring Standard Penetration Test" involves drilling into the ground to investigate the properties of soil. It uses the hole to examine the soil's hardness, compaction, soil type, and stratification. Since soil samples can be collected, it allows for direct visual confirmation of the soil's condition. In recent years, liquefaction has been a concern; however, this test can be used to measure water content, enabling the assessment of whether liquefaction will occur when combined with soil quality tests. **Features** - Liquefaction assessment is possible - Soil condition can be confirmed in the vertical direction (columnar diagram) - Soil properties can be understood through physical and mechanical tests **For more details, please download the catalog or feel free to contact us.**

Soil washing device "Instant Mixer DEM / Utilization System"

Soil washing device "Instant Mixer DEM / Utilization System"

We are challenging ourselves with technology utilizing the developed instant mixer "DEM."

The Soil Environment Process Research Institute, Inc. (abbreviated as DPK) conducts research on soil washing technology. The core technology of soil washing is a method that utilizes high-speed jet fluids to continuously disperse soil in water. It can disperse soil particles in water just like washing rice. This dispersion device (trademarked as DEM) is a product developed by DPK. In the soil washing process incorporating DEM, oil and fine sand from oil-contaminated soil and field sand are removed. The products of the Soil Environment Process Research Institute include the rental of DEM and contract research for the washing process. [About Soil Washing Technology] - DEM is a technology that utilizes high-speed jet fluids to continuously disperse soil in water. - Soil treatment capacity record: 0.1 to 15 tons/hour. - Patent No. 4990326: Device for producing a mixture of soil and water using high-pressure water. For more details, please contact us or download the catalog.

Geological age dating "TL dating"

Geological age dating "TL dating"

Utilized for dating geological eras! An explanation of "TL dating."

The age value of minerals is related not only to the time since the mineral was formed (the time since the mineral cooled to several tens of degrees Celsius), but also to the intensity of radiation exposure per unit time and the specific properties of that mineral. The 'TL age' value is given as the ratio of the fossil dose (PD) or equivalent dose (ED) received by the target mineral since its formation to the annual dose (AD) that the sample receives per year. In dating fault clay and metamorphic rocks, the TL signal that has accumulated since the formation of the rock is lost (annealed or reset) due to frictional heat from fault movement or the heat from hot spring water, and by measuring the signal that has accumulated again afterward, the age of fault movement or metamorphism can be estimated. *For more details, please refer to the catalog or feel free to contact us.

Hollow scanner

Hollow scanner

Detection of high resistivity materials using high-frequency CSMT exploration method.

The "Cavity Scanner" can grasp the approximate location of cavities within a wide range of survey areas. By utilizing the shadow effect, it is possible to determine the position of cavities with high resolution without setting up grid-like measurement lines. Thanks to the near-field amplification effect (undergoing posting), the MT parameters are amplified while retaining the shape corresponding to the cavity. With the "near-field amplification effect," things that were not visible with existing methods can now be seen. 【Features】 ■ Near-field amplification effect ■ High-resolution determination of cavity positions ■ Achieves a high overburden ratio ■ High versatility *For more details, please refer to the catalog or feel free to contact us.

Improved elastic wave exploration service

Improved elastic wave exploration service

NETIS, registered as a patent! This method allows for the overall evaluation of the embankment in a planar manner.

Our company has developed an "Improved Elastic Wave Exploration" method to quantitatively and spatially evaluate the integrity (deformation level) of mass concrete in dams, which is being utilized in sand control dams nationwide. By setting up vibration points around the dam, we analyze the elastic waves that pass through the concrete in both vertical and horizontal directions, visualizing the elastic wave velocity distribution spatially and evaluating it quantitatively. The on-site work takes about 1 to 2 days, and the analysis results are organized visually in an easily understandable manner using contours and meshes. 【Awards and Achievements】 ■ Infrastructure Maintenance Award: Excellence Award (Received in 2021) ■ NETIS Registration Number: KT-190137-A (Registered in 2019) ■ Patent Registration Number: No. 6396074 (Registered in 2018) *For more details, please refer to the PDF materials or feel free to contact us.

Soil contamination survey (voluntary survey and legal/regulatory survey)

Soil contamination survey (voluntary survey and legal/regulatory survey)

Soil contamination is an invisible asset retirement obligation. We propose investigations that take into account measures for soil contamination.

Our company is a "designated investigation agency based on the Soil Contamination Countermeasures Act of the Ministry of the Environment." Currently, there are about 698 designated investigation agencies nationwide, but we are one of the few companies that consistently handle everything from soil contamination surveys to soil contamination countermeasure construction. The cost of countermeasure construction is said to be between ¥50,000 and ¥100,000 per cubic meter of contaminated soil, and to further reduce these costs, we propose "forward-looking investigations" that leverage our strength in conducting countermeasures! You can entrust us with everything from voluntary investigations for land transactions to investigations in accordance with various regulations and legal investigations. ■ We own our own drilling machines for contamination surveys (a total of 13), ranking among the top in the industry! ■ From consulting to on-site surveys to countermeasure construction, we provide a one-stop service with our own staff! ■ Of course, we serve all of Japan! *For more details, please refer to the PDF materials or feel free to contact us.
