[Technical Information] What is Liquefiable Ground / What is Liquefaction Survey Method / Court Case Examples

[Technical Information] What is Liquefiable Ground / What is Liquefaction Survey Method / Court Case Examples

Why is liquefaction investigation necessary? We are publishing information about the risks of liquefaction and the investigation!

This document introduces ground that is prone to liquefaction, methods for liquefaction investigation, and case studies related to litigation. Since the Great East Japan Earthquake, liquefaction has become widely recognized in society. In the future, it may be judged as something that can be anticipated based on legal precedents. We have summarized why liquefaction investigation is necessary, the risks of liquefaction, and the investigation methods using photos and diagrams, so please take a moment to read it. [Contents] ■ Case studies of litigation due to liquefaction damage ■ What constitutes ground prone to liquefaction ■ Methods for liquefaction investigation ■ Methods for determining liquefaction *For more details, please refer to the PDF document or feel free to contact us.

Soil Contamination Survey "Green Test"

Soil Contamination Survey "Green Test"

We will diagnose the "land of concern" and give it a stamp of approval as "land that can be sold and lived on with peace of mind"!

At House Stage, we conduct a "Green Test" to diagnose land. We carry out three assessments: "Ground Investigation" to understand the hardness and softness of the ground and any obstacles in the deep layers, "Subsurface Exploration" to check for the presence of underground obstacles, and "Soil Diagnosis" to determine if there is any soil contamination. Selling land with issues such as underground installations, weak ground, or soil contamination can lead to significant problems with business partners later on. By conducting a ground diagnosis, the risks hidden in the land become clear. Would you like to add invisible value and provide land with greater peace of mind? 【Implementation Details】 ■ Ground Investigation ■ Subsurface Exploration ■ Soil Diagnosis *For more details, please refer to the PDF document or feel free to contact us.

Geophysical exploration technology service "Tunnel Shallow Reflection Method Exploration (SSRT)"

Geophysical exploration technology service "Tunnel Shallow Reflection Method Exploration (SSRT)"

It is a face-forward exploration technology using the VSP processing method.

The "Shallow Seismic Reflection Survey for Tunnel (SSRT)" is a technology that uses elastic waves to predict the geology ahead of a tunnel face. It was jointly developed with Fujita Corporation for the purpose of exploring the area in front of the tunnel. Since it is possible to select artificial seismic sources (hydraulic impactors, vibrators, blasting sources) according to the conditions of the tunnel site being excavated, there are no limitations on the applicable tunnels. For example, it can also be implemented in mechanically excavated tunnels that include Tunnel Boring Machines (TBM). 【Features】 - It can be conducted outside the tunnel construction site before excavation. - Exploration is possible in hard rock formations, soft ground, tunnel entrance areas, and low cover sections. - Since exploration behind the tunnel face is also possible, it allows for a more accurate evaluation of forward exploration by comparing it with excavation results. For more details, please contact us or download the catalog.

Technical Introduction: "Detection of Special Underground Shelters Using High-Frequency CSMT Exploration Method"

Technical Introduction: "Detection of Special Underground Shelters Using High-Frequency CSMT Exploration Method"

Confirmed high accuracy in practical experiments compared to other exploration methods!

At Geochronology Japan Co., Ltd., we can detect special underground cavities using the "High-Frequency CSMT Exploration Method" with cavity scanners. This exploration method allows us to determine the location of cavities without setting up a grid of measurement lines by utilizing the shadow effect. This technique has made it possible to detect high-resistivity materials, which were previously considered difficult to identify, thanks to the "Near-Field Amplifier Effect." 【Features】 ○ Grasp the approximate location of cavities across a wide investigation area ○ Determine the location of cavities with high resolution → The "Near-Field Amplifier Effect" reveals what was previously invisible with existing methods ○ Achieve a high soil cover ratio (depth to cavity / height of cavity: H/d ratio) ○ High versatility ○ Registered with NETIS, Patent No. 4229371 obtained For more details, please contact us or download the catalog.

Hot Spring Water Quality Source Investigation

Hot Spring Water Quality Source Investigation

Methods for water quality source investigation to minimize the economic risks of hot spring development projects.

In planning the development of hot springs, it is necessary to combine thoroughly considered survey methods based on the topographical and geological conditions of the target area. Our company conducts various methods, including "geochemical exploration," which involves the exploration of underground mercury gas, soil mercury, surface radioactivity, and underground carbon dioxide, as well as "CSA-MT method exploration," which advances considerations such as aquifer depth to serve as foundational data for determining drilling depth, to carry out the most suitable hot spring and water source surveys in the investigation area. 【Main Survey Methods】 ■ Aerial photo interpretation, topographical data analysis, Landsat data analysis ■ Surface geological surveys ■ Geochemical exploration ■ CSA-MT method exploration *For more details, please refer to the catalog or feel free to contact us.

3D radar road inspection and exploration service

3D radar road inspection and exploration service

You can take multiple cross-sections of vertical, horizontal, and plan views on-site!

Our company offers road inspection and exploration using 3D radar surveying. By measuring three cross-sections—longitudinal (in the direction of travel), transverse (across the road), and horizontal (depth)—quickly and with high precision, we can rapidly and accurately obtain more detailed data. Additionally, the data obtained through analysis can be reflected in plans and cross-sectional diagrams alongside geological data and topographical information. 【Benefits of 3D Radar Surveying】 ■ It is possible to obtain multiple cross-sections, including longitudinal, transverse, and plan views, on-site. ■ The time required for what used to involve multiple back-and-forth trips in conventional radar surveying can be significantly reduced. ■ Exploration can be conducted while driving on public roads without road restrictions (can accommodate speeds of 50-60 km/h). ■ By emitting multiple electromagnetic waves simultaneously, it is possible to explore through the gaps in rebar mesh (depending on the spacing of the mesh). *For more details, please download the PDF or contact us.
