Geological Disaster Prevention

We deal with solving any geologic or ground issues in the planning, layout and building roads, bridges, tunnels, rivers and erosion control installations. We can also carry out activities to help with O&M, survey and inspection of existing structures, ground and slope disaster prevention, and planning for disaster response.

Inspection and Surveying
We can respond to a wide variety of needs, including: geological surveying for roads, bridges, tunnels, rivers and erosion control; environmental conservation hydrologic studies; landslide and steep slope surveying/measurement; ground/slope disaster surveying; road emergency inspection and checking of historical buildings.

Geological Survey

Perform various investigations and analyzes for structural design, slope disaster prevention measures, etc., such as machine boring, in-situ test, indoor test, geophysical survey, surface geological survey, and geological integrated analysis.

geology_classification1_2

Hydrologic Survey

Various surveys and analyzes for environmental preservation, such as survey on actual water use, meteor observation, water level observation, water quality analysis, hydrological analysis, penetration flow analysis (two-dimensional, three-dimensional).

geology_classification1_3

Slope Disaster Survey

Perform various investigations and analyzes for emergency response, disasters such as heavy rain, earthquakes, monitoring, falling rock, rock collapse and landslide countermeasure.

geology_classification1_4

Emergency Road Inspection

Perform various inspections for road maintenance such as road disaster prevention inspection, various facility inspections, consideration of priority order of measures, construction of various inspection and viewing systems.

geology_classification1_5

Historical Building Inspection

Achievement: Survey, survey, analysis to protect cultural properties.

Engineering Planning
We deal with solving any geologic or ground issues in planning, layout and building of roads, bridges, tunnels, rivers and erosion control installations. We can also carry out activities to help with O&M, survey and inspection of existing structures, ground and slope disaster prevention, and planning for disaster response.

Freestanding Retaining Wall

In order to prevent sediment-related disasters in steep slopes collapse countermeasures projects, selection of position of retaining wallwork, comparison and detailed design are carried out.

geology_classification2_3

Reinforced-earth Retaining Wall

In order to prevent falling rock damage from the slope surface, we conducted a falling rock simulation etc. to compare falling stone countermeasure work considering the harmony with the surroundings and carry out detailed design.

geology_classification2_4

Crib Wall with Steel Reinforcement

To prevent slope failures due to natural disasters such as guerilla heavy rain, comparative examination of slope countermeasures and detailed design are carried out.

Landslide countermeasure work

In order to alter the landslide topography by the road plan, comparative examination of the landslide countermeasure (ground anchor work, collection well work etc), detailed design.

Measures against soft ground

In order to prevent road damage due to scale earthquake and ground deformation, comparative examination and detailed design of soft ground soil countermeasures based on numerical analysis and arterial observation are carried out.

Proximity impact study

Two-dimensional FEM analysis verifies the influence of the construction of a new structure approaching an important structure such as an existing steel tower or railroad.

Aerial Geophysical Surveying
Aerial electromagnetic survey methods allow 3 dimensional measurement and interpretation of underground geological features through subterranean resistivity and distribution. This makes them extremely useful for geologic, landslide and other planning in mountainous areas where wide access to the surface is otherwise too difficult.

geology_classification3_1

Aerial Geophysical Surveying: Measuring

By installing survey equipment on a helicopter and flying along the terrain, we got ground information about 150 m underground

geology_classification3_2

Aerial Geophysical Surveying: Location

Survey around the planned route in the aerial physics exploration, incorporate the ground information in the approximate construction fee, reduce the risk of construction costs due to ground problems after construction starts.

geology_classification3_3

Aerial physics survey tunnel

By visualizing the scale and state of landslide at the tunnel entrance, we clarify the zone of concern of the crushed zone and spring water, prevent accidents from flooding.

geology_classification3_4

Aerial Geophysical Surveying: Landslides

Three-dimensional grasp of the slip surface depth improves the accuracy of the landslide mechanism analysis and also reflects the efficient and effective groundwater removal plan.
