Geological survey

Geological survey

Rapid on-site response and accurate measurement and analysis! Introducing our geological survey services.

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: "Laboratory Soil Tests and Rock Tests"

We also accommodate special tests outside of JIS and JGS standards! We provide the data that our customers need.

At Kyoa Development, we conduct "Indoor Soil Testing and Rock Testing," where we perform laboratory tests on soil and rock samples collected on-site to evaluate the physical, chemical, strength, and deformation characteristics of the ground. The "Indoor Soil Testing" is carried out using sampling materials (undisturbed samples and disturbed samples) to understand the physical and mechanical properties of the ground. Additionally, we accommodate special tests that are not covered by JIS or JGS standards, providing the data that our clients require. Our testing centers are located in two places: Kanto (Chiba City, Chiba Prefecture) and Kansai (Sakai City, Osaka Prefecture), and we also welcome clients to attend the tests. 【Features】 ■ Indoor testing ■ Support for special tests beyond JIS and JGS standards ■ Provision of data required by clients ■ Attendance at tests is also supported *For more details, please refer to the PDF materials or feel free to contact us.

Construction consultant services - geological survey

Construction consultant services - geological survey

Geological survey related to construction work.

In construction work, the ground plays various roles as a material for structures, as a support foundation for structures, and in terms of stability, the influence of groundwater, and the impact on the ground environment. Since the survey results are used as reference materials for planning, design, and construction at various stages of construction work, geological surveys need to be conducted using methods selected according to the situation and purpose at each site.

Geological Survey "Exploration Boring"

Geological Survey "Exploration Boring"

Geological survey capable of understanding ground information according to the purpose of the investigation.

Our company offers "investigation drilling," which is diversified at each stage from preliminary surveys to main surveys, as one of the important methods for geological surveys. Primarily, rotary drilling is used, where the drilling rod or core barrel driven by the drilling machine is equipped with a bit that rotates and is subjected to bit load provided by the machine's feed force, allowing it to cut through the ground while advancing the hole. 【Features】 - Not only excavating the actual ground but also conducting various sampling and in-situ tests in conjunction with it. - Enables understanding of ground information according to the survey purpose. - Allows for drilling from soil to bedrock by selecting bits suitable for the ground. *For more details, please download the PDF or feel free to contact us.

Geological survey of small cross-section tunnels

Geological survey of small cross-section tunnels

Quantitative surveys of ground loosening and cavities around small cross-section tunnels have become possible.

**Necessity and Background** - In waterway tunnels that have been constructed for some time, cavities may form behind the lining due to water leakage. These cavities can cause loosening in the consolidated ground, change the earth pressure acting on the lining, and potentially lead to the destruction of the lining. - Therefore, it is necessary to quantitatively investigate the cavities behind the lining in tunnels that have been in existence for a long time. **Product Overview** - Investigations can be conducted from inside small cross-section tunnels. - The penetration rate, thrust, and rod rotation speed of rotary percussion drills and rotary boring machines within the tunnel are measured and recorded, allowing for a quantitative investigation of previously unknown small cavities and the loosening condition of the ground. *Please refer to the leaflet for more information.* **Features** - Collection of detailed N-value data of the ground - N-values can be obtained every 1 cm (compared to 1 m in general geological surveys). - Quick investigation - No need for temporary facilities and no use of core tubes, allowing for a rapid survey. - All-direction investigation - Drilling can be conducted in all directions from inside the tunnel. - Investigation in small-diameter tunnels - Investigations can be conducted in tunnels with a diameter of 2 meters or more. - Investigations from the ground surface are also possible. - Target geology - All types of geology. *For more details, please refer to the technical documentation or contact us.*

Geological survey

Geological survey

We propose survey methods and plans that are suitable for your objectives and current situation in the field of geological surveys. *Over 60 years of experience.

At Kyoa Development Co., Ltd., we propose survey methods and plans that are suited to your objectives and current situation, including simulations and consulting in the field of geological surveys. Our engineers visit the site to observe the topography and geological conditions, starting with "surface geological surveys," and conduct investigations such as "boring surveys" and "in-situ tests." During the surveys and tests, we provide situation reports (interim reports) as needed, and we continuously share information with our clients to facilitate discussions on changes to the survey/test content or additional tests based on the circumstances. 【Features】 ■ Proposing suitable geological survey plans based on over 60 years of experience ■ Guaranteeing highly reliable geological surveys and tests ■ Providing detailed reports for situation understanding and smart progress management *For more details, please refer to the PDF materials or feel free to contact us.

Geological Survey "Surface Geological Survey"

Geological Survey "Surface Geological Survey"

Engineers will observe the topography and geological conditions! We will investigate the characteristics of the ground and bedrock.

At Kōa Development, engineers visit the site to observe the topography and geological conditions, conducting a "surface geological survey" to investigate the characteristics of the ground and bedrock. This survey is conducted to understand the geological properties, engineering properties, and hydraulic characteristics of the foundation ground in the target area, and to estimate and clarify the formation of the topography and geology, as well as the geological structure, based on their planar and spatial distribution. The data from the surface geological survey plays an important role in the interpretation of results from boring surveys and physical exploration. 【Features】 ■ Engineers visit the site to observe the topography and geological conditions ■ Investigation of the characteristics of the ground and bedrock *For more details, please refer to the PDF document or feel free to contact us.

Geological survey "Boring survey"

Geological survey "Boring survey"

We provide all the ground information you need! We investigate the geological layers of the ground using a boring machine.

"Boring surveys" are the most fundamental method of geological investigation. By using a boring machine to excavate and observe the collected samples, the composition of the strata can be understood. Generally, a standard penetration test is conducted during excavation to measure the N value (an indicator of the relative density and hardness of the ground). Our company plans and proposes sampling during boring, as well as various tests and investigations utilizing the borehole, as needed, providing all the ground information required by our customers. 【Features】 ■ Understanding of strata composition ■ Investigation of ground strata composition using a boring machine ■ Provision of all ground information required by customers *For more details, please refer to the PDF document or feel free to contact us.
