Soil Contamination Investigation "Detailed Survey"

Soil Contamination Investigation "Detailed Survey"

Investigation to be conducted as the next step of the overview survey! Mainly focusing on the investigation of the depth of contamination.

At Kyoa Development, we conduct a "Detailed Survey" as the next step following the overview investigation. The "Detailed Survey" is a depth investigation of contamination conducted when soil pollution is confirmed (when specific harmful substances exceed the standard values). Since the investigation methods vary depending on the depth of the contamination source and the soil and geological conditions, these tasks require a wide range of specialized knowledge and know-how. Our company continuously provides education and training for the technicians engaged in these tasks, ensuring that we deliver speedy and highly accurate investigation results. 【Features】 ■ Environmental survey drilling machine (Eco Machine) - Generates minimal excavation waste, resulting in less contaminated soil to store and process - Fast excavation speed and easy machine mobility - Capable of drilling up to 20-30 meters ■ We provide speedy and highly accurate investigation results *For more details, please refer to the PDF materials or feel free to contact us.

Soil contamination survey "Certified Survey"

Soil contamination survey "Certified Survey"

We will conduct an investigation to obtain certification of compliance with standards for the land designated by the region!

At Kyoa Development, we conduct "certification surveys" to obtain certification for land designated in specific areas. The density and methods of the survey vary depending on factors such as the depth of contamination and the condition of fill brought in from outside. Soil at depths where contamination has been confirmed cannot receive certification. There are two types of survey methods: pre-excavation surveys and post-excavation surveys. These tasks require a wide range of specialized knowledge and know-how. Our company continuously provides education and training for the technicians engaged in these tasks, ensuring that we deliver speedy and highly accurate survey results. 【Features】 ■ Environmental survey drilling machine (Eco Machine) - Capable of soil sampling without using excavation water by applying vibration and rotation to the cutting edge - Minimal excavation residue, resulting in less contaminated soil to store and process - Fast excavation speed and easy machine mobility ■ Providing speedy and highly accurate survey results *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 observe the terrain and geological conditions! We will investigate the properties of the ground and bedrock.

At Kyoa 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, from 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 explorations. [Features] ■ Engineers visit the site to observe the topography and geological conditions ■ Investigate 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 soil layer composition and more using a boring machine.

"Boring investigation" is the most fundamental method of geological survey. 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 various tests and surveys using the borehole, as well as sampling when necessary during boring, providing all the ground information required by our clients. [Features] - Understanding of strata composition - Investigation of ground strata composition using a boring machine - Providing all the ground information required by clients *For more details, please refer to the PDF document or feel free to contact us.

Fiber scope investigation

Fiber scope investigation

You can check the current condition inside the underground tank and identify issues or conduct investigations.

By inserting a fiberscope from the top of the tank and checking the internal condition, it is possible to detect the presence of foreign objects, corrosion, welding defects, and other issues. 【Problems Due to Aging】 Steel single-shell tanks buried underground can experience corrosion over 20 to 30 years, depending on the surrounding environment, leading to a rapidly increasing risk of hazardous material leakage. 【Investigation for Current Condition Assessment】 The current condition of the underground tank will be investigated using a fiberscope. It is not uncommon for the interiors of aging tanks to show significant rust and corrosion. —What can be understood through a combination of airtightness testing and fiberscope inspection— ● The condition of foreign objects and deposits inside the tank and piping ● The presence and condition of corrosion and pitting inside the tank and piping ● The integrity status of welding defects at piping joints *For more details, please contact us or download the PDF materials for review.

Investigation of simulation techniques for the dynamics between soft bodies and rigid bodies.

Investigation of simulation techniques for the dynamics between soft bodies and rigid bodies.

[Aizu University Joint Research] Creating a 3D flexible model to achieve simulations close to reality!

Our company is conducting technical research and investigation to model three-dimensional flexible objects using the physics engine 'AGX Dynamics' on the simulator "Choreonoid," enabling multi-body simulations with rigid body models. In the fiscal year 2019, we created this three-dimensional flexible object model, and we have achieved research results that improve gripping force by using gel grippers (finger caps) on robotic hands. To reproduce similar simulations on Choreonoid, we reconstructed the three-dimensional flexible object model into a gel gripper shape and realized it. Choreonoid homepage: https://choreonoid.org/ja/index.html ■ Features - Reproduction of three-dimensional flexible object models on Choreonoid ■ Basic Functions - Simulation of three-dimensional flexible object models *For more details, please contact us.

Water Cleaning Robot: Cleaning and Inspection of Distribution Reservoirs and Water Purification Tanks

Water Cleaning Robot: Cleaning and Inspection of Distribution Reservoirs and Water Purification Tanks

Contributing to society through "clean water"! You can capture the situation as an image.

Our company conducts cleaning and inspection of water distribution reservoirs and water purification tanks using "underwater cleaning robots." Previously, internal inspections and bottom cleaning of water distribution reservoirs and water purification tanks could only be done by either draining the water or using divers. Draining the water results in wasting precious drinking water and involves dangerous work (such as the risk of oxygen deficiency) within the tanks. Additionally, work performed by divers poses hygiene concerns and risks, as humans enter the drinking water. To eliminate these dangers, our company performs cleaning operations using robotic technology, ensuring safety in our approach. 【Features】 - Cleaning can be performed while maintaining normal water supply without draining the water from the distribution reservoirs or purification tanks. - Inspections of the interiors of distribution reservoirs and purification tanks, which are usually inaccessible, can be conducted, and the conditions can be documented with images. - There is no need for the time and cost associated with draining water for cleaning or inspection, nor for refilling the tanks afterward. - Cleaning and inspections can be carried out without personnel entering the interiors of the distribution reservoirs or purification tanks, ensuring safety from a hygiene perspective and reducing the risks associated with the work. *For more details, please refer to the PDF document or feel free to contact us.*
