Technical Document: Oil Pollution Control Technology for a Decarbonized Society

Technical Document: Oil Pollution Control Technology for a Decarbonized Society

A Japanese-origin activated carbon purification method for a decarbonized society! Addressing oil contamination with the Smart Cap method, an activated carbon purification technology!

[New Oil Pollution Control Technology for a Decarbonized Society] ■ Following the Japanese government's "2050 Carbon Neutral (CN2050)" initiative in 2020, there has been a transformation in corporate awareness towards a decarbonized society. ■ The social implementation of a unique and highly effective "Negative Emission (NE) technology" that stores "biochar" in the ground and agricultural land, strongly promoting CN2050, has begun. ■ Since the postponement of establishing soil oil pollution concentration standards in the past, Japan's development of oil pollution purification technology has been in decline, peaking 20 years ago. ■ The "Activated Carbon Bioremediation Technology," which is also an NE technology, progresses with bioremediation after the sensory values of oil pollution are cleared early on. As a result, the challenge of determining the endpoint of purification, which was difficult with bioremediation, has been overcome, transforming it into a technology with excellent reliability for site management. ■ In Japan, there is a similar activated carbon purification technology known as the "Smart Cap" method, which has been proven to be applicable to oil pollution control as VOC purification technology. *For more details, please contact us or view the PDF download.

Non-destructive testing: Visible image method for crack investigation

Non-destructive testing: Visible image method for crack investigation

Automatically extract "crack width" and "crack length"! No need to set up scaffolding for inspection!

Visible cracks and the occurrence of bulging are the first steps of deterioration and deformation. The digital imaging method automatically extracts crack width and length, and CAD output is also possible. Cracks are automatically extracted from the captured digital images. It can automatically extract "crack width" and "crack length." Since crack extraction is analyzed from the captured images, there is no need to set up scaffolding for inspection as long as the shooting location can be secured. 【Advantages】 ■ Safety (non-contact): Diagnosis can be performed from a safe location. ■ Record: Deterioration conditions can be visualized with thermal images, and image data can be saved for analysis. ■ Economic (short time): No need for temporary structures such as scaffolding or gondolas. *For more details, please contact us.

Line drone

Line drone

New Standards for Safe Drone Operations

The use of drones for exterior wall inspections and infrared surveys is gaining attention as an efficient method that allows for inspections without the need for scaffolding. However, there is always a risk of crashes due to problems during flight, which poses a significant challenge for on-site safety managers. To thoroughly mitigate this risk, our company has implemented the "Line Drone" system. By using a dedicated line for the drone, we achieve a fail-safe mechanism that physically controls the flight range in the event of loss of control or runaway. ■ Benefits for Safety Managers - Provides peace of mind on-site: Instead of relying solely on software or sensors, we physically control the drone to minimize impact on people and the environment. - Improved efficiency and reliability of inspections: Safety measures allow for a smooth inspection flow, enabling you to trust the process. - Significant reduction in accident risks: Prevents unintended behaviors that could lead to runaway or crashes, enhancing on-site reliability and compliance with safety standards. We actively utilize the Line Drone to balance "efficiency of inspections" and "safety on-site." We prioritize safety management and provide reliable inspection services. *The Line Drone is a system developed by Seibu Construction Co., Ltd. and MAC Co., Ltd.

【Services for Existing Structures】Exterior Wall Inspection

【Services for Existing Structures】Exterior Wall Inspection

Investigation of tile and mortar peeling, lifting, cracking, etc.! Introducing the exterior wall inspection conducted by our company.

Even in durable reinforced concrete buildings, natural environmental factors such as daily wind, rain, light, and heat, as well as human usage conditions, can lead to aging and deterioration of the material's strength and performance over time. Therefore, our company conducts exterior wall surveys to gather basic data for repair work and to understand the current condition of the exterior walls. Using a tapping hammer, we tap the wall surface to check for any detachment based on the sound produced. In crack surveys, we measure the width and length of cracks using a crack scale. Additionally, we can investigate wall detachment using infrared thermography, which can be used in conjunction with tapping surveys. [Survey Items] - Detachment, bulging, and cracking of tiles and mortar - Deterioration of sealing and finishing materials *For more details, please refer to the related link page or feel free to contact us.

[Services for Existing Structures] Post-Fire Investigation

[Services for Existing Structures] Post-Fire Investigation

Conducting a more accurate survey! It is also possible to investigate the estimation of the tensile strength of steel materials and the measurement of bolt axial force.

In the case of fire-resistant structures such as reinforced concrete and steel structures, most instances do not develop into large-scale fires even if a fire occurs, thus avoiding destruction. Therefore, it is necessary to accurately assess the structural safety and durability of the remaining structures for safe reuse after a fire. As guidelines for such post-fire investigations, the Architectural Institute of Japan has published "Guidelines for Fire Damage Diagnosis and Repair/Strengthening Methods, and Commentary," and the Japan Society of Civil Engineers has published "Guidelines for Diagnosis and Repair of Steel Bridges Affected by Fire." At Just, we conduct more precise investigations by incorporating our own non-destructive testing methods in accordance with these guidelines. Additionally, by applying non-destructive testing technology, it is also possible to estimate the tensile strength of steel materials and measure bolt axial forces on-site without damaging the components. Please feel free to contact us if you require our services. *For more details, please refer to the related links page or feel free to reach out to us.

Seismic Survey for Existing Structures

Seismic Survey for Existing Structures

We conduct preliminary surveys, first-stage surveys, and detailed surveys! Introducing our services for existing structures.

We would like to introduce our service "Seismic Survey" for existing structures. The survey for seismic diagnosis of existing RC (Reinforced Concrete) and SRC (Steel Reinforced Concrete) buildings is conducted in accordance with the "Standards and Explanations for Seismic Diagnosis of Existing Reinforced Concrete Buildings." Starting with a preliminary survey to determine the applicability of the diagnostic standards and set the diagnostic level, we conduct primary surveys, detailed surveys, and more. The investigation of components, seismic walls, and the position and dimensions of openings is carried out meticulously, as these factors significantly impact the diagnostic results. In addition, we also conduct surveys for seismic diagnosis of steel structures and wooden houses. Please contact us if you require our services. 【Overview of Seismic Survey】 ■ Survey for seismic diagnosis of existing RC and SRC buildings ■ Survey for seismic diagnosis of steel structures ■ Wooden house diagnosis *For more details, please refer to the related link page or feel free to contact us.

"Soil Contamination Survey" [Soil Overview Survey / Soil Detailed Survey]

We will plan accurate research with the aim of ensuring smooth circulation of real estate!

The soil contamination survey consists of a general survey (Phase 2) to understand the horizontal extent of contamination, and if contamination is found, a detailed survey (Phase 3) to determine the vertical extent of contamination, allowing us to grasp the presence or absence of contamination and the overall picture. 【Features】 ■ Extensive track record nationwide ■ Conducted both administrative response surveys and voluntary surveys across the country ■ Rich experience in conducting surveys at operational factory sites where technical skills and judgment are required ■ Proposing the minimum necessary survey plan to understand risks *For more details, please refer to the PDF materials or feel free to contact us.
