Arai Gumi Co., Ltd. (Headquarters: Nishinomiya City, Hyogo Prefecture; Representative Director: Kimmatsu Baba; hereinafter "the Company") has conducted a drone inspection demonstration targeting the inflow and outflow sections of the Yaenosato rainwater storage facility in Higashiosaka City, areas where it is difficult for people to enter. This experiment aims to establish a new inspection method to improve the safety and efficiency of infrastructure maintenance in Higashiosaka City.
1. Necessity and Challenges of the Demonstration Experiment
Generally, storage facilities often have complex structures to control the inflow and outflow of rainwater and sewage. These facilities are prone to cracking and corrosion of internal structures due to aging, making regular inspections essential.
However, due to their structures, these facilities face the following challenges:
- Physical difficulty of human inspection: It is difficult for a person to enter and inspect places with narrow internal spaces. Also, tall structures require the installation of scaffolding for investigation.
- Increased risk: Inaccessibility delays the discovery of deterioration, raising concerns of sudden accidents or malfunctions.
2. Overview of the Demonstration and Innovative Technology
In this demonstration, inspection work was carried out using the narrow-space inspection drone "IBIS2" manufactured by Liberaware Co., Ltd.
[Experiment Overview]
- Location: Inflow and outflow sections of Yaenosato rainwater storage facility, Higashiosaka City
- Period: November 28, 2025 (Friday)
- Equipment used: Narrow-space inspection drone "IBIS2" manufactured by Liberaware Co., Ltd.
- Verification items:
- Confirmation of stable flight capability in narrow and complex structures
- Performance confirmation of lighting and ultra-high-resolution cameras capable of clear shooting even in dark places
- Shortening of inspection period and labor-saving effects compared to conventional inspection methods
3. Results of the Demonstration Experiment
As a result of this demonstration, the narrow-space inspection drone "IBIS2" succeeded in penetrating deep into structures with narrow spaces and clearly capturing the internal structure and the condition of the facility.
In particular, the following results were confirmed:
1. Ensuring Safety and Mitigating Risks: By saving labor in inspection work and eliminating the need for workers to enter dangerous environments, the risk of personal injury was mitigated.
2. Innovation in Utilizing Deterioration Diagnosis Data: By accumulating still images and video data captured by drones, it becomes possible to confirm the progression of structural deterioration with data, enabling the formulation of maintenance and repair plans with a long-term perspective.
