Summary:
|
Underground facilities such as tunnels, maintenance hole and handhole are deteriorating. For example, cracks and water leakages occur and these phenomena degrade the safety and serviceability of the underground facilities. If the deterioration is neglected, large-scale repair and reinforcement measures will probably be required, which will further increase the cost in the future. Therefore, it is highly recommended that periodic inspection and timely maintenance would be performed.
Safety management of telecommunication infrastructure facilities is generally described in ITU-T Recommendation L.330, but the detail technologies and countermeasures for each facilities leaves for other Recommendations.
This Recommendation describes the inspection procedures, technologies and countermeasures for maintenance of underground facilities defined in L.330.
