Emergency construction of a temporary drainage channel using the fabric formwork method "FabriForm"! Solution to the requirement for shortening the construction period! Successful emergency measures! Project Name: Emergency Measures for River Channel Blockage in the Kumano River Nagatono Area - Construction of Temporary Drainage Channel Client Name: Kinki Regional Development Bureau, Ministry of Land, Infrastructure, Transport and Tourism, Kii Mountain Sand Control Office Project Overview At this site, it was necessary to urgently construct a temporary drainage channel to drain the large amount of water that was ponding due to a massive accumulation of sediment blocking the river channel, in order to prevent the occurrence of large-scale debris flow disasters. Our company's fabric formwork method "FabriForm" was adopted for this temporary drainage channel. Immediately after the disaster occurred, there was no route to the river channel blockage site, making it a difficult construction location where workers and construction machinery could not easily approach. The client and the general contractor were very pleased with the outcome.

Fabric formwork for slope protection

This is a concrete mat that constructs high-density, high-strength hardened bodies. "Features" - Labor-saving Based on design drawings, concrete or mortar is injected into mats manufactured in a factory, allowing for construction with fewer people and in a shorter time compared to conventional on-site poured concrete or precast block methods. It also proves effective in disaster recovery. - Cost-effectiveness Since underwater construction is possible, switching and water-stopping work are unnecessary, resulting in shortened construction periods and excellent economic benefits.
