About This Product

■Summary

``Kukei Channel'', a rectangular cross-section waterway for side gutters that makes it possible to reduce the height of drainage pipes, was developed for use in side gutters such as BOX tunnels. Roads built underground are divided into a space for vehicles to pass through and a lower part of the road surface where road drainage ditches, etc. are installed. When planning underground structures such as tunnels, the most important factor in determining the depth below the road surface is the height of the road drainage structure. The "Kukei Channel" maintains the same performance as conventional drainage channels in both the channel and the basin, while significantly reducing the height, thereby reducing the excavation depth of the underground structure and reducing the size of the underground structure itself. Therefore, the overall construction cost can be reduced. In long tunnels, a lifeguard road is installed at the back of the gutter, but for the "straitway with a vertical wall of the lifeguard passageway", concrete paving using the slip form construction method is used to construct a safe, economical structure in a short period of time. can.

■Features

1. Design conditions The design load corresponds to the T-25 longitudinal wheel load. In addition, it complies with the Ministry of Land, Infrastructure, Transport and Tourism Kinki Regional Development Bureau Design Handbook Volume 3 Road Edition. (*Construction load (finisher, etc.) is also taken into account) 2, Economical The "Kukei Channel" is more than 30% lower in height than a circular channel or an open channel with a lid (our comparison), making it possible to make the bottom surface shallower when used in side ditches such as cut-and-cut tunnels. Significant labor cost savings can be achieved. 3. Lineup ``Kukei Channel'' is available in three types: a basic type, a type with legs, and a type with a vertical wall for the lifeguard passageway.

■Basic type Patent No. 4112553

BOX Effective for tunnels and side ditches of crossing boxes.

■Legs type: Patent No. 4112553

This is effective when there is seepage water in the BOX tunnel.

■Watchman passage with vertical wall type: Patent No. 4618740

A wall attached to the canal can be used as a passage for lifeguards. Also, since it is an integrated type, it can contribute to shortening the construction period. 4, drainage Sufficient drainage capacity of the road surface drainage spouts has been confirmed through drainage experiments. 5, Maintenance Separate spouts with sufficient drainage capacity are installed at regular intervals to prevent large debris from falling, and can be expected to improve the efficiency of cleaning work with high-pressure cleaning vehicles.
