A fluid conduit ramp construction provides partitions within a low profile outer conduit to reduce weight and increase strength while having a reduced device pressure loss at high flow rates such as are required for fire-fighting circumstances where large quantities of water must be supplied across a road or thoroughfare. The fluid conduit ramp may be rigid or flexible and of sufficient width to unconditionally provide fluid conduit cross-sectional areas larger than the nominal diameter of fire hose with which it is used. The fluid conduit ramp can be quickly deployed by one or two persons requiring only a short duration of traffic interruption after which traffic flow may be resumed at higher speeds than are possible using hose bridges.

Described herein is a fire containment connector. It includes a female end to connect with a male coupling on a first fire hose and a male end to connect with a female coupling on a second fire hose. The fire containment connector also includes a cylindrical base that routes water from the first fire hose to the second fire hose. A cylindrical section of a sleeve rotates about a main body of the cylindrical base until the fire containment connector is in an open position. An oblong opening in the main body allows water to exit the cylindrical base and enter a hollow protuberance of the sleeve when the oblong opening and the hollow protuberance are aligned. A curved slit in the hollow protuberance expels a fan-shaped spray of water and a wall of water is formed.
