Abstract (en)
[origin: US4722479A] An injection hose for construction joints in concrete structures includes an essentially liquid-impermeable base structure of flexible material such as rubber or synthetic material and defining a passage duct. The base structure has along its length radial openings for the escape of injection liquid from the passage duct and, along its length in the area of the radial openings, at least one longitudinal depression for receiving a strip of a material which is compressible under the pressure of the injection liquid and which covers the openings. A hose of liquid-permeable material surrounds the base structure and strip. A plurality of radial openings are provided in the base structure, and the associated depressions and strips are distributed around the circumference of the base structure angularly symmetrically in relation to the central longitudinal axis.
