Abstract

An elongated flexible tube structure is provided defining a plurality of individual passages extending longitudinally therethrough. The passages include an air vent passage, a suction passage and a fluid injection passage and the passages include first end portions opening separately outwardly of one end portion of the tube structure. The other end portion of the tube structure defines an outer tubular jacket enclosing and defining the second end portion of the air vent passage. The second end portion of the injection and suction passages are defined by separate tube sections disposed in and extending longitudinally of the tubular jacket. The end of the tubular jacket remote from the aforementioned one end portion thereof has the corresponding end of the suction tube section anchored therein and the latter includes lateral suction openings formed therein opening outwardly into the interior of the tubular jacket. The tubular jacket includes longitudinally spaced lateral air vent openings formed therein and the fluid passage tube section includes a flexible free end portion extending outwardly through one of the air vent openings. Also, a longitudinal midportion of the tube structure includes an outer inflatable bladder surrounding the tube structure and an inflation passage extending longitudinally of the tube structure having a first end opening into the interior of the bladder and a second end opening outwardly of the aforementioned one end of the tube.

Claims

1. A combined sump drainage and irrigation device including an elongated flexible tube structure defining a pair of side-by-side large diameter individual suction and vent passages and pair of small diameter individual inflation and injection passages disposed on remote sides of adjacent portions of said large diameter passages, an inflatable elongated balloon bladder surrounding said tube structure centrally intermediate its opposite ends, extending longitudinally thereof and sealed at its opposite ends to longitudinally spaced portions of said tube structure, one set of ends of said large diameter passages and one of said small diameter passages opening separately outwardly of one end portion of said tube structure, the other end of one of said small diameter passages opening outwardly into the interior of said bladder, said tube structure including a tubular jacket enclosing the other end portion of said tube structure and having a first end adjacent said bladder sealed relative to the outer surfaces of said tube structure and an end wall closing the second end of said jacket remote from said bladder, the other end of said vent passage terminating a spaced distance from said end wall and opening into the interior of said jacket, said other end of said suction passage opening into one end of a tube section disposed in and extending centrally longitudinally of said jacket and having its other end anchored to and closed by said end wall, said jacket including longitudinally spaced lateral air vent openings formed therein intermediate said end wall and said first end of said jacket, said tube section other end including lateral openings formed therein spaced from but adjacent said end wall, the other end of said injection passage opening into one end portion of a second flexible tube section loosely received in and extending longitudinally of said jacket and having its other end portion directed outwardly through one of said air vent openings and extending outwardly beyond said one air vent opening.

2. The device of claim 1 wherein said one end of said inflation passage opens separately outwardly of said tube structure intermediate said bladder and said one set of ends of said large diameter passages.

3. The device of claim 1 wherein said one set of ends of said large diameter passages and corresponding end of the other small diameter passage include adapter end portions thereon for removable connection to a vent discharge assembly, a source of vacuum and a source of injection fluid under pressure.

4. The device of claim 1 wherein said inflatable bladder tapers toward said one end portion of said tube structure.
