Abstract

The present invention provides an apparatus and method for stabilizing a joint between two sections of corrugated pipe. A first section of corrugated pipe is associated with a second section to form a joint. One flexible member with two ends is looped around the first section of pipe, secured against a corrugation, and the two ends are associated and tightened. A section of the flexible member is left as a tail. A second flexible member is installed the same way on the second section of pipe, again with a section left as a tail. Each tail is then stretched across the joint, threaded between the other flexible member and pipe, brought back across the joint, and cinched forming two axially aligned supports secured against a corrugation, such that two axially aligned support are formed.

Dependent claims

A corrugated pipe connection stabilizing apparatus comprising;

a) a first flexible member and a second flexible member each comprising a first end and a second end;
b) a first corrugated pipe section comprising a circumference, an axis, an outer surface with at least one corrugation, and a female end;
c) a second corrugated pipe section comprising a circumference, an axis, an outer surface with at least one corrugation, and a male end associated with said female end of said first corrugated pipe section creating a joint;
d) said first flexible member further comprising means for associating said first end with said second end of said first flexible member and for tightening said first flexible member circumferentially around said first corrugated pipe section against said at least one corrugation leaving an unrestrained first tail portion;
e) said second flexible member further comprising means for associating said first end of the second flexible member with said second end of said second flexible member and for tightening said second flexible member circumferentially around said second corrugated pipe section against said at least one corrugation leaving an unrestrained second tail portion;
f) said first end of said first flexible member further comprising means for cinching said first tail portion to said first end of said first flexible member for forming a first axially aligned support across said joint;
g) said first axially aligned support comprising said first segment of said first tail portion of said first flexible member stretched across said joint, said tail portion threaded between said second flexible member and said second corrugated pipe section, stretched back across said joint and secured by said means for cinching said first tail portion of said first flexible member to said first end of said first flexible member.

4 more elements

A method for stabilizing a corrugated pipe connection prior to burying said connection comprising:

a) a first step wherein a female end of a first corrugated pipe section comprising at least one corrugation on an outside surface and a first circumference, and a male end of a second corrugated pipe section comprising at least one corrugation on an outside surface and a second circumference are associated creating a joint;
b) a second step wherein a first strap member comprising a first end and a second end is looped around the circumference of said first corrugated pipe section against said at least one corrugation on said outside surface of said first corrugated pipe section and tightened using means associated with said first end for connecting said first end to said second end of said first strap member leaving a first tail portion;
c) a third step wherein a second strap member comprising a first end and a second end is looped around the circumference of said second corrugated pipe section against said at least one corrugation on said outside surface of said second corrugated pipe section and tightened using means associated with said first end for connecting said first end to said second end of said second strap member leaving a second tail portion;
d) a fourth step comprising forming a first axially aligned support wherein said support is created across said joint by stretching a first segment of said first tail portion of said first strap member across said joint, threading said first tail portion between said second strap member and said second corrugated pipe section, stretching said first tail portion back across said joint and using means for cinching said first tail portion of said first flexible member to said first end of said first flexible member to hold said first corrugated pipe section in position relative to said second corrugated pipe section.
