No-cut underground flood seal

A cable insertion guide for a sheath for a cable, comprising:

• a sheath insertion portion disposed at a first end of the cable insertion guide;
• a first guide section disposed at a second end of the cable insertion guide, the second end being opposite the first end in an axial direction, the first guide section having a first guide section diameter;
• a second guide section axially disposed between the sheath insertion portion and the first guide section, the second guide section having a second guide section diameter, the second guide section diameter being smaller than the first guide section diameter;
• a guide transition section extending axially between the first guide section and the second guide section so as to transition the first guide section diameter to the second guide section diameter;
• and
• a cable receiving area disposed radially inward of at least the first guide section, the cable receiving area extending between the first guide section and the guide transition section, the cable receiving area comprising a first cable receiving area section disposed radially inward of the first guide section and a second cable receiving area section disposed radially inward of at least part of the guide transition section,
• wherein the first cable receiving area section has a first cable receiving area section diameter and the second cable receiving area section has a second cable receiving area section diameter, and
• wherein the first cable receiving area diameter is larger than the second cable receiving area diameter.

A method of sealing at least one cable, comprising:

• providing at least one sheath, the at least one sheath comprising a sheath cable entrance, a sheath cable exit, a sheath cable passage extending from the sheath cable entrance to the sheath cable exit, and a first sheath section having a first sheath section diameter;
• providing a cable insertion guide having a cable receiving area and a first guide section having a first guide section diameter, the first guide section diameter being larger than the first sheath section diameter;
• inserting the cable insertion guide into the at least one sheath so as to dispose the first guide section within the first sheath section and enlarge the first sheath section diameter;
• placing the at least one cable into contact with the cable receiving area;
• and
• pushing the at least one cable through the sheath cable entrance and into the sheath cable passage,
• wherein the cable insertion guide comprises a cable receiving area disposed radially inward of at least the first guide section,
• wherein the cable receiving area extends between the first guide section and the guide transition section, the cable receiving area comprising a first cable receiving area section disposed radially inward of the first guide section and a second cable receiving area section disposed radially inward of at least part of the guide transition section,
• wherein the first cable receiving area section has a first cable receiving area section diameter and the second cable receiving area section has a second cable receiving area section diameter, and
• wherein the first cable receiving area diameter is larger than the second cable receiving area diameter.
