Abstract
A method for in situ relocation of an underground utility including the steps of inserting, extending, raising and continuing to raise. The inserting step is carried out by the inserting of at least one lifting member down into the ground alongside the underground utility. The extending step extends a lifting bracket from the at least one lifting member. The raising step raises the lifting member causing the lifting bracket to engage a portion of the underground utility. The continuing step continues to raise the lifting member until the underground utility reaches a predetermined position.
Claims19
A method for in situ relocation of an underground utility, comprising the steps of
- inserting at least one lifting member down into the ground alongside a buried underground utility;
- extending a lifting bracket from the at least one lifting member;
- raising the lifting member causing the lifting bracket to engage a portion of the buried underground utility;
- and
- continuing to raise the lifting member until the buried underground utility reaches a predetermined position.
An underground utility in situ relocation mechanism, comprising
- a beam;
- a lifting device coupled to the beam, the lifting device being positioned on a surface of the ground;
- and
- a plurality of lifting members for insertion down into the ground alongside a buried underground utility, the lifting members being coupled to the beam, each of the lifting members having a lifting bracket that is extensible from the respective lifting member, the lifting bracket engaging a portion of the buried underground utility, the lifting device being configured to apply an upward force on the beam that withdraws the lifting members to some extent from the ground to thereby lift the buried underground utility to a predetermined position.
An underground utility relocation system for use with a lifting device, the system comprising at least one lifting member for insertion down into the ground alongside a buried underground utility, the lifting members being couplable to the lifting device, the lifting member having a lifting bracket that is extensible from the respective lifting member, the lifting bracket being capable of engaging a portion of the buried underground utility, the lifting device being configured to apply an upward force on the lifting member that withdraws the lifting member to some extent from the ground to thereby lift the buried underground utility to a predetermined position.
