A system for the repair or reinforcement of a pipeline includes a casing having a dimension to envelope a damaged portion of the pipeline, such that a space is defined between an inner surface of the casing and an outer periphery of the pipeline. An injection port is positioned along the casing and is in selective communication with the space. A cap assembly is frictionally attached to the casing and the pipeline, after which time an injectable material is selectively injected through the injection port until filling a substantial entirety of the space.

A clamp for repair of a pipe coupling, includes a clamp unit including a side wall with an inner surface, the inner surface having a curvature dimensioned to match an outer curvature of a pipe coupling to be repaired. A coupling on the clamp unit is constructed and arranged to couple a first portion of the clamp unit with a second portion of the clamp unit. The coupling, when secured, operates to induce a radially inward force on the inner surface of the clamp unit. A window is formed as an opening in the side wall of the clamp unit. The window is dimensioned to expose a flange of a pipe coupling to be repaired.

Trenchless methods for forming a curved hole channel with a steel sleeve and pipeline lifting are provided, including steps of: (T1) drilling a straight hole channel, and inserting the steel sleeve into the straight hole channel; (T2) inserting a guiding pipe into the steel sleeve, and determining a bending direction of a hole channel to be formed; and (T3) inserting a flexible steel-wire pipe into the guiding pipe, and punching to form the curved hole channel. With applying the creative trenchless method for forming the curved hole channel, a specially-made grouting pipe is accurately inserted to a bottom of a subsiding pipeline section, so that a polymer material is conveniently injected to a bottom of a disease position. Though utilizing an expansion force generated by the polymer material, the subsiding pipeline section is uplifted, so as to realize trenchless repairing.

A method and apparatus for connecting pipe sections or repairing two separated pipe sections is provided, including for extruded chopped filament pipe (“ECFP”). An apparatus having a sealable connecting jacket is provided, which includes a mold configured to fit around a cut section of ECFP and receive a resin or other material through an input, and a curing system, such as a hot water intake surrounding the mold to heat and cure the resin forming the new pipe section.
