A method and apparatus provides an enclosed pipe repair where two pipe segments extend through first and second ends of the enclosure to a volume in the enclosure housing the repair. The enclosure surrounds the repair to hopefully prevent roots from accessing the repair in many cases, and if a second problem exists, to provide access to the site of the repair through a lid in the enclosure.

The invention relates to a system (10) for curing and/or inspecting a pipeline lining (30) positioned in a pipeline (20), the pipeline lining (30) comprising an outer plastics material layer and an inner fiber composite layer, the fiber composite layer comprising a plastics material which is to be cured and/or which is at least partially cured. In accordance with the invention, the system (10) comprises at least one high-frequency unit (40) which comprises at least one microwave-generator unit (41) and at least one microwave-transmitting antenna (42) for curing a plastics material which is to be cured, at least the at least one microwave-transmitting antenna (42) being movable in the pipeline (20) by means of a transporting device (60).

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.

Methods and systems for treating emissions during a cured-in-place pipe (CIPP) closed molding process in which a resin-impregnated fibrous material is placed within an existing fluid conduit and cured in situ to seal an opening in the conduit. Such a method includes capturing multi-phase emissions released by a resin-impregnated fibrous material during curing thereof in a CIPP process, accumulating the multi-phase emissions, condensing at least a water portion of the multi-phase emissions, and treating vapor constituents of the multi-phase emissions.

An absolute coordinate acquisition method is an absolute coordinate acquisition method for acquiring absolute coordinates of an underground pipeline, the method including: a marking step S101 of setting a plurality of reference points on a road surface and setting a measurement point on a pipeline installed inside an excavated ditch; a measurement step S102 of measuring absolute coordinates of the reference points; a relative position calculation step (S103 to S105) of calculating relative positions of the reference points and the measurement point to a reference position; and an absolute coordinate calculation step S106 of calculating absolute coordinates of the measurement point based on the absolute coordinates of the reference points and the relative positions of the reference points and the measurement point.

A spiral pipe-forming apparatus includes a non-circular guide portion which is rotatable with respect to an apparatus frame around a rotary axis. The non-circular guide portion is configured to be applied to a peripheral surface of a preceding spiral pipe portion. An acting portion is configured to act such that the non-circular guide portion follows a peripheral surface of an existing pipe.

A rodent deterrent system for a pipe system, the pipe system including a T-junction and a midsection riser. The deterrent system for the T-junction includes a first mesh screen configured to surround a vertical portion of the T-junction and a second mesh screen configured to surround a horizontal portion of the T-junction. Also, the deterrent system for a perforated riser includes a mesh wrap sleeve configured to surround the midsection of the riser. Alternatively, the riser midsection sleeve can be lengthened so that the second mesh is not needed as the lengthened sleeve also performs the same function as the second screen.

An apparatus and method for laying pipe in a ditch. The apparatus comprises a mobile platform having a longitudinal central axis. A support extends from the mobile platform and includes a cradle. The cradle supports a weight of a pipe segment in alignment with the central longitudinal axis of the mobile platform as the pipe laying apparatus transports the pipe segment to a location where the pipe segment is to be placed and as the pipe laying apparatus offloads the pipe segment at the location where the pipe segment is to be placed in the ditch.
