    摘要: A plastic profiled strip (10) is provided for producing helically wound tubes or pipes, the strip (10) having female and male joint formations (13, 14) extending along opposite longitudinal margins thereof and arranged so that upon spirally winding the strip into a tubular form, the joint formations (13, 14) can be interlocked to thereby lock adjacent windings of the strip together, the male joint formation (14) comprising a hinged flap (15) which is flexibly connected to the strip (10) for hinging movement between a disengaged or unlocked position displaced from the plane of the strip (10) and a locking position wherein it interlocks with the female joint formation (13) of an adjacent winding of the strip (10).

    摘要: A composite strip 10 windable to form a helical pipe is disclosed. The composite strip 10 comprises: an elongate plastic strip 11 having a base portion 12 and at least one lengthwise extending rib portion 20 upstanding from the base portion 12; and an elongate reinforcing strip 30 extending lengthwise and supported laterally by the rib portion 20, the reinforcing strip 30 having a height to thickness ratio of at least three to one and orientated substantially perpendicular to the base portion 12. When wound into a helical pipe, the reinforcing strip 30 reinforces the pipe against radial crushing loads. A bead 40 seals the reinforcing strip 30 from the environment. Desirably the composite strip 10 further comprises: a planar lamina 50 extending lengthwise and bonded to the base portion 12, the lamina 50 having a higher Young's modulus and strength than those of the plastic strip 11. The lamina 50 greatly improves the pressure rating of a pipe wound from the strip 10.

    摘要: A method of rehabilitating underground pipes which comprises the steps of: (a) forming a liner pipe (5) by winding a strip (4) made of a synthetic resin into a helical shape so that the side edges of the convolutions of the wound strip (4) are interengaged with each other; (b) continuously introducing the liner pipe (5) into an underground pipe (1) while the liner pipe (5) is being advanced inside the underground pipe (1); inserting a slip restraining member in the form of a wire rod (6) continuously to the interconnected edges of the convolutions of the said strip (4), and then removing the said strip (4) when the diameter of said liner pipe (5) is to be increased at the same rate as said strip (4) for forming said helical liner pipe (5) is conveyed.

    摘要: A method for protecting conduits in which a tube produced by helically winding a strip and interconnecting the edges of the strip to allow longitudinal slip is placed adjacent the area to be lined or overlapped. The tube is held at a selected diameter during placement and a winding force is applied by expander means driven along the tube to cause the interconnected edges to slip progressively change the diameter of the tube to engage the conduit. The progressive change may be caused by continuing the step of winding.

    摘要: A method is disclosed for winding a composite strip onto a spool having a hub in which the strip includes a plurality of laterally spaced apart lengthwise extending rib portions upstanding from the base portion. The method comprises the steps of feeding the strip towards the hub of the spool; driving the fed strip through a roller set so as to plastically deform the strip to give it a curved base portion; and winding the deformed strip onto the hub to form spooled strip, the winding creating tension in the strip. The plastic deformation of the strip through the roller set substantially reduces the tension in the strip that would otherwise occur.

    摘要: An hydraulic control arrangement (66) in association with a pipe relining machine Includes fluid pressure supply and return lines (32, 33), a motor controller (80) to control a motor (67) and a radial position controller. The radial position controller supplies fluid under pressure to a radial positioning arrangement (46) to set diameter of a relined pipe. The radial position controller has a first normally closed valve (83) supplying fluid under pressure to the radial positioning arrangement (46) and a second normally open valve (84) allowing fluid to be withdrawn from the radial positioning arrangement (46). The arrangement (66) allows the pipe relining machine to be withdrawn in the event of a failure.
