Definitions

  • protuberances spread over the surface of the plastic sheet (such a plastic sheet "panel” being patented in U.S. Patent No. 5,167,895).
  • the protuberances can be co-extruded into the sheet, and in the factory or at the site the sheet can be welded into a closed circular shape, and coiled on a spool by bending the deformable circular shape of the extruded sheets flatly toward inside of the circular shape thereof and without elongation to maintain the wall thickness of the circular shape to be used as a thermoplastic liner pipe.
  • the invention also includes apparatus to carry out a grouting process in the installation of the grout through a specially perforated insert tube (or/and multiple tubes) which remains a part of the grouted entity when installation is completed.
  • thermoplastic material as a deforming tube of a flexible nature rather than a deformed pipe known as prior art.
  • temperature at a deforming level for the tube shape change being prior art utilized in constructing "historic time memory,” but a mechanical folding, this would be a part of the "thin wall” method of installation.
  • a temperature constructed "historic time memory” can be utilized in the process of deforming, making the anchor tube a deformed pipe capable of being processed as a reformed product with heat and pressure means.
  • the invention further relates to a method of grouting a re-shaped plastic liner in positions where a radial liner separation from the existing pipe is filled-grouted and where an anchor position is utilized in firmly fixing the liner as a part of the overall composition consisting of the old pipe structure bonded by grout and anchored to a liner structure.
  • a non-bonded grouting with anchored liner can be used for pipe rehabilitation or renovation.
  • WO 93/21399 relates to a system and process for relining channel pipe sections with several hose-like inliners.
  • the internal hose-like inliner of thermoplastic material has on its outside, e.g. a plurality of protuberances as spacers for an external liner (being a "plurality of protuberances" also particular to the invention described in U.S. Patent No.5, 167,895, Dec. 1, 1992 to Agru).
  • the patent application proposes that first a preliner and then an internal inliner externally fitted with protuberances be drawn into the channel to be repaired.
  • a quicksetting mortar is inserted into the annular chamber defined by protuberances and is allowed to set. Fundamental to the overall function of the invention is the space created by the protuberances.
  • PCT/AU86/00362 This known method uses liners of semi-rigid and non-standardly plasticized material, and provides the following steps: forcibly mechanically collapsing (folding) the liner so as to form at least one longitudinally extending depression (fold), fixing a longitudinally extending tearable strap to or about the liner so as to maintain the collapsed configuration, introducing the collapsed liner in its maintained collapsed configuration into the pipe for a desired distance along and within the pipe and releasing the strap in order to restore the tube to its original shape, thus making use of the spring rebounding effect of the liner material.
  • U.S. Patent No. 5,034,180 discloses a method for installing a liner of plastic material in a pipe.
  • the method of this patent uses a thin flexible tubular membrane providing a heat containment tube for insertion into and inflation within an underground conduit to be repaired.
  • the thermally deformed liner is inserted into the tube while hot and flexible.
  • the tubular membrane is pressurized to exclude unwanted fluids from within existing conduit.
  • hot steam is injected into the tube to heat the pipe for its full length externally and internally until it assumes its original circular shape, the liner being thereby expanded against the walls of the pipe, with a flexible tubular membrane therebetween.
  • thermoplastic liner using the material property "historic time memory” relies on this unique property which is then utilized in the reforming process to constitute the pipe within a pipe.
  • the present invention provides a composite lining product, utilizing a thermoplastic sheet with protuberances (one or two sided on a single sheet) made into a tube, capable of being coiled in a flattened form for transportation and installation, folded or deformed into a compact shape with reduced cross section for insertion through an existing pipe, and a method for grouting consisting of the grouting tube (or/and multiple tubes) with perforations and grout application lengthwise at numerous points of the pipe and a method for a grout control lengthwise with internal /external pressure monitors.
  • the present invention allows reforming into a tight fit liner pipe by application of a thermo-pressure process at crystalline temperature, and forming a structural bonded or non-bonded composite liner with a given structure of the existing pipe.
  • the present invention of the plastic liner composite pipe product includes a tubular liner with protuberances (one sided or both sided protuberances) of deformable thermoplastic material, the external diameter of the liner corresponding to internal diameter of the lined pipe (or computed circumference) reduced an amount to compensate for the created annulus resulting from the extended size of the protuberances, to establish a cavity for grouting and providing space for a permanent grouting tube (or/and multiple tubes).
  • Installation of a thin wall liner with protuberances is done by means of utilizing pressure plugs capable of sustaining at least a pressure of 75 psi (,52MPa), which is necessary to provide resistance for the plugs against the internal pressures used in the liner processing and used to counteract the pressures of grouting.
  • the means of closing the ends of the liner by use of rubber plugs can be substituted by an internal restraining spring with a membrane capable of sustaining an same pressures.
  • the water pressurization or air pressurization can be applied for thin liners and where a deformed/reformed type thick wall liner is used a heat/pressure combination is utilized.
  • the thermo-pressure process used in installation can be achieved at a rapid rate of heat permeation and the liner reconstitution in a fit shape can be achieved at the crystalline point.
  • the deformation of the cylindrically shaped tube into a compact shape is a process under controlled deforming temperature of approximately 77 deg. C (for HDPE material, other deforming temperatures for other materials apply accordingly), at which temperature in a continuous movement the deforming rollers force the tube to move into the direction of the deformed formation (the shape of the form being prior art); these rollers have the ability to adjust to a level where a control for the wall separation is secured and pipe fusion is prevented; the above described roller assembly can be augmented with more rollers as case may be for production of the larger sizes.
  • the process can be automated by use of a computerized method or manually adjusted or both.
  • thermoplastic sheets with protuberances by extrusion
  • the welding and putting the sheets into a tubular shape is novel.
  • the continuation of the process to coiling is prior art too. While “U”, “H”, “X”, “W” and “V” shapes are considered prior art the flattened shape was also considered prior art. Exception and distinction must be made for similarity with protuberances utilized for double-containment pipe as prior art. That invention represents fused liners having protuberances necessary for the process of fusion and without benefit of anchoring features as claimed in this patent application.
  • the shapes annotated as prior art were not recognized for the benefits with incorporated protuberances nor were they technically analyzed as such, for a specific benefit that a protuberant feature can be used for anchoring and by sporadic anchor distribution for preventing the liner sheet to resist movements otherwise common to the thermoplastic sheets where installed as liner pipe.
  • the present method is concerned with anchoring the liner, preventing concrete and liner movement, providing a high abrasion resistant surface in contact with a transported fluid, and securing the smooth interior surface in the shape fitting tightly to the given shape of the existing pipe, and maintaining its composite structure resistant to imposed loads from outside and inside the renovated or rehabilitated pipe.
  • the coiling of the liner with protuberances where a thin wall liner is used is related to the mechanical folding action by application of the torque force on the coiling machine and tightly packing the liner tube on the coil.
  • the principles of coiling for a thick wall tube with protuberances has to be done by a method of controlled heat of the material for reason of "historic time memory" of the material.
  • the coiling of the deformed tube with protuberances is specially related to the temperature of the material. There shall be a range of temperatures suitable for coiling from as low as ambient to a temperature of deforming of 77 degrees C, for example in case with HDPE, never to exceed the temperature of crystallinity of the material.
  • the chosen temperature is part of the process of manufacturing and shall be according to criteria set for the anticipated function of the pipe.

  • the prepared wall of an existing pipe, after passing inspection, is lined by a pulled-in liner with protuberances from a coiled position above ground.

  • a shaping arrangement of shieves which provide for the "U” shaping the liner with protuberances prior to its entry into the inlet of the pipeline.
  • the reshaped liner is drastically reduced in cross section of its envelope and easily pulled through the existing pipe in an unconfined manner.
  • the grouting process provides a bond, where required, with the existing pipeline and fills in a controlled manner the cracks and deformities, therefore, repairing the existing pipe, and by anchoring the liner with protuberances into the grout, the structure becomes connected in the pipeline to one another to provide a single unitary stable structure tightly fitting together.
  • the liner with protuberances can be made of suitable plastic material which can be folded or deformed and subsequently returned to its original cross-section, or cross-section adaptable to a given shape of the existing pipeline, either by shape, i.e. , historic time memory properties of the material or by inherent elastic properties of the material.
  • the perforated tube which remains grouted from inside and as such becomes a part of the annulus grouting component, is the continuous pipe sufficiently small to fit the annulus and being provided among protuberances can occupy a position suitable for the spiral, straight line, and other grouting positions.
  • the pressures applied in grouting and annulus pressures are an indirect control providing information about the spread of the grout around the circumference of the pipeline, and when combined with pressure readings for internal reforming of the liner with protuberances represents indications of fullness of the grouting operation, whose objective is to provide a uniform grouting around a total circumference and the total length of a pipeline.
  • the prime application of this liner with protuberances system is in its thin-wall lining composition combined with grouting.
  • the average wall thickness of the liner sheet can range from 3mm to 6mm to 12mm as per design requirements.

  • the ancillary objectives are in lining only the bottom of an existing large size pipe or/and a tunnel structure, where the liner sheets with protuberances used are with fixed ends lengthwise and grouting is done in like manner.
  • Such other ancillary conditions may consist of the spirally wound layers of the liner with protuberances; in a multiple-layered liner structure, grouting is either continuously connected through a spiral arrangement of the liner with protuberances or disconnected grouting layers where one liner is provided inside the other liner in a tubular shape.
  • the liner 20 with protuberances 10 When tightly fit in its reformed state within the pipe, the liner 20 with protuberances 10 may have an exterior (inner) diameter generally corresponding to the internal diameter of the pipe minus twice the height of the size of the protuberance.
  • this sizing may vary depending on the design requirements where more of the grout thickness is required, then the liner size becomes reduced and the result is the contraction of the internal diameter and separation of the protuberances from the wall of the existing pipe.
  • an internal cross section of the lined pipe may be reshaped to a more uniform and, e.g., more circular and smoother curvilinear shape.
  • a pre-liner 30 is used as a separator from the existing pipe 40, and as a grout containment barrier between the existing pipe 40 and the liner 20 with protuberances 10, the pre-liner 30 shall be either inserted prior or at the same time with the liner 20 with protuberances 10.

  • the positive welded connection is established for the sheets with protuberances where one method of fusion-welding is done by overlapping ( Figure 7A) while another method ( Figure 7B) uses a specially pre-manufactured electrofusion locking strip 21, set in the grooved ends and by electric activation of the plastic material at a fusion temperature positive connection is established.
  • This type of fusion eliminates the distortion resulting from overlapping and provides more uniformity to the liner tube 20A.
  • the process of using a set-in locking strip is a manufacturing process done in the factory or a field process done with a portable equipment.
  • the liner with protuberances is open by forced- under-pressure steam, water or air.

  • the liner is only forced into the like positions with the help of unfolding force where it has to be maintained through the completion of the process.
  • the annulus void is pressurized by means of application of grouting into a void-annulus and among the protuberances.
  • the pressures of grouting are associated with the grouting component and only the test pressure with air can be applied in case where annulus shape needs to be compressed against the internal pressure resulting from the liner with protuberances processing.
  • the liner 20 with protuberances 10 fits against the existing pipe 40 or it is expanded to its designed diameter, being under circumferential compression, as in Figure 9.
  • the liner 20 with protuberances 10 having rigidity and stability, is grouted with the pressurization grouting in a sensitive reactive relationship to the internal pressures.
  • the anchoring of the liner 20 with protuberances 10 is finished, the movement of the liner 20 is minimized, and the bonding is established with the existing pipeline 40.

Abstract

Un procédé d'installation dans des tuyaux (40) de gainages en matière plastique (20) dotés de protubérances consiste à former un gainage tubulaire cylindrique (20) pourvu de protubérances en matière plastique d'un diamètre prédéterminé et à le positionner dans une fixation du tuyau existant (40) en appliquant un mortier liquéfié (50). Les protubérances s'étendent radialement à partir du gainage (20) et forment la cavité du mortier. Le gainage (20) pourvu de protubérances est écrasé ou déformé de façon à prendre une forme extrêmement réduite telle que le diamètre global est diminué. Le revêtement (20) à protubérances est introduit dans le tuyau existant (40). La forme cylindrique du gainage (20) à protubérances est ensuite rétablie, les protubérances espaçant le gainage (20) du tuyau existant (40). Le mortier (50) est injecté dans la partie annulaire entre le gainage (20) et le tuyau existant (40), fixant le gainage (20) au tuyau (40).
