Abstract
The utility model discloses a lining hose for cured-in-place trenchless underground pipe rehabilitation, which comprises a cylindrical casing, an outer composite hose, and a three-layer composite connected piece including a TPU (thermoplastic polyurethane) membrane, a fiberglass mesh and a reinforced polyester knitted felt. The fiberglass mesh (for reinforcing) is arranged on the surface of the reinforced polyester knitted felt by means of mechanical needling, the TPU membrane is formed by extruding and casting TPU particles via an extruder and is composited to the face of the fiberglass mesh with the reinforced polyester knitted felt, thereby effect of firmer adhesion is achieved, no adhesive is contained, once forming is achieved, the best effect of engineering operation can be achieved and completed eventually, characteristics of TPU materials are fully utilized, and hoses with different calibers are made by the aid of upper and lower joint pressure strips according to different operation pipes. An inner polyester knitted felt hose is made of single polyester knitted felts in butt joint via joints, and the diameter of the inner polyester knitted felt hose is larger than that of the outer composite hose.
Description
Technical field
The utility model relates to multiple under ground piping CIPP (Cured In Place Pipe) inversion method reparation liner hose.
Background technique
CIPP (Cured In Place Pipe) inversion method technology is a kind of under ground piping non-excavation repairing technique of novelty, and this technology is invented by the Britain technician in twentieth century the seventies, imports economic hair side country such as the Europe and the U.S. subsequently into.It becomes countries in the world with its unique process engineering and outstanding technical advantage and uses maximum a kind of internal lining pipe restorative procedures.And at present domestic inverted liner pipeline non-excavation repairing technique is new the introduction, all operations with the liner hose material based on full import.Based on the problems referred to above, I have designed this CIPP (Cured In Place Pipe) inversion method under ground piping and have repaired liner hose.
The model utility content
The purpose of this utility model is to provide a kind of liner hose for CIPP (Cured In Place Pipe) the non-trenchless rehabilitation under ground piping of inversion method; solve one: all materials of existing engineer operation unit are from external import; thereby reduce engineering cost, to shorten the purchasing of raw materials greatly long receipt period; can make the non-excavating underground pipe line recovery technique be widely used at home, from the angle of protection environment, overall social benefit and good in economic efficiency.Solve two: the PE film of the more domestic domestic production of units defective of fitting at present, the optimum efficiency that pipe plays in finally can not bringing into play, and with the prolonged pipeline life of the pipeline of this liner hose reparation 30～50 years.The technological scheme that realizes this liner hose is:
The non-trenchless rehabilitation liner hose of inversion method under ground piping, be characterized in: by outer composite soft tube, internal layer is that a diameter is formed greater than outer composite soft tube and with the knitting felt flexible pipe of the disjunct polyester of outer composite soft tube two big departments, main body is outer composite soft tube, and internal layer is that polyurethane film, glass fiber mesh, the knitting felt of reinforcement polyester are three layers of junctional complex.Glass fiber mesh (rise humidification) by mechanical acupuncture in strengthening the knitting felt of polyester surface, polyurethane film (TPU) is directly the granule of TPU to be extruded through extruder, be compound in the glass fibre wire side of strengthening the knitting felt of polyester behind the casting film-forming, such effect is that bonding intensity is stronger, in the middle of do not contain any binder, once-through, finally can reach, and finish the optimum efficiency of engineer operation, given full play to polyurethane film (TPU) properties of materials, what make flexible pipe is directly to form by high temperature hot pressing with the seam press strip of TPU to edge fit, passes through last according to different operation pipelines at last, following seam press strip is made different caliber flexible pipes; The knitting felt flexible pipe of internal layer polyester, for the knitting felt of single-layer polyester forms flexible pipe by the butt joint of interface tooled joint, and diameter is greater than outer composite soft tube.The purpose that adds the knitting felt flexible pipe of internal layer polyester is for the new pipeline that forms after engineer operation can reach certain wall thickness requirement, and is beneficial to the abundant permeability of integral lining flexible pipe epoxy resin-impregnated before engineer operation.The knitting felt hose diameter of internal layer polyester is that integral hose is through after overturning in engineer operation greater than the purpose of outer composite soft tube diameter, and the knitting felt hose inner wall of internal layer polyester links to each other with old inner tube wall at skin.
The utlity model has following beneficial effect: thermoplastic property and the irreplaceable elasticity of other plastic film of utilizing polyurethane film (TPU), can make its (flexible pipe before uncured for flexible structure) in pipe-repairing be repaired inner-walls of duct and fully be connected, can repair angle of bend≤45 ℃ and difformity pipeline: circular, oval, square or special-shaped pipeline.Carry the different medium pipeline: oil, gas, water, industrial chemicals.And internal lining pipe has rotproofness, anti abrasive advantage, and the strength of materials is big, and the underground water problem of infiltrating is thoroughly solved, and the long-pending loss of conduit section is little, smooth surface, and the current friction descends, and has improved the negotiability of pipeline.Material is environment-friendly materials.
