Definitions

  • corrugated synthetic resin pipe specifically, a corrugated synthetic resin pipe is shown in which the main body has a cylindrical shape and a reinforcing convex portion is spirally wound around the outer wall of the main body.
  • connection flange is not securely welded to the synthetic resin pipe, it will cause water leakage, and if the connection flange surface is deformed, it will also cause water leakage. Carefully install the connection flange. There must be.
  • the foamed molded body is preferably molded on both ends of the tube wall.
  • the foamed molded body may be formed on a part of the outer surface and the inner surface of the tube wall, and a foam sheet may be wound on the other part of the inner surface.
  • the resins are highly compatible with each other, and heat fusion (hot) can be performed without using an adhesive or the like.
  • the tube can be easily fixed to the tube wall by the melt.
  • the tube has an adhesive strength that can withstand the foaming pressure when the foamed molded body is injected, and does not peel from the tube wall. Even if a hot-melt adhesive is used, the same effect is produced.
  • the tube walls 2 of the synthetic resin tubes 1A and 1B with spiral waves are formed in a spiral wave shape, and at one end portion 10 (the left end portion in the drawing) of each tube as shown in FIG.
  • the cylindrical insertion port 3 is formed by applying a synthetic resin layer as a foamed molded body that fills at least the recess (valley) 2a forming the wave shape on the outer surface side of the one end 10.
  • the end portion 11 (the right end portion in the figure) has a receiving portion 4 made of a synthetic resin that is attached to the outer surface of the other end portion 11 and extends in a cylindrical shape outward in the axial direction (right direction in the figure). Is formed.
  • a substantially triangular shape made of a resin molded body (for example, a coated steel plate) in which a steel material (steel plate having a convex cross section) 22 is provided on the outer peripheral side of a main body portion 20 as a synthetic resin tube wall having a substantially flat inner surface.
  • the reinforcing convex part 21 having a shape or a substantially arc shape is provided in a spiral shape, and the reinforcing convex part 21 forming a mountain part with the main body part 20 is formed by melting and extruding a partially molded body of the main body part 20 on a rotating shaft.
  • the reinforcing projections 21 can be similarly spirally fed and integrated on the partial molded body, and can be efficiently produced.
  • one or a plurality of tube bodies 110 are provided in a part of the region covered with the foamed molded body.
  • one or a plurality of pipes 110 are provided in the recess 2a covered with the synthetic resin layer 8 among the recesses 2a of the main body part 20 of the synthetic resin tube 1B with spiral wave, and the main body part 20 of the receiving part 4 is provided.
  • One or a plurality of tube bodies 110 are provided in the recess 2 a covered with the synthetic resin layer 8 in the recess 2 a, and 1 in the recess 2 a covered with the synthetic resin layer 5 among the recesses 2 a of the main body 20 of the insertion port 3.
  • a plurality of tube bodies 110 are provided.
  • the pipe body 110 is arranged so as to surround the region in the circumferential direction of the concave portion 2 a of the main body portion 20.
  • symbol is attached
  • the resin pipe as the pipe body 110 is disposed in the recess 2a.
  • the resin pipe, the resin tube, and the resin hose may be disposed in combination.
  • a resin pipe and a resin tube can be disposed in one recess 2a, and each of a resin pipe, a resin tube, and a resin hose can be disposed in one recess 2a.
  • the synthetic resin pipe can be reduced in weight and cost.
  • an FRP layer 8a can be provided on the outer peripheral surface.
  • an engagement protrusion 70 is provided on the inner peripheral surface of the straight tube portion to engage with the peak portion of the tube wall 2. It is possible to increase the strength.
  • the receiving portion 4 is formed by coaxially connecting the pipe material 7 having a diameter larger than that of the synthetic resin tube with spiral wave 1C on the outer surface side of the other end portion 102a.
  • the synthetic resin material of the synthetic resin layer 8 is filled in at least a gap between the pipe material 7 and the synthetic resin pipe with spiral wave 1C.
  • an O-ring 6 is interposed between the insertion port 3 and the receiving port 4 as a seal member.
  • an annular groove 50 into which the O-ring 6 is fitted is formed on the outer surface of the insertion port portion 3, and the tubes are connected with the O-ring 6 fitted into the annular groove 50.
  • the annular groove 50 in which the O-ring 6 is mounted is notched at the distal end edge of the insertion slot 3, but is formed at the base edge or the middle part on the opposite side of the insertion slot 3. May be. Moreover, you may provide in the receptacle part 4 side.
  • step S4 a synthetic resin material for forming the synthetic resin layer 8 is injected into the sealed space.
  • the injection is performed through the injection port 62 communicating with the sealing chuck 60 in the axial direction.
  • the injection method is not limited at all, and the sealing chuck 61 or the gold for forming the receiving surface 40 is formed.
  • An inlet may be provided in the mold.
  • FIG. 19 (b) is an enlarged view of the scratch F. Although the line 8b forming the edge of the outer peripheral surface of the receiving port was lost over the range 8c, there was no problem in strength.
  • the present invention can be used as a synthetic resin pipe applied to a drain pipe under a road, a large drain pipe for sewer, or the like.
