This creates significant problems when such pipes are laid under water, because they do not sink but, because of their buoyancy, flow. In order to lay such pipes to their designed position under water they are to be provided with additional weights. This creates additional costs and takes additional time to be laid. Production of pipes of the same crown load capacity requires more material.
  • a pipe of larger nominal diameter has a multilayered wall, wherefore the wall is thick and the pipe has a large total weight. All this has negative impact to the costs of building of underwater pipe systems by such pipes.

All this does not suffice for the thermoplastic pipes to sink in water without adding extra weights.
  • the hollow corrugated reinforcing pipes may be of different shapes: circular, oval, square, rectangular or trapeze.
  • the pipes for reinforcement may be fitted to the thermoplastic pipe outer shell as several rings or as a single spiral.
  • thermoplastic pipes When such thermoplastic pipes are being laid in water, such as submarine discharges, their relative small weight requires production of weights usually made of concrete, that are fitted on the pipes to prevent their buoyancy, which increases the costs of such works.
  • the essence of the invention is thermoplastic pipe with reinforced spiral and the production procedure thereof.
  • thermoplastic pipe with reinforced spiral it is used a thermoplastic pipe with a hollow corrugated spiral.
  • a hollow corrugated spiral that is wound around the thermoplastic pipe is reinforced by being filled with a liquid mixture that solidifies shortly after being injected into the hollow corrugated spiral.
  • To reinforce the spiral used are cement, concrete or gypsum mixed with water. The mixture is pumped into the hollow corrugated spiral. The mixture fills completely the corrugated spiral interior and does not allow circular movements once it solidifies or separation when the solid matter cracks. When the liquid mixture appears at the opposite end of the reinforced spiral, pumping is stopped, and both spiral ends are plugged.

  • thermoplastic pipe with the reinforced spiral B is produced by filling the hollow corrugated spiral 2, that is wound around the thermoplastic pipe with the hollow corrugated spiral A, with the liquid mixture 4.
  • Production of thermoplastic pipe with reinforced spiral comprises the following operations: preparation of the reinforcing mixture 4, injecting the mixture 4 into the hollow corrugated spiral 2 with the pump P that is connected to the intake end of the hollow corrugated spiral, and closing the reinforced spiral intake and outlet ends with the plugs 5 once the hollow corrugated spiral 2 is filled with the mixture 4.

  • the prepared mixture 4 is to be liquid to be more easily pumped with the pump P into the hollow corrugated spiral 2, Figure 4.
  • Parts of material and water in the reinforcement mixture are determined empirically, to enable the mixture 4, before solidifying, to completely fill the circular corrugations 3 in the hollow corrugated spiral 2. This prevents circular movements of the solid matter once it solidifies and separation of the solid matter when it cracks.

  • thermoplastic pipes with several ring reinforcements may be applied also to thermoplastic pipes with several ring reinforcements.
  • the reinforcement procedure is more expensive, since intake and outlet openings are to be made in each and every ring separately.
  • thermoplastic pipe with reinforced spiral B has significant advantages relative to the thermoplastic pipe with hollow corrugated spiral A.
  • thermoplastic pipe with the reinforced spiral B significantly increases the pipe crown load capacity and decreases its deflection, which is very important in lying of duct piping systems.
  • the thermoplastic pipe durability is increased, and the mixture used for reinforcing the corrugated spiral increases the specific gravity and enables better sinking of the thermoplastic pipe in water.
  • Reinforcing the spiral enables significant decrease of quantity of the thermoplastic material used in the total weight of the thermoplastic pipe with reinforced spiral.
  • Reinforcing the hollow spiral with low costing materials and decreasing quantity of the thermoplastic material used significantly contribute to decreasing participation of costs of the thermoplastic material in the total cost of the thermoplastic pipe with the reinforced spiral B.
  • thermoplastic pipe with the reinforced spiral B has a very wide application. Due to its fine mechanical, hydraulic, chemical and thermal properties and its durability, it is applied in drainage, sewage and water transportation in:

Abstract

Le problème décrit par la présente invention est que les tuyaux thermoplastiques existants dotés d'une spirale ondulée creuse (A), lorsqu'ils sont placés dans l'eau, exigent une charge supplémentaire à l'aide de poids afin qu'ils puissent couler. La solution selon la présente invention consiste à produire le tuyau thermoplastique doté d'une spirale renforcée (B). La spirale ondulée creuse (2) est remplie de mélange (4) qui se solidifie après avoir été injecté dans la spirale. La spirale est renforcée au moyen du mélange d'eau et d'un des matériaux suivants : ciment, béton, gypse, ou un autre matériau, pompé à l'aide d'une pompe (P) dans la spirale. Une fois solidifié dans la spirale, le mélange ne peut pas se déplacer circulairement ni se diviser après fissuration. Une fois que le mélange sort à l'extrémité opposée de la spirale, l'injection s'arrête et les extrémités d'admission et de sortie de la spirale sont fermés à l'aide de bouchons (5). La spirale ondulée peut être remplie du mélange également par un certain nombre d'ouvertures (6) auxiliaires, et peut avoir diverses formes externes. Le tuyau thermoplastique doté de spirale renforcée (B) présente des avantages significatifs par rapport au tuyau thermoplastique doté de spirale ondulée creuse (A) : capacité accrue de charge de couronne, flexion réduite, durabilité accrue, gravitation spécifique accrue, meilleur ancrage dans l'eau, réduction de la partie en matériau thermoplastique par rapport au poids total ; il coule facilement dans l'eau sans l'ajout de poids ; réduit les coûts et le temps nécessaire à la construction de systèmes sous-marins.
