Definitions
- the invention relates to production of thermoplastic pipe with reinforced spiral.
- International Patent Classification it is classified as the Field F - Mechanical Engineering, Class F16 - Production procedure, Subclass F16L, that includes Pipes, Group F16L 11/11 - Pipes with corrugated wall.
- Thermoplastic pipe with hollow spiral is produced from PE, PP and PVC materials,
- the specific gravity of such materials is lesser than that of water. 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.
- thermoplastic pipes the construction of which will enable their underwater laying without additional weights, hard enough, and enabling less costing underwater pipe systems.
- thermoplastic pipes of a larger diameter
- a plastic pipe of a lesser diameter is wound around its outer shell, as reinforcement.
- the lesser diameter pipe's inner side is corrugated, and it is wound around the larger diameter pipe like a spiral. This increases the thermoplastic pipe crown load capacity, decreases its deflection, and increases the pipe material durability. 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.
- the corrugated spiral may be of circular, oval, square, rectangular or trapeze shape.
- thermoplastic pipes of corrugated form and thermoplastic pipes with multiple ring reinforcements may also be applied to thermoplastic pipes of corrugated form and thermoplastic pipes with multiple ring reinforcements.
- Thermoplastic pipe with reinforced spiral when laid in water, sinks easily, requiring no additional weights, which significantly cuts the system building costs and time.
- Figure 1 shows thermoplastic pipe with hollow corrugated spiral and a cross- section detail through the corrugated spiral - front view.
- Figure 2 shows the thermoplastic pipe shown in Figure 1 - top view.
- Figure 3 shows the thermoplastic pipe shown in Figure 1 , cross-section X-X - top view.
- Figure 4 shows the thermoplastic pipe after filling the corrugated spiral with the reinforcement mixture - front view.
- Figure 5 shows the thermoplastic pipe after filling the corrugated spiral with the reinforcement mixture and a detail of the reinforced corrugated spiral cross- section - front view.
- Figure 6 shows the thermoplastic pipe shown in Figure 5, cross-section Y-Y - top view.
- Figure 7 shows the thermoplastic pipe shown in Figure 5, cross-section Z-Z - front view.
- Figure 8 shows thermoplastic pipe with reinforced spiral - cross-section of the reinforced spiral ends plugged.
- Figure 9 shows thermoplastic pipe with reinforced spiral with two auxiliary plugged openings after the reinforcement mixture is injected into the spiral - front view.
- thermoplastic pipe is a pipe of a larger diameter, around its outer shell being wound a hollow corrugated plastic pipe of a lesser diameter, like a spiral.
- the lesser diameter corrugated spiral serves as reinforcement of the larger diameter thermoplastic pipe.
- the hollow spiral increases the thermoplastic pipe crown load capacity, decreases its deflection, and increases the pipe material durability. All this does not suffice the thermoplastic pipes to sink in water without adding extra weights.
- the hollow corrugated pipes for reinforcement of the thermoplastic pipe may be of different outer shapes: circular, oval, square, rectangular or trapeze.
- To the thermoplastic pipe outer shell may be fitted several rings.
- thermoplastic pipe with hollow corrugated spiral of circular shape.
- thermoplastic pipe with the reinforced spiral B it is used the thermoplastic pipe with the hollow corrugated spiral A.
- Figures 1 and 2 show the thermoplastic pipe with the hollow corrugated spiral A, front and top view.
- the hollow corrugated spiral 2 Around the outer shell 1 of the thermoplastic pipe is wound the hollow corrugated spiral 2, its inner shell having circular corrugations 3.
- Figure 3 shows cross-section X-X of the thermoplastic pipe with the hollow corrugated spiral.
- 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 outlet end of the hollow corrugated spiral 2 is left open, so that the mixture can force all the air from the spiral out.
- mixtures of different materials that solidify after a shorter period of time.
- 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.
- Figure 5 shows the thermoplastic pipe with the reinforced spiral B, front view and partial cross-section of the reinforced spiral 2.
- Figure 6 shows cross-section Y-Y from Figure 5, through the thermoplastic pipe with reinforced spiral B.
- thermoplastic pipe and the hollow corrugated spiral are of greater lengths, along the corrugated spiral 2 may be made several auxiliary openings 6 for injecting the reinforcing mixture 4 by segments, Figure 9. This guarantees better filling of the circular furrows 3 inside the spiral. Once the mixture is injected, all auxiliary openings are to be closed.
- 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.
