Abstract

"compensated piping" for underwater use for the transport of liquids or gases, especially for the conduction of water in marine transfers, characterized essentially by having a round, square, rectangular, oval, or any other section, made by extrusion in plastic material, its interior being subdivided so as to have a main chamber (1) through which the liquid or gas circulates, and one or more smaller chambers (2), arranged symmetrically according to a plane of vertical symmetry of the assembly in which they are placed.

Description

Compensated pipe

Technical field

The present invention relates to a pipe or submarine conduit for the transport of liquids or gases, especially for the conduction of water in marine transfers.

Background of the invention

This type of pipe is designed to drive liquids or gases by the seabed, river or of a reservoir or swamp, there are basically two types, which are they are suspended under floats and held in place by means of guide cables that are fixed to the seabed, and those that are settle directly on the seabed. To this type of pipes in The present invention refers specifically.

Liquid and gas conduction pipes intended to settle directly at the bottom of a medium aquatic are constituted by metallic tubular sections, built on land, which are assembled in movable platforms from which the channeling, although there are cases in which the pipe is assembled on land and systematically displaced inland.

In any case, these pipes are provided of ballasting means intended to balance its weight in water to ensure proper settlement at the bottom.

The ballasting is done mainly by Concrete blocks fixed around the tube. This system of fixation presents, first of all, a block of concrete can easily damage the surface of the pipe, and in second, it has been shown that the subjection of such Concrete blocks are not entirely effective in the long term, since The movements of the pipe makes concrete surfaces in contact end up deteriorating, loosening these fixations and worsening the settlement.

As a solution to these problems they have developed various pipe models; Examples of this type of pipes are those described in patents No. P448425 and P472693.

The first describes a pipe to which Associate by means of flanges one or more minor pipes in which Enter some kind of ballast. The second describes a pipe outside of which devices are mounted ballast surrounding the pipe, fixed by means of rings anchorage.

These devices solve the problems initially described, however they are complicated to assemble and to lay on the seabed, being metallic and built on the mainland as sections to be mounted on Water.

Description of the invention

Generally speaking, the present invention will be refers to a compensated pipe specially designed for use underwater whose section can be round, square, rectangular, oval, or in any other way, being made by extrusion in plastic material.

The inside of this pipe is compartmentalized so that it presents a main camera by the that circulates the liquid or gas, and one or more smaller chambers, symmetrically arranged according to a plane of vertical symmetry of the set. Inside the smaller chambers, a ballasting product, preferably concrete.

The external surface of the pipe is preferably rough so that it is easily covered by the underwater fauna of the place once it is settled in the background marine or river.

This structure allows the in-situ pipeline to be manufactured during laying, by means of a mobile floating platform, in which an extruder station, a concrete production station, a cooling station and an energy station for supplying the rest of the electric power are arranged. of facilities.

The extruder station will preferably be made up of several plastic extruders that feed an extrusion head with the shape of the pipe. That station make a continuous line of pipe that can be directly submerged or, sectioned in sections for use later. The concrete produced is injected directly during extrusion in the smaller chambers, after which the station chiller solidifies the assembly which is thus ready for use.

The new pipe greatly improves the performance of the devices described in the state of the technique, since the ballast measures are incorporated in the own pipe from the moment of its extrusion, so it is its mismatch impossible, and on the other hand, said pipeline can be manufactured in the same place where it has to be submerged, which means extraordinary economic savings by being eliminated within the global of costs related to transport, storage and distribution of the tubes

Description of the drawings

In order to illustrate how much so far we have exposed, is accompanied by the present specification of a sheet of drawings in which an example of only illustrative and non-limiting realization of practical possibilities of realization.

In said drawings, Figure 1 represents a perspective view of a pipe according to the invention seated in a seabed, while figures 2 to 6 represent different designs of possible sections according to the invention.

Example Description

The present invention relates to a pipe Compensated specially designed for underwater use by extrusion in plastic material, whose section is compartmentalized so that it presents a main chamber (1) by the one that circulates the liquid or gas, and one to four smaller chambers (2), according to example, in which concrete (3) is introduced into the moment of extrusion.

The external surface of the pipe is rough (4) so that it is easily covered by the underwater fauna of the place (5) once it is seated on the seabed or riverbed (6).

Claims (2)
