All known technical solutions have one thing in common, that in the case of a defect, a necessary heparization, a general renewal according to the useful life of the media-carrying Sohres, on the media-carrying Bohr existing Wärmedämmstoffschichten' must be removed and are usually destroyed and reused only in rare cases can be. In addition there is the disadvantage ₃ · that penetrating moisture between the media-carrying Sohr and the insulation material or the skin and the outer skin leads to the moisture penetration of the insulation, so that a Beduzierung the thermal insulation properties of the damastoffes occurs and thus greater energy transfer losses occur "This usually results in strong external corrosion media-carrying steel pipe, with a significant reduction in the useful life.

According to WP 139 635 the leak must be located in the event of an accident and then a part of the route must be dug up, which leads to considerable damage and too high construction costs, especially in urban areas under paved traffic areas. In addition, ₅ that in the case of replacement of the media-carrying ears with insulation and outer shell considerable costs for disassembly and selective separation of the different materials and their repatriation as secondary raw materials arise.

Another disadvantage is the mechanical stresses on the organic foam which occur with changing thermal stress on the media-carrying tube, which contribute to the destruction of the foam and thus to a change in the position of the media-carrying ear over a longer side space, so that the operational safety is endangered.

In the known technical solutions of thermal insulation, which are applied to pipelines 2.1t direct Erdverlegun ^ or in non-accessible channels, there are seasonal and weather-related impairments in the construction, which led su increased ^ -uvvand.

The enclosed pre-insulated heat dams Ie do not allow the production of the district heating system in one construction phase as a combined construction and equipment assembly. This results in the cost of equipment that can be avoided when installing half shells and using a one-step multi-phase assembly.

The aim of the invention is to reduce the outlay for the supply of buildings, building and technological installations with district heating, to achieve district heat transfer with lower energy losses, to increase the utility value properties and to extend the service life thereby.

In particular, by preventing moisture penetration outer corrosion damage to media-leading Hohrleitungen avoided and by appropriate storage of the media-carrying Hohre the thermal and mechanical stresses of the insulating material can be reduced.

Explanation of the essence of the invention

The Erfindimg is based on the object, halved insulation elements for sedienführeηde piping in such a way that a linrohr- or Zweirohrleitungsmontage combined. Construction and equipment assembly can be done in one stage and a subsequent insertion or retraction or later replacement of the media-carrying district heating pipes is job-free possible.

According to the invention, this object is achieved in that halved MehrschichtdämmeIIe se nte by half inner .Stützrohre preferably made of asbestos cement or corrosion-resistant in Stahlblech old support elements are designed so that dainit the combined construction and equipment si ni n age in a • stage can be done and a subsequent Insertion or retraction or later replacement of the media-leading heating oil district heat pipes without destroying the heat-insulating mantle and the building envelope is possible.

The damping effect of the halved Hehrschichtdämnelemente that are used to support the media-carrying pipes, is achieved, in addition to the halved inner support tubes organic and / or inorganic insulating materials in the form of foams or mineral fiber mats or in combination of both insulating materials are used.

which are not grooved for bearing the 12sdienführenden tubes can be achieved without halved inner support tubes by organic and or inorganic insulation materials in Forra of foams or mineral Fasermattea or in Socibination both dams.

In the case of the combination of both insulating materials, the mineral fiber mat is glued to the half support tube or the two half support tubes and the outer surface of the mineral fiber mat is covered with organic polyisocianurate foam, which at the same time provides a complete etch seal and the outer Sonturstabilität takes over.

Corresponding to the length of the halved MehrschichtdämmeImtenIement8es, the load case as well as the formation as halved Einrohr- or Z ^ pipe elements are appropriate Abstütaelemente preferably connect with temperature-stable sieves with the halved inner support tubes, wherein the natural Sleblrraft of the foam can be shared in its phase of action.

The halved support tubes receive in the Hegel at one end a bump formation or Aufklechung, while the other end to the length of the insertion path over the

hersusrast; Thus, a simplified -montage the hal-finished elements in the Stcßbereich possible and in total can thus be made a closed stable thermally insulated structural shell with inlaid media leading Hohr in one stage.

In order to prevent the ingress of moisture, the insulating material on the entire surface and

rich, the cut and joints as well as the Burchdringungsstellen the supports rejected the halved Hehrschicht insulation elements usually by, various materials, such. Tereposide resin, silicone rubber, polyurethane jetting compound, and the like. liquid-tight to use seal and glue in the longitudinal and butt joints.

By the partial Heflektion of the radiating heat of the

Support pipes is the halved anti-theft target because of its higher utility values both for the untachable laying in structural sheaths as well as for unaided district heating pipes.

When using the combined construction and equipment assembly in a construction stage, the production in several phases can be done in succession, wherein in the first phase, the assembly of the elements with the lower halved Mehrschich.t dämm lementsen is made, in the second phase ' ^: Fernwärmeleitung above The channel troughs are welded together as a drill string between adjacent structures and tested, so that in the third phase it is possible to drill the drill string and close the structural envelope.
