DD141094A1 - CABLE CHANNEL TUBE FOR THE LAYING OF CABLES - Google Patents

Abstract

Cable duct pipe for laying power supply cables Information transmission and the like. The aim of the invention is the easy laying of cables in cable duct pipes, a good Tightness of the butt joints, high resistance to mechanical and static loading and reducing the effort in the Laying and maintaining the cable network. The object of the invention is to create a component whose tubing with good sliding properties and whose joints ensure a good tightness. The solution according to the invention is a cable channel tube, preferably a Bell sleeve pipe, rait pipe pulls and linings of good Sliding property of the inner surface and good tightness of the butt joints, preferably by means of rolling rubber. The lining of the pipes is from metallic or non-metallic pipes or surface coating educated.

Title of the invention

Cable duct pipe for laying cables.

Field of application of the invention

Cable duct pipe for laying cables such as for the power supply, the transmission of information and the like in the underground space.

Characteristics of the known technical solutions

The laying of several lines of different supply carrier in the underground space is usually done together in a route. Compliance with the system of routing and protection against mechanical and static stress occurs, for example, by cover stones or blocks, by individual or bundled thermowells, a disadvantage of using cover stones is that the lines are not protected against water and not interchangeable, without again Aufschachtungen must be done with the known disabilities and expenses. When using molded bricks, the expense of manual installation, the poor sliding properties of the pipelines and the poor watertightness of the connecting joints are disadvantageous. When using protective tubes made of plastic, the required carrying capacity is achieved by high consumption of raw materials; the watertightness of the pipe joints is produced with great time and additional material.

Object of the invention

The aim of the invention is the easy and fast laying of cables in project execution, network expansion and maintenance in protective cases with good tightness and high

30resistance to mechanical and static stress; the avoidance of subsequent repeated excavations; Reduction of the workload for laying, replacing and maintaining the pipeline network and the economic use of domestic raw materials

Explanation of the essence of the invention

The invention has for its object to provide a device with pipe runs, which has a high resistance to mechanical and static stress 40und the butt joint is formed so that a good tightness is ensured; in that the pipe elements arranged in the component are provided with a lining which has good sliding properties for easy warping of the cables and that the component can be laid in an assembly construction.

According to the invention, the object is achieved in that the allocation scheme of the pipelines is shown in a cladding tube by the corresponding number, size and arrangement of the tube trains in the cladding tube by means of a filler such as mortar by casting or pressing is displayed.

5OAIs cladding tube is preferably a sleeve tube such. used a concrete bell muff tube; it is also possible to use socketless pipes, possibly with a sleeve and the corresponding properties such as asbestos cement, glass, textiles or other materials.

The lining of the pipes may be stable or unstable; it can be per tube of a metallic or non-metallic tube with smooth inner surface or be smoothed by surface application. The more stable the lining, the less stable it is

Must be the filler; he may be configured to disc-shaped spacer display. The Kabelkanalrohrtrasse is formed by laying the Kabelkanalronre in the known manner such. for concrete bells or other types of pipes, only under

Filling the pipe laying scheme · When using concrete bell socket pipes, the joints are usually sealed using roll rubber in accordance with this laying technology.

embodiment

The invention will be explained below using an embodiment using concrete bell socket pipes.

In the accompanying drawing show:

Pig. 1: the cross section of the cable duct with a selected allocation scheme;

Fig. 2: the half-section of a concrete bell muff pipe in the course of a route;

Pig. 3: the half section of a smooth tube with sleeve over a route *

In a concrete bell sleeve pipe as the cladding tube 1, according to Pig × 1, a number of continuous pipe trains 2 are axially arranged in accordance with an allocation scheme, and are formed of thin-walled pipes as a lining 3. The space between the cladding tube 1, at the same time as äus-

The remaining formwork and the linings 3, at the same time as inner remaining formwork, are filled with filling material 4 such as e.g. completely filled in cement mortar. The inner formwork can also be formed by a reusable device and the liner 3 becomes

90 formed by surface application or coating of the filler.
