Description

BACKGROUND OF THE INVENTION The present invention relates to a piping system for conveying fluids, in particular liquids, in particular pressurized drinking water, industrial water and gravity wastewater.

It is known that pipe rigid systems, pipeline systems for the transport of flowing fluids, permanent sections and portions of rigid pipes and fittings, especially at compasses and junctions, can be formed by forming nodes and / or shafts. Nodes and shafts significantly increase the time and cost of building a pipeline network. This is particularly true where the pipe system also requires the cutting of tubular fibers.

The nodes are, due to the shaped parts used, the more rigid parts of the network and are therefore more susceptible to failure. This sensitivity is further increased by the number of pipe joints that are specifically densified at such sites.

It is an object of the present invention to provide a pressurized or gravity piping system for conveying fluids, especially water or wastewater, which can be accomplished in a shorter period of time, using simpler construction technology and less costly than existing facilities of the same type.

The invention is based on the recognition that nodes

- consequently, reducing the number of fittings and pipe joints can significantly reduce the number of rigid locations and sections, thereby reducing the number of failures and opportunities. We have also discovered that the number of nodes can be reduced by forming the bends of the pipe not by rigid sections, but by flexible pipe sections, thus saving a considerable part of the assembly work. not at labor prices, but at tea repazin. Finally, it has been discovered that the application of a resiliently deformable flexible tubular material to the network increases the flexibility of the entire system by making the horizontal and vertical bends of the conduits hydraulically more advantageous than the use of conventional rigid sections with radiuses appropriate to the operating needs.

Based on these findings, the object of the present invention has been solved by a duct system having a main duct and a branched duct having ducting and connection points, the duct system being characterized in that at least the ducting is at least in the vicinity of the ducting and docking points. they are made of a flexible, resiliently deformable plastic pipe that is resistant to earth pressure from the outside. Externally applied ground pressure is, of course, understood to be the pressure normally applied to underground pipelines.

A preferred embodiment of the piping system is characterized in that, in the case of gravity lines, the connecting lines are connected to the main line by means of an arrowhead or / and a half-hole or / and χ-shaped connector.

The piping system of Fig. 1, which in this case is a sewerage system of a sewerage network, but is also geographically identical to a pipeline system of a municipal sewerage network, has a utility mains 1 which may be made of either a rigid or a flexible pipe. 5 • · ·· • combination of pipes. Cleaning or / and separating shafts 7 are installed on the main line 1, distributed at intervals appropriate to the maintenance needs. If no manholes 6 are installed at the bends of the main line 1, the bends are formed by flexible / bent / 8-arc sections.

Depending on the spatial or elevation line of the home connection 5, the connections to the main line 1 are shown by the arrow-shaped connector 4 shown in Figure 2 or the half-arrow connector 3 shown in Figure 3 or the V-shaped connector 2 shown in Figure 4. using a connector. The couplings 2-4 are preferably made of plastic. In the case of a water supply system, a wide Gibault gland or other drill bit may be used to connect the main line and the connection lines. In the case of double vertical joints, the ϊ-shaped coupling 2/4 is best. Fig. 6 / installation (see also Fig. 6), but if a double horizontal connection is required, the arrow-shaped coupling 4/2. / is applied. The semi-linear coupling 3 of Fig. 3 can be installed at either vertical or horizontal connections.

The connecting pipes 5 may be made of elastically deformable pipes, for example laryngeal tubes, which, however, must also be capable of exerting external pressure, ie they must not be subjected to external forces. The connecting cables 5 between the main line 1 and the house connection shafts 6 belonging to the housings 12 are straight, smooth depending on the horizontal and height position of the connection points.

- 6 or spatial curve - made up of curved elastic wonders that can be cut to size on site. Joints can be made by gluing, welding or clamping or by a combination of these methods.

- for example, in the case of a plumbing network, they allow the meter to be placed or disconnected for some purpose and to separate utility and home facilities ·

Between the house connection shafts 6 and the external connection points of the houses / buildings 12, flexible connection cables 5a adapted to the local conditions and satisfying the operational needs are also installed.

In Fig. 1, as indicated above, at the junctions of the main line 1 and the connection lines 5, the lines 2-4 are shown. 2-4. In Figures 5 and 6, schematic drawings of larger scale illustrate the elevation connection system of the main pipeline 1 of the public utility pipeline network and the domestic manholes 6. 5 and 6, the previously used reference numerals are used mutatis mutandis.

If the height guiding of the main line 1 allows a connection without a vertical break, the flexible connection line 5 starting from the connection shafts 6 - as shown in Fig. 5 with an arrow-shaped connector 4/2. / or or ..

If there is a large difference in height between the main line 1 and the domestic manhole 6, a vertical bending of the flexible manifolds 5 can be used, as shown in Figure 6, to create a connection between the main manifold 1 and the manifolds 5. Think / 4. / but may be used for single-sided connection, with half-arrow-shaped connector 3/3. Figure / also.

As with the sewer connections shown in Figures 5 and 6, the vertical connections of the drinking and industrial networks can be solved; however, there is no fixed positioning of the public utility main line.

The domestic manhole 6 shown in Figures 7 and 8 is unified in the sense that it can be used in virtually any public sewerage network, such as a gravity sewer or a pressurized plumbing network. The manhole 6 has a prefabricated reinforced concrete base 9, also a prefabricated reinforced concrete lightweight cover 10, and a prefabricated / iron / concrete vertical closed-end, preferably annular, cylindrical, single-member wall 11. The manhole elements are made of waterproof and antifreeze quality concrete. The semicircular passage 13 of the channel is recessed into the bottom element 9 and the connecting pipe ends of the channel sections are glued there. For this purpose, a manifold 14 extends from the manhole 6 as shown in Figure 8.

* Is shown, where the end piece of the flexible connection pipe 5 glued to this pipe connector is also indicated. For example, the annular member 11 has a height of 100-125 cm, a diameter of up to 70-100 cm and is provided with breakthroughs in preferred locations. The bottom member 9 and the wall member 10 are preferably bonded to one another. For example, if the manhole 6 is part of a plumbing network, the manhole 6 is used to secure the main stopcock and the water meter with a pair of clamps (not shown) concreted in the bottom member 9 of the bottom member. Thus, the connection shaft 6 here functions as a water meter mine, and only one node is established at the water meter shaft.

Advantageous effects of the invention may be summarized as follows:

It is an essential advantage that the number of shafts, junctions and fittings in the pipeline system of the present invention can be significantly reduced since the bends and intersections, as well as the house connections, are solved or bridged by elastic pipes in a flat or spatial manner. As a result, costs during the investment phase are significantly reduced and time and labor can be saved. During the operational phase, there is an advantage in increased operational safety and easier maintenance work. The advantage of the invention is particularly evident in the crossing of other utilities and in the construction of house connections. · If the entire pipeline network is flexible and made of pressure-resistant tubular material, it is possible to install the pipeline at field level, for example. • · · · · · · · · · · · · · · · · · · · · · · · · · · · ·

Because the piping system made of partially or fully flexible tubular material has slight transitions compared to conventional, clogging! the smaller operation and maintenance of the hazard, as mentioned, is simpler than that of a network constructed entirely of rigid pipes and fittings. The use of unified home shafts can economically increase the entire system.

The invention is, of course, not limited to the embodiments detailed above, but may be practiced in many ways within the scope of the claims.
