Description

The present invention relates to a method and apparatus for the construction of pipelines, in particular gravity channels 20 to 60 cm in diameter. The present invention provides for the installation of a pipeline to be placed below the groundwater table without dewatering. The application of the invention is not a requirement for dredging priority work, but it can also be used for tumbled work. The material of the pipeline laid with its application is not required, and the method and apparatus of the invention can be used for laying a pipe of any material or diameter. Shafts, junctions, joints may also be present in the pipeline section so that the pipeline is used in the most general sense for the purposes of the present invention.

Each of the known pipe-laying procedures is used to keep groundwater away from construction work by a special measure. Groundwater retention is done by lowering the groundwater or by excluding the water. Groundwater is lowered from the work area by means of a sinkhole system (vacuum, or filter or deep gravity). Waterproofing prevents water from entering the trenches through waterproofing, waterproofing or, less frequently, by freezing or chemical layers. The pipeline is then made from elements (concrete, asbestos cement, acrylic, steel, and manhole elements), monolithic concrete, or smaller structural elements (brick, concrete slabs), and then fill the trench and dismantle the dewatering plant.

The construction method described above does not necessarily have to be applied to all pipeline construction, but if the groundwater is at a height above the bottom of the trenches and cannot be removed by open water, the slow and costly procedure described above has been used so far.

Other solutions are known to prevent the pipeline from being submerged in groundwater. Under pressure or vacuum drainage systems that use external pressure to move sewage transported through the sewer can avoid the need for gravity drainage, so that manifolds can follow landforms and remain above groundwater. However, this system is very expensive because of the pressure or suction equipment and the complicated construction of sewage connections, which means that for a long time it will be necessary to establish gravity channels or other pipelines below groundwater level.

SUMMARY OF THE INVENTION The present invention relates to a process for the construction of a pipeline for surface and groundwater level, and to a method for carrying out the process, which enables the pipeline to be constructed without the need for groundwater leveling and dewatering.

The invention is based on the discovery that dewatering of trenches and their soil environment can be avoided by preparing pipe sections above the groundwater level by providing a flexible deformation and thus waterproofing connection of the next pipe section. and then, after immersion and waterproofing, only after the inside of the pipeline section has been dry, the associated pipeline sections are made permanently material-consistent with the material of the pipeline section to provide a watertight protection. It is a further realization of the invention that the above-described process may be carried out by means of temporary switching drive and control devices which are both recovered and lost.

Based on these findings, the object of the present invention has been solved by a process characterized in that the trench for pipe-laying is at least partially formed by underground earthwork and that pipeline sections are prepared for laying above the water level while and / or having auxiliary structure (s). connect and then submerge the pipeline sections one after the other, join them together, - position, secure and secure the joined connection, and then re-fill the ditch while, or after, the connected connection of the pipeline section ) at least the water is removed from the internal environment and the conduit sections are internally made continuous at this joint (s). According to a further feature of the invention, the trench is formed at least partially by a vertical boundary surface, folded planking, and only by a barrier above groundwater. Again, according to a further feature of the invention, the wiring section is assembled from a plurality of members and is prepared for laying. According to a further feature of the invention, at least one of the elements is installed in the conduit section as a shaft element or shaft access element and / or branching element and / or connecting element. According to other embodiments, the mounting platform is formed as a movable bench beneath the forks and / or above the groundwater level, in particular when the assembly bench is formed as a floatation device floating on the groundwater and floated out of the pipeline section prior to the water inlet. According to yet other aspects of the invention, during and after the preparation of the line section, auxiliary device (s) having at least one) are elastic, and the elastic auxiliary device is connected to itself as a reciprocating and / or annular member, at least one of the auxiliary devices is connected to the conductor section as a split mantle having a diameter greater than the shaft, and by joining, the resilient auxiliary device is positioned between the auxiliary device and the conductor region. It is also an embodiment of the invention to connect at least one of the auxiliary devices to the pipe section as a pipe element having a larger diameter than the pipe section. According to a further feature of the invention, the conduit section is submerged and / or joined and / or connected and / or secured and / or secured in at least a portion of the auxiliary structures, as well as waterproofing of the joint is formed by deformation of the auxiliary device (s) having the property of joining or by a separate operation. Again, according to a further feature of the invention, a portion of the auxiliary devices are disconnected and removed after the wire section has been lowered and the workpieces have been completely filled, and / or the auxiliary device has been disposed after the fitting and / or the auxiliary device is inserted after the wire section is embedded with the partial filling of the working grooves from the wire section. According to a further embodiment of the invention, the work trench is at least partially filled with material which is self-solidifying and / or having an internal shear strength. According to a further aspect of the invention, the line section is subjected to a water tightness test prior to release and / or after the sealing of the joined connection is made, and in accordance with another embodiment, the material is continuously welded and / or soldered and / or glued.

The device according to the invention is characterized in that it has a temporary auxiliary device (s) for impermeability to waterproofing and a reciprocal auxiliary device (s) for moving, conducting and securing the pipeline section. A preferred embodiment of the apparatus is that the losing auxiliary device comprises an elastic rubber ring and a ruptured sheath and / or tubular member, but it is also possible to have the lanyard, tube laying carriage (s) of the auxiliary device for moving the wire section. According to another feature of the invention, the device has guide means (s) and securing means (s) coupled to the tube laying trolley. It may also be desirable if at least one of the recovered auxiliaries of the apparatus is a float; and a bench mounted on the float.

The site diagram in Figure 1 illustrates the need for area preparation. In the public area 2 bounded by the land boundaries 1, the utilities 3 are located. The construction task is to construct the 5 channels together with the connecting 6 channel sections. In order for the working channels 7 shown in Fig. 2 to be able to be removed by the underwater excavation according to the invention, preferably by means of mechanical equipment, the public utility pipeline sections 4 need to be replaced, thus providing free working space to reach the channel sections.

Figure 2 shows a first step of an exemplary implementation of the method of the invention in subsoil 10 delimited by terrain level 8 with groundwater level 11, forming a trench 7 with earthmoving machinery 9, partly underwater.

In Fig. 3, as a next step in the exemplary technology of the present invention, the tuft 12 is formed, optionally with a folded planking, supported by straps 14 held by the posts 13 above the groundwater level. The lower section 15 of the sheet is caught in the subsoil 10 below the raised trench 16. Next, the bandage structure 17 shown in Fig. 4 is provided, preferably made of soles 18 and rails 19.

5 and 6, which is able to roll over wheels 22 on axle 21 coupled to shaft 21 at working level 9. The carriage 20, as shown, is preferably biaxial and has a frame structure 24. Two (or more depending on the nature of the task) trolleys are connected to each other by the drawbars 23.

Then, the mounting level 25 shown in Figures 7 and 8 is provided, which in the exemplary case is a mounting bench 27 mounted on the float 26. Optionally, two or more floaters are provided with a continuous assembly 26 or a member assembly 27.

In Figures 9 and 10, on the assembly platform 27, which in this example rests on a float 26 floating on the groundwater level 11 in the trenches 7, the conduit section 30, optionally the pipe members 28 and the coupling members 29 are assembled. During preparation for laying, the wire section 30 rests on the mounting platform 27 via the supports 31. As shown in the figure, the conduit section 30 is connected by suspension 32 to the release member 33, which engages the actuator 34 with the frame 24 of the tube laying carriage 20. The suspension 32, the release member 33 and the actuator 34 together form the release member 35.

Figures 11 and 12 show further auxiliary structures for pipe laying. In addition to the feeder 35 connected to the frame 24, the fastener 36 and the guide 37 already connected to the wire section 30 are shown. The guide structure 37 also serves to bring the device into its design position. All. Fig. 2A shows the line 30 in two positions, A during preparation and B during lunge walking,

12, the wheel 22 and the axis 21 of the tube laying carriage 20 are not shown for clarity, but the line section 30 is only shown in the preparation position A, but the figure shows the displacement connection of the guide structure 37 to the line section 30.

Figure 13 shows the connection of two successively mounted wiring sections and part of the connection elements. The pipe section 28/1 and the shaft 38 form part of the preceding section 30/1. The downstream conduit section 30/2 comprises the tubular member 28/2 and the auxiliary device coupled thereto in preparation position A, the split jacket 39. The figure shows a dashed line of these elements, also in their intended position C after their release. In preparation position A, the conduit section 30/2, as described in connection with the preceding figures, rests on a float 26 floating on the groundwater level.

Fig. 14 shows elements in the vicinity of the conductor section 30 placed in the plan C position during the recharging of the trenches 7. 11 and 12 and the elements 32, 33, 34 thereof are not shown. The figure shows a guide 37 and a retaining device 36 attached to the frame 24 of the tube laying carriage 20. With the help of these, the embedding 40 is made of material of post-solidification or of internal shear strength around the conductor section 30 which is brought into the design position.

In Figures 15 to 16, the pipe member 28, the attached shaft 38, and other details are shown as parts of the conduit section 30. In the present case, the shaft 38 or the prefabricated pipe nozzle 41 formed as part of the shaft are fixed to the pipe element 28 by gluing. Fig. 17 shows a pipe end lubricated with an adhesive layer and a pipe nipple 41 before fitting. In Figures 15 and 16, auxiliary devices having elastic properties adhered to the bonded conductor section 30 are shown, in the example shown 43.

-4193216 shows rubber rings. Optionally, the rubber rings 43 are connected to the wall of the shaft 38 at the point where the downstream conduit section will fit.

In Fig. 17, the element shown in Figs. 15 and 16 is shown in a state of preparation. The pipe member 28 is not yet connected to the pipe 41 of the shaft 38, but already bears the adhesive layer 42 which will then attach it to the pipe 41 after assembly.

Figures 18 and 19 show a connection between a manhole 38 for a preceding conduit section and a pipe member 30 for the next conduit section and provide a materially continuous connection by gluing (Fig. 19) or additional flange 44 (Fig. 18) at the joint illustrates the auxiliary device used, showing the jacket 39 and the rubber ring 43. The sheath 39 and the tubular member 30 are joined by the adhesive layer 42. The pipe member 30 and the pipe fitting 44, the pipe fitting 44 and the shaft 38, and in Fig. 19, the pipe fitting 30 and the shaft 38 are also permanently connected by an adhesive layer 42. Between the jacket 39 and the shaft 38, the resiliently deformed auxiliary device shown in both figures, the rubber ring 43, provides a temporary watertight fit.

Figure 20 shows the final configuration of a shaft, which, in the case of the example, without the details shown in Figures 15 to 19, forms the bottom of a shaft that is materially permanently connected to the conduit sections 30 including the groove. The 46 expiring ladders are connected to it. The shaft is surrounded by a concrete collar 48 including a frame 47 with a connection above groundwater level 11. The frame 47 is designed to support an unguarded manhole cover.

In the schematic diagram shown in Fig. 21, the structural elements of the conduit 28, the tubular elements 28, the shaft 38 and the material continuity adhesive layer 42, and the auxiliary structures, the elastic rubber ring 43 and the split jacket 39 are shown. Recovered auxiliaries are not shown in the figure.

Figures 22 and 23 show another embodiment of the invention in two phases of assembly. Part 38 of the 30/1 wire section is the manhole 38. At the end of the wire section, a resilient auxiliary device 43 is provided. The conduit section 30/2 also has a resilient rubber ring 43 ', and the losing auxiliary device thereon is the tubular member 49.

In addition to depicting these in a new position, Figure 23 illustrates the post-assembly condition as well as the adhesive layer 42 which makes the wire sections materially continuous.

In the embodiments shown in the drawings, the wire and its connections are made of plastics (e.g., fiberglass-reinforced polyethylene) using a plastic adhesive, g steel and rubber, and the auxiliary structures recycled are preferably selected materials.

The invention will now be described with reference to the drawings.

For the construction of the planned pipeline, optionally 5 channels, the route is laid out and the crossover utility sections 4 shown in Figure 1 are replaced. Where appropriate a

The field level 8 shown in Fig. 2 is unfavorable for further work, so by preparing the work area, the working level 9 is produced and the work trench 7 is deepened from this level. If necessary, we establish or provide transport and access routes. In the exemplary case, the trenches are made with a vertical boundary as shown in Fig. 3, supported by tongue 12, optionally folded planking, supporting straps 14 and struts 13. The tamping 12 preferably extends below the working floor 16 by about 0.5 m to provide stability with a lower support. For safety and security reasons, we keep the ditch slope at about 0.2 m above the 9 working levels.

In the exemplary embodiment, the track structure 17 shown in FIG. Optionally, a rail 19 is attached to the base 18.

The auxiliary device shown in Figures 5 and 6, consisting of the tube laying carriages 20 and the drawbars 23 connecting them, is placed on the prepared track structure 17. Optionally, more than two tube laying trolleys 20 are placed on the track structure 17.

We did not use dewatering during the lifting of the 7th trenches, so the 7th trenches have a water level almost equal to the groundwater level 11. At this water level, the assembly bench 27, which may be formed as a float 26, which is the working level of the wire preparation, is shown in Figures 7 and 8. When multiple mounting benches 27 are used, they are connected to one another by a device similar to a draw bar 23.

9 and 10, the individual elements of the conduit section 30, optionally the tubular members 28 and the coupling members 29, are then assembled on the supports 31, optionally coupled to the shaft 38 shown in FIG. 13. and thereby providing the conductor section to be located. Optionally, the tubular members 28, the coupling members 29 and the manhole 38 may be made of plastic to form their connections by adhesive bonding. If the mounted pipe section is the beginning of the channel, the same or similar 38 shafts are installed at both ends of the pipe section. The length of the pipeline sections so installed is chosen to be the same as the mine layout plan.

Auxiliary equipment is connected to the wiring section on the assembly bench. 11, 12, and 14, the release means 35, the fastening means 36 and the guide means 37, which are directly connected to the line section. Thus, ultimately, through the auxiliary devices 35, 36 and 37, the conduit section 30 is also connected to the pipe laying carriage 20. The elastic auxiliary device, optionally a rubber ring 43, as shown in Figs. 15-16, is attached to the shaft 38 at the end of the pipeline section to be constructed.

For an intermediate pipe section, such as that shown in FIG. 13, the sheath 39 is connected to the conduit 30/2 as an auxiliary device, and as shown in the figure and above the manhole 38 at the end of the already existing conduit section 30/1. when lowered into position, the jacket 39 having an inside diameter greater than the outer diameter of the shaft 38 can move unhindered down to its intended position.

The conduit section is preferably subjected to a water tightness test even at the installation level 25. The test may be carried out, if necessary, by sealing the openings in the tube section, filling it with water, and correcting any defects after pumping or draining the water. The test may be carried out before or after mounting the auxiliary devices, as appropriate.

Then, optionally with the aid of the release device 35, as shown in Figures 9 and 10, the supports 31 are slightly raised, the floats 26 are removed with the mounting benches 27 removed from under the guide section. The guide device 37, which is connected to the guide section 30 in a manner that allows movement, is connected to the guide section 30 and the pipe laying trolley 20 during the swinging of the floaters, since the guide member 37 extends deeply into the working grooves. After connecting the auxiliary devices and removing the work bench, the line section 30 is lowered into the water. Meanwhile, it is expedient to ensure that the conduit section 30 is filled with water.

The wire section is lowered to the position C shown in Figures 13 and 14. By means of the guides 37, deviations from the direction are eliminated, thus ensuring the planned position in the horizontal sense. The clamping device 36 is used to adjust the height position because it prevents a higher position than intended, while the lowering device 35 prevents a lower position than intended. Once the design position has been adjusted, the casing 39 disposed along the shaft 38 shown in Figure 13 is also in the design position C, the inner surface being adjacent to the rubber ring 43 of the manhole prepared in accordance with Figure 15 or 16. but it just fits but doesn't connect. In the case not shown in the figures, the jacket is surrounded by a pipe clamp. This is tensioned from above by means of a pipe wrench, thereby clamping the split jacket 39 onto the shaft 38, while the jacket 39 is tensioned on the rubber ring 43, thereby creating a watertight connection between the two by deformation of the rubber ring 43 cross section. Clamping the clamp and tensioning the jacket 39 to the shaft 38 will still result in small movements of the connected and connected conductor section 30/2, after which they will be checked for their correct position, then the 35, 36, 37 directly connected and the 20 indirectly connected. auxiliary structures are secured to prevent further movement of possible forces.

We then begin embedding the laid section with sandy gravel, underwater concrete, or other suitable material having strength, or having obtained a bonding process. After embedding further movement, after reaching the position shown in FIG. 14 in the example, the connection of the auxiliary devices 35, 36, 37 to the conduit section 30 and the pipe laying trolley 20 is removed, and these auxiliary structures are recovered and preferably moved to the next section to be laid. then the workflow will be fully repaid. The mines

With the finalization of Figure 20 and the construction of the pavements, the external activity of the pipeline construction work is completed.

The internal finalization work of the embedded or substantially filled ditch will begin by establishing an interoperable connection with the previously constructed duct section. The pre-laid wiring section is closed at the end of the following section. In the embodiment shown in Fig. 1 .... 21, this end is the shaft 38. 22-23. 3 to 5, the end portion of the conduit section 30/1 extends beyond the shaft 38 and its end wall. First, water is removed from the conduit section through the manhole of the downstream section, and then an opening 50 is formed by cutting the wall of the manhole 38 shown in Figure 21. In another embodiment of the invention, an opening 50 is formed by cutting out the end wall of the 30/1 conductor section 30 shown in FIG. This makes the interlocking connection of the two wiring sections accessible from the inside. The dewatered section is checked from the inside, since the overpressure of the groundwater level 11 in the Viss filled working ditches 7 means a water tightness test circuit on the downstream pipeline section and a matched connection to the preceding section. Any defects are corrected and the wire sections are made material-dependent, depending on their material, optionally by gluing, but for other materials, by soldering or welding. Additional prefabricated elements may also be used for material continuity, as illustrated with the pipe fitting 44 shown in Figure 18. I ... 2J. In the embodiment shown in Figures 39 mantle 43 rubber ring 22 to ensure the watertight connection - as shown in Figures 23 embodiment is providing the 49 pipe element 43 rubber ring waterproofing yl ¹⁰ developed contact task ceases after making the line sections with material continuity, these auxiliary constructions become unnecessary, but the cost of their recovery would not be commensurate with their value, so they are left under the surface as a losing aid.

Many advantageous details pertaining to the substance of the process may be mentioned when using the method according to the invention or when implementing the device for carrying out the process. These include, but are not limited to, the following. It is advantageous to assemble the shaft 38 from a number of more easily movable elements. In FIG. 22, it is desirable to select a length ²⁵ extending beyond the shaft 38 of the conduit section 30/1 so that the tube member 49 is brought into the desired position when the tube member 49 is applied to the rubber ring 43 at the previous extension tube end. In order to allow later channel connections, additional manholes may be provided along with the channel section, together with the placement of a rubber ring 43 at the level of the possible connection. The shafts may also be formed as a rollover shaft as illustrated by the rubber rings 43 on two different levels shown in Figure 15.

The apparatus of the invention consists of reusable, recoverable auxiliaries and losing auxiliaries. A part ⁴⁰ of the recovered auxiliary structures reused directly connected to the conduit 30 the section 35 lebocsájtószerkezet indicated in these Figures 11 and 12, the clip structure and 37 guide structure 45 to other parts directly connected to the 30-line section, with these 20 pipe-laying carriage, the Fig. 6 is a drawbar 23 and, optionally, a movable assembly bench 27.

Some of the losing auxiliary devices have elastic properties 50, which may be the rubber ring 43 shown in Figures 21 to 23, and a solid structure, these shells 39 and tube member 49 respectively.

The embodiments described are exemplary embodiments of the process of the present invention and of the apparatus used to implement the invention, of which many other embodiments and embodiments are possible within the scope of the claims. The material of the wire can be different. The wire sections 65 can be made of crosslinked plastic, fiberglass or other reinforced plastic, steel, asbestos cement or even reinforced concrete.

Both the indicated choice of embodiments and the variety of materials that can be used show that the present invention is an advantageously applicable, widely adaptable process which, by eliminating costly groundwater level, has only a complicated, cumbersome construction process, task. The structures used can be reused, and the process, while eliminating the need for human labor at work prices, also has a favorable safety feature. However, the process can be automated, work well organized and therefore economical. Advantageously, the more important and valuable structures of the apparatus of the invention can be reused and recycled on a regular basis, and the losing structures are undemanding and costly.
