DISCONNECTION AND REPAIR METHOD OF A Clogged DRAIN PIPE

The present invention relates to a method that forms part of operations performed for the purpose of unblocking and repairing a pierced drain or sewer pipe.

Such a method is generally known. In the known method, the sewage system or drain pipe, which is mostly underground and clogged, is dug out and run through by breaking it, sawing or piercing, whereafter the dug pit and sometimes also its surroundings flood with drainage and drainage. sewage, and with the components present therein. These components not only contain bacteria and other pathogens, but sometimes also contain chemically very aggressive agents that have previously been used by residents to attempt to remove the blockage themselves. Standing in the pit flooded with polluted and environmentally harmful drainage water, the blockage must be traced further and removed, and often one or more drainage pipe parts or manifolds must be replaced and glued together. Prior to this, the contaminated drainage water is optionally suctioned off with a pump to be discharged elsewhere.

In the meantime, it may be that the pit gradually fills up with new drainage water. If the unblocking and the repairs take longer, emergency provisions must be installed or the residents must be asked not to discharge much or not at all during that time, which sometimes encounters major objections.

In addition to the aforementioned disadvantages of the known method, there is also the soil pollution, the risk of contamination with diseases or allergies, and the odor nuisance which may even persist for a long time after the silage has been closed.

The object of the present invention is to provide a cleaner, safer and faster method which does not have the aforementioned disadvantages or at least to a greatly reduced extent, and which exposes the working staff to fewer hazards and the environment to less nuisance.

To that end, the method according to the invention is characterized in that a drain pipe provided with a blockage is provided with a water-tight bottom part to be fitted behind the blockage and below the drain line, wherein at least one mounting part provided with a drill guide is provided on the bottom part, whereafter the drain pipe above the bottom part is pierced.

The method according to the invention has the advantage that the watertight bottom part, after puncturing the clogged drain line, functions as a collection tray in which the contaminated drain water running out of the drain line can flow without polluting the environment or the soil. The soil remains dry, is not polluted and this is less harmful to the environment, and it is prevented that sometimes necessary soil remediation has to be carried out in order not to commit an environmental crime. The working method thus offers the possibility of complying with the latest environmental guidelines and safety regulations for personnel. In other words, a somewhat lower level of personal protective equipment would suffice without an adverse effect for the personnel.

In addition, the personnel have the option of being able to stand in the remaining part of the pit without standing in the drain water, so that the blockage, usually with a high-pressure unclogging hose, is placed through a hole drilled in the drain pipe. acceptable way to remove.

After this or earlier, in practice at least the bottom part of the collecting bin can be sucked empty by means of a pump, and the drainage pipe that has since been cleared can be replaced or repaired.

The method according to the invention described above can advantageously be used for, among other things, houses, flats, or office buildings.

An embodiment of the method according to the invention is characterized in that the drainage water present in the bottom part is suctioned, whether or not at the command of one or more level sensors.

The advantage is that the drain water can be removed before or during the unclogging and repair process. If the method takes a longer time, the suction can be suctioned off by means of a pump conduit leading into the add-on part and / or the bottom part as a temporary provision via an operating pump, until the job can usually be completed the next day. The pump only needs to be running every now and then if it is controlled by means of one or more level sensors that monitor the level of the drainage water in the collecting basin and, when the level is too high, give the command to control means to turn the pump into operation to state.

A further embodiment of the method according to the invention is characterized in that the bottom part and the top part are watertightly connected to each other.

The advantage is that the top part can then serve as a temporary storage space for the possibly also collected drain water. The pump then has to be switched on for a shorter period of time, so that the noise thereof or of a possible aggregate is less annoying to the immediate environment. Moreover, the odor of the contaminated substance, which is therefore airtight in the collecting bin as a whole, will also be virtually absent to the environment.

Further detailed possible embodiments set out in the remaining claims are listed in the following description together with the associated advantages.

The method and the collecting system according to the present invention will now be further elucidated with reference to the figure below. Therein a schematic and non-scaled combination of possible embodiments of the collecting system according to the invention is shown, on the basis of which the corresponding method will also be explained.

The figure shows a collecting system 1 that is built up from a watertight collecting part 2 which, optionally with special means, in this case feet 3 of which one is shown, can be stably placed in a pit in the ground and can be buried if desired. As shown, the collecting part 2 has a passage or inlet 4 for receiving therein a sewer or discharge pipe 6 coming from, for example, a house 5. The blockage is in the figure to the left of the collecting part 4. The inlet 4 can be provided with a flexible grommet and / or with possible clamping members 7 for clamping the discharge pipe 6 in the inlet 4 of the collecting part 2. In principle at least a part of the collecting part 2 is made up of several separate elements or partitions to be assembled into a stable whole or to be slid together, as is shown diagrammatically.

The system 1 furthermore has an add-on part 8 to be placed on the bottom part 2, which part can be multiparted. For a sufficiently watertight seal between the parts 2 and 8 to be clamped to each other, flexible sealing members 9 are often arranged between them. In a possible, but not shown variant, the inlet 4 is situated in the boundary surface between the two parts 2 and 8. Here, the discharge line 6 can easily be laid on the top of the collecting part 2, while the collecting part 2 is arranged under the discharge pipe 6. . The collecting part 2 then does not have to be built up from individual elements on site.

The upper part of the attachment part 8 shown is provided with a drill guide 10 for guiding a drill or drill rod 11 to be arranged thereon, with which the discharge line 6 can be pierced. The contaminated waste water collected in the discharge pipe 6 initially punctures the collecting part 2 after piercing and collects therein and possibly also in the mounting part 8. The upper part of the mounting part 8 shown is provided with a connection 12 for a suction pump 13 which bin consisting of the water-tightly coupled parts 2 and 8 drains empty and carries the substance to be discharged to a storage tank 14. The storage tank 14 can be mobile and be on a vehicle.

For the purpose of simple manual placement and displacement, the attachment part 8 is provided with handles 15. This part 8 could also be provided with a lifting eye for the somewhat larger systems 1.

The interior of the collecting part 2 and / or the add-on part 8 can be provided with water level sensors to be coupled to a pump control which detect the water level and give command to the pump 13 when this level is too high and water has to be sucked out of the tank. The system 1 can have communication means (not shown) which transmit status data via GSM or E-mail coupled to the sensors, or to fault reporting sensors 35.
