Definitions
- the present invention relates to a method for lining a pipeline or a pipe
- US-A-4368 091 discloses a method for lining the inner surface of a pipeline with a flexible, tubular, orange lining material using a liquid resin serving as an adhesive. This procedure has the following steps:
- the aim of this known method is to use hoses as long as possible as lining materials so that as little access as possible to the interior of the pipeline or the channel has to be created. It is already possible to insert hoses of more than 500 m in length into the pipes or ducts. However, this is a process that lasts several hours, with filling and distributing the adhesive alone (about 1000 kg with a nominal diameter of DN 300 and a renovation length of 600 m) over an hour, and the mean feed speed of the hose is about six meters per minute. The adhesive used must be processable until the completion of the lining process, ie have a pot life (duration of processability) of several hours.
- the curing time for cold curing is usually at least five times the pot life, so that the pressure medium must remain in the hose for more than a full day until the adhesive has cured sufficiently. Since normal operation must be interrupted during this period when a pipeline or sewer is renovated, this can be associated with considerable operational restrictions. Shortening the hardening time by heating the pressure medium is complex and, at least when renovating steel pipelines, also problematic insofar as the pipeline should not be heated to temperatures above 30 ° C, since otherwise heat fractures can result in weld seam breaks and external bituminous Corrosion coatings can be damaged. With pipelines with long lengths and large diameters there are almost insurmountable technical difficulties.
- an adhesive which adheres to the inner wall of the pipeline or the channel by means of a woven fabric, braid, knitted fabric, felt, knitted fabric or fleece
- the inventive method according to a first aspect has the following steps:
- the hose Sufficient time for the hose to adhere to the inner wall of the pipeline or the duct in order to be able to do without the internal pressure applied by the pressure medium.
- the pipeline or the duct can thus be put back into operation while the adhesive is still curing with a long pot or curing time.
- the operating pressure in the pipeline can also provide support until the adhesive has fully cured with a long pot life.
- the method according to a second aspect of the invention uses a slyer consisting of a fully saturated fabric, mesh, knitted fabric, felt, knitted fabric or fleece and has the steps:
- this method uses a hose made of fully impregnated tissue or the like, it is not necessary for the tissue to be soaked in the pipeline before the hose is inserted, in order to avoid air pockets in the tissue after the hose is fastened to the inner wall of the pipeline , It is therefore sufficient to use only the adhesive with a short curing time in order to obtain a firm and homogeneous connection between the pipeline and the hose.
- a pressure-resistant barrier layer is preferably applied to the inner side of the hose after the introduction, before or after the introduction. This makes it possible to carry out the pressing of the hose and, if the barrier layer was carried out before the hose was introduced, the inversion of the hose under higher pressure.
- the method according to a third aspect of the invention uses a coated fabric Braided knitted fabric, felt, knitted fabric or fleece existing hose and has the steps:
- the exercise of a sufficiently high pressure when pressing the hose makes the previous full-volume impregnation of the tissue or the like with an adhesive with a long pot life or other material unnecessary, in order to ensure a firm, air-free connection between the pipeline and the hose by means of the briefly curing adhesive.
- the adhesive is printed in all voids of the fabric.
- a vacuum can be generated in the part of the pipeline that has not yet been lined to suck air out of the tissue.
- the method according to the fourth aspect of the invention also uses a tube consisting of a coated fabric, braid, knitted fabric, felt, knitted fabric or fleece and has the steps: filling in a metered amount of an adhesive under conditions in which the adhesive hardens not yet taking place, the hose is evenly distributed over the length of the hose,
- This method has the advantage that an adhesive with a long pot life is not required and that no special requirements have to be made regarding the timing of the process.
- the adhesive can be inserted into the tubing at any time before the tubing is inserted.
- a particularly advantageous embodiment of this method consists in that an adhesive which cures under anaerobic conditions and upon contact with metal is used, which is applied to the inner wall of a pipeline or a duct made of metal. This is where the curing begins immediately after the everted hose has been brought into contact with the inner wall of the pipe and the air in the hose has pressed the air out of the gap between the hose and the pipe so that only the adhesive remains in it.
- Further training consists in the use of a multi-component adhesive, of which at least one component is applied to the inner wall of the pipeline before the hose is inserted and the remaining components are filled in before the hose is inserted, or in the use of a multi-component adhesive. of which at least one component is enclosed in microcapsules which are destroyed on the outside of the everted tube.
- the method according to the fifth aspect of the invention also uses a tube consisting of a coated fabric, braid, knitted fabric, felt, knitted fabric or fleece and has the steps: filling in a metered amount of an adhesive under conditions in which the adhesive hardens takes place with a long curing time, in the hose in an even distribution over the length of the hose, introducing the hose into the pipeline or the channel, one end of the hose being held at the end of the pipeline or the channel in the direction of movement of the hose and the hose being pressurized below Inverted into the pipeline or channel, creating the conditions for that located on the outside of the inverted part of the hose Adhesive to cure in a short time and generating an internal pressure in the inserted hose to press it against the inner wall of the pipeline or the duct until the adhesive between the hose and the inner wall of the pipeline or the duct has hardened.
- This method has the advantage that an adhesive with a short pot life is not required and that there are no special requirements for the timing of the process.
- the adhesive can be introduced into the hose in the usual time before the hose is inserted into the pipeline. There is a wide time frame for creating the conditions for shortening the curing time.
- a particularly advantageous measure to accelerate the hardening consists in irradiating the adhesive with microwaves.
- the curing time of the adhesive with a short curing time can range from one minute to six hours; however, it should be as short as possible and, for procedural reasons, should preferably be about 30 minutes. It is therefore expedient to keep the time interval between the start of curing of this adhesive and the pressing of the hose against the inner wall as short as possible. When using a metal pipeline, this can expediently be carried out using an anaerobic adhesive which, after being applied to the inner wall, only begins to harden when contact with oxygen is prevented by pressing on the hose. Another approach is to use a multi-component adhesive OJ t
- the pipe 3 consisting of metal, preferably steel, gray cast iron or ductile gray cast iron, plastic, preferably PVC or GFRP (glass fiber reinforced plastic), or mineral material, preferably asbestos cement, stoneware, fiber cement, concrete, reinforced concrete or masonry, opens at the construction pit 2 opposite end into a target pit 8.
- a mobile robot 10, 11 which is battery-operated and therefore not Supply lines required.
- the robot 10, 11 is provided with a sandblasting device and an adhesive spraying device.
- the robot 10, 11 drives through the pipe 3 exposed at both ends and cleans it, e.g. by sandblasting. Any unevenness or cavities can be removed with a spatula.
- an adhesive with a pot life in the range between one and six hours, which essentially depends on the length of the tube is poured into the fabric tube 4 and evenly distributed along its length. Then the retention band 5 and then the fabric hose L m of the rotating drum 1 are wound up.
- the beginning of the fabric hose 4 is attached to a reversing head 12 attached to the rotary drum 1 and then the fabric hose 4 is pressed outwards by the air pressure prevailing in the rotary drum 1, whereby it is turned inside out at the same time.
- the advancing end of the everted fabric hose 4 is inserted into the pipeline 3.
- the inside of the fabric hose 4 is turned outwards, so that the plastic layer is on the side facing the tube inside and the adhesive is on the side of the fabric tube facing the tube wall.
- the retention band 5 ensures a controlled forward movement of the tissue tube 4 when it is pressed in, in order to ensure that the
- Adhesive is distributed evenly between the fabric hose 4 and the pipeline 3 and the fabric hose 4 is pressed onto the pipeline wall without wrinkles.
- the robot 10, 11 is used to apply a quick-setting adhesive with a curing time of approximately 30 minutes to the inner wall of the pipeline 3, immediately before the fabric hose 4 is pressed against the inner wall.
- the robot 10, 11 is filled, for example, in the target pit 8 with the adhesive and then moves to shortly before the end 9 of the fabric hose 4.
- the robot 10, 11 then begins, with the aid of its spraying device, the adhesive over the entire circumference of the inner wall of the Apply pipeline 3 evenly to it, moving back at the same speed at which the end 9 of the fabric hose 4 is fed, so that the distance between the robot 10, 11 and the end 9 remains the same.
- the robot 10, 11 is expediently provided with, for example, an ultrasonic measuring device, so that on the basis of the measured distance the speed of the robot 10, 11 is controlled so that this distance remains constant.
- This distance is chosen so that it is the highest corresponds within a few minutes to the distance covered by the hose end 9, ie the hose end 9 always reaches the quick-setting adhesive before its pot life has elapsed.
- the fast-hardening adhesive only insignificantly penetrates the tissue from the inner wall of the pipeline 3. However, this is sufficient to hold the fabric hose 4 on the inner wall of the pipeline 3 after the quick-setting adhesive has hardened.
- the pressure generated by the air compressor 7 inside the fabric hose 4 therefore only needs to be maintained after it has reached the end of the pipeline 3 of the target construction pit 8 until the fast-curing adhesive has cured.
- the rotary drum 1 can then be uncoupled from the inserted fabric hose 4 and then put back into operation for a next refurbishment process long before the slowly hardening adhesive has hardened.
- the internal pressure prevailing during normal operation of the pipeline additionally presses the fabric hose 4 against the inner wall of the pipeline 3.
- the robot consists of two carriages 10 and 11 coupled to one another.
- the carriage 10 serves as a drive device and is equipped in such a way that it can be coupled to one of several different carriages.
- These trolleys are used to carry out various measurement, inspection or work processes such as distance, thickness or caliber measurements, investigations of the pipe / hose connection for cavities (bedding conditions) using ultrasound, investigations using a television camera, cleaning work with High water pressure, suction work with negative pressure, sandblasting work, milling work, spatula work, spraying or Coating work, winding work and the like. Pure container wagons are also possible, for example filled with cleaning or coating agents. In this case, the container car and the associated work car are pulled or pushed together by the drive car through the pipeline 3.
- the corresponding carriage is pulled out of the drive carriage 10 on the pipeline 3 or pushed out and uncoupled.
- the car (s) required for the next measuring or working process is / are coupled and pulled or pushed through the pipeline 3 at the appropriate speed in order to carry out the process.
- the pipeline 3 has a correspondingly large diameter, manned wagons can also be pulled or pushed through it. the .
- the exemplary embodiment shown relates to the first aspect of the present invention.
- aspects of the invention essentially uses the same device; However, in the second and third aspects there is no need to fill adhesive with a long pot life into the hose before the inverting process and in the fourth and fifth aspect there is no adhesive to be applied to the inner wall of the pipeline.
- a fabric hose soaked in volume with a resin or the like is also used, while in the method according to the third aspect the same hose can be used as in the method according to the first aspect.
