[0041] The core of the present invention is to provide a slipform system and repair process for repairing in-service pipelines with water, so as to realize the overall repair of in-service pipelines with water and improve the repair efficiency.

[0042] The following will be combined with the attached Figures 1 to 10 The present invention is described in detail, and the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] It should be noted that the descriptions such as “first” and “second” used in the embodiments of the present invention are for descriptive purposes only and should not be understood as indicating or implying the number of technical features defined. Therefore, the features defined as “first” and “second” in each embodiment of this specification may indicate that at least one of the defined technical features is included.

[0044] The technical solutions of the various embodiments of the present invention described in this specification may be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in the field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that the combination of technical solutions does not exist.

[0045] Example 1.

[0046] like Figure 1-6 As shown, the present invention is a slipform system for repairing an in-service pipeline with water, which is used for repairing an in-service pipeline with water, and includes a plurality of repair modules 2, which are laid in sequence in the pipeline along the extension direction of the pipeline; a plurality of fixing components 1, each of which is connected to the repair module and is used to fix the repair module 2, and a repair gap d is provided between the repair module 2 and the inner wall of the pipeline to be repaired; a sliding track 4, which is located in the pipeline to be repaired and is slidably connected to the side of the repair module 2 away from the pipeline, and is used to transport the plurality of repair modules 2; a plugging plate 3, which is arranged at both ends of the pipeline to be repaired and is fixedly connected to the repair modules 2 located at both ends of the pipeline to form a repair station 2-d for filling with repair materials.

[0047] During the working process, the sliding track 4 is laid on the inner top wall of the pipeline to be repaired, and then the repair modules 2 are spliced ​​as a whole in the observation well in turn and hung on the sliding track 4. Each repair module 2 is pulled by an external traction device, so that the length of each repair module 2 after splicing is consistent with the length of the pipeline to be repaired, and each repair module 2 is fixedly connected to the pipeline to be repaired by a fixing component 1, and then the plugging plates 3 are installed at both ends of the repair pipeline to form a repair station 2-d. It should be noted that when installing the plugging plates 3, first install the plugging plate 3 at the upstream end of the water source to cut off the water source. When the sewage at the repair station 2-d flows out, install the plugging plate 3 at the downstream end of the water source, so that the sewage in the pipeline will not flow into the repair station 2-d, and flow from the repair module 2 to the sewage pipe formed on the side of the inner wall of the pipeline to be repaired, and then transport the repair material to the repair station 2-d through external conveying equipment. When the repair material fills the repair station 2-d, stop conveying, and then complete the repair operation of the pipeline to be repaired.

[0048] By setting up multiple groups of repair modules 2 and splicing the repair modules 2 into the repair length required for the pipeline to be repaired, the splicing method is adopted to reduce the installation difficulty of the repair modules 2, which is suitable for operations in narrow spaces such as pipe culverts.

[0049] It should be noted that the repair module 2 should match the pipe to be repaired. For example, if the cross-section of the pipe to be repaired is a square pipe, the cross-sectional shape of the repair module 2 is square; if the cross-section of the pipe to be repaired is a circular pipe, the cross-sectional shape of the repair module 2 is circular; if the pipe to be repaired has a rectangular, elliptical or other cross-sectional shape, the cross-sectional shape of the repair module 2 is adapted accordingly.

[0050] The repair module 2 should be adapted to the space of the pipeline to be repaired, and the repair gap d should be reasonably set. Take a pipeline with a circular cross-section as an example: the initial diameter of the in-service pipeline is D, and the setting of the repair gap d should meet the process standard requirements for conventional pipeline repair, such as no more than 10% of the initial pipeline diameter. The meaning of diameter reduction is the numerical value of the reduction in pipeline diameter, that is, the difference between the initial diameter of the pipeline and the diameter of the pipeline after repair.

[0051] It should be further explained that the specific value of the repair gap d is not necessarily set uniformly, that is, the value of the repair gap d on the side of the pipeline that is severely corroded should be greater than the value of the repair gap d on the other side that is severely corroded, so as to ensure that after the repair, the overall wall thickness of each side of the pipeline remains roughly the same, and the overall reduction of the repaired pipeline meets the process standard requirements for conventional pipeline repair. The degree of pipeline corrosion is judged based on the reduction value of the pipeline wall thickness.

[0052] It should be further explained that the repair gap d is the thickness of the repair structure. When the repair standard is a reduction of no more than 10% of the initial pipe diameter, the repair gap d can be a maximum of 0.05D plus the thickness lost after the original pipe is corroded and flushed with a high-pressure water gun. Furthermore, the repair gap d is also related to the strength of the repair material. The higher the strength of the repair material ratio, the smaller the repair thickness d.

[0053] Correspondingly, when the pipe to be repaired has a cross section of other shapes, the space ratio of the repair module 2 is adjusted accordingly and the repair gap d is set accordingly to match the pipe to be repaired.

[0054] In one embodiment of the present invention, a grouting part 5 is provided on one of the sealing plates 3, and a discharge part 6 is provided on the other sealing plate 3 opposite thereto, and the grouting part 5 and the discharge part 6 are both connected with the repair station 2-d; a connecting pipe 61 is provided on the discharge part 6, and the pipe mouth of the connecting pipe 61 is vertically upward.

[0055] During the repair process, external conveying equipment conveys the material used to repair the pipeline to the repair station 2-d through the grouting part 5, and allows the repair material to flow and fill the entire repair station 2-d.

[0056] It should be noted that the external conveying device may be a pressure pump, which applies pressure to the repair material to achieve the conveying of the repair material.

[0057] When the repair material is discharged from the discharge portion 6, it indicates that the entire repair station 2-d has been filled with the repair material.

[0058] It should be noted that, during installation, the grouting part 5 and the discharge part 6 are both located at the top of the plugging plate 3, that is, at the side close to the ground surface. The grouting part 5 is set at the top of the plugging plate 3, which facilitates the connection with the external feeding mechanism. The discharge part 6 is set at the top of the plugging plate 3. Furthermore, a connecting pipe 61 is sleeved at the end of the discharge part 6, and the mouth of the connecting pipe 61 is vertically upward. When the repair material overflows from the mouth of the connecting pipe 61, it is ensured that the repair material can fill the entire repair station 2-d. At the same time, it is also convenient for the staff to observe from the ground. When the repair material fills the entire repair station 2-d, the external conveying equipment can be closed in time to reduce the waste of repair materials.

[0059] Furthermore, a sensor may be provided on the discharge portion 6, and the sensor is connected to communicate with an external feeding mechanism. When the sensor senses that the repair material overflows from the discharge portion 6, a signal is transmitted to an external conveying device to stop feeding. It should be noted that the selection of sensors and signal sources are all existing technologies, so they will not be elaborated here.

[0060] In this embodiment, each group of the repair modules 2 includes at least two modules 21 and a support frame 212 for connecting the modules 21 .

[0061] In the specific implementation process, the specific number of the mold pieces 21 constituting a repair module 2 can be 2, 3, 4 or any number, and the specific number is determined according to the construction standard, manufacturing difficulty and production cost in the actual construction process. The splicing method is adopted to facilitate the installation of the repair module 2 in the pipeline to be repaired, reduce the repair difficulty and reduce the pipeline repair cost.

[0062] It should be noted that the length of each support frame 212 is consistent with the length of the mold piece 21, and the cross-sectional shape of the support frame 212 matches the cross-sectional shape of the pipeline to be repaired.

[0063] During the specific installation process, the support frame 212 is first transported to the observation well, and then each mold 21 is installed on the support frame 212. During installation, the mold 21 can be spliced ​​to the various positions of the support frame 212 for installing the mold 21 by a robot, or the support frame 212 can be rotated so that the various positions for installing the mold 21 are facing the direction in which the mold 21 is transported to the observation well, thereby facilitating the installation of the mold 21.

[0064] In this embodiment, each mold piece 21 includes a template 211, and each of the templates 211 is connected to the support frame 212 via an adjustable support assembly 7. The adjustable support assembly 7 includes a telescopic rod 71, and the telescopic rod 71 has a fixed end and a movable end. The fixed end is fixedly connected to the support frame 212, and the movable end abuts against the template 211.

[0065] By setting the adjustable support assembly 7, the template 211 can be supported, and then during the repair process, the repair material can be supported, thereby improving the repair effect of the pipeline.

[0066] Specifically, if the shape of the pipe to be repaired is square, the movable end of the telescopic rod 71 is perpendicular to the surface of the corresponding template 211; if the shape of the pipe to be repaired is circular, the movable end of the telescopic rod 71 is perpendicular to the tangent of the highest point of the arc of the template 211.

[0067] It should be noted that, in the present invention, the adjustment support assembly 7 adopts hydraulic adjustment, so as to improve the support capacity of the telescopic rod 71 and further improve the stability of the telescopic rod 71 .

[0068] In this embodiment, the sealing plate 3 is fixedly connected to the inner wall of the pipe to be repaired, and is also fixedly connected to the repair modules 2 located at both ends of the pipe to be repaired. A sealing strip is also provided on the side of the sealing plate 3 located outside the repair station 2-d, so that the sealing plate 3 fits tightly against the inner wall of the pipe, thereby improving the sealing of the repair station 2-d.

[0069] Furthermore, sealing strips are provided at the joints of the repair modules 2 to improve the sealing performance of the repair modules 2 after being spliced.

[0070] In this embodiment, each of the fixing components 1 includes a plurality of pads 11, each of which is evenly fixed on the inner wall of the pipe to be repaired; an adjusting bolt 12, the adjusting bolt 12 passes through the repair module 2 and is connected to the pad 11, and the thickness of the pad 11 is smaller than the repair gap d.

[0071] Specifically, at the end of each template 211, a connecting hole is opened along the thickness direction of the template 211. When the repair module 2 is installed in sequence, the adjusting bolt 12 passes through the connecting hole and is threadedly connected to the corresponding pad 11, thereby fixing the repair module 2 and the pipeline to be repaired. Furthermore, the thickness of the pad 11 is smaller than the repair gap d, so that the repair module 2 will not contact the pad 11 during the pulling process of the traction equipment, thereby not hindering the movement of the repair module 2 during the installation process.

[0072] Furthermore, after all the repair modules 2 are installed in sequence, by fine-tuning each adjusting bolt 12, the overall repair module 2 can maintain a high degree of concentricity and coaxiality with the pipeline to be repaired, so that the actual value of the repair gap d is consistent with the set value, thereby improving the repair effect.

[0073] The repair module 2 is fixed by threading the adjusting bolt 12 and the pad 11, which can reduce production costs and improve the bearing capacity and overall stability of the repair module 2, thereby being able to repair longer in-service pipelines.

[0074] In this embodiment, a pipe sheet 213 is further provided on the side of the support frame 212 facing away from the template 211 .

[0075] After each group of the repair modules 2 is spliced, each of the pipe segments 213 forms a sewage conduit 8, and the diameter of the sewage conduit 8 gradually increases along its length. It should be noted that both ends of each pipe segment 213 extend to the outside of the support frame 212, and the length of the pipe segment 213 is slightly greater than the length of the support frame 212, thereby facilitating subsequent splicing and improving the sealing of the sewage conduit 8.

[0076] By setting the diameter of the sewage conduit 8 to be gradually expanded, the overall splicing of the sewage conduit 8 is more compact when the repair module 2 is spliced, and the sealing of the connection is better, thereby preventing the leakage of flowing water in the sewage conduit 8 and improving the practicality of the present invention.

[0077] Example 2.

[0078] like Figure 7-10 As shown, the present invention is a slipform system for repairing an in-service pipeline with water, which is used for repairing an in-service pipeline with water, and includes a plurality of repair modules 2, which are laid in sequence in the pipeline along the extension direction of the pipeline; a plurality of fixing components 1, each of which is connected to the repair module and is used to fix the repair module 2, and a repair gap d is provided between the repair module 2 and the inner wall of the pipeline to be repaired; a sliding track 4, which is located in the pipeline to be repaired and is slidably connected to the side of the repair module 2 away from the pipeline, and is used to transport the plurality of repair modules 2; a plugging plate 3, which is arranged at both ends of the pipeline to be repaired and is fixedly connected to the repair modules 2 located at both ends of the pipeline to form a repair station 2-d for filling with repair materials.

[0079] In this embodiment, each repair module 2 includes at least two templates 211 .

[0080] In the specific implementation process, the specific number of templates 211 constituting the repair module 2 can be 2, 3, 4 or any number, and the specific number is determined according to the construction standard, manufacturing difficulty and production cost in the actual construction process. The splicing method is adopted to facilitate the installation of the repair module 2 in the pipeline to be repaired, reduce the difficulty of repair, and reduce the cost of pipeline repair.

[0081] The fixing assembly 1 comprises a mounting frame 15, which is coaxially arranged in the pipeline to be repaired, and the sliding track 4 is fixedly arranged on the mounting frame 15. It should be noted that the shape of the mounting frame 15 matches the pipeline to be repaired.

[0082] Compared with Example 1, by installing the mounting frame 15 separately in the pipeline to be repaired, and placing the repair module 2 on the sliding rail 4, the repair module 2 is supported. This operation method facilitates the splicing of the repair modules 2 and the laying of each repair module 2 in the pipeline, and is suitable for short-distance pipeline repair.

[0083] After the repair modules 2 are placed on the sliding rails 4, the repair modules 2 are pulled by external traction equipment so that each repair module 2 reaches the required repair length of the pipeline to be repaired.

[0084] A sewage pipe 8 is arranged on the side of the mounting frame 15 facing away from the pipe to be repaired, and a plurality of adjustment support assemblies 7 are arranged on the side of the mounting frame 15 facing the pipe to be repaired, each of the adjustment support assemblies 7 is evenly arranged on the support frame 1 along the length direction of the pipe; each of the adjustment support assemblies 7 includes a plurality of telescopic rods 71, and the working end of each of the telescopic rods 71 ​​is vertically facing the corresponding mold 21.

[0085] By setting the adjustable support assembly 7, the repair module 2 as a whole is supported, and then the repair material is supported, so that the bearing capacity of the repair module 2 is improved, thereby improving the repair effect of the pipeline.

[0086] Specifically, if the shape of the pipe to be repaired is square, the working end of the telescopic rod 71 is perpendicular to the surface of the corresponding template 211. If the shape of the pipe to be repaired is circular, the working end of the telescopic rod 71 is perpendicular to the tangent of the highest point of the arc of the template 211.

[0087] In this embodiment, the sealing plate 3 is provided with a positioning buckle 31 for fixing the relative position between the repair pipe and the sealing plate 3. The positioning buckle 31 is used to fix the repair module 2 spliced ​​into the required length as a whole to prevent the repair module 2 from moving left and right, and at the same time make the sealing plate 3 fit tightly against the inner wall of the pipe, thereby improving the sealing performance of the repair station 2-d.

[0088] Furthermore, sealing strips are provided at the connections of the repair modules 2 to improve the sealing of the repair modules 2 after splicing. In addition, sealing strips are also provided on the side of the sealing plate 3 located outside the repair station 2-d to prevent the repair material from overflowing from the gap.

[0089] A second aspect of the present invention provides a repair process for repairing an in-service pipeline with water using the slipform system described in the first aspect, comprising the following steps:

[0090] S1. Clean the surface of the pipeline to be repaired;

[0091] S2. Fixed sliding track 4;

[0092] S3. Apply anti-corrosion coating on the side of the mold 21 facing the pipe to be repaired;

[0093] S4. The mold pieces 21 are sequentially transported to the observation well at one end of the repair pipeline by a conveying device, and the mold pieces 21 are spliced ​​into a repair module 2 by a manipulator;

[0094] S5. The repair module 2 is placed on the sliding track 4 by a manipulator.

[0095] S6. The repair module 2 is transported to the other end of the repair pipe by a traction device, and the above S3-S5 are repeated in sequence until the length of each repair module 2 is consistent with the length of the pipe to be repaired;

[0096] S7. Install the plugging plate 3 on both sides of the pipe to be repaired, and seal the connection of the plugging plate 3;

[0097] S8. The external feed pump delivers the repair material to the repair station 2-d through the feed section. When the repair material is discharged from the discharge section 6, the delivery is stopped;

[0098] S9. After maintenance, the blocking plate 3 is removed and the repair module 2 is taken out by a traction device.

[0099] In step 1, the specific operation of cleaning the surface of the pipe to be repaired is to use a pipeline robot or other mobile equipment, carrying a high-pressure water gun, to spray and wash the inner wall of the pipe to be repaired. It should be noted that the main purpose of this step is to remove the stain layer accumulated on the inner wall of the pipe over the years and to remove rust on the surface of the pipe. Therefore, there is no need to intercept the pipe, and the material that falls off after cleaning can flow out of the pipe to be repaired with the water flow; thereby ensuring that the surface of the pipe to be repaired meets the Sa2.5 standard.

[0100] In step 3, the outer walls of the mold 21 corresponding to the repair station 2-d are coated with corrosion-resistant material, which is a permeable solvent-free epoxy sealing coating with a coating thickness of more than 0.2 mm. By adding the permeable solvent-free epoxy sealing coating, the permeable solvent-free epoxy sealing coating can be combined with the repair material in the subsequent repair process to form an anti-corrosion surface of the repair structure. At the same time, by adding the permeable solvent-free epoxy sealing coating, the repair structure and the mold 21 can be quickly demolded after the repair is completed, thereby improving the practicality of the present invention.

[0101] The above description is only a preferred embodiment of the present invention, and does not limit the patent protection scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
