Description

Technical Field

[0001] This invention relates to the field of pipeline maintenance technology, and in particular to a method for reinforcing a thin-walled stainless steel inner lining with internal reinforcement structure for water supply network repair. Background Technology

[0002] With the rapid pace of urbanization, water supply networks are closely linked to people's lives and work, shouldering important functions such as urban water supply. However, due to various reasons, water supply pipelines in many Chinese cities suffer from varying degrees of damage. Failure to repair them in a timely manner may lead to pollution or road collapses, endangering traffic safety and the lives and property of citizens.

[0003] In existing technologies, water supply pipe repairs often involve internal lining reinforcement, external reinforcement, or simultaneous internal and external reinforcement. For internal lining reinforcement, some methods involve driving the lining pipe into the old pipe using impact, thus repairing the damaged pipe. However, this method not only increases the workload for workers but also easily damages the lining pipe, affecting its lifespan and making it unusable. To address these shortcomings, this invention discloses a method for reinforcing water supply networks with a thin-walled stainless steel lining and internal reinforcement structure, thus resolving the aforementioned problems. Summary of the Invention

Limiting plates matching the limiting grooves are installed on the sides of the two movable plates that are close to each other. Elastic compression mechanisms are installed on the sides of the two movable plates that are far apart from each other. Trapezoidal movable blocks are installed on the sides of the two movable plates. A movable hole is formed on the inner side wall of the fixed groove, and a movable column is slidably installed in the movable hole. A trapezoidal pressing block is installed at one end of the movable column near the two trapezoidal movable blocks. A movable groove is formed on the side of the right incomplete liner tube, and a pressing plate is installed at the other end of the movable column into the movable groove. An elastic reset mechanism is installed on the side of the pressing plate. An annular sliding groove is formed on the side of the right incomplete liner tube, and two annular sliding rods are installed on the opposite inner walls of the annular sliding groove. An annular slider is slidably installed on both annular sliding rods. An annular sealing plate is installed on the outer wall of the annular slider. A sealing groove adapted to the annular sealing plate is opened on the side of the left incomplete inner liner tube. An annular adjusting plate and a connecting plate are respectively installed on the mutually distant sides of the annular slider. An annular clearance groove is opened on the mutually distant side of the right incomplete inner liner tube. The annular adjusting plate and the connecting plate pass through two annular clearance grooves respectively. Multiple fixing holes are opened on the inner wall of one of the annular clearance grooves. A fixing mechanism adapted to the fixing holes is provided on the annular adjusting plate.

[0006] Preferably, the fixing mechanism includes a movable cavity formed on the annular adjusting plate, a movable plate slidably installed in the movable cavity, a fixing post adapted to the fixing hole installed on the top of the movable plate, a pressure rod installed on the top of the movable plate, the top end of the pressure rod extending to the outside of the movable cavity and having a circular plate installed thereon, and an elastic pressing mechanism installed on the bottom of the movable plate.

[0007] Preferably, the elastic pressing mechanism includes two compression springs installed at the bottom of the movable plate, and the other ends of the two compression springs are installed on the bottom inner wall of the movable cavity.

[0008] Preferably, two guide rods are installed on the opposite inner walls of the movable cavity, and two guide holes are opened on the top of the movable plate, with the two guide rods passing through the two guide holes respectively.

[0009] Preferably, the elastic compression mechanism includes two compression springs mounted on the top of the movable plate. Preferably, the elastic reset mechanism includes a reset spring mounted on the side of the pressing plate, and the other end of the reset spring is mounted on the inner side wall of the movable groove.

[0010] Preferably, the annular sealing plate has a U-shaped groove on its peripheral inner wall, and an inflatable airbag is installed on the top inner wall of the U-shaped groove. The inflatable airbag is provided with an inflation port and an air outlet.

[0011] Preferably, sealing strips are installed on the side of both the left incomplete inner liner tube and the right incomplete inner liner tube.

[0012] Preferably, both the annular adjusting plate and the connecting plate are equipped with annular baffles on their sides.

[0013] Preferably, a method for using a thin-walled stainless steel inner lining reinforcement structure for water supply network repair includes:

[0014] S1. When using, first place the left incomplete inner liner tube and the right incomplete inner liner tube into the old pipe. Use the pressing plate, trapezoidal extrusion block, and trapezoidal moving block to move the two moving plates away from each other. Then insert the fixing plate on the left incomplete inner liner tube into the fixing groove and align the limiting groove with the limiting plate. Then release the pressing plate. Under the action of the return spring, the trapezoidal extrusion block will return to its original position. Under the elastic action of the extrusion spring, the limiting plate will be fixed to the fixing plate.

[0015] S2. After it is fixed, press the round plate. The round plate moves the movable plate through the pressure rod. The movement of the movable plate will drive the fixed column to move, thereby removing the fixed column from the fixing hole. At this time, move the annular adjustment plate. The movement of the annular adjustment plate will drive the annular sealing plate to move through the annular slider. When it moves to the designated position, release the round plate. Under the action of the compression spring, the movable plate will be reset, thereby fixing the annular slider and thus initially sealing the left and right incomplete inner liner tubes.

[0016] S3. After the initial sealing is completed, inflate the expansion bladder through the inflation port to make it expand, and under the action of the annular baffle, seal the left and right incomplete inner liner tubes.

[0017] S. Then, waterproof sealant is injected through the grouting port to completely seal the left and right incomplete inner lining pipes with the original pipe.

[0018] In summary, the technical effects and advantages of this invention are as follows:

[0019] 1. In this invention, during use, the left and right incomplete inner lining tubes are first placed into the old pipe. After placement, the pressing plate is pressed, causing the trapezoidal extrusion blocks to move, which in turn extrudes the two trapezoidal moving blocks, causing the two limiting plates to move away from each other. Then, the fixing plate on the left incomplete inner lining tube is inserted into the fixing groove, aligning the limiting groove with the limiting plate. Once aligned, the pressing plate is released, and under the action of the return spring, the pressing plate returns to its original position. At this point, under the elastic action of the four extrusion springs, the two limiting plates move closer together, thus fixing the limiting plates to the fixing plate. After fixing... Then, the fixing mechanism releases the ring adjusting plate, and the ring adjusting plate is moved. The ring adjusting plate moves and drives the ring sealing plate to move through the ring slider. When it moves to the designated position, it is fixed by the fixing mechanism, thus achieving a preliminary seal. At this time, the expansion airbag is inflated through the air inlet, and under the action of the ring baffle, the seal of the left and right incomplete inner lining tubes is strengthened. Then, the waterproof sealant is injected through the grouting port, thus achieving a complete seal with the original pipeline. Finally, it is reinforced with stainless steel strips, so that reinforcement and repair can be carried out without hammering, making it easy to use.

[0020] 2. In this invention, the annular baffle provides a certain degree of obstruction to prevent leakage during grouting. The sealing strip enhances the sealing effect and prevents leakage from the left and right incomplete inner lining tubes during use.

[0021] 3. In this invention, the expansion bladder, inflation port, and air outlet facilitate enhanced sealing between the left and right incomplete inner liner tubes, preventing leakage during use and simplifying operation. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0031] Example: Reference Figure 1-6The method for reinforcing a water supply network with a thin-walled stainless steel lining and internal reinforcement structure is shown. It includes a left incomplete lining pipe 1 and a right incomplete lining pipe 2. Multiple stainless steel strips 13 are installed on the outer periphery of both the left and right incomplete lining pipes. Four fixing plates 14 are installed on the outer periphery of both pipes. A silicone strip 15 is provided between every two matching fixing plates 14. Each of the four fixing plates 14 has a grouting port 16 on its side. A fixing plate 3 is installed on the side wall of the incomplete inner liner tube 1. Limiting grooves are formed at the top and bottom of the fixing plate 3. A fixing groove is formed on the side of the right incomplete inner liner tube 2. Two limiting rods 4 are installed on the opposite inner walls of the fixing groove. Two movable plates 5 are slidably mounted on the two limiting rods 4. Limiting plates 6 matching the limiting grooves are installed on the sides of the two movable plates 5 that are close to each other. Elastic compression mechanisms are installed on the sides of the two movable plates 5 that are far apart from each other. Trapezoidal movable blocks 8 are installed on the sides of the two movable plates 5. The side of the fixing groove... The wall has a movable hole, and a movable column 9 is slidably installed in the movable hole. A trapezoidal pressing block 10 is installed at one end of the movable column 9 near the two trapezoidal movable blocks 8. A movable groove is opened on the side of the right incomplete inner liner tube 2. The other end of the movable column 9 extends into the movable groove and is installed with a pressing plate 11. An elastic reset mechanism is installed on the side of the pressing plate 11. An annular sliding groove is opened on the side of the right incomplete inner liner tube 2. Two annular sliding rods 17 are installed on the opposite inner walls of the annular sliding groove. An annular slider 18 is slidably installed on both annular sliding rods 17. An annular sealing plate 19 is installed on the outer periphery of the annular slider 18. A sealing groove adapted to the annular sealing plate 19 is opened on the side of the left incomplete inner liner tube 1. An annular adjusting plate 21 and a connecting plate are respectively installed on the mutually distant sides of the annular slider 18. An annular clearance groove is opened on the mutually distant sides of the right incomplete inner liner tube 2. The annular adjusting plate 21 and the connecting plate pass through the two annular clearance grooves respectively. Multiple fixing holes are opened on the inner periphery of one of the annular clearance grooves. A fixing mechanism adapted to the fixing holes is provided on the annular adjusting plate 21.

[0032] Using the above mechanism, in use, first, the left incomplete inner liner tube 1 and the right incomplete inner liner tube 2 are placed into the old pipe. After placement, press the pressing plate 11. The pressing plate 11 moves, causing the moving column 9 to move. The moving column 9 moves, causing the trapezoidal extrusion block 10 to move. When the inclined surface of the trapezoidal extrusion block 10 contacts the two trapezoidal moving blocks 8, the trapezoidal extrusion block 10 continues to move and extrudes the two trapezoidal moving blocks 8. Under the action of the limiting rod 4, the two moving plates 5 move away from each other, and then the two limiting plates 6 move away from each other. At this time, the fixing plate 3 on the left incomplete inner liner tube 1 is inserted into the fixing groove, and the limiting groove is aligned with the limiting plate 6. After alignment, the pressing plate 11 is released. Under the action of the elastic reset mechanism, the pressing plate 11 is reset. The reset of the pressing plate 11 will cause the trapezoidal extrusion block 10 to reset. The reset of the trapezoidal extrusion block 10 does not... The trapezoidal moving block 8 is then squeezed, causing the two moving plates 5 to approach each other under the elastic action of the elastic squeezing mechanism, thereby fixing the limiting plate 6 to the fixing plate 3. After fixing, the fixing mechanism is used to release the ring adjusting plate 21, and then the ring adjusting plate 21 is moved. The ring adjusting plate 21 moves, driving the ring slider 18 to move. The ring slider 18 moves, driving the ring sealing plate 19 to move. When it moves to the designated position, the fixing mechanism fixes the ring slider 18, thereby initially sealing the left incomplete inner lining tube 1 and the right incomplete inner lining tube 2. At this time, the waterproof sealant is injected through the grouting port 16, thereby completely sealing the left incomplete inner lining tube 1 and the right incomplete inner lining tube 2 with the original pipe. At this time, the stainless steel strip 13 is used for reinforcement. Thus, the reinforcement and repair can be carried out without hammering, making it easy to use.

[0033] like Figure 6 As shown, the fixing mechanism includes a movable cavity opened on the annular adjusting plate 21, a movable plate 23 slidably installed in the movable cavity, a fixing post 26 adapted to the fixing hole installed on the top of the movable plate 23, a pressure rod 27 installed on the top of the movable plate 23, the top end of the pressure rod 27 extends to the outside of the movable cavity and is fitted with a circular plate 28, and an elastic pressing mechanism is installed at the bottom of the movable plate 23. The advantage of this arrangement is that the annular adjusting plate 21 can be easily fixed by the arrangement of the movable plate 23, the fixing post 26, the pressure rod 27 and the circular plate 28, thereby preventing the annular sealing plate 19 from moving.

[0034] like Figure 6 As shown, the elastic pressing mechanism includes two compression springs 25 installed at the bottom of the movable plate 23. The other end of the two compression springs 25 is installed on the bottom inner wall of the movable cavity. The advantage of this arrangement is that, by setting the compression springs 25, when the circular plate 28 is not pressed, the movable plate 23 is reset under the action of the compression springs 25, thereby resetting the fixed column 26.

[0035] like Figure 6As shown, two guide rods 24 are installed on the inner walls of the movable cavity, and two guide holes are opened on the top of the movable plate 23. The two guide rods 24 pass through the two guide holes respectively. The advantage of this arrangement is that the movable plate 23 can move horizontally through the guide rods 24.

[0036] like Figure 3 As shown, the elastic compression mechanism includes two compression springs 7 installed on the top of the moving plate 5. The other end of the two compression springs 7 is installed on the top inner wall of the fixed groove. The advantage of this arrangement is that, by setting the compression springs 7, when the trapezoidal compression block 10 does not compress the trapezoidal moving block 8, the two moving plates 5 are brought closer to each other under the elastic action of the four compression springs 7.

[0037] like Figure 3 As shown, the elastic reset mechanism includes a reset spring 12 installed on the side of the pressing plate 11. The other end of the reset spring 12 is installed on the inner wall of the side of the moving groove. The advantage of this arrangement is that, by setting the reset spring 12, when the pressing plate 11 is not pressed, the pressing plate 11 is reset under the action of the reset spring 12.

[0038] like Figure 2 As shown, a U-shaped groove is provided on the inner wall of the annular sealing plate 19. An expansion airbag 20 is installed on the top inner wall of the U-shaped groove. The expansion airbag 20 is provided with an inflation port and an air outlet. The advantage of this arrangement is that the expansion airbag 20, the inflation port and the air outlet facilitate the strengthening of the sealing between the left incomplete inner liner tube 1 and the right incomplete inner liner tube 2, making it convenient to use.

[0039] like Figure 1 As shown, sealing strips 29 are installed on the side of both the left incomplete inner liner tube 1 and the right incomplete inner liner tube 2. The advantage of this setting is that the sealing strips 29 increase the sealing effect and prevent leakage from occurring in the left incomplete inner liner tube 1 and the right incomplete inner liner tube 2 during use.

[0040] like Figure 1 As shown, both the annular adjusting plate 21 and the connecting plate are equipped with annular baffles 22 on their sides. The advantage of this arrangement is that the annular baffles 22 provide a certain degree of obstruction, preventing leakage during grouting.

[0041] A method for using a thin-walled stainless steel inner lining reinforcement structure for water supply network repair, the method comprising:

[0042] S1. When in use, first put the left incomplete inner liner tube 1 and the right incomplete inner liner tube 2 into the old pipe. Use the pressing plate 11, trapezoidal extrusion block 10 and trapezoidal moving block 8 to make the two moving plates 5 move away from each other. Then insert the fixing plate 3 on the left incomplete inner liner tube 1 into the fixing groove and align the limiting groove with the limiting plate 6. Then release the pressing plate 11. Under the action of the return spring 12, the trapezoidal extrusion block 10 is reset. Under the elastic action of the extrusion spring 7, the limiting plate 6 is fixed to the fixing plate 3.

[0043] S2. After it is fixed, press the circular plate 28. The circular plate 28 moves the movable plate 23 through the pressure rod 27. The movement of the movable plate 23 will drive the fixed column 26 to move, thereby causing the fixed column 26 to be removed from the fixing hole. At this time, move the annular adjustment plate 21. The movement of the annular adjustment plate 21 drives the annular sealing plate 19 to move through the annular slider 18. When it moves to the designated position, release the circular plate 28. Under the action of the compression spring 25, the movable plate 23 is reset, thereby fixing the annular slider 18 and thus initially sealing the left incomplete inner liner tube 1 and the right incomplete inner liner tube 2.

[0044] S3. After the initial sealing is completed, the expansion airbag 20 is inflated through the air inlet to make it expand, and under the action of the annular baffle 22, the left incomplete inner liner tube 1 and the right incomplete inner liner tube 2 are sealed.

[0045] S4. Then, inject waterproof sealant through grouting port 16 to completely seal the left incomplete inner lining pipe 1 and the right incomplete inner lining pipe 2 with the original pipe.

[0046] Working principle of this invention:

[0047] In use, first place the left incomplete inner liner 1 and the right incomplete inner liner 2 into the old pipe. After placement, press the pressing plate 11. The movement of the pressing plate 11 moves the moving column 9, which in turn moves the trapezoidal extrusion block 10. When the inclined surface of the trapezoidal extrusion block 10 contacts the two trapezoidal moving blocks 8, the continued movement of the trapezoidal extrusion block 10 will extrude the two trapezoidal moving blocks 8. Under the action of the limiting rod 4, the two moving plates 5 move away from each other, which in turn causes the two limiting plates 6 to move away from each other. At this point... Next, insert the fixing plate 3 on the left incomplete inner liner tube 1 into the fixing groove, and align the limiting groove with the limiting plate 6. After alignment, release the pressing plate 11. Under the action of the return spring 12, the pressing plate 11 will reset. The resetting of the pressing plate 11 will cause the trapezoidal extrusion block 10 to reset. The resetting of the trapezoidal extrusion block 10 will no longer extrude the trapezoidal moving block 8. At this time, the two moving plates 5 will approach each other under the elastic action of the four extrusion springs 7, thereby fixing the limiting plate 6 to the fixing plate 3. After it is fixed, press the circular plate 28 again. Plate 28 moves movable plate 23 via pressure rod 27. The movement of movable plate 23 causes fixed column 26 to move, thus releasing the fixation. Then, the annular adjusting plate 21 is moved, causing annular slider 18 to move. Annular slider 18 then moves annular sealing plate 19. When it reaches the designated position, plate 28 is released. Under the action of compression spring 25, movable plate 23 returns to its original position. The return of movable plate 23 resets fixed column 26, thus fixing annular slider 18, thereby allowing the left... The incomplete inner liner tube 1 and the right incomplete inner liner tube 2 are initially sealed. At this time, the expansion airbag 20 is inflated through the air inlet to make it expand. Under the action of the annular baffle 22, the left incomplete inner liner tube 1 and the right incomplete inner liner tube 2 are sealed. Then, the waterproof sealant is injected through the grouting port 16, so that the left incomplete inner liner tube 1 and the right incomplete inner liner tube 2 are completely sealed with the original pipe. Finally, the stainless steel strip 13 is used for reinforcement. Thus, the reinforcement and repair can be carried out without hammering, which is convenient for use.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
