Problems solved by technology

[0003] Because the existing repairing method and expansion joint device of urban pipe gallery leakage expansion joints only adopt the method of collar, the collar is sleeved on the place where the pipeline leaks or cracks, and the collar is locked by external force, so that the expansion joint shrink, and prevent the liquid from flowing out through the collar, but the inventor found that this method can only deal with it for a while, and cannot effectively repair the gap. Instead, the gap will expand due to the passage of time. Therefore, this method and device cannot long-term use

Embodiment 1

[0044] In a typical embodiment of the present invention, such as figure 1 and figure 2 As shown, a device for repairing expansion joints of urban pipe gallery leakage, including a strap, which can be arranged around the pipe; , the strap can be pulled relative to the movable end; the fixer 1, the fixer 1 is connected with the strap fixing part, the fixer 1 is provided with a groove for setting the bonding material in the groove, so as to apply the bonding material Overlay on the place where the pipeline needs to be repaired. Further, the fixer 1 includes a first end connected to the fixed end and a second end connected to the movable end, so that when the movable end is close to the fixed end, the first end and the second end also close to each other.

[0045] Wherein, the groove includes a first card slot 105 provided at the first end and a second card slot 106 provided at the second end. When the second end is in use, the fixed end of the strap holder 2 is below. The fir...

Embodiment 2

[0053] A method for repairing leakage and expansion joints of urban utility corridors, using the device for repairing leakage and expansion joints of urban utility corridors described in Embodiment 1, comprising the following contents:

[0054] Apply the glue evenly on the outside of the water storage tank 104 of the fixer 1, then fix the fixer 1 with screw holes 201 on the lower end of the expansion joint of the pipeline, and then fix the fixer 1 with the fixing screws 202 on the pipe The upper end of the expansion joint, at this moment, the staff just can pass the strap 3 into the strap inlet 203 on the strap holder 2, and extend from the strap outlet 204, then, the staff passes the one-way wheel 207 to Adjust the tension of the strap 3 so that the strap 3 is at 34-69σb, the staff will place the BB glue stick in the recess, and start the heating plate 102 through the switch key 101 to heat for 10-30min, and then the staff will turn off the heating plate 102 Then adjust the b...

Embodiment 3

[0056] A method for repairing leakage and expansion joints of urban utility corridors, using the device for repairing leakage and expansion joints of urban utility corridors described in Embodiment 1, comprising the following contents:

[0057] Apply the glue evenly on the outside of the water storage tank 104 of the fixer 1, then fix the fixer 1 with screw holes 201 on the lower end of the expansion joint of the pipeline, and then fix the fixer 1 with the fixing screws 202 on the pipe The upper end of the expansion joint plays the role of initially fixing the fixed end and the movable end of the strap through the glue. At this time, the staff can pass the strap 3 into the strap inlet 203 on the strap holder 2, and Extending from the strap outlet 204, then the staff adjusts the tension of the strap 3 through the one-way wheel 207, so that the strap 3 is at 53σb, the worker places the BB glue stick in the heating plate 102, and passes the switch Key 101 starts the heating plate...

Abstract

The invention discloses a repairing device and a repairing method of an urban pipeline gallery leakage expansion joint. The repairing device solves the problems that operation of repair a pipeline bya lantern ring is complicated and the service life is short in the prior art, and has the beneficial effects that the expansion joint of the pipeline can be repaired effectively, and repairing tools can be used for a long time. According to the following technical scheme, the repairing device of the urban pipeline gallery leakage expansion joint comprises a tieback, a tieback fixing part, and a fixator, wherein the tieback can be arranged around the pipeline; the tieback fixing part comprises a fixing end arranged at one end of the tieback and a movable end that the tieback can penetrate through, and the tieback can be pulled relative to the movable end; and the fixator is fixedly connected with the tieback fixing part and is provided with a groove for arranging a binding material in the groove to apply the binding material to the position needing to be repaired of the pipeline.

Description

technical field [0001] The invention relates to the technical field of pipeline repair, in particular to a repair device and repair method for leakage expansion joints of urban pipe corridors. Background technique [0002] Pipeline repair refers to the use of various techniques for damaged and leaking pipelines to restore their normal functions. The repair includes two technologies: external anti-corrosion layer repair and internal repair. Conduct external anti-corrosion layer detection and evaluation, and then repair according to the evaluation report. [0003] Because the existing repairing method and expansion joint device of urban pipe gallery leakage expansion joints only adopt the method of collar, the collar is sleeved on the place where the pipeline leaks or cracks, and the collar is locked by external force, so that the expansion joint shrink, and prevent the liquid from flowing out through the collar, but the inventor found that this method can only deal with it f...
