The PE pipe comprises a PE pipe 1, a first cladding piece 2, a second cladding piece 3, a raw rubber belt 4, a heat shrinkage pipe 5, a PE pipe rush-repair section 6, a refrigeration rod 7, a near water end 8 and a far water end 9.
Detailed Description
The following is a further detailed description of the embodiments:
as shown in fig. 1 and 2, a rapid repair method for PE pipe rupture includes the steps of:
s1, cutting off two ends of a broken part of a PE pipe 1 to obtain a near water end 8 and a far water end 9 with opposite pipe orifices;
s2, freezing and plugging are carried out on the near water end 8 on the PE pipe 1 through a refrigeration technology;
s3, cleaning the outer side surfaces of the near water end 8 and the far water end 9 of the PE pipe 1, and sleeving the heat shrinkage pipe 5 on the PE pipe 1 from the far water end 9;
s4, overlapping the near water end 8 and the far water end 9 by using a pipe supplementing element;
s5, winding a raw adhesive tape 4 on the outer side of the pipe supplementing element, and coating the pipe supplementing element and a part of PE pipe 1 positioned on the outer side of the end part of the pipe supplementing element;
s6, sliding the heat shrinkage tube 5 to enable the heat shrinkage tube 5 to fully cover the tube supplementing element, and then heating the heat shrinkage tube 5 to enable the heat shrinkage tube 5 to be tightly contracted on the PE tube 1;
and S7, using the PE pipe rush-repair joint 6 to squeeze and lock the pipe supplementing part on the PE pipe 1.
In this embodiment, the proximal end 8 refers to the end near the valve closing end after the broken portion of the PE pipe 1 is cut, and the remaining end is the distal end 9. Before executing step S1, close a valve that is closest to PE pipe 1 pipeline rupture department, close the valve, can cut off the rivers in the PE pipe 1, avoid salvaging the water source waste that makes, can also avoid flowing rivers to influence salvaging work simultaneously. And in this embodiment, the pipe is not used to connect the near water end 8 and the far water end 9, because, in order to ensure the sealing effect between the pipe and the near water end 8 and the far water end 9, the inner diameter of the pipe and the outer diameter of the PE pipe 1 should be equal to each other in an infinite way, but this faces a problem in that, when the pipe is sleeved, since the length of the pipe needs to be greater than the length of the cut PE pipe 1 and the inner diameter of the pipe is equal to the outer diameter of the PE pipe 1, when the pipe is installed, if the diameter of the PE pipe 1 is greater, the pipe is not easy to bend, and the PE pipe 1 itself is bent, and when the surface is uneven, it is very difficult for the near pipe to be sleeved on the near water end 8 and the far water end 9.
In step S2, the manner of blocking the near water end 8 by freezing is that the refrigeration rod 7 is blocked or liquid nitrogen is blocked, in this embodiment, the refrigeration rod may be a refrigeration pipe, when the refrigeration rod 7 is used for blocking, the refrigeration rod 7 is placed at the lower part of the near water end 8PE pipe 1 and contacts with the PE pipe 1, because the breaking position of the PE pipe 1 is quite distant from the valve, after the valve is closed, the water flow in the PE pipe 1 still needs to flow for quite a long time, but in order to avoid long-time water interruption in the rush repair process, the life of residents is not influenced, therefore, the PE pipe 1 can be rush repaired by freezing the water flowing out of the near water end 8, the temperature of the near water end 8 of the PE pipe 1 is reduced by the refrigeration rod 7, the water flow in the PE pipe 1 is in a frozen state, an ice wall is formed, and the height of the ice wall is increased until the water flow in the PE pipe 1 is gathered.
When using the liquid nitrogen shutoff, need set up the U type pipe of laminating with near water end 8 in the outside of PE pipe 1, then pour into U type intraductal with liquid nitrogen, because the temperature of liquid nitrogen is very low, if directly act on PE pipe 1, very easily cause low temperature damage to PE pipe 1 pipe, consequently through the mode of cold transmission, can freeze the rivers in the PE pipe 1, still can not cause the damage to PE pipe 1.
In step S6, the length of the heat shrink tubing 5 fully encapsulates the patch element and the raw tape 4.
The pipe supplementing element comprises a first coating part 2 and a second coating part 3, wherein the two ends of the first coating part 2 and the second coating part 3 are respectively overlapped on a near water end 8 and a far water end 9, the radian of the first coating part 2 is larger than that of the second coating part 3, the arc length of the first coating part 2 is longer, the coating area is large, the end part of the first coating part 3 and the end part of the second coating part 3 are at least partially overlapped when the pipe supplementing element is installed, the end part of the first coating part 2 is positioned on the inner side of the end part of the second coating part 3, the far water end 9 of the near water end 8 is communicated through the overlapping of the end parts of the first coating part 2 and the second coating part 3 to play the role of a connecting pipeline, after the installation is finished, under the action of water pressure, as the contact area between the first cladding piece 2 and the water flowing in the first cladding piece is large, the pressure of the water is applied, the two ends of the first cladding piece 2 have a trend of expanding outwards, namely, the two ends of the first cladding piece 2 are propped against the overlapped part of the first cladding piece 2 and the second cladding piece 3, so that the automatic locking of the first cladding piece 2 and the second cladding piece can be realized, the contact sealing effect between the first cladding piece and the second cladding piece is improved, and the installation mode is that the second cladding piece 3 is installed on the first cladding piece, because the arc length of the first cladding piece 2 is longer, the fixation is firmer, the gravity of the water is borne, and the influence of the gravity of the water on the connection stability is reduced.
In step S7, when the PE pipe repair section 6 performs extrusion locking on the pipe supplementing portion, at least the end portion of the pipe supplementing element is extruded on the PE pipe 1, and the end portion of the pipe supplementing element is extruded and sealed, so that the water leakage preventing effect is further improved.
Before step S7, the method further includes winding the surface of the shrink heat shrinkage tube 5 with the raw rubber belt 4, tightly attaching the shrink heat shrinkage tube 5 to the pipe supplementing element after the shrink heat shrinkage tube 5 is shrunk, and extruding and sealing the end parts of the pipe supplementing element on the near water end 8 and the far water end 9 to achieve sealing effect, and winding the raw rubber belt 4 on the outer side surface of the pipe supplementing element can further improve sealing and water leakage preventing effects.
After step S7, if the broken PE pipe 1 is buried in soil, it is necessary to fill the repair distribution with soil after the completion of the rush repair.
The heat shrinkage tube 5 is a PET heat shrinkage tube 5, the heat resistance, the electrical insulation property and the mechanical property of the PET heat shrinkage tube 5 (the PET heat shrinkage tube 5) are greatly higher than those of pvc heat shrinkage tubes, and more importantly, the PET heat shrinkage tubes have no toxicity, are easy to recycle, do not have toxic influence on human bodies and the environment, and meet the environmental protection requirement.
