Detailed Description
The following is further detailed by way of specific embodiments:
as shown in fig. 1 and 2, a rapid repair method for PE pipe rupture includes the following steps:
s1, cutting off two ends of the broken part of the PE pipe 1 to obtain a near water end 8 and a far water end 9 opposite to the pipe openings;
s2, freezing and plugging 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 shrinkable 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 the raw adhesive tape 4 on the outer side of the pipe repairing element, and coating the pipe repairing element and the PE pipe 1 positioned on the outer side of the end part of the pipe repairing element;
s6, sliding the heat shrinkable tube 5 to enable the heat shrinkable tube 5 to fully coat the tube repairing element, and then heating the heat shrinkable tube 5 to enable the heat shrinkable tube 5 to be shrunk on the PE tube 1;
and S7, pressing and locking the repair pipe part on the PE pipe 1 by using the PE pipe repair joint 6.
In this embodiment, the proximal end 8 refers to the end close to the closed valve after the PE pipe 1 is broken, and the remaining end is the distal end 9. Before step S1 is executed, close the nearest valve apart from PE pipe 1 pipeline rupture department, close the valve, can cut the rivers in PE pipe 1, avoid salvageing the water source that makes extravagant, can also avoid flowing rivers to cause the influence to salvage work simultaneously. And how do not adopt the mode of the pipe to communicate near water end 8 and far water end 9 in this embodiment, the reason is, in order to guarantee the sealed effect of pipe and near water end 8 and far water end 9, so the internal diameter of pipe and the external diameter of PE pipe 1 should be infinitely nearly equal for the ideality, but just face a problem like this, when cup jointing the pipe, because the length of pipe needs to be greater than by the length of intercepting PE pipe 1 and the internal diameter of pipe is equal with the external diameter of PE pipe 1, so when the installation, if the diameter of PE pipe 1 is great, it is inflexible, and PE pipe 1 self has the crooked condition, and when the unsmooth condition in surface, so the nearly pipe cup joints on near water end 8 and far water end 9 very difficultly.
The freezing and plugging mode of the near water end 8 in the step S2 is a refrigeration stick 7 plugging or a liquid nitrogen plugging, in this embodiment, the refrigeration stick may be a refrigeration pipe, wherein when the refrigeration stick 7 is used for plugging, the refrigeration stick 7 is placed at the lower part of the near water end 8PE pipe 1 and contacts with the PE pipe 1, because the rupture position of the PE pipe 1 is far away from the valve in a large probability, after the valve is closed, the water flow in the PE pipe 1 can flow for a long time to cut off, but in order to avoid long-time water cut-off in the emergency repair process, the life of residents is affected, therefore, the PE pipe 1 is plugged by freezing the water flowing out of the near water end 8, i.e. the PE pipe 1 can be repaired, the refrigeration stick 7 reduces the temperature of the near water end 8 of the PE pipe 1, so that the water flow in the PE pipe 1 is in a frozen state to form an ice wall, and the height of the ice wall is increased by continuously converging the water flow, until the water flow in the PE pipe 1 is sealed.
When using the liquid nitrogen shutoff, need set up the U type pipe of 8 laminatings of near water end in the outside of PE pipe 1, then pour into the U type intraductal with the liquid nitrogen, because the temperature of liquid nitrogen is very low, if direct action is on PE pipe 1, very easily cause the low temperature to damage PE pipe 1 pipe, consequently through the mode of cold transmission, can be to the rivers in PE pipe 1 when freezing, still can not cause the damage to PE pipe 1.
In step S6, the length of the heat shrinkable tube 5 entirely covers the patch member and the raw tape 4.
The pipe supplementing element comprises a first coating member 2 and a second coating member 3, wherein two ends of the first coating member 2 and the second coating member 3 are respectively lapped on a near water end 8 and a far water end 9, the radian of the first coating member 2 is larger than that of the second coating member 3, the arc length of the first coating member 2 is longer, the coating area is large, specifically as shown in the figure, the end part of the first coating member 3 is at least partially overlapped with the end part of the second coating member 3 during installation, the end part of the first coating member 2 is positioned on the inner side of the end part of the second coating member 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 member 2 and the second coating member 3, the function of connecting a pipeline is achieved, after the installation is completed, under the action of water pressure, the contact area of the first coating member 2 and water flowing inside the first coating member is large, so that the two ends of the first coating member 2 have the tendency of outward expansion under the water pressure, the both ends that can make first cladding piece 2 support tightly on the part that first cladding piece 2 and second cladding piece 3 overlap promptly, can realize the automatic locking of the two, promote the sealed effect of contact between the two, preferred mounting means is that second cladding piece 3 is installed last, because the arc length of first cladding piece 2 is longer, fixed more firm, makes it undertake the gravity of water, reduces the influence of water gravity to connecting the steadiness.
In step S7, when the PE pipe repair joint 6 presses and locks the pipe repair part, at least the end of the pipe repair element is pressed on the PE pipe 1, and the end of the pipe repair element is pressed and sealed, thereby further improving the water leakage prevention effect.
Before step S7, winding the surface of the shrunk heat shrinkable tube 5 with the raw adhesive tape 4, after the heat shrinkable tube 5 is shrunk, the heat shrinkable tube can be tightly attached to the tube repairing element, and the end of the tube repairing element is sealed on the near water end 8 and the far water end 9 by pressing, so as to achieve the sealing effect, and the winding the raw adhesive tape 4 on the outer side surface can further improve the sealing and water leakage prevention effects.
After step S7, if the broken PE pipe 1 is buried in the soil, it is necessary to fill the repair distribution with the soil after the completion of the emergency repair.
The heat shrinkable tube 5 is a PET heat shrinkable tube 5, the heat resistance, the electrical insulation performance and the mechanical properties of the PET heat shrinkable tube 5 (the polyester heat shrinkable tube 5) greatly exceed those of a pvc heat shrinkable sleeve, and more importantly, the PET heat shrinkable sleeve is non-toxic and easy to recover, does not generate toxic influence on human bodies and the environment, and meets the requirement of environmental protection.
