Description of the invention: [Technical field to which the invention pertains] ~ The present invention relates to a method for defending a pipeline, and more particularly to a method of freezing construction for freezing a liquid in a road to facilitate construction. [Prior Art] In general, households often live in food, clothing, housing, transportation, education, or hospitals, firefighting, science parks, water companies, etc.: Water and electricity are inseparable. When you encounter a power failure due to a water stop, you can't help but complain about the construction and stop the water and power, so that ^ will cause much trouble to users! This is a problem that people often complain about. In the traditional maintenance of public pipelines, the water source is usually turned off to allow users in this area to suspend water until the public pipeline is repaired before it is opened. The water source restores public water. Therefore, the number of households affected by the maintenance of public pipelines is very large. How to reduce the impact of maintenance is the problem to be discussed by the industrial or contractor. θ Α and Figure 1 show the construction method of the pipeline cold construction. Please refer to the ®-A and Figure-B's technology. The technology is to make a closed space in the pipeline. Then, the liquid nitrogen in the liquid nitrogen bottle is driven into the closed space to make the area. The liquid in the segments condenses into a solid. The advantage of this method is that the liquid in the pipe section can be quickly solidified into a solid and can be applied in a short time. The disadvantage is that the use of liquid nitrogen pollutes the environment and there is a certain risk in use. For the construction of time 201124688, the liquid gas makes the liquid solidify for a limited time and is suitable for long time construction. How to control the solidification time safely and effectively is the problem that people in this field need to face and solve, so there is a need for a cold-beam construction method to solve the problems caused by conventional technology. . SUMMARY OF THE INVENTION In view of the lack of the above-mentioned Xilai riding, the present invention provides a kind of pipeline cold Kang Shi = method 'does not use (4) to change the use of heat exchangers for environmental pollution and valuable liquid gas, not only can reduce the prior The king's preparation time plate safety (four) consider the time of mx control liquid solidification to match the pipeline construction. In the present invention, the present invention provides a method for cold-tube construction of a pipeline, which comprises the steps of: providing - a pipeline, which provides - liquid passage; providing - directing, the system-end has - cold (four) , which is coupled to the pipeline section of the pipeline; a heat exchanger that is connected to the other end of the conduit; and activating the heat exchanger to condense the liquid of the section solid. In another embodiment, the present invention provides a pipeline cold bead construction; the method includes the following steps: providing a pipeline, which provides a liquid yellow through a helium supply-guide tube, the system having a - condensing f, which is sharper than the pipe section of the official road; providing - an insulating material that coats the condensing pipe on the (four) road section; providing a heat exchanger connected to the guiding, The other end; the heat exchange H' is activated to cause the liquid of the f-way section to condense i solid; the pressure gauge is provided to measure whether the pressure behind the f-section is ^Okg/cm2; and in the pipeline section Pipeline construction at the rear. 201124688 [Embodiment] In order to enable the reviewing committee to understand and understand the characteristics, purposes, and further understanding of the creation, the relevant details of the device and the concept of the device of the present invention are explained. The inspection committee can understand the characteristics of this creation, and the detailed explanations are as follows: 1. First, refer to the figure shown in Figure 2, which is the process of the cold-wired pipe of the invention. This process 2 first provides a tube in step 21 which provides - liquid passage. Next, step 22 is provided to provide a guide f' having a system-end having a condensation f' which is coupled to one of the tube sections of the line. Subsequent step 2 3 provides a heat exchanger that is coupled to the other end of the pilot. Finally, step 24 is initiated to activate the heat exchanger to condense the liquid in the line section to a solid. Please refer to Figure 3A and Figure 3 for a schematic diagram of an embodiment of the pipeline freezing construction method of the present invention. The line section is connected to the condensing pipe 33 on the pipe raft through which the liquid flows, and the condensing f 33 is connected to the pilot pipe and is engaged with the hot parent for H 34. In the present embodiment, the liquid is water, and the heat exchanger is a refrigeration compressor, and the condensation tube may be selected from steel, aluminum or an alloy thereof, but is not limited thereto. When the heat exchanger 34 is activated, the condensing pipe 33 gradually forms a layer of frost, and the temperature of the liquid 35 in the pipe section covered by the condensing f 33 gradually decreases until it condenses into a solid enthalpy. The liquid 35 inside is blocked by the solids 36 in the section of the pipeline 31 and is in a non-circulating state, after which the constructor can carry out construction behind the pipeline section until the heat exchanger is turned off after the construction is completed. 34. The solids in the pipeline section gradually melt into a liquid, after which the pipeline 31 resumes the state of circulation 201124688. The figure is shown in Fig. 4. This figure is a schematic flow chart of another embodiment of the cold rolling construction of the pipeline of the present invention. The process 4 first provides a route 1 to provide a liquid pass. Next, step 42 is provided to provide a conductive connection: the system has a condensation tube, which is coupled to one of the pipelines of the pipeline, and then a step of providing a thermal insulation material, which is coated with the thermal insulation material. , condensation tube. Step 44 provides a heat exchanger that is coupled to the other end of the pair. Step 45 starts the heat exchanger to make the pipeline section! body. Step 46 provides a pressure gauge that measures whether the line I force is 0 kg/cm2. If the pressure is 0 kg/cm2, then the line is down/y, and if the pressure is greater than 〇kg/cm2, return to step 45. Finally, step 47 is performed to perform a plumbing procedure behind the pipeline section.乂 Refer to Figure 5A and Figure 5B, which is the pipeline cooling of the present invention; the east construction method is another – the actual indication (4). The condensation f 33 is more 'melon material 37' for the purpose of isolating the higher ambient temperature to maintain the condensate tube 33 to condense the liquid % of the line 31 section into a solid 36' with optimum efficiency to accelerate the solidification time of the liquid 35. . It can be observed that the pressure gauge 38 can know the solidification of the liquid 35. When the pressure gauge 38 is shown as /c solid 36, it can block the flowing liquid in front, and the constructor can start in the pipeline section. Pipeline construction at the rear. Please refer to FIG. 6A and FIG. 6B, which are schematic diagrams of another embodiment of the pipeline cold-breaking construction method of the present invention.
