Description

Technical Field

[0001] This application relates to the field of thermal pipeline construction technology, specifically to a construction method for a thermal system and a thermal system. Background Technology

[0002] Currently, leaks in heating pipelines are often only discovered and repaired when significant amounts of water have leaked. However, this significant leakage wastes water resources and disrupts the normal operation of the pipelines. One related technology utilizes a distributed fiber optic temperature measurement system to monitor the temperature of heating pipelines. Typically, during construction of each section, temperature-sensing optical fibers of matching length are placed in separate trenches. The ends of these fibers are then fused together to form a connected network, enabling temperature measurement.

[0003] However, the temperature-sensing optical fiber constructed in the above manner has a large number of fusion splices, which can cause the light inside the temperature-sensing optical fiber to change during transmission, resulting in inaccurate measurements.

[0004] Therefore, there is an urgent need to propose a solution to address the above problems. Summary of the Invention

Obviously, the described embodiments are only some, not all, of the embodiments of this application. Other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are all within the protection scope of this application.

Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0025] Furthermore, in this application, directional terms such as "upper," "lower," "inner," and "outer" are defined relative to the indicated placement of the components in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the placement of the components in the accompanying drawings.

[0026] To facilitate understanding of the technical solution of this application, the technical issues involved in this application will be explained first below.

[0027] In related technologies, distributed optical fiber temperature measurement systems are used to monitor the temperature of thermal pipelines. Typically, during construction of each section, temperature-sensing optical fibers of matching length are placed in separate trenches. The ends of these fibers are then fused together to form a connected temperature-sensing fiber, enabling temperature measurement. However, the aforementioned technologies result in temperature-sensing optical fibers with varying melting points, leading to light distortion during transmission and resulting in inaccurate measurements.

[0028] To address the aforementioned technical problems, this application proposes a construction method for a thermal system to reduce the melting point of the temperature-sensing optical fiber, reduce light distortion within the fiber, and improve the monitoring quality of the distributed temperature measurement system for the temperature and leak points of the thermal pipeline.

[0029] Figure 1 A schematic flowchart illustrating the construction method of the thermal system provided in this application embodiment.

[0030] This application provides a construction method for a thermal system, which includes a leak detection system and thermal pipes. The leak detection system includes a temperature-sensing optical fiber, and the thermal pipes are installed at a pre-defined location, such as... Figure 1 As shown, the construction method of the heating system includes steps S100 to S800, as detailed below: Step S100: Determine the target construction method based on the environmental information of the preset line.

[0031] In this step, the environmental information for the pre-set route includes environments suitable for trench construction and environments unsuitable for trench construction. Environments suitable for trench construction will use trench construction as the target construction method, which involves digging trenches on the surface and then laying heating pipes, etc., within the trenches. Environments unsuitable for trench construction will use pipe jacking construction as the target construction method, which involves using a pipe jacking machine to install pipes underground and then laying heating pipes, etc., within the pipes.

[0032] The preset route is a planned route for laying heating pipes. Specifically, the embodiments of this application are a construction method for laying heating pipes along the preset route, in order to reduce the melting point of the temperature-sensing optical fiber during the laying of the heating pipes and improve the ability of the temperature-sensing optical fiber to detect the temperature and leakage points of the heating pipes.

[0033] Specifically, based on environmental information, it can be determined whether it is suitable to excavate trenches for construction along the preset route. If it is suitable to excavate trenches, trench construction will be given priority, as it can reduce construction costs and complexity.

[0034] For example, environments unsuitable for trench construction include rivers or major transportation hubs. For instance, when laying heating pipelines across a river, it's inconvenient to dig trenches beneath the river; therefore, if the environmental information for the predetermined route includes rivers, the target construction method is pipe jacking. Similarly, when laying heating pipelines on major urban roads with high traffic volume, trench construction would affect traffic flow on the main roads, leading to traffic congestion; therefore, if the environmental information for the predetermined route includes major transportation hubs, the target construction method is pipe jacking.

[0035] Step S200: If the target construction method is trench construction, determine whether the preset route includes intersections.

[0036] In this step, if the pre-designed route includes intersections, the traffic flow at the intersections needs to be considered during construction to determine if the construction will significantly impact traffic conditions. Therefore, there may be situations where construction does not proceed simultaneously with the intersection and the roads on either side of it. To reduce the number of splice points for the temperature-sensing fiber optic cables, it is necessary to determine whether to reserve fiber optic cables within the roads on either side based on the construction sequence of the intersection and the roads on either side, thereby reducing the number of splice points for segmented fiber optic cable installation.

[0037] Figure 2 A construction diagram of a thermal system including an intersection, provided for an embodiment of this application.

[0038] For example, combined Figure 2 As shown in Figure (a), the preset route 01 in the figure includes intersection 09. Intersection 09 represents a complete intersection, while intersection 12 represents the part of the trench that needs to be dug on the complete intersection.

[0039] Step S300: In the case of intersections, determine the construction sequence of the intersections and other road segments on the preset route; the road segments are connected through the intersections.

[0040] Optionally, the preset route includes an intersection, a first road segment, and a second road segment. Other road segments include the first road segment and the second road segment, which are connected by the intersection. The ditch corresponding to the first road segment is the first ditch, the ditch corresponding to the second road segment is the second ditch, and the ditch corresponding to the intersection is the third ditch. The construction sequence includes a first construction sequence, a second construction sequence, and a third construction sequence. The first construction sequence includes: the first batch of trenches to be excavated are the first trench and the second trench; the first batch of trenches to be backfilled are either the first trench or the second trench; the second batch of trenches to be excavated is the third trench; the second batch of trenches to be backfilled is the third trench; and all trenches except those to be backfilled in the first batch. The second construction sequence includes: the first batch of trenches to be excavated are the first trench and the second trench; the first batch of trenches to be backfilled are the first trench and the second trench; the second batch of trenches to be excavated is the third trench; and the second batch of trenches to be backfilled is the third trench. The third construction sequence includes: the first batch of trenches to be excavated are the first trench, the second trench, and the third trench; the first batch of trenches to be backfilled are the first trench, the second trench, and the third trench.

[0041] In this embodiment, the trenches to be excavated in the first batch, the trenches to be backfilled in the first batch, the trenches to be excavated in the second batch, and the trenches to be backfilled in the second batch are determined according to the construction sequence. This allows the installation length of the temperature-sensing optical fiber in each trench to be determined according to the construction sequence, thereby reducing the number of splice points of the temperature-sensing optical fiber and improving the accuracy of the temperature-sensing optical fiber in detecting temperature and leakage points.

[0042] For example, combined Figure 2 As shown in (b), the pre-designed route includes intersection 12 (09), first section 10, and second section 11. The ditch corresponding to first section 10 is first ditch 13, the ditch corresponding to second section 11 is second ditch 14, and the ditch corresponding to intersection 12 is third ditch 15. The first construction sequence corresponds to... Figure 2 (c) and (d). The second construction sequence corresponds to Figure 2 In (e) and (f). The third construction sequence corresponds to Figure 2 (g). Among them, intersection 12 also indicates the location where the corresponding trench needs to be dug on the complete intersection 09.

[0043] Specifically, in combination Figure 2As shown in (c) and (d), the first construction sequence is to first dig the trenches corresponding to the road sections on both sides of the intersection (first trench 13 and second trench 14), then backfill the trench corresponding to the road section on either side of the intersection (first trench 13), then dig the trench corresponding to the intersection (third trench 15), and backfill the trench corresponding to the road section on the side that has not yet been backfilled (second trench 14) and the trench corresponding to the intersection (third trench 15). Under the first construction sequence, it is possible to first install reserved optical fibers in the trenches that need to be backfilled in the first batch, and then after digging the trench at the intersection, directly thread the reserved optical fibers into the trenches that need to be backfilled in the second batch (i.e., the intersection and the road section on the side that has not yet been backfilled), thereby reducing the melting points caused by splicing the temperature measuring optical fibers at both ends of the intersection.

[0044] Specifically, in combination Figure 2 As shown in (e) and (f), the second construction sequence is to first excavate the trenches corresponding to the road sections on both sides of the intersection (first trench 13 and second trench 14), then backfill the trenches corresponding to the road sections on both sides of the intersection (first trench 13 and second trench 14), and then excavate the trench corresponding to the intersection (third trench 15) and backfill it. Under the second construction sequence, it is possible to first install the reserved temperature-measuring optical fiber in any trench that needs to be backfilled in the first batch, and then after excavating the trench at the intersection, directly thread the reserved temperature-measuring optical fiber into the trench that needs to be backfilled in the second batch (i.e., the intersection and the road section on the side that has not yet been backfilled), and then fused the trenches at both ends of the intersection, thereby reducing the melting points caused by fusion splicing the temperature-measuring optical fiber at both ends of the intersection.

[0045] Specifically, in combination Figure 2 As shown in section (g), the third construction sequence involves simultaneously constructing the ditches corresponding to the road sections on both sides of the intersection and the ditches corresponding to the intersection itself (first ditch 13, second ditch 14, and third ditch 15), followed by backfilling the ditches corresponding to the road sections on both sides of the intersection and the ditches corresponding to the intersection itself. Under this third construction sequence, the temperature-sensing optical fiber can be directly laid to the ditches corresponding to the road sections on both sides of the intersection and the ditches corresponding to the intersection, thereby reducing the melting points caused by splicing the temperature-sensing optical fiber at both ends of the intersection.

[0046] Figure 3 The first and second road segments provided in this application embodiment are schematic diagrams of road segments on both sides of an intersection.

[0047] It should be understood that the first road segment and the second road segment provided in the embodiments of this application can be road segments set on opposite sides of an intersection (in combination with...). Figure 2 The first road segment 10 and the second road segment 11 shown in (b) can also be road segments on both sides of an intersection (i.e., the preset route is a route with a corner, combined with...). Figure 3(As shown in the first road segment 10 and the second road segment 11), this application does not limit this.

[0048] Step S400: Excavate the target trench along the preset route according to the construction sequence; the target trench is the first batch of trenches to be excavated in the construction sequence.

[0049] Step S500: Based on the construction sequence and the length of the target trench, determine the target installation length of the temperature-sensing optical fiber in the reserved trench; the temperature-sensing optical fiber is used to measure the leakage point of the thermal pipeline; the target trench includes the reserved trench.

[0050] Optionally, the length of the first trench is a first length, the length of the second trench is a second length, and the length of the third trench is a third length; the reserved trench includes a first reserved trench or a second reserved trench; step S500 includes steps S501 to S503, as follows: Step S501: In the case of the first construction sequence, the trenches to be backfilled in the first batch are designated as the first reserved trenches; a temperature measuring fiber of the first target installation length is installed in the first reserved trench; the first target installation length is the sum of the first length and the third length; the target installation length includes the first target installation length.

[0051] In this step, when the construction sequence is the first construction sequence, by installing a temperature-measuring optical fiber of the first target installation length in the first reserved trench, the reserved optical fiber is set in the first batch of trenches that need to be backfilled. This makes it convenient to directly thread the reserved optical fiber into the second batch of trenches that need to be backfilled (i.e., the intersection and the side of the road that has not yet been backfilled) after the trench at the intersection is dug. This reduces the melting point caused by splicing the temperature-measuring optical fiber at both ends of the intersection.

[0052] It should be understood that if the initial installation length of the target fiber is greater than the initial length of the temperature-sensing fiber, multiple segments of the initial temperature-sensing fiber need to be spliced ​​together. The initial length of the temperature-sensing fiber is the standard length of the initial temperature-sensing fiber when it leaves the factory.

[0053] Step S502: When the construction sequence is the second construction sequence, the first trench or the second trench is used as the second reserved trench; a temperature-measuring optical fiber of the second target installation length is installed in the second reserved trench; the second target installation length is the sum of the length of the second reserved trench and the length of the third trench; in the target trench, a temperature-measuring optical fiber of the third target installation length is installed in the trenches other than the second reserved trench; the third target installation length is the length of the trenches other than the second reserved trench; the target installation length includes the second target installation length and the third target installation length.

[0054] In this step, when the construction sequence is the second construction sequence, by installing a second target installation length of temperature-sensing optical fiber in the second reserved trench, the reserved temperature-sensing optical fiber is first set in any trench that needs to be backfilled in the first batch. Then, after the trench at the intersection is dug, the reserved temperature-sensing optical fiber is directly threaded into the trench that needs to be backfilled in the second batch (i.e., the intersection and the side section that has not yet been backfilled), and the trenches at both ends of the intersection are fused together, thereby reducing the melting point caused by fusion splicing the temperature-sensing optical fiber at both ends of the intersection.

[0055] For example, the second reserved groove is either the first groove or the second groove. When the second reserved groove is the first groove, the second target installation length is the sum of the first length and the third length, and the third target installation length is the second length. When the second reserved groove is the second groove, the second target installation length is the sum of the second length and the third length, and the third target installation length is the first length.

[0056] It should be understood that when the installation length of the second target and / or the third target is greater than the initial length of the temperature-sensing fiber, multiple segments of the initial temperature-sensing fiber need to be spliced ​​together. The initial length of the temperature-sensing fiber is the standard length of the initial temperature-sensing fiber at the time of manufacture.

[0057] In step S503, when the construction sequence is the third construction sequence, temperature measuring optical fibers of the fourth target installation length are sequentially laid in the first trench, the second trench and the third trench; the fourth target installation length is the sum of the first length, the second length and the third length; the target installation length includes the fourth target installation length.

[0058] In this step, when the construction sequence is the third construction sequence, the fourth target installation length of the temperature measuring fiber is laid in the first trench, the second trench and the third trench in sequence. This allows the temperature measuring fiber to be directly laid to the trenches corresponding to the road sections on both sides of the intersection and the trenches corresponding to the intersection, thereby reducing the melting point caused by splicing the temperature measuring fiber at both ends of the intersection.

[0059] It should be understood that when the installation length of the fourth target is greater than the initial length of the temperature-sensing fiber, multiple segments of the initial temperature-sensing fiber need to be spliced ​​together. The initial length of the temperature-sensing fiber is the standard length of the initial temperature-sensing fiber when it leaves the factory.

[0060] In this embodiment, by setting different target installation lengths for different construction sequences, the melting point of the temperature-sensing fiber can be reduced, thereby improving the accuracy of temperature and leakage detection by the temperature-sensing fiber.

[0061] For example, the excavated first trench 10, second trench 11 and third trench 12 are as follows: Figure 2 As shown in (b).

[0062] It should be understood that, in combination Figure 3 As shown, if the road segments are adjacent to each other at an intersection, then the third length is... Figure 3 The length of the first intersection A is the sum of the length of the second intersection B. The length of the first intersection is half the width of the third ditch, and the length of the second intersection is half the length of the third ditch.

[0063] Step S600: Install the heating pipes in the target trench.

[0064] Optionally, step S600 includes steps S601 to S602, specifically including: Step S601: The heat pipe includes multiple sub-pipes. Each sub-pipe is welded to connect the sub-pipes to form a heat pipe.

[0065] Step S602: Insulate the heating pipes.

[0066] In this embodiment, each sub-pipe is welded together to form a thermal pipeline, thereby enabling the normal operation of the thermal system.

[0067] Specifically, when welding each sub-pipe, welding pits need to be dug at the connection points of each sub-pipe to facilitate welding of each sub-pipe and connect the sub-pipes to form a heat pipe.

[0068] Optionally, the thermal insulation treatment of the heat pipe includes, but is not limited to, providing an insulation layer on the outer wall of the heat pipe.

[0069] Specifically, in combination Figure 2 As shown, the heating pipe 05 includes a water supply pipe 03 and a return water pipe 04. The installation order of the water supply pipe 03 and the return water pipe 04 is not restricted during installation.

[0070] Step S700: Install the temperature-sensing optical fiber of the target installation length onto the thermal pipeline.

[0071] Optionally, the target trench includes multiple weld pits, and each weld pit corresponds to a connection point of a sub-pipe; step S700 includes the following step S701: Step S701: At the welding pit, use binding wire to fix the temperature measuring optical fiber and the heat pipe; the heat pipe includes a water supply pipe and a water return pipe, and the temperature measuring optical fiber includes a first temperature measuring optical fiber and a second temperature measuring optical fiber. The first temperature measuring optical fiber is located between the wall of the target trench and the outer wall of the water supply pipe, and the second temperature measuring optical fiber is located between the wall of the target trench and the outer wall of the water return pipe.

[0072] In this embodiment, temperature-measuring optical fibers are installed in the supply and return water pipes respectively to detect the temperature and leakage points of the supply and return water pipes.

[0073] Figure 4This is a schematic diagram showing the distance between the temperature-measuring optical fiber and the thermal pipeline provided in an embodiment of this application.

[0074] Optionally, combined Figure 4 As shown, the distance d between the outer wall of the temperature measuring fiber 06 and the outer wall of the heat pipe 04 is less than or equal to 20cm.

[0075] In this embodiment, by limiting the distance between the outer wall of the temperature-sensing optical fiber and the outer wall of the heat pipe, it is ensured that the temperature-sensing optical fiber can detect temperature changes around the heat pipe.

[0076] Optionally, before step S700, step S702 is also included, as follows: Step S702: Fabricate a temperature-sensing optical fiber of the target installation length. The temperature-sensing optical fiber is obtained by threading an optical cable through a silicon core tube.

[0077] In this embodiment, the temperature-measuring optical fiber is made using factory-made optical cable and silicon core tube. The silicon core tube is used as a protective tube for the optical cable to protect it and reduce the risk of damage to the optical cable from foreign objects during backfilling or from on-site construction machinery. It can also reduce the risk of optical cable breakage caused by land subsidence during long-term operation, extend the service life of the optical cable, and reduce the later maintenance costs of the system.

[0078] Optionally, after step S701, step S703 is also included, as follows: Step S703: Multiple water inlet holes are opened on the silicon core tube of the temperature measuring optical fiber; the water inlet holes correspond one-to-one with the connection points of the sub-pipes; the water inlet holes are round holes with a diameter of 4mm to 6mm.

[0079] In this embodiment, a water inlet is created on the silicon core tube so that, in the event of a leak in the heating pipe, the leaking water will enter the temperature-sensing optical fiber through the water inlet and come into contact with the optical cable. This affects the propagation of the optical signal within the cable, allowing for leak detection of the heating pipe based on abnormal changes in the optical signal, thus improving the accuracy of leak detection.

[0080] Specifically, because the temperature-sensing fiber is placed below the heating pipe, when the heating pipe leaks, the leaking water will flow to the temperature-sensing fiber and thus enter the heating pipe.

[0081] For example, since the probability of leakage points appearing at the welded joints of the heating pipe is relatively high, the water inlet can be set at the welded joint of the heating pipe, that is, at the weld pit, which is also the connection of the sub-pipe.

[0082] Optionally, after step S703 and before step S700, step S704 is also included: Step S705: Multiple water outlet holes are opened on the silicon core tube of the temperature measuring optical fiber; the water outlet holes correspond one-to-one with the water inlet holes.

[0083] In this embodiment, a water outlet is provided to facilitate the drainage of water flowing into the silicon core tube. This allows the water in the silicon core tube to be drained as quickly as possible once the heat pipe stops leaking, thus restoring normal temperature detection of the temperature-sensing optical fiber.

[0084] Step S800: Backfill the target trench.

[0085] The construction method of the thermal system provided in this application reduces the melting point of the temperature-sensing optical fiber by judging the construction method and whether it includes intersections or other related issues that may lead to splices in the temperature-sensing optical fiber. This reduces light distortion in the temperature-sensing optical fiber, improves the monitoring quality of the distributed temperature measurement system for the temperature and leakage points of the thermal pipeline, and extends the service life of the temperature-sensing optical fiber.

[0086] Optionally, after step S800, the method further includes: using an optical time domain reflectometer (OTDR) to detect the quality of the optical cable laying; detecting the presence of sheet piles; and removing the sheet piles if they are present.

[0087] Figure 5 This is a construction diagram of a heating system that does not include intersections, provided as an embodiment of this application.

[0088] For example, combined Figure 5 As shown in Figure (a), the preset route 01 in the figure is the route for installing the heating pipe in this embodiment of the application.

[0089] Optionally, after step S200, steps S201 to S205 are also included, as follows: Step S201: Excavate and install trench 02 according to the preset route, excluding intersections.

[0090] In this step, combined Figure 5 As shown in (b), an installation trench 02 is dug on the preset line 01.

[0091] Step S202: Lay the heating pipe 05 in the installation trench 02.

[0092] In this step, combined Figure 5 As shown in (c), a heating pipe 05 is laid in the installation trench 02. Specifically, the heating pipe 05 includes a water supply pipe 03 and a water return pipe 04.

[0093] Step S203: Lay the temperature measuring fiber optic cable 08 in the installation trench 02.

[0094] In this step, combined Figure 5As shown in (d), a temperature-sensing optical fiber 08 is laid in the installation trench 02. Specifically, the temperature-sensing optical fiber 08 includes a temperature-sensing optical fiber 06 for the water supply pipe and a temperature-sensing optical fiber 07 for the return water pipe.

[0095] Step S204: Fix the heating pipe 05 and the temperature measuring fiber optic cable 08.

[0096] Specifically, the distance between the outer wall of the heating pipe 05 and the outer wall of the temperature measuring optical fiber 08 is less than or equal to 20cm.

[0097] Step S205: Backfill the installation trench 02.

[0098] Optionally, after step S800, steps S900 to S1200 are also included, as follows: Step S900: Following the construction sequence, excavate the second batch of trenches to be excavated.

[0099] Specifically, steps S900 to S1200 are only required when the construction sequence is the first construction sequence or the second construction sequence.

[0100] Step S1000: Determine whether it is necessary to fusion splice the temperature measurement fiber.

[0101] Specifically, in the case of the first construction sequence, there is no need to fusion splice the temperature-sensing fiber. Instead, after excavating the second batch of trenches, the temperature-sensing fiber pre-installed in the first batch of trenches to be backfilled is extracted and deployed in the second batch of trenches, thus achieving the deployment of the temperature-sensing fiber in the first, second, and third trenches. For example, this means deploying the temperature-sensing fiber of the first target installation length in the first, second, and third trenches.

[0102] When the construction sequence is the second construction sequence, it is necessary to fusion splice the temperature-sensing optical fibers pre-installed in the first and second trenches, respectively. After excavating the second batch of trenches, the temperature-sensing optical fibers pre-installed in the first and second trenches are fusion spliced ​​to achieve the deployment of the temperature-sensing optical fibers in the first, second, and third trenches. For example, this means deploying temperature-sensing optical fibers of the second target installation length and the third target installation length in the first, second, and third trenches.

[0103] Optionally, after step S1000, the method further includes: using an OTDR to detect the quality of the optical cable laying.

[0104] Step S1100: If fusion splicing is required, fusion splice the temperature-sensing optical fiber to connect the temperature-sensing optical fibers in the first and second trenches.

[0105] Step S1200: Backfill the trenches that need to be backfilled in the second batch.

[0106] In this embodiment, by excavating the second batch of trenches to be excavated, splicing the temperature-sensing optical fibers, and backfilling the second batch of trenches to be backfilled, the laying of temperature-sensing optical fibers in the first, second, and third trenches is completed, as well as the construction of the thermal pipeline system with a leak detection system is completed. This reduces the splicing points of the temperature-sensing optical fibers and improves the monitoring quality of the distributed temperature measurement system for the temperature and leak points of the thermal pipeline.

[0107] Optionally, after step S1200, the method further includes: using an OTDR to detect the quality of the optical cable laying; detecting the presence of sheet piles; and removing the sheet piles if they are present.

[0108] Figure 6 This is a schematic diagram of the first method of pipe jacking construction provided in this application embodiment.

[0109] Optionally, the target construction method also includes pipe jacking construction. After step S100, it also includes steps S1300 to S1800, as follows: Step S1300: If the target construction method is pipe jacking, install the pipe jacking on the preset line.

[0110] In this step, specialized tunneling equipment (such as a pipe jacking machine or a tunnel boring machine) is first used to excavate the soil ahead. The front end of the pipe jacking machine is equipped with a cutterhead or cutting tools to excavate a space the size of the pipe in the soil. Then, a huge thrust is applied by hydraulic jacks to gradually advance the pipe into the soil. The hydraulic jacks provide strong pushing from behind, while the tunneling machine at the front continues to excavate. The cutterhead at the front of the tunneling machine moves the excavated soil to the rear of the pipe, usually by using mud or conveyor belts to remove the soil and prevent blockages. Pipe jacking typically consists of multiple pipe sections connected together; after each advancement of a certain distance, a new pipe section is jacked into the previous section.

[0111] For example, combined Figure 6 As shown in (a), the jacking pipe 16 is installed on the preset line 01.

[0112] Step S1400: Set cement nails at the preset fixing points on the inner wall of the jacking pipe.

[0113] Step S1500: Use cement nails to fix the replacement temperature-sensing optical fiber; the replacement temperature-sensing optical fiber includes a silicon core tube and a replacement optical cable.

[0114] In this step, since there is sufficient installation space inside the jacking pipe, workers are arranged to enter the jacking pipe to fix cement nails, and use cement nails to fix the replacement temperature measuring fiber, thus realizing the installation of the replacement temperature measuring fiber.

[0115] Specifically, using cement nails to fix the alternative temperature-sensing fiber optic cable can be achieved by using wire to fix the cement nails to the alternative temperature-sensing fiber optic cable. For example, combined Figure 6 As shown in (b), the temperature-sensing fiber optic cable 08 is installed on the upper part of the inner wall of the jacking pipe 16. Specifically, in conjunction with... Figure 6 As shown in (d), when the temperature measuring fiber 08 includes a first temperature measuring fiber 06 and a second temperature measuring fiber 07, and the heat pipe 05 includes a water supply pipe 03 and a return water pipe 04, the first temperature measuring fiber 06 is used to measure the temperature of the water supply pipe 03, and the second temperature measuring fiber 07 is used to measure the temperature of the return water pipe 04. In this case, the first temperature measuring fiber 06 and the second temperature measuring fiber 07 can be positioned above the water supply pipe 03 and the return water pipe 04 respectively to achieve separate detection.

[0116] Step S1600: Install the heating pipe inside the jacking pipe.

[0117] In this step, the heating pipe is pushed into the jacking pipe.

[0118] For example, combined Figure 6 As shown in (c) and (e), a heat pipe 05 is installed inside the jacking pipe 16.

[0119] Step S1700: Replace the optical cable with an optical fiber cable.

[0120] In this step, a substitute optical cable is used for pre-installation to reduce damage to the optical cable during the installation of the heating pipes. After the heating pipes are installed, the optical cable is used to replace the substitute optical cable to complete the installation of the actual optical cable. Subsequent installation steps will not damage the optical cable that is actually needed, thus extending the service life of the optical cable and reducing the later maintenance costs of the system.

[0121] Step S1800: Backfill the jacking pipe with sand.

[0122] In this embodiment, pipe jacking is used to lay thermal pipelines in environments unsuitable for trenching, thus eliminating the need for trench excavation, reducing the complexity of trenching, and adapting to environments unsuitable for trenching.

[0123] Optionally, after step S1800, the method further includes: using an OTDR to detect the quality of the optical cable laying; detecting the presence of sheet piles; and removing the sheet piles if they are present.

[0124] Specifically, during pipe jacking construction, if the heating pipe leaks, the leaking water will flow into the pipe, affecting the temperature inside the pipe, and thus the leak can be detected by the temperature-measuring fiber optic cable.

[0125] Figure 7This is a schematic diagram of a second type of pipe jacking construction process provided in an embodiment of this application.

[0126] Optionally, the target construction method also includes pipe jacking construction. After step S100, it also includes steps S1900 to S2200, as follows: Step S1900: If the target construction method is pipe jacking, install the pipe jacking pipe on the preset line.

[0127] Specifically, step S1900 is implemented in the same way as step S1300 described above, and will not be repeated here.

[0128] For example, combined Figure 7 As shown in (a), the jacking pipe 16 is installed on the preset line 01.

[0129] Step S2000: Install the heating pipe inside the jacking pipe.

[0130] Specifically, step S2000 is implemented in the same way as step S1600 described above, and will not be repeated here.

[0131] For example, combined Figure 7 As shown in (b), a heating pipe 05 is installed inside a jacking pipe 16. Exemplarily, the heating pipe 05 includes a water supply pipe 06 and a water return pipe 07. In this case, a water supply pipe 03 and a water return pipe 04 are installed inside the jacking pipe 16.

[0132] Step S2100: Use a trolley to pass the temperature-sensing fiber through the top pipe and install the temperature-sensing fiber.

[0133] Specifically, since the heating pipes are installed inside the jacking pipe first, there is not enough space for workers to carry the temperature-sensing optical fiber through. Therefore, a sliding trolley is needed to carry the temperature-sensing optical fiber through the jacking pipe to install the optical fiber.

[0134] For example, combined Figure 7 As shown in (c), the temperature-sensing fiber optic cable 08 is installed inside the jacking pipe 16. Specifically, in conjunction with... Figure 7 As shown in (d), when the temperature measuring fiber 08 includes a first temperature measuring fiber 06 and a second temperature measuring fiber 07, the first temperature measuring fiber 06 is used to measure the temperature of the water supply pipe 03, and the second temperature measuring fiber 07 is used to measure the temperature of the return water pipe 04. In this case, the first temperature measuring fiber 06 and the second temperature measuring fiber 07 can be positioned above the water supply pipe 03 and the return water pipe 04 respectively to achieve separate detection.

[0135] Figure 8 This is a schematic diagram of the operation of the gliding vehicle provided in the embodiments of this application.

[0136] For example, combined Figure 8As shown, the sliding vehicle 17 can move controllably along the heating pipe 05, sliding within the space between the heating pipe 05 and the upper wall of the jacking pipe 16, thereby driving the temperature-sensing optical fiber through the jacking pipe 16. With the temperature-sensing optical fiber 08 through the jacking pipe 16, sand is blown into the jacking pipe 16 to fill the remaining space inside the jacking pipe 16, thus fixing the heating pipe 05 and the temperature-sensing optical fiber 08 within the jacking pipe 16.

[0137] Step S2200: Backfill the jacking pipe using a sand blowing process.

[0138] This step, using a sand-blowing process for backfilling the jacking pipe, includes: preparing the sand-blowing equipment; the sand-blowing equipment includes a compressed air source, a delivery pipeline, and nozzles. Selecting the backfill sand material. Connecting the delivery pipeline to the sand-blowing equipment and aiming the nozzles at the backfill area around the jacking pipe. Starting the compressed air source to compress air, blowing the sand material into the vicinity of the jacking pipe at a preset blowing speed through the delivery pipeline.

[0139] In this embodiment, a sliding trolley is designed to fix the temperature-measuring optical fiber to the jacking pipe, so as to realize the measurement of the temperature and leakage points of the thermal pipeline using a distributed optical fiber temperature measurement system.

[0140] Optionally, after step S2200, the method further includes: using an OTDR to detect the quality of the optical cable laying; detecting the presence of sheet piles; and removing the sheet piles if they are present.

[0141] Corresponding to the aforementioned embodiments of the construction method for the heating system, this application also provides an embodiment of a heating pipeline system with a leak detection system. This heating pipeline system with a leak detection system, obtained using any of the aforementioned construction methods for the heating system, includes: a heating pipeline and a temperature-sensing optical fiber; the heating pipeline is buried underground; the temperature-sensing optical fiber is fixedly installed with the heating pipeline; the heating pipeline is configured for urban heating; and the temperature-sensing optical fiber is configured as a temperature-sensing point for measuring the temperature of the heating pipeline.

[0142] The system for thermal pipelines with a leak detection system provided in this application reduces the number of splice points on the temperature-sensing optical fiber, thereby reducing the problem of optical signal variation within the temperature-sensing optical fiber due to splice points and improving the detection accuracy of the temperature-sensing optical fiber for thermal pipelines.
