Abstract
Description
Technical Field
[0001] The utility model relates to the field of pipeline installation, and in particular to a pipeline installation structure for crossing a road. Background Art
[0002] In recent years, the management of pressure pipelines in long-distance pipeline stations has received increasing attention from management departments and enterprises. How to ensure the safe and stable operation of pressure pipelines in stations and reduce the probability of environmental accidents requires practitioners to work hard to solve. The existing pipelines in stations crossing roads are usually laid underground using casing and pipe supports, which makes it difficult to inspect and test using existing means. The corrosion risk of buried steel pipelines is not easy to be discovered, and the pressure pipelines in stations cannot be tested through the ball. Therefore, corrosion leaks cannot be discovered in the first time. By the time the leaking medium is discovered on the surface, a large amount of leakage may have occurred, and it is very likely that a large safety and environmental accident will occur, causing serious losses to society and enterprises. Utility Model Content
[0003] In view of this, the utility model provides a pipeline installation structure for crossing roads which is convenient for pipeline detection and has simple and convenient daily maintenance and management.
[0004] The purpose of the utility model is achieved through the following technical solutions:
[0005] A pipeline installation structure for crossing a road includes a culvert dug on the ground and a pipeline passing through the culvert, wherein the pipeline includes a first straight pipe erected in the culvert, two curved pipes respectively connected to two ends of the first straight pipe, and two second straight pipes respectively connected to the two curved pipes, and the two second straight pipes are laid on the ground; the culvert includes a base plate, a wall body arranged on the base plate, and a cover plate detachably covered on the wall body, and the cover plate includes a plate body layer and a pavement layer.
[0006] In the above technical solution, the pipeline includes a first straight pipe part erected in the culvert, and a second straight pipe part laid on the ground. The height difference between the first straight pipe and the second straight pipe is as small as possible through the design of the curved pipe, so that the pipeline can avoid deep burial while passing through the road surface. Compared with the traditional buried pipeline crossing the road, the corrosion environment of the exposed pipeline of the utility model is generally an atmospheric corrosion environment. Compared with the buried pipeline, it can be simpler and more convenient to implement daily maintenance and management, and can be more convenient to implement inspection and repair, which minimizes the risk of corrosion leakage and ensures the safe operation of the pipeline. In addition, the culvert is composed of a base plate, a wall and a detachable cover plate, with a simple structure. The detachability of the cover plate also facilitates future pipeline maintenance and overhaul work, and the pavement layer design allows the pipeline to quickly resume normal use of the road after installation.
[0007] Optionally, in a possible implementation, the pavement layer covers the surface of the plate body layer, the width directions of the plate body layer and the pavement layer both extend along the length direction of the first straight tube, and the width of the pavement layer is smaller than the width of the plate body layer.
[0008] In the above technical solution, since the width of the plate layer is greater than that of the pavement layer, this design can provide stronger structural stability through the larger area of the plate layer while ensuring the bearing capacity of the pavement layer. And since the pavement layer is narrower, the amount of material used is correspondingly reduced, which reduces the cost of replacing or repairing the pavement layer.
[0009] Optionally, in a possible implementation, a plurality of hanging rings are provided on the plate body layer, and the plurality of hanging rings are respectively located at two side edges in the width direction of the plate body layer.
[0010] In the above technical solution, by setting lifting rings on the edges of both sides of the plate layer, the plate layer can be conveniently lifted and transported using lifting equipment, and it can also be conveniently disassembled when the pipeline needs to be overhauled in the future. The setting of multiple lifting rings enables the plate layer to adapt to different lifting requirements.
[0011] Optionally, in a possible implementation, the wall is provided with ventilation holes, the ventilation holes are located on two opposite sides in the width direction of the plate layer, and the curved pipes are led out from the ventilation holes.
[0012] In the above technical solution, the setting of the vents enables the culvert to have ventilation function, which is not easy to produce gas accumulation, can meet the requirements of regular inspections, facilitate the detection of combustible gases, and also meet the conditions for regular inspection and local maintenance of pipelines. It also helps to reduce the growth of microorganisms such as mold, bacteria and viruses, thereby maintaining the health of the internal structure.
[0013] Optionally, in a possible implementation, a plurality of first support brackets are provided on the bottom plate, and the first support brackets are used to support the first straight pipes and suspend the first straight pipes in the culvert.
[0014] In the above technical solution, the first straight pipe is suspended in the culvert by the first supporting bracket, which can effectively prevent the friction and damage that may be caused by direct contact between the first straight pipe and the ground, while ensuring the stability of the pipeline in the culvert, and can reduce the stress on the first straight pipe caused by factors such as foundation settlement or ground vibration, thereby ensuring the long-term stable operation of the first straight pipe.
[0015] Optionally, in a possible implementation, the first supporting bracket includes a first supporting seat arranged on the base plate, and a first supporting plate arranged on the first supporting seat, and the first supporting plate is an arc-shaped plate structure matching the first straight tube.
[0016] In the above technical solution, the first support plate is designed as an arc-shaped plate structure that matches the first straight pipe. The customized matching method can ensure that the first straight pipe is firmly supported on the first support plate, reducing sliding or shaking caused by excessively large or small gaps between the first straight pipe and the first support plate, thereby enhancing the stability of the first pipeline.
[0017] Optionally, in a possible implementation, the second straight pipe is supported by a second supporting bracket, the second supporting bracket includes a second supporting seat buried in the ground, and a second supporting plate arranged on the second supporting seat, and the second supporting plate is an arc-shaped plate structure matching the second straight pipe.
[0018] Similarly, the second support plate is designed as an arc-shaped plate structure matching the second straight pipe. The second support plate is used to support the second straight pipe located on the ground, and the first support plate is used to support the first straight pipe located in the culvert. The first support bracket and the second support bracket work together to effectively improve the stability of the pipeline and reduce the contact between the pipeline and the ground.
[0019] Optionally, in a possible implementation, the pipes are multiple and spaced apart, and the multiple pipes are all located in the culvert. A load-bearing wall is also provided in the culvert, and the load-bearing wall is located between the bottom plate and the cover plate.
[0020] In the above technical solution, there are usually multiple pipeline systems crossing the road, and setting all the multiple pipelines in the same culvert can facilitate the simultaneous installation of multiple pipelines. As the volume of the culvert increases, in order to increase the bearing capacity of the cover plate, load-bearing walls can be added. This can not only improve the bearing capacity of the cover plate, but also save space at the bottom of the culvert.
[0021] Optionally, in a possible implementation, the surface of the pipeline is coated with epoxy zinc-rich primer, epoxy high-build intermediate paint and polyurethane topcoat in sequence.
[0022] In the above technical scheme, the epoxy zinc-rich primer has a high content of zinc powder, which can effectively inhibit the electrochemical corrosion of the metal surface and provide long-term anti-corrosion protection for the pipeline; the epoxy thick paste intermediate paint not only has excellent anti-corrosion performance, but also has good weather resistance and durability, which can fill the tiny defects on the primer surface, improve the overall smoothness and aesthetics of the coating system, and enhance the wear resistance and impact resistance of the coating; the polyurethane topcoat has good decorative and protective properties, which can provide the pipeline with a smooth and bright appearance, while enhancing its weather resistance and corrosion resistance.

[0024] The pipeline of the utility model is installed by laying on the ground and passing through the culvert, that is, an open-air pipeline is used to avoid deep burial of the pipeline. Compared with the corrosive environment of the buried ground, the open-air pipeline is generally in an atmospheric corrosive environment. Compared with the buried pipeline, it can be simpler and more convenient to implement daily maintenance and management, and can be more convenient to implement inspection and repair, which minimizes the risk of corrosion and leakage and ensures the safe operation of the pipeline. At the same time, the installation method of the pipeline is also simpler. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.
[0030] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.
[0031] Please refer to Figure 1The present embodiment provides a pipe 2 installation structure for crossing a road, including a culvert 1 dug on the ground and a pipe 2 passing through the culvert 1, wherein the pipe 2 includes a first straight pipe 21 erected in the culvert 1, two curved pipes 23 respectively connected to both ends of the first straight pipe 21, and two second straight pipes 22 respectively connected to the two curved pipes 23, the two second straight pipes 22 are laid on the ground, wherein the two curved pipes 23 are arranged at 45 degrees relative to the first straight pipe 21; the culvert 1 includes a bottom plate 11, a wall 12 arranged on the bottom plate 11, and a cover plate 13 detachably covered on the wall 12, wherein the cover plate 13 includes a plate layer 131 and a pavement layer 132.
[0032] It should be noted that the pavement layer 132 is the pavement of a normal road, the culvert 1 is located below the normal road, and the culvert 1 spans the entire width of the road, that is, the pipeline 2 passes under the road by setting the culvert 1. In addition, the bottom plate 11 and the wall 12 are both reinforced concrete structures, the plate layer 131 in the cover plate 13 is a reinforced concrete structure, and the pavement layer 132 is a C30 plain concrete structure. In addition, the cover plate 13 can be set in a block structure, and the load-bearing capacity meets the load-bearing requirements of the foam transport vehicle rolling.
[0033] The pipeline 2 of this embodiment includes a first straight pipe 21 part erected in the culvert 1, and a second straight pipe 22 part laid on the ground. The design of the bend 23 makes the height difference between the first straight pipe 21 and the second straight pipe 22 as small as possible, so that the pipeline 2 can avoid deep burial while passing through the road surface. Compared with the traditional buried pipeline crossing the road, the corrosion environment of the exposed pipeline of this embodiment is generally an atmospheric corrosion environment. Compared with the buried pipeline, it can be simpler and more convenient to implement daily maintenance and management, and can be more convenient to implement inspection and maintenance, which minimizes the risk of corrosion leakage and ensures the safe operation of the pipeline. In addition, the culvert 1 is composed of a base plate 11, a wall 12 and a detachable cover plate 13, and has a simple structure. The detachability of the cover plate 13 also facilitates the maintenance and inspection of the pipeline 2 in the future, and the design of the pavement layer 132 allows the pipeline 2 to quickly resume normal use of the road after installation.
[0034] In this embodiment, the pavement layer 132 covers the surface of the plate body layer 131, and the width directions of the plate body layer 131 and the pavement layer 132 extend along the length direction of the first straight tube 21. The width of the pavement layer 132 is smaller than the width of the plate body layer 131, that is, the width directions of the pavement layer 132 and the plate body layer 131 are consistent with the width directions of normal roads.
[0035] Since the width of the plate layer 131 is greater than that of the pavement layer 132, this design can provide stronger structural stability through the larger area of the plate layer 131 while ensuring the bearing capacity of the pavement layer 132. And since the pavement layer 132 is narrower, the amount of material used is reduced accordingly, which reduces the cost of replacing or repairing the pavement layer 132. At the same time, the narrower pavement layer 132 also means smaller thermal expansion and contraction deformation, thereby reducing cracks and damage caused by temperature changes and improving the durability of the pavement layer 132. In addition, the width difference between the pavement layer 132 and the plate layer 131 provides space for drainage. When rainwater or other liquids fall on the road surface, these liquids can be quickly drained through the gap between the pavement layer 132 and the plate layer 131, avoiding erosion and damage to the road surface caused by accumulated water, while also improving driving safety.
[0036] In this embodiment, a plurality of lifting rings 3 are provided on the plate layer 131, and the plurality of lifting rings 3 are respectively located at the two side edges in the width direction of the plate layer 131. By providing the lifting rings 3 at the two side edges of the plate layer 131, the plate layer 131 can be conveniently lifted and transported by lifting equipment, and can also be conveniently disassembled when the pipeline 2 needs to be overhauled in the future, and the provision of the plurality of lifting rings 3 enables the plate layer 131 to adapt to different lifting requirements.
[0037] In this embodiment, the wall 12 is provided with vents 4, which are located on opposite sides of the width direction of the plate layer 131, and the bent pipe 23 is led out from the vents 4. It can be understood that the wall 12 can be a structure with four sides closed, and the vents 4 are relatively arranged on both sides in the width direction of the road. Of course, the wall 12 can also be a structure with two relatively closed sides, and the two unclosed opposite sides can be used as vents 4.
[0038] The provision of the vents 4 enables the culvert 1 to have a ventilation function, is not prone to gas accumulation, can meet the requirements of regular inspections, facilitate the detection of combustible gases, and also meet the conditions for regular inspections and local maintenance of the pipeline 2. It also helps to reduce the growth of microorganisms such as mold, bacteria and viruses, thereby maintaining the health of the interior of the structure.
[0039] In this embodiment, a plurality of first support brackets 5 are provided on the bottom plate 11, and the first support brackets 5 are used to support the first straight pipe 21 and suspend the first straight pipe 21 in the culvert 1. Suspending the first straight pipe 21 in the culvert 1 by the first support brackets 5 can effectively prevent the friction and damage that may be caused by the direct contact between the first straight pipe 21 and the ground, and at the same time ensure the stability of the pipeline 2 in the culvert 1, and can reduce the stress on the first straight pipe 21 caused by factors such as foundation settlement or ground vibration, thereby ensuring the long-term stable operation of the first straight pipe 21.
[0040] Specifically, the first support bracket 5 includes a first support seat 51 disposed on the bottom plate 11, and a first support plate 52 disposed on the first support seat 51, and the first support plate 52 is an arc-shaped plate-shaped structure matching the first straight pipe 21. The first support plate 52 is designed as an arc-shaped plate-shaped structure matching the first straight pipe 21, and the customized matching method can ensure that the first straight pipe 21 is firmly supported on the first support plate 52, reducing the sliding or shaking caused by the excessively large or small gap between the first straight pipe 21 and the first support plate 52, thereby enhancing the stability of the first pipeline 2.
[0041] In this embodiment, the second straight pipe 22 is supported by a second supporting bracket 6, which includes a second supporting seat 61 buried in the ground and a second support plate 62 arranged on the second supporting seat 61. The second support plate 62 is an arc-shaped plate structure matching the second straight pipe 22.
[0042] Similarly, the second support plate 62 is designed as an arc-shaped plate structure matching the second straight pipe 22. The second support plate 62 is used to support the second straight pipe 22 located on the ground. The first support plate 52 is used to support the first straight pipe 21 located in the culvert 1. The first support bracket 5 and the second support bracket 6 work together to effectively improve the stability of the pipeline 2 and reduce the contact between the pipeline 2 and the ground.
[0043] In this embodiment, there are multiple pipes 2 arranged at intervals, and the multiple pipes 2 are all located in the culvert 1. A load-bearing wall 8 is also provided in the culvert 1, and the load-bearing wall 8 is located between the bottom plate 11 and the cover plate 13. Among them, the load-bearing wall 8 is a "T"-shaped concrete structure. In actual use, there are usually multiple pipes 2 systems crossing the road, and the multiple pipes 2 are all arranged in the same culvert 1, which can facilitate the simultaneous installation of the multiple pipes 2. As the volume of the culvert increases, in order to increase the bearing capacity of the cover plate 13, it can be achieved by adding a load-bearing wall 8, which can not only improve the bearing capacity of the cover plate 13, but also save space at the bottom of the culvert 1.
[0044] In this embodiment, the surface of the pipeline 2 is coated with epoxy zinc-rich primer, epoxy high-build intermediate paint and polyurethane topcoat in sequence, wherein the total thickness of the paint film is 250-300 μm.
[0045] It should be noted that the epoxy zinc-rich primer has a high content of zinc powder, which can effectively inhibit the electrochemical corrosion of the metal surface and provide long-term anti-corrosion protection for the pipeline 2; the epoxy thick paste intermediate paint not only has excellent anti-corrosion performance, but also has good weather resistance and durability, which can fill the tiny defects on the primer surface, improve the overall smoothness and aesthetics of the coating system, and enhance the wear resistance and impact resistance of the coating; the polyurethane topcoat has good decorative and protective properties, which can provide a smooth and bright appearance for the pipeline 2, while enhancing its weather resistance and corrosion resistance. The construction of the three-layer coating is relatively simple, and the next layer can be constructed after each layer of coating is dried, without the need for complicated pretreatment and post-treatment steps. At the same time, the maintenance of the coating system is relatively easy, and it only requires regular inspection of the coating status and necessary repairs.
