Description

Technical Field

[0001] The utility model relates to the technical field of communication pipes, in particular to a PE communication pipe with a porous structure. Background Art

[0002] PE communication pipe is a pipe made of polyethylene resin as raw material, mainly used as a communication pipe.

[0003] PE communication pipe is also called HDPE (high-density polyethylene) communication pipe. This pipe has many advantages and strong applicability, and is particularly suitable for laying cables, wires and other cables. It is mainly used for the layout of underground communication lines such as urban telecommunication optical cables, cable television lines, and traffic signal lines. It plays a key role in improving the reliability and stability of communication lines and extending the service life of the lines.

[0004] PE communication pipes are mainly designed to protect the cables and optical fibers inside, but most of these communication pipes are buried underground. When construction is carried out above them, the specific location of the optical cable or electrical cable cannot be determined. In order to effectively avoid it, when the depth of the cable is reached, small machinery will be used for manual excavation. Only after the communication pipe itself is excavated can the specific location of the communication pipe be determined and effective avoidance can be carried out.

[0005] However, with the modernization of construction, workers generally use small excavators that save as much labor as possible. When the excavators touch a conventional communication pipe, there is a probability that the outer layer of the communication pipe will be penetrated. Although it will not cause damage to the internal cables or wires, the outer layer of the communication pipe will eventually be damaged. Although the construction workers can find the communication pipe during excavation, they cannot know whether the interior of the communication pipe is damaged. In order to solve this technical problem, the utility model proposes a PE communication pipe with a porous structure. Utility Model Content

[0006] The main purpose of the utility model is to provide a method that can effectively solve the problems mentioned in the background technology.

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1-4As shown, a PE communication tube with a porous structure comprises a tube core 1, a cross plate 2 is fixedly connected to the outer surface of the tube core 1, a tube sleeve 3 is arranged outside the cross plate 2, the tube sleeve 3 can wrap the entire communication tube, and is the outermost protective layer of the communication tube as a whole, a cable body 4 and a magnesium plate 5 are arranged inside the tube sleeve 3, a hose 6 is fixedly connected to the outer surface of the cross plate 2, a first filling area 7 is reserved between the cross plate 2, the hose 6 and the tube core 1, and the first filling area 7 is filled with a soaked sponge, the sponge can be easily deformed, and can squeeze out water and deform in time when squeezed by external force, when the external force disappears, the sponge can absorb the squeezed water, so that it can absorb heat inside the communication tube as a whole, so that the communication tube as a whole has the characteristic of being able to regulate temperature, and the cross The outer surface of the plate 2 is fixedly connected with a connecting sleeve 8, and the cable body 4 is fixedly connected to the inner wall of the connecting sleeve 8. The connecting sleeve 8 can provide support for the cable to prevent the cable from shifting or deforming. At the same time, a space is reserved between the connecting sleeves 8, which can make the whole have good flexibility and will not damage the cable itself. The outer surface of the connecting sleeve 8 is covered with a sealing layer 9, and the sealing layer 9 is mainly PVC-O pipe. PVC-O pipe is a pipe made of soft material with very strong toughness and is not easy to be cut. PVC-O pipe, Chinese name biaxially oriented polyvinyl chloride, is the latest evolution of PVC pipe. It is a pipe made by a special orientation processing technology. The PVC-U pipe produced by extrusion is processed Axial stretching and radial stretching make the PVC long-chain molecules in the pipe arranged regularly in both axial directions, so as to obtain a new type of PVC pipe with high strength, high toughness, high impact resistance and fatigue resistance. Due to its super toughness, it is called "unbreakable pipe", which can effectively protect the cable itself from being affected. The outer surface of the sealing layer 9 is fixedly connected with the thermal insulation layer 10, and the outer surface of the thermal insulation layer 10 is fixedly connected to the outer surface of the cross plate 2. The magnesium plate 5 is fixedly connected to the cross plate 2 and the outer surface of the thermal insulation layer 10. The interior of the thermal insulation layer 10 is filled with thermal insulation sand and aerogel insulation materials, which can isolate the high temperature of up to 200 degrees Celsius transmitted from the outside in a short time, thereby further protecting the cable. The interior of the magnesium plate 5 is provided with a cavity 11, and the magnesium plate 5 is located A protrusion 12 is provided on the side facing the pipe sleeve 3. The protrusion 12 on the magnesium plate 5 can produce sparks when the cutting object is close to and cut, so as to promptly remind the construction personnel to stop digging. The partition layer in the inner cavity is filled with compressed oxygen. After the excavation equipment drills into the magnesium plate 5 and enters the cavity 11, the oxygen can make the sparks rubbed by the magnesium plate 5 more intense, thereby further reminding the construction personnel to stop digging, and the overall damage of the communication pipe can be judged by the size of the sparks. The outer surface of the pipe sleeve 3 is provided with a positioning point 13. The positioning point 13 can facilitate the grasping of the communication pipe body when placing the communication pipe, and the positioning point 13 can be used to facilitate the identification of the approximate position of the internal cable. The inner wall of the pipe sleeve 3 located at the positioning point 13 is provided with a sliding sleeve 14.The outer surface of the sliding sleeve 14 is slidably connected to the outer surface of the cross plate 2. When the sleeve 3 is under pressure, it can be compressed and deformed inward on the cross plate 2 through the sliding sleeve 14. The inside of the sliding sleeve 14 and the inside of the cross plate 2 are provided with a reserved area 15. The reserved area 15 is filled with air and can shrink when under pressure, and expand back to the original position when the external pressure is reduced to zero. A second filling area 16 is provided between the magnesium plate 5, the cross plate 2 and the sleeve 3. A small amount of lime is filled inside the second filling area 16, so that the lime itself has obvious recognition when it is lifted, so as to further remind the construction personnel to stop digging.

[0024] It should be noted that in actual use of the device, the excavating equipment will inevitably contact the pipe sleeve 3. When the pipe sleeve 3 is under pressure, it can be compressed and deformed inward on the cross plate 2 through the sliding sleeve 14. During this period, resistance will be generated to provide the first warning message for the construction personnel. When the excavating equipment further cuts and penetrates into the interior of the pipe sleeve 3, the lime inside the second filling area 16 will be brought out and lifted up. The white lime can provide the second warning message for the construction personnel. When continuing to cut, it can contact the protrusions on the magnesium plate 5, thereby generating sparks to provide the third warning message for the construction personnel. When continuing to cut into the inner cavity of the magnesium plate 5, a large number of sparks will burst out due to the action of oxygen, thereby providing the fourth and final warning message for the construction personnel. The four different warning methods can provide four different degrees of damage to the construction personnel, which is beneficial for the on-site personnel to know the degree of damage to the communication pipe.
