For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0022] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] Reference Figures 1 to 3 This application provides a PE protective plate for gas transmission pipelines with good protective effect, including a protective plate body 1. The protective plate body 1 has a multi-layer composite structure, consisting of a protective layer 11, a reinforcing layer 12, a buffer layer 13, and a warning layer 14 from the outside to the inside. The protective layer 11 is made of high-strength wear-resistant modified polyethylene material and has an anti-slip texture on the surface. The reinforcing layer 12 is a composite material layer made of high-strength fiber fabric and thermosetting resin. The buffer layer 13 is made of rubber or foam plastic. The warning layer 14 is a polyethylene layer containing fluorescent agent, with a warning mark 4 on its surface and a copper-clad steel tracer wire embedded inside.

[0024] The protective panel body 1 has splicing grooves 2 and splicing protrusions 3 on both sides along its length. The splicing grooves 2 and splicing protrusions 3 are adapted to each other, and the splicing grooves 2 are equipped with sealing strips. Multiple fixing hooks 5 are spaced apart at the bottom of the protective panel body 1. The fixing hooks 5 have an inverted "L" shape and are made of high-strength steel. Microcapsules are dispersed within the protective layer 11 and the buffer layer 13. The microcapsules are micron-sized capsules made of high-strength chemical corrosion-resistant material and filled with a repair agent. The depth of the splicing grooves 2 is 3-5 cm, and the height of the splicing protrusions 3 matches the depth of the splicing grooves 2. The ends of the splicing protrusions 3 are rounded. There are 4-8 fixing hooks 5, evenly distributed along the length of the protective panel body 1. The length of the fixing hooks 5 is 8-12 cm.

[0025] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0026] Working principle: The PE protective plate for gas transmission pipelines achieves its protective function through the synergistic effect of its multi-layer composite structure. When external friction or mechanical impact occurs, the outermost protective layer 11 is the first to be affected. The protective layer 11 is made of high-strength wear-resistant modified polyethylene material, which has a compact molecular structure and good toughness, effectively resisting the scratches and impacts of external objects. The anti-slip texture on the surface increases the friction with the outside world. When faced with the movement of construction machinery or the contact of digging tools, it reduces the relative sliding between the protective plate and external objects, reduces the heat and wear generated by friction, and thus protects the inner structure.

[0027] The reinforcing layer 12 is composed of high-strength fiber fabric and thermosetting resin. The high-strength fiber fabric, such as glass fiber and carbon fiber, has extremely high tensile strength and plays a supporting role in the composite structure. The thermosetting resin fills the gaps in the fiber fabric and, after curing, tightly bonds the fibers together to form a whole. When the protective plate is subjected to heavy pressure from above or squeezing force from the side, the reinforcing layer 12 can, with its high strength characteristics, evenly distribute the external force to the entire protective plate body 1, preventing excessive local stress from causing structural damage and effectively improving the overall rigidity and load-bearing capacity of the protective plate.

[0028] The rubber or foam material of the buffer layer 13 has excellent elasticity. When the impact force breaks through the protective layer 11 and reaches the buffer layer 13, the chain segment structure between the rubber or foam molecules can be displaced and deformed under the action of external force. This deformation process absorbs a large amount of impact energy and converts the impact force into intermolecular internal stress. For example, when subjected to an instantaneous impact, the rubber molecular chain will be stretched and twisted, and the bubble structure of the foam will be compressed, thereby dispersing and consuming the impact energy, greatly reducing the impact force transmitted to the inner warning layer 14 and the gas transmission pipeline, and preventing the pipeline from rupturing due to impact.

[0029] During the splicing process, the splicing groove 2 and the splicing protrusion 3 play a crucial role. The dimensions of the splicing groove 2 and the splicing protrusion 3 are precisely matched. When two adjacent protective plates are spliced, the splicing protrusion 3 can be tightly embedded in the splicing groove 2 to achieve precise alignment. The sealing strips installed in the splicing groove 2 are mostly made of rubber materials with good flexibility and adhesion. After the splicing protrusion 3 is inserted, the sealing strips are squeezed and deformed, filling the tiny gaps at the splicing part and forming a sealing barrier. This effectively prevents external moisture, dirt, and corrosive substances from entering the interior of the protective plate through the splicing point, avoiding damage to the internal structure due to moisture and corrosion, and ensuring the long-term stability and sealing of the splicing part of the protective plate.

[0030] The fixing hook 5 adopts an inverted "L" shape and is made of high-strength steel. During installation, one end of the fixing hook 5 is inserted into the foundation structure around the pipeline, such as soil or concrete base. Due to the special shape of the fixing hook 5, its horizontal part can hook the bottom of the foundation structure. When the protective plate is subjected to external force attempting to displace it, the fixing hook 5 will be subjected to an upward pull. The high-strength steel ensures that the fixing hook 5 will not easily deform or break, and can firmly resist the pull, stably fixing the protective plate above the pipeline. This prevents the protective plate from shifting due to ground settlement, external impact, or other factors, and continuously provides reliable protection for the gas transmission pipeline.

[0031] The fluorescent polyethylene layer of warning layer 14 absorbs weak light from the surrounding environment in low-light conditions and converts it into visible light, making the warning sign 4 on the surface of warning layer 14 more conspicuous and easily noticed by construction workers or other operators. This provides a direct visual warning, reminding them that there is a gas pipeline below and prohibiting any unauthorized digging or operations that may damage the pipeline. The copper-clad steel tracer wire embedded inside has good conductivity and can emit electromagnetic waves of a specific frequency through electromagnetic induction detection equipment on the ground. When the electromagnetic waves encounter the copper-clad steel tracer wire, an induced current is generated in the tracer wire, which in turn forms a secondary electromagnetic field that is captured by the detection equipment. This allows for precise determination of the location of the protective plate and the gas pipeline below, greatly improving the accuracy and convenience of pipeline positioning.

[0032] The microcapsules dispersed within the protective layer 11 and buffer layer 13 are made of high-strength, chemically resistant materials. When the protective layer 11 or buffer layer 13 is subjected to minor external forces during use and develops microcracks, the microcapsules at the cracks will rupture due to stress such as compression and tension. The repair agent filled inside the microcapsules, such as epoxy resin adhesive, will be released after rupture, react with the surrounding materials, solidify at the cracks, fill the microcracks, restore the integrity and protective performance of the protective plate, effectively extend the service life of the protective plate, and reduce the risk of further damage caused by failure to repair minor damage in time.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
