Technical Field
The invention relates to a pipeline protection technology, in particular to a buried pipeline protection plate and an installation method thereof.
Background
The buried pipeline is used as a transmission carrier of oil gas and is a link for connecting upstream resources and downstream users. Because the pipeline is buried underground for a long time, the accidents of pipeline perforation and leakage caused by artificial damage, mechanical excavation and the like exist, not only can serious economic loss be brought, but also the leakage of harmful substances can be caused, the environment can be polluted, even sudden disastrous accidents can be caused, and the personal safety can be endangered.
At present, most domestic pipelines are not provided with protection facilities, and the protection measures to be added to the pipelines are not explicitly proposed in relevant construction standards. In the field, in the prior art, bearing steel and reinforced concrete slabs are adopted as protective measures for buried pipelines, so that time and labor are consumed in the installation process, and the field construction is not facilitated; and the reticular plastic net is directly wound on the outer wall of the pipeline, so that small impact on the pipeline can only be prevented when backfilling is carried out, and once the plastic net is damaged, the stress source can be directly applied to the pipeline, and the early warning effect cannot be realized.
The unit mass of the protective plate used in the prior art is large, and the field transportation and installation are inconvenient; the feedback information is not timely, the information of the pipeline cannot be clearly prompted, and the risk of further damaging the pipeline is increased.

step four: and covering soil on the upper layer of the backfilled buried pipeline protection plate, and restoring the landform to the state before excavation.
Compared with the prior art, the invention has at least the following beneficial effects: the buried pipeline protection device can well prevent the pipeline from being damaged by external machinery or artificial excavation through the lower layer protection plate and the lower layer protection plate which are arranged above the buried pipeline. When the upper protective plate is damaged to excavate downwards, the excavating part of equipment or appliances can be stained with bright red liquid pigment to play a warning role. When the upper protection plate is not damaged and the protection plate is excavated to the position of the lower protection plate, the bright protection plate and the warning words on the bright protection plate can also play a warning role. In addition, the upper and lower protection plates are connected by wedge-shaped buckling, so that the operation is simple and easy, other additional mounting tools are not needed, and the outdoor operation is suitable.
Furthermore, the thermoplastic plastic has higher impact resistance, and the impact strength of the double gaps of the simply supported beam is more than or equal to 100kJ/m2。
Furthermore, the lower protective plate and the lower protective plate are made of thermoplastic plastic plates, so that the device is light in material and has the density of less than or equal to 0.98g/cm3Easy to carry and install.
Furthermore, the liquid fuel is filled on site, the filling hole is sealed through the conical plug after the filling is finished, and the whole process is simple to operate and easy to operate.
The buried pipeline protection plate is simple in installation method and easy to realize, and when the buried pipeline is mechanically excavated or artificially excavated by external force in a normal operation period, three possibilities exist: 1) when the underground pipeline is excavated from the ground, the underground pipeline is contacted with the upper protection plate, and the excavating device is blocked from further excavation by the upper protection plate 4 made of the ultrahigh molecular weight polyethylene material with high impact property, so that the underground pipeline is protected; 2) directly excavating to the upper protection plate, wherein the bright yellow upper protection plate is exposed outside the soil, and the warning words outside the upper protection plate play a warning role to prevent the continuous excavation; 3) if the destructive power is larger, the excavation device can be stained with red liquid pigment to play a warning role by penetrating the upper protective plate in the excavation process. By means of the countermeasures which can be possibly generated, the buried pipeline can be protected. The complete set of buried pipeline protection plate does not need signal feedback, current pulse and other processes, on one hand, the protection effect cannot be influenced by accidents in the implementation process, and on the other hand, the device is low in manufacturing cost and is beneficial to popularization and application.
