[0053] The protective structure 1 also includes a flexible layer 15 corresponding to at least two supporting protrusions 14. The supporting protrusions 14 act on the pipeline 100 through the corresponding flexible layer 15. The flexible layer 15 can provide good protection for the pipeline 100 and can play a certain vibration absorption role. In conjunction with the supporting protrusions 14, it can ensure stable support for the pipeline 100 while effectively improving the protective effect on the pipeline 100.

The material of the protective structure 1 is concrete material, which is easy to prepare and shape, has low preparation cost, high overall support strength, and can improve the support effect on the pipeline 100.

[0057] In some or certain embodiments, the protective structure 1 may also include a bottom 16 and a top 17, the bottom 16 may be a container-shaped structure with a support groove 161, the bottom 16 may be embedded with steel bars (not shown in the figure), and the top 17 is connected to the bottom 16 and closes the support groove 161 to form a support cavity 11. At least two support protrusions 14 may be provided at the bottom of the support groove 161. This structure is convenient for preparation and also convenient for forming the filling layer 2.

[0062] In some or certain embodiments, the material of the transition cushion layer 18 may be a rough stone grade ash transition cushion layer 18, which is convenient for preparation.

[0063] Based on the same inventive concept, the present application also provides a pipeline protection method, which is implemented using the pipeline protection device as above, wherein the protection structure includes a bottom and a top, wherein the bottom is a container-shaped structure with a support groove, and the top and the bottom are connected and the support groove is closed to form a support cavity. The pipeline protection method includes:

[0064] S101: Detect the location of the buried pipeline.

[0065] S102: Dig a protective trench around the pipeline according to the location of the pipeline.

[0066] S103: Casting to form a sleeve on the bottom of the pipeline.

[0067] S104: forming a filling layer in the support groove at the bottom, which fills the support groove and covers the pipeline.

[0068] S105: forming a top portion, the top portion closing the notch of the supporting groove and forming a supporting cavity.

[0069] The structure of the pipeline protection device and its corresponding technical effects can be referred to above and will not be elaborated here. For pipelines that have been buried and laid underground, and roads need to be laid on the ground corresponding to the buried pipelines, the location of the buried pipelines can be detected first, and then a protection groove can be dug around the pipelines to provide space for the pipeline protection device to form, and then a pipeline protection device that plays a protective role on the pipeline is formed in the protection groove, which can improve the protection effect of the buried pipelines.

[0070] It should be noted that for pipelines that have been determined to need to be laid across roads, a protective trench can be dug at the location where the road needs to be laid, a pipeline protection device can be formed in the protective trench, and the pipeline can then be passed through the pipeline protection device to complete the laying of the pipeline.

[0071] In step S101 of some or certain embodiments, a pipeline detector may be used to determine the location of the pipeline, so as to facilitate the determination of the location of the pipeline that has been buried.

[0072] In step S102 of some or certain embodiments, after the location of the pipeline is determined, a protective trench may be dug around the pipeline by a machine.

[0073] In step S103 of some or certain embodiments, the bottom of the protective structure may be formed by casting, and the material of the protective structure may be concrete for ease of preparation.

[0074] In some or certain embodiments, the bottom of the protective structure may be in the form of a box with one end open. When the bottom of the protective structure is cast, it may be combined with, for example, a plate structure or a steel bar structure, so that a space for concrete pouring can be formed between the plate structure and the protective groove, thereby obtaining the bottom of the protective structure. When the cast protective structure is higher than the pipeline, the protective structure will naturally form a first opening and a second opening that are sleeved on the pipeline. After the bottom of the protective structure is cast, the plate structure can be removed.

[0075] In step S104 of some or certain embodiments, a filling layer is formed in the bottom support groove, which fills the support groove and covers the pipe. The filling layer can be formed by pouring a large amount of gravel into the bottom support groove, and the gravel buries the pipe passing through the support groove and fills the filling layer of the filling groove.

[0076] In some or certain embodiments, the filling layer may be a gravel filling layer. Before step S105, the pipeline protection method may further include:

[0077] Settle the gravel fill layer.

[0078] Sedimentation water can be used to settle the gravel filling layer, which can ensure that the gravel filling layer has a certain compressibility while improving the contact density between the gravels to increase the support effect on the pipeline.

[0079] In some or certain embodiments, after the gravel filling layer is settled, before step S105, the pipeline protection method further includes:

[0080] Compact the gravel filling layer. This can improve the support effect on the pipeline. The gravel filling layer can be compacted by mixing rough stone between the gravel filling layer and the bottom.

[0081] In step S105 in some or certain embodiments, the top may be obtained by pouring concrete.

[0082] In some or certain embodiments, after forming the top, the pipeline protection method may further include:

[0083] The top is backfilled with rough stone graded ash to form a transition cushion, and an installation groove can be left on the transition cushion to facilitate road preparation.

Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine different embodiments or examples described in this specification.

[0085] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.
