[0038] It is not difficult to find that a plug-in interface is provided on the right side of the locking disk 403, and a threaded ring matching the thread line is provided on the inner side of the plug-in interface.

[0040] It should be explained that the outer sides of the sleeve 1 and the movable cylinder 3 are provided with plug-in holes that penetrate into the inner sides thereof. The provision of multiple plug-in holes is conducive to adjusting the sleeve 1 and the movable cylinder 3, thereby facilitating the improvement of the overall flexibility of use. The plug-in column 402 is plugged into the sleeve 1 and the movable cylinder 3 through the plug-in holes, and the connecting plate 401, the connecting plate 404 and the bonding plate 405 are all bonded to the outer side of the sleeve 1.

[0041] In this embodiment, the connection between the plug-in column 402, the sleeve 1 and the movable cylinder 3 is conducive to the adjustment of the top support assembly. At the same time, the threaded connection of the locking plate 403 is conducive to improving the stability of the plug-in column 402. The bonding effect of the connecting plate 404 and the bonding plate 405 further improves the overall stability of use.

[0042] See also Figure 5 In order to improve the stability of the structure, the stabilizing component 6 in this embodiment includes an outer ring 601, an extension column 602 and a plug-in board 603. The outer ring 601 is fixed to the outer side of the movable cylinder 3, and the back side of the extension column 602 is fixed to the outer ring 601.

[0043] It is also necessary to explain that the provision of the extension column 602 facilitates the adjustment of the plug-in board 603 , and further facilitates the clamping and fixing of the cover plate body 5 through the plug-in board 603 .

[0044] It needs to be elaborated that the front side of the extension column 602 is fixed to the plug-in board 603, and the extension column 602 includes a fixed column and a movable column, the fixed column is fixed to the front side of the outer ring 601, and the movable column is movably connected to the fixed outer side, the front side of the movable column is fixed to the plug-in board 603, and the plug-in board 603 is movably connected to the cover plate body 5.

[0045] In this embodiment, after the plug-in plate 603 is inserted into the clamping ring groove through the telescopic effect of the extension column 602, the top of the top support assembly and the cover plate body 5 are further stabilized, preventing the movable tube 3 from moving away in the installation groove, which is beneficial to the stability of the structure.

[0046] See also Figures 6 to 7In order to improve the safety of the structure, the anti-sinking component 2 in this embodiment includes a rotating shaft 201, a swinging plate 202, a fixed plate 203, a movable block 204, a connecting platform 205 and an acting component. The rotating shaft 201 is rotatably connected to the outer wall of the sleeve 1. The rotating connection setting is conducive to controlling the fixed plate 203 by adjusting the angle of the swinging plate 202. The side of the rotating shaft 201 away from the sleeve 1 is fixed to the swinging plate 202, and the fixed plate 203 is fixed to the side away from the swinging plate 202. The movable block 204 is hinged to the side of the fixed plate 203 away from the rotating shaft 201. The hinged setting is conducive to the stability of the downward pressure of the fixed plate 203, the transmission of the downward force, and thus the stability of the overall use. The movable block 204 is movably connected to the top of the connecting platform 205, and the bottom of the connecting platform 205 is fixed to the acting component.

[0047] It is also necessary to elaborate that, by the lifting force on the swing plate 202 when sinking, the fixed plate 203 is adjusted under the rotation of the rotating shaft 201, so that the force is transmitted to the acting component through the connecting platform 205, which is conducive to the stable use of the overall component.

[0048] It is not difficult to see that the action component includes an action block 206, a receiving plate 207 and an action plate 208. The action block 206 is fixed to the bottom of the connecting platform 205, and the receiving plate 207 is fixed to the action plate 208 on the side away from the action block 206. The action plate 208 is movably connected to the outer wall of the sleeve 1, and a stabilizing slide groove is provided on the top of the connecting platform 205.

[0049] In addition, the provision of a stable slide groove is beneficial to the stability of the displacement of the movable block 204, which is beneficial to the stable swing of the fixed plate 203, thereby facilitating the stable transmission of the downward force and improving the stability of the overall assembly.

[0050] The movable block 204 is slidably connected to the stable slide groove, the action block 206 is a four-sided pyramid structure with a wide top and a narrow bottom, and the top of the receiving plate 207 is in contact with the outer side of the action block 206.

[0051] Moreover, the four-sided pyramid structure facilitates the downward movement of the action block 206 to push the receiving plate 207 to both sides, thereby facilitating the outward extension of the action plate 208, thereby realizing the anti-sinking function.

[0052] In this embodiment, the swing plate 202 is adjusted after sinking, so that the connecting platform 205 is subjected to downward pressure, and then through the structural action of the action block 206, the receiving plate 207 drives the action plate 208 to extend to both sides, which is beneficial to increase the contact area at the bottom of the sleeve 1, thereby facilitating the improvement of the supporting force of the overall structure, preventing sinking, and thus contributing to the realization of the anti-sinking function.

[0053] In addition, a construction method of a cover plate protection structure is now proposed, which is applied to the above-mentioned cover plate protection structure, and includes the following steps: 1) After on-site measurement and layout, earth excavation is carried out and the excavated slots are manually cleaned; 2) Determine the bearing capacity and required quantity of sleeve 1 according to the site and pipeline size; 3) Determine the placement position of sleeve 1 and perform preliminary stabilization on sleeve 1; 4) Adjust the movable cylinder 3 inside the sleeve 1 and fix the movable cylinder 3 by the fixing component 6; 5) After the construction of the top support assembly is completed, an anti-seepage geotextile 7 is laid on the upper part of the protection pipeline with the movable tube 3 as the boundary; 6) Confirm the position of the clamping ring groove and the installation groove, and clamp the plug-in board 603 and the movable cylinder 3 with the clamping ring groove and the installation groove in turn, and check the installation and stability of the cover plate body 5; 7) After confirming that the cover plate body 5 is stably placed, backfill the soil and then continue construction on the top surface of the cover plate body 5.

[0054] The working principle of the above embodiment is: (1) According to the location of the pipeline and the on-site conditions, the required sleeve 1 is placed on the ground, and the plug-in column 402 is plugged into the sleeve 1 and the movable cylinder 3 by pulling up the movable cylinder 3. Then the plug-in column 402 is rotated, and the connecting plate 401, the connecting plate 404 and the bonding plate 405 are bonded to the outer side of the sleeve 1 to determine the height of the sleeve 1 and the movable cylinder 3. After ensuring that the connection between the sleeve 1 and the movable cylinder 3 is stable, preliminary backfilling is performed, and the anti-seepage geotextile 7 is covered on the pipeline and located between the movable cylinders 3. Then the cover plate 5 is lowered, and the plug-in plate 603 is stretched outward to The plug-in plate 603 is clamped with the clamping ring groove, and the movable cylinder 3 and the cover plate body 5 are stabilized by the extension effect of the extension column 602. At the same time, the movable cylinder 3 is placed in the installation groove to fix the top support assembly and the cover plate body 5. The compression material setting of the anti-seepage geotextile 7 squeezes the outer side of the movable cylinder 3, thereby further improving the stability between the top support assembly and the cover plate body 5. In this process, the design of the cover plate body 5 is conducive to adjusting the position of the top support assembly, which is conducive to adapting to the needs of various pipeline placement methods and improving the overall convenience of use.

[0055] (2) When the soil changes and the top support assembly collapses, the swing plate 202 swings upward, and the fixed plate 203 is pressed downward by the rotation of the rotating shaft 201. At the same time, the force is transmitted to the action block 206 through the connecting platform 205. Through the structural setting between the action block 206 and the receiving plate 207, when the action block 206 moves downward, the action plate 208 opens to both sides, thereby increasing the contact area between the sleeve 1 and the bottom soil, which is beneficial to prevent the overall collapse and is beneficial to the stability of the overall structure.
