[0018] It should also be further understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0019] In the embodiments shown in the accompanying drawings, the directional indications (such as up, down, left, right, front, and back) used to explain the structure and movement of the various components of this invention are relative rather than absolute. These descriptions are appropriate when these components are in the positions shown in the drawings. If the descriptions of the positions of these components change, these directional indications also change accordingly.

[0020] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0021] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0022] Please see Figure 1 and combined Figure 2 , Figure 3 and Figure 4 As shown in the figure, this utility model provides a high-load-bearing anti-settlement manhole cover structure for construction, mainly used in municipal and building construction sites. It has high load-bearing capacity, anti-settlement properties, and good sealing performance. The structure includes a base, an inner cover, and a top cover. The components are tightly fitted together through a reasonable structural design, effectively preventing debris from entering and manhole cover settlement.

[0023] The high load-bearing anti-settlement manhole cover structure includes a base 1, an inner cover 2, and a top cover 3. The base 1 is an integral support component, usually made of high-strength cast iron or composite materials to ensure sufficient structural strength.

[0024] The base 1 of this utility model has a mounting hole 11 in the middle for accommodating the inner cover 2 and the top cover 3.

[0025] Specifically, an annular bearing edge 12 is provided on the inner edge surface of the mounting hole 11 to support the top cover 3. An annular stepped edge 13 is also provided on the bottom inner edge surface of the mounting hole 11, which is located below the bearing edge 12 and is used to support the inner cover 2.

[0026] In this invention, two opposing limiting flanges 14 are integrally formed on the inner edge surface of the mounting hole between the stepped edge 13 and the bearing edge 12. Preferably, the limiting flanges 14 in this invention have a wedge-shaped block structure.

[0027] Specifically, the inner cover 2 of this utility model is fitted into the mounting hole 11 of the base 1, specifically located in the space between the stepped edge 13 and the bearing edge 12. A wedge-shaped check flange 21 is provided on the top outer edge of the inner cover 2. During installation, the inner cover 2 is inserted into the mounting hole 11 from bottom to top, and by rotating it at a certain angle, the check flange 21 is misaligned and engaged with the limiting flange 14, thereby achieving the limiting and fixing of the inner cover 2 and preventing it from falling off or loosening. Please refer to [link to relevant documentation]. Figure 5 and Figure 6 As shown.

[0028] It should be further noted that the present invention also provides a slot on the outer edge of the inner cover 2 to accommodate the inner cover 2 when it is inserted into the space between the stepped edge 13 and the bearing edge 12, so as to avoid interference with the limiting flange 14.

[0029] The top cover 3 of this utility model is installed on the bearing edge 12 of the base 1, serving as the outermost cover plate and directly bearing the load of vehicles and pedestrians. The contact surface between the top cover 3 and the bearing edge 12 is preferably machined to ensure flatness and tightness.

[0030] To further improve the stability and functionality of the structure, the present invention may also adopt the following preferred embodiments: A fixing hole 31 is provided in the center of the top cover 3, and a protrusion 22 is formed by the center of the inner cover 2 protruding upward, with a through hole 23 provided on the protrusion 22. During installation, the fixing hole 31 is aligned with the through hole 23, and a bolt 4 is inserted and locked in place. This design makes the top cover 3 and the inner cover 2 integrated, which not only facilitates installation but also enhances the overall integrity and prevents the components from shifting.

[0031] This invention features multiple filter holes 32 on the top cover 3 for ventilation and heat dissipation, preventing the accumulation of heat or air pressure inside the well. Additionally, ribs 33 are provided on the inner side (bottom surface) of the top cover 3 to improve its rigidity and load-bearing capacity, extending its service life.

[0032] This utility model features a sealing ring 5 on the bearing edge 12, with the top cover 3 pressed onto the sealing ring 5 by bolt tightening, achieving a waterproof seal. The sealing ring 5 can be installed in two ways: firstly, directly embedded in the upper surface of the bearing edge 12 (e.g., ...). Figure 7 (As shown); secondly, it is located at the corner where the bearing edge 12 connects to the side wall of the mounting hole 11, and its cross-section is L-shaped (as shown). Figure 8 As shown in the figure, this method can achieve sealing of both the end face and the side, resulting in better watertightness.

[0033] Multiple mounting lugs 15 extend outward from the bottom outer edge of the base 1, and locking holes 16 are provided on the mounting lugs 15. During construction, the base 1 is fixed to the wellhead base by detachably inserting expansion bolts 6 into the locking holes 16. This design distributes the load and effectively prevents the well cover from settling.

[0034] A reinforcing rib 17 is also provided between the mounting ear plate 15 and the outer edge of the base 1 to further improve the overall rigidity and compressive strength of the base.

[0035] During installation, first, fix the base 1 to the pre-set base at the wellhead using expansion bolts 6 to ensure stable installation; then place the sealing ring 5 at the predetermined position on the bearing flange 12; then insert the inner cover 2 into the mounting hole 11 of the base from bottom to top, and rotate the inner cover 2 so that its check flange 21 engages with the limiting flange 14; next, place the top cover 3 on the bearing flange 12 and align the fixing hole 31 of the top cover with the through hole 23 of the inner cover; finally, insert and lock the bolts 4.

[0036] This manhole cover structure achieves high load-bearing capacity, anti-settlement, and good sealing through multiple structural designs, making it particularly suitable for complex working conditions such as construction sites.

[0037] Finally, the method described in this application is merely a preferred embodiment and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
