The manhole base is a circular structure and is fixed at the upper end of the working manhole. The upper and lower parts of the inner side of the manhole base are respectively provided with locking flanges, and the locking flanges of the upper and lower parts are stepped. The two manhole covers are respectively locked above the upper and lower locking flanges. The working manhole is located below the manhole base and is detachably connected to the fall protection net.

[0006] As a preferred installation structure for a double-layer anti-theft manhole cover, the bottom of the outer wall of the manhole base is provided with an outer edge, and a plurality of first fixing holes are evenly distributed on the outer edge. The manhole base is fixedly connected to the upper end of the working well by passing an L-shaped steel bar through the first fixing holes.

[0007] As a preferred installation structure for a double-layer anti-theft manhole cover, multiple reinforcing ribs are distributed between the outer wall and the outer edge of the manhole base.

[0008] As a preferred installation structure for double-layer anti-theft manhole covers, the outer surface of the manhole base has a frustum-shaped structure.

[0009] As a preferred installation structure for a double-layer anti-theft manhole cover, the working well has multiple expansion bolts evenly distributed on its inner wall below the manhole base, and the outer periphery of the anti-fall net is connected to each of the expansion bolts by safety buckles.

[0010] As a preferred installation structure for a double-layer anti-theft manhole cover, the manhole cover has multiple second fixing holes distributed around its outer periphery, and multiple threaded holes corresponding to the second fixing holes are distributed above the clamping edge. The manhole cover is fixedly connected to the threaded holes of the clamping edge by screws.

[0011] The beneficial effects of this utility model are as follows: The installation structure of the double-layer anti-theft manhole cover proposed in this utility model uses a double-edge structure with a stepped shape at the top and bottom to install the double-layer manhole cover. The overall structure is simple, stable and easy to install. At the same time, it can also be detachably connected with an anti-fall net, which works in conjunction with the double-layer manhole cover to play a multiple anti-fall role, making it safer and more reliable.

[0019] Reference Figure 1-2An embodiment of this utility model provides an installation structure for a double-layer anti-theft manhole cover, including: a manhole base 1, a manhole cover 2, and an anti-fall net 3. The manhole base 1 is a circular structure and is fixed at the upper end of the working manhole. The upper and lower parts of the inner side of the manhole base 1 are respectively provided with locking edges 4, and the locking edges 4 are stepped between the upper and lower parts. The two manhole covers 2 are respectively locked above the upper and lower locking edges 4. The working manhole is located below the manhole base 1 and is detachably connected to the anti-fall net 3.

[0020] In the above technical solution, a double-edge structure with stepped upper and lower sections 4 is used to install the double-layer manhole cover 2. The overall structure is simple, stable, and easy to install. At the same time, a fall-prevention net 3 can be detached and connected to it. In conjunction with the double-layer manhole cover 2, it plays a multiple role in preventing falls, making it safer and more reliable.

[0021] In some embodiments, the bottom of the outer wall of the well base 1 is provided with an outer edge 5, and a plurality of first fixing holes are evenly distributed on the outer edge 5. The well base 1 is fixedly connected to the upper port of the working well by passing an L-shaped steel bar 6 through the first fixing holes. This structural design allows the well base 1 to be stably connected to the upper port of the working well, and the structure is simple and easy to install.

[0022] Furthermore, multiple reinforcing ribs 7 are distributed between the outer wall and the outer edge 5 of the well base 1. The reinforcing ribs 7 serve to increase the overall strength of the well base 1, ensuring the structural stability of the outer edge 5 and preventing damage or loosening.

[0023] In some embodiments, the outer surface of the well base 1 has a frustum-shaped structure. This structural design makes the overall strength of the well base 1 superior and its placement and installation more stable.

[0024] In some embodiments, the inner wall of the working well located below the well base 1 has a plurality of expansion bolts 8 evenly distributed, and the outer periphery of the fall arrestor net 3 is connected to each of the expansion bolts 8 by safety buckles 9. This structural design makes the installation and disassembly of the fall arrestor net 3 more convenient, facilitating maintenance and replacement by staff.

[0025] In some embodiments, the manhole cover 2 has a plurality of second fixing holes distributed on its outer periphery, and the retaining edge 4 has a plurality of threaded holes corresponding to the second fixing holes distributed above it. The manhole cover 2 is fixedly connected to the threaded holes of the retaining edge 4 by screws. This structural design can further improve the connection stability of the manhole cover 2, prevent loosening, and facilitate installation and disassembly.
