The well cover anti-settlement structure adopts a perimeter reinforced design, including a buffer mechanism and a reinforcement mechanism. The buffer mechanism uses a buffer pad and a buffer spring to reduce shock and a limiting device to prevent the well cover from shifting. The reinforcement mechanism uses a multi-layer reinforced concrete composite structure and a three-dimensional reinforcement mesh for multi-layer filling and reinforcement to reduce stress transmission and settlement.
It effectively reduces vibration and noise of manhole covers, prevents manhole covers from shifting, achieves a long-lasting reinforcement effect, and ensures the stability of the area around the manhole and the smoothness of the road.

Abstract
Description
Technical Field

[0047] Reference Figures 1 to 5 The present invention provides a further description of an embodiment of a well cover anti-settlement structure with reinforced perimeter.
[0048] A manhole cover 8 reinforced around the manhole surface for preventing settlement includes a manhole base 1 and a manhole body 2, and further includes: a manhole cover 8, disposed on the manhole body 2 for sealing the manhole body 2; a buffer mechanism disposed within the manhole base 1 for buffering; and a reinforcement mechanism disposed within the manhole base 1 for reinforcing the area around the manhole body 2, the reinforcement mechanism including: a reinforcement layer 3 disposed within the manhole base 1 for reinforcement; multiple reinforcing bars 4 disposed within the reinforcement layer 3 for reinforcement; a transition layer 5 disposed within the manhole base 1 for reducing stress transmission; a diffusion layer 6 disposed within the manhole base 1 for diffusing force; and a three-dimensional reinforcement mesh 7 disposed on the reinforcement layer 3 for reinforcement.
[0049] refer to Figure 1 and Figure 2In a preferred embodiment, the buffer mechanism includes: a buffer device disposed within the well base 1 for buffering operations; and a limiting device disposed within the three-dimensional reinforcement mesh 7 for limiting operations.
[0050] refer to Figure 2 and Figure 4 In a preferred embodiment, the buffer device includes: a buffer pad 9 disposed on the reinforcing layer 3 and fixedly connected to the reinforcing layer 3; a plurality of mounting grooves 10 disposed within the buffer pad 9 and fixedly connected to the buffer pad 9; and a plurality of buffer springs 11 disposed within the mounting grooves 10 and fixedly connected to the mounting grooves 10.
[0051] refer to Figure 3 and Figure 5 In a preferred embodiment, the limiting device includes: a mounting part having multiple mounting parts disposed within the three-dimensional reinforcing mesh 7 for component installation; and a limiting part having multiple limiting parts disposed within the mounting part for limiting operation.
[0052] refer to Figure 2 and Figure 5 In a preferred embodiment, the mounting part includes: a support column 12 disposed within the three-dimensional reinforcement mesh 7 and fixedly connected to the three-dimensional reinforcement mesh 7; and a sliding groove 13 disposed within the support column 12 and fixedly connected to the support column 12.
[0053] refer to Figure 5 In a preferred embodiment, the limiting part includes: a return spring 14 disposed in the sliding groove 13 and fixedly connected to the sliding groove 13; a sliding column 15 disposed on the return spring 14 and fixedly connected to the return spring 14; a limiting plate 16 disposed on the sliding column 15 and fixedly connected to the sliding column 15; and a limiting groove 17 disposed on the well cover 8 for fixing the limiting plate 16.
[0054] In this configuration, the three-dimensional reinforcement mesh 7 adopts a double-layer reinforced concrete composite structure, which can effectively support the manhole cover 8 and reinforce the area around the manhole body 2. The reinforcement layer 3 and the reinforcing steel bars 4 work together to fill the manhole body 2 with reinforced concrete, effectively reinforcing the manhole body 2. The transition layer 5 is filled with foamed concrete to absorb minor settlement of the base layer and reduce stress transmission. The diffusion layer 6 is made of steel fiber concrete and is flush with the road structure layer to form a load diffusion interface. Through the three-layer filling, the area around the manhole body 2 is effectively reinforced.
[0055] This device, by incorporating a buffer mechanism, effectively dampens and cushions the manhole cover 8 when a vehicle passes over it, reducing force and noise. It also resets the manhole cover 8 to prevent it from shifting. Furthermore, by including a reinforcement mechanism, the device effectively reinforces the manhole body 2 by filling multiple layers of material around it during installation, and further reinforces the contact points with the manhole cover 8 to prevent settlement.
[0056] Working Principle: During installation, this device reinforces the manhole body 2 by filling multiple layers. First, a reinforcement layer 3 is filled, containing reinforcing steel bars 4 for reinforced concrete filling and reinforcement. Then, a transition layer 5 is filled, using foamed concrete to absorb minor settlement of the base layer and reduce stress transmission. Next, a diffusion layer 6 is filled, using steel fiber reinforced concrete and flush with the road structure layer to form a load diffusion interface. Then, a three-dimensional reinforcement mesh 7 is placed on the reinforcement layer 3 and filled with concrete for effective reinforcement. Finally, the manhole cover 8 is fixed to the filled three-dimensional reinforcement mesh 7. During installation, the limiting groove 17 is aligned with the limiting plate 16 for fixation. When a vehicle passes over the manhole cover 8, the buffer pad 9 and buffer spring 11 provide cushioning to reduce force and noise. The return spring 14 and sliding column 15 support and fix the manhole cover 8, ensuring that the manhole cover 8 can return to its original position and will not shift for a long time.
