The plate consists of a plurality of annular plates with sequentially increasing diameters, and the corresponding number of annular plates can be selected according to the size of the pits during installation; the annular plate is foldable, so that the volume is reduced, and the transportation is convenient.

for shallower, larger-mouth pits: a first auxiliary mounting plate with a first notch group and a second notch group is adopted, the first support column group is clamped in the first notch group, the second support column group is clamped in the second notch group, and the screw is rotated to enable the first support column group to be supported on the side wall of a pit hole, and the second support column group to be vertically supported on the bottom of the pit hole; the double support formed by the first support column group and the second support column group can provide stronger support force.

For unhardened pit sidewalls (e.g., earth pits): the supporting leg adopts a supporting leg with an acute angle or a raised cambered surface at the bottom; the support feet can be inserted into the side walls of the (soil) pits to form stable supports.

For hardened pit sidewalls (e.g., cement hardened manhole): the supporting legs adopt rubber wheels which are eccentrically arranged. When the support device is installed, the center of the rubber wheel is close to the side wall of the pit and forms a support (the rubber wheel eccentrically arranged naturally sags), when the support device is subjected to pressure from the upper part in reuse, the rubber wheel is forced to slightly rotate, the center of the rubber wheel is slightly far away from the side wall of the pit, so that the whole support radius of the support device is increased, the friction force between the rubber wheel and the side wall of the pit is increased, and the support effect is enhanced; the process is reversible, which is beneficial for the support device to adapt to vibration or fluctuation caused when the vehicle passes over the panel.

It should be noted that, the supporting device may be loosened due to vibration or heave caused by the vehicle or the like driving over, the covering device is not suitable to be directly and fixedly connected with the supporting device, otherwise, the covering device may transmit the rebound upward force to the supporting device, so that the loosening is caused. The covering device can be fixed with the ground by using ground nails and the like so as to avoid displacement when a vehicle runs through.

Although embodiments of the present invention have been disclosed above, it is not limited to the details and embodiments shown, it is well suited to various fields of use for which the invention is suited, and further modifications may be readily made by one skilled in the art, and the invention is therefore not to be limited to the particular details and examples shown and described herein, without departing from the general concepts defined by the claims and the equivalents thereof.
