Various public infrastructure construction supporting urban life falls into the category of municipal engineering, such as common urban roads, bridges, subways, and various pipelines closely related to life: rainwater, sewage, water supply, recycled water, electricity (part outside the red line), telecommunications, heat, gas, etc. There are also squares, urban greening, etc. Manhole covers are used to cover roads or deep wells in homes to prevent people or objects from falling. According to the material, they can be divided into metal manhole covers, high-strength fiber cement concrete manhole covers, resin manhole covers, etc. Manhole covers are mostly circular and are used for green belts, sidewalks, motor vehicle lanes, docks, alleys, etc.
[0003] Most of the manhole covers used in municipal projects in cities are not only easy to shift during use, causing damage to vehicles and injuries to pedestrians, but are also easy to be stolen. After being stolen or shifted, the exposed manhole covers are easy to cause damage to vehicles and injuries to pedestrians. Utility Model Content

[0016] The beneficial effect of this improvement is: when filter cartridge 1 and filter cartridge 2 are installed under the manhole cover, the cross block will be engaged with rotating rod 1. When the manhole cover is detached from the top of the well body, the rotating rod can be rotated to drive the gear to rotate. At this time, the sliding rods engaged with the gear on both sides will cause the extrusion block to squeeze the block 1. At this time, the block 1 will slide to the telescopic chamber 1, and the mounting seat can be detached from the bottom of the manhole cover, thereby removing the filter cartridge 1 and filter cartridge 2 from the bottom of the manhole cover.
