Preferably, the connecting column 201 is "convex" shaped structure, the top end part of the "convex" shaped structure and end portion
Junction is equipped with chamfering structure, and second screw hole 202 is set to the top end part of "convex" shaped structure, it can be seen that, Neng Gouzeng
Add the structural stability of connecting column 201, it is not easy to break, well lid 100 and draining 200 connective stability of cage are improved to realize.
Preferably, the overflow launder 204 is semicircular structure, drained convenient for draining cage 200.
Preferably, the boss 104 includes fixing seat and erecting bed, the area of the fixing seat and erecting bed is 1/
The area of a circle, the fixing seat diameter base size are greater than fixing seat top diameter size, the fixing seat top diameter ruler
Very little equal with the erecting bed diameter dimension, the fixing seat side wall is domatic structure, and the fixing seat and erecting bed are overall
Vertical direction and be intended for well lid second end face 100b edge direction be planar structure, therefore, convenient in the first screw hole 105
Screw thread process, while preventing the first bolt 400 during the installation process by 100 capping of well lid, it avoids influencing using or even causes to pacify
Full hidden danger.
Preferably, the diameter dimension that the mark post hole 101 is located at first end face 100a, which is less than mark post hole 101, is located at well lid
The diameter dimension of second end face 100b, the mark post hole 101 are located in more of the position rib 106a of well lid second end face 100b
The heart intersects place, it can be seen that, it is convenient for well lid draining when a small amount of ponding to use, meanwhile, the intensity of well lid 100 is not influenced.
Preferably, height is higher than two end heights, the top rib 106a at the center of the every rib 106a
End is arc-shaped structure, and therefore, according to amechanical angle, rib 106a has more protection to well lid 100, prevents well lid 100
Fragmentation prevents the deformation of well lid 100, fragmentation when road vehicles traveling presses through well lid.
Preferably, the card slot 205 can be equipped with multiple and be arranged from top to bottom along the drainage hole 203, it is adjacent
The third drainage hole 203c for importing the second bolt 500 is equipped between the card slot 205, it therefore, can be convenient for adjusting well lid
100 raising height, suitable for being suitable under different road conditions.
Preferably, being equipped with helicitic texture in the mark post hole 101, the installation of mark rod can be convenient for.
Preferably, the bar 312 is coated with reflectorised paint, after well lid 100 is detached from, night can remind pedestrian and Che
, avoid pedestrian and vehicle from falling into well.
Preferably, first bolt 400 and the second bolt 500 using surface zincincation or use stainless steel material
It is made, therefore, can be improved weatherability and corrosion resistance, convenient for the later maintenance of well lid.
The reserved and reserved depth of pit shaft, is slightly less than the height of fixed pedestal 300 by installation process, and the diameter for reserving pit shaft is big
In 300 largest contours diameter of fixed pedestal, the third screw hole 331 in 330 outside of mounting cylinder is wrapped up by adhesive tape, prevents concrete
Enter in third screw hole 331 when pouring, fixed pedestal 300 is placed in pit shaft, by concrete to 300 bottom of fixed pedestal
It is irrigated landfill with surrounding, while adjusting the position of fixed pedestal 300, realizes that it is fixed after concrete setting, therefore can
Reinforce pit shaft intensity, caves in after avoiding pit shaft from being immersed in water；Draining cage 200 is fixed on 100 bottom of well lid by the first bolt 400
Portion, then draining 200 low side of cage is put into mounting cylinder 330 and makes the corresponding third screw hole 331 of drainage hole 203, then by special
Second bolt 500 is passed through drainage hole 203 and screwed in third screw hole 331 by industry spanner, and putting down well lid 100 keeps draining cage 200 complete
Enter in mounting cylinder 330 entirely, to realize that well lid 100 is fixed on 300 top of fixed pedestal.
Use process can be used as common well lid use, pass through the fixed form and fixation of fixed pedestal 300 after integral installation
The height of pedestal 300 can increase the entire compression ability of well lid, avoid pit shaft landslide deformation；When surface gathered water is excessive or pit shaft
When outer spray occurs for internal water accumulation, well lid 100 can be lifted up extreme position by mounting hole 102, then rotary well cover 100 arrives
Extreme position makes the second bolt 500 be placed in 205 bottom of card slot, and the second bolt 500 is made to be placed in card slot 205 after well lid 100 is put down
It is interior, realize the space generated between well lid 100 and fixed pedestal 300 for draining, ponding is discharged or is discharged by drainage hole 203
Therefore pit shaft can prevent pedestrian or vehicle from falling into well, and can be avoided that well lid is washed away to be caused while draining
Pit shaft exposure.
