Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.
Referring to figs. 1 and 2, the pavement Manhole cover assembly for schematically showing the utility model, including hollow
Bearing frame 1 and the well lid pallet 2 for being embedded at bearing frame 1.The reinforcing rib 3 of domed structure, reinforcing rib are equipped in well lid pallet 2
3 both ends are connected to the two sides of the bottom wall of well lid pallet 2, and the top of reinforcing rib 3 towards well lid pallet 2 is arched upward, to prevent well
The depression in centre deformation of covered tray 2.The first finish coat 21, the first cement sand bed are successively arranged in well lid pallet 2 from top to bottom
22 and pea gravel concreten layer 23, reinforcing rib 3 be located in pea gravel concreten layer 23, the road surface of the first finish coat 21 and hoistway mouth surrounding
Mat formation and be consistent, the first cement sand bed 22 is for levelling, and pea gravel concreten is since its density is higher, and microlith is mixed
Solidifying soil is higher with the being tightly combined property of reinforcing rib 3, further improves the rigidity of the well lid pallet 2.
The deep floor 24 perpendicular with it is additionally provided on the bottom wall of well lid pallet 2, the top of deep floor 24 is connected to
Reinforcing rib 3, deep floor 24 increase the tie point of well lid pallet 2 and reinforcing rib 3.Reinforcing rib 3 includes the first rib 31 and the
Two ribs 32, the first rib 31 and the second rib 32 are perpendicular, it is to be understood that the number of the first rib 31 and the second rib 32
