Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5 and Fig. 6, the utility model includes well lid mounting seat 4, the and of outer layer well lid 1
Internal layer well lid 2.
Well lid mounting seat 4 is provided with three-level ladder well head, subordinate rank of the support of internal layer well lid 2 installed in three-level ladder well head
On tread, outer layer well lid 1 supports on the intermediate cascaded surface of the upper surface of internal layer well lid 2 and three-level ladder well head simultaneously.
Outer layer well lid 1 is directed by the object rolled, and internal layer well lid 2 uses the longevity under the protection of outer layer well lid 1, with longer
Life, before finding that outer layer well lid 1 damages, cause well head exposes to come because well lid damages without worry.
Between the side wall of outer layer well lid 1 and three-level ladder well head, the intermediate cascaded surface of outer layer well lid 1 and three-level ladder well head
