The prefabricated cover board 2 is hollow circular ring shape structure, that is to say, that 2 inside of the prefabricated cover board is absolutely empty in defining one
Between, the hollow space is implemented as annular shape, and the size of the annular shape is according to the inspection shaft and the prefabricated pit shaft 1
Change and changes, in one embodiment of this invention, a diameter of 500mm of the hollow space, the model of the prefabricated pit shaft 1
For DN700.
When the prefabricated cover board 2 is set to the prefabricated pit shaft 1, the hollow space penetrates through cylinder well space,
And cylinder well space described in unicom and roadbed environment above.In one embodiment of this invention, the opening of the prefabricated cover board 2
Area is not more than the opening area of the prefabricated pit shaft 1, and the prefabricated cover board 2 and the prefabricated pit shaft 1 are symmetrical
Structure is symmetrical arranged along a central axes.
Interim well lid is anti-bias：The interim well lid anti-bias structure center is disposed through facing on the prefabricated well lid 6
When well lid, control fastener 3 to strut auxiliary connecting rod 9, wherein inner wall of the auxiliary connecting rod 9 against the prefabricated pit shaft 1.
Specifically, an interim well lid 2 by center symmetric setting on the prefabricated well lid 6, wherein the interim well lid 2
Upper formation prefabricated hole, wherein the prefabricated hole is arranged centered on the center of the interim well lid 2.That is, described
Interim well lid 2 is also implemented as a hollow circular ring structure, and the prefabricated hole is its hollow structure.It is worth noting that, working as institute
When stating interim well lid 2 and being placed on the prefabricated well lid 6, the central axes of the interim well lid 2 and the prefabricated hole coincide with
The central axes of the prefabricated well lid 6, in an embodiment of the present invention, the size of the reserving hole is 50mm.
The interim well lid anti-bias structure includes fastener 3, and push rod 4, mobile jib 8, elastic element 5 and at least one auxiliary connect
Bar 9, wherein the push rod 4 and the elastic element 5 are placed in the mobile jib 8, the auxiliary connecting rod 9 is connected to the mobile jib
9 other end, and symmetrically distributed around centered on the mobile jib 9, one end of the elastic element 5 is connected to the push rod
4, the other end is connected to the auxiliary connecting rod 9, and the auxiliary connecting rod 9 forms secondary surface after strutting.
Specifically, the elastic element 5 is set to the mobile jib 8, and described in one end connection of the elastic element 5
4 other end of push rod connects the auxiliary connecting rod 9, and when the push rod 4 is far from the mobile jib 8, the elastic element 5 is in nature
State, at this point, the auxiliary connecting rod 9 is shunk close to the mobile jib 8, two when the push rod 4 is close to the mobile jib 8, the bullet
Property element 5 by the push rod 4 push and be extruded, the auxiliary connecting rod 9 is opened around centered on the mobile jib 8.
In addition, the fastener 3 is set to one end of the push rod 4, the size of the push rod 4 is matched with the pre-manufactured hole
Hole, so that the push rod 4 may pass through the interim well lid 2, and the fastener 3 is set on the push rod 4 with tight
Gu the push rod 4 and the interim well lid 2, in an embodiment of the present invention, the fastener 3 are a bolt.In addition, passing through
Screwing on the fastener 3 can push the push rod 4 to strut the auxiliary connecting rod 9, anti-bias to play the role of interim well.
In summary, the mobile jib 5 passes through the prefabricated hole and passes through the fastener 3 and the interim well lid 2
Connection, since the central axes of the prefabricated hole coincide with the central axes of the prefabricated pit shaft 1, the also position of the described therefore described mobile jib 8
In on the central axes, screwing the fastener 3 to push the push rod 4, the work that the push rod 4 passes through the elastic element 5
It is anti-to play interim well lid 2 with strutting the auxiliary connecting rod 9 until the auxiliary connecting rod 9 is against the inner wall of the prefabricated pit shaft 1
Inclined effect improves structural strength, and in an embodiment of the present invention, the supporting surface that the auxiliary connecting rod 9 is formed is a diameter of
700mm。
