Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-7, the present invention provides an embodiment: the utility model provides a slip casting drilling hole sealing device, including sealing the PVC pipe, PVC pipe 1, PVC slip casting floral tube 4, expansion rubber ring 6 and bearing ring 7, seal the PVC pipe and be formed by PVC slip casting floral tube 4 and PVC pipe 1 equipment, and the equidimension such as size and slip casting floral tube commonly used after the equipment, be equipped with bearing ring 7 between PVC slip casting floral tube 4 and the PVC pipe 1, the cover is equipped with expansion rubber ring 6 on PVC pipe 1, and expansion rubber ring 6 is located the top of bearing ring 7, seal the PVC pipe and transfer 3 middle parts of drilling.

Through PVC slip casting floral tube 4 for injecting cement into drilling 3, through bearing ring 7 for bearing sealing cement 2, through inflation rubber ring 6 for sealing.
