The utility model relates to a local blind stifled shutoff body of underground high water head hole room crowd's concrete belongs to the local blind stifled shutoff body structure of underground cavern crowd's concrete. The hole room both ends that need the shutoff are the interim shutoff of the long tube bag mould bag concrete body no. 1 and the interim shutoff of the long tube bag mould bag concrete body no. 2, are the permanent shutoff of the underwater concrete bodies in the middle of these two the interim shutoff of long tube bag mould bag concrete bodies. The advantage is: novel structure realizes forming local shutoff body structure more than the surface of water, has avoided the personal safety hidden danger that the diving operation brought, the construction is quick, convenient, shortens the construction progress, the mould bag forms the local shutoff body after filling the concrete, and it is great that the local shutoff body has the plastic deformation ability, can adapt to the hole room section of various complicacies, the interim shutoff body is unanimous with permanent shutoff concrete material, without the form removal, has simplified construction procedure.
