STRUCTURE CONSTRUCTING AN ENVIRONMENT TO DIAGNOSE SAFETY OF CONSTRUCTION UNDER WATER

摘要

In the present invention, the lower flange 11 is tightly fixed to the lower index film band 20 on the outer circumferential surface of the pier foundation 1 to be safely diagnosed, and the upper flange 12 is the upper index film band on the outer circumferential surface of the piers 3. A high density transparent index film housing 10 which is tightly fixed to 30 to create a sealed environment in which the safety diagnosis worker can safely diagnose therein; A locking clip (40) coupled to and locked in an opening vertically opened to one side of the high density transparent index film housing (10); A discharge connection jack (50) attached to an outer surface of the high density transparent resin film housing (10) to connect a connection hose (52) of the water pump (51) for discharging the water filled therein; Injecting air connection jack 60 attached to the other side of the high density transparent resin film housing 10 to connect the injection hose 62 of the air injection device 61 to supply air to the safety diagnosis worker therein Characterized in that configured to include. The present invention as described above is to create an environment that can diagnose the scour state of the underwater structure in the non-underwater environment for the operator diagnosing the scour state of the outer wall of the bridge foundation underwater structure.
