DEVICE FOR TEMPORARY FILLING OF HOLES AND CRACKS IN STIFF STRUCTURES OF ANY SHAPE AND CONFIGURATION, WHICH ARE FILLED WITH LIQUID Russian patent published in 2015 - IPC F16L55/168 F16L55/18 B63B43/16 

FIELD: construction.

SUBSTANCE: invention proposes a device for temporary filling of holes and cracks in stiff structures filled with liquid, which includes a load-carrying platform with a central axial hole, in which a thrust screw with a rotation handle is arranged on one end face and with a sealing gasket on the other end, assemblies for attachment of the device on the surface being repaired with control elements by pressing and separation. The assembly for attachment of the device on the surface being repaired is made in the form of a vacuum cap hinged to a shaped head piece rigidly fixed on the load-carrying platform. The control element of pressing and separation of the vacuum cap has the shape of an eccentric with a handle, which is fixed with a possibility of being rotated in vertical plane on one end face of a stiff tie-rod, the other end face of which is moulded inside an elastic membrane of the vacuum cap made from material with roughness of not more than Rz=30-120 mcm.

EFFECT: improving reliable fixation of the device on the surface being repaired; enlarging the range of the items being repaired; easier operation.
