Collar for marine pile repair and method of using the same

摘要

A collar for repairing a marine support has a tubular upper segment, a tubular lower segment, and a middle segment providing a transition region between the upper and lower segments. The collar can be opened and closed along a slit extending from the upper end of the collar to the lower end of the collar. To repair a marine support, the collar is opened and positioned so as to surround the marine pile and the extension. The collar is then closed and secured along the slit. The upper end of the collar is secured to the extension, and the lower end of the collar is secured closely along the perimeter of the pile. A flowable fill material is then injected into spaces between the collar and the marine support, filling or encasing voids or damaged areas on the marine support.

主权项

1. A collar for repairing a marine support including a marine pile and an extension upon an upper end of the marine pile, said collar being moveable from an open condition, in which said collar is positionable about the marine support, and a closed condition, in which said collar is positioned about the marine support, said collar comprising, when in said closed condition:
a tubular lower segment having a lower segment side wall defining a lower segment interior, a lower segment upper end, a lower segment lower end opposite said lower segment upper end, said lower segment lower end defining a lower end of said collar, a lower segment perimeter around said lower segment side wall proximate said lower segment upper end, and a lower segment diameter across said lower segment side wall proximate said lower segment upper end; a tubular upper segment having an upper segment side wall defining an upper segment interior and having an upper segment perimeter which is greater than said lower segment perimeter, and an upper segment diameter which is greater than said lower segment diameter; a conical middle segment connected to said lower end of said upper segment and said upper end of said lower segment, said middle segment providing a transition region between said upper segment and said lower segment and having a middle segment interior communicating with said lower segment interior and said upper segment interior and cooperating therewith to form a collar interior; an imparting means for imparting a tubular shape to said upper segment of said collar, said imparting means including a strap located proximate said upper end of said collar and encircling said upper segment of said collar, said strap having a first end and a second end opposite said first end; and a supplying means, formed in said upper segment side wall, for supplying flowable fill material to said collar interior from a source outside said collar, wherein said supplying means includes an at least one first opening through said upper segment, said at least one first opening being located below said strap, and at least one funnel-shaped pocket extending across said strap and defining at least one second opening that is outside of said upper segment and is located above said strap, said at least one pocket providing access to said at least one first opening from outside of said collar through said at least one second opening.
