ABSTRACT:
The present invention provides a wiper, grouting seal and diaphragm apparatus for use on a tubular sleeve of a structure wherein the sleeve receives a piling. The apparatus has a housing with a bore therethrough. A manifold seal extends interior of and circumferentially around the housing. Fluid receiving means are provided for communication with a pressure conduit extendable from the manifold to the structure. Fluid ejecting means are defined on the manifold for selective discharge of fluid injectable through the conduit and the manifold and interior of the sleeve. A longitudinally shiftable cage member initially defines the interior wall of the housing and has means engageable by the lower end of the piling for shifting of the cage member whereby the manifold is urged away from the housing and against the piling. Diaphragm seal means are initially held by the housing and across the bore, the seal means being rupturable by the cage member upon shifting of the cage member by the piling. In an alternative embodiment, the cage member is replaced by securing means which are circumferentially extendable exteriorally around the diaphragm sealing means for initially positioning the manifold within the housing and substantially out of the bore of the housing when the manifold is in retracted position and permitting the manifold to effectively expand into the bore upon rupture of the seal means, the relative position of the manifold and the securing means providing effective sealing engagement of the seal means and the manifold.
