Abstract
A grout seal for a piling driven through a cylindrical platform leg into submerged strata includes an array of spring members having upper and lower end portions of cylindrical configuration, the lower and upper extremities of the portions, respectively, defining boundaries of inward diversion to form the central portion of the array. A reinforced elastomeric outer cover is provided for the central portion of the array. The array also includes an elastomeric pad mounted within the array and having a cylindrical inner face for contact with the pilings and an outer face conforming with the central portion of the array.
Claims17
A grout seal for a piling driven through a cylindrical platform leg into submerged strata which comprises:
- a. an array of spring members having upper and lower end portions of cylindrical configuration, the lower and upper extremities of said portions, respectively, defining boundaries of inward diversion to form a central outwardly bowed portion of said array,
- b. a reinforced elastomeric outer cover for said central portion of said array, and
- c. an elastomeric pad mounted inside said array having a cylindrical inner face for contact with said piling and an outer face conforming with said central outwardly bowed portion of said array.
A grout seal for a piling driven through a cylindrical platform leg into submerged strata which comprises:
- a. a cylindrical array of springs inwardly diverted from upper and lower end portions and centrally bowed outwardly,
- b. a reinforced elastomeric outer cover for the outer surface of said springs having upper and lower ends and extending from said upper end of said springs to said lower end of said springs,
- c. said upper and lower outer cover ends being integrally connected by a central reinforced elastomeric member having a cylindrical outer face for contact with the inner surface of said leg, thereby forming an annular cavity between said central member and said outer cover,
- d. an elastomeric pad having a cylindrical inner face for contact with said piling and an outer face conforming with said centrally bowed portion of said array and integral with said outer cover,
- e. means for captivating said ends of said springs, and
- f. means extending from said lower end portions of said array for contacting said piling to provide a lip seal between said piling and said array.
A grout seal for a piling driven through a cylindrical platform leg into submerged strata which comprises:
- a. a cylindrical array of springs inwardly diverted from upper and lower end portions and centrally bowed outwardly,
- b. a reinforced elastomeric outer cover for said central portion of said array,
- c. a reinforced elastomeric annular ring molded integrally and centrally to said outer cover,
- d. an annular reinforcing element molded in the periphery of said annular ring,
- e. means for securing said annular ring to said leg,
- f. an elastomeric pad having a cylindrical inner face for contact with said piling and an outer face conforming with said centrally bowed portion of said array and integrated with said outer cover,
- g. means for captivating said ends of said springs, and
- h. means extending from said lower end portion of said array for contacting said piling to provide a lip seal between said piling and said leg.
A grout seal for a piling driven through a cylindrical platform leg into submerged strata which comprises:
- a. a cylindrical array of springs inwardly diverted from upper and lower end portions and centrally bowed outwardly,
- b. a reinforced elastomeric outer cover for said central portion of said array,
- c. an upper reinforced elastomeric outer cover for said upper end portion of said array being integral with said outer cover for said central portion and contacting the inner surface of said leg,
- d. an elastomeric pad having a cylindrical inner face for contact with said piling and an outer face conforming with said centrally bowed portion of said array and integrated with said outer cover,
- e. means for captivating said ends of said springs, and
- f. means extending from said lower end of said array for contacting said piling to provide a lip seal between said piling said said leg.
A grout seal for a piling driven through a cylindrical platform leg into submerged strata which comprises:
- a. a cylindrical array of springs inwardly diverted from upper and lower end portions and centrally bowed outwardly,
- b. a reinforced elastomeric outer cover for said central portion of said array,
- c. an upper reinforced elastomeric outer cover for said upper end portion of said array being integral with said outer cover for said central portion and contacting the inner surface of said leg,
- d. an elastomeric pad having a cylindrical inner face for contact with said piling and an outer face conforming with said centrally bowed portion of said array and integrated with said outer cover,
- e. means for captivating said ends of said springs, including
- i. a first cylindrical ring including an annular groove and being fixed to the inner surface of said leg,
- ii. a second cylindrical ring being fixed to the lower end of said first cylindrical ring, and
- iii. said upper end of said springs being retained in said annular groove by said second cylindrical ring, and
- f. means extending from said lower end of said array for contacting said piling to provide a lip seal between said piling and said leg.
