Abstract
A caisson or casing 107 for installing a sheet 102/103 into a ground or underwater location, the caisson 107 having a shaped wall 107.1, which is open for a predetermined length and is adapted to receive and connect to an excavation means 3 within the confines of the caisson or casing 107. In at least one embodiment, the system includes a drilling assembly 3 for insertion of a caisson or casing 1, the drilling assembly 3 having one or more expanding drill bits 4 which are adapted to be driven by a drilling or rotation motive device 5, the expanding drill bits 4 being adapted to be arranged with respect to the caisson or casing 1 in use, so as form a hole or bore which substantially conforms to, or substantially overlaps with, the shape of the caisson or casing 1.
Claims17
A method of constructing a retaining wall utilizing a caisson or casing for a ground or underwater location, the method comprising:
- installing a first retaining wall element into said ground or underwater location, said first retaining wall element including a join formation or clutch on a side thereof;
- providing the caisson or casing having a shaped wall which is open for a predetermined length which provides free sides, with at least one of said free sides having a join formation or clutch;
- closing off the shaped wall of said caisson or casing with a connection section having
- at least one wall-mating join formation or clutch adapted to connect to an open side of said shaped wall, and
- at least one element-mating join formation or clutch adapted to connect to said join formation or clutch on said side of said first retaining wall element;
- attaching said at least one element-mating join formation or clutch of said connection section to the at least one join formation or clutch of said first retaining wall element,
- inserting an excavation means within an area defined by said caisson or casing and connecting the excavation means to the caisson or casing, said excavation means being adapted to excavate ahead of a leading edge of said caisson or casing;
- activating said excavation means so said caisson or casing and said connection section enters the excavated ground or underwater location to a predetermined depth;
- once said predetermined depth is achieved, withdrawing the excavation means from said caisson or casing;
- withdrawing said connection section from said first retaining wall element and said caisson or casing;
- attaching a second retaining wall element to the first retaining wall element, and sliding said second retaining wall element to the predetermined depth inside said caisson or casing, said second retaining wall element including a join formation or clutch adapted to join to said first retaining wall element;
- and
- withdrawing said caisson or casing from said second retaining wall element.
