Filed: 1947-11-10
Abstract: 638,682. Concrete piles. HOLMES, A. B. Nov. 10, 1947, No. 29869. [Class 68 (ii)] A concrete pile is cast in situ by first driving a bore tube, with a solid detachable shoe 23, into the ground, filling the tube with concrete, withdrawing the tube, and tamping the concrete, and subsequently introduced concrete, by a tamping member which is guided by a member positively located at its lower end in the solid detachable shoe 23. As shown, the tamping member comprises a drive feed tube with a detachable shoe 26, a shoe being abandoned in the pile after each tamping operation. The guiding is effected by the shoe 26 engaging a rod 24 which is located at the bottom of a recess in the shoe 23. A bracket detachably secured to the top end of the guide rod 24 prevents wobbling of the drive feed tube. The guide means are finally removed. The shoes 26 are of smaller diameter than the fixed solid body 23, the drive feed tube thus being withdrawn in clean condition due to the concrete between the drive feed tube and the walls of the bore. A small quantity of dry concrete is used in the first charge of the drive feed tube after each tamping operation to reduce the possibility of back pressure. After the last tamping operation a wet charge is preferably used by which the space occupied by the drive feed tube is easily filled. Reinforcement, preferably of tubular or cylindrical shape may be included in the pile. The central guide rod 24 may be replaced by two or more rods which are engaged in an annular recess in the shoe 23, the shoes 26 being provided with rebated surfaces to register with the rods. Specification 621,450 is referred to.
