Abstract
A process for the production of reinforced concrete walls in trenches involving preparing a trench of at least unit length, placing a reinforcing cage in the trench, fixing further reinforcing so that it will extend past the end of the unit, placing means to prevent the concrete from completely covering the further reinforcing and pouring the concrete.
Claims2
A process for the sequential segmental construction of a reinforced concrete unit comprising sequentially:
- (1) preparing a trench of dimensions at least equal to a selected portion of the total section to be constructed and having a length greater than an incremental segment to be constructed;
- (2) positioning a primary segment reinforcing cage in said trench;
- (3) positioning intersegmental perforate plate reinforcing partially overlapping said primary segment reinforcing cage;
- (4) positioning sealing means to define a segmental volume from which said plate reinforcing partially protrudes and effective to prevent concrete from flowing out of said segmental volume;
- and (5) pouring concrete into said segmental volume.

- 1. preparing a trench of dimensions at least equal to a selected portion of the total section to be constructed and having a length greater than the incremental segment to be constructed;
- 2. positioning a primary segment reinforcing cage in said trench;
- 3. positioning intersegmental perforate plate reinforcing partially overlapping said primary segment reinforcing cage;
- 4. positioning plural inflatable sealing means adjacent the ends of said cage to define a segmental volume from which said plate reinforcing partially protrudes;
- and
- 5. inflating said inflatable sealing means so that said sealing means are effected to prevent concrete from flowing out of said segmental volume;
- and
- 6. pouring concrete into said segmental volume.
