Abstract
The invention discloses a bidirectional prestressing type preassembled working open caisson which is applied to pipe jacking projects. The open caisson is rectangular and is formed by splicing prefabricated well pieces with U-shaped and straight sections. Cantilever ends at two sides of each U-shaped well piece are different in length; the horizontal U-shaped well pieces are spliced dissymmetrically according to the lengths of the cantilever ends at two ends; and the vertical adjacent U-shaped well pieces are spliced in a staggered way according to the sizes of the cantilever ends. All the vertical well pieces and the horizontal well pieces are connected through prestressed reinforcements. The vertical prestressed reinforcements are connected through connectors at the transversal abutted seams. The vertical prestressed reinforcements in the well pieces of the blade foot section are subjected to non-bonding treatment. Shear key structures are arranged on the sections of prefabricated well pieces at two sides of transversal abutted seams; and the well pieces provided with the shear key structures adopt a matching prefabrication method to ensure the mounting precision of the open caisson. When in prefabrication, the reinforcements are inserted into a prestressing duct. The bidirectional prestressing type preassembled working open caisson disclosed by the invention remarkably improves the filed casting efficiency of the open caisson, shortens the pipe jacking construction period, and accords with the architectural notion of 'low carbon economy and green construction'.
