Abstract
A formwork system (10; 60), especially for tunnel construction, includes at least one support arrangement (14) for supporting at least one formwork element (16-26; 72-78). The formwork system further includes at least one concrete pump (36), a plurality of concrete supply units (42) for supply to the formwork element and at least one controller (32). On the formwork element (16-26; 72-78) and/or on the support arrangement (14) at least two pressure sensors (44; 92) are disposed at different vertical positions and are connected to the controller (32) of the formwork system, which pressure sensors (44; 92) are designed to measure the pressure acting upon the formwork elements (16-26; 72-78) at a minimum of two different heights of the formwork element, and that the controller (32) is designed to control the concrete supply units (42) individually, dependent on the signal from the pressure sensors (44; 92).
