Formwork system

A formwork system for tunnel construction, comprising:

• at least one support arrangement for supporting at least one formwork element, the formwork system further comprising at least one concrete pump, a plurality of concrete feeders to the at least one formwork element and at least one control unit, at least two pressure sensors arranged at vertically different positions on the at least one formwork element or on the support arrangement to measure a pressure acting on the at least one formwork element at at least two different heights of the formwork element, the at least one control unit is connected to a control unit of the formwork system and controls the concrete feeders individually as a function of a signal of the at least two pressure sensors, and wherein the at least one support arrangement has at least one hydraulic support beam for supporting the at least one formwork element, the control unit also directly controls support pressure on the at least one hydraulic support beam as a function of pressure values measured with the at least two pressure sensors, and wherein the at least one control unit is connected to at least one vibrator, the at least one vibrator being integrated into the at least one formwork element and the control unit can individually control a single vibrator dependent on values of the at least two pressure sensors in order to achieve selective compacting of poured concrete in different areas of a tunnel wall, the tunnel wall being directly connected to the at least one formwork element by the poured concrete filling an empty space between the at least one formwork element and the tunnel wall, thereby ensuring a concrete quality of the poured concrete filling the empty space with a highest possible homogeneity over the tunnel wall, wherein the at least one support arrangement contains the at least one hydraulic support beam to support the formwork elements with a specified pressure against the poured concrete.
