Water Pipe-aided Structural Settlement Measuring System

Measure structural settlement. This system is designed to measure settlement effects on existing structures during or after tunneling just under, or adjacent to, the structures or during or after nearby pit excavation works. The system consists of a reference water tank, detector and conditioner. The reference water tank is fixed at a site where it is not affected by structural settlement, while the detector is installed at a measuring site where the structure is predicted to settle. The tank and detector are connected with each other via a communicating tube to electrically measure the difference in water levels between them.
