The system autonomously detects using an object sensor system an orientation and location of the pile located within a threshold distance of the system. The system autonomously positions a tool of the autonomous pile driving system based on the detected orientation and location of the pile. The system autonomously picks up the pile using the positioned tool of the autonomous pile driving system. The system autonomously positions the pile based on the target location. The system autonomously drives the pile into ground at the target location.

The invention relates to a method and an arrangement for monitoring a structural foundation in a ground for a structure, wherein ground parameters are determined for the ground, based on the determined ground parameters a preliminary ground model is calculated by means of a computer unit, on which a design of the structural foundation is laid out taking into consideration specification data of the structure to be erected, during and/or after the production of the structural foundation measured values relating to settlements, distortions and/or forces on the structural foundation or the structure are recorded by means of measuring means, the measured values are forwarded to the computer unit which checks if the measured values are consistent with the preliminary ground model, and if the measured values are not consistent with the preliminary ground model, a subsequent ground model, in which the measured values are consistent with the new ground model, is calculated by the computer unit.

A system for monitoring a foundation includes a sensor cartridge assembly. The sensor cartridge assembly includes a sensor disposed in a sensor tube and a sensor head attached to an end of the sensor tube. Wiring coupled to the sensor and routed in the sensor tube to the sensor head conveys power and/or telemetry between the sensor and a controller. The sensor tube is configured to be inserted into a raceway attached to a foundation. The raceway may be within the foundation and/or located at a perimeter of the foundation. A method for monitoring a foundation includes deriving an elevation of the foundation at the location of the sensor based on pressure measurements made by the sensor within the sensor tube.

The present disclosure provides a method for measuring flow velocity distribution of groundwater using distributed optical fiber with active heating, comprising: setting and optimizing field test parameters; conducting a background temperature monitoring test; performing a line-source active heating distributed temperature measurement test, including conducting multiple rounds of heating tests; denoising the obtained thermal plume attenuation signal data of the groundwater; and fitting the groundwater velocity-depth curve in the borehole by monitoring and analyzing the temperature difference signal between the internal temperature and the external temperature of the composite heating optical cable in a single depth section of the borehole, thereby obtaining a distributed groundwater velocity data set. The method of the present disclosure solves the problem that the existing groundwater flow velocity measurement technology cannot simultaneously conduct continuous and distributed measurements, improves the efficiency of groundwater velocity measurement, and it can avoid groundwater contamination during the measurement process.
