Apparatus and method for measuring spatial movements of plant structures

摘要

An apparatus and method for measuring spatial movements of plant structures, such as pipes, due for example to movement of the ground in presence of landslide phenomena, subsidence, collapse, or differential settling. The measuring apparatus includes at least one ground station that communicates with at least one corresponding signal-sending satellite station, the ground station being connected in a movable manner to a support constrainable in a fixed manner to the plant structure, the ground structure having an initial azimuthal orientation and an initial azimuthal height. The ground station is moved with respect to the support via a mechanism for adjusting the orientation and height of the same to compensate for an instantaneous orientation and height that are different from the initial orientation and height.

1. An apparatus for measuring spatial movements of a plant structure comprising:
at least one ground station that communicates with at least one corresponding signal-sending satellite station, the ground station being connected in a movable manner to a support constrainable in a fixed manner to the plant structure, the ground structure having an initial azimuthal orientation and an initial azimuthal height, wherein the ground station is moved with respect to the support via a mechanism to adjust an orientation and height of the ground station so as to compensate for an instantaneous orientation and height that are different from the initial orientation and height, wherein the ground station is integrally constrained on an upper part to a support surface and the support comprises a first platform to which the support surface is connected, the mechanism to adjust the orientation and height of the ground station modifying mutual positioning between the support surface and the first platform, and wherein the mechanism comprises at least a first actuator connected to a plurality of worm screws constrained in a rotatable manner to the first platform and integral with the support surface, and at least a second actuator configured to rotate the support surface.
