摘要:
It is an aim of the invention to provide a method for determining the torque of an auger of a pile driving rig (10), by which the torque can be accurately determined. In the method according to the invention, the torque of the auger of the pile driving rig (10) is determined by measuring at least one of the following variables in the structures of the pile driving rig (10): the force effected by the torque on at least one point in the structures of the pile driving rig (10), the elongation caused by the force, the strain caused by the force, or the deformation caused by the force; as well as by calculating the torque of the auger from the measurement result thus obtained. Moreover, it is an aim of the invention to present an apparatus for implementing the method according to the invention, and a pile driving rig (10).
摘要:
The present invention relates to a method for stabilizing the ground, in which raw materials in at least two different tanks (1, 2) are mixed together in the desired proportions and led to the ground. Furthermore, the invention relates to a system for stabilizing the ground, which comprises tanks (1, 2) to contain the raw materials which are to be mixed, and apparatuses (3, 4, 5) for mixing the raw materials and leading the substance to the desired place. Raw materials in a method formed in accordance with the invention are mixed together in a transferring apparatus (3) and led immediately thereafter to the desired place by the feeding apparatus (4). A transfer apparatus (3) for raw materials in a system formed in accordance with the invention is a mixing apparatus for the raw materials, into which the raw materials are arranged so that they can be transferred from the tanks in the desired proportions, and the mixing apparatus (3) is connected to the feeding apparatus (4) for the mixed substance.
