    Molded Walls

    Molded walls must be executed in order to obtain a work according to the project. Verticality and rotation must obey a careful work plan to guarantee the impermeability of the joints.

    • Grab rotation, about Z axis, (with 1° resolution)
    • Deviation, X and Y axis, from the vertical (with 1 cm resolution)
    The data is acquired by sensors installed in the excavation equipment. The inclination sensor can be connected to the datalogger by cable or via radio. The JET DSP 100 / D can record the excavation data as a function of depth. In the course of the necessary blows for the execution of the molded wall, the individual data of each blow are recorded. The last hit data is also recorded in order to analyze the excavation on the PC when returning to the office. The datalogger can be connected via PC. In this way, it is possible to calibrate the sensors, introduce data acquisition parameters and display values in large-scale graphs.

    Vibroflotation

    The Vibrofloating technique uses a vibrating torpedo that penetrates the ground.

    This is compacted by virtue of this vibratory action. Gravel-like materials are accumulated in a free space produced by vibration. These materials will increase the solidity of the ground.
