At pipe jacking (microtunneling)<\/a><\/strong> the alignment is governed by a guiding system<\/strong> (laser or gyroscopic) inside the shield, external topography<\/strong> with automatic total stations and a continuous cycle of correction-verification-registration<\/strong> culminating in the as-built<\/em>.<\/p>

1) Operating principle (axis and slope control)<\/h2>

  1. Reading<\/strong>: the target\/target of the shield receives the laser beam<\/strong> or the orientation gyro\/INS<\/strong> and calculates horizontal\/vertical deviations from the theoretical axis.<\/p><\/li>

  2. Correction<\/strong>: the orientation cylinders<\/strong> apply micro-adjustments; if applicable, correction rings<\/strong> in the pipe line.<\/p><\/li>

  3. External verification<\/strong>: total station<\/strong> (or several) observes shield\/tail prisms and contrasts with the control grid.<\/p><\/li>

  4. Registration<\/strong>are recorded thrusts, torque, pressures, deflections<\/strong> and consolidate in the follow-up model<\/strong> and the as-built<\/em>.<\/p><\/li><\/ol>

    2) Laser vs. gyroscope (when to use each)<\/h2>
