Abstract

The invention discloses a shield segment floating auxiliary adjusting device, which relates to the technical field of shield construction, and comprises a trolley, a hydraulic cylinder, a connecting end, an adjusting device, a ladder, a pulley, a track, a support beam, an inner medium hole and an outer medium hole, the device has the beneficial effects that a multi-body design mode is adopted, the gravity of the device can be rapidly adjusted, the requirements of different restraining forces are met, and restraining and adjusting of the buoyancy on the duct piece are achieved; the device can move synchronously with a trolley, the motion state of the device can be adjusted, and upward floating force generated by exposed segments can be restrained quickly; according to the invention, the problem of'head planting 'of the shield can be indirectly adjusted, auxiliary adjustment of the posture of the shield is realized, and the field operation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of shield tunneling, in particular to an auxiliary floating adjustment device for shield segment segments. Background technique [0002] With the vigorous development of my country's infrastructure industry, shield tunneling is widely used in highway, water conservancy, subway, railway and other engineering fields. It is estimated that by 2022, the total length of my country's subway, highway, railway and other tunnels will exceed 10,000 kilometers, of which medium-length and special-long Tunnels account for about 2 / 3. With the application of shield machines in tunnel engineering, the difficulty of attitude control of shield machines when tunneling downhill is becoming more and more prominent. [0003] Whether the posture of the shield machine is correct or not is crucial to the final formation of the tunnel. As the core component of the shield excavation, the cutting tool plays a pivotal role in the excavati...
