Abstract

The invention relates to a butting auxiliary device for pipe rings and a method for replacing shield tail brushes and belongs to the field of tunnel shield engineering. The butting auxiliary device comprises a plurality of guide units arranged between the butting end faces of the two pipe rings and a plurality of positioning units arranged on the end face of the pipe ring on one side; the shield tail brushes are arranged on the outer side of the pipe ring provided with the positioning units; the guide units comprise guide bodies; guide bevels are arranged at one ends of the guide bodies; the positioning units comprise first faces, second faces and third faces which are connected in sequence, and the first faces and the third faces are perpendicular to the second faces; and positioning boltconnection parts are arranged at one ends of the first faces, positioning bolt connection holes are formed in the second faces, and positioning grooves matched with the guide units in shape are formed in the third units. The butting problem of secondary pipe ring splicing is solved, and all the shield tail brushes can be replaced.

Description

technical field [0001] The invention relates to a butt joint auxiliary device, in particular to a pipe ring butt joint auxiliary device, and also relates to a method for using the device to replace a shield tail brush, which belongs to the field of shield tunneling engineering. Background technique [0002] With the development of urbanization in my country, the shield tunneling method is widely used in subways and cross-river and sea-crossing tunnels. Therefore, the problems encountered in shield tunnel construction are becoming more and more prominent. Secondary assembly and docking is a difficult point in shield tunneling construction. [0003] After long-distance continuous propulsion of the shield machine or due to poor quality control or improper operation such as the quality of hand-applied grease, the amount of grease filled for the first time, the control of synchronous grouting pressure, the control of synchronous grease injection, that is, the gap between the shiel...
