Abstract

The invention provides a rectangular shield tunnel lining-shaped rectification device and a rectification method. An upper beam and a lower beam are driven by a top supporting device to extend along a vertical direction, so a multi-ring lining ring is pressed against; the shape of the multi-ring lining ring can be maintained and rectified; a problem of difficulty in assembling for post-pipe sheets due to bearing deformation of the tunnel lining can be effectively solved; the rectification device can be simply and reliably operated; top supporting action points of the upper beam and the lower beam are formed on a seam crossing part of two lining rings; and damage to the lining can be avoided and construction safety can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of rectangular shield tunneling, and mainly relates to a lining shape correction device and correction method for rectangular shield tunnels. Background technique [0002] During shield construction, after the tunnel lining comes out of the tail of the shield, due to the action of earth pressure, the lining will be deformed to varying degrees, such as figure 1 shown. exist figure 1 In the above, the assembled lining rings 3, 4 and 5 are deformed under the action of earth pressure after they come out of the shield tail 1. When the deformation of the assembled lining ring 3 exceeds the specified value, the lining ring 2 cannot be assembled normally. (In the shield construction, the lining is first assembled into a lining ring by prefabricated segments piece by piece, and then the above-mentioned lining ring of a ring finally forms the lining of the tunnel). [0003] The circular shield adopts a rounder to m...
