Title:
SHIELD SEGMENT CAPPING BLOCK ASSEMBLING APPARATUS AND CONSTRUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2018/223730
Kind Code:
A1
Abstract:
A shield segment capping block assembling apparatus. By means of alternate supporting of the jacking connection of capping segments by two lead screws on a capping segment supporting frame and the jacking connection of the capping segments by a jack of the capping segments on a middle shield of a shield tunneling machine, the capping segments are always in a jacking connection stress state, so that loss of support of the first ring of capping segments due to that the jack of the capping segments on the middle shield of the shield tunneling machine retracts after the shield tunneling machine conducts tunneling towards the next ring and when the next ring of capping segments are assembled is avoided, and the problems of misalignment and breakage of the capping segments of this ring caused by stress release are resolved. In addition, also disclosed is a construction method for the shield segment capping block assembling apparatus. The present invention improves the ring formation quality of segments, is easy to operate, and is particularly suitable for use in shield tunnel construction.
