| description | The invention relates to a loop butting tunnel lining construction method which is used for performing a field operation of secondary tunnel lining concreting. The construction method is characterized in that at least two formwork groups and a formwork trolley are adopted; the formwork groups can be operated to be unfolded and folded by the formwork trolley; the unfolded formwork groups can be separated from the formwork trolley and stabilize in the tunnel to support prehardening concreting; the folded formwork groups can be carried by the formwork trolley to penetrate through the inner side of the unfolded formwork groups; and each formwork group can be in butt joint with one another on end surfaces. By means that a plurality of formwork groups are in butt joint circularly, circulating streamline operation of the formwork groups is operated, continuous concreting operation is realized in the field operation of secondary tunnel lining concreting, damages of concrete resulted from dislocation and squeeze cause |
