Abstract

The invention relates to the technical field of tunnel construction, in particular to a supporting component, a supporting method and a dismantling method. Wherein the supporting part comprises a first supporting piece, a second supporting piece and a third supporting piece, the first supporting piece is used for supporting the whole tunnel, the second supporting piece is vertically arranged, and the second supporting piece is connected with the first supporting piece and used for supporting the first supporting piece and providing support for the first supporting piece; the two ends of the third supporting piece are connected with the first supporting piece and the second supporting piece respectively, the third supporting piece can play an auxiliary supporting role on the first supporting piece, and the supporting effect is further improved. The whole supporting piece does not need to be embedded through concrete, the problem that the concrete on the whole supporting piece is dismantled does not exist during dismantling, therefore, the problems that flying dust is large, noise is large, and a large amount of construction waste is generated do not exist, the cleaning work amount is small, and the construction period can be shortened.

Description

technical field [0001] The present disclosure relates to the technical field of tunnel construction, and in particular, to a support component, a support method and a removal method. Background technique [0002] At present, the double-sided guide pit method or the middle partition method (also called the CD method) is mainly used for the excavation of the arch of the subway underground excavation station in China. The double side wall pilot pit method is to use the temporary support of the two middle partition walls to divide the entire station vault into three sections: left, middle and right, with the left and right pilot holes first, followed by the middle section. The CD method is to divide the entire station vault into left and right sections for construction by the middle partition support, and excavate one side of the tunnel first. The construction process of this method is simpler than the double side wall method. Both the double-side wall method and the CD method ...
