Abstract

The invention discloses a method for construction through a vertical-height-continuous-gradual-change-type section tunnel secondary lining trolley. The vertical-height-continuous-gradual-change-type section tunnel secondary lining trolley comprises a new crane beam, a vertical column heightening joint and a side wall formwork, wherein the new crane beam is arranged at the lower end of an old cranebeam of a secondary lining trolley with the standard section, and the vertical column heightening joint is arranged at the lower end of the old crane beam or between the old crane beam and the new crane beam; and the side wall formwork is arranged between a first side formwork and a second side formwork of the secondary lining trolley with the standard section. In the long-distance longitudinal continuous-gradual-change-type section tunnel lining construction process, the trolley is convenient to adjust and transform, the assembly formworks are calculated and prefabricated in advance according to the modulus, assembly is easy and rapid, and the continuity of lining construction is ensured.

Description

technical field [0001] The invention relates to the technical field of underground structure construction, in particular to a construction method using a vertical height continuous gradient cross-section tunnel secondary lining trolley. Background technique [0002] At present, with the rapid development of subway construction in my country, the secondary lining trolley is an indispensable special equipment in the secondary lining construction of the tunnel. However, for the vertical height continuous gradient section tunnel, the standard section secondary lining trolley cannot be reused, and generally small formwork construction is required, which leads to slow construction speed, poor lining quality, and requires more labor input, construction period and project cost. greatly increase. SUMMARY OF THE INVENTION [0003] In view of the problems existing in the prior art, the purpose of the present invention is to provide a vertical height continuous gradient cross-section...
