Construction method for large section and multiple sections tunnel lining

Abstract

The invention discloses a large cross-section and multiple cross-section tunnel lining construction method. Combined type lining trolleys are chosen to carry through the trolley assembly lining to the cross-section, and adding a gantry mounting on the basis of a normal trolley single gantry mounting can form an assembled and detachable lining trolley. Steel molding plates, road wheels, main gantry mountings, etc. are listed in unchanged components in the process of the assembly trolleys with different cross-sections, and lateral adjusting driving screws, upper platform chord members, upper platform upright posts, lining steel arches, etc. are listed in adjustable components. In the process of the construction from one cross-section to another cross-section, the unchanged components do not change, and only the changeable components are carried through the refitting and assembly. The construction method has the characteristics of fast construction progress, low cost, easy control of site construction management, etc., can save a great deal of manpower, physical resources and financial resources and obtain good technical economic effect, and has the remarkable economic, social and environmental benefits; the invention is especially adapted to the large cross-section and multiple cross-section type lining construction of tunnels and underground constructions.

Description

technical field [0001] The invention belongs to the technical field of tunnel engineering construction, in particular to a large-section and multi-section tunnel lining construction method. Background technique [0002] In recent years, with the development of my country's economic construction and the continuous acceleration of urbanization, the demand for infrastructure, especially the construction of transportation facilities, has been increasing, and a large number of large-section and multi-section tunnel projects have appeared, and the scale is getting larger and larger . [0003] For large-section and multi-section tunnel construction schemes, it is not only necessary to meet the special requirements of special geological and topographical conditions, line-bridge-tunnel connection methods, and overall route alignment, but also to consider whether it is conducive to the overall alignment planning and construction of the highway. Linear optimization, whether good techni...

Problems solved by technology

[0004] At present, for the lining construction of large-section and multi-section tunnel projects, full-hydraulic lining trolleys with different sections are mostly used for construction. There are different types of sections, that is, how many lining trolleys need to be replaced, and multiple lining trolleys need to be assembled and installed separately, which will inevitably cause a lot of waste of manpower, material resources, and financial resources, and directly affect the progress of the entire project.
