Abstract

The invention discloses a supporting structure and method for tunnel reconstruction and extension engineering which solve the problems that tunnel structure reconstruction and extension construction needs input of a large amount of manpower, equipment and financial resources, and the construction risk is generated easily. An 'underground diaphragm wall' structure for effectively preventing lateraldeformation is formed through supporting assemblies so as to meet reconstruction and extension construction and stability of tunnel structures at a soft stratum or a shallow-embedded section. According to the technical scheme, the supporting structure comprises the first vertical supporting assembly and the second vertical supporting assembly, the distance is set between the first vertical supporting assembly and the second vertical supporting assembly in a spaced mode, the first vertical supporting assembly and the second vertical supporting assembly each comprise a plurality of rows of pipesets, each row of pipe sets comprises a plurality of first pipe fittings horizontally arranged in sequence from top to bottom, and the set space exists between the center lines of every two adjacentrows of pipe sets; and the semicircular supporting assemblies are arranged between the first vertical supporting assembly and the second vertical supporting assembly.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering, in particular to a support structure and method for tunnel reconstruction and expansion projects. Background technique [0002] With the rapid development of our country's national economy, the traffic volume has increased rapidly. Due to the low design standards of some long-established roads and even expressway tunnels, the traffic capacity cannot meet the growing traffic demand, thus affecting the rapid economic development. , needs to be rebuilt and expanded to achieve the corresponding service level. Thirdly, compared to rebuilding a new tunnel, the reconstruction and expansion of the tunnel is carried out on the basis of the original tunnel, and has less excavation. You can refer to the engineering geology, hydrogeology and other data at the time of initial construction, or directly in the tunnel. Supplementary surveys of severely diseased locations can save a lot of surve...
