Abstract

The invention discloses a construction method for dismantling a temporary inverted arch of an existing tunnel that passes under an oblique intersection, which is applied to the oblique section generated between the tunnel under construction and the existing tunnel to carry out the dismantling construction of the temporary inverted arch; The force of the tunnel is different. The oblique section between the tunnel under construction and the existing tunnel is divided into various demolition sections, and one of the demolition sections is selected as the test section, and the demolition work is carried out step by step on the test section. , different construction methods can be adopted for each section in a more targeted manner to improve construction safety.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a construction method for removing a temporary inverted arch of an existing tunnel that passes under an oblique intersection. Background technique [0002] In the process of traffic construction, tunnel construction is a common engineering structure. We are usually familiar with single tunnel construction, but with the acceleration of road construction, there have been many constructions of multi-line tunnels at the same location. [0003] The construction of passing through the existing tunnel is not only difficult, but also has certain potential safety hazards, especially in the oblique section between the tunnel under construction and the existing tunnel, and during the dismantling of the temporary inverted arch, there will be problems in the existing tunnel. Subsidence problems arise. In order to prevent the uneven settlement of existing tunnels and ensure the op...
