Abstract

The invention discloses a construction method for removing a temporary inverted arch of down-traversing obliquely crossed tunnels. The construction method is applied to obliquely crossed zones generated by tunnels under construction and the existing tunnels for demounting the temporary inverted arch. According to different kinds of stress of the tunnels under construction, the obliquely crossed zones generated by the tunnels under construction and the existing tunnels are divided into various demounted sections, one demounted section is selected as an experiment section, and the experiment section is gradually demounted sectionally in several times. Different construction methods can be adopted for all sections more specifically, and the construction safety is improved.

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...
