Abstract

The invention discloses a tunnel engineering steel arch foot fixing method which includes the steps: firstly, initially erecting upper portions of two rows of steel arches, and respectively arranging one steel tube in middle of two rows of initially erected steel arches from two sides of surrounding rock; secondly, respectively arranged one connecting rod on two sides of the surrounding rock; thirdly, erecting upper portions of two lower rows of steel arches, and respectively arranging one steel tube in the middle of the two lower rows of steel arches and the middle of two adjacent rows of steel arches in the two lower rows of steel arches and two upper rows of steel arches from two sides of the surrounding rock; fourthly respectively arranging two connecting rods on two sides of the surrounding rock; fifthly, repeating the third step, the fourth step and the fifth step. According to the fixing method, fixing modes of steel arch supporting structures are optimized, and the fixing method solves the possible problem that supporting action of a traditional fixing method is insufficient.

Description

technical field [0001] The invention relates to the technical field of tunnel engineering. More specifically, the invention relates to a method for fixing the arch foot of a tunnel engineering steel arch. Background technique [0002] In the process of tunnel construction, controlling settlement and large deformation is a difficult point for tunnels with weak surrounding rocks. During the construction of many tunnel projects, settlement and large deformation occurred due to passing through weak strata, causing huge disasters. With the development of underground engineering theory, the composite lining structure is the most suitable structural form in weak strata, which can fully adapt to the space-time effect of surrounding rock stress. Both practice and theory have proved that steel arch support can enhance the initial support capacity, and it has also been widely used in a large number of tunnel projects. The steel arch frame usually adopts L, U, I-shaped steel, etc., an...
