Description

Technical Field

[0001] The utility model relates to the technical field of tunnel support construction, in particular to an inverted arch connecting plate protection tooling. Background Art

[0002] In the construction of soft surrounding rock, the invert is a reverse arch structure set at the bottom of the tunnel to improve the stress conditions of the upper support structure. It is one of the main components of the tunnel structure. On the one hand, the invert must effectively transfer the stratum pressure above the tunnel to the underground through the tunnel side wall structure or the load on the road surface. On the other hand, it can also effectively resist the reaction force from the stratum below the tunnel. The invert and the secondary lining constitute the whole tunnel and increase the structural stability.

[0003] Due to tunnel construction or design reasons, when the tunnel lower step arch frame is undergoing initial support grouting, the grouting material is likely to cover the invert arch connection plate, which has a significant impact on the invert arch construction. Measures need to be taken to chisel out the invert arch connection plate, which is both labor-intensive and time-consuming. At present, in order to solve the problem of the invert arch connection plate being covered, the traditional method is to use a pneumatic pick to chisel out the invert arch connection plate, or to chisel and weld the invert arch connection plate in the initial support surface; these measures are labor-intensive, time-consuming, and inefficient, and will result in incomplete welding and incomplete welds, and will cause certain damage to the initial support structure.
