Abstract

The invention provides a traffic tunnel crack plugging and reinforcement method used in a vibration-disturbed environment, and relates to the technical field of crack repair in traffic tunnels. The grouting material is poured by using the method of minimal damage and adopting the pinhole oblique side drilling method. , Reinforcing while plugging. The specific method is to use a cutting machine to cut grooves along the seam first, clean them up and fill them with special cement for sealing, then make grouting holes along both sides of the seam to 1/3 to 1/2 of the seam. The grouting nozzle is installed in the hole, the grouting material is injected, and through the sealing effect of the cutting groove, and through the cross grouting, the grout is injected into the depth of the crack, so that the lining concrete at the crack is restored to form a whole, which solves the existing problems in the prior art. The technical problem that underground engineering cannot effectively plug leaks in the vibration-disturbed environment prevents leakage and cracking due to vibration-disturbed deformation and damage, and restores the compactness and structural integrity of the lining concrete.

Description

technical field [0001] The invention relates to the technical field of repairing cracks in traffic tunnels, in particular to a method for plugging and reinforcing cracks in traffic tunnels in a vibration disturbance environment. Background technique [0002] The subway adopts ballastless track integrated ballast bed technology to adapt to the operation of subway trains. When the subway trains pass through the underground passage, there will be vibration disturbances to the entire ballast bed and the underground passage. When the subway trains pass through the interval subway station, it will also bring great vibration disturbance to the concrete structure of the station, and if the top of the subway station is a municipal road, when there are cars passing on the road, it will also cause great shock to the concrete structure of the subway station. There are certain vibration disturbances, and the subway station is in the operating environment of double vibration disturbance a...
