AI Technical Summary
Existing bridge shield tunneling crack repair devices are difficult to adjust the angle of the grouting pipe according to the crack shape. The grout is prone to sedimentation and stratification, and it is not easy to remove dust, resulting in poor repair quality and easy cracking.
A shallow crack repair device for bridge shield tunnels was designed, comprising a grouting component, a mixing component, and a cleaning component. The angle of the grouting pipe is adjusted by the cooperation of a positioning ball and a spherical shell. A bevel gear and a mixing rod are used to prevent mud sedimentation. A blower and a cleaning brush are used to remove dust.
It achieves full adhesion of mud, prevents sedimentation and stratification, ensures repair quality, effectively removes dust, and reduces the risk of secondary cracking.
