Abstract:

The water seepage treatment program and materials of deformation joints of connection gallery of Metro tunnel is determined according to water seepage treatment principles. The problems of water sealing, including sand bursting, grouting leaking, grouting pipe installation and asymmetrical uplifting of structure soleplate, are analyzed. The rational grouting control standards are decided, the grouting effect and safety of the tunnel structure are guaranteed.
