摘要： Trenchless methods for forming a curved hole channel with a steel sleeve and pipeline lifting are provided, including steps of: (T1) drilling a straight hole channel, and inserting the steel sleeve into the straight hole channel; (T2) inserting a guiding pipe into the steel sleeve, and determining a bending direction of a hole channel to be formed; and (T3) inserting a flexible steel-wire pipe into the guiding pipe, and punching to form the curved hole channel. With applying the creative trenchless method for forming the curved hole channel, a specially-made grouting pipe is accurately inserted to a bottom of a subsiding pipeline section, so that a polymer material is conveniently injected to a bottom of a disease position. Though utilizing an expansion force generated by the polymer material, the subsiding pipeline section is uplifted, so as to realize trenchless repairing.
