A shield receiving end structure of a cross passage with translation by excavation

Abstract

This utility model discloses a shield tunnel receiving end structure for a transverse tunnel with a cut-and-cover tunnel, relating to the field of tunnel construction technology. It includes: a transverse tunnel with a cut-and-cover tunnel, one side of which is connected to a cut-and-cover tunnel, and a shield support frame at its bottom; a grouting reinforcement body located on the other side of the transverse tunnel, extending longitudinally along the shield tunnel for a predetermined length, with multiple grouting holes and an internal support structure at its end; and a temporary support system including at least two transverse waist beams, multiple transverse waist beams vertically spaced and fixed to the internal support structure, each transverse waist beam being fitted with at least two diagonal bracing beams, the upper end of which is fixedly connected to the corresponding transverse waist beam, and the other end of which is fixedly connected to the shield support frame. This utility model can reinforce the shield tunnel receiving end of a transverse tunnel with a cut-and-cover tunnel, ensuring sufficient structural strength, eliminating the dependence of shield tunnel receiving on the station construction progress, thereby significantly shortening the construction period and reducing construction risks.
