Embodiment Construction

[0031] The specific embodiments of the present invention are described below so that those skilled in the art can understand the present invention, but it should be clear that the present invention is not limited to the scope of the specific embodiments. For those of ordinary skill in the art, as long as various changes Within the spirit and scope of the present invention defined and determined by the appended claims, these changes are obvious, and all inventions and creations using the concept of the present invention are included in the protection list.

[0032] During tunnel excavation using the shield method, since the segment lining ring 5 will be subjected to the axial force of the shield machine due to inertia when the segment lining ring 5 just leaves the shield machine, the segment lining ring 5 will not float up. The mechanism is far away, and the segment lining ring 5 is only subjected to the buoyancy and gravity of the slurry in the slurry. If the buoyancy is greate...

Abstract

The invention provides a shield tunnel anti-floating segment and processing and applying methods thereof and relates to the technical field of shield tunnel construction. The shield tunnel anti-floating segment comprises a top segment, the outside of the top segment is provided with a groove inside which a grout pocket is fixed, the grout pocket is made of flexible materials, the bottom of the groove is provided with a grouting hole penetrating through the top segment, and the grouting hole is fixedly provided with a grouting pipe communicated with the grout pocket. The shield tunnel anti-floating segment solves the problem of floating of lining rings of shield tunnel segments in the prior art.

Description

technical field [0001] The invention relates to the technical field of shield tunnel construction, in particular to an anti-floating segment for shield tunnels, a processing method and a use method thereof. Background technique [0002] The shield method is a fully mechanized construction method in the underground excavation method. It is to push the shield machine in the ground, and support the surrounding rock through the shield casing and segments to prevent collapse into the tunnel. A mechanized construction method in which the soil is excavated with a cutting device in front of the excavation face, transported out of the hole by an excavation machine, pushed in by a jack at the rear, and assembled with prefabricated concrete segments to form a tunnel structure. [0003] In recent years, the shield method has been widely used in the construction of subways and cross-river and sea-crossing tunnels in major cities due to its advantages of safety, reliability, speed and env...
