Problems solved by technology

Although the segment annular seam and the segment longitudinal seam are sealed with sealing strips, they are easily not tightly sealed and local leakage occurs. Groundwater can easily enter the tunnel through the segment annular seam and segment longitudinal seam, which not only increases the The later maintenance cost also affects the operational safety of the tunnel. Therefore, how to waterproof and prevent leakage is a top priority

Abstract

The invention belongs to the technical field of shield tunnels, and particularly relates to a shield segment waterproof structure and a construction method thereof. The shield segment waterproof structure is characterized in that a circular seam groove is formed in the tail end of a circular seam of a segment, a longitudinal seam groove is formed in the tail end of a longitudinal seam of the segment, and the profiles of the circular seam groove and the longitudinal seam groove are both in swallow-tail shapes; one end of a circular seam sealing strip is a circular seam straight head, the other end of the circular seam sealing strip is a circular seam swallow-tail head matched with the circular seam groove, the circular seam straight head of the circular seam sealing strip is inserted into the circular seam groove of the segment, and the circular seam swallow-tail head of the circular seam sealing strip is inserted into the tail end of the circular seam of the adjacent segment in the axial direction; and one end of a longitudinal seam sealing strip is a longitudinal seam straight head, the other end of the longitudinal seam sealing strip is a longitudinal seam swallow-tail head matched with the longitudinal seam groove, the longitudinal seam straight head of the longitudinal seam sealing strip is inserted into the longitudinal seam groove of the segment, and the longitudinal seam swallow-tail head of the longitudinal seam sealing strip is inserted into the longitudinal seam groove of the adjacent segment in the radial direction.

Description

technical field [0001] The invention belongs to the technical field of shield tunneling, and in particular relates to a shield segment waterproof structure and a construction method thereof. Background technique [0002] With the development of modern urban buildings and transportation public facilities, the urban land resources are becoming more and more tense, and the ground transportation in the city can no longer meet the traffic requirements. In order to save urban land resources and alleviate the pressure of urban public transportation, it is imperative to expand the urban underground space. It is of great significance to build underground transportation facilities such as subways and urban underground highway tunnels. [0003] The shield method is a fully mechanized construction method in the underground excavation method. It propels the shield machine in the ground, and supports the surrounding rock through the shield casing and segments to prevent collapse into the...
