Abstract

The invention discloses a tunnel lining segment ring, a construction method and a tunnel lining. A glue-injectable water-stop sealing pad is provided on the circumferential joint surface of the tunnel lining segment ring. The glue-injectable water-stop sealing pad includes rubber The main body is provided with a glue injection channel in the rubber body, which is used to inject hot-melt water-stop glue; a hot-melt coil is provided inside the glue injection channel, and reservations are made on both sides of the rubber injection channel to ensure that the rubber body can be compressed The reserved channel is provided with an expansion water-absorbing layer on the outside of the rubber body; and the rubber body is also provided with a grouting hole connected with the injection channel; the tunnel lining segment ring is provided with an injection hole, and the injection hole passes through the tube located in the tube. The glue injection pipe in the sheet communicates with the glue injection channel. After the segment is assembled and installed, hot-melt water-stop glue is injected to strengthen the sealing and water-proof performance of the segment joint; when the segment leaks water during operation, the hot-melt coil is energized, the water-stop glue is melted, and a second injection is performed. Glue, secondary reinforcement of segment seam sealing performance.

Description

technical field [0001] The invention belongs to the field of rail transit engineering, and in particular relates to a tunnel lining segment ring, a construction method, and a tunnel lining. Background technique [0002] At present, most of the segment leakage occurs at the joints of the segments. The gaps between the segments are uneven, and the local gaps are too large, so that the sealing strip cannot meet the requirements; It is loose or deformed during splicing, thus losing the sealing effect, which greatly affects the sealing effect of the gasket. [0003] After the construction of the tunnel is completed, groundwater will also seep into the tunnel due to gaps between segments due to settlement, vibration or uneven force, which will adversely affect the use and safety of the tunnel. It is difficult to treat the segment after water leakage. The treatment process often needs to destroy the structure of the segment and inject glue to stop the water. It will be more diffic...
