Abstract

The invention discloses a tunnel lining segment ring, a construction method and a tunnel lining. According to the tunnel lining segment ring, a glue-injectable water-stop sealing gasket is arranged onthe circumferential joint surface of the tunnel lining segment ring, the glue-injectable water-stop sealing gasket comprises a rubber main body, a glue injection hole channel is formed in the rubbermain body, the glue injection hole channel is used for injecting hot melt water-stop glue, a hot melting coil is arranged in the glue injection hole channel, reserved hole channels for guaranteeing compressibility of the rubber main body are reserved in the two sides of the glue injection hole channel, an expansion water absorption layer is arranged on the outer side of the rubber main body, the rubber main body is further provided with guniting holes communicating with the glue injection hole channel, and glue injection holes are formed in the tunnel lining segment ring and communicate with the glue injection hole channel through glue injection pipes located in segments. After the segments are assembled and installed, hot melt water stop glue is injected to enhance the sealing and water stop performance of segment joints, when water leakage occurs in the operation period of the segments, the hot melting coil is powered on, the water stop glue is melted, secondary glue injection is conducted, and the sealing water stop performance of the segments joint is enhanced for the second time.

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 leakage of segment occurs at the segment joints. The gaps between 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 the 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 leakage of the segment, and the treatment process often needs to destroy the structure of the segment for needle-tube glue injection to stop the water. It will be mo...
