Abstract

The invention belongs to the technical field of tunnel construction, and particularly relates to a fixing device for a duct piece and a channel. The fixing device comprises the duct piece, the channel and a fixing part; a sleeve is pre-embedded in the duct piece; a plurality of first limiting grooves are formed in the side wall of the channel at intervals; first bolts are arranged in the first limiting grooves; the channel is fixed to the inner wall of the duct piece through the fixing part; one end of the fixing part is in threaded fit with the sleeve; and the other end of the fixing part is fixedly connected with a first bolt. According to the fixing device for the duct piece and the channel, the problems that when the bearing weight of an external channel exceeds the bearing limit, the stability of the structure between duct pieces is damaged, and when the position of the channel is adjusted, disassembly is troublesome, and manpower and material resources are wasted can be solved, and the good market application prospect is achieved.

Description

technical field [0001] The invention belongs to the technical field of tunnel construction, and in particular relates to a fixing device for a segment and a channel. Background technique [0002] The tunnel in the rail transit is a pipeline structure, and the inner wall of the tunnel is spliced ​​by multiple segments, and then a channel is installed on the inner wall of the tunnel to fix the channel on the segment. In the prior art, there are many ways to fix segments and channels, including embedded channels, external channels, and traditional perforated installation. Pre-embedded channel refers to the pre-embedded channel inside the segment when the segment is manufactured. This method is complicated in the process of making the pipe. When replacing the segment and the channel at the same time, the cost is too high, and there are reasons Poor combination of channels and segments leads to water seepage at the joints. The traditional drilling installation method is to dril...
