Abstract

The invention discloses an embedded channel positioning device for subway segments and a method for applying the embedded channel positioning device. The embedded channel positioning device comprisesa first connecting rod, a rotary sleeve and a second connecting rod. The top of the first connecting rod can be detachably connected with a reinforcement cage; the rotary sleeve comprises a rotary shaft, a first sleeve and a second sleeve, the first sleeve is rotationally connected to the top of the rotary shaft, the second sleeve is rotationally connected to a rotation bottom, and the bottom of the first connecting rod is in screw thread fit with the first sleeve; the bottom of the second connecting rod is fixedly connected to an embedded channel, and the top of the second connecting rod is in screw thread fit with the second sleeve. The method includes tightening and matching the first connecting rod and the first sleeve with each other and tightening and matching the second connecting rod and the second sleeve with each other; hoisting the embedded channel positioning device and the embedded channel to predetermined locations in subway segment pouring molds; connecting the first connecting rod and the reinforcement cage with each other; loosening the first connecting rod and the first sleeve until the bottom surface of the embedded channel tightly clings to the inner bottom surfaces of the molds so as to completely position the embedded channel. The embedded channel positioning device and the method have the advantages that the embedded channel positioning device is simple in structure, good positioning effects can be realized, and the integrity of the embedded channel can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of channels, in particular to a pre-embedded channel positioning device for a subway segment and a using method. Background technique [0002] In modern reinforced concrete engineering, embedded parts are widely used in rail transit, high-speed rail, buildings and other occasions. During the construction, the pre-buried channel is prefabricated in the concrete of the building. In order to ensure that the channel does not change its original position when the concrete is poured, at this stage, a hole is drilled at the fixed position of the channel as the positioning hole, and the positioning hose is passed through the positioning hole. The holes are inserted into the channel to locate and fix the channel. However, in the process of pouring concrete, the cement slurry will flow into the channel through the positioning hole to block the channel, which will affect the normal use of the channel. For this reason...
