Problems solved by technology

[0002] At present, a large number of pre-buried channels are used in most subways and urban comprehensive pipe corridors in my country. The pre-buried channels are mainly used to install and protect the electromechanical systems such as cables and pipes required in the tunnel. Most of them are pre-buried in concrete and cannot be replaced later. After a long period of use, the pre-buried channel may be damaged due to damage or decay, which will affect the protection of cables and pipes

Abstract

The invention discloses a pre-buried sleeve used for channel installation and a channel positioning method, and belongs to the technical field of building construction. The pre-buried sleeve used forchannel installation comprises a sleeve body and a positioning part, a pan head is arranged at one end of the sleeve body, and a threaded hole is formed in the other end of the sleeve body; a screw rod corresponding to the threaded hole is arranged at one end of the positioning part, and a positioning pillar is arranged at the other end of the positioning part. In the channel positioning method, apre-buried sleeve used for channel installation, a concrete pouring formwork with one or more positioning holes and a channel with one or more installing holes are involved. The positioning part is connected with the sleeve body, the pre-buried sleeve used for channel installation is fixed to the concrete pouring formwork through the positioning holes, concrete is poured onto the concrete pouringformwork, and the positioning part and the sleeve body are separated after the concrete is solidified to connect the channel with the pre-buried sleeve used for channel installation through the installing holes. With the channel positioning method, the channel can be conveniently and rapidly installed and replaced.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a pre-embedded sleeve for channel installation and a channel positioning method thereof. Background technique [0002] At present, a large number of pre-buried channels are used in most subways and urban comprehensive pipe corridors in my country. The pre-buried channels are mainly used to install and protect the electromechanical systems such as cables and pipes required in the tunnel. Most of them are pre-buried in concrete and cannot be replaced later. After a long period of use, the pre-buried channel may be damaged due to damage or decay, which will affect the protection of cables and pipes. [0003] Therefore, there is a need for a device for installing and replacing channels conveniently, quickly and efficiently to meet the usage requirements. Contents of the invention [0004] The purpose of the present invention is to provide a pre-embedded sleeve for cha...
