Description
Technical field
The present invention relates to a kind of underground rail prefabricated pipe section for shield tunnel and preparation method thereof, this prefabricated pipe section for shield tunnel
It is used in particular for the installation of municipal cable in major diameter Underground Rail Transit shield tunnel.
Background technology
With the continuous acceleration of urbanization process, Underground Space Resource increasingly consumes, the applying of traditional buried cable passage
Make difficulty is subject to urban track traffic and other undergrounds municipal pipeline is built impact and increasingly increase.Hand over building underground rail
When logical, by increasing tunnel diameter, it is cable pipeline headspace, while connecting city traffic, ultra-high-tension power transmission line
Accessed and introduction center city by subterranean tunnel, alleviate the difficulty of the power transmission to inner city, you can to save day
The Underground Space Resource being becoming tight, solves a difficult problem for underground line planning during city network is built again, can make municipal administration simultaneously
Electrical network and Construction of Urban Rail Traffic are able to harmony, coordinated development.
At present, it is accomplished by itself in Underground Rail Transit arranging numerous cables, cable is usually to be fixed on shield by support
Support on section of jurisdiction.Generally, the installation of support is all boring on shield duct piece, is then connected with section of jurisdiction through bolt.Due to needing
Shield duct piece is holed, and intensive bar-mat reinforcement has been laid when making in section of jurisdiction, when therefore holing, easily get into bar-mat reinforcement
On, not only affect the quality of section of jurisdiction, cause the infiltration of structure, it is also often desirable to again bore and beat, the boring scrapped in addition needs in time
Filling, causes the waste of unnecessary financial resources, manpower.Compared with the cable required with Underground Rail Transit itself, municipal cable
Diameter is thick, from great, if cable is hung over shield duct piece by way of support is beaten in boring, can cause between section of jurisdiction itself and section of jurisdiction
The deformation further of joint is excessive, leads to tunnel leak.Further, since use during cable covering abrasion, electric current lead to
Cross the reinforced mesh formation potential difference that cable bearer bar flows on shield duct piece, further result in the electrochemical corrosion of section of jurisdiction, shadow
Ring the normal use of structure.
