Description
Technical field
The present invention relates to subway work technical fields, and in particular to a kind of concrete construction control method.
Background technology
Subway is a kind of form of railway transportation, refers to the City Rail Transit System based on being run in underground, i.e. " subway
The abbreviation in road " or " subway " (Subway, tube, underground)；Many such systems in order to coordinate the environment of build,
And construction and operation costs are considered, ground or overhead section may be changed into area beyond down town.Subway is to cover
The right of way of the various undergrounds in urban area and ground is proprietary, the City Rail Transit System (Metro) of high density, high freight volume, China
Taiwan subway is referred to as " rapid transit " (Rapid transit).
In addition to subway, the also railway including being laid on overhead railway (Elevated railway) or road surface.Cause
This, subway be right of way it is proprietary, without usual friendship, this is also the mark that subway is different from the essence of Light Rail Transit.In the world
Earliest (and first) subway is big city's subway of London, is established in 1863.
In subway work, concrete casting work also takes up larger proportion, and ten are checked on for the quality of concrete
Divide stringent.Measure check on therefore, it is necessary to making a set of stringent concrete quality and ensures the quality of concrete.
