Description
Technical field
The invention belongs to pipeline placement technique fields, more particularly, to a kind of administrative region of a city railway arrangement structure for pipelines and side
Method.
Background technique
The laying type of pipeline has very much, is divided into two kinds according to pipelining mode, one is surfaces: conducting wire is directly in pipe
In the protectives such as son, wire casing, it is laid in wall, the surface of ceiling and truss, bracket etc..Applied one is dark: conducting wire pipe,
In the protectives such as wire casing, it is laid in the inside such as wall, ceiling, terrace and floor, or wiring etc. in concrete plate hole.
Most common of them is buried-pipe laying, and buried-pipe laying is divided into directly buried installation and in-duct installation.Wherein by pipeline
Mode on the wall of the independent rack, truss and the building that are laid on ground is exactly aerial laying, is had convenient for applying
Work, operation, inspection, maintenance and it is economical the advantages that；Directly buried installation is a kind of system of laying that pipeline is directly buried, its advantage is that
Using the space of underground, keep the above space in ground more succinct, and is not required to bearing measure；In-duct installation is by pipeline laying in ground
In trench made of concrete or masonry bond under face, the underground space can be made full use of, and provide and more conveniently check
Maintenance condition can also lay the pipeline of the high temperature of thermal insulation layer, easy coagulation medium or corrosive media.The disadvantage is that costly, land occupation
Area is big, need to set drainage point, easily gathers or seal in oil gas, increases insecurity factor, and dirt clears up difficulty etc..Various system of laying
There is the respective scope of application.And in the prior art, the pipelining in a workshop, a factory or even a regional scope
A kind of pipelining mode is mostly used to be radiated.
Buried-pipe laying and in-duct installation are most traditional most common pipelining mode, but the location softer in soil property, are passed
There are many defects for the in-duct installation mode of system；On the one hand, traditional laying because of shock and vibration and can be built in use
It builds the effect of the extraneous stress such as the flexible of object, sedimentation and destroys and lay the line, to cause pipe trench basic in actual use
It is deposited in mud；On the other hand, the pipeline of laying is divided into forceful electric power, light current, and two kinds of cross pipe-lines will appear interference, in addition manage
Ditch sedimentation can aggravate the interference between strong and weak two kinds of pipelines.In addition to this, traditional single pipelining mode, in landform, sets
The different sections for applying the factors such as function, pipeline type are less applicable in, and single system of laying will increase pipelining difficulty, are increased
Cost increases repair and maintenance expense.
Summary of the invention
Aiming at the above defects or improvement requirements of the prior art, the present invention provides a kind of administrative region of a city railway arrangement structure for pipelines,
Gantry is set up using the existing structure for support in the soft location of soil property, pipeline is placed in gantry, is avoided because of punching
It hits, vibrate and the extraneous stress effects such as the flexible of building, sedimentation cause pipe trench foundation settlement into mud；Gantry, which divides two layers, to be set
It sets, is respectively used to place forceful electric power pipeline and light current pipeline, prevents two kinds of cross pipe-lines from interfering；Grid is set in gantry, no
Same pipeline is placed in different grids, and different pipelines is kept apart, mutual interference, while easy access are avoided
And maintenance；It is configured by the way of buried-pipe laying crossing rail location, to adapt to the pipelining of different section.
To achieve the goals above, as one aspect of the present invention, a kind of administrative region of a city railway arrangement structure for pipelines is provided, is wrapped
