Description
Technical field
The present invention relates to a kind of construction drainage pipeline.
Background technology
Building is people's soil, brick, watt, stone material, timber；（Modern age reinforced concrete, section bar）Constituted Deng construction material
Space that is a kind of for human habitation and using, such as house, bridge, factory building, gymnasium, cave dwelling, water tower, temple etc..Broadly come
Say, landscape, gardens are also wing.Say in a broad sense, the nest that animal is built consciously can also can be regarded as building.Western wise man
There is cloud：Building is the music of solidification, and building is a stone history records.The classical masterpiece of Roman architecture man's Vitruvius《Building
Ten books》Propose three standards of building：It is firm, practical, attractive in appearance, the architectural development of later age is affected always.Building composition
Three elements：Building function, Building technology and art of architecture image.
Pipeline be with pipe, pipe connector and valve etc. be connected into be used for convey gas, liquid or with solid particle
Fluid device.Feedwater, draining, heat supply, the oil transportation of the trunk pipeline given gas and long range in city, feed channel are most
Be laid in underground, and the process pipe in factory is laid on the ground more for ease of Operation and maintenance.The current of pipeline, supporting, slope
Degree and discharge opeing exhaust, compensation, insulation and heating, anti-corrosion and cleaning, identification and japanning and safety etc., no matter for over ground installation also
It is the problem of underground laying is all important.
Pipeline on ground, which should try one's best, to be avoided intersecting with road, railway and navigation channel.When not being avoided that intersection, infall across
Height more should be able to also make pedestrian and car and boat safety.The pipeline of underground is typically laid along road, is kept between various pipelines
Appropriately distance, to install and to repair；There is heat-insulation layer on the surface of heat supply pipeline, is laid in trench or protection pipe, should avoid
Gone bad by soil pressure and move pipe expansion.
Pipeline may bear the effect of many kinds of external force, including thrust of the weight, fluid matasomatism of in pipe end itself, wind and snow
Load, ground pressure, expand with heat and contract with cold caused thermal stress, oscillating load and earthquake disaster etc..In order to ensure pipeline intensity and
Rigidity, it is necessary to set various branch (to hang) frame, such as travel(l)ing rest, fixed support, guiding trestle and spring support.The setting of support
According to conditional decisions such as the diameter of pipeline, material, pipe wall thickness and load.The heat that fixed support is used for Discrete control pipeline is stretched
It is long, make expansion joint uniform operational；Guiding trestle makes pipe only move axially.
The current existing function without fireproof heat insulating, structural stability is not high, and the interior tube layer of use installs inconvenient,
Anticorrosion effect is bad.
