Background technique
With the rapid development of our country's economy, in order to solve the resource of each big-and-middle urban traffic blocking and aboveground space
Anxiety, subway construction are increasingly taken seriously.
Although China's subway construction has had longer history, there are construction experiences abundant, however in the subway of extremely frigid zones
Quantity is less, and when the subway supply and drain water system of the prior art is used for extremely frigid zones, happen occasionally water pipe freeze injury accident, influences
The safety of subway supply and drain water system, it is directly closely bound up with subway normal operation, once occur major accident, passenger survival and
National wealth is unable to get safely guarantee.
The water pipe general structure of the subway supply and drain water system of the prior art is simple, and heat insulating ability is poor, is not suitable for extremely frigid zones
It is used in subway, it is sometimes desirable to which additional setting heating device just can guarantee the normal operation of supply and drain water system, and energy consumption is higher, not ring
It protects, in addition, the water pipe of the subway supply and drain water system of the prior art is easy blocking, equally will affect the normal fortune of supply and drain water system
Row.
Utility model content
The utility model proposes extremely frigid zones environment-friendly type subway supply and drain water system, purpose is intended to overcome the prior art
Above shortcomings are realized the heat insulation effect for improving supply and drain water system, and are not easy to plug, and guarantee safe and reliable.
The technical solution of the utility model: extremely frigid zones environment-friendly type subway supply and drain water system, structure includes water supply
System, sewerage, waste water system and storm-water system, wherein water supply system includes water feeder and water tank, water feeder and water storage
It is connected between case by aqueduct, water pump, sewerage, waste water system is set on the aqueduct between water feeder and water tank
Pass through individual aqueduct respectively with storm-water system and connect drainage pipeline networks, aqueduct be followed successively by from inside to outside TPEP steel pipe,
Insulating layer, thermal insulation layer, polyurethane foam and flame retardant rubber layer, TPEP steel pipe inner top and interior bottom are uniformly provided with several gears
Block.
Preferably, the adjacent block is staggered up and down, and the section of block is right angled triangle.
Preferably, the insulating layer is mineral wool carpet veneer.
Preferably, the thermal insulation layer is aluminium foil layer.
Preferably, several cavitys are evenly equipped on the polyurethane foam lateral surface, set fire retardant in cavity.
The advantages of the utility model: structure is simple and effective, in the water supply system in supply and drain water system and sewerage,
Between waste water system and storm-water system and drainage pipeline networks, Water delivery pipe line, Water delivery pipe line innermost layer TPEP steel are used
Pipe can be effectively corrosion-resistant and less scaling, has self-cleaning function, blanket of glass wool insulating layer, aluminium foil thermal insulation layer and polyurethane foam
Layer multiple tracks insulation construction can effectively improve pipe insulation effect, guarantee that the plumbing of extremely frigid zones subway supply and drain water system is unobstructed,
No setting is required heating device, energy-saving and emission-reduction are environmentally protective, and the block being arranged in pipeline can make water generate the flowing of multi-angle, from
It moves to being washed away in pipeline, is not easy to accumulate dirt, be not easy to plug, and pipeline is light-weight, be easy to construct, and can effectively prevent fire
Influence of the disasters such as calamity to supply and drain water system, is very suitable for promoting the use of.
