Technical field
This utility model is related to a kind of supply and drain water system, more particularly to a kind of extremely frigid zones subway supply and drain water system.
Background technology
Since reform and opening-up, each urban economy of China is achieved and is developed faster, possesses certain Economic Energy in each big city
The puzzlement of urban transportation is received while power, and downtown area aboveground space resource is nervous, and Urban New District is apart from midtown
Farther out, have inconvenient traffic, in order to alleviate urban traffic pressure, solve Urban Traffic Jam Based, many cities are Development of Urban rail
Road traffic is used as the first-selection for solving urban traffic blocking.As what state-owned railroads were built extends to Inner Mongol, northwest, southwestward,
These regional cities certainly will occur traffic pressure also in fast development, in order to prevent these Urban Traffic Jam Baseds,
The construction of the City Rail Transit System " subway " based on the operation of underground is unavoidable.
The subway construction of China history of nearly 50 years, has a very abundant orbit construction experience, but
The subway construction of extremely frigid zones also quantity is very few, and the first extremely frigid zones subway system of China is Harbin subway, and it is from 2016
Year start to open test operation, up to now also just time of 3 years or so, subway had once gone through subzero 33 degrees Celsius since opening operation
The lowest temperature test, also once there is the water pipe freeze injury accident in the supply and drain water system of part, the safety of supply and drain water system is concerned
The normal operation of subway, concerns passenger survival and national wealth safety, needs to prevent these extremely frigid zones subway plumbing in advance
Occurs freeze injury problem in system.
Utility model content
The purpose of this utility model is to provide obvious, the safe and reliable one kind of a kind of high insulating effect, anti seismic efficiency
Extremely frigid zones subway supply and drain water system.
To achieve these goals, the technical solution of the utility model is：
A kind of extremely frigid zones subway supply and drain water system, including water supply system, drainage system and fire-fighting system, described feedwater
Aqueduct in system and drainage system is cylinder, and described aqueduct opens up a V-groove, water-supply-pipe from top to bottom
Road is ductile iron pipe, is arranged with heat-insulation layer outside aqueduct, and described heat-insulation layer is blanket of glass wool, is coated outside heat-insulation layer
Reflective insulation aluminium foil layer, is provided with rigid polyurethane foams layer, described rigid polyurethane foams outside described reflective insulation aluminium foil layer
Layer surrounding is evenly distributed with projection centered on the center of circle of aqueduct, and described projection is trapezoidal projection, described projection
Quantity at least 4, arranges carbon dioxide layer between described reflective insulation aluminium foil layer and rigid polyurethane foams layer, described is hard poly-
Overcoat is arranged with outside urethane froth bed, and described overcoat is rubber.
Further, phenolic resin corrosion-resistant coating is scribbled outside described aqueduct.
Further, described water supply system includes water tank, water pump, pond and aqueduct, described pond, water pump according to
It is secondary that water tank is connected to by aqueduct.
Further, described drainage system mainly includes：Sewerage, waste water system, storm-water system, between each system
Drainage pipeline networks is sequentially connected to by aqueduct.
Further, described heat-insulation layer, carbon dioxide layer, rigid polyurethane foams layer, the thickness of overcoat are 40mm.
This utility model is a kind of extremely frigid zones subway supply and drain water system, and its advantage is：
In this utility model, aqueduct is set to cylinder, and aqueduct opens up a V-groove from top to bottom and allows same
If time inflow is identical, the flow velocity of water faster, facilitates the demand of emergency water in subway station；Aqueduct peripheral hardware is arranged with
Heat-insulation layer of the super glass wool for material, because super glass wool has, heat conductivity is little, absorptance is big, fire resistance good
Various advantages, this allows for the aqueduct protected by super glass wool and has a more preferable heat insulation effect, and its have it is stronger
Fire resistance, has been greatly reduced because fire causes the probability of the paralysis of subway supply and drain water system, the outside painting of heat-insulation layer
Reflective insulation aluminium foil layer is used for allowing the partial heat that can be shed in aqueduct to be reflected back in aqueduct, enhances subway discharge
The heat-insulating property of water system, the rigid polyurethane foams layer outside heat-insulation layer also have that insulation effect is good, lightweight, intensity big, apply
Work is convenient, enhances the heat insulation effect of aqueduct, and rigid polyurethane foams layer inside circumference is centered on the center of circle of aqueduct
Equally distributed trapezoidal projection can be stored in heat energy in adjacent trapezoidal raised gap, reflective insulation aluminium foil and rigid polyurethane
The carbon dioxide layer of froth bed middle setting is because the greenhouse effect of carbon dioxide also further enhancing the insulation of aqueduct
Effect, overcoat are rubber, enhance heat insulation effect and the anti-seismic performance of aqueduct, in extremely frigid zones subway supply and drain water system
The generation of aqueduct freeze thawing phenomenon is above all prevented, is processed by our this insulation means, is realized in extremely frigid zones
Feedwater is unobstructed, it is to avoid the problem that domestic water all standing, fire demand water can not be supplied in time.
