Application and advantage of steel pipe in construction of underground integrated pipe corridor

With the acceleration of urbanization,the construction of underground integrated pipe corridor has become an important part of modern urban infrastructure.The underground integrated pipeline corridor can centrally arrange all kinds of pipelines,solve the problem of efficient utilization of urban underground space,and reduce the land occupation and environmental damage of traditional pipeline laying methods.In the construction of pipe corridors,steel pipe,as an important basic material,has unique advantages and is widely used in the construction of various pipe corridors.

I.Overview of underground integrated pipe gallery

The underground integrated pipeline corridor is a facility that arranges various urban pipelines(such as power,telecommunications,water supply,gas supply,etc.)in the underground space in an intensive and three-dimensional way.Through unified planning,design and construction,it can not only improve the utilization rate of underground space,but also reduce the difficulty of pipeline maintenance and environmental risks.With the increase of urban underground space demand,the construction of pipe corridor has gradually become the best solution to the problem of"insufficient ground space"in the city.

Second,the important role of steel pipe in the underground integrated pipe gallery

Because of its excellent physical properties and corrosion resistance,steel pipe has become one of the commonly used pipeline materials in the construction of underground integrated pipe gallery.It can not only withstand high pressure,high temperature and chemical corrosion,but also has good mechanical strength and seismic performance,especially suitable for use in complex underground environments.Specifically,the application of steel pipes in underground integrated pipe galleries is as follows:

Power and communication pipes:In the underground integrated pipe gallery,steel pipes are widely used for the protection of power cables and communication cables.Steel pipes can effectively protect cables from external shocks and corrosion,ensuring the long-term stable operation of power and communication systems.

Water supply and drainage pipes:steel pipes are also widely used in water supply pipe networks and drainage systems.Its pressure resistance and corrosion resistance make the steel pipe in the long-term use process,to ensure that the water quality is not polluted,reduce the maintenance and replacement frequency.

Gas supply pipeline:steel pipe is widely used in natural gas,gas and other gas transmission system.Steel pipe can effectively prevent pipeline leakage and ensure the safety of gas transportation.

Hvac pipes:Steel pipes can also be used for hot water pipes and steam pipes in HVAC systems.Because the steel pipe has good thermal stability,it can adapt to the high temperature environment and ensure the stable operation of the system.

Third,the advantages of steel pipes in underground integrated pipe corridors

As a commonly used pipeline material,steel pipe has become the preferred material in the construction of underground integrated pipe gallery by virtue of its multiple advantages.The following are the main advantages of steel pipes in this field:

Strong corrosion resistance:the steel pipe has strong corrosion resistance,especially the specially treated steel pipe,which can work stably in the corrosive underground environment for a long time to avoid the problem of pipeline rust and leakage.

High strength and high pressure resistance:The high strength of the steel pipe makes it able to withstand extremely high internal and external pressure,which is suitable for pipeline systems with high pressure requirements in underground environments.Whether it is a water supply pipeline or a gas pipeline,steel pipes can be used safely under high pressure conditions.

Earthquake resistance and impact resistance:the underground integrated pipe gallery usually faces external shocks such as earthquake and traffic vibration,and the steel pipe can effectively resist external shocks and vibrations due to its superior toughness and impact resistance to ensure the safe operation of the pipeline system.

Strong plasticity:The steel pipe has high plasticity and can be processed in different shapes according to needs to adapt to the complex pipe corridor structure requirements.In addition,the steel pipe can also be heat treated or coated to further improve its adaptability and service life.

Environmental protection:Steel pipe is an environmentally friendly material,can be recycled,in line with the requirements of sustainable development.The use of steel pipes in the construction of pipe corridors can not only meet the technical needs of pipeline construction,but also conform to the concept of green building.

Fourth,the construction requirements of steel pipes in underground integrated pipe galleries

In the underground integrated pipe gallery,the construction and installation of the steel pipe should be carried out in strict accordance with the design requirements and construction specifications to ensure the safety and reliability of the pipeline.The following are several aspects that need special attention in the construction process of steel pipes:

Pipeline pretreatment and anti-corrosion treatment:steel pipes need to be treated with anti-corrosion before use to improve their corrosion resistance.Common anti-corrosion methods include coating,anti-corrosion film and so on.Anti-corrosion treatment can not only extend the service life of the steel pipe,but also reduce maintenance costs.

Welding technology:The connection of steel pipes is usually welded.During the welding process,it is necessary to ensure the strength and tightness of the welded joints to avoid problems such as water leakage and air leakage caused by improper welding.

Pipe installation:When installing steel pipes,ensure that the pipes are correctly positioned to avoid pipe bending or deformation.The support and fixing of pipeline is also the key to ensure the stability of pipeline.

Testing and maintenance:The steel pipe after installation needs to undergo strict pressure testing,leak testing,etc.,to ensure its safety.Regular inspection and maintenance are also key to maintaining long-term stable operation of the pipeline.

V.Conclusion

In the construction of underground integrated pipe gallery,steel pipe has become an indispensable material in the construction of pipe gallery by virtue of its excellent performance and multiple advantages.Whether in power,communication,water supply,gas supply or HVAC systems,steel pipes can provide a strong guarantee to ensure the long-term stable operation of the pipeline system.In the future construction of underground integrated pipe corridors,steel pipes will continue to play an important role in promoting urban infrastructure construction to a higher level of development.

Through reasonable construction and installation,combined with advanced technology and management methods,the application of steel pipes will play a greater potential in the underground integrated pipe gallery and help the sustainable development of urban infrastructure.
