Case Analysis On Green Construction Of Urban Rail Transit Project

With the development of cities in China,urban rail transit projects will play an increasingly important role in transportation.At present,in addition to Beijing,Shanghai,Guangzhou,Shenzhen and other cities with more mature urban rail transit network,other cities are still in the initial stage of construction.Because of the one-sided pursuit of construction progress,the phenomenon of waste of resources and environmental damage is common.This paper introduces the definition of green construction,the development background and the status quo at home and abroad around the urban rail transit project,and analyzes the existing problems in the green construction of urban rail transit project.First,at present,the laws and regulations and standards for green construction in urban rail transit are still not sound,the government level of law enforcement measures need to be improved,and the enforcement of law needs to be strengthened.Second,the responsibility main body of the construction parties and the people's consciousness of saving resources and environmental protection are not deep enough,and the understanding of green construction of urban rail transit project is insufficient.Third,the construction unit's unreasonable arrangement of materials and machinery,the definition of green materials is not clear,and material control is lax,resulting in waste of resources.Fourth,in the process of construction,the low energy consumption and high efficiency of green machinery are seldom used,and the traditional construction technology is generally adopted,which brings about the waste of resources and the rise of pollutants.Therefore,the implementation of green construction in urban rail transit construction is of great significance.In this paper,3 cases are analyzed,Shenzhen urban rail transit project line 6 uses solar collector plate and the recycle system of rainwater and waste water to achieve energy saving and water saving,Shenzhen urban rail transit project line 11 uses reinforcement centralized distribution center and other measures to achieve land saving and material saving,and Beijing Metro Line 8 using fully enclosed shaft workshop and other measures to achieve environmental protection.The existing problems,solutions and achievements of energy saving,water saving,land saving,material saving and environmental protection in the construction process of urban rail transit project are analyzed.It will provide reference for improving the level of green workers and promoting the sustainable development of urban rail transit projects.
