Research Of Environmental Supervision Project Of Chengdu-Chongqing Railway Line For Passenger Traffic

Railway is the important national infrastructure with long line and many points, the pollution of the environment can not be ignored. At present, China’s railway construction project environmental management system in project feasibility study stage is mainly embodied in the environmental impact assessment system, in the operation period is mainly embodied in the "three simultaneous " system and environmental evaluation system. And the railway construction ecological environment influence began in exploration, line selection, occur in construction period, at the completion of inspection, ecological damage and other environmental effects have already occurred, irreversible.Environmental supervision to the environmental impact assessment system, the "three simultaneous" system and environmental evaluation system of organic com, formation of the railway construction project construction period, operation period environmental protection effective supervision system.Passenger designed for " comprehensive transport network and long-term development planning " in the "five vertical and five horizontal " comprehensive transportation channel of " along the Yangtze River to carry big channel " main component, belonging to the railway ministry " in long-term railroad network plans (2008Revision)" in "4vertical four horizontal strokes " passenger part of passenger dedicated line. The PDL for doublet, electric traction, the design speed of250km/h. Total line length of308.206km (operation length of309.224km).This paper mainly from the environment through the supervision of meaning extension, clear environmental supervision characteristics, determine the environmental supervision on the basis of the work, working content, scope of work and work procedures, supervision mechanism and form of environmental supervision in construction period of points, combined with the railway construction project environmental pollution characteristics, Research the environmental supervision project of Chengdu-Chongqing Railway Line for passenger traffic. According to the project direction and composition, define the scope of Environmental Supervision:railway passenger dedicated line engineering construction range (i.e., the main line DKO+000-DK306+302.2) the main part of the project, temporary engineering (construction camp, road construction, discarded soil field, system (DPS) beam field, the prefabricated plant, mixing the station, the track base, quarry and storage etc.) construction site and need special protection, environmental sensitive area of Forest Park in Linghai and Trinity Trinity Linghai4A grade scenic spot, Longquan Huaguo Mountain Scenic Area, scenic areas of Geleshan and the Forest Park in Leshan, County Ejiang Yinshan town of centralized drinking water source protection area of subject; Based on the Passenger Dedicated Railway environmental impact report and environmental impact assessment, soil and water conservation scheme approved environmental and approval, the design scheme of protective measures as the basis, explicit the environmental supervision of compliance supervision content and environmental engineering construction supervision content; adopt three level supervision system the general supervision engineer is responsible for the establishment of the environment, the project supervision department at City, A aera and B aera supervision site set up in supervision group and supervision group; the supervision period is divided into the preparation stage, construction stage and completion of trial operation period, and to develop environmental supervision procedures. By the work period, the supervision groups constitute the process program, working system, measures and quality control methods to ensure quality supervision, to ensure that the regulatory role in environmental protection work of project construction period of, also provide a reference for implementation of railway construction project environmental supervision in future.
