昨天,嘉城集团天然气管网公司工作人员来到南湖区市域天然气高压管网工程沿线进行土地放样、核对施工图纸,“目前工程建设的前期准备进入尾声,正在进行土地放样和拆迁、借地补偿等扫尾工作,本月底将进场施工”。据嘉城集团天然气管网公司负责人介绍,明年年底工程建成后,管输天然气将覆盖“大嘉兴”范围,所有县(市、区)居民均将能用上天然气。

  引入天然气优化能源结构

  天然气是一种优质、高效、清洁的能源,对于优化能源结构具有重要作用。自2000年国家实施“西气东输”工程以来,市政府就根据我省“西气东输”工程建设的统一部署,着手开展一系列准备工作,编制天然气利用规划,建设市区配套燃气管网和场站,实现城市规划区燃气管网的全覆盖。

  根据国家和我省天然气利用规划,嘉兴共接纳四川气源、新疆气源(西气一线)和中亚气源(西气二线)3个天然气气源,其中进入嘉兴主动脉的新疆气源——德嘉线已于去年年底建成并向市民供气。

  为了将管输天然气覆盖至嘉兴市域的各县(市、区),市政府把市域天然气高压管网工程定为今年的民生工程。全长约62公里的市域天然气主干线管道将途经秀洲区、南湖区至嘉善县、平湖市、海盐县、嘉兴港区。管道直径508毫米,设计输气规模约15亿立方米/年,沿线设大桥、嘉善、平湖和海盐4座分输站,还将建设嘉兴南、新丰分输阀室,总用地30.64亩,投资概算3.38亿元。

  节日加班创造施工条件

  昨天上午,在南湖区新丰镇横港村,嘉城集团天然气管网公司工程科的胡鹏飞正在为市域天然气高压管网工程建设放样,“放样就是确定施工作业带范围”。胡鹏飞告诉记者,市域天然气高压管网工程作业带宽度为15米,其中一边是10米,供挖掘机施工;另一边是5米,用作堆放土方。“国庆长假前4天,大家轮流加班,10月5日开始,大家都提前上班了。”

  与胡鹏飞同样忙碌的还有他的同伴们,同在工程科的金亦飞昨天的任务是核对施工图纸。“到施工现场一段一段地核对管网每一处的施工图纸。”据金亦飞介绍,如果发现施工图纸与现场情况不完全吻合,就需要修改。“铺装的管道直径有508毫米,有的地方运输车辆无法到达,这就需要提前准备好驳运的船只,有的地方没有道路还要修筑施工便道。”

  嘉城集团天然气管网公司负责人告诉记者,现在,工程可行性研究报告编制和项目测绘已经完成,主管网线路走向和场站规划选址通过审批;6个场站规划选址用地完成申报,项目建设环境评估、水土保持、安全预评估等报告也已就绪。此外,施工单位招标及钢管、流量计、进口阀门等大部分材料设备采购的招投标工作也已完成。“国庆长假期间,我们对施工单位的施工方案进行了审查,等管道沿线的晚稻收割后即可动工建设。”

  市域内居民都能用上天然气

  “市域天然气管网工程建成后,能将管输天然气的供应从嘉兴市区扩展到各县(市、区),在市域范围向居民供应管输天然气。”嘉城集团天然气管网公司负责人说,德嘉线通气后,每天有30万立方米新疆优质天然气通过德嘉线进入嘉兴,市区8.9万户居民、桐乡2万多户居民及部分公建单位、大型企业用上了高效清洁的天然气。
 

 

 

 

 

Yesterday, the Kerry Group, the city gas pipeline company personnel in South Lake District, Metropolitan Area high pressure natural gas pipeline network project of land along the loft, check the construction drawings, "At present, preparation of project construction drawing to a close, ongoing land-lofting and demolition compensation Jiede and so off the work end of this month will be entering the construction. " According to Kerry Group, the city's natural gas pipeline network person in charge of next year by the end of the project is completed, the pipeline gas will cover the "big Jiaxing" scope, all counties (cities, districts) residents would use natural gas.

The introduction of natural gas to optimize energy structure

Natural gas is a high quality, efficient, clean energy, optimizing energy structure has an important role. Since 2000, the national implementation of the "Natural Gas" project since the city government under our province, "Natural Gas" project of the unified plan, initiated a series of preparatory work, the preparation of natural gas use planning, construction of urban gas pipe network supporting and field stations, to achieve urban planning area covers the entire gas pipeline network.

Natural gas, according to national and province-use planning, Jiaxing accepted for gas supply in Sichuan, Xinjiang gas source (West gas line) and the Central Asian gas sources (second-tier Western Gas) 3 gas gas source, which enter the gas source in Xinjiang Jiaxing aorta -- - Noriyoshi line was completed late last year gas supply to the public.

In order to cover the natural gas pipeline to the domain Jiaxing counties (cities, districts), the municipal government the city of high pressure natural gas pipeline network domain works are scheduled for this year's livelihood project. Total length of about 62 kilometers of the city, the domain of natural gas trunk pipeline will pass through Xiuzhou District, South Lake District to Jiashan County, Pinghu City, Haiyan County, Jiaxing port. Pipe diameter of 508 millimeters, the size of the design is about 1.5 billion cubic meters gas transmission / year, located along the bridge, Jiashan, Pinghu, and sea salt 4 points lost stations, will also build Jiaxing South, Xinfeng sub-transmission valve chambers, with a total land 30.64 mu, Investment estimates 338 million.

Construction of holiday overtime to create the conditions

Yesterday morning, in the South Lake District, xinfengzhen Wang Hong Kong Village, Kerry Group, the city's natural gas pipeline network engineering for the city, the domain of the Peng-Fei Hu is high pressure natural gas pipeline network construction lofting, "lofting is to determine the scope of the construction work zone." Peng-Fei Hu told reporters, city high pressure natural gas pipe network engineering field operations width of 15 meters, one side is 10 meters for the excavator construction; on the other side is 5 meters, used as a stack earthwork. "4 days before the National Day holiday, we take turns overtime, October 5 beginning, we have work ahead of time of."

Equally busy with the Peng-Fei Hu and his companions, with the gold in the Engineering Section is also flying yesterday's task is to check the construction drawings. "To the construction site section by section to check the pipe network construction drawings everywhere." According to Kim Yi-fei presentations, construction drawings and on-site if they are not fully fit, we need to modify. "Paving the pipe diameter of 508 mm in some areas, transport vehicles can not be reached, which requires advance ready for lightering vessels, but also in some places there is no road pavement construction works."

Kerry Group, the city gas pipeline network company told reporters, and now, engineering feasibility study report and project mapping has been completed, in charge of network alignments and station planning and site selection through the examination and approval; 6 space station planning and site selection to complete a declaration project environmental assessment, soil and water conservation, safety pre-assessment report is ready. In addition, the construction unit tender and steel pipes, flow meters, valves, and most other imported materials and equipment procurement bidding work has been completed. "National Day holiday period, we have the construction plan of the construction units were reviewed, and so on along the pipeline to start construction immediately after the harvest of late rice."

City area residents can spend gas

"Urban Field natural gas pipeline network project is completed, can the supply of natural gas pipeline from the Jiaxing city extended to the counties (cities, districts), in the city of domain-wide supply of pipeline gas to the residents." Ka City Group natural gas pipeline company said , Noriyoshi line of ventilation, the 300,000 cubic meters per day of natural gas in Xinjiang by Noriyoshi line of high-quality access to Jiaxing, 89000 urban residents, Tongxiang more than 20,000 households and some of the public construction units, and large enterprises were using clean and efficient natural gas.
