With domestic international market and technology big environment of changes, as China traditional industry of pig production of job way and profit way are requirements related industry for resources integration, to quality security for premise, regulation based farming, and management cost and the production, and sales cost, go standardization, and scale, and intensive, and market road, fast upgrade whole industry chain of regulation capacity, market competition capacity and anti-risk capacity. First, industry analysis (a) the basic situation in China is a traditional hog production and consumption country, 2008 46.15 million tons of pork, pig stock 462.64 million head by the end pig slaughter 609.6 million. National pig industrys annual production value at around 650 billion yuan, nearly 50% per cent of annual output value of animal husbandry. Sichuan province in 2008 produced 6.52 million tons of pork, with 694,000 tons of Chengdu city, live pig sell 10.46 million, first 15 Vice-provincial cities in the country. The whole nation advantage regional planning (2008-2015) there are 437 counties (cities), 55, Sichuan, Chengdu has 7 (including in pengzhou). International pig industry mainly include the European Union, the United States, and Canada, and Brazil and other absolute scale of animal husbandry industry and technology developed countries. Market 1, the domestic market from Chinas meat consumption habits and economic analysis of the development situation, the emergence of new trends in the market of domestic pork and its products. Docking is a pig production and sales more closely. The Yangtze River Delta, Pearl River Delta and the Bohai rim economic developed area industrial structure adjustment gathered pace, two or three industries to the Central and Western bias. Second, the rigid domestic consumption growth. For a long period, pork is still the largest variety of meat consumption in China, the absolute consumption continues to grow. Especially in the vast rural market growth potential. Third, market for pork and higher product quality requirements. Pollution-free pork safety and health has shown a very good market prospects. Four is the market changing. Currently, cold meat, more and more varieties of meat and pork meat products, which accounted for a large proportion of pork consumption, stores, chain stores, supermarkets and other marketing methods is on the rise, and transport has been extended to more than 2000 km in RADIUS. Chengdu is an important River pig resource market, the citys commercial rate reaches above 60% of live pigs, pork and raw materials primary processing products in the domestic and international reputation is high. Western hog trading center in Chengdu and provides disease-free areas of construction in order to further accelerate the development of swine industry realizes space and conditions. 2, the international markets at present, annual volume of trade in live pigs in the world year around 18 million, about 6 million tons of pork trade. A large net exporter of pork is mainly the EU and North America,-importing countries mainly in Asia, Japan, and Korea, and Singapore, the Philippines, Hong Kong and other countries and regions, as well as Russia, about 3 million tonnes were imported. It is predicted that the world meat consumption increase of 80% in Asia in the future, our country has obvious geographical advantages, export potential. With the advancement of live pigs superiority industry belt construction, animal disease .外环河综合治理工程（河道及阻水建筑物部分）施工第2标段北丰产倒虹吸施工方案编制：审核：批准：外环河综合治理工程（河道及阻水建筑物部分）施工（第2标段）项目部2015年7月目录第一章 工程概况1一、工程概况1二、编制依据1第二章 工程质量目标2第三章 主要工序及工期安排2一、施工工艺流程2二、施工期安排2第四章 施工准备3一、技术准备3二、材料准备4三、劳动力计划4四、围堰搭设4五、施工导流5六、降排水措施6七、原有建筑物拆除6第五章 施工现场平面布置7一、施工机械修配厂7二、综合加工厂7第六章 施工方案及技术措施9一、施工测量10二、土方开挖工程施工方案10三、土方回填施工方案14四、管身段土施工17五、倒虹吸进出口段施工26第七章 施工安全保证措施28一、安全生产目标28二、建立安全管理机构28三、安全保证体系29四、建立安全保证制度29五、加强安全教育和安全措施的设置29六、加强安全工作的物质保障30七、其他保障30第八章 扬尘控制措施30一、管理目标30二、建立组织31三、巡视检查制度31四、施工扬尘控制管理措施32五、专项措施33第九章 文明施工、环境保护措施36一、文明施工36二、环境保护措施37第十章 成品保护措施38一、建立健全成品保护制度38二、材料保护措施38三、具体措施39四、完工前的清理41第十一章 质量保证措施41一、建立质量管理体制（见组织机构图）41二、施工质量保证措施43三、质量检查程44四、质量保证体系框图45第十二章冬雨季施工措施45一、冬期施工45二、雨季施工464.1 application of the Chinese language application for proxy bidding agency application system. 4.2 bidding agent applications should be submitted by the Agency included in the 5th chapter of the content, and than select file asked to provide appropriate documentation. 4.3 proxy application shall affix its official seal coding and page by page in the specified location.
