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 industry's 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 China's 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 city's 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 .*排涝泵站 施工工法目 录1编制依据 12质量控制要点 1一、分部工程主要施工内容概述 2二、控制工程质量、进度时间、降低成本的建议 4三、工程的施工工艺、方法 5（1）大面积平整场地、机械挖土施工工法 5（2）基坑和管沟回填土施工工法 9（3）水泥搅拌桩施工工法 13（4）钢筋绑扎与安装工程施工工法 18（5）钢筋及埋件手工电弧焊施工工法 22（6）现浇混凝土框架（包括框架剪力墙）结构模板施工工法 28（7）现浇混凝土施工工法 43（8）砖砌体砌筑施工工法 48（9）室内外抹水泥砂浆施工工法 54（10）室内外墙面贴陶瓷锦砖施工工法 60（11）外墙饰面贴面砖工程施工工法 65（12）地砖铺贴施工工法 70（13）瓷砖踢脚线铺贴施工工法 73（14）扶手、栏杆安装施工工法 73（15）乳胶漆施工工法 74（16）电气安装工程施工工法 75四、材料用量计划 91五、主要施工机具进场计划 91六、主要材料的技术标准、参数、供货能力、质量保证措施和出厂合格证主要材料的控制 92七、委外加工半成品控制 94八、质检管理 94九、确保工程质量的技术组织措施 95十、质量检查程序表图 97十一、质量保证措施 9712、 工程质量体系图 101十三、确保安全生产的技术组织措施 102十四、安全文明管理体系 104十五、施工安全防护措施 104十六、防火安全措施 104十七、施工现场临时用电安全措施 106十八、机械设备安全管理措施 107十九、确保文明施工的技术组织措施 107二十、确保工期的技术组织措施 109二十一、降低工程造价、工期措施 111二十二、成品保护措施 111二十三、施工队伍的各项组织机构构成、配属情况和管理制度、 管理体系及质量保证措施体系 112二十四、施工测量 116二十五箱涵施工过程中的控制 117箱涵及出口闸分部工程施工工法1编制依据：钢筋砼施工及验收规范（GB50204-2002）给水排水构筑物施工及验收规范（GBJ141-90）建筑地基基础工程施工质量验收规范（GBJ50202-2002）2质量控制要点：（1）箱涵支护桩的放线定位；（2）原材料进场报验及现场见证取样送检；（3）基坑开挖、排水；（4）钢筋、壁板模板制作与安装；（5）砼浇筑；（6）箱涵回填与压实；（7）工程进度计划与节点控制；（8）安全、文明施工措施。3达到的目标值：（1）报验及时，程序规范，资料真实、标准、齐全；（2）部位工程合格率达到100%；（3）工程质量达到建设工程质量验收统一标准（GB50300-2001）。1、 分部工程主要施工内容概述： 1、箱涵及出口闸分部工程基础地基根据地质勘探资料，为淤泥层、细纱淤泥层，设计地基处理方法：采用水泥搅拌桩进行地基水泥土搅拌固结，增加地基持力以满足建筑物的荷载。2、箱涵及出口闸分部工程划分一共有24个单元工程。3、箱涵及出口闸分部工程包含单元工程有如下：箱涵及出口闸段基础开挖工程；箱涵及出口闸段水泥搅拌桩工程；箱涵及出口闸段垫层工程；箱涵及出口闸段底板砼工程；箱涵及出口闸段墙身、顶板砼工程；箱涵段进入孔壁砼工程；箱涵段进入孔盖板砼；箱涵段进入孔盖板安装；出口闸检修便桥顶板；出口闸段二期砼；启闭机房9.60高程柱子；启闭机房9.60高程梁板砼工程；启闭机房13.10高程柱子；启闭机房屋面层梁板砼工程；人行桥柱和托梁砼工程；人行桥浆砌石基础；人行桥梁板砼工程；启闭机房砌砖；启闭机房门窗安装；启闭机房室内抹灰；（21）启闭机房楼地面；（22）启闭机房外墙抹灰；（23）启闭机房外墙饰面砖；（24）启闭机房排水安装工程；（25）左侧4.40，右侧4.40高程以下土方回填。4、施工工序包含：基础土方开挖；地基水泥搅拌桩施工；钢筋混凝土底板、箱涵墙体、顶板；框架柱、梁、结构板；人行钢筋混凝土桥；预制钢筋盖板；二期砼施工；室内土方回填；钢筋混凝土结构钢筋制安；钢筋混凝土结构模板支立；启闭机房填充墙体；启闭机房室内墙体抹灰；启闭机房门窗安装；启闭机房室外墙体抹灰、饰面砖；启闭机房楼地面；启闭机房排水安装。5、把上述分部分项工程单元主要施工工法介绍如下：二、控制工程质量、进度时间、降低成本的建议： 1、建议本工程的设计工程师到场，以确保现场出现的设计图纸疑难问题的及时解决、施工技术性问题时能够按照业主的合理要求，以最合理的方案，最快的速度、最有效的措施进行协调解决，保证施工顺利进行，从而提高效率，降低成本。2、建议业主召开施工前的进度计划会议。工程不能按业主要求如期交付使用是当前工程施工中存在的比较普遍的问题，虽然因素诸多，但施工组织管理不力是主要原因。因此应细化各施工队的进度计划，制定一个合理的符合实际的总进度表并认真监督执行，以确保各施工队以最低的消耗、最快的效率、最短的工期完成本工程。3、建议业主进行开工前的施工图纸技术会审，尽量做到施工时无变更，过程中少签证，减少施工过程中不必要的浪费，使本工程既能保证按期完工，又能较好地体现出原装饰设计方案的效果，这就需要各施工方对图纸的研究、理解细之又细，严之又严。以避免施工中出现疏漏给业主造成不必要的浪费。4、建议业主成立现场施工领导小组，由业主负责、监理挂帅、各参建单位参加。（1） 每周一例会，汇总当周进度、存在问题的解决协调办法、安排下周的工作，可采取现场讲评、磋商。（2） 成立技术领导小组，由监理和总包方技术负责人挂帅，经常性就工地各类技术问题进行会审，解决当天问题，以确保工程顺利进行。（3） 成立安全文明检查小组，由各施工队出人轮流值班检查工地安全文明施工情况，要求当值人员做好值班记录，以备业主和监理可随时检查。（4） 实行奖惩制度，对不按进度施工的、不安全文明施工的施工队（班组）要进行罚款。罚金用于奖励表现好的施工队（班组）。 （5） 监督举报制度，所有人员都可对不安全不文明现象进行举报，一经查实罚款50%奖励举报人。这是强化工地质量、安全文明管理的有效方法。 三、工程的施工工艺、方法（1）大面积平整场地、机械挖土施工工法 1、主要机具： 1.1、挖土机械有：挖土机、推土机、铲运机、自卸汽车等。 1.2、 一般机具有：铁锹（尖、平头两种）、手推车、小白线或20号铅丝和钢卷尺以及坡度尺等。 2、作业条件： 2.1、 土方开挖前，应根据施工方案的要求，将施工区域内的地下、地上障碍物清除和处理完毕。 2.2、 建筑物或构筑物的位置或场地的定位控制线（桩）、标准水平桩及开槽的灰线尺寸，必须经过检验合格；并办完预检手续。 2.3、 夜间施工时，应有足够的照明设施；在危险地段应设置明显标志，并要合理安排开挖顺序，防止错挖或超挖。 2.4、 开挖有地下水位的基坑槽、管沟时，应根据当地工程地质资料，采取措施降低地下水位。一般要降至开挖面以下0.5m，然后才能开挖。 2.5、 施工机械进入现场所经过的道路、桥梁和卸车设施等，应事先经过检查，必要时要进行加固或加宽等准备工作。 2.6、 选择土方机械，应根据施工区域的地形与作业条件、土的类别与厚度、总工程量和工期综合考虑，以能发挥施工机械的效率来确定，编好施工方案。 2.7、 施工区域运行路线的布置，应根据作业区域工程的大小、机械性能、运距和地形起伏等情况加以确定。 2.8、 在机械施工无法作业的部位和修整边坡坡度、清理槽底等，均应配备人工进行。 2.9、 熟悉图纸，做好技术交底。 3、工艺流程： 确定开挖的顺序和坡度 分段一次性开挖到底 修边和清底 1、坡度的确定： 1.1、 在天然湿度的土中，开挖基础坑（槽）、管沟时，当挖土深度不超过下列数值规定时，可不放坡，不加支撑。 1.2 、密实、中密的砂土和碎石类土（充填物为砂土）一1.0rn。 1.3、硬塑、可塑的粘质粉土及粉质粘土一1.25m。 1.4、 硬塑、可塑的粘土和碎石类土（充填物为粘性土）?.5m。 1.5、 坚硬性粘土一2.0m。 2、超过上述规定深度，在5m以内时，当土具有天然湿度、构造均匀、水文地质条件好，且无地下水，不加支撑的基坑（槽）和管沟，必须放坡。边坡最陡坡度应符合表l-3的规定。 各类土的边坡坡度 表1-3边 坡 坡 度 (高宽) 序号名称坡顶无荷载坡顶有静载坡顶有动载1中密的砂土11.0011.2511.50 2中密的碎石类土 (充填物为砂土)10.7511.0011.25 3硬塑的轻亚粘土10.6710.7511.00 4中密的碎石类土 (充填物为粘性土)10.5010.6710.75 5硬塑的亚粘土、粘土10.3310.5010.67 6老黄土10.1010.2510.33 7软土 (经井点降水后)11.00 注：当有成熟经验时，可不受本表限制。 3、使用时间较长的临时性挖方边坡坡度，应根据工程地质和边坡高度，结合当地同类土体的稳定坡度值确定。如地质条件好，土（岩）质较均匀，高度在10m以内的临时性挖方边坡坡度应按表1-4确定： 各类土的挖方边坡坡度 表1-4项次土 的 类 别边坡坡度 (高宽) 1砂土 (不包括细砂、粉砂)11.2511.15 2坚 硬10.7511.00 3硬 塑11.011.25 4充填坚硬、硬塑性粘土10.511.00 5充填砂土11.0011.50 注：当有成熟经验时，可不受本表限制。 4、 挖方经过不同类别土（岩）层或深度超过10m时，其边坡可做成折线形或台阶形。 5、城市挖方因邻近建筑物限制，而采用护坡桩时，可以不放坡，但要有护坡桩的施工方案。 6、开挖基坑（槽）或管沟时，应合理确定开挖顺序、路线及开挖深度。 7、采用推土机开挖大型基坑（槽）时，一般应从两端或顶端开始（纵向）推土，把土推向中部或顶端，暂时堆积，然后再横向将土推离基坑（槽）的两侧。 8、采用铲运机开挖大型基坑（槽）时，应纵向分行、分层按照坡度线向下铲挖，但每层的中心线地段应比两边稍高一些，以防积水。 10、采用反铲、拉铲挖土机开挖基坑（槽）或管沟时，其施工方法有两种； 11、端头挖土法：挖土机从基坑（槽）或管沟的端头以倒退行驶的方法进行开挖。自卸汽车配置在挖土机的两侧装运土。 12、侧向挖土法：挖土机一面沿着基坑（槽）或管沟的一侧移动，自卸汽车在另一侧装运土。 13、挖土机沿挖方边缘移动时，机械距离边坡上缘的宽度不得小于基坑（槽）或管沟深度的1/2。如挖土深度超过5m时，应按专业性施工方案来确定。 14、土方开挖宜从上到下分层分段依次进行。
