Painting, model culture creates new Ma Church community, creating Lake scenic spot culture education base, received high evaluation from provincial and municipal discipline Inspection Commission, the peoples daily special report. Constantly promote independent Commission against corruption culture construction to rural extends, created established Dahlin rural industry Park independent Commission against corruption culture positions, formed has a support service low double excellent of members lead team, constantly perfect and established Park funds assets management, and village audit supervision, and villagers democratic financial, system, strengthening Park party, and Chief, and financial, full public, powerful to guarantees has new rural construction, by city rural style clean government inspection unit led of height evaluation. Through the implementation of honest and clean government cultural construction, and effectively educate the broad masses of party members and cadres and consciously regulated behavior and discipline, honesty in politics and culture to create a good atmosphere and fresh development environment. Although we in implement implementation independent Commission against corruption guidelines aspects made has must effectiveness, but away from superior of requirements also exists must of distance, main performance for: a is system enough sound, education, and supervision, and prevention, and punishment, aspects long-term mechanism also enough perfect, especially in enrollment bid work regulatory aspects also needed strengthening; II is regulatory supervision exists lost of Yu wide, and lost of Yu soft, investigation illegal disciplinary case of efforts also needed strengthening, individual sector and cadres also different degree exists treat gift, not to benefits not do, and mess do of phenomenon; Three for honest work is the new situations and new problems in finding timely enough, treatment measures are not strong enough. To solve these problems, we will proceed from the following five aspects of rectification, make sure to implement the provisions of the code. (A) deepening the learning, enhance the consciousness of honesty in politics. To create event as an opportunity to Excel and learning party, further increasing the governance capability and advanced construction, reinforced rules of the broad masses of party members and cadres awareness, sense of responsibility, sense of honor, improve working ability and level of scientific development. Should make full use of meetings, in particular central group learning opportunity, further strengthening the study and education of the code, the intensive warning education, education the majority of party members and cadres known fear, knew fear, honesty in politics of tension the strings, consciousness and enhancing the implementation of the initiative. Also, pay attention to apply what they have learned, consciously study results into planning work, new ideas,G206东流至尧渡段建设工程NO2-1合同段石方路基试验段施工方案 编制： 审核： 批准： 安徽省公路桥梁工程有限公司G206东流至尧渡段建设工程NO2-1合同段项目部二零一四年十月十七日 目 录一、工程概况1二、试验段桩号及情况1三、试验段目的1四、试验依据1五、试验段施工计划2六、施工组织2 1、施工准备2 2、施工现场人员组织2 3、机械设备拟定3 4、 试验检测设备拟定3 5、 测量仪器配置拟定3七、主要施工工艺及方法3 1、 主要施工工艺流程图4 2、 施工方法4 2.1、测量放样4 2.2、清表整平4 2.3、分层摊铺5 2.4、碾压5 2.5、检测6 2.6、验收7 2.7、试验段总结报告形成及上报7 2.8、路基回填碾压方法示意7八、试验段施工质量保证措施8九、试验段施工安全保证措施8十、试验段施工的环保措施10new measures to promote work, the courage to take responsibility, dare to break hard to ensure district, Government decisions and arrangements to implement. (B) strengthening supervision, severely punish acts of violation. One is to open the channels of supervision. Vigorously promote the party affairs public, open, widely accepted supervision by the masses, pay attention to social groups and public opinion supervision, the powerful force formed to urge party members and leading cadres properly exercise their powers. Second, strong supervision and inspection. Democratic life into full play, important briefings, reports related to personal matters and evaluation of cadres study of inner-party supervisory system, a comprehensive grasp of guidelines for the implementation of the independent Commission against corruption-related cases of leading cadres of party members, focus on strengthening key areas of project selection, funding, officials monitor, detect and rectify the problem, promote honesty in politics. Third, strengthen disciplinary investigation. Seriously the implementation of JI .Recently, the County leading bodies at the county level to carry out three trees practice, which is to improve the governing ability and promoting the development of XX effective measure. I carefully follow your deployment requirements, and actively participate in the three trees campaign. Read Group, prepared by the Department in the near future of the ideological and political construction of leading cadres in the city reader, read the relevant information, larger harvest, inspired. I think the ability of repelling is to strengthen the partys governing capacity in questions of the construction of meaning, an important topic remains in front of party members and cadres at all levels, we need to further explore and ponder. The ability of repelling the name suggests, is asking party members and cadres at all levels in particular, leading cadres at all levels, not only ourselves, establish a correct concept of the independent Commission against corruption, political integrity, self-discipline, rejection of corruption, made for the people, pragmatic, honest leadership, and strengthen the sense of responsibility, earnestly implement the responsibility of uncorrupted, implementation of the baolian anti-corruption measures to ensure the realization of business-building, construction of a win-win situation. Next, I combined with their thinking, experience and contact XX practical, on how to enhance the ability of repelling, on four aspects of cognition. Irregularities, please comment. First, the construction of the propulsion system, and enhance the system of corruption since the founding of our party, have been thinking about tackling corruption. Currently, democratic legal system, management system and supervision mechanism is not perfect, administrative acts are not very standardized, Enterprise behavior and market behavior, corruption presents a diverse, pluralistic, complex trends, this shift the struggle between the two, will accompany安徽省公路桥梁工程有限公司 石方路基试验段施工方案一、工程概况G206东流至尧渡段（N02-1）改建工程项目起讫桩号为：K0+000K9+900，设计里程全长9.9Km。自东至县东流镇狭阳村，经张岗村、小黄泥湖、泉水湖至终点沿线拟新建桥梁3座，包括：管山桥、小黄泥湖桥、泉水湖桥。该项目公路等级一级公路，计算设计行车速度为80Km/小时，设计为双向6车道，路面宽34m，路基宽36.07m。本标段主要工程量：路基挖方约81万m3，填方约114万m3，借石方约46.5万m3。二、试验段桩号及情况我部根据设计文件，结合整个路段的实际情况，经现场勘察、研究，选定K5+600K5+780段为试验段，长度180m。该段地处K6+680K7+100的2#取土场和挖方段，石方运距较近，原地表为水田及旱地，最大填土高度3.1米，基底平均宽度为41.56米，总填方数量为29000余立方米。三、试验段目的主要是为了保证整个段面施工顺利进行，确保石方路基的工程质量和取得指导全面施工有效的试验数据和施工工艺，为今后施工提供控制依据，具体如下：1、机械设备的类型及最佳组合；2、压实设备的碾压速度及遍数、沉降差等相关参数及质量控制标准；3、（施工）石方路堤的施工工艺；4、填料的松铺系数等各种技术参数。5、摸索并总结如何依据质量标准以及部分质量标准进行规范的程序管理方法和质量控制手段。四、试验依据1、安徽省G206公路东流至尧渡段建设工程两阶段施工图设计文件；2、公路土工试验规程JTGE40-2007;3、公路路基施工技术规范(JTG F10-2006);4、公路工程质量检验评定标准JTGF80/1-2004；5、机械设备状况、技术力量、施工能力、现场实际情况。五、试验段施工计划计划开工日期：2014年10月18日，计划完成日期2014年11月30日。六、施工组织1、施工准备 （1）根据设计文件给出的控制网点，恢复路线，并进行复测。 （2）修筑进场便道，以便机械及时进场和汽车弃土。 （3）填筑地段开挖排水沟，以降低地下水位。 （4）挖方段清表，表土运到弃土场。2、施工现场人员组织为了做好试验段工作，项目部成立了专门机构，将认真开展工作，为以后的工作打下基础。石方路基试验段由路基三队完成，项目总工胡延辉全面负责，路士军负责机械人员的调配、协调，路基工程师郝鑫负责试验段的技术工作，施工人员易瑞保证工程质量，测量人员徐少劼、刘亚洲负责测量放线、松铺系数、沉降量的检测工作，试验人员赵昌飞、艾景周负责孔隙率的检测工作，安全人员周建锋负责现场安全监督检查。工程部长：路士军路基工程师：郝鑫项目总工：胡延辉施工员易瑞试验 赵昌飞艾景周测量 徐少劼刘亚洲安全 周建锋技术 员 朱 非 非其人员组织机构见图：3、机械设备拟定序号机械名称规格型号数量状况1推土机SD-131良好2挖掘机WY1002良好3压路机YZ202良好4装载机ZL50 1良好5自卸汽车10良好6洒水车1良好4、 试验检测设备拟定序号仪器、设备与设施名称规格型号用途、功能规格数量1电热鼓风干燥箱CWJ-8土工试验12电 动 振 筛 机ZBSX-92A土工试验13液塑限联合测定仪FG-土工试验14电 动 击 实 仪LZ-ZD土工试验15灌砂法密度测定仪CRY-11土工试验16土 样 标 准 筛FB-1土工试验17电 子 秤30kg28承载比CBR测定仪1mm/min土工试验19酒 精土工试验若干5、 测量仪器配置拟定仪器名称型 号用途功能数量自动安平水准仪苏光DSZ2沉降观测2全 站 仪尼康DTM-452C中桩边桩放样1GPS中海达V60中桩边桩放样1七、主要施工工艺及方法 1、 主要施工工艺流程图测 量 放 样场 地 清 理基 底 处 理填 料 装 运分 层 填 筑摊 铺 平 整振 动 碾 压试 验 检 测 路 基 成 形路 基 整 修 验 收填 石 区 段平 整 区 段碾 压 区 段检 测 区 段合 格填 料 检 测填 料 准 备2、 施工方法2.1、测量放样根据图纸和监理工程师提供的测设基准资料进行恢复定线测量，对于永久性坐标点、中线控制桩、转点桩、交点桩、水准点等认真核对，并做好防护，将结果保留到交工验收。填筑前，根据主线逐桩坐标表，从控制点采用水准仪在试验段纵向每10米选定一个测量断面进行断面复测，测量每个断面填筑前原地面高程，每断面测点布置不少于8个，并对测点做详细记录，放出路基中桩，根据路基横断面图，算出左右两侧边桩位置后，在实地放出试验段边桩。2.2、清表整平根据现场实际情况，对试验路段地表进行清表工作，对地表树根、农作物根系和表土全部清除，清表深度可根据实际情况控制；清表完成经检验合格后，采用振动碾进行地基压实处理，对局部坑洼处采用合格回填料进行回填，并碾压平整密实，确保全范围路基压实后满足90%要求，并采用石灰铺撒白线控制回填边线。2.3、打方格网根据运输自卸车装载能力为18m3，按50cm的松铺厚度填筑，根据运输车的斗容计算每车的摊铺面积，在填筑面上用石灰打出66m的方格网，填筑前用石灰撒出路基边线，立出施工标尺，由专人指挥卸料。2.4、摊铺填石路堤应采用石质均匀、单轴饱和抗压强度均满足要求的石料填筑，填筑石料运输采用挖掘机配合自卸汽车进行，装料时尽量使填料混合均匀，避免大粒径过分集中，岩性较大差别的石块，应分层分段摊铺，严禁软石和硬石混合使用。石料摊铺按水平分层、先低后高，先两侧后中间卸料。填石路堤的堆料完成后，即可进行摊铺，根据岩性我部路基填筑层厚度按松铺50cm控制; 石块的最大粒径不得超过50cm，不超过层厚的2/3 。在初步进行摊铺完成后，对超粒径的石块要进行人工破碎或挑除，满足技术规范要求粒径不大于摊铺厚度的2/3控制。2.5、整平为保证平整度及高程能满足要求，在摊铺完成后，采用推土机将填料推平、整平，人工辅助挖掘机精平。填筑路堤时从原地面按全宽填筑，填料铺设的宽度超过每层路堤的设计宽度左右侧宽出50cm的超宽碾压，以保证边坡修整的净宽度及完工后的路堤边缘有足够的压实度。2.6、碾压填石路堤由于粒料之间没有粘聚力，主要是靠填料之间相互镶嵌、紧密咬合，达到足够大的摩阻力来抵抗路基变形，因此，填石路堤碾压施工需采用振动碾压设备，在施工中采用20t振动压路机进行碾压施工。施工中，碾压速度控制在2-4km/h，铺料结束后，先静压一遍后再进行振动碾压至6遍完成后，最后静压1遍收面。碾压顺序由两侧开始向中间碾压，之后由中间相两侧碾压，碾压每次要求错轮1/3轮宽。对于有明显空洞、孔隙的地方补充细料后再进行碾压，若仍有松动石块，用合适粒径的小石块嵌缝，并用手锤敲紧。在每层标准松铺厚度上碾压完成每一遍后，应根据现场情况10m一个断面或在现场监理指示下，初拟选定每断面不少于10个检测点进行现场检测试验。2.7、检测石方填料填筑试验段压实按试验层分别进行。试验段碾压方案为：将180m41.56m试验区分为60m41.56m、60m41.56m和60m41.56m三个区域，松铺厚度为50cm。均采用20t振动压路机进行碾压，按碾压812遍后所测压实度进行比较，碾压施工程序为先静压2遍，弱振2遍，强振48遍，再静压2遍；当强振第二遍后由项目部测量人员测出标高算出压实厚度，强振第三遍、第四遍直到孔隙率达到“表：填石路堤上、下路堤压实质量标准”、压实沉降差在3mm的要求后为止，在对其碾压数据进行分析，总结出达到设计的标准要求时该层石方填料松铺厚度为50cm的最佳碾压工艺及参数。总结三个区域最佳松铺厚度和最佳碾压机具组合及最佳碾压遍数，继续施工直至施工完下路堤、上路堤、下路床及上路床即达到路基顶面设计标高，记录好检测结果和施工工艺。检测点应均匀分布碾压面，采用水准仪测量各遍碾压后对应检测点的高程及碾压后测点的孔隙率，在孔隙率满足技术要求的前提下，选取具有代表性的检测部位，采用大坑（最大粒径的1.5-2.0倍）和水袋法进行；采用软质石料（15-30Mpa）填石路堤压实质量控制标准：压实标准的确定根据规范要求，填石路堤的压实标准可采用孔隙率及压实沉降差进行确定。孔隙率检测应满足“表：填石路堤上、下路堤压实质量标准”要求。 表：填石路堤上、下路堤压实质量标准分区路面底面以下深度（m）硬质石料孔隙率（%）中硬石料孔隙率（%）软质石料孔隙率（%）上路堤0.81.50232220下路堤l.50252422、压实沉降差检测方法：首先在压实后的路堤上沿着路堤纵向布点，距离10米左右，横向间距17米或视现场情况而定。在布好的点位上，用白石灰或红油漆做出醒目的标记。用水准仪测量高程，为减少误差，准备10cm直径的钢球，放置在测点上。然后再用振动压路机进行碾压检测，碾压遍数为2遍，碾压后无明显轮迹。然后再用水准仪测定各点高程，各测点在碾压前后的高差，就是测点的压实沉降差，沉降差小于等于3mm时，可认为路基已被压实。2.8、验收碾压结束后质检工程师即带领试验人员和测量人员对路基碾压进行随机抽样检查，试验人员主要对检测点进行孔隙率检测，测量人员要对路基监测点碾压后沉降高层、平整度等项目进行检测，若有不合格的部分立即进行补压或采用其它有效措施，直到达到合格为止，经自检及监理抽检合格后方可进行下层的回填。2.9、试验段总结报告形成及上报施工结束后，在驻地监理工程师的认可下，将测量资料，相关试验资料及施工段填筑时机械配备的大小、数量、类型按实际情况进行统计和整理、并加以总结，得出不同机械压实石方填料适宜的松铺厚度和相应的碾压遍数、最佳的机械配备和合理的施工组织。数据的收集主要通过试验室对施工现场所取的试样进行试验所得，并通过微机对之进行系统处理、分类，并将之上报有关单位，最后归档。拿出实施性指导方案上报驻地监理及业主，指导K0+000K9+900范围内路基土石方填筑施工。 其试验段技术质量成果主要内容有：（1）测量技术参数汇总，（2）压实遍数、孔隙率与沉降差关系曲线图，（3）现场测量、试验记录，（4）现场施工影像资料等。2.10、路基填筑碾压方法示意 八、试验段施工质量保证体系为确保工程质量，做好试验段的各项试验质检工作，我部制定了以下措施：成立现场质检小组对整个工程进行全方位的质量跟踪检测和试验工作。对违反施工程序、施工工艺的现象及时更正、处理、督促施工人员严格按规范和技术要求施工，加强施工过程中的质量管理。1、施工严格按交通部颁布现行的公路工程技术标准及有关设计和施工规范、施工图纸进行操作，工程质量按交通部颁布现行的公路工程质量检验评定标准执行。2、严格按规程规范和设计技术要求或监理工程师指令施工，控制施工过程。3、对于影响工程质量的关键项目实行重点检验，全过程控制。路基施工主要的关键项目有：取料取样试验、填料松铺厚度、碾压遍数、路基压实孔隙率检测、排水措施、石方爆破设计和现场施工控制。九、试验段施工安全保证
