yuan, an increase of 17.5%; local government general budget revenue of 500 million Yuan, . 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, 桥台承台钢筋施工方案一、 钢筋原材：进场的原材按不同的型号、钢种分类堆放，并做好标识牌，并标明检验状态，到场的钢筋必须进行检验并报驻地监理工程师抽检，抽检合格后方可使用。二、 钢筋加工：（一）钢筋矫直：1、盘条钢筋（12mm以下钢筋）矫直，可视现场实有设备而定，采用绞磨拉直，电动卷扬机。2、盘条钢筋（12mm以上钢筋）矫直，数量较少时，允许在木墩上锤击矫直，但应注意防止击伤钢筋；当数量较多时，应在工作平台上用手动矫直器或机械矫直器进行矫直。3、要求矫直后的钢筋应平直，无局部折曲。钢筋表面不应有削弱截面的伤痕。（二）钢筋的除锈：钢筋表面应洁净，当钢筋表面有油渍、油污、铁锈和用锤敲击能剥落的浮皮时，均应在钢筋成型前清除干净。钢筋除锈采用钢丝刷刷绣。（三）钢筋的配料：1、钢筋弯钩类型（1）级钢筋的末端需作180弯钩，其圆弧弯曲直径D不应小于钢筋直径d的2.5倍，平直长度不小于钢筋直径d的3倍。每个弯钩增加长度为6.25d。（2）、级钢筋末端作90或135弯折时，钢筋的弯曲直径D；级钢筋不小于钢筋直径d的4倍，级钢筋不小于直径d的5倍。平直部分长度按设计要求确定；设计无具体要求时为3d。每个弯钩增加长度：135时为4.85d，90时为4.2d。（3）弯起钢筋中间部位弯折处的弯曲直径D，不应小于钢筋直径d的5倍。2、钢筋的弯曲伸长量钢筋的弯曲伸长量与钢筋材质、直径、加工方式及弯曲角度有关，一般可按下列规定计算：弯曲30时，伸长0.35d；弯曲45时，伸长0.5d；弯曲60时，伸长0.85d；弯曲90时，伸长1d；弯曲135时，伸长1.25d；弯曲180时，伸长1.5d。3、配料长度：钢筋配料长度应以设计图纸为依据，配好料后应编制配料单作为钢筋加工的依据。（1）主筋：a、采用搭接（搭接焊或绑扎接头）时；配料长度=直段长度+斜段长度+弯钩增加长度+搭接长度-弯曲伸长值。b、不用搭接时：配料长度=直段长度+斜段长度+弯钩增加长度-弯曲伸长值。以上两式中直段长度从弯钩的切点及设计的钢筋端点算。4、钢筋画线：根据配料长度和钢筋设计形状在工作平台上进行画线。画线宜从钢筋中间开始开始向两端进行，根据设计各段尺寸（考虑弯曲伸长量）将各弯曲点位置用石笔画出。5、切断：用人工切断、手动切断机或电动钢筋切断机切断。6、弯曲成型：钢筋弯曲前，应依据配料长度和弯曲形状，在工作平台上或木板上按照1:1的比例尺放出大样图，作为钢筋弯曲成型的比量标准。第一根钢筋弯曲成型后，应在大样图上认真比量，符合要求后再成批生产。成型后的钢筋形状要正确，平面上没有凹曲现象，在弯曲点处不得有裂纹。弯制加工完成的钢筋应分类存放在工棚内的架垫上，避免堆在露天，引起锈蚀、污染和踩踏变形。（四）钢筋接头：1、采用的钢筋接头类型必须符合设计要求和施工规范的规定。2、焊工必须持有劳动部门或技术部门颁发的焊工考试合格证（或上岗证），并在规定的范围内进行焊接操作。1）闪光对焊：（1）正式施焊前取样检验，每个焊工均应在每个工作开始时，先按实际焊接条件试焊3个对焊接头试件，按规定作冷弯实验，合格后方可正式进行焊接。（2）成品取样检验。以每200个（不足200个小时的以200个计）同类型接头为一批中随即切取6个试件，3个作拉力试验，三个作冷弯试验，全部合格，则该批钢筋焊接接头合格，填发钢筋焊接试验报告。如拉力试件、冷弯试件重作试验，视复试结果，再判该批对焊接头是否合格。（3）现场采用的对焊机型号为UN1-100型，相应的技术参数为：额定容量100KVA、初级电压380V、初级电压4.57.6V、暂载率20%，钳口夹紧力3540KN，焊接生产率2030次/小时。2）弧焊接接头，当每次改变钢筋级别、直径焊条牌号或调换焊工时，每个焊工应预先用相同材料，焊接条件和参数，制作3个抗拉试件，当试验结果均大于该级别钢筋的抗拉强度必须持有钢筋焊接试验报告时，证明焊接质量符合要求，方可正式施焊。a）钢筋接头施工工艺要点闪光对接焊头：为了保证对焊质量，钢筋的焊接端应在垂直于钢筋的轴线方向切平，两焊接端面应彼此平行。焊渣必须清除。在构件任一有钢筋焊接接头的区段内，闪光对焊接头的钢筋面积，在受拉区不应超过钢筋总面积的50%。电弧焊接接头：焊缝长度、宽度、厚度、焊条的性质应符合施工规范的要求。（五）对钢筋接头布置的规定：钢筋接头应设置在钢筋承受应力较小处，并就分散错开布置。现场指导施工的专业技术人员就根据结构长度与实际到货钢筋长度，预先进行钢筋接头纸面布置，然后交会，操作人员遵照施工。配构件“同一截面”内（即35d且不小于500mm长度内）受力钢筋接头的截面积占受力钢筋总截面积德百分率，应符合下表规定。（六）钢筋绑扎与安装：1、钢筋的绑扎、安装：钢筋的数量、位置、尺寸应符合设计要求。接头长度区段内受力钢筋接头面积的最大百分率接头形式接头面积最大百分率（%）受拉区受压区主钢筋绑扎接头2550主钢筋焊接接头50不限制注：焊接接头长度区段内是指35d（d为钢筋直径）长度范围内，但不的小于500mm，绑扎接头长度区段是指1.3倍搭接长度；在同一根根钢筋上应尽量少设接头。1）钢筋的交叉点应用20#铁线扎牢，绑扎时应注意相邻绑扎点的铁丝扣式要成八字形，以免骨架形式，网片歪斜变形。2）钢筋末端的弯钩，位于底层的钢筋应朝上，位于上层的钢筋应朝下。3）箍筋处设计有特殊要求外，应于受力钢筋垂直；箍筋弯钩叠合处，应沿受力钢筋方向错开布置。4）钢筋绑扎应结实牢固，在运输、安装及灌注砼过程中，不得有变形、开焊或松脱现象，否则重新返工。5）在钢筋安装入模时，在钢筋与模板之间应垫好水泥砂浆垫块，保证砼保护层符合设计要求。水泥砂浆垫块（在安装前提前预制，内放20#铁线做悬挂）强度不应低于钢筋砼设计强度等级，垫块要互相错开，分散布置，不得横贯保护层断面，严格禁止用碎石块或木楔做垫块。2、钢筋绑扎、安装允许偏差：（见下页）钢筋绑扎、安装完成后，清除模内杂物，施工单位负责人、主管专业技术人员和质量检查员，应对钢筋数量、位置、绑扎质量、结构尺寸、接头布置、保护层厚度、垫块、支撑锚固长度、模板等逐一进行自检，据实与设计图对照检查，符合标准后，由主管技术人员填写钢筋成品检查记录，并备齐有关资料，如钢筋及焊条出厂证明书、钢筋试验报告、钢筋焊接试验报告、焊工操作证、标高测量资料等。通告质量检查工程师、监理工程师一同到现场检查验收。经监理工程师、检查工程师确认合格后签证，钢筋作业这道工序才算最后完成，方准进行砼施工作业。未经质量检查工程师、监理工程师共同检查签证的钢筋工程，一律不得进行下道工序的施工。加工钢筋的允许偏差项 目允许偏差受力钢筋顺长度方向加工后的全长10弯起钢筋各部分尺寸20箍筋、螺旋筋各部分尺寸5焊接网及焊接骨架的允许偏差项 目允许偏差（mm）网片的长、宽10网眼的尺寸10网眼的对角线差10骨架的宽及高5骨架的长10钢筋的间距0，-20钢筋位置允许偏差检 查 项 目允许偏差受力钢筋间距两排以上的排距5同排梁、板、拱肋10基础、锚碇、墩台、柱20灌 注 桩20箍筋、横向水平钢筋、螺旋筋间距0，-20钢筋骨架尺寸长10宽、高或直径5弯起钢筋位置（mm）20保护层厚度柱、梁、拱肋5基础、锚碇、墩台10板3三、质量保证措施：1、制定质量方针、目标：质量方针：争创行业一流，实现业主期望，奉献满意工程。质量目标：分项工程：一次检查合格率100%，优良率95%以上，确保创优良工程，建设一流精品工程。在本工程的建设中，要求全体施工人员牢固树立“质量第一“的意识。2、建立质量保证体系：建立健全的质量保证体系，成立质量管理领导小组，并明确各自的职责。为确保工程达到优质工程，力对工程的管理突出质量的事前控制，重点强调质量的过程控制，做好工程质量的事后控制。四、安全保证措施：1、所有作业人员、行政、参观、测量、监理人员、进入现场要戴好安全帽。2、在基坑内进行钢筋的绑扎作业时注意基坑顶的安全防护工作。3、现场的施工用电由专人负责。施工现场用电装备采用行业统一规定的标准电源箱，并经常对用电设备进行安全检查。五、文明施工及环保设施：施工中认真遵守国家现行的有关环境保护法律，支持“以防为主、防治结合、综合治理、化害为利”的原则，采用有利措施，防止污染和破坏自然环境。采用的原料均来源于草本植物，并不包含任何人工合成添加剂。以健康养生为理念，以天然植物为原料，更加符合现代人的生活诉求，已经成为消费者日常饮料的主要选择。new 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
