1、材料及检验
根据设计及规范要求,确定原材料的种类及品质，并将原材料送至
试验室进行化验和做水泥粉煤灰混凝土配合比试验。根据选定的配合比，经监理工程师同意后材料进场，根据现场实际情况,选用材料. 2、CFG桩桩位编号及施打顺序
根据设计图纸对桩位，按排列逐根编号，如Z1—1,Z1—2，Z1-3…，并在施工时,按布置图做好标识，以防因桩位过多而漏打或超打。 在选定CFG桩施工顺序时，主要应根据土性和桩距，充分考虑新打桩对已打桩的影响。施工顺序大体可分为两种类型，一是连续施打，如图1（1）所示,从1号桩开始，依次2号，3号…连续打下去；二是间隔跳打。可以隔根或隔行跳打，如图1（2）所示，先打1、3、5…，后打2、4、6…。

Good for this meeting, we requested the Standing Committee of the municipal party Committee, municipal Secretary General Tng Wenjin, the City Commission for discipline inspection Standing Committee Yng Xu, Jiang Jixue, Deputy Director of the personnel office, and other leading comrades present guidance allows us to warm applause for their welcome and thanks! Below, I first District Committee member of the 20XX team annual democratic meeting implementation of the corrective measures, as well as member of the team and of my own report guidelines for the implementation of the independent Commission against corruption statement invited leaders and comrades criticism. First, annual party on the 20XX team, Member of democratic life action plan implementation year 20XX, district democratic meeting a member of the team on \"study and practice the scientific Outlook on development\" theme, find a project supporting strong enough, the industry well enough, urban construction management level needs to be improved, livelihood improvement needs to be strengthened, district team itself, such as the five aspects. ear of 20XX, we find out the problems mentioned above, based on actual Shunqing construction and development, conscientiously sum up improvements, achieving significant development results and effectiveness of their work. (A) highlight the project handle, maintain high growth of investment. Adhere to the strategy as a Foundation, carrying out projects to promote increased stamina important. One is to increase the intensity of projects towards. Actively seek national and provincial policy support, superior special transfer payments, a variety of additional income will top 700 million Yuan, a number of key infrastructure projects, livelihood projects, industrial projects into the cage. Second, increasing the project attracts. This year a total of 23 signed a major project, of which 14 billion project, China Metallurgical group, vanke group, Guangdong hengda group, Taiwan Ruentex group, on the RI group, Shenzhen Kaisa, jifeng agricultural machinery, Mercedes-Benz, Audi 4S store and other large enterprises and projects have settled in Shunqing. Third, strengthen project construction. Annual implementation focus project 39 a, fixed assets investment total will breakthrough 12 billion yuan, created district yilai history high, South door dam, and five in shop old city transformation, and Ying China industrial concentrated district construction, and city main road construction, and Northeast steam Trade Center, and modern farmers industry Park, and vocational education city, and low rental, and also room construction, and features blocks build, and farmers market transformation, and \"rural version\" Street transformation, focus engineering speed up implementation, effectiveness obviously. Expected to be achieved this year, area-wide GDP 17 billion thrift of excellent traditional and style lack deep of understanding, one-sided think in now of good situation Xia, economic smooth more fast development, and reform made major progress, and people living significantly improve, and social the career made new progress, no necessary always hard has, no awareness to China also has many poverty area, and also has many poverty population of exists, more living improve has, more need keep hard of style. Three is not strictly honest. otal thought units is a water sector, clean self-discipline away from himself too far, no real processing good living of improve and hard, and thrift excellent traditional of relationship, no effective do comply with Constitution and party of regulations must from I do up, no right mercy good bitter Le, and wealth of relationship, no right awareness to in comply with Constitution and party of regulations aspects everyone has accountability. Four, future direction and improvement measures 1, belief and faith, strengthen party spirit.

2）CFG 桩施工完毕后，待桩体达到一定强度后（一般为3～7d)，方可进行开挖。开挖时，宜采用人工开挖，如基坑较深、开挖面积较大，可采用小型机械和人工联合开挖，应有专人指挥，保证铲斗离桩边应有一定的安全距离，同时应避免扰动桩间土和对设计桩顶标高以下的桩体产生损害。
3）挖至设计标高后,应剔除多余的桩头,剔除桩头时应采取如下措施:
①．找出桩顶标高位置，在同一水平面按同一角度对称放置2 个或4 个钢钎，用大锤同时击打,将桩头截断。桩头截断后，再用钢纤、手锤等工具沿桩周向桩心逐渐剔除多余的桩头，直至设计桩顶标高，并在桩顶上找平。
②．不可用重锤或重物横向击打桩体。 ③．桩头剔至设计标高,桩顶表面应凿至平整。
④．桩头剔至设计标高以下时，必须采取补救措施。如断裂面距桩顶标高不深，可接桩至设计标高,同时保护好桩间土不受扰动。 4） 保护土层和桩头清除至设计标高后，应尽快进行褥垫层的施工，以防桩间土被扰动。

Before the meeting, the way we take surveys solicited a views, combed, related to team building增大断桩的可能性。施工时可采用从中心向外推进的方案或从一边向另一边推进的方案。另外，在施工时要时刻观察地表概况，如发生地表隆起应停止施工,寻找原因. 2)缩颈、断桩现象及预防措施
①。桩的施工顺序与拔管速度是产生缩颈与断桩的主要因素。 在饱和软土中成桩,桩机的振动力较小，这时若采用连打作业，新打桩对已成桩的作用主要表现为挤压,使已成桩被挤成不规则形，严重的会产生缩颈和断桩.在上部有较硬的土层或中间夹有硬土层的土中成桩。当采用隔桩跳打工艺时,若已打桩硬结强度不太高,在中间打新桩时,已打桩有时被振断裂。
②。在成桩时如果拔管速度太快,会导致混凝土自重压力对周围淤泥压力的抵抗力减少而造成缩颈或断桩；而拔管速度太慢，则会使得桩的端部桩体水泥含量较少，桩顶浮浆过多,而且混凝土产生离析，造成桩身强度不均匀。
由此可见，根据施工地质情况，选择合理的施打顺序及拔管速度是防止缩颈及断桩的有效方法。
