In order to ensure normal teaching order, protecting students healthy growth, ensuring that national (property) is not lost, to prevent or minimize the occurrence of safety accidents, follow the prevent, rescue each other, ensure safety and reduce losses principle, according to the local conditions, make the management system. 1, the principal is the responsibility of school safety, school security under the leadership of President security work leading group. The head teacher to the leadership team is responsible for, implementation of the accountability system. 2, school monthly student knowledge about safety education, education should be diversified in the form every safety education for students of classes per week should be targeted. To carry on emergency issues dealing with education in General, self-help and mutual rescue knowledge. Emergency calls (such as 110, 119, 122, 120, and so on) use common sense in education. 3, the establishment of major accident reporting system. School students report major accident within an hour of education; student run and disappearances to report; report of the accident to a written report in triplicate, a correctional centre, a police station, a township peoples Government shall not conceal the accident. 4 week, teachers are on duty system, establish and improve the leadership values; strengthen the education, management of teaching activities in schools to ensure normal teaching order; responsible for school safety leadership always maintained close contact and district police stations, canvassing support from the police station on school safety and help. 5, strengthening teachers moral education, establish a dedicated love, improving education quality, observe the students psychological changes at any time and take preventive measures, no corporal punishment and covert corporal punishment on students, student out of the classroom, schools may not be. 6, units or departments use student Street propaganda or participate in the celebrations, as well as participating in other social work, without approval of the Correctional Centre, school principals consent, without organization. Without the approval of relevant departments, may organize students to participate in fire fighting, disaster relief and so on. 7, schools should educate students to obey the school rules and regulations, on time, on time home to prevent accidents. 8, school to school inspections on a regular basis, found hidden in time, and in severe cases, it is hard to eliminate immediately closed, and reported to the local peoples Government, education, and rule of law section. 9, the school should always check the internal walls, retaining walls, ponds, railings, handrails, doors, Windows, staircases and a variety of sports, extracurricular activities, facilities such as fire safety, infrastructure security, unsafe facility to immediately repair and demolition to ensure that teachers and students work, learn, live venues and facilities are safe and reliable. Song Lin Xiang Liu Jia ping elementary school March 2016 song Lin Xiang Liu Jia ping primary school fire safety systems to enhance fire safety, protection of public property and the life and property safety of teachers and students, school fire safety into day-to-day management, is developing the following fire safety system. 1, strengthen fire safety education of the whole school. According to the requirements of the Fire Services Act, so that everyone has of keeping fire control safety, protecting fire control facilities, fire prevention, reports of fire自贡恒大名都二项目施工组织（总）设计（地下室车库二区塔吊基础施工方案）编制单位：四川省第三建筑工程公司重庆公司编制时间：2015年7月施工组织设计（施工方案）会签表工程名称自贡恒大名都施工组织设计（施工方案）名称自贡恒大名都地下室车库二III区塔吊基础施工方案建设单位自贡鑫茂置业有限公司工程类别高层监理单位重庆市建永工程监理有限公司工程规模30000 结构形式剪力墙结构层数及总高度3层/12米分公司总工程师签字： 单位（盖章） 年 月 日工程科签字： 年 月 日项目部项目经理签字： 年 月 日项目技术负责人签字： 年 月 日编制人签字： 年 月 日预算负责人签字： 年 月 日监理单位意见签 字： 单位（盖章） 年 月 日建管/建设单位意见签 字： 单位（盖章） 年 月 日自贡恒大名都地下室车库二III区塔吊基础施工方案1、 编制依据1、重庆自贡恒大名都车库二基础设计施工图；2、重庆自贡恒大名都车库基础施工图；3、自贡恒大名都岩土工程勘察报告；4、塔吊租赁商提供的QTZ63（5010）塔吊基础参数资料。二、工程概况自贡恒大名都工程位于四川省自贡市大安区凤凰乡马吃水立交桥以东。结构形式为框架结构、框剪结构，建筑结构安全等级为二级。本地区抗震设防烈度为7度,丙类设防，设计基本地震加速度值0.10g。建筑群基础土质差异较大，基础采用二种形式:桩基础和条桩。地下车库为三层，高度12m。地下室车库二III区施工在即，为了满足垂直运输的需要，项目部拟订在地下车库1112/OEOG轴位置设置QTZ63塔吊一台。3、 塔吊概况自贡恒大名都地下室车库二III区采用四川省隆昌机械制造有限公司生产的QTZ63塔吊，该塔吊独立式起升高度为35m，最大工作幅度为半径50m，最大起重量3吨,公称起重力矩630KN.m。4、 塔吊基础选择 根据厂家提供的使用说明书，塔吊基础混凝土强度等级为C35，垫层为C15，找平层为C20。QTZ63型塔吊基础底面为5000*5000的正方形。承台基础配筋详见塔吊底盘式基础图。塔吊基础的地基承载力200KN/。根据地勘报告显示，为了满足塔吊基础对地基承载力的要求，必须以该位置中风岩层作为基础持力层，由于土层较深，为确保安全生产，塔吊基础需在承台下设置4根桩基。根据场地布置需要，塔吊承台基础顶标高为333.6m，塔吊基础承台的中心坐标定为X=50453.088，Y=69537.955(平面布置详附图二)，承台基础为5m*5m*1.3m的正方形(配筋详见附图)，承台预埋16-MJ10地脚螺栓共20件(位置及尺寸详见附图)，承台与桩基础布置详见附图三，承台垫层每边出10cm，砼标号为C15。桩基采用机械旋挖机成孔，桩径800mm。该位置原始地貌为333.2m，根据地勘报告BK9钻探数据显示，机械旋挖桩底标高定为321.2m即满足塔吊承载力设计要求，桩有效桩长为12.4m，桩端嵌入中风化岩层2m，砼标号采用C35，砼浇筑采用水下砼浇注方式，桩基配筋详见桩基配筋大样详图（附图四），桩身实际钻孔长度以现场收方记录为准。施工时先使用机械旋挖机开挖桩基然后用挖机开挖承台土石方(每边工作面30cm)承台垫层砼浇筑前用人工捡底承台和垫层四周用钢管和覆膜复合模板(1830mm*915mm*14mm)加固(详附图一)。桩基钢筋笼使用20吨汽车吊吊装下笼,二级钢均采用同直径三级钢(HRB400)替换。附图二附图三附图四5、 塔吊基础计算书1、 塔吊基础参数塔吊自重(包括压重)F1=372.00kN,最大起重荷载F2=50.00kN,塔吊倾覆力矩M=630.00kN.m,塔吊起重高度H=35m,塔身宽度B=1.6m，承台混凝土强度:C35,钢筋级别:级,承台长度Lc或宽度Bc=5.00m，桩砼强度35，Ec=3*104N/mm，直径d=1.50m,承台高度h=1.30m，桩中心与承台中心重合Gk=5*5*1.3*25=812.50kNFk=372.00kN，Fh=50.0kN，Mz=630+50.00*1.10=685kNm 2、 桩顶作用效应计算（1） 轴心竖向力作用下Nk=(FkGk)/n=(372.00+812.50)/1=1184.50kN（2）水平力作用下Hik=Fh /n=50.00/1=50.00kN3、桩基竖向承载力验算（1）单桩竖向极限承载力标准值计算hr=3.00m,d=1.50m=1500mm,hr/d=3.00/1.50=2,查表得，r=1.41Ap=D2/4=3.14(1.50)2/4=1.77m2 Qsk=uqsiki =dqsiai=3.141.501166.5=5494.22kNQrk=rfrkAp=1.4179501.77=19840.82kNQuk=Qsk+Qrk=5494.22+19840.82=25335.04kNRa=1/KQuk=1/225335.04=12667.52kN（2） 桩基竖向承载力计算 轴心竖向力作用下 Nk=1184.50kNRa=12667.52kN,竖向承载力满足要求。4、 桩基水平承载力验算（1） 单桩水平承载力特征值计算 Rha=0.75mftWo/Vm（1.25+22g）1+NN/mftAnm=2；ft=1.43，g=0.32%，E=Es/Ec=2.00105/3.00104=6.67,N=0.5,Vm=0.926,Wo=d/32d+2（E-1）gdo=0.34mAn=d/41+（E-1）g=1.80，N=Fk1.2Gk=1562kN，=0.52 Rha=82.46kN，Hik=40.00kNRha，水平承载力满足要求。5.抗拔桩基承载力验算（1）抗拔极限承载力标准值计算Tuk=iqsialiui=3845.95kN Tgk=1/nu1iqsiali=3845.95kN（2）抗拔承载力计算Ggp=Ggp1Ggp2=551.3018.80/1+559.10(18.80-10)/1=2481kNGp=Gp1Gp2=551.3025559.1025=812.5+1251.25=2063.75kNNk=1184.50kNTgk/2+Ggp=847.8+2575=4403.98kNNk=1184.50kNTuk/2+Gp=847.8+641.35=3986.73kN满足抗拔桩基承载力验算。6、 抗倾覆验算bi=5/2=2.5m,倾覆力矩M倾=MFhh=630+501.3=695kN.m抗倾覆力矩M抗=（FkGk）bi(Tuk/2+Gp)bi=12928.06kN.mM抗/M倾=12928.06/682=18.96抗倾覆验算18.961.6，满足要求。编制本施工方案时，分析了本工程的工程特点，地质条件和设计要求，结合我公司其它工地施工经验及教训，本着创一流的质量Electricity lines, equipment inspections, found hidden in time for rectification, maintenance, and security. 9, do not use an open flame in the classroom, prohibit burning stove, lit candles, mosquito repellent, no smoking, and banning messy wiring.
