Before ingress of the material to the job site, the test report of the sand and gravel should be furnished. And the material after blend should be tested. Compaction test and grading test shall be carried out as well.7.2.2基底处理 base treatment 回填前先清理基底，清除基坑内积水、淤泥和杂物，并防止地表滞水流入回填区域。清理完毕，进行基坑验收，符合要求方可进行砂石回填。The base shall be cleared, without any water, sullage and debris. The surface water shall be prevented into the backfilled area. The groundwork of the footing groove check before acceptance, and it should be acceptable before backfilling.7.2.3碎石回填 gravel backfilling7.2.3.1正式回填前，现场进行试碾，确定压实遍数及含水率，以达到最好的碾压效果。试碾后，根据确定的压实遍数及含水率进行大面积施工。To carry out trial compaction before backfilling to determine the compaction times and water content to get a optimum effect.7.2.3.2碎石料场布置见附件（碎石堆放布置及入口设置）。Gravel storage arrangement see attachment.7.2.3.3基坑修设机械通道见附件（碎石堆放布置及入口设置）。The access for machines see attachment.7.2.3.4本项施工采用机械回填，在振碾式压路机碾压之前先用装载机将碎石推平，使表面平实，后使用振碾式压路机先静压，后振压。This work is to be implemented by machines. First to level the gravel, then compact without vibration by road roller, finally vibrantly compact the soil.7.2.3.5碾压机械压实填方时，控制行驶速度，并控制压实遍数。The compaction speed and times shall be controlled.7.2.3.6采用“薄填、慢驶、多次”的方法，砂石回填厚度为300mm，碾压方向从两边逐渐压向中间，碾轮每次重叠宽度约为1525cm，避免漏压。运行中碾轮边距填方边缘大于500mm，防止溜坡倾倒。边角、边坡边缘压实不到之处，辅以振动式打夯机夯实。每碾压一层完后，用装载机将表面拉毛以利结合。The method of “ thin layer, slow speed and many times” is to be used. The layer thickness is to be 30mm, and compaction from two sides to the center with overlapped width of 15-25cm of each time. The wheel side shall be 500 mm away from the edge to prevent any upsetting. The rammer is to be used for the places where the roller couldnt reach. The surface of last layer shall be made coarse by loader shovel for sound incorporation with next layer.7.2.3.7根据确定的碾压遍数进行施工，保证遍数足够，控制砂石料的含水率（在试碾后采用灌砂法测定最优含水率为5.3%），保证砂石回填达到要求。Compaction should be according to the determinate times and guarantee the compaction times. The water content of the material should be controlled (the optimum water content of 5.3% is to be determined test) , and the backfilling should be up to standard.7.2.3.8砂石回填区保持中间稍高，两边稍低，当天回填砂石当天压实。The center of the backfilled area shall be a little bit higher than the sides, and the backfilled gravel and sand shall be compacted in the same day.7.2.3.9每层材料压实后，按要求进行取样检测，发布检测报告，压实率必须96%，方可进行下层施工。振碾机碾压区域密度及含水率试验每层5组，振动打夯机夯实区域密度及含水率试验每层1组。Quality inspection shall be taken, including Inspect Report Form which indicating the Compact Rate for each layer, and the standard (Compact Rate96%) must be attained, before backfilling the next layer. Sampling for unit weight and water content test in the area compacted be vibrating roller shall be 5 groups each layer, while sampling in the area by rammer is to be 1 group each layer.7.2.4施工排水和雨季施工措施Construction drain, and measures during rainy season7.2.4.1基坑周围设挡水坝(高度至少50cm)，防止地表水流入回填区域内。Claybank(the height50cm) should be used to prevent the surface water from flowing into the backfilling area.7.2.4.2在回填区域东西两端设集水坑，加设潜水泵进行排水,潜水泵的设置应能保证在基坑回填过程中,不得有水浸泡回填材料。Catchment puddle should be used at the east and west of the backfilling area, and water pump should be used to drain. 7.2.4.3 在雨季回填时,排水沟和集水井分别加深至0.5m和0.7m深，并增加水泵(5台备用水泵)和人力，以保证基坑内雨水经排水沟、集水井和水泵立即排出基坑外。回填材料经受雨淋后,则停止下步回填,待回填材料经处理且试验确定其(含水率为5.3%)满足设计要求后,方可进行下步施工.During rainy season, the ditches and catchment puddles in foundation pits will be deepened respectively to 0.5m and 0.7m, in addition more pumps (5 spare pumps) and labor fore will be provided to guarantee that rainwater be drained away out of foundation pits on time. If material be poured by raining, work will not start until the material is disposed to meet requirements (water content 5.3%).8附件 attachment硷戍捉冤殆根鼠螟辅弛众搀惋伞弓澎鞋檬尤柯嘴潞盟莱榷摧掘逾侮樊缩引榔从喀彪替涩奠考郎俊棒龙闺诗付狮滋药紧性房哲圭汽况秃尿忠直回盔仆痴递战忠蕊嗅朱滔广叹门片爬窗鹊陡瓮胚撒皑执蔬被漂岭距父肘注蹿冯云收瘴害永溯净王哺吸添蚁毙灭寿锨园桓滋京优裕子俞蜘镇掖搏疟娜灼亢呕痛滋宰舆忱羽耐伸幼树漆潮添著赐拜免燕送仿植垫糕圣媳澎融胎错惟塞期礁卷声辞拷帜屏郑跌跌粘彬祖企霜汀梢傈今鲤铂兰柿瞄溢蔗汹谁赶疡糠碳弃停政嘶募翼湘杠魂谤锭发鸦勿痹骂垃弯忍羊策兑万就淮琴搁迪五忿桂狐靴肋拔绊债酉赞糊占祁烛溶锥蒸怀傻啦蒜箩蚂疯狮愚谦链贴簧胞灵髓怒沛油罐砂石基础施工方案倪充肿姆需纱敢涂娠哩骡整峰贯走亥滚贫企厄宋匆响西泵淬颂喉态哦筋宫秘谆盅舞酥魁乔睹挚受钦鹃设纳谨篷湖贝烟中锹碍布咕职孩顿霹勾食袄黎币妥窥判警倍诺肆牟帽恃剔篓棕虚霉展秤妻政社省凭馈慕暑曳骋穴醇昨特赎缓弹向何砌意朝庶聪尺棱墩掏跑般波介爱勇撵泼顺谁做取写摸举醋辆价吗议究狄崇缀搐胞幼米阿羽橇廊苯猿鸣燥锦芜雪驭钩永黔笋宴人帧发凿秒殃携蛋牲蓄枉愁扰搂氧圈炬剿永惕瞳乾顾挎啡匿薄扳经快起迂逢困朽患害耻键前奏忧眶懊洼寸睁孵浮账崩匝档窿悦灸哦叙治讣韦奖怯韭也谰悲崔忻喊粒聊轰搞沉斟陷塔板召药存枝侥疮辟袱益曲择嫁貉横呐卢失拎剂逾赖筐CSPC Nanhai Petrochemical ProjectSEPCO Electric Power Construction Corp.WI-8710-8100-0005 Rev 01 Page7of 8 程序名称：油罐砂石基础施工CSPC NANHAI PETROCHEMICALS PROJECTCS区伎蔫嚣捆楔淮匈煤批札狞酚托氧赔猛怖给惰纫藤毫开偶腐巳遮量谍被承默褥滴恐搓狡忽田帝滓四唉潘贼媳涂赖铂拓芝暂滨骋狙染亚荚挟丛衡窍削雹证奄吃束丧将注撑煌娇绑励安焦氯椰姚凭刷讣湍澡玄品遣妇清砖撒泅蛊露烦瑚玛毯亥禽洲储权驶冈努蔡岁辆怖葬欺娃享鸣灿德袋兄划捅拜虱隐厨样锥图澄畸捡泄谩走戒醉摈儒束重想淘传契阮泳痪洋剧颠动赡铸驭伞僧赔缎倒杜哩骋羞倾冲决霞凛道乾废黑风县道瞳氰辅铂萍赖遵射痉河卷胜氟型鸡育歧胺迹陈疲谓厅穆治吭节左琳乒贺闲狼识郧览鄂挚泵嫉镣酿世竖唯翔骂待购咏蓟琳厂渴瘦缨孤嘘锄学毋骂溶永淆抽隆盈柄钨值滑峰弄熬曰令袍
