本次浇筑预估50小时
项目部成员两班倒
2台天泵、1台地泵同时作业
商混车进出场达400余次
浇筑量达到5000方
最终用时42小时
比预估用时提前8小时完成浇筑！
项目概况
望云松间 (北区) 项目位于科技六路以南，高新路以东，占地面积20795㎡，是集商业、酒店、办公、公寓、会议中心为一体的大型城市综合体。本项目由3栋单体及地下车库组成，总建筑面积约18.83万㎡。其中1#2#塔楼建筑高度249.1m(地下3层、地上52层)；此次浇筑对象为T3酒店，建筑高度99.7m(地下3层，地上23层)。
筏板概况
本次浇筑的T3酒店筏板厚度最厚为6.4m。浇筑筏板所需混凝土总方量约5000㎡，混凝土强度为C45P10。

推动项目高质量发展
承担此次大体积筏板浇筑的技术负责的是望云松间（北区）项目经理助理詹正书。本次浇筑施工方案依托于2#塔楼方案编写的经验，及1#塔楼筏板浇筑全程参与产生。从T3酒店的土方开挖开始，詹正书全程独立完成酒店栋砖胎膜施工方案、防水施工方案、槽钢支撑方案、大体积混凝土施工方案的编写工作，确保方案可实施、可操作，有创新、有亮点，最终落地执行。
难点一：筏板结构复杂
T3酒店筏板最厚厚度达6.4米，超厚筏板的浇筑部署及振捣难度非常大，设置串筒用于混凝土浇筑，使得混凝土下落高度不超过2米；设置振捣通道，加快振捣频率。同时，T3酒店具有较多不同深度的承台，这需要在浇筑速率和顺序上有更加严谨的策划，通过建立BIM三维模型，计算各模块混凝土方量。
难点二：温度控制
筏板混凝土强度等级为C45P10，最大厚度达6.4米，内部水化放热很大，温度梯度控制成为本次施工重点内容。采用电子测温无线传输系统进行测温。同时在混凝土表面铺盖棉毡，洒水浸湿，达到养护目的。
难点三：场地狭小
项目场地自身场地狭小，随着项目整体施工的进行，1、2#楼浇筑完成之后，T3酒店浇筑可用于车辆周转的余地仅为现场的四分之一，所以必须通过前期策划，合理布置泵车位置，严密规划回车路线。
转换思维
组织管理看谋略
技术质量组：
合理安排每台泵车浇筑方向确保筏板整天按照分层浇筑实施；时刻关注泵车后商混搅拌车的数量，确保混凝土连续供应；当某处混凝土浇筑时间过长即将出现板结现象时及时补料；关注混凝土的坍落度及质量，不合格时做退料处理；监督工人振捣，确保混凝土的流淌且不漏振。
试块留置 (抗渗、标养及同条件试块)；坍落度实验；混凝土入模温度测量；所管泵车混凝土签票及混凝土方量统计。
生产组：
现场安全巡检 (重点为：下面层钢筋振捣人员、机械打击)；现场安全应急预案执行。
交通组：
检查原材料、配合比、坍落度，商混质量不合格不发料；时刻与项目保持联系根据现场情况发料；及时了解并反馈搅拌站发货量 (包括总量、行驶在路上车辆装载商混方量)。
进场车辆小票；出场车辆小票签字；每隔1小时反馈进场商混量。
下基坑坡道车辆疏导；车辆等候区车辆疏导。
后勤保障组：
所有管理人员在基坑下就餐问题，及时补充饮用水，夜间加班期间食物及饮水供给。

花杰潘4183如何控制地泵浇筑混凝土的用量, -
季泉幸13368117714 ______ 没有太明白你指的“控制地泵浇筑量”的意思,如果是搅拌站调度的话,最主要的是根据现场调度或施工负责人的情况反馈发灰,给出不同的供应量.浇筑不同的部位,如底板、楼板、墙体、地面等其他部位时,工人施工浇筑速度会不同,这时主要的依据就是工人的施工速度了,有时一个小时会浇筑不到10方混凝土,而浇筑顺利的底板时,大功率的地泵,一个小时的浇筑量可能达到40-50方.
