11、cadres in enterprise development in the广西科伦制药有限公司苏桥分公司生产基地建设载体桩基工程 施工方案施工单位(章):十一冶建设集团有限责任公司编 制:审 核:审 批:日 期:2012年 10月 22日 监理单位(章):桂林华厦建设监理有限责任公司审批意见:钻孔灌注桩施工方案一、 工程概况本工程钻孔灌注桩基础桩径设计为1.0m,共计78根,最大桩长35m,最小桩长18m,平均23m。经工程地质勘探、调查和查阅区域地质资料,本标段沿线表层为58米低液限粘土,呈软塑硬塑状态,以下到泥岩层的低液限粘土呈硬塑坚硬状态,局部为24米的中粗砂,中密。沿线地下水以第四
12、系孔隙型潜水及上层滞水为主,水量不大,水位受季节影响较大,雨季地下水位上升,约37米,枯水期地下水位下降,约510米。二、 施工总体布置1、 项目管理机构拟投入本工程主要项目管理人员20人,其机构及职能设置见附表6.1。2、 施工区域划分及顺序本标段桩基主要集中在长春北互通内,施工场地受到长春绕城高速及铁路的限制,施工场地相对狭窄。故对本互通内桩基进行合理的区域划分及施工顺序的安排,有利于加快施工进度。根据图纸及现场实际情况,本标段桩基以绕城高速为界划分为两个区域。具体施工顺序见进度计划。3、 施工方法根据本工程的地质情况,成孔采用泥浆护壁,钻机钻进成孔;清孔方式采用反循环清孔;钢筋笼现场分节
13、制作,吊车辅助安放,孔口焊接;混凝土采用搅拌站集中拌和,用混凝土搅拌运输车运输到孔口,导管法灌注。4、 施工力量安排本工程工期紧,桩基数量大,质量要求高,因此除必须配备施工经验丰富、组织能力强的项目班子,施工力量的投入是根本保证。根据本工程的规模和施工进度的安排,我们拟在施工期间投入139人,其中管理人员20人。详见附表6.2“劳动力配置计划表”。拟投入GPS-2000型钻机12台,砼搅拌运输车3台,16T汽车吊2台,挖掘机1台,泥浆运输车1台,电焊机6台,钢筋弯曲机、切割机各1台,其他小型机械若干。详见6.3“主要机械设备配置计划”。三、 施工平面布置1、 临时道路本互通内便道设置在主线左侧
14、坡脚处,便道宽6m,采用30cm厚山坡土,20cm碎石填筑。与乡镇道路相接。 便道两侧设置排水沟。2、 钢筋加工场地本工程钢筋笼采取现场分段制作,吊车辅助安放,孔口焊接。各类钢材及钢筋笼按不同规格堆放整齐、设置标识牌和检验状态,钢筋堆放采用下垫上盖,防止钢筋锈蚀。3、 施工用水由于本标段桩基工程采用回旋钻成孔施工方法,用水量大。前期按每天成桩2根(桩径1.5m),桩长23m,每方土变换成泥浆需要3m3水计,每天需用水300 m3。现场采取打机井,泵量15 m3/h,设2口机井。工作进入正常,钻机加至12台,每天需水量达到900 m3。按桩位及用水量就近打机井,计划设置6口机井。4、 施工用电主
