12、762万元。本工程的浆砌石坝为M10浆砌块石重力坝，坝顶高程321m（高程采用1985国家高程基准，下同），石坝上游坝坡为1:0.1，石坝下游坝坡为1:0.7，坝顶宽度为3.0m，坝轴线长度为33.91m，坝底高程307m，最大坝高14m。浆砌石坝的主要工程量有：1、土方开挖1575m3(估算值，因地貌变化，具体以实际施工测量为准)；2、浆砌石坝4026.99m3；3、浆砌块石面勾平缝575m2;4、各类预制件及栏杆等附属设施。1.2、编制依据1、施工合同及设计施工图2、设计交底及施工图会审纪要3、浆砌石坝施工技术规定SD120-844、砌体工程施工质量验收规范GB50203-20025、混凝
13、土结构工程施工质量验收规范GB50204-2002二、施工准备2.1 材料及机具1、水泥：普通硅酸盐32.5R水泥，运到现场时必须有出厂合格证和出厂质量验收单，方可验收入库，水泥运到工地后，必须通过国家质量检测机构检验，其品种强度，性能必须符合设计要求。2、砂浆：采用M10（砌筑）及1:2水泥砂浆（勾缝及抹面），机械拌和。砂浆有良好的和易性，保水性和水透水性，稠度一般为4-6cm；砂浆采用天然砂，砂料质地坚硬、清洁，级配良好，最大粒径不超过5mm，平均料径不小于0.25mm。砂的含泥量不超过5%。3、块石：砌体所用块石采用坚硬、密实，无风化无裂缝，无粘附物质，清洁的石料，其强度满足设计要求（M
14、U20）。5、主要机具：挖掘机、自卸车、砂浆拌合机、斗车另备有大铲、灰刀、扁子、线坠、小白线、卷尺、水平尺、皮数杆、小水桶、灰槽等。2.2 劳动力部署针对本工程特点，我们将认真组织施工，并充分发挥企业的管理力量和技术装备优势。我公司将安排具有丰富施工经验的工程师承担本工程项目经理，项目经理部拟投入一支30人左右的施工队伍，拟投入管理人员6人，技术工人约20人，并且在全公司范围内抽调骨干力量参加本工程的施工，加强工程现场施工管理，从各个方面保证工程建设顺利、高效、优质完成。三、施工工艺3.1 测量放线采用NTS-320南方全站仪对石坝的主要四大角轴线相关尺寸进行测量放线。根据测量放线结果设置定位
15、桩，采用外控轴线向设计轴线量取。 采用S3水准仪对开挖部位的原始地貌进行复测，并做好记录。用石灰洒出开挖线，进行基础开挖。3.2 土方开挖1、土方开挖采用挖掘机及自卸车配合进行,由边到中，自上而下，分层循序进行取土。当开挖到接近路基设计顶面时，根据土质情况注意预留碾压沉落高度，严防超挖。挖土过程中，基底工作面按设计保持一定的纵、横坡度。2施工注意事项（1）、根据土方工程开挖深度和工程量的大小，选择机械和人工挖土或机械挖土方案。（2）、开挖应保持一定的距离和坡度，以保持开挖边坡部位的稳定，如现场条件不满足要求，应采取边坡支撑加固措施。并在施工中进行沉降和位移观测。（3）、弃土应及时运出，如需要临时堆土，或留作回填土，堆土坡脚至坑边距离应按开挖深度、边坡坡度和土的类别确定（应考虑堆土附加侧压力）。（4）、土方开挖工程完成后要尽量减少暴露时间，及时进行下一道工序的施工。如不能立即进行下一道工序。要预留1530cm厚覆盖土层，待基础施工时再挖去。（5）、工作前应查明施工场地明、暗障碍物（如电线、地下电缆、管道、坑道等）地点及走向，保证机械安全作业。（6）、机械行驶时，禁止搭乘其他人员。（7）、机械行走前，必须确认机械前没有人或障碍物，发出信号（按喇叭）后方能移动机械。工作中司机离岗时，必须将机械可靠
