北京市恒拘油田化学剂有限公司宿舍楼土方工程方案.doc

土方工程方案
1.编制依据
（1施工图纸：基础平面布置图结-1。
（2《地基与基础工程施工质量验收规范》
《建筑工程施工质量验收统一标准》
2.操作工艺
1）土方
开挖工程：先放好坡顶线、坡底线，经复测及验收合格后开始开挖。
2）第一布先挖去槽中混凝土路面和下水管道，然后自西向东和自东向西程S型为两台挖土机开挖开挖时槽底留100MM厚土体由人工随挖土机清理至-1.9米处。
3）土方开挖完毕后，测量人员随即放出基地线和基槽钎探布置点位，开始进行基槽钎探施工。
4）钎探完成后进行基槽验收，合格后在基底上放好槽边线。
5）为防止雨水浸泡基槽底，沿基坑边30CM外预挖50CM宽的临时排水沟，且在转角处社临时技积水坑，坑内配置一台抽水泵，随时抽出坑内积水。
6）土方回填工程；填土前应将槽底或地平上的垃圾等杂务清理干净。回填土的含水量要控制在范围
Earthworks program
1. Preparation of the basis
(1 construction drawings: floor plans based on node -1.
(2 "foundation and basis for acceptance of construction quality"
"Building Construction Quality Check"
2. Operation Process
1) Earthwork
Excavation: First put away crest line, slope the bottom line, and the acceptance by the retest after excavation.
2) The first cloth first dredged tank concrete pavement and sewer, and then from west to east and from east to west, two-way S-type excavator for the excavation excavation bottom left 100MM thick soil dug by hand with earth to clear up to -1.9 meters.
3) The earth excavation is completed, the surveyors immediately release base line and the base tank filler point and probe arrangement to commence construction of foundation trench filler probe.
4) drill exploration based upon completion of acceptance slot, put away after passing trough the substrate edges.
5) The base bottom to prevent rainwater soaking along the pre-dug pit outside edge 30CM 50CM wide temporary drainage ditches, and temporary technology community in the corner water pit, the pit configuration a pump, keep water out of the pit.
6) The earth filling works; fill the former should be on the bottom or the horizon and garbage clean up chores. Backfill in the area to control the moisture content
