土方工程试验段(素土)施工总结

BN-05标K28+635～K28+870土方工程试验段已施工成型，经道路、测量、试验等各专业工程师验收合格，各项技术指标均符合JIJ071-98<<公路工程质量检验评定标准>>及招标文件技术规范要求，现总结试验段施工成果上报，拟在此基础上进行本标段大规模土方工程施工。
一、 施工方法
<一>、原材料
选用本标段1#取土坑土源，标准密度为1.85g∕m3，K28+000～K29+000段原基标准密度为1.81 g∕m3，(击实资料附后)，经试验检测，1#取土坑土粒最大粒径小于50mm，其中10-15mm土块含量不超过5%，硫酸盐含量不超过0.8%，腐植土含量不超过10%，各项指标均符合规范要求，可用于路基填筑。
<二>、施工流程安排
各项标准试验成果       路基、取土坑清表    填前压实           土料开采、运输、填筑、压实         自检、监理工程师验收进入下道工序施工
<三>、主要施工工序和施工方法
1、原基验收
本标段试验段选在K28+635～K28+870段，施工前，先进行路基清表，按照图示的1#取土场，清除取土坑土
Earthworks test section (element earth) Construction Summary

BN-05 standard K28 +635 ~ K28 +870 earthwork construction test section has been formed, by road, measuring and test, inspection and acceptance by the professional engineer, the technical indicators are in line with JIJ071-98 <<Highway Engineering Quality Inspection and Evaluation Standards> > Technical specifications and tender documents, the results are summarized test section to report, to be conducted on the basis of this large-scale earthwork construction of the tenders.
1, construction method
"一", raw materials
Lot # 1 choice to take the pit of the soil source, standard density 1.85g/m3, K28 +000 ~ K29 +000 section primordia standard density 1.81 g/m3, (compaction data attached), by the test, a # get the maximum diameter of the pit Soil particles less than 50mm, 10-15mm clods of which not more than 5%, sulfate content of no more than 0.8%, humus content is not more than 10%, the indicators are in line with regulatory requirements, available in roadbed construction.
<2>, the construction process arrangements
The results of the standard test bed, clear the table to take the pit fill material compacted soil before the extraction, transport, filling, compaction self, supervising engineer construction acceptance into the next procedure
"三", the main construction process and construction methods
1, primordia acceptance
Lot chose the test section K28 +635 ~ K28 +870 section, the construction before clearing the table for subgrade, in accordance with the icons of a # fetching area, clear the check pit soil
