土方工程試驗段(素土)施工總結
BN-05標K28+635～K28+870土方工程試驗段已施工成型，經道路、測量、試驗等各專業工程師驗收合格，各項技術指標均符合JIJ071-98<<公路工程質量檢驗評定標準>>及招標文件技術規范要求，現總結試驗段施工成果上報，擬在此基礎上進行本標段大規模土方工程施工。
一、 施工方法
<一>、原材料
選用本標段1#取土坑土源，標準密度為1.85g∕m3，K28+000～K29+000段原基標準密度為1.81 g∕m3，(擊實資料附后)，經試驗檢測，1#取土坑土粒最大粒徑小于50mm，其中10-15mm土塊含量不超過5%，硫酸鹽含量不超過0.8%，腐植土含量不超過10%，各項指標均符合規范要求，可用于路基填筑。
<二>、施工流程安排
各項標準試驗成果 路基、取土坑清表 填前壓實 土料開采、運輸、填筑、壓實 自檢、監理工程師驗收進入下道工序施工
<三>、主要施工工序和施工方法
1、原基驗收
本標段試驗段選在K28+635～K28+870段，施工前，先進行路基清表，按照圖示的1#取土場，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
