- "8.the Overturning of or a collision with any object by-"
- The site has no overburden and the bedrock is exposed gray sandstone of medium-thick bedded construction and medium-fine particle structure.
- The site has no overburden and the bedrock is exposed purplish red sandy mudstone of thin-medium embedded construction and sandstone and mudstone structure.
- To cover or surround with mulch.
- The seal rocks are developed widely and the neocene marine mudstone is the regional seal.
- Engineering geological drilling: for bedrock and deep& thick overburden xy-100drilling machine shall be used and standard penetration test shall be made on the soil layer.soil drilling and trenching shall be arranged for the shallow overburden along the water intaking pipeline so as to survey thickness and properties of quaternary system overburden along the pipeline.
- The quaternary system overburden at area covered by pipe axis is1.6~ 8.0m earth surface is alluvium and proluvium slope proluvium silty clay and clay of quaternary system and with a thickness of1.6~ 4.8m.
- Constructional terrace in luowen town of houhe river basin is slightly developed especially on the left bank where the project site is located there are great areas of grade I terrace distributed with flat surface5~ 15m higher than river level and5m~ 10m thick 1700m long and10~ 200m wide overburden.the terrace is of foundation bed with2~ 5m upper part mainly contains clay and silty clay and lower part mainly composed of cobble-gravel layers.
- For bedrock drilling ordinary hard alloy driller can be adopted for vertical core-drilling with the addition of clear water during rotation.for overburden dry drilling process can be adopted.
- The porosity of tropical soils and implications for geomorphological and pedogenetic processes and the movement of solutions within the weathering cover
- "No dumps for overburden low grade ore or debris may be started without the approval in writing of the superintendent of mines."
- The failure forms causes and methods to appraise petroleum pitch coatings are summarized in the present paper.
- The construction scheme is briefly introduced herein and furthermore the diversion structures the composite scheme consisting of open caisson group adopted to treat the overburden of the foundation for the stage2longitudinal concrete cofferdam and the diversion method of bottom outlet combined with the dam gap used for the stage2diversion are described as well.
- The dam for chahanwusu hydropower station is the first one among the concrete faced rock-fill dams under construction with the height of over100m and the toe slab being constructed on thick and deep cover in china.
- Mainly control lithological boundary of overburden and stratum boundary of inferior geological body and spring spot of underground water.
