| Abstract: | According to the karst geological characteristics of the construction site of the Chong-Zun Expressway in Guizhou province,the pile foundation construction in such karst geological conditions should be performed in the following way: holes should be bored chiefly with machinery,supplementally manually,and sometimes drilled in collaboration with manual excavation.Such simple but effective technical measures as laying pipes in the hole to drain,sending workers into the hole to fill-lay rug stones,and the firs... |
