在1979年莫斯科举行的学术座谈会上,瑞典《Линден-Алимак》公司介绍了一种利用土-石灰桩和《Alidrain》排水带软粘土深层压密设备。 土-石灰桩使用特殊设备(图1)敷设,该设备由带钻杆2的钻探工具1和支架3所组成,它们安装在基础机械4上。生石灰装在贮藏器5中,贮藏器装在汽车拖车6上。贮藏器的体积为2.5米~3,能保证设备连续工作4个小时。在这个时间里,可以保证总钻孔深度达150米。利用装有气动卸料系
At the academic symposium held in Moscow in 1979, Sweden’s “Линден-Алимак” company introduced a deep compaction device using soil-lime piles and “Alidrain” drainage belt soft clay. Soil-lime piles are laid using special equipment (Fig. 1) consisting of a drilling tool 1 with a drill pipe 2 and a bracket 3, which are mounted on the foundation machine 4. The lime is contained in the receptacle 5 and the receptacle is mounted on the car trailer 6 . The volume of the reservoir is 2.5 meters to 3, which ensures that the equipment can work continuously for 4 hours. During this time, it is guaranteed that the total drilling depth will be 150 meters. Utilize pneumatic discharge system
