所谓强力夯实法,即由起吊装置将夯锤提起,高度一般达到10～30米,然后脱钩,靠夯锤自由落体的能量来完成夯实软土地基的一种施工方法。最近几年来,国内、外用强夯法处理软土地基的已有不少工程,这些工程中的强夯都是使用了自动脱钩装置。但还需要人工完成夯锤的吊挂工作,这样每台班都必需占用一个工人。在挂钩工作中,又得跳上夯锤作业,操作十分麻烦劳累。为简化操作,改善作业劳动强度,节省劳力,缩短挂钩时间。我单位将强夯挂钩装置进行改进,制成如图所示的自动脱钩和挂钩装置。
The so-called strong compaction method, that is lifted by the lifting device to pick up the hammer, the height generally reaches 10 to 30 meters, and then decoupled, relying on the energy of the free fall of the hammer to complete a construction method for compaction of soft ground. In recent years, there have been many projects for domestic and foreign use of the soft ground method to deal with soft soil foundations. In these projects, powerful demolition devices are used. However, it is also necessary to manually complete the hanging work of the hammer so that each class must occupy one worker. In the work of hooking, you have to jump on the gong hammer operation, the operation is very cumbersome. To simplify operations, improve labor intensity, save labor, and shorten the hook time. Our unit will strengthen the hook device for improvement and make the automatic release and hook device as shown in the picture.
