实践证明用强夯法加固地基是一种既经济、又可靠的方法,已为越来越多的地基工程所采用。为解决强夯起重机械的起重能力,在吊车吊臂端安装一门架,既增加了吊车的起重能力,又避免了吊车过力损坏。一些单位在用此种装置进行强夯时,因缺乏对其内在规律的认识,盲目使用,致使吊车门架倾翻事故时有发生。使得某些欲采用强夯技术的施工单位谈虎变色。为使新技术推广开,结合我公司六年的强夯施工实践,介绍一下这一组合机具规律和使用特点,以供参考。一、未加门架的吊车在强夯时的情况:吊车吊夯锤的情形如图1。开始夯时,夯锤 Practice has shown that strengthening the foundation with the ramming method is an economical and reliable method that has been adopted by more and more foundation projects. In order to solve the lifting capacity of the heavy-lift cranes, installing a gantry at the end of the crane arm not only increases the lifting capacity of the crane, but also avoids excessive damage to the crane. When some units used such devices to intensify their performance, they were blindly used due to lack of knowledge of their internal laws, causing the accidents of tilting of the crane’s gantry. Makes some construction companies that want to use tough technology to talk about tiger discoloration. In order to promote the opening of new technologies, combined with the six-year strong construction practice of our company, we introduce the combination of the law and the use of features for reference. First, the crane without a gantry is in a situation where the crane is powerful: The situation of a crane crane hammer is shown in Figure 1. When you start, you hammer
