随着国家基本建设的发展,我公司相继承接了几项大型工业厂房的吊装任务,这些厂房的混凝土预制柱最重达46吨,几座厂房都建筑在旷野地区,土质为亚粘土,又多在雨季施工。这样就给吊装工作带来极为不利的影响。如果采用大吨位汽车吊进行吊装势必要对施工现场进行处理,换土夯实或碴石碾压或有长枕木铺垫等处理现场,吊装费用就会十分昂贵。
With the development of national capital construction, our company undertook the lifting tasks of several large-scale industrial plants in succession. The concrete prefabricated columns of these plants have the most weight of 46 tons. Several of the plants are built in the wilderness area, the soil is sub-clay, and more Construction in the rainy season. This will have a very adverse impact on lifting work. If the use of large tonnage truck crane hoisting is necessary to deal with the construction site, for soil compaction or ballast stone crushed or bedding with long sleepers and other treatment site, hoisting costs can be very expensive.
