当在流沙淤泥地区施工时,开挖难以成坑,在流沙淤泥地区不易成孔,往往是施工时塌了挖,挖了又塌,而且还伴有水流出,给施工带来很大困难,当挖较深的洞时还会有危险出现。目前挖洞方法有挡土板法、沉箱法、爆扩法,但各有难以解决的缺陷。流沙淤泥桩孔机它能将挡板法、沉箱法、电钻钻孔等优点综合起来。 1概述在上述情况下,挡土板法立混凝土电杆,需要耗费很多人力,并且劳动条件十分艰苦,施工成本大,也不能解决流水问题,危险性也较大。沉箱法较挡土板法先进,但也不能解决流
When the construction in the quicksand silt area, the excavation is difficult to pit, difficult to form a hole in the quicksand silt area, often collapsed during the construction of digging, dug and collapsed, but also accompanied by water outflow, bringing great difficulties to the construction, There are dangers when digging deeper holes. Currently there are methods of digging the earthwork board method, caisson method, explosive expansion method, but each have hard to solve the defects. Quicksand mud pile hole machine it can baffle method, Caisson method, drilling and other advantages of drilling together. 1 Overview In the above circumstances, the concrete slab Fa Fa Fa legislation, need to spend a lot of manpower, and labor conditions are very difficult, the construction cost is large, it can not solve the problem of flowing water, the risk is also greater. Caisson law more advanced method of soil, but it can not solve the flow
