How many meters of construction hole pile can be used for a selection of tile drill from input to scrap, whether it is related to the diameter of hole pile
Rotary excavation life with maintenance, operation, construction geology, pile diameter have a great relationship.Maintenance needless to say, a little common sense of all know.Operation is like adults with children, teach good, just do not learn well, it is waste.The quality of construction geology is also very critical. Just like the 60 year old man, called him one night and three young woman gas Wang ML, certainly fall apart!Pile diameter size and depth: for example, type 220 rotary excavation, the maximum theory is 2 meters 5, depth of 65 meters. But it's really hard to reach. The geology is good. 2 meters will be enough. If you really do 2 meters 5 of the pile, it is like a night can only do 3 times, I'm going to do 5 times, 7 times.
The number of total construction meters you have no way to answer, one day a rotary drilling stem two, three hundred meters to tens of meters are met, the weather situation of non visible suspension, or because of the project department, such as the human shutdown can avoid has probably worthwhile. There is no average monthly number of meters.
Domestic rotary drilling rig under normal maintenance, the use of more than 6 years, almost or even longer. The imported equipment maintenance normal use, I feel more than two decades is not a big problem. However, this does not include the production plant equipment production design of abnormal special circumstances and construction operation is not correct, and accidents.
