Device type
Piling machinery
Project Introduction:There are high-voltage lines in some areas of the construction site, with a height limit of 18 meters
Construction Equipment:SR175、XR280
Drilling Parameters:Pile diameter: 0.8; Pile depth: 12m
Construction Geology:0~4m is backfill, and 5~12m is strong ~ moderately weathered red sandstone
Construction drill pipe:Sany JSΦ377mm*4*08 machine lock lever
Construction Drill Bucket:Φ 1m sand bucket + Φ 0.8m barrel drill + Φ 0.8m sand bucket
Project Description:Hubei Fengshan construction project with an annual output of 24,500 tons of p-chlorotoluene and other fine chemical products due to the construction under the high-voltage line, the height limit is 18 meters, and the construction environment is limited, requiring low clearance equipment construction
Construction difficulties:There is medium-weathered red sandstone about 4 meters underground, and the general low headroom small equipment cannot be drilled, and the conventional equipment cannot be constructed under the high voltage line
Problem Solving:Sany SR175 drilling rig is used, 1 meter sand bucket is used for 4 meters of backfill layer, and red sandstone below 4 meters is drilled with a barrel drill or sand bucket
Construction Efficiency:The average drilling is 4 meters per hour, and 8 can be drilled 24 hours a day
Construction Fuel Consumption:Fuel consumption is 280 liters a day
