Excavation supporting drilling bored concrete pile construction equipment

The utility model relates to a technical field of excavation supporting drilling bored concrete pile discloses excavation supporting drilling bored concrete pile construction equipment, including excavation supporting drilling bored concrete pile construction equipment bore in the soil layer soil layer hole dig soon in drilling tool, the embedding soil layer hole protect a section of thick bamboo, will protect section of thick bamboo embedding maybe will protect vibration hammer that a section of thick bamboo pulled out from the soil layer hole in the soil layer hole, be arranged in the basement rock layer bore the basement rock hole the down -the -hole hammer, be used for toward the air compressor machine of downthehole air supply and to the hole of injection mud go on hole clearly take the pick dig the rig soon. When the pore -forming, adopt and to dig the drilling tool soon and carry out the trompil, and utilize and protect a dado, the problem of can prevent to collapse hole and hole undergauge, utilizing the air supply of down -the -hole hammer cooperation air compressor machine, having superstrong broken rock ability, when the hard -rock boring, one gets into the end, and last, the adoption is dug the rig soon and is carried out hole clearly for speed of fulfilling hole accelerates greatly, accelerates the construction progress, avoids the pore -forming in -process to produce a large amount of mud waste residues again, realizes the green construction, practices thrift the cost.
