Application of Dual-Power Down-The-Hole Hammer Bored Pile in Construction Engineering
In pile foundation construction,the use of drilling cast-in-place pile mud wall construction will create environmental pollution.Besides,the pile construction of tamping,extrusion and vibration will also produce serious disturbance to the surrounding strata,and cause damage to the surrounding buildings.To solve these problems that long plagued the pile industry,the dual-power multi-function drill has been proposed.The combination of the dual-power multi-function drill and the large diameter drilling hole hammer has the advantages of large-diameter rock penetration with high efficiency and no mud pollution discharge,enabling green and environmentally friendly construction.In addition,after the configuration of the corresponding auxiliary devices and equipment,it can also be used to press prefabricated pile,implant prefabricated pile,improve and reinforce deep mixing soft soil,and construct cement mixed soil continuous wall.This paper discussed and analyzed the application of dual-power down-the-hole hammer bored piles in construction engineering.
