The bored pile is a pile formed by mechanically boring a pile hole in foundation soil, placing a steel reinforcement cage therein, and pouring concrete. The construction of cast-in-situ bored piles is divided into two types, namely a slurry wall protection method and a full casing construction method, according to the difference of the selected wall protection. Wherein, the work progress of mud dado drilled pile does: leveling field → slurry preparation → pile casing embedding → working platform laying → drilling machine installation and positioning → drilling hole forming → hole cleaning and hole forming quality inspection → steel reinforcement cage lowering → underwater concrete pouring → pile casing extraction → quality inspection. When using the percussion drill to creep into the pore-forming, need constantly add mud to downthehole and prevent the hole that collapses, simultaneously, supporting mud pond and the sedimentation tank of setting up on work platform carries out mud circulation and takes out the sediment operation. When a plurality of impact drills are adopted for simultaneous operation, in order to adjust slurry indexes in time and ensure the slag discharging effect, the volumes/occupied areas of a slurry tank and a sedimentation tank need to be correspondingly increased. However, when the drilled pile is located in a river or a sea area, the construction platform is an overwater platform, the operation surface of the construction platform is limited, the construction cost can be greatly increased by arranging more mud ponds and sedimentation tanks, the operation can be usually carried out by only adopting one percussion drill, and the overall construction progress of a project is seriously influenced. Secondly, because the sounding pipe height that carries out pile foundation quality inspection is located the pile bolck mostly, and need demolish construction platform, beat the steel sheet pile and just can survey the pile after deep basal pit excavation, if find the pile foundation has quality problems, then need demolish the cofferdam again and set up construction platform and carry out the pile foundation and beat again, will prolong construction period greatly, increase cost simultaneously, the risk factor is too high.
