Continuous drilling and cyclic pouring integrated piling tool

Abstract

The invention belongs to the field of constructional engineering and mechanical engineering, and particularly relates to a continuous drilling and cyclic pouring integrated piling tool. According to the technical scheme, the continuous drilling and cyclic pouring integrated piling tool comprises a power connecting piece, a circulating device, a drill bit component, a bottom cleaning mechanism anda pouring mechanism, wherein the circulating device comprises a circulating drilling barrel and a spiral piece, both ends of the circulating drilling barrel are respectively connected with the power connecting piece and the drill bit component or the circulating drilling barrel, and the spiral piece is connected with the circulating drilling barrel; the drill bit component comprises a drill bit base, a drill bit seat and a drill bit, the drill bit seat is connected with the drill bit base, and the drill bit is connected with the drill bit seat; the bottom cleaning mechanism comprises a connecting rod and bottom cleaning blades; and the pouring mechanism comprises a pouring channel and a control piece. The invention provides a novel continuous drilling and cyclic pouring integrated piling tool, and the piling drilling and cyclic chip removal and continuous pouring efficiency is improved.

Description

technical field [0001] The invention belongs to the fields of construction engineering and mechanical engineering, and in particular relates to an integrated piling tool for continuous drilling and cyclic pouring. Background technique [0002] In the piling process of building infrastructure, due to the complexity and unpredictability of geological structures in different regions, the performance requirements of piling tools may not match and lag behind the conditions in the pile well, which will lead to drilling, cuttings removal, and pouring efficiency. Low. The performance of such piling tools cannot meet the needs of efficient piling, because the design of the drill bit structure of the piling machine has not comprehensively considered geological factors such as sandy soil, clayey soil, silty soil, and rock interlayers during the drilling process; The three processes of stopping drilling, lifting the drill barrel and dumping cuttings are carried out in sequence.

Low

The performance of such piling tools cannot meet the needs of efficient piling, because the design of the drill bit structure of the piling machine has not comprehensively considered geological factors such as sandy soil, clayey soil, silty soil, and rock interlayers during the drilling process; The three processes of stopping drilling, lifting the drill barrel and dumping cuttings are carried out in sequence. When operating a deep pile well, the process of lifting the drill barrel and dumping cuttings takes more time, and the drilling and cuttings removal processes are performed alternately. Chip removal circulation mode; the pouring process needs to lift the piling equipment after piling is completed, and replace other special pouring tools in order to realize continuous pouring of concrete

Causes the "intermittent" phenomenon of drilling construction, chip removal circulation, and pouring operations in the hard layer

There is "intermittent" After drilling, it takes more time, financial resources, material resources and manpower
