Abstract
The invention provides a method for drilling and filling a concrete hollow pile. The method comprises the following steps: drilling by using a long spiral drilling machine; arranging a steel bar cage in a drilled hole; keeping a protection layer between the steel bar cage and a hole wall; filling concrete into the drilled hole; sinking an inner core pipe into the drilled hole and keeping for the first pre-set time; and pulling out the hollow core pipe after second pre-set time to form the concrete hollow pile. The method provided by the invention has the beneficial effects that the inner core pipe is sunk into a concrete pile so that a pile body of the concrete pile and a soil body beside the pile are compacted; meanwhile, the pile diameter of the concrete pile is increased so that the aim of improving the pile bearing force is achieved.
Description
Technical field
The present invention relates to building field, be specifically related to the method for drill-pouring concrete hollow pile.
Background technology
Castinplace pile system refers to and in foundation soil, forms stake holes at engineering site by means such as machine drilling, steel pipe soil compaction or manpower excavations, and place reinforcing cage, concrete perfusion and the stake of making within it, different according to hole forming method, castinplace pile can be divided into several classes such as tube-sinking cast-in-situ pile, bored pile and digging hole filling pile again.Bored pile is by piling method classification and a kind of pile-type of definition.
The pile body of existing bored pile contacts more loose with Pile side soil body, and pile capacity is less.
Summary of the invention
The invention provides a kind of method of drill-pouring concrete hollow pile, comprising: utilize long screw auger to hole; In described boring, lay reinforcing cage, between described reinforcing cage and described hole wall, leave topping; Concrete is poured in described boring; Inner core tube to be sunk in described stake holes and to keep for first scheduled time; After second scheduled time, extract described hollow pipe form concrete hollow pile.
Further, above-mentioned first scheduled time is two hours.
Further, above-mentioned second scheduled time is twenty four hours.
Further, above-mentioned inner core tube outer wall does anti-stick process.
Further, the method for above-mentioned drill-pouring concrete hollow pile, adopts crane or hammering and pulling-out machine described inner core tube are sling or extract in concrete stake, adopts rig or hammering and pulling-out machine described inner core tube vibration to be sunk in described stake holes.
The present invention also provides the another kind of method to drill-pouring concrete hollow pile, comprising: utilize long screw auger to hole; Long screw auger is proposed, in described boring, pours into concrete; In described boring, lay reinforcing cage, between described reinforcing cage and described hole wall, leave topping; Inner core tube to be sunk in described stake holes and to keep for first scheduled time; After second scheduled time, extract described hollow pipe form concrete hollow pile.
Further, above-mentioned first scheduled time is two hours.
Further, above-mentioned second scheduled time is twenty four hours.
Further, above-mentioned inner core tube outer wall does anti-stick process.
Further, the method for above-mentioned drill-pouring concrete hollow pile, adopts crane or hammering and pulling-out machine described inner core tube are sling or extract in concrete stake, adopts rig or hammering and pulling-out machine described inner core tube vibration to be sunk in described stake holes.
Beneficial effect of the present invention is: by inner core tube being sunk in concrete stake, make the pile body of concrete stake and Pile side soil body compacted, also increase the stake footpath of concrete stake, to reach the object improving pile capacity simultaneously.
