Common spiral drilling machine is widely used a kind of auger in builing industry.This rig can only be finished boring work merely, and pile proposes drilling tool often, again concrete placing.Thereby efficient is low, can't handle the hole that collapses, and supporting capacity is not high yet.There are two kinds of new rigs to come out in recent years, the drilled pressure filling rig that first Chinese patent ZL86100705 is adopted, it two is " helical driller for concrete perfusion " that the disclosed Chinese invention patent CN1076980 of application is provided.Though first kind of rig solved and bored the hole do not put forward just can the spray problem of cement paste of brill in the hole, because perfusion is not concrete, can only the later stage people throw in building stones, mends slurry then.Therefore, the building stones uniformity of mixing with cement paste is uncontrollable.Not really high because of there not being the intensity of husky material pile body own, the lapidation material often has a large amount of slurries to overflow in addition, has both wasted cement, pollutes on-the-spot again.Second kind of rig can carried concrete perfusion when boring, and pile body self intensity is guaranteed usually.But because of the auger bottom is a open space on the screw, so can not apply very big pressure, cement paste is little to the osmotic effect of Tu Bi.Also owing to the geological conditions difference, the cement paste in the concrete is also different to the hole wall seepage discharge, causes pile body different parts mix proportion example different, causes the strength of the mixing pile instability, and reinforcing cage can't insert when serious, makes the technology failure.
After order of the present utility model is the native pore-forming of a kind of brill of design, can be with water under high pressure mud spray-hole wall, press down perfusion attitude concrete at closed state, simultaneously the rig of forcibly cement paste of ejection and part concrete being smeared a bored pile that is pressed into sidewall repeatedly through pressure plate.
The utility model includes drill body, cement paste carrier pipe, elephant trunk, the output gear of reduction box, top cover, bearing, sealing ring, and it also includes pressure plate, plate valve, last bottom valve, following bottom valve.The drill body bottom is two helical blades, is fixed with pressure plate on the outer rim of helical blade, and pressure plate is the curved surface plank frame, and the close neighbour of native sidewall of pressure plate and cylindrical hole has a little angle having at least on the pressure plate between a place and the hole wall.When pressure plate rises with drill body rotation, can smear forcibly and be pressed into Tu Bizhong entering material (soil, cement paste, concrete) in the angle.
Be provided with a plate valve in the pitch of single the helical blade in pressure plate upper end, plate valve has two stable status, opens and closes.Plate valve is parallel with hole wall when open, does not influence unearthed.Be drilled into desired depth, drive the control lever on drill body top, under a spring action and a side material pressure plate valve cuts out, the sealing threaded hole is carried out guncreting.
In the following outlet of elephant trunk, be provided with the following bottom valve made from disposable fragile material, by stay cord and a depression bar that is located at elephant trunk upper end an end link to each other.Be provided with bottom valve on again in the elephant trunk above the bottom valve down, a control swing handle is stretched out in the side of last bottom valve.
The utility model is after being drilled into desired depth, and drilling rod continues (in the same way or oppositely) rotation, and by to the hole wall gunite, the mixing of pressure injection doubted the soil part and poured into hole wall from the opening of concave surface, and pressure plate forces to smear repeatedly pressure with cement and part concrete to hole wall.The adhesion of concrete pile body and hole wall is greatly improved.And because of hole wall has fully absorbed cement paste, the cement paste in the pile body concrete no longer exosmoses, and makes the pile body mix proportion keep stable, can guarantee that the intensity of pile body and reinforcing cage are easy to insert.In addition, because of having realized sealing pressure injection concrete basically, can make the pile body hole enlargement and improve pile strength.This pile forming machine is applicable to clay, sandy soil, mucky soil, has or not phreatic all kinds of geological conditions.And do not have mud, cement paste is excessive, pile intensity height, mechanization of operation degree height, low, the cleaned in situ of cost.
