According to the technical scheme, the reamer bit integrates the functions of drilling, hole cleaning, reaming and slip casting, pile hole operation can be completed through one-shot drilling, pile forming quality is high, the structure is reasonable, and use is convenient.
Description
Technical field
The utility model relates to a kind of parts of screw pile machine for building, relates to specifically a kind of building long
The screw pile machine reaming bit.
Background technology
At present, high level or building basis adopt reinforced concrete bored pile more, mostly adopt the isometrical stake of long screw pile machine drill in work progress, and the bearing capacity of isometrical stake is poor.For increasing pile capacity, people have expected appropriate location, stake hole is expanded into to bullet, but existing boring drill bit can not meet the requirement of construction.
The Chinese utility model patent that publication number is CN2092595U discloses a kind of bits for rock hole-expending, comprise bit body, fixedly cutlery, pilot bit, axle, on bit body, there are reaming cutlery, reaming cutlery one end to be fixed on the bit body axle with hinge and connecting rod, spline housing can move on splined shaft, splined shaft is fixed on bit body, during bit, the drilling rod axial force makes reaming cutlery radial expansion, drill bit continues to creep into the diameter of expansion, and this reamer can expand the cylindrical expansion bottom outlet of the vertex of a cone that different-diameter and the degree of depth.But this reamer at first will be through the pre-drilled stake of common drill bit hole when carrying out reaming, then expanded bottom outlet by reamer, this drill bit can't a pile, after completing, reaming also needs other concrete perfusion, so just make construction technology further complicated, cost improves, and the engineering time can extend greatly.
The Chinese utility model patent that publication number is CN201220380316.4 discloses a kind of reamer, comprise drilling rod, described drilling rod top connects drill bit, described drilling rod connects fin near an end of drill bit, one end of described fin connects the scraper plate upper end, the other end connecting wing bar of described fin, described fin lower end connects described scraper plate lower end by fixed head, described drilling rod connects one group of helical blade, this reamer main story when creeping into, when reaching the position that needs reaming, reversed, at this moment fin launches reaming is carried out in the stake bottom, at this moment fin gathering of recovery main story after reaming completes, while is concrete perfusion down, realize reaming.This reamer more bit change just can be realized boring and reaming by once creeping into, but after completing, boring also need special concrete perfusion equipment to carry out concrete perfusion, this formation of pile again is brought into the soil of taking out of outside a hole in a hole when drilling rod reverses, outside the soil zone of reaming can't being portalled, can not form reaming, loosened soil is arranged at the bottom of causing on the contrary hole.
The Chinese utility model patent that publication number is CN201460736 discloses China national Department of Intellectual Property and discloses the utility model patent that name is called drilled pressure filling pile slip casting striring bottom expanding drill head, its composition comprises, bit body, oil cylinder is installed in described bit body, described oil cylinder upper end adpting flange, the lower end jointing, connecting cleat below described bit body, in described clamping plate, the subdrilling point is expanded in the installation activity, described bit body comprises steel pipe, on described steel pipe, helical blade is arranged, clutch disk below described steel pipe, described joint is connected connecting rod with described movable the expansion between the subdrilling point, when bore operation, after being bored into projected depth, but the operating cyloinder drivening rod makes two borings expand the subdrilling point to be opened, carry out the major part operation, thereby realize boring, expand, slip casting once completes.This kind of structure meets the function that increases pile body bottom transverse sectional area, than straight stake, can make pile body more firm, but because the reason of structure comes with some shortcomings: l, oil cylinder are arranged in steel pipe, therefore can only carry out the filling of cement or other fluid slurry, if filling concrete slurry, concrete be difficult to by, so filling concrete slurry in entering steel pipe after, because the oil cylinder that exists of sand material obviously can't be expanded outward, and oil cylinder is in filling concrete slurry, easily break down, cause shorten application life; 2, drill bit is when boring downwards, and mud and sandy soil easily enter in steel pipe, and the whereabouts of plugging cement slurry causes pouring into; 3, the expansion subdrilling point that bottom expanding drill is two sheets forms, because it only depends on operating cylinder to support and drives, without other fixation, obviously the intensity of its structure can only be applied and construction in the environment soft in soil property, be difficult to use in soil property or the harder environment of geology, if use, also be very easy to damage, what can't guarantee construction does requirement normally.
