Description
Technical field
The invention belongs to poured pile base technical field in architectural engineering, and in particular to bored concrete pile boulder rapid cleaning device and
Its construction technology.
Background technology
During the Wharf Construction of riverside, access bridge root need arrange several bent foundations, access bridge perpendicular to embankment simultaneously
Drop-over, in the range of embankment along the Yangtze dumped rocks protecting foundation, riprap layer thickness is filled about in 5m or so for access bridge part bored concrete pile region
Note stake stake is long from 40-54m, is both needed to penetrate existing embankment riprap layer during drilling construction, before bored concrete pile putting up platform waterborne, makes
Construction of removing obstacles is carried out to the jackstone of grout pile position near zone with grab bucket dredger, depth of removing obstacles is more than 5m, jackstone
Remove obstacles and use DZ60 vibration hammer sinking steel φ 1300mm casings after construction, sinking steel protecting canister construction is smooth, all steel pile castings under
Sink to position.
But on the water putting up platform is completed, convolution rig starts to find still have at the bored concrete pile hole position of part during drilling construction
Boulder is present, depth 10m or so about under mud face, size about 50cm or so, and common GPS type convolution rig cannot be penetrated or broken
Broken boulder, need to adopt additive method drilling and forming hole, and in this case, conventional use of is punching piling machine pore-forming, and punching is beaten
Stake machine is to lift block stamp to eminence using hoist engine, then block stamp is reached boulder by boulder in freely falling body impact opening
The purpose to hole wall is extruded after broken, rotary drill machine machine is gained again after huge stone handling is finished and is continued to creep into.
But do not consider that punching is beaten at the beginning of being bored concrete pile waterborne, bored concrete pile Platform Designing waterborne due to engineering bored concrete pile major part
Stake machine load, if so using punching pile driving equipment, needing to carry out existing bored concrete pile platform consolidation process, needs expend a large amount of
Manually, material cost and duration need to lengthen, using convolution rig in the case of affecting without boulder, the pore-forming time is about 20 to bored concrete pile
Hour or so, if meeting be about 70 hours or so using the punching piling machine pore-forming time after boulder, single stake pore-forming is beaten using punching
Stake machine rubble need to increase the process time of 50 hours, not meet the construction period of engineering, also considerably increase cost of labor and set
Standby lease expenses.So being badly in need of finding a kind of new boulder liquidating plan.
The content of the invention
To solve the above problems, the invention discloses bored concrete pile boulder rapid cleaning device, rational in infrastructure, it is easy to use,
Without using piling machine, short time limit, low cost is practical.
To reach above-mentioned purpose, technical scheme is as follows:
Bored concrete pile boulder rapid cleaning device, it is characterised in that:Including drilling pipe and steel wire comb, the drilling pipe is both ends open
Cylindrical structural, drilling pipe top is provided with adpting flange two in the middle of top board, top board, and connection force rod, described in the middle of the flange two
Grout hole is provided with the middle of force rod, force rod top is down extended in drilling pipe by the jointed rod of flange one, force rod lower section
Portion, is provided with floor between top board side and drilling pipe inwall, drilling pipe bottom is provided with 4-10 alloy bit, and the steel wire comb sets
The lower section inside drilling pipe is put, steel wire comb is divided into upper and lower two-layer, and every layer of steel wire comb is made up of 10-30 root steel wire ropes, owned
Steel wire rope afterbody is uniformly arranged on drilling pipe inwall, and the head of steel wire rope is directed at drilling pipe axis, and rope capacity is less than drilling pipe
Radius, steel wire comb intermediate formation dress stone hole.
Used as a modification of the present invention, the alloy bit of the drilling pipe bottom is highly 3cm.
Used as a modification of the present invention, the every wirerope diameter is 32mm.
Used as a modification of the present invention, the top board crosses anchor bolts with flange two-way.
Used as a modification of the present invention, the grout hole internal diameter is 180mm.
As a modification of the present invention, a diameter of 150mm in the dress stone hole.
Used as a modification of the present invention, the top board is cydariform.
The construction technology of bored concrete pile boulder rapid cleaning device, comprises the following steps:
(1)It was found that there is stone at priming concrete pile hole bottom, drilling pipe is filled to into former convolution drill bit of drilling machine position, drives drilling rod to allow by mill
Drilling pipe is rotated, 20-30 rev/min of rotating speed;
(2)Convolution rig applies pressure to drilling pipe, and down, the block stone of bottom hole is pressed in drilling pipe drilling pipe after steel wire comb;
(3)Steel wire comb has blocked stone toward falling when carrying brill, so as to serve from bottom hole the effect for drawing stone.
The invention has the beneficial effects as follows:
Bored concrete pile boulder rapid cleaning device of the present invention, can quickly clear up boulder, especially few to small volume, quantity
Boulder has significant effect, grabs stone quickly effectively, and its device fabrication low cost, easy to operate, is not required to more during due to using
Change rig, it is only necessary to change drilling pipe, compared with punching piling machine pore-forming efficiency is substantially increased, the pore-forming time is about 30 hours left sides
The right side, compared with the punching piling machine pore-forming time about 40 hours are shortened, and the duration shortens, and efficiency is improved, practical.
During construction, drilling pipe rotation is down pressed into the stone at priming concrete pile hole bottom after steel wire comb in drilling pipe, due to
Drilling pipe constantly rotates, and stone can disperse to be attached on inwall under the influence of centrifugal force in press-in drilling pipe, will not all be flocked on dress
At stone hole, therefore stone has entered just out to play a part of quickly to clear up stone.
