Abstract
The utility model discloses a cover bores to salvage handles bury drills device relates to bridge engineering construction technical field, bore the drill bit including cover barrel drill pole and cover, cover barrel drill pole is greater than the hollow steel pipe of bury drills drilling rod for the diameter, and the cover bores the drill bit and is greater than the hollow steel cylinder of bury drills drill bit for the diameter, and cover barrel drill pole bores the drill bit intercommunication with the cover, and the cover bores before the hollow steel cylinder of drill bit the terminal surface and distributes along the axial and has a plurality of scraper tool bits. The utility model relates to a cover bores to salvage handles bury drills device that safe risk is little, the efficiency is high is under construction.
Description
Technical field
This utility model relates to Bridge Construction technical field, bores salvaging in particular to one set and processes burying device, in order to use set drill bit to be mentioned by burying drill bit by Clothoid type fisher after clearing up the burying soil body after drilled pile burying.
Background technology
Major part bridge foundation all uses cast-in-situ bored pile at present, and along with the continuous increase of bridge span, drilled pile also develops towards major diameter, ultra-long pile direction.Boring procedure has many uncertain factors, and rate of penetration, mud index, casing construction quality etc. control improper all to cause collapse hole burying.Conventional burying processes has large-scale floating crane to pull out by force the methods etc. such as method, underwater demolition method, impact broken, the Freezing stratum as rapid process of brill.This type of method all has the feature causing secondary injury risk big.
Utility model content
The purpose of this utility model is: for the deficiencies in the prior art, proposes the set that a kind of construction safety risk is little, effect is high and bores salvaging process burying device.
The purpose of this utility model is realized by following technical proposals:
A kind of set bores salvaging and processes burying device, including set cylinder drill pipe and set drill bit, set cylinder drill pipe is the hollow steel pipe that diameter is more than burying drilling rod, set drill bit is the hollow steel cylinder that diameter is more than burying drill bit, set cylinder drill pipe and set drill bit connect, and the hollow steel cylinder front end face that overlaps drill bit axially distributed have some scrape jet blade.
As selection, connected by transition connecting apparatus between set cylinder drill pipe and set drill bit, transition connecting apparatus internal diameter mates with burying drilling rod external diameter, in order to set cylinder drill pipe and set drill bit are carried out spacing and guide, make to overlap cylinder drill pipe and set drill bit accurate positioning during rotary drilling, do not occur the most shimmy.
As selecting further, set cylinder drill pipe internal diameter is big 50 ± 5cm than burying drill pipe diameter, and transition connecting apparatus internal diameter is than the burying big 5 ± 2cm of drilling rod flange.
As selection, set drill bit internal diameter is big 5 ± 2cm than burying bit diameter.
Aforementioned this utility model main formula case and each further selection scheme thereof can be with independent assortment to form multiple schemes; it is this utility model can use and claimed scheme: such as this utility model; each selection can select combination in any with other; those skilled in the art can understand there is multiple combination according to prior art and common knowledge after understanding the present invention program; it is the claimed technical scheme of this utility model, does not do at this exhaustive.
Workflow of the present utility model: this patent overlaps cylinder drill pipe upper end in use and is connected with ordi-nary drilling machine drilling rod, utilizes gas lift reverse circulation hydraulic pressure convolution rig to drive.This drill bit is used to be salvaged by drill bit after being discharged outside boring by gas lift reverse circulation mode by the burying soil body.Idiographic flow is as follows:
(1) conventional bit and drilling rod is utilized to hole to 1m position, burying drilling rod top.
(2) carry brill, change this patent set drill bit and set cylinder drill pipe continues to creep into.Set drill bit creeps into n ear at the bottom of burying drill bit, machines away the bit freezing thing of burying drill bit surrounding.It is controlled to above about the 1.5m of absolute altitude at the bottom of burying drill bit according to final cleaning.
(3) lift lug drill bit, lower locator determines concrete orientation, burying drilling rod top and absolute altitude.After transfer conventional Clothoid type fisher and entangle burying drilling rod top, utilize rig to promote section by section and portal.
The beneficial effects of the utility model: the feature that simple in construction, construction safety risk are little, construction cost is low, cost solution drilled pile burying that can be less processes problem.

Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, this utility model is further described.
With reference to shown in Fig. 1,2,3, a kind of set bores salvaging and processes burying device, including set cylinder drill pipe 6 and set drill bit 8, set cylinder drill pipe 6 is more than the hollow steel pipe of burying drilling rod 7 for diameter, set drill bit 8 is more than the hollow steel cylinder of burying drill bit 9 for diameter, set cylinder drill pipe 6 and set drill bit 8 connect, and the hollow steel cylinder front end face that overlaps drill bit 8 axially distributed have some scrape jet blade 10.As selection, as shown in this embodiment, being connected by transition connecting apparatus 11 between set cylinder drill pipe 6 and set drill bit 8, transition connecting apparatus 11 internal diameter mates with burying drilling rod 7 external diameter.Set cylinder drill pipe 6 internal diameter is than the burying drilling rod 7 big 50 ± 5cm of diameter, and transition connecting apparatus 11 internal diameter is than the burying drilling rod 7 big 5 ± 2cm of flange.Set drill bit 8 internal diameter, than the burying drill bit 9 big 5 ± 2cm of diameter, is finally drilled into burying drill bit 9 end absolute altitude 50 ± more than 5cm.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all any amendment, equivalent and improvement etc. made within spirit of the present utility model and principle, within should be included in protection domain of the present utility model.
