Abstract
It the utility model is related to a kind of underwater pile secondary pile hole cleaning device, including conduit and air compressor machine, conduit is placed in stake holes, conduit lower end is apart from the 60cm of stake holes bottom sediment layer 40, air compressor machine is arranged on pile hole construction platform, conduit upper end connects a horizontal residue outlet, an air admission hole is set at conduit lower end 1/3 on duct wall, the airduct of air compressor machine is connected with supravasal air admission hole.
Description
Technical field
It the utility model is related to underwater pile technical field of construction, and in particular to a kind of underwater pile secondary pile hole cleaning device.
Background technology
Underwater pile secondary pile hole cleaning is most important to the quality of pile foundation, and especially end-bearing pile requires that inner hole deposition slag thickness is no more than
5cm.The method of borehole cleaning mainly drags for slag method and changes slurry processes at present.Circulatory pool need not be set by dragging for slag method borehole cleaning, save area occupied,
Also ensure that river course is not contaminated, but it is slow to drag for slag method borehole cleaning speed, and be not easy clear clean, be not suitable for end-bearing pile.Change slurry processes
Soft Soil Layer and sandy soil matter suitable for suitable collapse hole, retaining wall is carried out by mud, can ensure that pile foundation not collapse hole.Current changes slurry processes
Use direct circulation mode, typical such as Chinese Patent Application No. 201310164070.6, entitled " drilled pile pile foundation is secondary clear more
Hole cleaning device disclosed in aperture apparatus and borehole cleaning method ", one clear water pressurizer is installed in conduit upper end, by clear water pressurizer through leading
Pipe while into stake holes injected clear water one side injecting compressed air, make bottom hole the dregs of society gain an upper hand and rise after being mixed with mud by stake holes
Mouth overflows.Direct circulation mode mud circulation rate is slow, and borehole cleaning efficiency is low, and borehole cleaning is not also thorough, influences pile foundation pouring quality.
The content of the invention
The purpose of this utility model is for problem present in the construction of current pile foundation secondary pile hole cleaning, there is provided a kind of borehole cleaning
Speed is fast, borehole cleaning thoroughly underwater pile secondary pile hole cleaning device.
The technical solution of the utility model is as follows：
A kind of underwater pile secondary pile hole cleaning device, including conduit and air compressor machine, conduit are placed in stake holes, conduit lower end distance
Stake holes bottom sediment layer 40-60cm, air compressor machine are arranged on pile hole construction platform, it is characterised in that：The conduit upper end connection
One horizontal residue outlet, sets an air admission hole on duct wall at conduit lower end 1/3, on the airduct and conduit of the air compressor machine
Air admission hole be connected.
The utility model is simple in construction, and cost is low, and using reacting cycle mode, borehole cleaning speed is fast, and borehole cleaning is thorough.This practicality is new
Supravasal air inlet bore dia through repetition test, is arranged to 5cm, air compressor machine uses 17 cubes with mo(u)ld top half by type in the specific implementation
Number, optimal borehole cleaning effect can be reached, it is zero that can control bottom hole sediment thickness, effective guarantee pile foundation pouring quality.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in figure 1, the utility model includes conduit 1 and air compressor machine 2, conduit is placed in stake holes 3, the lower end distance of conduit 1
Stake holes bottom sediment layer 40-60cm, air compressor machine 2 are arranged on pile hole construction platform 4, and the conduit upper end connection one is horizontal to go out
Slag pipe 5, an air admission hole, airduct 6 and the supravasal air inlet of the air compressor machine 2 are set on duct wall at conduit lower end 1/3
Hole is connected.
During utility model works, the compressed air of air compressor machine 2 enters conduit 1 through airduct 6, in the sky that conduit bottom is formed
Gas is less than mud density in hole with slurry mixture density, and negative pressuren zone is formed in conduit, makes the mixing of hole bottom slurry and sediment
Thing rises along conduit, is finally discharged through scum pipe；During Specific construction, it can be exported in scum pipe and set slag basket 7, can avoided to river course
Pollute；The sediment and slurry mixture of discharge precipitation, filtering in slag basket 7, can to prevent that mud head is too small in hole
Mud after filtering is reinjected in hole, or premium mud will be supplemented into hole with slush pump, forms reverse circulation system.
When the utility model is specifically used, through repetition test, supravasal air inlet bore dia is arranged to 5cm, and air compressor machine is adopted
With more than 17 cubes models, it is zero that can control bottom hole sediment thickness, reaches optimal borehole cleaning effect.
