Abstract
The invention discloses a kind of drill bits of ultra-thin water-stop curtain with ribbing, its main feature is that the bottom of drilling rod is vertically disposed drill bit equipped with hydraulic motor, and with drilling rod, the whirl spraying pipe is vertical connect with whirl spraying pipe by right-angle elbow pipe；The hydraulic motor is driven by the oil line pipe connected, is engaged by output gear with end gear, and drill bit rotation is driven, and carries out the jet mixing perpendicular to drilling rod to the soil body by several spouts in drill bit.The present invention has structure simple compared with prior art, construction for ultra-thin water-stop curtain with ribbing, cement slurry is fully used, construction drill can adjust the length of single width water-stop curtain according to pressure size, reduce lap joint, the construction quality for effectively improving water-stop curtain further lowers engineering cost, improves Business Economic Benefit.
Description
Technical field
The present invention relates to pile foundation and drilling rig technique field, especially a kind of whirl spraying for ultra-thin water-stop curtain with ribbing is bored
Head.
Background technique
When foundation pit is in level of ground water or less, need precipitation with the water in the drainage soil body convenient for earth excavation, but if all
Surrounding environment is complicated, then needs setting water-stop curtain, has an impact to prevent underground water leakage to surrounding enviroment.Currently, conventional sealing
Curtain is generally used the water-seal piles such as Double shaft stirring stake, three axes agitating pile, high-pressure rotary jet grouting pile, MJS, RJP.
The water-stop curtain of the prior art, water-seal pile are that circle one circle of overlap joint forms, and lap joint is more, and
Single diameter of a circle, which reaches great talent, can guarantee the effective thickness of water-stop curtain, therefore, certain waste of material be caused, so that project cost
Height, it is long in time limit.
Summary of the invention
The purpose of the present invention is the whirl spraying brills of the ultra-thin water-stop curtain with ribbing of one kind that provide in view of the deficiencies of the prior art
Head, the drill bit structure driven using drilling rod bottom setting hydraulic motor, carries out the jet mixing perpendicular to drilling rod to the soil body,
For the construction of ultra-thin water-stop curtain with ribbing, cement slurry can be saved, increases the rigidity of water-stop curtain, reduces construction joint, effectively
The construction quality of water-stop curtain is improved, short time limit further lowers engineering cost, improves Business Economic Benefit.
The object of the present invention is achieved like this: a kind of drill bit of ultra-thin water-stop curtain with ribbing, including is sleeved on brill
Whirl spraying pipe in bar, and its drill bit being arranged on whirl spraying pipe, its main feature is that the bottom of drilling rod is equipped with hydraulic motor, and
It is vertically disposed drill bit with drilling rod, the drill bit is engaged by end gear with the output gear of hydraulic motor；Institute
It is vertical connect with whirl spraying pipe that whirl spraying pipe, which is stated, by right-angle elbow pipe；The hydraulic motor is driven by the oil line pipe connected, by defeated
Gear is engaged with end gear out, drives drill bit rotation, and carried out vertically to the soil body by several spouts in drill bit
In the jet mixing of drilling rod.
The drilling rod bottom is equipped with mud valve.
The present invention has structure simple compared with prior art, easy to use, and water-stop curtain is equal thickness seepproof screen with ribbing, water
Mud is fully used, and water-stop curtain is protruded in pilot hole part, can increase the rigidity of water-stop curtain, construction drill can basis
Pressure size adjusts the length of single width water-stop curtain, reduces lap joint, effectively improves the construction quality of water-stop curtain, duration
It is short, further lower engineering cost, improves Business Economic Benefit.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention；
Fig. 2 is appearance diagram of the present invention.
Specific embodiment
Refering to attached drawing 1, the present invention includes the whirl spraying pipe 5 being sleeved in drilling rod 1, oil line pipe 42, and its is arranged in whirl spraying
Drill bit 2 on pipe 5, the bottom of the drilling rod 1 are vertically disposed drill bit equipped with hydraulic motor 4, and with drilling rod 1
2, the drill bit 2 is engaged by end gear 21 with the output gear 41 of hydraulic motor 4；The whirl spraying pipe 5 is by right-angle elbow pipe
51 connect with whirl spraying pipe 5 to be vertical；The hydraulic motor 4 is driven by the oil line pipe 42 connected, is engaged by output gear 41
End gear 21 drive drill bit 2 to rotate, and several spouts 22 by being arranged in drill bit 2 soil body is carried out it is vertical
In the jet mixing of drilling rod 1.
Refering to attached drawing 2,1 bottom of drilling rod is equipped with mud valve 3.
The present invention can adjust the length of single width water-stop curtain according to pressure size, reduce lap joint, guarantee applying for water-stop curtain
Working medium amount, the construction cement slurry for ultra-thin water-stop curtain with ribbing, which can be obtained, to be made full use of.It is above only to the present invention make into
One step explanation is not intended to limit the invention patent, and all is equivalence enforcement of the present invention, is intended to be limited solely by the right of the invention patent
Within claimed range.
