Description
Technical field
The utility model is related to a kind of drilling tool, and in particular to a kind of well-point pipe treatment hole perforate pincers.
Background technology
Well-points dewatering, is a kind of method of artificial dewatering.Therefore also known as " well-point dewatering method ".In excavation of foundation pit
Before, a number of well-point pipe is buried in foundation ditch surrounding, being drawn water using pumping equipment makes dug soil remain drying regime
Method.The method is used in level of ground water construction environment higher, in being earth work, ground and basic engineering construction
One important technique measure, moisture that can be in drainage base soil, promotes soil solidifying, foundation strength is improved, while soil can be reduced
Slope soil body lateral displacement and sedimentation, stable side slope, eliminate quicksand, reduce the protuberance of substrate soil, make to be located at below natural groundwater
Ground and basic engineering construction be avoided that the influence of underground water, there is provided relatively more dry execution conditions, can also reduce earth volume,
Shorten the duration, improve construction quality and ensure construction safety.
, in order to accelerate the speed of fulfiling hole of well-point pipe treatment hole, typically there are two kinds of pore-forming modes at the precipitation initial stage：Electric drill pore-forming, but
It is that can produce flash after drilling, the filter sand cloth to well-point pipe outsourcing causes to damage, and causes well-points dewatering effect on driving birds is not good.Scissors point of a knife
Drilling, speed of fulfiling hole is very slow, and labour intensity is larger, and scissors easily scratches the hand of operator in pore forming process.
Utility model content
For above-mentioned the deficiencies in the prior art, technical problem to be solved in the utility model is：How to provide it is a kind of into
Hole quality is high, and speed is fast, can reduce the well-point pipe treatment hole perforate pincers of labour intensity.
In order to solve the above-mentioned technical problem, the utility model employs following technical scheme：
A kind of well-point pipe treatment hole perforate pincers, it is characterised in that：Including being articulated and connected the caliper to be formed by two clamp handles,
Clamp handle includes the binding clip of front end and the tong arm of rear end, and two relative sides of binding clip are provided with cylinder cutting knife, the bottom of cylinder cutting knife
Portion is fixedly connected on binding clip, and the external diameter of cylinder cutting knife is identical with the diameter of well-point pipe treatment hole to be processed, the length of cylinder cutting knife
Length of the degree more than well-point pipe treatment hole to be processed.
In the utility model, when use, first operate tong arm to open two binding clips, well-point pipe is placed in two binding clips
Centre, then pinch tong arm, make two binding clips be respectively facing well-point pipe direction rotate.During binding clip is rotated, binding clip
On the edge of a knife of cylinder cutting knife can abut on well-point pipe first, continue firmly to pinch tong arm, cylinder cutting knife will be in active force
Under cut out a hole on well-point pipe, the diameter in this hole is just consistent with the external diameter of cylinder cutting knife.Because this hole is logical
Cross what cutting knife cut out, the edge in the hole cut is bright and clean complete, and hole quality is high, situations such as be not in burr, just not
The filter sand cloth of well-point pipe outsourcing can be caused to damage.Other cut hole also only needs firmly to pinch lower tong arm and can just complete, in cut hole
During operator will not also be damaged, improve speed of fulfiling hole and the security for using, reduce labour intensity.
As optimization, pushing block is provided with the cylinder of the cylinder cutting knife, positioned at the cylinder bottom of pushing block and the cylinder cutting knife it
Between be provided with spring, the cylinder bottom of the two ends of spring respectively with pushing block and the cylinder cutting knife is fixedly connected, and spring under normal conditions can
Pushing block is enough set to be flushed with the cylinder cutting knife edge of a knife towards the side side of the cylinder cutting knife edge of a knife.Cylinder cutting knife is in cut hole
Afterwards, the waste material of generation will be entered into the cylinder of cylinder cutting knife, once piling up excessive in cylinder, will cause shadow to follow-up cut hole
Ring, it is necessary to cleaning in time.After pushing block and spring are set, cylinder cutting knife when cut hole, with deepening continuously for the edge of a knife, the edge of a knife
Pushing block is thought that cylinder cutting knife bottom promotes, while spring is compressed by middle waste material with regard to constantly extruding pushing block.Work as knife
Mouth cut through well point tube wall stretch into pipe in after, waste material is cut completely, then without support force, the recoil of spring for now being compressed is pushed away
Dynamic pushing block is moved towards edge of a knife direction, and then pushing block promotes waste material finally to release the edge of a knife again.Without right after so each cut hole
Cylinder cutting knife is cleared up, and improves cut hole efficiency.
Used as optimization, the inwall of the cylinder cutting knife is extended two bar shapeds being oppositely arranged and leads along its axis direction
To groove, the position of pushing block correspondence bar shaped gathering sill is convexly equipped with can be slidably matched along bar shaped gathering sill length direction with it
Guide pad.Can be oriented to for the movement of pushing block, it is to avoid pushing block is stuck in cylinder cutting knife.
Used as optimization, two relative side sides of the binding clip are arranged with semicircle groove respectively, semicircle groove
Radius is identical with the radius of well-point pipe to be processed, when two binding clips are rotated towards relative direction and are mutually abutted together,
Two semicircle grooves can close up the cylinder through hole to be formed and pass through well-point pipe to be processed, and the cylinder cutting knife is located at semicircle
On the bottom land of groove.When cut hole, it is necessary to operator exerts oneself tweezers arm, can have sufficiently large active force in well-point pipe
Upper cut hole, but if without timely control dynamics after the completion of cut hole, two binding clips continue to extrude well-point pipe, and possibility will be right
Well-point pipe causes to damage.Semicircle groove is set on binding clip, after two such binding clip is mutually rotated and abutted together, two
Semicircle groove can form a through hole as the pipe diameter of well point, well-point pipe can just be made to pass through without to well point
Pipe causes to damage.
In sum, the beneficial effects of the utility model are：The utility model simple structure, it is easy to use, cut
The edge in hole is bright and clean complete, and hole quality is high, situations such as be not in burr, in addition will not be to behaviour during cut hole
Author damages, and improves speed of fulfiling hole and the security for using, and reduces labour intensity.
