Abstract
The utility model relates to a multi-functional drilling barrel which comprises a drilling barrel body (1). An upper square opening (2) connected with a rotary excavating drilling rod is arranged on the top of the drilling barrel body (1), a double-opening double-layer base plate (3) with bucket teeth (6) is movably connected on the bottom portion of the drilling barrel body (1), an automatic door-opening connecting rod (4) controlling the bottom double-opening double-layer base plate (3) to be opened is arranged inside the drilling barrel body (1), a hollow channel pipe (5) is arranged in the center of the drilling barrel body (1), and a movable door drilling point (8) is arranged in the center of the bottom of the double-opening double-layer base plate (3). After pile foundation drilling is completed, the rotary excavating drilling rod is lifted by a certain height to enable the movable door drilling point (8) to be separated from the double-opening double-layer base plate (3), and the pressure pouring operation of concrete can be carried out. The multi-functional drilling barrel is reasonable in structure, low in cost, easy and convenient to operate and high in working efficiency, and has wide market prospect.
Description
Technical field
The utility model relates to the rotary digging drilling hole construction field, specifically a kind of multi-functional drilling pipe.
Background technology
At present, revolve that to dig drilling pipe be one of building pile foundation industry equipment commonly used, its effect is to be responsible for boring and scarfing cinder operation when digging pile driving construction revolving, in order to dig to the interior concrete perfusion of the dark backward stake of design stake.But the drilling pipe scarfing cinder is dug in now general revolving stake mouthful must be proposed after complete, otherwise just can't concrete perfusion, so not only increase the engineering time, but also needed mud off or steel cylinder retaining wall, significantly increased construction costs, so existing revolving dug the development that drilling pipe has seriously restricted the pile foundation industry.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of simple in structure, novel in design, can effectively solve to revolve to dig drilling pipe and can only hole and scarfing cinder, multi-functional drilling pipe that can not concrete perfusion.
The technical solution of the utility model is: a kind of multi-functional drilling pipe, comprise the drilling pipe body, described drilling pipe bodies top is provided with the upper square opening that is connected with rotary drill rod, the bottom is connected with the two double walled floor of opening with bucket tooth, inside is provided with the two automatic door opening connecting rods of opening the double walled floor unlatching in control bottom, it is characterized in that: described drilling pipe body center is provided with upper square opening and opens the hollow channel pipe that double walled floor is connected with two, describedly twoly opens double walled floor bottom centre and is provided with the dodge gate apex point.
Described two bottom of opening double walled floor is established the edge and is provided with movable pick.
Described dodge gate apex point is flexibly connected by bolt and two double walled floor bottoms of opening.
Be provided with the fixedly gripper shoe of hollow channel pipe in the described drilling pipe body.
The utility model revolves tradition and digs drilling pipe and improve, and digs drilling pipe inside the hollow channel pipe is set revolving, and it is connected with the hollow duct of rotary drill rod, in two double walled floor bottom centre that open the dodge gate apex point is set simultaneously.When rotary drill rod clockwise rotates, revolve and dig drilling pipe and utilize bucket tooth to carry out bore operation, utilize simultaneously and twoly open double walled floor and carry out the scarfing cinder operation, after pile foundation boring is complete, rotate counterclockwise rotary drill rod and close two double walled floor of opening, then drilling rod is mentioned certain altitude, carry out concrete pressure by two dodge gate apex points of opening double walled floor bottom at the bottom of to stake and fill with operation.This multi-functional drilling pipe has effectively solved rotary drilling digger and can only hole and scarfing cinder, technical barrier that can not concrete perfusion, significantly improved productivity, reduced cost of production, filled with for concrete pressure and bring great convenience, so this revolves and digs drilling pipe and have the wide market space.
