The stone-removing drill bit comprises a drill rod, a drill tube, a connector, a steel wire and a slag-removing gate, wherein the drill tube is a cylinder with an opening at the lower end, and the center of the upper end of the drill tube is connected with the connector; the connector is provided with an internal thread; an external thread matched with the size of the internal thread of the connector is arranged at one end of the drill rod, and the drill rod is connected on the connector; a circle of steel wire is arranged at the position close to the lower end in the drill tube and is arranged along the circumferential direction in the drill tube; the slag-removing gate is arranged on a drill tube wall above the steel wire, one side of the slag-removing gate is connected with the drill tube wall by a hinge, and the other side of the slag-removing gate is movably connected with the drill tube wall by a hook.
Description
Technical field
The utility model relates to a kind of bridge drilling stake and gets lapicide's tool.
Technical background
In more existing bridge drilling filling pile constructions, usually adopt auger boring, the constructor is afraid of to run into boulder or mud very much, and these things can make auger turn round, and are difficult to normal boring.Therefore stone or mud need be taken out, but getting stone often lacks handy instrument again.
Summary of the invention
The utility model purpose overcomes above-mentioned existing deficiency exactly, provides a kind of bridge drilling castinplace pile simple in structure, easy to use to get aiguille.
The utility model comprises drilling rod, bores tube, connector, steel wire and clean-out door; Boring tube is the cylindrical shape of lower ending opening, bores tube upper end central authorities and is connected with connector; The structure and the plain nut of connector are close, are provided with internal thread; Drilling rod one end is provided with the external screw thread that matches with connector internal thread size, and drilling rod is contained on the connector by the external screw thread of one end; Bore in the tube and be provided with a circle steel wire near lower end, steel wire is arranged along boring tube inner periphery direction; Be provided with clean-out door on the brill barrel above the steel wire, clean-out door one side is connected with the brill barrel by hinge, and opposite side adopts hook to be connected with the brill barrel is alive.The clean-out door length of side is 30-35 centimetre, and the top is shaped as rectangle from boring 5-8 centimetre of tube upper end.
The utility model is applicable to that the bridge drilling stake runs into geological conditions such as boulder or mud, can eaily stone be taken out in the geology that those augers can't turn round, and guarantees the normal operation of auger; Simple in structure, cost is low, and is easy to use.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1, drilling rod, 2, connector, 3, bore tube, 4, steel wire, 5, clean-out door, 6, hook, 7, hinge.
The specific embodiment
Connector 2 is welded on and bores tube 3 top center positions, can store stone etc. in the brill tube 3, and steel wire 4 can prevent to bore tube 3 interior stones and drop out.Steel wire 4 positions are apart from boring about 20 centimetres of tube 3 bottoms.Earlier drilling rod 1 is connected with connector 2 during use and tightens.To get aiguille and put into boring, the running of startup rig after a few minutes is mentioned drill bit, opens clean-out door 5, draws out and bores a stone and foreign material in the tube 3; Once more drill bit is put into the hole, repeat above-mentioned steps, till not having stone and foreign material.
