Detailed description of the invention
With detailed description of the invention, this utility model is further illustrated below in conjunction with the accompanying drawings.
As shown in Fig. 1 to Fig. 5, underwater cast-in-place pile described in the utility model drags for slag drill bit, including drill bit body 1, institute
State drill bit body 1 for hollow structure, be provided with many in the inside of drill bit body 1 hollow and drag for slag tooth bar 2, described in drag for slag tooth bar 2
One end is connected with the inwall of drill bit body 1, and unsettled and towards drill bit body 1 the central area of its other end extends.This practicality is new
Drill bit body 1 in type can be used directly existing drill sleeve, arranges the most therein and drags for slag tooth bar 2 accordingly.
General, it is provided with union joint 3 in the upper end that drill bit body 1 is axial, is provided with brill tooth 4 in lower end.Wherein, tooth 4 is bored
Structure can be various forms, and its effect is primary is for creeping into.This utility model in use, by by union joint 3 and phase
The drive end of the rig answered connects, and makes brill tooth 4 creep into downward.Wherein, when creeping into, drag for slag tooth owing to being provided with
Bar 2, therefore when having bigger cobble, block stone, this cobble or stone etc. will squeeze through to be positioned at after dragging for slag tooth bar 2 and drag for slag tooth bar 2
In the drill bit body 1 of top, when the most later drill bit being risen, can be by dragging for slag tooth bar 2 by corresponding cobble, stone etc.
And pick up, to reach to drag for the purpose of slag.
Wherein, as it has been described above, the effect dragging for slag tooth bar 2 is for dragging for slag, it is however generally that, for the ease of when creeping into, greatly
Can squeeze through when the cobble of volume, block stone and drag for slag tooth bar 2, the most preferably dragging for slag tooth bar 2 is the bar with certain toughness or elasticity
Shape or thin column structure, such as, can be selected for steel wire rope.And when arranging, every is dragged for slag tooth bar 2 and can have certain bending, and
And its bending direction is preferably directed towards the side of union joint 3, specifically can refer to shown in accompanying drawing 4, the benefit so arranged, on the one hand
Beneficially when creeping into, the slag body such as cobble, block stone squeezes through and drags for slag tooth bar 2, is the most also beneficial to, when rising drill bit, drag for slag tooth bar 2
Can preferably pick up slag body.
Certainly, for the above-mentioned particular number dragging for slag tooth bar 2 it is not strictly necessary that, specifically can be according to practical situation
Fixed.In theory, at identical conditions, the quantity dragging for slag tooth bar 2 of setting is the most, and drag for spacing between slag tooth bar 2 with
And tooth bar size is the least, then the volume of the slag body that can pick up is the least, otherwise the volume of the slag body that can pick up is the biggest.It addition, also
Can be provided with one layer or multilamellar in the axial direction of drill bit body 1 drags for slag tooth bar 2, as shown in Figure 4 for be provided with one layer
Drag for the situation of slag tooth bar 2；Certainly drag for slag tooth bar 2 also can arrange the most in the shape of a spiral.Certainly, be positioned on same layer drags for slag
Tooth bar 2 should be provided with many, and many are dragged for the slag tooth bar 2 circumferentially-spaced distribution along drill bit body 1.General, many are dragged for
The size of slag tooth bar 2, length, degree of crook etc. may be configured as different or identical structures, is wherein preferably arranged to identical
Structure.
It addition, at above-mentioned employing steel wire rope as when dragging for slag tooth bar 2, its one end can be welded direct to drill bit body 1
On inwall, allow its other end the most unsettled simultaneously.Furthermore, it is contemplated that steel wire rope is typically mutually twined by the seizing wire that multiply is thinner
Around forming, in order to avoid its generation is loose, the most also a banding part 5 can be cased with respectively at the two ends of steel wire rope, banding part 5
Effect is the end for banding steel wire rope, it is to avoid it is loose.Concrete, can be selected for the nut conduct that size is adaptive with steel wire rope
Banding part 5；Also by welding manner, nut is welded with steel wire rope simultaneously.Certainly, when being provided with banding part 5, as arranged
When having nut, can realize the one of steel wire rope by the nut of wherein one end being welded direct on the inwall of drill bit body 1
End is connected on the inwall of drill bit body 1.
