Lateral surface, bullet groove is communicated to air discharge duct.
It is used as further program of the utility model：In the square neck of bayonet socket insertion joint above described.
It is used as the utility model further scheme：It is additionally provided with pin hole, pin hole and sets on the square neck
Connecting bolt is equipped with, impactor is fixedly connected by connecting bolt with square neck.
Compared with prior art, the beneficial effects of the utility model are：
The utility model can be used in weak foundation soil, be not required to mud off, be not required to a large amount of deslagginves, and construction technology is easy, fits
Close and constructed in gravel layer, mud, miscellaneous fill, backfill building waste, pebble layer, because bullet will during construction
The compacted effect that retaining wall is served to hole wall of the waste residue got off is crushed, friction can make hole wall more smooth during cylinder body running, completeer
Whole, so also not resulting in hole wall collapse when drilling rod is extracted, construction quality is easily controlled；
The utility model, without borehole cleaning, can increase substantially operating efficiency in construction, and speed of application is conventional construction
More than 2~3 times of method, substantially reduce the duration, accelerate engineering construction progress, also make construction machinery and artificial synthesis into
Originally substantially reduce；
The utility model is not required to mud off, pollution-free, field construction neatly, borehole cleaning is not required to, to week in application process
Surrounding environment disturbance is small.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Refer in Fig. 1~4, the utility model embodiment, a kind of impact rotating extrusion sealing drill bit, including joint 1, column
2 and bullet 3；Square neck 11 is provided with the joint 1, square neck 11 is connected to impactor 4, the square neck 11
On be additionally provided with pin hole, pin hole and be provided with connecting bolt 12, connecting bolt 12 fixes impactor 4 and square neck 11
Connection；In the square neck 11 of bayonet socket insertion joint 1 above drilling rod 5, the axial rotation for constraining drill bit, then with connection
Latch 12 fixes impactor 4 with joint 1, prevents drill bit from coming off in the course of the work；
The centre position of the square neck 11 is provided with interior air inlet duct 21, the interior insertion column 2 of air inlet duct 21 and taper
Body 3, interior air inlet duct 21 and the interior insertion of gas-distributing channel 32, interior gas-distributing channel 32 is arranged on the inner side of bullet 3, the interior gas-distributing channel 32 with
