Specific embodiment
The utility model is further described with reference to the accompanying drawings and examples, but is not intended as to the utility model
The foundation of limitation.
The embodiment of the utility model：A kind of band water drilling type threaded bore as shown in attached drawing 1-2, includes drilling rod 2, bores
The head end of bar 2 is connected with screw thread drill bit 3, and 2 head end of drilling rod is connected with handle 1, and 2 inside of drilling rod is hollow water pipe 4, the hollow water pipe
4 extend at screw thread drill bit 3, and screw thread drill bit 3 is equipped with water outlet, and water inlet pipe 5, water inlet pipe 5 and drilling rod are also associated on drilling rod 2
2 hollow water pipe 4 is connected, and 5 other end of water inlet pipe is connect with water pump 15.
In work progress, rotation handle 1 is to drive the screw thread drill bit 3 of bottom to be crept into, and water pump 15 produces while drilling
Raw high pressure water is injected by water inlet pipe 5 in hollow water pipe 4, is then discharged from the water outlet of screw thread drill bit 3, the high pressure of discharge
Water can be used as lubricating fluid and soil layer bating liquor to be injected into drilling, so as to reduce the frictional force between screw thread drill bit 3 and drilling, and
And cause soil softening, so as to facilitate the drilling of screw thread drill bit 3 and drilling at the end of carry brill.
Water storage cylinder 6 is welded on 2 shaft of drilling rod of 1 lower section of handle, 6 stack shell of water storage cylinder is equipped with outside lid 7, with
It is welded with inside lid 8 on concordant 2 shaft of drilling rod in the top of water storage cylinder 6, there are spacing between the lid of medial and lateral, and two lids
Be respectively provided with 1 groove between sub- madial wall, in groove activity be caught in removable cover 9, removable cover 9 is equipped with an inlet opening
10, inlet opening 10 is connect with 5 head end of water inlet pipe, and 2 shaft of drilling rod at water storage cylinder 6 is equipped with limbers 11, and limbers 11 is another
End is connected with hollow water pipe 4.During use, the high pressure water in water inlet pipe 5 is injected into storage from the inlet opening 10 on removable cover 9
In water drum 6, then entered in hollow water pipe 4 from limbers 11.When drilling rod 2 are rotated, due to the head end of removable cover 9
It is that activity is caught in the groove of outboard cover 7 and inside lid 8, therefore when outside lid 7 and the rotation of inside lid 8, activity
Cover board 9 will not be with rotating together, and after removable cover 9 is avoided to follow rotation together, water inlet pipe 5 can be wrapped on drilling rod 2,
