Furthermore, the diameter of the down-the-hole hammer is equal to that of the double-layer hollow drill rod, and the drill rod and the down-the-hole hammer are designed in the same diameter mode.

The working principle is as follows:

the air compressor compresses air to form high-pressure air, the high-pressure air enters the cavity of the double-layer hollow drill rod and is conveyed into the down-the-hole hammer through the air supply pipeline and the air converter to drive the impactor at the end part of the hammer head to perform piston movement, the aim of impact drilling is achieved, under the action of an air flow and mud residue pumping device, rock debris and mud residues are discharged into a mud pit or other mud residue collecting devices after passing through a slag discharge and filling hole of the down-the-hole hammer, a hollow channel, a three-way pipe and a mud residue pumping device in the double-layer hollow drill rod, when the drilling is carried out to the designed depth and the holes are cleaned, the double-layer hollow drill rod is lifted, filling materials are pumped to the bottom of the drill hole through a pipeline, the three-way pipe, the hollow channel in the double-layer hollow drill rod and the filling and slag discharge hole of the down-the hole hammer through a ground pump, the poured concrete surface is controlled to be higher than a discharge hole at the bottom of the hammer, and the drilling tool is lifted while the filling materials are lifted, so that pressure pouring is formed.

The utility model has the advantages that:

the utility model discloses on the basis of having absorbed current down-the-hole hammer equipment advantage, combine long auger center to press and irritate stake technique and reverse circulation technical principle, integrated reverse circulation technique and the integration equipment of pouring stake technique have been developed, the dual-purpose function of "a hammer has been realized, and need not to follow the pipe or mud dado and creep into, it is clean to clear the hole, the construction rate of having improved and creeping into, reduce other supporting construction equipment, equipment cost has been reduced, it is applicable to all kinds of complicated geological conditions, such as the filling layer of composition extremely inhomogeneous, the boulder layer, the rock drift layer, the stratum that karst (solution ditch, solution tank, solution cavity, crack etc.) developed, groundwater is abundant, the stratum that hard rock need be gone into to borrow stake construction dado difficulty and pile tip etc..
