The application method of the rock-soil layer drilling equipment for building construction comprises the following steps:
S1, when the rock-soil layer drilling equipment for building construction is used, firstly, the rock-soil layer drilling equipment for building construction is moved to a position to be drilled, then, a drilling motor is started to rotate along with a spiral drill rod to drill holes, in the soil layer drilling process, the spiral drill rod and an arc-shaped blade are matched in rotation, drilling can be easily carried out, when the bottom of the spiral drill rod drills to a rock layer position, the drilling speed of the spiral drill rod is reduced, and at the moment, the arc-shaped blade is extruded by the rock layer to slide to the upper part of the spiral drill rod;
s2, synchronously moving the corresponding L-shaped connecting rods in the upward moving process of the arc-shaped blades, so that the upper parts of the L-shaped connecting rods slide in the waist-shaped grooves on the U-shaped guide sleeves with the sliding rods, at the moment, the U-shaped guide sleeves move towards the direction of the impact drill rod, the waist-shaped grooves on the upper parts of the U-shaped guide sleeves slide in a matched manner with the sliding rods on the connecting cross rods, the connecting cross rods move downwards with the adjusting rods, and the adjusting rods pull the adjusting wheels to be lapped on the corrugated surfaces at the tops of the adjusting rings;
S3, in the rotation process of the spiral drill rod, a supporting bearing inner ring, a connecting ring, a supporting sleeve, an adjusting ring and an impact drill rod which are fixedly connected with the inner wall of the adjusting groove cannot rotate along with the spiral drill rod, the two adjusting wheels synchronously rotate along with the spiral drill rod and roll on a corrugated surface at the top of the adjusting ring, and under the action of an adjusting spring, the adjusting ring is made to reciprocate along the supporting sleeve inside the spiral drill rod to impact the surface of a rock layer;
S4, when the two U-shaped guide sleeves relatively move, the two arc-shaped base plates move along with each other and are attached together, when the impact drill rod moves downwards, guide wheels on T-shaped movable rods on two sides of the impact drill rod are propped against the surfaces of the arc-shaped base plates to enable the two T-shaped movable rods to relatively move, at the moment, the hinging rods on the lower parts of the two T-shaped movable rods deflect and prop against the T-shaped compression rods to move downwards, the movable plate at the bottom of the T-shaped compression rods moves downwards, then the strip-shaped blocks move along with the change of the positions of the strip-shaped grooves on the movable plate, one ends of the strip-shaped blocks move out of the impact drill rod with the U-shaped crushing rods, and the strip-shaped blocks are inserted into rock stratum to be crushed;
And S5, finally, after the impact drill rod and the spiral drill rod pass through the rock stratum, the arc-shaped blade is released from the extrusion state, so that the compression spring elastically restores to press the L-shaped connecting rod and the arc-shaped blade to move downwards on the surface of the spiral drill rod, the U-shaped guide sleeve and the adjusting wheel are reset, and then the adjusting spring is lifted and reset with the adjusting ring and the impact drill rod, so that the adjusting wheel cannot be contacted with the adjusting ring in the rotation process, and the impact drilling state is released.
