The invention discloses a high-efficiency in-tubular
pile soil drilling,
pile pressing,
powder spraying and
mortar spraying integrated
machine and a construction process thereof. The high-efficiency in-tubular
pile soil drilling, pile pressing,
powder spraying and
mortar spraying integrated
machine comprises a static pile pressing
machine, an upright post, a plurality of hollow
drill rods and a plurality of tubular piles; the static pile pressing machine is provided with a static pile pressing machine base and a carrying table; a double-drum
winch and a rear fixed
pulley are mounted on the rear side of the bottom of the upright post; a front fixed
pulley block is mounted on the front side of the bottom of the upright post; an upper fixed
pulley block is arranged at the top of the upright post; the double-drum
winch, the rear fixed pulley and the upper fixed pulley block are connected with the top of a power device through a first steel
wire rope; connector screw threads are formed in the centre of the bottom of the power device; pressurizing movable pulley blocks are arranged on the two sides of the bottom of the power device; the double-drum
winch is connected with the front fixed pulley block and the pressurizing movable pulley blocks through a second steel
wire rope; connector screw threads are formed in the top and the bottom of each hollow
drill rod; a
drill tip is arranged at the bottom of each hollow drill rod, and a high-pressure
powder injecting and
mortar injecting
pipe connector is arranged at the top of each hollow drill rod; the tubular piles are hung in a pile clamping mechanism. According to the high-efficiency in-tubular pile soil drilling, pile pressing, powder spraying and mortar spraying integrated machine and the construction process thereof, the function of multiple purposes in one machine is realized; the problems of pile
cutting, hole guiding, low
bearing capacity of a single pile and the like caused by the fact that the designed depth cannot be achieved because of geological reasons are solved; differential settlement of a building is avoided.
