Cross jet flow stirring and spraying pile construction equipment and construction method thereof

The invention provides cross jet stirring and spraying pile construction equipment and a construction method thereof.The equipment comprises a drill rod, stirring blades arranged on the drill rod, first spraying blades arranged on the drill rod and second spraying blades arranged below the first spraying blades; the end of the first guniting blade and the end of the second guniting blade are provided with a first guniting nozzle and a second guniting nozzle respectively, the first guniting nozzle and the second guniting nozzle are used for spraying high-pressure grout, and the first guniting nozzle and the second guniting nozzle form a set angle, so that the sprayed grout cuts a soil body and intersects in the soil body. And the distance between the intersection point and the central line of the drill rod is greater than the radius of the stirring blade. By the adoption of the technical scheme, the formed pile body can be constructed close to an underground structure, and the pile forming diameter is definite
