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.
本发明提供了一种交叉喷射流搅喷桩施工设备及其施工方法，所述设备包括钻杆、设置于所述钻杆上的搅拌叶片、设置于所述钻杆上的第一喷浆叶片和设置于所述第一喷浆叶片下方的第二喷浆叶片，所述第一喷浆叶片的端部和所述第二喷浆叶片的端部分别设置有用于喷射高压浆液的第一喷浆嘴和第二喷浆嘴，所述第一喷浆嘴和所述第二喷浆嘴形成一个设定的角度，使得喷出的浆液切割土体并在土体中交汇，且交汇点与所述钻杆中心线的距离大于所述搅拌叶片的半径。采用本发明的技术方案，形成的桩体能够贴近地下构筑物施工且成桩直径明确。
