Drill bit device, slurry mixing pile machine and construction method of slurry mixing pile machine
The invention is suitable for the technical field of foundation treatment, and discloses a drill bit device, a slurry mixing pile machine and a construction method thereof.The drill bit device comprises two first fixed drill bits, an impact drill bit, an elastic piece, a piston and a first conveying pipeline; the percussion bit is located between the two first fixed bits, a pressing plate is arranged at the rear end of the percussion bit, the percussion bit is connected with the elastic piece through the pressing plate, piston moving cylinders are arranged on the two sides of the percussion bit, movable pistons are arranged in the piston moving cylinders, one ends of the pistons are connected to the pressing plate, and the piston moving cylinders are connected with pressure relief openings. When the other end of the piston moves to the pressure relief opening, the elastic piece can drive the impact drill bit to impact out of the position between the two first fixed drill bits to generate impact. The first conveying pipeline is used for conveying pressure to the piston motion cylinder. The piston drives the pressing plate to compress the elastic piece, the other end of the piston moves to the pressure relief opening to enable the piston movement air cylinder to relieve pressure, the elastic potential energy of the elastic piece can enable the percussion bit to generate impact to crush hard objects, and the pile forming quality is guaranteed.
本申请适用于地基处理技术领域，公开了一种钻头装置、泥浆搅拌桩机及其施工方法，钻头装置包括两个第一固定钻头、冲击钻头、弹性件、活塞和第一输送管道；冲击钻头位于两个第一固定钻头之间，冲击钻头的后端设置有压板并通过压板与弹性件连接，冲击钻头的两侧设置有活塞运动缸，活塞运动缸内设置有能够活动的活塞，活塞的一端连接于压板，活塞运动缸连接有泄压口，当活塞的另一端移动至泄压口时，弹性件能够带动冲击钻头由两个第一固定钻头之间冲出产生冲击；第一输送管道用于输送压力至活塞运动缸。通过活塞驱动压板压缩弹性件，活塞的另一端移动至泄压口使活塞运动气缸泄压后，弹性件的弹性势能可使冲击钻头产生冲击，击碎硬物，保证成桩质量。
