Efficient waterproof curtain bored pile construction device and process
The invention provides an efficient waterproof curtain bored pile construction device and process. The efficient waterproof curtain bored pile construction device comprises a stand column, and a machine head is slidably mounted at the top of the stand column. A buffer rod is arranged at the outlet end of a high-pressure spray head in the punching structure, a sealing block is arranged at the inner end of the buffer rod, the sealing block is automatically opened in a high-pressure state, and the sealing block can automatically seal the outer side of the high-pressure spray head when a drill rod is mounted and dismounted, so that sludge is prevented from entering and blocking the high-pressure spray head, and the service life of the high-pressure spray head is prolonged. When the drill rod rotates to enter the ground, after the high-pressure spray heads are opened, the buffer rods are automatically opened, the buffer rods play a role in buffering when making contact with hard objects such as stones on the side faces of the drill bit, the high-pressure spray heads are prevented from being collided and damaged, the hard objects such as the stones are pushed to the side faces, and the protection effect on the high-pressure spray heads on the two sides of the drill bit is achieved; the high-pressure spray head can be prevented from being blocked, and meanwhile, after the high-pressure spray head is opened, hard stones and the like can be buffered when the high-pressure spray head rotates.
本申请提供了一种高效止水帷幕钻孔桩施工装置及工艺，包括立柱，所述立柱的顶部滑动安装有机头。在打孔结构中的高压喷头的出口端设置一个缓冲杆，并在缓冲杆的内端设置密封块，在高压状态下，密封块自动打开，在进行钻杆的安装和拆卸时，密封块会自动的对高压喷头的外侧进行密封，从而防止淤泥进入堵塞，在钻杆旋转进入地面的同时，在高压喷头打开后，缓冲杆自动撑开，并通过缓冲杆对钻头侧面的石头等硬物接触时起到缓冲作用，防止高压喷头碰撞损坏，并将石头等硬物推到侧面，实现了对钻头两侧高压喷头的保护作用，不仅可以防止高压喷头被堵塞，同时在高压喷头打开后，在转动时可以对硬石等起到缓冲作用。
