Novel cast-in-place pile hole collapse prevention construction technology
The invention discloses a novel cast-in-place pile hole collapse prevention construction technology, and relates to the technical field of cast-in-place pile hole collapse prevention. A bearing table is included, a pushing mechanism is arranged on the right side of the bearing table, and a feeding mechanism is arranged on the front side of the bearing table. A propelling mechanism is arranged to be matched with a drill bit to slowly propel a drill rod into a drill hole, in the process, a second motor, a first belt wheel, a first transmission belt and a second belt wheel are matched to drive the drill rod to rotate at a high speed, and a prepared fiber mixture is conveyed into the drill rod from a connecting sleeve through a feeding mechanism; then a third motor, a third belt wheel, a second transmission belt, a fourth belt wheel, a rotating shaft and an auger blade are matched to extrude the fiber mixture downwards and discharge the fiber mixture into a drill hole from a discharge seam, and at the moment, the rotating drill rod can uniformly extrude the fiber mixture onto the inner wall of the drill hole to form a'protection wall ', so that the problem that the inner wall of the drill hole of the cast-in-place pile collapses and collapses is effectively avoided; and the pile body forming quality is improved.
本发明公开了一种新型灌注桩防塌孔施工工艺，涉及灌注桩防塌孔技术领域，包括承托台，所述承托台的右侧设置有推进机构，所述承托台的前侧设置有投料机构。本发明通过设置推进机构配合钻头将钻杆缓慢向钻孔中推进，在此过程中，通过第二电机、第一带轮、第一传动带、第二带轮相配合带动钻杆高速旋转，通过投料机构将制备好的纤维混合料从连接套输送到钻杆内部，然后通过第三电机、第三带轮、第二传动带、第四带轮、转轴和绞龙叶相配合将纤维混合料向下挤压后使其从排料缝中排到钻孔内，此时旋转的钻杆会将其均匀的挤压到钻孔内壁上形成“护壁”，从而有效避免了灌注桩钻孔内壁崩溃坍塌的问题，提高了桩身成型质量。
