Multi-layer mutual shearing dry spraying mixing pile drilling machine equipment and construction method
The invention relates to the technical field of underground engineering construction mechanical equipment, in particular to multi-layer mutual shearing dry spraying mixing pile drilling machine equipment and a construction method.The equipment comprises a drilling machine body, a feeding background and a control module, and the feeding background controls all electric control switches and monitors all sensors in real time through the control module. Curing agent powder can be continuously and evenly supplied to the construction drilling machine through the gas material pipeline, the curing agent powder forms a gas-solid two-phase fluid medium in a high-pressure gas injection and pneumatic conveying mode, and the gas-solid two-phase fluid medium passes through the gas material channel of the drill rod and is injected into a foundation soil body through a gas material nozzle formed in the multi-layer mutual shearing stirring drill bit at high pressure. The curing agent powder and the in-situ soil body are fully stirred and mixed to form the dry spraying stirring pile with the pile body being uniformly stirred and high in pile body strength under the staggered layer shearing and stirring action of the multi-layer mutual shearing and stirring drill bit.
本发明涉及地下工程施工机械装备技术领域，一种多层互剪干喷搅拌桩钻机装备及施工方法，该装备包括钻机主体、供料后台和控制模块，供料后台通过控制模块对各电控开关的控制及对各传感器的实时监测。利用气料管道可向施工钻机持续均匀供应固化剂粉料，固化剂粉料通过高压气体喷射和气力输送方式形成气固两相流体介质经过钻杆的气料通道由多层互剪搅拌钻头上设置的气料喷口高压喷射到地基土体中，多层互剪搅拌钻头的错层剪切搅拌作用使固化剂粉料与原位土体充分搅拌混合形成桩体搅拌均匀，桩身强度高的干喷搅拌桩。
