Construction method of high-pressure jet grouting pile in water-rich quicksand layer geology
The invention relates to the technical field of building construction, in particular to a construction method of a high-pressure jet grouting pile in the water-rich quicksand layer geology. The drilling and spraying integrated construction method is used for drilling and rotary spraying with slurry, the construction principle of rotary spraying and slurry spraying from top to bottom is combined with a low-pressure slurry supplementing mode in the water-rich quicksand layer geology, the phenomena of hole collapse, drill jamming and drill burying are well controlled, and the method has the advantages of being short in construction period, high in safety performance, maximized in economic benefit, capable of saving wall protection materials, high in pile forming quality and the like. The method is suitable for various high-activity permeable layers and is applied to urban construction with high environmental protection requirements.
本发明涉及建筑施工技术领域，具体是一种高压旋喷桩在富水流砂层地质中的施工方法。钻喷一体施工法进行钻孔并带浆旋喷，在富水流沙层地质采取自上而下旋喷喷浆的施工原理结合低压补浆方式，很好地控制了塌孔卡钻埋钻现象，该方法具有施工周期短，安全性能高，经济效益最大化，节约护壁材料且成桩质量高等特点，其适用于各类高活动性透水层，应用于环保要求高的城市建设中。
