Variable-strength variable-cross-section cement-soil slurry spraying pile and drilling, stirring and spraying integrated construction method
The invention discloses a variable-strength variable-cross-section cement-soil slurry spraying pile and a drilling, stirring and spraying integrated construction method.The variable-strength variable-cross-section cement-soil slurry spraying pile comprises a large-diameter section, a transition section and a small-diameter section, and the large-diameter section and the small-diameter section are in transition through the transition section; the large-diameter section is a variable-strength grout spraying pile, and the small-diameter section is a high-pressure splitting grout spraying pile. The transition section is an integrated pile formed by simultaneous construction of jet stirring and high-pressure splitting stirring.
本发明公开了一种变强度变截面水泥土浆喷桩及钻搅喷一体施工方法，变强度变截面水泥土浆喷桩包括大直径段、过渡段和小直径段，所述的大直径段与小直径段之间通过过渡段过渡；且大直径段为变强度浆喷桩，小直径段为高压劈裂浆喷桩。所述的过渡段为喷射搅拌和高压劈裂搅拌同时施工形成的一体桩。
