Construction method for forcibly stirring inclined supporting pile
The invention relates to a construction method for forcibly stirring an inclined supporting pile. When a prefabricated part is pressed in, the inclined supporting pile with the prefabricated part and a stirring pile combined is formed on the periphery of the prefabricated part through drill bit guniting and forcibly stirring. The method is characterized in that a drill bit is inserted into a center hole of a prefabricated part in advance, the drill bit and the prefabricated part are installed on an oblique stirring and pile pressing all-in-one machine, the oblique stirring and pile pressing all-in-one machine is started, the drill bit forcibly stirs obliquely downwards, and during the period, the drill bit continuously sprays concrete to form a stirring pile; and meanwhile, the prefabricated parts are obliquely pressed into the stirring piles by applying pressure to form oblique supporting piles. The method is efficient in construction, large in oblique bearing capacity, free of disturbance in the construction process and particularly suitable for sensitive zones such as complex underground environment, many surrounding existing buildings and subways.
本发明涉及一种强制搅拌斜向支撑桩的施工方法，在压入预制构件的同时在其外围通过钻头喷浆强制搅拌形成预制构件与搅拌桩相结合的斜向支撑桩。其特点是：将钻头预先插入预制构件中心孔中，钻头与预制构件安装在斜向搅拌压桩一体机上，启动斜向搅拌压桩一体机，钻头斜向下强制搅拌，期间钻头不断喷浆,形成搅拌桩，同时预制构件通过加压力斜向压入上述的搅拌桩中形成斜向支撑桩。本发明施工高效，斜向承载能力大，施工过程中无扰动，特别适用于地下环境复杂，周边既有建筑物多，地铁等敏感地带。
