External movable jet flow suction type caisson foundation reinforcing device and reinforcing method
The invention relates to the field of civil engineering, in particular to an external movable jet flow suction type caisson foundation reinforcing device and method. The reinforcing device comprises a servo motor, a mud jacking device, a mud jacking pipe, a guide pipe, a movable jet flow nozzle, a lifting device and a barge. A servo motor, a mud jacking device and a lifting device are assembled on the barge; the guide pipe is located in the suction type caisson foundation. The mud jacking device is communicated with the movable jet flow nozzle through a mud jacking pipe; the lifting device is used for lifting the mud jacking pipe, and the movable jet flow nozzle is located in the guide pipe. The invention provides an external movable jet flow suction type caisson foundation reinforcing device. The movable jet flow pipeline is arranged on the side wall, and the mud jacking pipeline is rotationally lifted through the positioning device and the lifting device, so that high-speed slurry continuously cuts soft clay and is stirred to form a cement soil reinforcement body around the suction type caisson foundation, and the horizontal and vertical bearing capacity of the suction type caisson foundation is improved.
本发明涉及土木工程领域，尤其涉及一种外置移动射流吸力式沉箱基础加固装置及加固方法。该加固装置包括伺服电机、压浆装置、压浆管、导向管、移动射流喷嘴、提拉装置、驳船；所述的驳船上装配伺服电机、压浆装置、提拉装置；导向管位于吸力式沉箱基础内；压浆装置通过压浆管与移动射流喷嘴相连通；提拉装置用于提拉压浆管，移动射流喷嘴位于导向管内。本发明提供的外置移动射流吸力式沉箱基础加固装置。侧壁布置移动射流管道，通过定位装置和提拉装置旋转提拉压浆管道，使高速浆液不断切割软黏土，并加以搅拌使吸力式沉箱基础周围形成水泥土加固体，来提高吸力式沉箱基础的水平与竖向承载力。
