[0002] Structural reinforcement refers to the strengthening and transformation of existing building structures to improve their bearing capacity, durability and safety to meet new usage requirements or seismic fortification standards.
[0003] The common cement mixing pile reinforcement structure of soft soil foundation generally utilizes the cooperation of rotating mixing drill rod and grouting drill rod to thoroughly mix the soft stratum with cement slurry to form a nail-shaped mixing pile body for reinforcement. When injecting cement slurry into the soft soil, the soft soil is first drilled by the drill rod, and then the cement slurry is stirred and mixed in the aggregate hopper. After the mixing is completed, it is injected into the drill rod and sprayed into the hole through a mortar pump. However, since the amount of cement slurry stored in the aggregate hopper is fixed and the cement slurry in the aggregate hopper is insufficient, the cement slurry injected into the soft soil will break, resulting in soil being mixed in the reinforcement device, reducing the firmness of the reinforcement device.
