Excavation section in-situ curing equipment and curing method suitable for soft foundation soil

The invention relates to excavation section in-situ curing equipment and curing method suitable for soft foundation soil. A plurality of foundation piles are buried in a soil layer of an excavation section, injection mechanisms are arranged in cooperation with the foundation piles so as to monitor settlement or deformation in cooperation with sensors of the injection mechanisms, once settlement or deformation occurs, part of curing agents are injected firstly, and then part of curing agents are injected; and then, the adjusting mechanism is used for adjusting, injection and stirring of the curing agent are completed step by step from bottom to top, and then in-situ curing stabilization of the multiple foundation piles and the areas between the multiple foundation piles is achieved. The device has the beneficial effects that the device is particularly suitable for soft foundation soil, construction is stable, curing agent injection is uniform, the condition of the foundation soil is effectively and dynamically
