Method for lifting, leveling and repairing terrace of soft soil foundation and lifting structure thereof
A method for lifting, leveling and repairing the terrace of a soft soil foundation and a lifting structure thereof are provided. The lifting structure comprises a terrace (5) in which multiple lifting holes (1) are arranged through drilling, concrete bases (7), multiple anchor rods (6) implanted into the terrace (5) around the lifting holes (1), lifting counterforce frames (9), jacks (8) used to jack the lifting counterforce frames (9), and reinforcing piles (16). Each lifting counterforce frame (9) is fixedly connected with the anchor rods (6) around the corresponding lifting hole (1). A soft soil base layer (21) is arranged under the terrace (5), and a hard soil layer (22) is arranged under the soft soil base layer (21). The reinforcing piles (16) are arranged in the soft soil base layer (21) under the lifting holes (1) through drilling and extend into the hard soil layer (22). Each concrete base (7) is placed on the top of the corresponding reinforcing pile (16). Each jack (8) is supported on the top of the corresponding concrete base (7), and abuts against the bottom of the corresponding lifting counterforce frame (9). The method and the lifting structure have the advantages of good repair effect, convenient construction, and realization of construction on a soft soil foundation.
