Abstract

The invention discloses a bridge pier column deviation rectifying method for a soft soil foundation. The method comprises the steps that grouting is conducted on the inclined side of a bridge pier column to reinforce the soft soil foundation; a stress release hole is drilled in the side opposite to the inclined side of the bridge pier column; a lifting hole is drilled in an enlarged foundation on the inclined side of the bridge pier column; a lifting material is injected along the lifting hole to rectify the deviation of the bridge pier column; and the enlarged foundation of the bridge pier column is grouted and reinforced. According to the bridge pier column deviation rectifying method, before the lifting material is injected to rectify the deviation of the bridge pier column, the grouting is conducted to reinforce the soft soil foundation, so that the bearing capacity of the soft soil foundation is improved; the stress release holes are drilled in the opposite side of the inclined side of the bridge pier column, the deviation in the deviation rectifying direction is reduced, the deviation rectifying efficiency is improved, and therefore the reliability and accuracy of deviation rectifying of the bridge pier column are improved.

Description

technical field [0001] The present application relates to the field of building engineering construction, in particular to a method for correcting deviation of bridge pier columns used in soft soil foundations. Background technique [0002] Soft soil has the characteristics of high moisture content, large void ratio, high compressibility, high sensitivity, low strength, poor anti-disturbance, and poor permeability. Soft soil is used as the foundation of the structure, if it is not properly treated, it will easily cause uneven settlement of the building. The settlement and deformation of the soft soil foundation will cause damage to the foundation of the superstructure and its superstructure, and in severe cases, it will cause foundation exploration and even cause a structure toppling accident. [0003] In the prior art, when correcting the deviation of bridge pier columns, the building foundation is often reinforced and raised by grouting expansive polyurethane, and then ce...
