Reinforcing and deviation rectifying construction method for mixed coal bunker
The invention discloses a mixed coal bunker reinforcing and deviation rectifying construction method which is specifically implemented according to the following steps that 1, according to design requirements, an operation pit is excavated in the position, to be subjected to static pressure pile underpinning, of a mixed coal bunker composite foundation; 2, a steel pipe concrete pile is adopted in the composite foundation for static pressure pile underpinning, static pressure pile underpinning is conducted on the side with large settlement, forced landing deviation rectifying work is conducted on the side with small settlement after reinforcement and settlement stopping of the side with the large settlement amount are completed, and static pressure pile underpinning work is conducted on the side with small settlement after forced landing deviation rectifying is completed; and 3, after underpinning of all the static pressure piles is finished, the operation pit is backfilled, and reinforcing and sinking stopping work is finished. According to the deviation rectifying method, the problem that the deviation rectifying effect is poor due to the fact that the deviation rectifying amount is difficult to accurately control in an existing deviation rectifying method is solved.
本发明公开了混煤仓加固纠偏工法，具体按照以下步骤实施：步骤1，按照设计要求，在混煤仓复合地基的待进行静压桩托换位置开挖操作坑；步骤2，在复合地基内采用钢管混凝土桩进行静压桩托换，先对沉降较大一侧进行静压桩托换，沉降量大一侧加固止沉结束后对沉降较小的一侧进行迫降纠偏工作，沉降较小一侧迫降纠偏结束后进行静压桩托换工作；步骤3，在所有静压桩托换结束后，回填操作坑，加固止沉工作结束。本发明纠偏工法解决了现有纠偏方法存在较难精确控制纠偏量，导致纠偏效果不佳的问题。
