Underground corridor differential settlement repairing structure and repairing method thereof
The invention relates to an underground corridor differential settlement repairing structure. The underground corridor differential settlement repairing structure comprises an underground corridor and steel pipe piles, wherein two rows of through holes are formed in the bottom of the underground corridor; the hole diameter of the through holes is larger than the pile diameter of the steel pipe piles; the steel pipe piles are sequentially driven into the through holes in a static pressure manner; each steel pipe pile is filled with C25 concrete; every two vertically-adjacent steel pipe piles are welded together till the steel pipe piles enter a low-compressibility soil layer or rock layer, and C40 micro-expansion early-strength concrete is adopted for pile sealing; and static pressure anchor rod piles are driven into the bottom of the underground corridor where differential settlement is generated, the underground corridor is prevented from further sinking, the sinking part can be properly lifted upwards, and very good popularization prospects are achieved.
本发明涉及一种地下连廊不均匀沉降的修复结构，包括地下连廊和钢管桩，所述地下连廊底部开有两排通孔，通孔的孔径大于钢管桩的桩径，钢管桩采用静压方式依次打入通孔内，每节钢管桩内填充C25混凝土，上下相邻的两节钢管桩焊接在一起，直至钢管桩进入低压缩性土层或岩层，采用C40微膨胀早强混凝土封桩；在已产生不均匀沉降的地下连廊底部打入静压锚杆桩，阻止其进一步下沉，已下沉部分还能适当往上抬，具有很好的推广前景。
