Sludge geological bridge foundation anti-shear composite foundation treatment construction method
The invention discloses a sludge geological bridge foundation shear-resistant composite foundation treatment construction method which comprises the following steps: firstly, constructing a plurality of supporting piles at corresponding positions of a foundation according to a design drawing; steel sheet piles or lock catch steel pipe piles are inserted and driven, and a cofferdam is formed outside the range of the supporting piles; then, stirring piles are constructed in the cofferdam through a drilling machine, and the spaces among the supporting piles are filled with the stirring piles; when a circle of stirring piles around the supporting pile are constructed, the distance between the outer side of a drill rod of a drilling machine and the outer wall of the supporting pile is 20-30 cm, and along with drilling of the drill rod of the drilling machine, cement paste is sprayed to a soil body between the drill rod of the drilling machine and the supporting pile through a flushing pipe; the cement paste sprayed out of the flushing pipe impacts and collapses a soil body between a drill rod of the drilling machine and the supporting pile to the mixing pile, the collapsed soil body and the cement paste of the mixing pile are mixed to form new cement paste, and the space after the soil body collapses is filled with the new cement paste. The structure has the effect of improving the shearing resistance of the supporting piles and the bearing platform.
本发明公开了一种淤泥地质桥梁基础抗剪复合地基处理施工方法，先按照设计图纸，在地基的对应位置施工多根支撑桩；并插打钢板桩或者锁扣钢管桩，在支撑桩范围外形成围堰；之后使用钻机在围堰内施工搅拌桩，搅拌桩将各支撑桩之间的空间填满；施工支撑桩周围一圈的搅拌桩时，钻机的钻杆的外侧与支撑桩的外壁之间的距离为20‑30cm，随着钻机的钻杆的钻进，使用冲洗管对钻机的钻杆和支撑桩之间的土体喷射水泥浆，冲洗管喷射出的水泥浆将钻机的钻杆和支撑桩之间的土体冲击塌落至搅拌桩处，塌落的土体与搅拌桩的水泥浆混合形成新的水泥浆并填充土体塌落后的空间。本申请具有提高支撑桩和承台的抗剪力的效果。
