The invention discloses an obstacle removing and pile pulling method of Larsen steel plate piles by a sleeve, and relates to the technical field of pulling of steel plate piles. The method comprises the following steps: 1, construction preparation is performed, and the construction site conditions and the engineering geological and hydrological geological conditions are investigated; 2, exploration survey is performed; 3, steel plate pile inspection is performed; 4, vibration hammer inspection is performed; 5, three supplies and one leveling are implemented; 6, the different proportion the expansion coefficient of the piles are researched; 7, the matching ratio of the piles is determined; 8, a deformation monitoring system is established; 9, an emergency scheme is established; 10, the ground change is monitored in real time; 11, impurities on pile heads of the Larsen steel plates are cleaned; 12, a matching pipe of a slewing drilling machine is used for removing an obstacle; 13, a pilecasing is buried; 14, the piles are pulled out; and 15, pile holes are backfilled. According to the obstacle removing and pile pulling method of the Larsen steel plate piles by the sleeve, old pilesare pulled out through the bottom stress mode, and according to the length of the old piles, corresponding models of the Larsen steel plate piles and mechanical vibrating hammers can be flexibly selected, surrounding soil bodies are separated, and the friction resistance is reduced; and due to the fact that the mode that the bottom is lifted and stressed, broken pile bodies can be pulled out for clearing.
本发明公开了一种拉森钢板桩套筒清障拔桩工法，涉及钢板桩的拔除技术领域，包括：进行施工准备其中对施工现场情况和工程地质、水文地质情况进行调查研究；进行勘探调查；进行钢板桩检查；进行振动锤检查；实施三通一平；研究桩的不同配比及其膨胀系数；确定桩的配合比；建立变形监测体系；制定应急方案；实时监测地面变化；清理拉森钢板桩桩头杂物；全回转钻机配套管清障；埋设护筒；拔桩；桩孔回填。该拉森钢板桩套筒清障拔桩工法，通过底部受力的方式进行旧桩拔除，根据旧桩桩长，可灵活选择相应型号的拉森钢板桩及机械振动锤，周围土体分离，减少摩阻力，由于使用底部托举受力的方式，因此对于断裂、破碎的桩体均能拔出清除。
