In-situ repair device and method for deformation of steel sheet pile enclosure structure
The invention discloses a steel sheet pile enclosure structure deformation in-situ repairing device and method, and belongs to the technical field of underground engineering construction. Comprising an anchoring counter-force unit and a hydraulic pushing unit, and the anchoring counter-force unit is laid on the deformed steel sheet pile and anchored into a stratum soil body so as to generate counter-force on the deformed steel sheet pile and the stratum soil body; and the hydraulic pushing unit is horizontally arranged between the oppositely arranged anchoring counter-force units so as to be matched with the anchoring counter-force units to push the deformed steel sheet pile, and in-situ repair is achieved. On the premise that the construction cost and the environment disturbance are controllable, in-situ rapid repairing can be conducted on the deformed position, and the supporting toughness of the steel sheet pile enclosure structure is improved; the problems that a steel sheet pile deformation recovery process is high in cost and low in efficiency, and sedimentation deformation of surrounding strata can be intensified are solved.
本发明公开了一种钢板桩围护结构变形原位修复装置及方法，属于地下工程施工技术领域。包括锚定反力单元和液压顶推单元，锚定反力单元铺设于变形钢板桩上并锚入地层土体，以对变形钢板桩及地层土体产生反力；液压顶推单元水平设置于相对设置的锚定反力单元之间，以与锚定反力单元配合对变形钢板桩进行顶推，实现原位修复。能够在施工成本和环境扰动可控的前提下对变形位置处进行原位快速修复，提升钢板桩围护结构的支护韧性；解决了钢板桩变形恢复工艺成本高、效率低下且会加剧周边地层沉降变形的问题。
