The invention discloses a device and method for reducing deviation of a reinforcement cage of a slurry retaining wall cast-in-situ bored pile, and belongs to the technical field of pile foundation engineering construction. The device comprises a soil body and a reinforcement cage in a hole opening, a prefabricated concrete foundation cross fender pile and a steel pile casing are arranged in the soil body, bentonite slurry, a reinforcement cage fixing device and a positioning device are arranged in the hole opening, and the center position of a designed pile position is determined through the prefabricated concrete cross fender pile in the soil body in early-stage measurement; the reinforcement cage is temporarily fixed through the reinforcement cage fixing device, and then the final position of the reinforcement cage is adjusted by comparing the reinforcement cage positioning device with the center point of the cross-shaped fender pile in the soil body. The method is high in construction precision, economical, reasonable, safe and reliable, and the quality is guaranteed.
本发明公开了一种降低泥浆护壁钻孔灌注桩钢筋笼偏位的装置及方法，属于桩基工程施工技术领域。本发明包括土体、孔口内钢筋笼，土体内设有预制混凝土基础十字护桩、钢护筒，孔口内设有膨润土泥浆、钢筋笼固定装置和定位装置，前期测量通过土体内的预制混凝土十字护桩确定设计桩位中心位置，在下放钢筋笼后，使用钢筋笼固定装置将钢筋笼进行临时固定，然后通过钢筋笼定位装置与土体内的十字护桩中心点进行比对来调整钢筋笼的最终位置。本发明施工精度高、经济合理、安全可靠、质量有保证。
