The invention discloses a structure and method for reinforcing a soft rock slope through rotary excavating anti-slide piles. The structure comprises the rotary excavating piles, reinforcement cage main reinforcements, reinforcement cage spiral reinforcements, reinforcing stirrups, a conversion bearing platform, bearing platform reinforcements, ground square piles, ground square pile main reinforcements, ground square pile stirrups, baffles, gravel soil, anchor cables, steel strands, guide caps, anchor sealing concrete and drainage holes. The rotary excavating piles are used for forming holes through large rotary excavating pile equipment, the rotary excavating piles and the ground square piles form an integral structure through a conversion bearing platform, and the rotary excavating piles are connected with a rock mass, gravelly soil and a baffle through anchor cables and form an organic whole with stress transmission of the ground square piles. The device can be applied to reinforcement of various soft rock slopes, the reliability of slope reinforcement can be well improved, necessary technical conditions can be provided for long-term stability of the slopes, and the problems that the efficiency is low, the manufacturing cost is high and the safety risk is large when the slopes are reinforced through manual hole digging anti-slide piles are solved.

本发明公开了一种旋挖抗滑桩加固软岩边坡的结构及加固方法，包括旋挖桩、钢筋笼主筋、钢筋笼螺旋筋、加强箍筋、转换承台、承台钢筋、地面方桩、地面方桩主筋、地面方桩箍筋、挡板、碎石土、锚索、钢绞线、导向帽、封锚砼和泄水孔；所述旋挖桩采用大型旋挖桩设备成孔，旋挖桩通过转换承台与地面方桩形成一个整体结构，旋挖桩通过锚索连接岩体、碎石土、挡板，并与地面方桩的受力传递形成一个有机的整体；本发明可在各种软岩边坡加固中应用，能够很好的提高边坡加固的可靠性，可为边坡长期的稳定性提供必要的技术条件，解决人工挖孔抗滑桩加固边坡的效率低、造价高、安全风险大的难题。
