Rock high slope pile plate type retaining wall pre-stressed anchor cable supporting structure and method
According to the pile plate type retaining wall pre-stressed anchor cable supporting structure and method for the high rock slope, under the condition that the high rock slope is supported by the anti-slide piles, the drilling technology of the broken surrounding rock section and the in-hole wall protection technology are adopted, the flexible anchor cables and the rigid anti-slide piles are stressed in a coordinated mode, and the anti-slide pile supporting effect is achieved; according to the anti-slide pile, disturbance to surrounding soil can be effectively reduced, the compactness and compressive strength of mortar are guaranteed, the bonding strength between the anti-slide pile and the soil and the anchor cable is improved, and the resistance of the anti-slide pile to the surrounding soil when the surrounding soil changes is improved; in addition, the problems of early-stage relaxation and deformation after tensioning retraction and stress of the anchor cable are solved by using an over-tensioning and compensation tensioning process; the problem of supporting integrity is solved by using a full-hole one-time grouting process; the construction quality is improved while the construction safety is guaranteed, meanwhile, the influence on the surrounding environment is small, environmental protection is facilitated, and high social benefits are achieved.
本发明所述的一种岩质高边坡桩板式挡墙预应力锚索支护结构及方法，岩质高边坡在使用抗滑桩支护的情况下，采用破碎围岩段的钻进工艺和孔内护壁技术，让柔性的锚索与刚性的抗滑桩协调受力，不仅可以更有效的减少对周围土体的扰动，保证了砂浆自身的密实度和抗压强度、增大了与土体和锚索之间的粘结强度、增加了抗滑桩对周围土体发生变化时的抵抗力，另外用超张拉和补偿张拉工艺解决锚索张拉回缩、受力后的前期松弛变形难题；用全孔一次注浆工艺解决支护整体性问题；在保证施工安全的同时，提升施工质量，同时对周围环境影响小，有利于环境保护，具有较高的社会效益。
