Rock slope arch anchor pile composite supporting structure and supporting method
The invention relates to the field of slope supporting, and discloses an arch-anchor-pile composite supporting structure which is reasonable in structural design, low in cost and capable of effectively controlling engineering disasters of rock slopes which are ultrahigh, deep and steep by 40 m and large in thrust. And after the arched beam is finished, the anchor cable is locked by the anchor head after prestress is applied to the anchor cable. The arched girders and the surrounding piles can be used as inter-pile interval protection and can also be used as anchor cable supporting points, the construction cost is reduced, meanwhile, force passing through the arched girders is transmitted to the supporting piles and the triangular supporting plates, the section size and the anchoring depth of a traditional pile-anchor supporting structure of the ultrahigh and steep rock slope are reduced, the purpose of reducing the excavation width of a foundation pit is achieved, and the construction efficiency is improved. And the construction risk is reduced.
本发明涉及边坡支护领域，公开了一种结构设计合理、成本低、且能够有效控制超高40m深、陡的且推力巨大的岩质边坡工程灾害的拱锚桩复合支护结构，相较于传统桩锚支护结构而言，拱梁不占用基坑内部空间，拱梁完成后只需将锚索施加预应力后用锚头锁定锚索。本发明中的拱梁和围桩即可作为桩间间隔防护，也可作为锚索支撑点，降低了施工成本，同时通过拱梁的力传递到支撑桩和三角形支撑板上，减小超高、陡的岩质边坡传统桩锚支护结构截面尺寸和锚固深度，达到了减小基坑开挖宽度的目的，降低了施工风险，适合推广使用。
