Roadbed slope reinforcing structure, anchor cable fixing structure and construction method
The invention discloses a roadbed slope reinforcing structure, an anchor cable fixing structure and a construction method.The roadbed slope reinforcing structure comprises the anchor cable fixing structure, a plurality of sets of anchor cable holes (1) horizontally formed in an excavation roadbed (16), pre-stressed anchor cables (2) and anchoring ribs (3), the pre-stressed anchor cables (2) and the anchoring ribs (3) are anchored in the anchor cable holes (1), and the pre-stressed anchor cables (2) and the anchoring ribs (3) are bound and fixed; the pre-stressed anchor cable (2) comprises a first anchoring section located in an excavation roadbed (16), a second anchoring section located in a fill roadbed (15) and an extending section extending out of the fill roadbed (15), the second anchoring section is sleeved with a Pe sleeve (6) and placed in the fill roadbed (15), and the extending section of the pre-stressed anchor cable (2) is anchored to a concrete prefabricated check block (5) through an anchor cable fixing structure. Overflow holes (14) are formed in a pipe body of the Pe casing pipe (6), cement paste (4) is injected into the fill roadbed (15) through the Pe casing pipe (6) to consolidate the filler, the reinforcing effect is improved by combining the pre-stressed anchor cables and the prefabricated concrete block check block slope protection, meanwhile, the construction speed is increased, and the half-filling and half-excavation roadbed reinforcing construction technology is simplified.
本发明公开了路基边坡加固结构、锚索固定结构及施工方法，本加固结构包括锚索固定结构，以及水平设置于挖方路基(16)的多组锚索孔(1)，以及锚固于锚索孔(1)的预应力锚索(2)和锚固筋(3)，预应力锚索(2)和锚固筋(3)绑扎固定，预应力锚索(2)包括位于挖方路基(16)中的第一锚固段、位于填方路基(15)中的第二锚固段，以及从填方路基(15)伸出的伸出段，第二锚固段外套设有Pe套管(6)安放于填方路基(15)内，预应力锚索(2)的伸出段通过锚索固定结构与砼预制挡块(5)锚固，Pe套管(6)管身上布设溢流孔(14)，通过Pe套管(6)向填方路基(15)注入水泥浆(4)固结填料,通过采用预应力锚索和预制砼块挡块护坡两者结合来提高加固效果，同时提高施工速度，简化半填半挖路基加固施工工艺。
