Tunnel anchor construction method
The tunnel anchor construction method comprises the steps that a construction shortcut is formed in a side slope of a gentle slope mountain, and a construction transverse hole is formed in a steep mountain from the construction shortcut to a target position; a first anchor hole and a second anchor hole which are arranged in parallel are formed in the target position towards the inner side of the mountain, and the first anchor hole and the second anchor hole are transversely communicated through the construction transverse hole; a first cable hole and a second cable hole which are arranged in parallel are formed in the target position towards the outer side of the mountain, and the first cable hole and the second cable hole are transversely communicated through the construction transverse hole; and anchor plug bodies are poured in the first anchor hole and the second anchor hole correspondingly, cable saddles are poured on the sides, close to the outer side of the mountain, of the anchor plug bodies, and main cables are erected. According to the construction method, the construction shortcut is formed in the gentle slope through excavation, the transverse hole is constructed on the abrupt slope, and the anchor hole and the cable hole are excavated from the target position where the transverse hole is constructed to the two sides, so that excavation and slope protection operation on the abrupt slope can be avoided, the construction difficulty can be reduced, the construction safety can be improved, and damage to the natural slope surface of the mountain can be reduced.
本申请公开的隧道锚施工方法，包括：在缓坡山体的边坡上开设施工便道，从施工便道向陡峻山体内开设施工横洞至目标位置；在目标位置向山体内侧开设并列布置的第一锚洞和第二锚洞，且施工横洞横向连通第一锚洞和第二锚洞；在目标位置向山体外侧开设并列布置的第一缆洞和第二缆洞，施工横洞横向连通第一缆洞和第二缆洞；分别在第一锚洞和第二锚洞中浇筑锚塞体，在锚塞体靠近山体外侧的一侧浇筑索鞍，并架设主缆。该施工方法通过开挖在缓坡上开设施工便道、在陡坡上开始施工横洞，从施工横洞所在目标位置向两侧分别开挖锚洞及缆洞，可避免在陡峻边坡上进行开挖和护坡作业，从而可降低施工难度，提高施工安全，并可减小对山体自然坡面的破坏。
