Steep mountain embedded road construction method
The invention belongs to the technical field of capital construction, and particularly discloses a steep mountain embedded road construction method. The steep mountain embedded road construction method comprises the following steps that surveying and setting out are achieved, and a road mileage point coordinate and a road center point elevation are set out by using a GPS according to an original coordinate control point; construction is started from an upper sideline, excavation is conducted step by step from top to bottom, excavation is conducted step by step, reinforcement is conducted step by step, and an embedded road with a full-excavation roadbed is formed; upper slope renovation is conducted, specifically, broken suspended convex dangerous rock and broken blocks are cleared and renovated, and a local abrupt slope section is subjected to square cutting and strong weathering layer excavation; a ditch is dug, the states of a foundation trench and a side slope are checked, and earth excavation is carried out from top to bottom in a layered and segmented manner sequentially; an upper side slope is greened, broken stones and unconsolidated strata on a rock surface are cleaned to flatten a slope surface, and spray-seeding construction is performed. According to the steep mountain embedded road construction method, by adopting the form of fully excavating the roadbed, the full-section strength of the roadbed is obviously improved, and the transportation safety of large pieces is fundamentally guaranteed.
本发明属于基建技术领域，具体公开一种陡峭山地嵌入式道路施工方法。一种陡峭山地嵌入式道路施工方法包括以下步骤：测量放线，根据坐标原始控制点，用GPS放出道路里程点坐标以及道路中心点高程；从上边线开始施工，按照从上至下的顺序逐级开挖，逐级开挖逐级加固，形成全挖方路基的嵌入式道路；上边坡整修，对破碎后的悬凸危岩、破裂块体进行清除整修，对局部陡坡段进行削方及强风化层挖除；挖掘水沟，检查基槽和边坡状态从上到下分层分段依次进行土方开挖；上边坡绿化，清理岩面碎石和松散层，使坡面平整，并进行喷播施工。通过采用全挖方路基的形式，显著提升了路基全断面强度，大件运输安全得到根本保证。
