Construction method for widening shed tunnel of roadbed of existing high and steep slope
The invention relates to the technical field of engineering construction, in particular to a construction method for widening a shed tunnel of a roadbed of an existing high and steep slope, which comprises the following steps: S01, removing broken stones and loose dangerous stones on a hillside, and performing spray protection on a mountain body of an excavation surface; s02, an outer side wall and a concrete protection arch of the shed tunnel are constructed; s03, a slope filling rock layer and a clay water-resisting layer are laid on the concrete protection arch; s04, excavating the slope soil body of the expanding and excavating part step by step in sequence to form a widened shed tunnel, and constructing support measures on the slope soil body of the expanding and excavating part in time; s05, a new roadbed, a waterproof plate, other drainage facilities, an inverted arch, an arch wall and a bottom plate are laid in the widened shed tunnel; s06, construction of a ditch, a cable trench, a road surface and other accessory structures in the widened shed tunnel is conducted; according to the method, the excavated earth volume can be reduced, the engineering cost is lower, potential safety hazards caused by high slope slump, rockfall and the like can be eliminated, the natural environment is protected, and the safety, progress and quality of engineering are guaranteed.
本发明涉及工程施工技术领域，具体为一种对既有高陡边坡的路基扩宽棚洞施工方法，S01、清除山坡上的碎石及松动的危石，并对开挖面山体进行喷防护；S02、施做棚洞外侧边墙和混凝土护拱；S03、在混凝土护拱上铺设坡度填土石层和粘土隔水层；S04、依次分步开挖扩挖部边坡土体，形成扩宽棚洞，并及时在扩挖部边坡土体上施工支护措施；S05、在扩宽棚洞内铺设新路基、防水板、其它排水设施、仰拱、拱墙和底板；S06、进行扩宽棚洞内水沟、电缆沟、路面等附属结构施工；本发明既能减少开挖土方量，工程造价更低，还能消除高边坡滑坍、落石等造成的安全隐患，保护自然环境，保证工程的安全、进度和质量。
