High slope mountain shed tunnel construction method
The invention relates to the technical field of engineering construction, in particular to a high slope mountain shed tunnel construction method which comprises the steps that S01, the top of a shed tunnel is excavated, and an excavated slope is supported; s02, a right soil body of the shed tunnel is excavated, and a right temporary support is carried out; s03, a left soil body of the shed tunnel is excavated, and left primary supporting, advance anchor rod supporting and first temporary steel frame supporting are conducted; s04, a left shed tunnel structure and a bottom plate structure are poured; s05, constructing a temporary steel frame support II, and removing the existing temporary steel frame support I; s06, constructing a right shed tunnel structure; s07, auxiliary structures such as ditches, cable trenches and pavements in the shed tunnel are constructed; s08, backfilling and back pressing the top of the shed tunnel, and constructing a top impermeable layer, a drainage ditch and greening; the excavation amount can be reduced, damage to the natural environment of the mountain body is reduced as much as possible, deformation and instability of the side slope caused by long-time exposure are avoided, and it is guaranteed that engineering is safely and smoothly carried out; and the damage to the shed tunnel structure caused by water accumulation and non-dense backfilling can be avoided.
本发明涉及工程施工技术领域，具体为一种高边坡榜山棚洞施工方法，S01、棚洞顶部开挖，对开挖后的边坡进行边坡支护；S02、棚洞右幅土体开挖，并进行右幅临时支护；S03、棚洞左幅土体开挖，进行左幅初期支护、超前锚杆支护，临时钢架支护一；S04、浇筑左幅棚洞结构、底板结构；S05、施工临时钢架支护二，并拆除既有临时钢架支护一；S06、施工右幅棚洞结构；S07、对棚洞内水沟、电缆沟、路面等附属结构进行施工；S08、棚洞顶部回填反压、顶部防渗层、排水沟、绿化施工；本发明能减少开挖量，尽量降低对山体自然环境的破环，避免因长时间暴露造成边坡的变形和失稳，保证了工程的安全顺利进行；还能避免因积水和回填不密实，造成的棚洞结构破坏。
