Construction method for ecologically treating tunnel entrance and exit structure through foam concrete
The invention relates to a construction method for ecologically treating a tunnel entrance and exit structure through foam concrete. The construction method comprises the steps that (1), micro steel pipe piles are constructed; (2), a clip-shaped hoop is pre-embedded; (3), a prefabricated baffle foundation is constructed; (4), the first prefabricated baffle is installed; (5), a prefabricated baffle cast-in-place section is constructed; (6), a top prefabricated baffle is installed; (7), cast-in-place concrete support construction is carried out; (8), a drainage system is constructed; (9), the two sides are backfilled; (10), foam concrete backfilling is carried out; and (11) construction of soil dressing and greening is carried out. The construction method has the beneficial effects that the micro steel pipe piles are arranged at the bottoms of the slide-resistant piles, so that the slide-resistant bearing capacity is further improved; pre-embedded angle steel is arranged at the bottom of the prefabricated slab, and prefabricated slab installation precision and construction efficiency are improved; anchoring structures are arranged on the two sides of the prefabricated slab system, and the overall stability of the anti-sliding system can be improved; and a reinforcing mesh and drainage systems are arranged in the foam concrete, and drainage systems are arranged on the two sides of the concrete support, so that the drainage effect is guaranteed during construction.
本发明涉及泡沫混凝土生态处治隧道进出口结构的施工方法，包括步骤：1)微型钢管桩施工；2)预埋回形箍；3)预制挡板基础施工；4)首块预制挡板安装；5)预制挡板现浇段施工；6)顶部预制挡板安装；7)现浇混凝土支护施工；8)排水体系施工；9)两侧回填；10)泡沫混凝土回填；11)施工客土、绿化。本发明的有益效果是：抗滑桩底部设置微型钢管桩，进一步提高抗滑承载力；预制板底部设置预埋角钢，提高预制板安装精度及施工效率；预制板体系作用两侧设置锚固结构，可提高抗滑体系整体稳定性；泡沫混凝土内设置钢筋网及排水体系，混凝土支护两侧设置排水体系，使得施工时排水效果得以保证。
