Construction technology of underground comprehensive pipe gallery
The invention discloses a construction technology of an underground comprehensive pipe gallery. The construction technology comprises the following processes of foundation pit excavation, pipe gallery main body construction and road surface construction. The foundation pit excavation process comprises the following steps of pit bottom reinforcement, foundation pit supporting, foundation pit dewatering and foundation pit excavation. In the pit bottom reinforcement step, a cement mixing pile and a PHC pipe pile are adopted to reinforce the pit bottom. In the foundation pit supporting step, steel sheet piles, steel enclosing purlins and horizontal supports are adopted for supporting. The pipe gallery main body construction process comprises the following steps of cushion layer construction, bottom plate steel bar binding, bottom plate formwork erecting, bottom plate concrete pouring, side wall and top plate steel bar binding, side wall and top plate formwork erecting, side wall and top plate concrete pouring, formwork removal concrete curing, waterproof engineering and foundation pit backfilling. The road surface construction process comprises the following steps of gravel hardcore construction, cement stable layer construction and asphalt surface layer construction. The construction technology of the underground comprehensive pipe gallery has the advantages of being good in construction quality, capable of saving time and labor, capable of reducing construction cost and good in waterproof effect.
本发明公开了一种地下综合管廊的施工工艺，包括以下流程：基坑开挖、管廊主体施工和路面施工；基坑开挖流程包括以下步骤：坑底加固、基坑支护、基坑降水和开挖基坑；进行坑底加固步骤时，采用水泥搅拌桩和PHC管桩对坑底进行加固；进行基坑支护步骤时，采用钢板桩、钢围檩和水平支撑支护。管廊主体施工流程包括以下步骤：垫层施工、底板钢筋绑扎、底板模板支立、底板砼浇筑、侧墙和顶板钢筋绑扎、侧墙和顶板模板支立、侧墙和顶板砼浇筑、拆模砼养护、防水工程和基坑回填。路面施工流程包括以下步骤：碎石垫层施工、水稳层施工和沥青面层施工。本发明地下综合管廊的施工工艺，具有施工质量好、省时省力，降低施工成本，且防水效果好的特点。
