Construction method for large-diameter double-row pile retaining of deep foundation pit near subway
The invention discloses a construction method for a large-diameter double-row pile support for a deep foundation pit near a subway. The construction method mainly comprises the steps that excavation and sloping are conducted from a surface soil body, and a drainage ditch is built; forming holes in the foundation piles to form two rows of pile holes; two rows of prefabricated reinforced concrete piles are implanted into the pile holes to form double-row piles; top beam and coupling beam foundation trenches are excavated, and prefabricated reinforced concrete top beams and prefabricated reinforced concrete coupling beams are implanted; concrete is poured into joints among the prefabricated reinforced concrete top beams, the prefabricated reinforced concrete coupling beams and the double-row piles for wet connection; excavating the foundation pit to the bottom of the deep foundation pit, hanging a reinforcing mesh between piles, spraying concrete and the like. The technical problems of environmental pollution and subway disturbance caused in the construction process in the prior art are solved.
本发明公开了一种用于临地铁深基坑大直径双排桩支挡的施工方法，主要包括：从表层土体开挖、放坡，建造排水沟；基桩成孔，形成两排桩孔；在桩孔中植入两排预制钢筋混凝土桩形成双排桩；开挖冠梁、连梁基槽，植入预制钢筋混凝土冠梁和预制钢筋混凝土连梁；在预制钢筋混凝土冠梁和预制钢筋混凝土连梁及双排桩之间的接头浇注混凝土进行湿接；基坑开挖，挖至深基坑底部，桩间挂钢筋网，喷射混凝土等步骤。本发明解决了现有技术在施工过程中造成的环境污染和对地铁扰动的技术问题。
