Construction method for shield rapid receiving under suspended wall support
The invention discloses a construction method for shield rapid receiving under suspended wall support, which is characterized in that shield receiving is directly carried out after a shield shaft bottom plate is completed, so that an interval is ensured to be communicated in advance, the waiting time of shield shutdown is shortened, the cost during shutdown is reduced, and favorable conditions are provided for follow-up interval accessory projects; during construction of a shield well main body structure, a tunnel portal steel ring does not need to be pre-buried, and the cost is reduced; when a middle plate and a top plate of a shield well are constructed, shield hoisting holes do not need to be reserved, later hole blocking is avoided, structural construction organization is greatly facilitated, the work efficiency is improved, and the cost is reduced; top plate waterproofing can be completed at one time, and top plate waterproofing quality is improved.
本发明公开了一种吊脚墙支护下的盾构快速接收的施工方法，本发明通过在完成盾构井底板后直接进行盾构接收，确保了区间提前洞通，减少了盾构停机等待的时间，降低了停机期间的成本，为后续区间附属工程提供有利条件；在盾构井主体结构施工时，无需预埋洞门钢环，降低成本；在盾构井中板及顶板施工时，无需预留盾构吊装孔，避免后期的孔洞封堵，极大方便了结构施工组织，提高工效，降低成本；顶板防水可一次性完成，提高顶板防水质量。
