Construction method of deepwater bare rock cofferdam
The invention relates to a construction method of a deepwater bare rock cofferdam, and belongs to the technical field of cofferdam construction.The construction method of the deepwater bare rock cofferdam comprises the following steps that a ring beam is assembled on a steel casing; a hanging system is installed at the top end of the steel casing, and a ring beam is lowered to a preset position through a finish rolling twisted steel bar system in the hanging system; the ring beam is supported on a rock stratum through a plurality of supporting pieces; and inserting and driving the lock catch steel pipe piles by taking the ring beam as guide. According to the construction method, the suspended ring beam is directly supported on the rock stratum ingeniously through the supporting pieces, the safety coefficient of the construction process is increased, the construction method has the advantages of being low in construction cost, simple, rapid and convenient to operate, high in practicability and the like, and the construction efficiency can be improved; meanwhile, in the process of inserting and driving the lock catch steel pipe pile, if the finish rolling deformed steel bar is broken due to shearing, the ring beam can transmit the dead weight to a rock stratum through the supporting piece, and safety accidents are avoided.
本申请涉及一种深水裸岩围堰的施工方法，属于围堰施工技术领域，该深水裸岩围堰的施工方法包括以下步骤：在钢护筒上拼装圈梁；在钢护筒的顶端安装吊挂系统，利用吊挂系统中的精轧螺纹钢筋系统将圈梁下放到预设位置；利用多个支撑件将圈梁支撑在岩层上；以圈梁为导向插打锁扣钢管桩。本申请的施工方法巧妙的利用支撑件将悬挂的圈梁直接支撑在岩层上，增加了施工过程的安全系数，具有施工成本低、施工方法简单、操作快捷方便、实用性强等优点，能够提高施工效率；同时，在插打锁扣钢管桩的过程中，若精轧螺纹钢因受剪而断裂，圈梁可以将自重通过支撑件传递到岩层上，避免安全事故的发生。
