Open sea cofferdam and construction method of open sea cofferdam
The invention belongs to the technical field of constructional engineering, and particularly relates to an open sea cofferdam and a construction method of the open sea cofferdam. The open sea cofferdam comprises a gravel layer arranged on open sea rocks, and the gravel layer is higher than the open sea water level; a first block stone surface protection layer is arranged on the upstream side surface of the gravel layer; secant piles are arranged in the gravel layer, one ends of the secant piles extend into the open sea rocks, and the other ends of the secant piles are higher than the open sea water level. When the open sea cofferdam is constructed, shield construction does not need to be conducted on the upstream of flowing water and the periphery of the cofferdam, and the open sea rocks can be directly filled with gravels in a throwing mode, so that the gravel layer is rapidly formed; then the first block stone surface protection layer is constructed on the basis of the gravel layer. Therefore, by means of the open sea cofferdam structure, the construction period of the cofferdam can be effectively shortened, and then the construction cost can be reduced; meanwhile, the first block stone surface protection layer is arranged on the upstream side surface of the gravel layer, so that the damage of sea waves, typhoons and the like to the cofferdam can be effectively reduced.
本发明属于建筑工程技术领域，具体涉及一种外海围堰及外海围堰的施工方法。一种外海围堰，包括设置外海岩石上的碎石层，且碎石层高出外海水位；碎石层的迎水侧面上设置有第一块石护面层；碎石层内设置有咬合桩，且咬合桩的一端伸入外海岩石内、另一端高出外海水位。在对在本发明所提供的外海围堰施工时，无需在流水的上游以及在围堰的四周进行掩护施工，可以直接在外海岩石上抛填碎石，使碎石层快速成型；然后再在碎石层的基础上施工第一块石护面层。所以，通过本发明所提供的外海围堰结构能够有效地缩短围堰的施工工期，进而可以降低工程造价。同时，在碎石层的迎水侧面上设置第一块石护面层，能够有效减少海浪和台风等对围堰的损伤。
