Segmental precast and sinking technology for underwater construction
The invention discloses a segmental precast and sinking method for underwater construction. The method comprises steps as follows: a step of segmental precast: precast of reinforcing steel bars, rolled steel and/or concrete is performed in a precast site, and precast segments (1) of the reinforcing steel bars, the rolled steel and/or the concrete are obtained; a step of pipe joint formation: two or more precast segments (1) are subjected to assembling butt joint and tensioning treatment on a semi-submerged ship (2), and single pipe joints are obtained; and a step of pipe joint sinking and buttjoint: the semi-submerged ship (2) is transported to the sinking position of water surface in a floating manner and then dives, multiple single pipe joints are sunken and subjected to underwater buttjoint, and an underwater structural system is formed. According to the scheme, the problem of large construction difficulty of underwater pipe sinking can be solved, and the effect of reducing the construction difficulty of underwater pipe sinking is realized.
本发明公开了一种用于水下施工的节段预制及沉放方法，包括：节段预制步骤：在预制场地进行钢筋、钢材和/或混凝土的预制，得到钢筋、钢材和/或混凝土的预制节段(1)；管节形成步骤：在半潜船(2)上，对两段以上的预制节段(1)进行拼装对接和张拉处理，得到单个管节；管节沉放及对接步骤：将半潜船(2)浮运至沉放位置水面后下潜，沉放多个单个管节，并对多个单个管节进行水下对接，形成水下结构体系。本发明的方案，可以解决水下沉管的施工难度大的问题，达到降低水下沉管的施工难度的效果。
