According to the underwater prefabricated part mounting method, a pull ring is pre-embedded in the underwater base surface, and hanging rings are pre-embedded in the front and rear parts of the top surface of a prefabricated part; one end of a traction rope is connected to a hanging ring on the front portion of the first prefabricated part, the other end of the traction rope penetrates through a pull ring, the first prefabricated part is hung to the position close to the target position, the traction rope is pulled to drive the first prefabricated part to be close to the target position, the first prefabricated part descends to the underwater base surface, and if the traction rope cannot pull the first prefabricated part, the first prefabricated part is in place; one end of a traction rope is connected to the front hanging ring of the current prefabricated part, the other end of the traction rope penetrates through the rear hanging ring of the previous prefabricated part, the current prefabricated part is hoisted to the position above the position nearby the previous prefabricated part, the traction rope is pulled to drive the current prefabricated part to be close to the previous prefabricated part, and the current prefabricated part descends to the underwater base surface; and if the traction rope cannot pull, the current prefabricated part is butted in place. According to the invention, one-time accurate positioning and mounting of the prefabricated part can be realized.
本发明公开了一种水下预制构件安装方法,水下基底面上预埋设置拉环,预制构件顶面前后部预埋设置吊环;在第一个预制构件前部吊环上连接牵引绳一端,牵引绳另一端穿过拉环,将第一个预制构件吊至目标位置附近上方,拉动牵引绳带动第一个预制构件靠近目标位置,第一个预制构件降至水下基底面,牵引绳无法拉动则第一个预制构件到位;在当前预制构件前部吊环上连接牵引绳一端,牵引绳另一端穿过上一个预制构件后部吊环,将当前预制构件吊至上一个预制构件附近上方,拉动牵引绳带动当前预制构件靠近上一个预制构件,当前预制构件降至水下基底面,牵引绳无法拉动则当前预制构件对接到位。本发明能够实现预制构件的一次性精确定位安装。
