Fan installation construction method based on portal type multi-pile fan foundation
The invention discloses a fan installation construction method based on a portal type multi-pile fan foundation. The method comprises the following steps: S1, sinking a plurality of steel pipe piles, and sinking the steel pipe piles to designed elevation positions by adopting a pile hammer; S2, hoisting and putting down a steel portal, and inserting the bottom ends of extending legs of the steel portal into the inner sides of the middle tops of the steel pipe piles in a one-to-one correspondence mode; S3, connecting and fixing a steel pipe pile flange and a steel portal extension leg flange, and performing grouting connection; S4, completing the overall installation of the fan on a steel portal bearing platform. According to the fan installation construction method based on the portal type multi-pile fan foundation, a large-capacity draught fan unit is installed on water in a deep sea area based on the portal type multi-pile fan foundation, construction is convenient, underwater piling and grouting are not needed, hoisting and transportation are convenient, the overall rigidity is large, stress is clear and stable, and when the installed capacity is large, the installation cost is low. Even if a small single pile diameter is used, the construction requirement can be met.
本发明公开了一种基于门架式多桩风机基础的风机安装施工方法，步骤如下：S1、沉入若干根钢管桩，采用打桩锤将钢管桩沉至设计标高位置；S2、起吊下放钢门架，使其钢门架外伸腿的底端分别各一一对应地插入至钢管桩中顶部内侧；S3、钢管桩法兰与钢门架外伸腿法兰连接固定并进行灌浆连接；S4、在钢门架承台上完成风机整体安装；该基于门架式多桩风机基础的风机安装施工方法基于门架式多桩风机基础实现在较深海域于水上安装大容量风机机组，施工方便，无需水下打桩、灌浆，不仅便于吊装、运输，且整体刚度大，受力明确、稳定，在大装机容量时，即使使用较小的单桩桩径，也可满足施工要求。
