Open caisson method rotational flow shaft wall structure and construction method
The invention discloses an open caisson method rotational flow shaft wall structure and a construction method.The open caisson method rotational flow shaft wall structure comprises a tip cylinder wall and an upper cylinder wall arranged above the tip cylinder wall, protective layers are arranged on the outer side of the tip cylinder wall and the outer side of the upper cylinder wall, and a blade foot steel protective plate is arranged at the blade foot of the tip cylinder wall; the thickness of the tip cylinder wall outer protection layer is larger than that of the upper cylinder wall protection layer. Compared with the prior art, the open caisson method has the beneficial effects that compared with a conventional open caisson method, the friction force between the upper cylinder wall and the soil body is reduced, the open caisson speed is increased, and the construction period is advanced; compared with a conventional open caisson method, other sinking assisting methods do not need to be adopted, and the measure cost is saved; the strength and rigidity of the tip cylinder wall are enhanced, smooth soil cutting is facilitated, and structural stress is reasonable.
本发明公开了一种沉井法旋流井筒壁结构及施工方法，沉井法旋流井筒壁结构，包括尖端筒壁，以及设置在尖端筒壁上方的上部筒壁，尖端筒壁和上部筒壁外侧均设置有保护层，尖端筒壁的刃脚处设置有刃脚钢护板，尖端筒壁外保护层的厚度大于上部筒壁的保护层厚度。与现有技术相比，本发明的有益效果在于：相比常规沉井法，减少上部筒壁与土体之间摩擦力，沉井速度加快，工期提前；相比常规沉井法，无需采取其它助沉方法，节约措施费用；尖端筒壁强度和刚度加强，利于顺利切土且结构受力合理。
