Rotational flow shaft wall open caisson and reverse construction integrated construction method
The invention discloses a rotational flow well shaft wall open caisson and reverse construction integrated construction method, and relates to the technical field of rotational flow well construction. Compared with a conventional open caisson method, a cylinder wall blade foot does not need to sink below a bottom plate, and a reinforced concrete cylinder wall in a cone area is saved; the cone part earthwork does not need to be excavated, earthwork excavation volume is reduced, and construction period is shortened; conical concrete filling is not needed, a large amount of concrete is saved, and cost is remarkably saved. Compared with a reverse construction method, no support pile exists around, only the joist is arranged, the joist acts as a crown beam, the compression area is increased, the cylinder wall is prevented from sinking, and the cylinder wall is stabilized. The joist is additionally arranged on the outer side above the cylinder wall, friction force with the cylinder wall and supporting force of the blade feet jointly support and restrain sinking of the rotational flow shaft wall from the upper, middle and lower space of the structure, and the effect is remarkable. The closed-loop groove belt is added, the roughness of the contact face of the construction joint is effectively increased, a water seepage channel is blocked, and the closed-loop groove belt and the rubber water stop strip form a double-waterproof system.
本发明公开了一种旋流井筒壁沉井与逆作集成的施工方法，涉及旋流井施工技术领域。本发明相比常规沉井法，无需筒壁刃脚下沉到底板以下，节约锥体区域钢筋混凝土筒壁；锥体部分土方无需开挖，减少土方开挖量，缩短工期；无需进行锥体混凝土填充，节省大量混凝土，节约成本显著。相比逆作法，周围无支护桩，只有托梁，而托梁作用相当于冠梁，增加了受压面积，阻止了筒壁下沉，稳固了筒壁。筒壁上方外侧增加托梁，与筒壁摩擦力、刃脚支撑力共同从结构上中下空间上支撑抑制旋流井筒壁下沉，效果显著。增加闭环的凹槽带，有效增加了施工缝接触面粗糙度，渗水渠道得到阻止阻断，与橡胶止水条形成双重防水体系。
