Method for reinforcing and heightening round structure pool through prestressed concrete technology
The invention discloses a method for reinforcing and heightening a round structure pool by a prestressed concrete technology. The method comprises the following steps that a plurality of prestressed ring beams are set around the outer side of an original pool wall of a pool, a plurality of anchoring ribs extending along the vertical direction on the outer side of the original pool wall of the pool are set, a prestressed tendon is set in each prestressed ring beam, and a plurality of anchoring ribs are set in each prestressed ring beam; tail ends of the prestressed tendons penetrate through the anchoring ribs; the prestressed tendons are tensioned, the tail ends of the prestressed tendons are anchored to the anchoring ribs, and the exposed parts of the prestressed tendons are subjected to anti-corrosion sealing treatment; heightening component construction is conducted, and heightening components comprise pool walls, walkway plates, center cylinders, water outlet wells and mud outlet wells, and the original positions of the water outlet wells are heightened. According to the method for the circular pool, the stress condition of the circular pool is remarkably improved through small engineering amount, so the bearing capacity of the circular pool is improved, the effects of reinforcing and processing capacity improvement of the pool are achieved, and the reinforcing and heightening transformation method for the circular pool is simple and reliable in structure, convenient to construct, small in engineering amount and low in cost.
本发明公开了一种预应力混凝土技术加固加高圆形构筑物水池的方法，所述方法包括以下步骤：在水池原池壁外侧环绕设置若干道预应力环梁，水池原池壁外侧设置若干道沿竖直方向延伸的锚固肋，每一道预应力环梁内设置预应力筋，预应力筋的末端穿过锚固肋；进行预应力筋的张拉，预应力筋的末端锚固于锚固肋，对于预应力筋露出的部分进行防腐封闭处理；进行加高构件施工，所述加高构件包括池壁、走道板、中心筒、出水井、出泥井原位置加高。本发明通过较小的工程量，显著地改善圆形水池的受力条件，从而提高其承载能力，实现水池的加固和处理能力提升的效果，是一种结构简单可靠、施工方便、工程量小、成本较小的圆形水池加固加高改造方法。
