Repairing structure of stilling pool bottom plate structural seam
The invention belongs to the field of water conservancy and hydropower engineering, and particularly discloses a repairing structure for a stilling pool bottom plate structural seam. The repairing structure is high in high-speed water flow pulsating pressure damage resistance. According to the repairing structure, an upper repairing groove and a lower repairing groove are formed through grooving, and a seam pressing rod is arranged at the position, located at the bottom of the lower repairing groove, of the lower portion of a structural seam; plastic water stopping filler is arranged in the lower repairing groove, and meanwhile newly-poured anti-abrasion concrete with the upper portion of the structural seam reserved is arranged in the upper repairing groove; and a water stop part for cutting off the upper part of the structural seam is arranged in the newly cast anti-abrasion concrete, so that on one hand, the erosion damage areas on the two sides of the structural seam of the stilling pool bottom plate can be effectively repaired, and on the other hand, the water stop and erosion resistance of the repaired structural seam can be improved, so that the structural seam has relatively strong high-speed water flow pulsating pressure damage resistance.
本发明属于水利水电工程领域，具体公开了一种抗高速水流脉动压力破坏能力较强的消力池底板结构缝的修复结构。该修复结构通过刻槽形成上部修复槽和下部修复槽，并在位于下部修复槽底部的结构缝下部处设置有压缝棒，在下部修复槽中设置塑性止水填料，同时在上部修复槽中设置预留有结构缝上部的新浇抗冲磨混凝土，并在新浇抗冲磨混凝土中设置截断结构缝上部的止水部，一方面能够对消力池底板结构缝两侧的冲蚀破坏区进行有效修复，另一方面可以提高修复后结构缝的止水和抗冲蚀能力，使其具有较强的抗高速水流脉动压力破坏能力。
