溪洛渡泄洪洞是溪洛渡水电站的主要泄洪设施之一,具有高水头、高流速、大泄量的特点,因此,对其质量要求非常严格,但由于工程量大,施工中难免出现混凝土质量缺陷,而高速水流区混凝土的任何缺陷都将会导致在高速水流下产生严重的掏刷、磨蚀、空蚀等单一或多种形式的联合破坏,直接危害工程的安全运行和寿命,本文对溪洛渡右岸泄洪洞过流面混凝土各类缺陷修补材料及工艺进行阐述。
The Xiluodu spillway tunnel is one of the main flood discharge facilities of Xiluodu Hydropower Station. It has the characteristics of high head, high flow rate and large amount of discharge. Therefore, its quality is very strict. However, due to the large amount of construction, concrete quality defects inevitably occur in construction. Any defect of concrete in high-speed water flow area will lead to single or multiple joint damage such as digging brush, abrasion and cavitation seriously under the high-speed water flow, directly endangering the safe operation and life of the project. Overcurrent concrete defects of various types of materials and process repair described.
