输水洞工程是一种常见的工程形式,在施工中应通过运用科学的方法,有效的控制手段,及时发现施工中的异常现象并采取措施加以调整,防止质量不合格产品的出现,以确保工程质量。为此,要抓住控制过程中影响质量的主要因素,以便达到良好的控制效果。1输水洞开挖质量控制要点洞内采用全断面一次开挖成形,其要求如下:洞口削坡应自上而下进行,严禁上下垂直作业。同时应做好危岩处理,坡面加固,马道开挖及排水等工作。进洞前,须对洞脸岩体进行 Water tunnel project is a common form of engineering, in the construction should be through the use of scientific methods and effective control measures, timely detection of anomalies in the construction and take measures to be adjusted to prevent the emergence of substandard quality products to ensure that Engineering Quality. To this end, we must grasp the main factors that affect the quality control process in order to achieve good control effect. 1 Water Tunnel Excavation Quality Control Points Full-face excavation using a full-length excavation, the requirements are as follows: Cutting slope should be carried out from top to bottom, vertical work is strictly prohibited from top to bottom. At the same time should do a good rock handling, slope reinforcement, horse road excavation and drainage work. Into the hole, the face of rock to be carried out
