【摘要】：地下厂房防渗排水工程的关键是帷幕灌浆工程,因此做好帷幕灌浆工程管理,保证灌浆施工质量对地下厂区的防渗极为重要。针对目前水电建设市场现状,提出了统一灌浆自动记录仪、大力推行第三方质量检查和建立灌浆工程奖惩机制等灌浆工程项目管理措施,地下厂房左、右岸帷幕灌浆施工质量总体良好,各条廊道渗水总量远小于设计标准,但由于设计、地质及施工等多方面原因,部分施工支洞、灌排廊道局部排水孔渗水较大,实施灌排廊道补强灌浆和压力管道下弯段混凝土化学灌浆封堵后,使渗水情况得以解决,研究结果对相关工程有重要参考价值。
[Abstract]:The key of seepage prevention and drainage project of underground powerhouse is curtain grouting project. Therefore, it is very important to ensure the quality of grouting construction to prevent seepage in underground factory area, aiming at the present situation of hydropower construction market. The paper puts forward the unified grouting automatic recorder, vigorously carries out the third party quality inspection and establishes the grouting engineering reward and punishment mechanism and other grouting project management measures. The construction quality of the curtain grouting on the left and right bank of the underground powerhouse is generally good. The total amount of water seepage in each corridor is far less than the design standard, but due to many reasons, such as design, geology and construction, part of the construction branch hole, irrigation and drainage corridor local drainage hole seepage is larger. After the reinforcement grouting of irrigation and drainage corridor and the sealing of concrete under the pressure pipe by chemical grouting, the water seepage can be solved. The research results have important reference value to the relevant engineering.
