文章结合河南省内乡县打磨岗灌区烟草水源工程雲露湖水库碾压混凝土大坝帷幕灌浆施工,在有代表性的廊道地段进行帷幕灌浆试验,采用自下而上的灌浆施工方法,提出孔深、孔距、浆液方式、灌浆压力、灌浆配比等技术参数,来论证帷幕灌浆试验方案和施工参数在技术上的可行性、施工效果的可靠性、经济上的合理性,以指导全段帷幕灌浆施工,确保其满足设计要求。
Based on the curtain grouting construction of the Yunluhu Reservoir RCC dam, which is located at the Bejing Jingang Irrigation Area in Neixiang County, Henan Province, the curtain grouting test was carried out in representative corridor sections. The bottom-up grouting construction method was put forward Hole depth, hole distance, slurry method, grouting pressure, grouting ratio and other technical parameters to demonstrate the curtain grouting test program and construction parameters in the technical feasibility, construction reliability, economic rationality to guide the whole Section curtain grouting construction to ensure that it meets the design requirements.
