运营期渗漏水隧道注浆材料适用性
Application on different types of cementitious grouts for water-leakage operational tunnels
摘要
Abstract
The main performance parameters of four types of cement-based grouts for operational tunnels were studied based on the grouting requirements for grouts in water-leakage operational tunnels. The Kaiyuan Tunnel situ-tests with three similar geological conditions were designed. The ordinary portland cement, microfine portland cement and polymer cement were used for grouting. The grouting effects of different grouts for the water-leakage operational tunnel were evaluated based on the analysis results of radar detections. According to the feasibility of grouting technology, grouting effects and economical efficiency, the suitability of grouts for different water-leakage conditions in operational tunnels were analyzed. The results show that the fluidity, concretion rate and consolidation strength of polymer cement are satisfied, and the plugging effects of polymer cement for water-leakage channels are excellent in situ-tests. The microfine portland cement is suitable for the water-leakage areas with micro pores or micro cracks, and the polymer cement can be applied to the water-leakage areas with concentrated fissures or surface seepage zones. The portland cement can be used for areas with large or wide holes, and the cement−water glass slurry is suitable for areas with large flow or high pressure.关键词
