Cement-based slurry non-dispersible in water for flowing water plugging and flowing water grouting plugging process
The invention discloses cement-based slurry which is not dispersed when encountering water and is used for plugging flowing water and a flowing water grouting plugging process. The cement-based slurry which is not dispersed when encountering water and is used for plugging flowing water is prepared from water, cement, table salt, triethanolamine and a composite additive, the weight ratio of the water to the cement is (0.75-1.25): 1, the weight of the table salt is 5-10 wt% per mill of the weight of the cement, the weight of the triethanolamine is 0.5-1 wt% per mill of the weight of the cement, and the weight of the composite additive is 3-10 wt% per mill of the weight of the cement. The flowing water grouting plugging process is a process for plugging and grouting flowing water in a roadway or a tunnel by using the cement-based slurry which is not dispersed when encountering water and used for flowing water grouting and water plugging. The cement-based slurry non-dispersible when encountering water for plugging the flowing water has the characteristics of high condensation speed, good early strength and strong cohesiveness and integrality, also has relatively strong non-dispersible when encountering water, and can be used in grouting and water plugging construction of the flowing water ground.
本发明公开动水堵水用水泥基遇水不分散浆液及动水注浆封堵工艺，动水堵水用水泥基遇水不分散浆液由水、水泥、食盐、三乙醇胺和复合添加剂组成；水与水泥的重量之比为0.75～1.25:1，食盐的重量为水泥重量的5wt‰～10wt‰，三乙醇胺的重量为水泥重量的0.5wt‰～1wt‰，复合添加剂的重量为水泥重量的3wt‰～10wt‰。动水注浆封堵工艺是利用上述动水注浆堵水用水泥基遇水不分散浆液对巷道或隧洞中的动水进行封堵注浆的工艺。该动水堵水用水泥基遇水不分散浆液具有凝结速度快、早强性好、粘聚性整体性强的特点，同时具有较强遇水不分散性能，可以用于动水地面注浆堵水施工中。
