Abstract
Non-water reactive polymer grouting technology is an important means to control water-induced engineering disaster emergency rescue. However, the time-varying viscosity of polymer slurry and the expansion force of slurry reaction are the main factors affecting the grouting treatment effect. Therefore, it is necessary to study the time-varying viscosity of polymer slurry and the expansion force of slurry reaction. Firstly, the expansion rate of polymer slurry with different expansion ratio is tested and checked by the self-made expansion rate measuring cylinder. Then, the reaction expansion force and viscosity of polymer slurry with different expansion ratio are tested and studied by the expansion force testing device and NDJ-5T digital rotational viscometer. The results show that the expansion rate of polymer slurry used in this paper is basically the same as the factory instructions At the same time, the viscosity of polymer slurry increases exponentially with time, and the curve is steeper, that is to say, the viscosity increases rapidly with time.
Highlights
China has a huge scale of infrastructure projects
There are many public facilities in service and under construction, such as roads, railways, airports, dams, reservoirs, etc., which are usually accompanied by engineering diseases
In view of the above diseases, Zhengzhou University has developed a complete set of high polymer grouting technology and equipment, which has shown good performance in emergency rescue, repair and protection of engineering diseases caused by water
Summary
China has a huge scale of infrastructure projects. There are many public facilities in service and under construction, such as roads, railways, airports, dams, reservoirs, etc., which are usually accompanied by engineering diseases. Bian Xuecheng et al [6] applied high polymer grouting technology to the repair of high-speed railway subgrade, Shi Mingsheng et al [7] developed high polymer anchor and carried out experimental research on its bonding performance with silt, both of which proved the remarkable effect of polymer on the reinforcement and repair of engineering infrastructure. Shi Mingsheng [2] once pointed out that the high polymer slurry has significant rheological property, that is, the time-varying viscosity of the slurry. According to the actual needs of the project, several kinds of high polymer grouting materials with different expansion ratio are tested for expansion force and viscosity in this paper, in order to provide a reference for the development and application of high polymer grouting technology
