Background
In the process of excavation of a foundation pit or a tunnel or in the use of a dam, especially in the flood season, piping conditions such as water leakage, sand leakage and the like exist. At present, a mode of filling polyurethane into a drill hole is generally adopted for plugging under the condition, but the slow volume expansion of the polyurethane foaming process is difficult to control, the larger water and sand gushing condition is difficult to treat, and a large amount of polyurethane flows out along with water in the grouting process, so that the waste is serious. Meanwhile, the strength of the polyurethane foam is low, the combination of the polyurethane foam and the blocked part is not firm, and the risk of secondary water gushing and sand gushing or dam piping exists. The other two-component liquid plugging materials need to be injected twice, water is blocked at the water leakage position after the contact reaction, and the method cannot realize the full stirring of the two components, so that the strength stability of the blocked position is poor, the cost of the plugging materials is high, and the extruded pipeline and the pipe orifice are easy to be blocked.
The cement-based grouting and plugging mortar is a grouting plugging material commonly used in engineering, and has the main functions of meeting the requirements of engineering construction and operation by plugging grouting or combining other anti-seepage reinforcing means so as to achieve good construction environment and ensure normal operation of the engineering, and is used for large-scale equipment anchoring, embedding of construction joints of underground engineering such as subways, tunnels and the like, reinforcing and repairing of concrete beams and columns and the like. However, in service, leakage is a common engineering problem due to cracking of the lost circulation grouting material caused by various factors.
