[0003] For the culvert plugging construction, the existing plugging device has a simple structure and many uncertainties in construction. The usual method is to cast concrete at both ends of the culvert and set end concrete outside the pipe. However, due to the fact that the formwork cannot be effectively installed inside the culvert, the construction operation has great randomness, which leads to unstable density of the concrete inside the culvert and the concrete outside the pipe cannot be cast synchronously with the concrete inside the pipe, thus a construction joint is easily formed. With the increase of grouting pressure, the plugging part of the pipe opening may fail due to the huge pressure, leading to the problem of grout leakage. In addition, the traditional grouting structure also has the risk of non-dense grouting of the culvert top plate and even the formation of cavities, which may cause leakage and threaten the safety of the dike. Therefore, a dike culvert plugging and grouting device is urgently needed to ensure the plugging effect and quality and maintain the safety of the dike. SUMMARY
