This solves the problem that when it rains, water will flow along the filler layer into the first stable plate and the second stable plate, and then penetrate into the roadbed from the first stable plate and the second stable plate, flushing the soil under the roadbed, causing the soil under the roadbed to loosen, and the roadbed piles cannot provide good support. Therefore, the roadbed will still have the problem of settlement, but the anti-movement effect of the roadbed piles is not good enough. If the roadbed piles move, it is easy to cause damage to the highway. Utility Model Content
