AI Technical Summary
In the construction of concrete subbase, existing rollers can cause excessive pressure on high convex parts, which can lead to excessive compression of sand particles and the formation of local hardening. Insufficient pressure on low-lying parts can result in substandard material density, leading to poor surface flatness and easy settlement and cracking of the upper concrete.
A compaction roller for concrete subbase construction was designed, comprising a compaction mechanism and an auxiliary mechanism. Through a limiting plate, an adjusting plate, a push plate, and a worm gear transmission system, the angle of the push plate can be precisely adjusted and fixed. The counterweight can adjust the compaction pressure. The auxiliary mechanism flattens the surface of the subbase and improves its flatness.
It improves the surface smoothness and compaction quality of the concrete subbase, enhances the reliability and efficiency of construction, adapts to different construction needs, ensures the density of the material, and prevents settlement and cracking.
