The roadbed of the Shandong section of the expressway has collapsed and subsided. It is urgent to restore the road! At our company’s site of the crawler-mounted grouting reinforcement drilling machine, the drilling and grouting unit does not require complex site layout. Once on site, it can be quickly set up. The drill bit penetrates the damaged roadbed layer, and the grouting drill pipe simultaneously delivers the cement slurry, targeting the filling of roadbed cavities and compacting the loose areas. The integrated drilling and grouting operation avoids the cumbersome process of “removal, filling, and pressing” in traditional construction. It can complete the emergency repair of multiple roadbed sections in a single day, and the strength of the repaired roadbed recovers rapidly.

We bid farewell to the traditional step-by-step operation of “drilling, moving the machine, and grouting”, achieving seamless connection of “drilling – grouting”, without waiting for equipment switching and workstation adjustments. The construction time at a single point is shortened by more than 40%, and the daily operation volume is increased by 50% compared to separate equipment. Its advantages are significant in the context of accelerating construction schedules. It can meet the vehicle passage requirements in a short period of time, minimizing the impact of traffic disruptions to a large extent.
