Method for supporting ultra-thin roof roadway under goaf

This patented device solves problems such as over-pressured roads caused by heavy traffic or poorly formed lanes due to rocks falling into them during construction work. It uses an expandible tube made up of two parts - one part contains a spring mechanism for adjustability and another part holds a rubber material called a cushing block. When there're no weight on it, they stay at their original position because they don’t compress too much like regular pneumatic tubings used today. However if someday some heavier objects fall onto this new design, the force from gravity causes the bottom section to break down create cracks within the structure without being able to absorb any more energy than usual. By adding a special type of anchoring system, which helps stabilizing these areas around the crack opening, the supporting effect becomes even stronger against impact loads. Additionally, the patents propose various methods for filling the space between the tire ring and the ground surface before casting concrete, resulting in improved load distribution and increased bearing capacities. Overall, the technical effects include efficient and reliable support systems for vehicles equipped with wheels, enhancing safety standards, preventive maintenance costs reduction, better vehicle performance, lessened damage to nearby structures, and lower risk of accidents associated with unsteady pavement conditions.

This patented technology describes how to safely support tunneling cars during excavation operations on highly-thin or thick walls that may develop cracks over time caused by repeated stress cycles like drilling holes through soil layers. Current methods involve use channels made up mostly of iron wires embedded into concrete slabs, but this method has limitations such as being too rigid at times causing damage to other structures near them while also requiring extra work effort compared to more flexible alternatives like metal pipes.
