Construction road maintenance device and reinforcement method thereof
2016
The invention discloses a roadbed below a concrete road plate. Due to insufficient filled-soil compactness, local cavities are generated between the road plate and the base, support for the roadbed is lost, and broken slab on a concrete road is caused. The invention provides a construction road maintenance reinforcing device which has a simple structure and is convenient to operate. The invention also discloses a reinforcement method by utilization of local cavities generated between the concrete road and the base. The device comprises an air bag and a tip layering device. A force pump is used for pressurization; the air bag device rises under force; the tip layering device rises; an individual block body rises under force; and a slip casting machine is used for slip casting so as to fill the local cavities between the concrete road and the base. Then, strength of the reinforced road is consistent with strength of the original road. In addition, operation is simple.
