Precast concrete assembling road construction method
The invention provides a precast concrete assembling road construction method. According to the construction method, precast blocks are conveyed to a paving area in advance; firstly, the first precast block is placed at the right position through hoisting; when the second precast block is paved, the Z-shaped side wall of the second precast block is spliced with the Z-shaped side wall of the first precast block paved in the former step in a meshing manner; the assembling of the left precast blocks can be completed according to the same manner; after the assembling of the precast blocks is completed, a gap between the adjacent precast blocks is filled cement paste till the cement paste is 50 mm away from the road surface, and then surface finishing is carried out through mortar to enable the gap between the adjacent precast blocks to be flush with the precast road surface; when temporary road needs to be dismantled after the engineering is finished, hoisting rings in the precast blocks are cleaned up firstly, then each precast block is pried to be loose and shifted through a crow bar, and finally a crane hooks the hoisting rings to hoist and convey the precast blocks. The precast concrete assembling road construction method is easy and low in cost; the road formed by assembling the precast blocks is high in loading capacity; meanwhile, the precast blocks can meet use requirements of repeated and long-term transportation, and are simple in manufacturing and good in durability.
