Research on the Combination Application of Concrete Construction Robots
In the context of the decreasing labor force in the construction industry and the rapid development of construction robots,promoting the replacement of construction site machines is of great significance.Based on the Changsha Zhigu Yipin Residential Project,the combination of concrete intelligent fabric robot and intelligent leveling robot is applied and tested on site.By comparing the construction efficiency of robot collaborative operation mode,improving positioning and navigation accuracy,and analyzing economic feasibility,the application method and selection decision criteria for the combination of concrete construction robots are formed.The results show that the combination of intelligent fabric robots and leveling robots,using fully automatic intelligent human-machine cooperation mode,has the highest efficiency,reducing the number of concrete workers by more than 3,and improving work efficiency by more than13%;the ICP algorithm can be used to register the robot coordinates with the BIM model coordinates,the maximum error of operation in 200 m2 can be controlled within 25 mm,achieving the accuracy of fully automatic intelligent operation of concrete construction robot combinations;the economic feasibility of the combination application of concrete construction robots can be determined by comparing the direct cost of robot application amortization per cubic meter of concrete pouring with the cost savings of reducing labor per cubic meter of concrete pouring.
