AI Technical Summary

Technical Problem

In special working conditions such as single-track railways, existing concrete placing booms have a large width-to-height ratio, which compresses the working space on top of the trolley. This results in an unequal distance between the installation position of the concrete placing boom and the grouting port. The fixed pipeline needs to be equipped with multiple 90° right-angle bends, which causes a surge in local resistance, sedimentation and blockage, and construction interruption. In addition, the dense pipelines hinder the passage of the trolley.

Method used

Design a material placing machine suitable for large aspect ratios. By setting a transmission pipe on the side of the frame and combining it with a telescopic and rotatable main pump pipe, the material placing machine can travel, rotate, and extend. This reduces the need for fixed pipeline layout. The use of a track system allows the frame to move back and forth on the track, achieving precise material placement.

Benefits of technology

It effectively adapts to construction in narrow cross sections, reduces manual disassembly and assembly of pipes, lowers construction costs, improves construction efficiency, avoids sedimentation and blockage, and ensures continuous pouring operations.
