Self-propelled construction machine used in road construction, has movable carriage with striker pin and emulsion injection valve for forming fissures on cemented ground or highway and for injecting compact emulsions into fissures

摘要

The machine has portal frame with ends mounted on two self-propelled caterpillars, and chassis storing emulsion heating and injection system, hydraulic section and electricity-generating switchboard. A movable carriage, moving longitudinally on portal frame, has striker pin for performing vertical slide cutting operation and emulsion injection valve associated with emulsion heating and injection system. The machine forms fissures on cemented ground or highway, and injects compact emulsions into fissures without moving on highway surface and spoiling finished surface of highway.
