PROPULSION DEVICE USING SELF- ASSEMBLY STRUCTURE

摘要

PURPOSE: A top propulsion device using a built-up structure is provided to discharge soil through a built-up structure and to push a leading end propulsion assembly to an excavation direction. CONSTITUTION: A top propulsion device using a built-up structure comprises a linear conductor assembly(100) and a roller(200). The linear conductor assembly is located on the leading end of multiple prefabricated structures(10) locating mostly in front. The linear conductor assembly includes a conveyor(150). The conveyor rearwards transfers the soil and bed rock excavated by an excavator(110). The roller supports the linear conductor assembly and the prefabricated structure to slide-move.
