SUBSTRUCTURE CONSTRUCTION METHOD FOR EXISTING RAILWAY USING AUGER AND MOVING APPARATUS

摘要

PURPOSE: A construction method of a lower structure of a railway using an auger and a bogie is provided to perform excavation without the cutting of a rail. CONSTITUTION: A construction method of a lower structure of a railway using an auger and a bogie is as follows. A horizontal beam(130) is arranged on the tops of bogies(110), and a hydraulic device(190) is installed thereon. The hydraulic device is horizontally moved along the horizontal beam between the bogies. One or more augers(150) and cross beams(210) are arranged under sleepers(340). An auger drive device(160) powers the augers to excavate soil, and the cross beams are inserted into the excavation portion. The augers and the cross beams are connected together using the hydraulic device and the motor(180) of the auger drive device. The hydraulic device horizontally moves the auger drive device, and the motor of the auger drive device vertically moves the auger drive device. After the installation of the cross beams is completed, a lower structure of a railway is built. [Reference numerals] (AA) The connection detail of horizontal beams
