Abstract: PURPOSE: A quick construction method of a rigid reinforcement roadbed using an assembly panel and a filler and a rigid reinforcement roadbed rapidly constructed by the same are provided to be easily applied to a downtown area et cetera in which securing a site is difficult by enabling a rapid construction and to improve the stability of a rigid reinforcement roadbed. CONSTITUTION: A rigid reinforcement roadbed includes a banking portion(200) and a side wall body(100). The banking portion is constructed by successively laminating a banking layer(220) by using a reference frame(210). The side wall body is constructed in the one side or both sides of the transverse direction of the banking portion, and supports the banking portion.

Abstract: PURPOSE: A track structure with a concrete-filled steel pipe and a construction method thereof are provided to control track irregularity by directly installing a rail fastener on a concrete-filled steel pipe. CONSTITUTION: A track structure(100) using a concrete-filled steel pipe comprises two rails(110), steel pipes(120), spacers(130), rail fasteners(140), base plates(150), fixing studs(160), and fill concrete. The rails guide the wheels of a train. The steel pipes are installed on the bottoms of the rails and support the load of the train. The spacers are welded between the steel pipes to maintain the gap between the rails. The rail fasteners elastically fasten the rails to the tops of the steel pipes. The base plates are attached to the surfaces of the steel pipes and fix the rail fasteners to the steel pipes. The fixing studs fix the base plates to the top surfaces of the steel pipes. The fill concrete is filled in the steel pipes to reduce vibration.

Abstract translation: 目的：提供一种具有混凝土填充钢管的轨道结构及其施工方法，以通过在混凝土填充的钢管上直接安装轨道紧固件来控制轨道不规则性。 构成：使用混凝土填充钢管的轨道结构（100）包括两个轨道（110），钢管（120），间隔件（130），轨道紧固件（140），基板（150），固定螺栓（160） ，并填充混凝土。 导轨引导火车的车轮。 钢管安装在轨道的底部，并支撑列车的负载。 间隔件焊接在钢管之间以保持轨道之间的间隙。 导轨紧固件将导轨弹性地固定到钢管的顶部。 底板附着在钢管表面，将钢轨紧固件固定在钢管上。 固定螺柱将基板固定在钢管的顶面上。 填充混凝土填充在钢管中以减少振动。

Abstract: PURPOSE: A sleeper for decreasing irregularity of a track is provided to prevent an accident by preventing the distortion of a rail by maximizing frictional force between a sleeper and gravel, to prevent the maintenance expenses for a track and to improve the speed of a train. CONSTITUTION: The sleeper for decreasing irregularity of a track contains rail grooves(1) formed on both upper parts to narrow toward the lower part, and a friction unit(10) formed to increase the frictional force with gravels between sleepers, wherein the friction unit(10) contains a curved surface(11) formed toward the center of the straight sleeper.

Abstract translation: 目的：提供减少轨道不规则性的卧铺，以通过最大化轨枕和砂砾之间的摩擦力来防止轨道变形，以防止轨道的维护费用并提高列车的速度。 构成：用于减小轨道不规则性的轨枕包括形成在两个上部上的轨道槽（1），以朝向下部变窄;以及摩擦单元（10），其形成为增加轨枕之间的砾石的摩擦力，其中摩擦单元 （10）包括朝向直轨枕的中心形成的曲面（11）。
