摘要： A track structure of the rapid track transit, comprises a lower girder (1) and an upper rail level component (2), the rail level component (2) comprises a function district steel component (23) connected with a reinforced concrete plate beam (21) by a fastenings (22). The track structure is characterised in that: 1) the reinforced concrete beam (21) is a minitype component, the multiplex reinforced concrete beams (21) span over the girder (1) lenghways along the line by a linking mechanism (3), furthermore there is an expansion joint (20) between the reinforced concrete beams (21); 2) the linking mechanism (3) comprises the support girder (31), the weld nails (32), the high strength bolts (33) and the steel adapter plate (34), the support girder (31) is connected with the girder (1) by the high strength bolt (33), the steel adapter plate (34) and the steel connecting plate (35), the weld nails (32) at the top of said support girder (31) are inserted into the post-pouring holes (24) of the reinforced concrete beam (21), then concrete is casted after the accurate orientation of the reinforced concrete plate beam (21), thus accomplishing the connection; 3) as to the multiple track, the support transom (11) is located between both sides of the girder (1). The invention is a track structure specially applied in spaning over the micromidi riverway.

摘要： A guideway structure for the high-speed track-bound transportation is composed of the lower-layer main load-bearing girders and the guideway-surface structure elements. The structural elements are connected by the steel elements at the functional zones and the reinforced concrete plates on the guideway body to form an integral. The guideway structure has the following special features:
(1) The reinforced concrete plate girders are elements of small-size type. Many of the reinforced concrete plate girders are longitudinally disposed on the lower-layer main load-bearing girders along the guideway line; Between two adjacent reinforced concrete plate girders is reserved a gap of certain width for expansion and contraction;
(2) The said connection-mechanism is composed of the supporting steel girders, the weld nails, the high strength bolts and the steel bearing plates. The supporting steel girders are connected with the lower-layer main load-bearing girder by the high strength bolts, the steel bearing plates and the connecting steel plates; The weld nails are on the top of the supporting steel girder and deeply inserted into their respective post-poured holes on the reinforced concrete plate girder; The connection will be completed by pouring concrete on-site after the reinforced concrete plate girder has been accurately positioned;
(3) In the case of double-track guideway, between the lateral surfaces of both lower-layer main load-bearing girders are disposed cross beams for supporting purposes.
The invention is one of the guideway structures especially suitable for the guideway structure across a river of medium- or small-width.摘要翻译： 用于高速轨道运输的导轨结构由下层主承载梁和导轨表面结构元件组成。 结构构件由功能区的钢构件和导轨体上的钢筋混凝土板连接成一个整体。 导轨结构具有以下特点：（1）钢筋混凝土板梁是小型的构件。 许多钢筋混凝土板梁沿导轨线纵向设置在下层主承载梁上， 两块相邻的钢筋混凝土板梁之间留有一定宽度的缝隙用于膨胀和收缩; （2）所述连接机构由支撑钢梁，焊钉，高强度螺栓和钢承板组成。 支撑钢梁通过高强度螺栓，钢承板和连接钢板与下层主承力梁连接; 焊钉位于支撑钢梁的顶部，并深嵌入钢筋混凝土板梁上各自的后浇孔内; 钢筋混凝土板梁精确定位后，现场浇筑混凝土即可完成连接; （3）在双轨导轨的情况下，为了支撑目的，在两个下层主承载梁的侧面之间设置横梁。 本发明是一种导轨结构，特别适用于横跨中等或小宽度河流的导轨结构。
