Double-H-shaped concrete rail beam of rubber-tyred tram and construction method thereof

Abstract

The invention discloses a double-H-shaped concrete rail beam of a rubber-tyred tram and a construction method threof. The double-H-shaped concrete rail beam is arranged on piers and comprises a plurality of guide rail beam span sections, and every two adjacent guide rail beam span sections are connected in a chaining mode. Each guide rail beam span section comprises four webs, two bottom plates and a transverse partition plate; the four webs and the two bottom plates are combined into a double-H-shaped structure and are connected and combined into an integrated structure through the transversepartition plate; each web plate is of a structure with an I-shaped cross section, and embedded wear-resistant steel plates are arranged at the top end of each web plate and one side end of the top ofeach web plate; each transverse partition plate is located below the bottom plates and comprises two end transverse partition plates and a plurality of middle transverse partition plates. The two endtransverse partition plates are located at the two ends of each guide rail beam span section, and the multiple middle transverse partition plates are sequentially arranged. Compared with an existingsteel guide rail beam, the double-H-shaped concrete rail beam is large in overall rigidity, good in driving comfort, low in noise, good in durability of a concrete structure and small in later maintenance amount.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a double H-shaped concrete track beam for a rubber-tyred tramcar and a construction method thereof. Background technique [0002] Yunba is a guide-rail rubber-tyred tram with a transport capacity of 0.6 to 10,000 person-times per hour. It is a small-capacity rubber-tyred tram system and a new system in modern trams. It can improve the level of public transportation, supplement product gaps, and is committed to building a multi-level public transportation network. In recent years, it has been planned into a large number of traffic trunk lines in small and medium-sized cities and traffic branches in large and medium-sized cities. At present, the first Yunba Line is under construction in Bishan, Chongqing. The project uses BYD steel guide rail beams. [0003] Yunba is a new thing in recent years. There are mainly two types of beams used in some Yunba's early projects. Th...

AI Technical Summary

Problems solved by technology

Although the steel guide rail beam launched by BYD is light in weight, the steel guide rail beam has the characteristics of low rigidity, poor driving comfort, relatively loud noise, high cost, and large amount of later maintenance.

Adding steel guide rails on the top of conventional concrete box girders can facilitate the maintenance of the structure, but the structure is heavy, the cost is high, and the construction convenience is poor. It is wasteful to install steel guide rail beams separately on the top of the beams.
