Abstract
Description
Technical Field
[0001] The utility model relates to a concrete sleeper forming mould, in particular to a IIId type concrete sleeper forming steel mould. Background Art
[0002] At present, prestressed concrete wide sleepers are mainly used on railways. Wide sleepers are widely used in railway tunnels, railway platforms, and special freight unloading platforms. Due to the large bottom area of wide sleepers, they can effectively reduce the stress and deformation of ballast. In addition, due to their heavy weight, the friction at the bottom is enhanced, and the track deformation is greatly reduced compared with wooden or concrete sleepers. At the same time, the gaps between sleepers are small, the roadbed is not easy to get dirty, and the appearance is neat. It has been widely used since 1982.
[0003] With the development of my country's railway industry, the railway operation speed is getting higher and higher, and the cargo capacity is also getting larger and larger. The problem of wide sleeper ballast bed has gradually become prominent. Due to the small gap between wide sleepers, it is difficult to use large-scale road maintenance machinery for cleaning and screening operations, and maintenance and repair are difficult. There are dirty particles between the pores of the ballast. The particles and water easily compact the ballast bed. It is difficult to use large-scale road maintenance machinery to clean and screen the ballast, resulting in a large number of dirty particles between the pores of the ballast. Under the joint action of water, the ballast bed is prone to compaction, which leads to a decrease in the elasticity of the ballast bed, an increase in the support stiffness, and an intensification of the vibration and impact of the train, causing the line to be uneven, increasing the workload of line maintenance and repair, and in serious cases, threatening the safety of train operation.
[0004] In view of the various problems existing in the above-mentioned wide-sleeper trackbed, since the bottom area of the sleeper of the type IIIa rail is widened, the supporting area under the sleeper and the end side area are increased, which can greatly reduce the cumulative deformation of the trackbed. Therefore, in the face of damaged trackbed, only type IIIa concrete sleepers can be used to replace the wide sleepers. During construction, the line plates are placed directly on the sleepers, resulting in high and low levels in the line plates installed above, and the flatness of the line plates cannot be guaranteed. In this way, the constructed trackbed has no aesthetics, especially in large urban stations, which have high requirements for the beauty of the stations and cannot meet the needs.
[0005] Therefore, it is necessary to develop a ballast structure that is convenient for ballast maintenance and can beautify the station. For this purpose, a Ⅲd type concrete sleeper is designed. On the basis of the Ⅲa type sleeper, a shoulder is added to the sleeper. The track plates are placed on the shoulders of the two sleepers, so that multiple track plates remain flat, which increases the aesthetics of the ballast and facilitates the sealing between the track plates, thus beautifying the station. In order to implement the above scheme, it is necessary to make Ⅲd type sleepers first, and the production of Ⅲd type sleepers requires forming steel molds. Utility Model Content
