The sealing strip 13 prevents escape of grout from under the front edge surface of the slab unit, thereby preventing staining of the front wall 14. 7. A platform structure as claimed in any of claims 28 to 42, in which each longitudinal beam supports at least two platform units. Platform Construction. (6) The slab units 1 are craned in and mounted on the supporting structure constituted by the cross beams 38 and longitudinal beams 42. 36. Exemplary dimensions, in millimetres, are indicated in Figures I to 4. the upper surface comprising a forward portion, on which edge copers are to be mounted, and a rearward portion, with a step rising between the forward and rearward portions, the forward portion being planar. A 100 lb double headed rail is shown in the figure. A method as claimed in any of claims 14 to 20, in which each edge coper weighs at most 25 kg. 14. A railway station platform structure comprising a plurality of units according to any of claims 1 to 13 arranged side by side. It may also be possible to combine the tactile paving elements with the edge copers, or to omit the tactile paving elements. Frequency of use: Type 1 > 50,000 incoming passengers/day (very large stations). A unit as claimed in any preceding claim, in which the length of the unit from front to rear is at least as great as its width. A drainage outlet 28 is provided in the front surface of the plinth 27. Therefore, trains could call at Downpatrick or use the avoiding line with connections for passengers and goods at the Loop Platform, thereby making the railway operationally from a signalling point of view, more efficient using a railway triangle . Railway stations can be classified according to their: Territorial size. The forward portion 4a of the upper surface has the same dimensions as in Figures 1 to 5, but there are no grout holes. Mechanical Method Railway Track Construction. Depending on the size of the edge copers, more or fewer may be used, although there are preferably at least four. A platform substructure as claimed in any of claims 29 to 34, in which the cross beams are integral with the longitudinal beams. Refurbishment of an exiting platform may be performed by excavating a region 22 of the platform surface to the front edge, installing a prefabricated platform unit 1 in the excavated region, and installing edge copers 23. 24. sections and support plates with legs, corresp. In this case, the rearward portion 4b of the upper surface 4 is of greater length, has a more gradual slope (1 in 50) from front to back, and has a raised plinth 27 near the rear edge surface 7 of the slab unit 1. 27. In one aspect the present invention provides a prefabricated unit for construction or refurbishment of a railway station platform, the unit having a stepped upper surface, front and rear edge surfaces, and side edge surfaces. The bottom surface of the slab unit I has integrally cast projections 32 for a purpose to be explained below. To assist installation, temporary lifting rings (not shown) can be fitted to anchorages (not shown) located in or near the plinth 27 and in the forward portion 4a of the upper surface of the slab unit. The new platform is first on the market to gain type approval from Network Rail. 46. The joints between adjacent units are sealed by a dry rubber O-ring which, when compressed, forms a watertight seal. iLECSYS' platform is a module construction suitable for a wide range of railway applications, and the light weight of the constituent material and the fact that GRP profiles and gratings can be machined on site mean that the platforms can be installed in next to no time. Passenger Platform. A method of constructing a railway station platform structure, including the steps of : (a) constructing foundations alongside the railway; (b) constructing upstanding supporting members on the foundations; and (c) mounting on the supporting members a prefabricated superstructure comprising cross beams mounted on the supporting members so that the cross beams have cantilevered portions extending beyond the supporting members towards the railway, longitudinal beams on the cross beams, and platform units on the longitudinal beams, side edge surfaces of the units extending away from the railway and front edge surfaces of the units extending along the railway beyond the ends of the cantilevered portions of the cross beams. (3) In situ concrete support columns 37 are constructed on the strip foundations 36 and incorporate vertically projecting corrosion resistant threaded tie bars of 16 mm diameter (not shown in Figure 8). A prefabricated slab unit 1, primarily for use in the refurbishment of an existing platform, is shown in Figures 1 to 4; it is a pre-cast concrete unit incorporating a reinforcing mesh 2. a dead-end or siding. 35. A platform structure as claimed in any of claims 29 to 33, in which the cross beam are connected to the supporting members solely by mechanical connection devices. iLECSYS in the UK have designed and constructed a new type of platform for Britain's railways using GRP composite from Fiberline. (H) Finally the temporary fencing 34 is removed. We evaluate environmental and operator safety factors in all of our platform designs to ensure customer satisfaction. 11. • Feasibility studies are carried out for wide range of different types of railway projects • List is not exhaustive, but indicates projects which have recently been studied/planned, or are currently underway in Asia • Development costs range from nearly $100 million per route-km for construction of new urban Railway Track and Platform Drainage Systems. Accordingly, the copers 23 are small enough to be handled without undue strain, preferably weighing at most 25 kg if they are made of pre-cast concrete and being substantially lighter if they are made of less dense materials, for example plastics material. One side edge surface 9 has a key formation 29 for fitting in a recess or groove 31 in the opposite side edge surface 8 of an adjacent slab unit so as to prevent relative vertical movement of the adjacent slab units. 10. A platform structure substantially as described with reference to, and as shown in, Figures 7 and 8 or Figures 9 and 10 of the accompanying drawings. A platform structure as claimed in any of claims 29 to 45, in which each platform unit is elongate in the direction away from the railway. This method is extensively used in Britain and America by using special track laying machine. 52. This invention relates to the construction of platforms for railway stations. Technical Construction Company, Muzaffarnagar UP - Real Estate / Builders / Contractors of railway over bridge construction service, railway platform renovation service & railway building construction service in Muzaffarnagar, Uttar Pradesh. In another aspect the invention provides a railway station platform structure comprising: foundations alongside the railway; upstanding supporting members rising from the foundations; cross beams mounted on the supporting members and having cantilevered portions extending beyond the supporting members towards the railway; longitudinal beams on the cross beams, each longitudinal beam extending between a pair of the cross beams, there being at least two longitudinal beams between each pair of cross beams, at least one of these longitudinal beams being on the cantilevered portions of the cross beams and at least one of these longitudinal beams being remote from the cantilevered portions; and platform units on the longitudinal beams, the platform units having side edge surfaces extending away from the railway and having front edge surfaces extending along the railway beyond the ends of the cantilevered portions of the cross beams.
