What Can I Do For You?
concrete the posts after confirming they are at an equal level. recheck the distance between each post and fill the hole with concrete containing a mixture of cement, gravel, and sand up to 600 mm from the top. install sleepers and backfill. wait for a day for the concrete to dry. slide the sleepers into the posts the next day.

a concrete sleeper can weighs up to 320 kg (700 lbs) compared with a wooden sleeper which weighs about 100 kg or 225 lbs. the spacing of concrete sleepers is about 25% greater than wooden sleepers. another type of concrete sleeper is shown in this drawing (left). this is the twin-block sleeper. the design consists of two concrete blocks

securely and reliably embedded in a monolithic concrete slab. highly elastic rail fastenings are essential to achieve the verti-cal rail deflection required for load distribution and for smooth train travel. the b 355-m sleeper the b 355-m sleeper represents the core of the rheda 2000® system. due to mass production of these precast components,
maximizer concrete mix. masonry work. calculated results will reflect how many bags are needed for block and brick. enter the number of bricks (8' x 2' x 4') or blocks (8' x 8' x16') in the box below that you plan to use for your project. the calculator will then tell you the number of bags you need based on the different size of bags we carry.

slab track coenraad esveld,professor of railway engineering, delft university of technology delft with the design of railway lines factors like life cycle cost, construction time, availability and durability play an increasingly important role. in this respect, non-ballasted track concepts offer good opportunities. fig. 1: shinkansen slab track
the ballast support condition back-calculator (hereafter referred to as the “back-calculator”) analyzes concrete sleeper flexural data recorded under revenue service traffic to indirectly quantify both the ballast support condition beneath concrete sleepers and the pressure at the ballast-sleeper interface (qian et al., 2019).
• precast concrete non-load bearing façade panels. • precast concrete floor system, either: - precast concrete beams and precast slabs (reinforced concrete or prestressed) with a composite in-situ topping or precast concrete walls with precast concrete slab system figure 3.1 precast prestressed slabs spanning between walls with composite
turnout sleepers made of concrete with under sleeper pads. railroad ties, crossties or railway sleepers support rails in railroad tracks. under sleeper padding for concrete bearers in ballasted track increases the track stability, protects the ballast and reduces structureborne noise and airborne noise by reducing rail damage to the running surface of the rails.
