Railway PSC Slab| Concrete, BBS, Ballast Retainer रेलवे PSC स्लैब पूरी जानकारी

#pscslab #railways #rdso This video provides a detailed explanation of Prestressed Concrete (PSC) slabs used in railway bridges, overbridges, and underbridges. The video covers the definition of PSC slabs, the role of ballast retainers, and how to calculate concrete and reinforcement quantities for both (0:14). It also explains how to determine the steel quantity for prestressing steel strands and interpret actual RDSO standard drawings for PSC slabs (0:24). Here's a breakdown of the key topics: • PSC Slabs Explained (0:39): • PSC slabs are pre-stressed concrete slabs (0:59) where steel cables or tension are introduced before or after concrete pouring (1:14). • This process induces compression, which helps manage the heavy, dynamic loads from trains, preventing cracks and ensuring durability (1:27). • Using PSC slabs controls cracking, making them long-lasting and low-maintenance compared to traditional RCC slabs (1:39). • Ballast Retainer's Role (1:58): • Ballast retainers are L-shaped walls or curbs on the sides of PSC slabs that stabilize the railway track (2:00). • They retain the ballast, the crushed stone material that supports the track (2:22). • Concrete Quantity Calculation (2:32): • The video demonstrates how to calculate the concrete quantity for PSC slabs and ballast retainers using an Excel sheet (2:41). • It highlights that PSC slabs typically use M45 grade concrete, while ballast retainers use M35 grade (3:08). • The concrete quantity for a 9.15-meter span PSC slab is approximately 23.618 cubic meters (4:37), and for the ballast retainer, it's about 28.626 cubic meters (5:36). • Prestressing Steel Quantity (5:47): • The video details the process of calculating the quantity of prestressing steel, including the 12.7 mm diameter wires and the number of strands per cable (6:30). • Each cable consists of 12 strands, with an additional "emergency" strand in the last two cables (7:41). • The overall length of each cable is around 10.958 meters, not the span length, because of its U-shape (8:08). • The total steel quantity for 68 PSC slabs is approximately 47.589 metric tons (10:36). • Bar Bending Schedule (BBS) (12:13): • The video also briefly discusses the Bar Bending Schedule for reinforcement in both the ballast retainer and the slab (12:15). • It advises cross-verifying the standard BBS calculations for accurate billing (12:26). • Sleeper Specifications (17:11): • The video mentions the use of monoblock sleepers (Type 1) in conjunction with the PSC slabs, noting their specific material and concrete grade requirements (17:44).
