Sulphate Resisting Concrete (SRC)/ Plain Cement Concrete (PCC) - Used for non structural works such as Blinding, Screeding and Protection works. a. Coping. Pile Foundation is a type of deep foundation that transfers heavy loads from the superstructure to hard strata below the ground. Rigid Frame piers are used when bridges are wide or when piers must be installed to avoid obstacles such as roads. Driven piles are a form of displacement pilling as the soil is displaced by the side of the pile as it is driven in to the ground. A plinth beam is provided at the plinth level and refers to a horizontal structural element that interconnects columns, thereby preventing buckling of columns. They are typically utilized for shallow establishments to convey and spread concentrated burdens caused, for instance, by pillars or columns. Bedding for Footing. American Type. linearly to the ground. Which is the code used for the design of the RCC Bridge?

In this section The Construction Centre provides a directory of relevant specialist contractors and product suppliers. Spread Footing This footing is also known as pad foundation. Lastly, structural engineers need to comprehend how to incorporate support beams, columns and foundations into the substructure plans. It is suitable for all sizes of land. SUB-04 Form work for column. Typical applications for geomembranes are as liner materials, within ponds and at landfill sites. Substructures can be classified into piers (columns), foundations (footings), and abutments. As far as practicable, the foundation should be so shaped and proportioned in such a way that the centre of gravity of the imposed loads coincides with the C.G of the supporting area of the base.
