METRO RAIL - THE DREAM PROJECT OF HYDERABADMISSION HMR “To create an efficient,safe,reliable,economical & world class public transportation system in Hyderabad which will facilitate the city’s transformation as a competitive global city with high quality of life.” WHY METRO Population stands at 8 million and is projected to touch 13.64 million by 2021. Currently, over 2.8 million personalized vehicles ply on Hyderabad roads, with an addition of 0.20 million vehicles every year. 8 million motorized trips are made every day, of which, only about 3.36 million or 42% are made by the Public Transportation System (PTS) i.e., buses and local trains. That means the rest of the trips are made by personal vehicles leading to traffic bottlenecks, high pollution levels and a steep increase in fuel consumption. SOLUTION The answer lies in Mass Rapid Transit System (MRTS). Accordingly, the development of Metro Rail was approved for 71.16 km., covering three high density traffic corridors of Hyderabad. The Project will be developed on BOT basis in PPP mode. P-P-P MODE Public Private Partnership . 16 kms. Asia’s first elevated guide way accommodating two rail lines. Longest elevated MRTS project in ASIA. .

STEPS INVOLVED IN PIER CONSTRUCTION Excavation Foundation and reinforcement Shuttering Erection of pier cap reinforcement Concreting & compaction of concrete by layers Deshuttering Curing . EXCAVATION •Excavation is done by earthmoving equipment up to required area •Excavated earth is dumped in city outskirts . If the soil is weak. a Controlled Low Strength Material (CLSM) is used to gain the required strength. A PCC layer of 100mm is laid and the foundation reinforcement is placed on it.FOUNDATION AND REINFORCEMENT Based on the subsoil profile and the type of the structures encountered at most of the locations shallow foundations can be adopted. . 5m Pier starter is concreted up to 500mm. pedestal is constructed to a height of 0. After the required reinforcement is placed the concreting for foundation footing is done & M35 grade is used. An earthing rod is provided and is connected to the electrification poles. As per designs the reinforcement of pier is raised. A PVC pipe of 500mm dia is provided in the reinforcement to drain away the rain water and it is connected to the local drain line. . SHUTTERING & REINFORCEMENT FOR PEDASTAL PIER STARTER PEDASTAL PIER STARTER . DRAINAGE PIPE AND EARTHING ROD EARTHING ROD . The shuttering will rest on the manual jacks. and these jacks are rested on the concrete blocks placed around the foundation at same level.SHUTTERING A pre-fabricated shuttering is erected to required height. . With the help of manual jacks the height of the shuttering can be controlled. FORM WORK MANUAL JACK SHUTTERING . and is dumped in the site.ERECTION OF PIERCAP REINFORCEMENT •As per the designs the pier cap reinforcement is done in the casting yard. •By using the crane the pier cap reinforcement is placed on pier reinforcement and is tied to the pier . . layer by layer. Using the needle vibrator the compaction of the concrete is achieved and the walls of the shuttering are tapered with mallet to remove the voids. M45 grade concrete is used.CONCRETING Concreting of the pier is done. .DESHUTTERING AND CURING After a minimum required strength of the concrete is achieved the shuttering is removed. As it is a vertical raised structure curing is achieved by painting a chemical compound. CASTING YARD . .WHAT IS CASTING YARD? An ex-situ place where segments to be elevated between the piers are cast. •So there comes a necessity for a casting yard to speed up the construction work in a safe manner. .Necessity of casting yard •Since casting of segments needs large amounts of space the task of casting segments becomes tedious at site. •Managing the traffic becomes a hectic job. s3.s2. •Each segment is reinforced as per the design drawings in the reinforcement jig.WORK AT CASTING YARD •Various segments such as s1. •After the reinforcement of the segments are done . they are removed from the jig and placed in the mould and concreting is done.s5 are cast.s4A. .s4. •M35-Till Pedestal •M40-For the segments •M45-For the pier .BATCHING PLANT •Various types of grades of concrete are also manufactured at casting yard in a batching plant. 6 2.78 M35 1 M40 1 1.6 Coarse Aggregate 2.9 .DESIGN MIX PROPORTIONS Type Cement Fine Aggregate 1. • Parts of long line mould are 1.
