This document provides details about the construction of a railway overhead bridge by the U.P. State Bridge Corporation Ltd. It discusses the project details, including specifications of the bridge which is 911.506 meters long with 20 circular piers. It outlines the various steps of construction including surveying, laying reinforcement, shuttering, concreting, and removing shuttering after setting. Suggestions are provided for bridge maintenance and monitoring.

Bridge Bridge is a type of structure that provides passage over obstacles such as valleys, rough terrain or bodies of water by spanning those obstacles with natural or man made materials. Components of a Bridge: a) Deck slab b) Longitudinal girder c) Cross beams d) Bearings e) Joints f) Pier/ Abutment g) Pier cap h) R.E. wall
Types of Bridges
Beam bridge
Cantilever bridge
Suspension bridge
Arch bridge
Truss bridge
Cable-stayed bridge
Introduction: railway over bridge The railway over bridge is a result of collaborated working of Bridge Corporation and Indian Railways. The Railway over bridge is divided as: Rail portion: Its construction is carried out by Indian Railways. Viaduct portion: It lies on both sides of railway portion and is constructed by bridge corporation.
PROJECT DETAILS Department: U.P. State Bridge Corporation Ltd. Lucknow Division: Bareilly Division Site Name: ROB 202 PILIBHIT D.P.M: Er. B.K. Sen A.E: Er. Vijyendra Kumar J.E: Er. Ashish Nirmal Total Length of the Bridge: 911.506 m DURATION of training: 40 DAYS
Continued.. Bridge Type: Beam Bridge Grades of Concrete: a) Foundation: M30 b) Pier and Pier Cap: M35 c) Slab: M40 Wearing coarse: 65 mm Pier: Circular Type 2.5 m diameter solid pier Foundation Type: Open foundation Abutment: RCC Well type Number of Piers: 20 Length of main span: 25.050 m Loading: Two lane of IRC class A loading Bearing Capacity: 16 Ton

Tests carried out before start of construction Material test Sieve analysis Cube test Impact test of aggregates Consistency test of cement Setting time of cement Soil bearing capacity test Plate-load test
Steps in Construction of Bridge 1. Surveying It is the detailed study or inspection, by gathering information through observations, measurements in the field and data analysis in the support of planning, designing, and establishment of property boundaries. Under Surveying we have: Initial site inspection Dimensional tolerances Triangulation Horizontal and Vertical alignments
2. The reinforcement is laid before constructing any structure over which concrete is to be placed. 3. Shuttering Temporary timber, plywood, metal or other material used to provide support to wet concrete mix till it gets strength for self-support. It provides support to horizontal, vertical and inclined surface and also provides support to cast concrete according to required shape and size. Types of shuttering: a) Steel shuttering b) Wooden plank shuttering c) Temporary brick masonry shuttering
Materials required for shuttering a) Bottom (casting bed) b) Beam plate & Cross beam plate c) Tube anchorage d) H.T.S wire (12.5 mm), winding wire e) Nuts & bolts f) Plastic plate g) Wooden block
3. Concreting Concreting is the process of mixing together the various ingredientswater, cement, aggregate, and any additivesto produce concrete. Concrete production is time-sensitive. Once the ingredients are mixed, workers must put the concrete in place before it hardens. In modern usage, most concrete production takes place in a large type of industrial facility called a concrete plant, or often a batch plant. Machines used in concreting: a) Batching plant b) One bag mixer c) Two bag mixer d) Four bag mixer
Bag mixer divided in 3 parts: a) Hooper b) Drum c) Air-bucket 4. After the setting of concrete, the shuttering is removed. Recommended period for removal of shuttering: 48 hours-foundations, columns, beams, walls 7 days-underside of slab up to 4.5 m span 14 days-underside of slab, beam arches above 4.5 m up to 6 m span 21 days-6m to 9 m span 28 days-above 9m span
Suggestions Bridge maintenance consists of a combination of structural health monitoring and testing. This is regulated in country specific engineer standard . A simple test or inspection every two to three years and a major inspection every six to ten years is done. There are several methods used to monitor the stress on large structures like bridges. a) Use of accelerometer. b) Use of Doppler vibrometer.
