HIGH LEVEL BRIDGE ACROSSKALISIND RIVER

NEED FOR CONSTRUCTION

To improve traffic management system.

To reduce hindrance to traffic flow.

By increase the volume of road, chances of accidents get reduced hence it will act as a life saving drug.

Providing road illumination required.

TEST PERFORMED AT SITE AND SITE LABORATORY

(a) At site of work:- Slump test for measurement of workability of concrete. (b) At site laboratory:- (i) Compressive strength test of concrete . (ii) Grading of aggregates-Sieve Analysis Test.

SLUMP TEST FOR WORKABILITY OF CONCRETE

Most common method for measuring the consistency & uniformity of concrete. APPARATUS REQUIRED FOR TEST:• Cast iron mould in the form of frustum of cone having internal dimension:- Bottom diameter : 20cm Top diameter : 10cm Height : 30cm• Tamping Rod of 16mm diameter.

Foundation For piers and abutments • Types of bridge foundations- 1. Open foundation2. Well foundation3. Block foundation

Open foundation & Block foundation are come under shallow foundations . well foundation are come under deep foundations.

Open foundation

• Types of open foundation-Isolated , combined, and strip footings.Raft foundations.

CURING OF OPEN FOUNDATION

WELL FOUNDATION

Pre-Stressing Pre-stress

concrete is the one in which there have been introduced internal stresses of such a magnitude and distribution that the stresses resulting from given external loading counteracted to a desired degree.

Pre-Stressing

SUBSTRUCTURE PIERS & ABUTMENTS

Piers and abutments are the vertical structures supporting deck,girders,bearings providing for transmitting their load along with live load coming over bridge to the bed/earth through foundation.
