2. 2. A bridge is a structure built to span physical obstacles such as a body of water, valley, or road, for the purpose of providing passage over the obstacle. There are many different designs that all serve unique purposes and apply to different situations. Designs of bridges vary depending on the function of the bridge, the nature of the terrain where the bridge is constructed and anchored, the material used to make it, and the funds available to build it. When a road needs to extend across a river or valley, a bridge is built to connect the two land masses. Since the average car cannot swim or fly, the bridge makes it possible for automobiles to continue driving from one land mass to another. DEFINATION OF BRIDGE:
3. 3. NAME OF WORK : Constructing Box type slab VRB at Ch 500 m on palaya to shedhi river sub lateral drain near village palaya.
4. 4.  There existing pipe BRB at the chain age 500 meter of near the village of Palaiya.  The existing discharge of drainage system was insufficient to carryout discharge of rain water, so in the rainy season the drainage system was insufficient for discharge of water because sometimes pipes becomes blocked or may be damage. Hence there was frequent demand from local People of Panchayat and Gram Panchayat to remove existing damage pipe type structure and to construct new R.C.C BOX type BRB (Brim River Bridge). Some Problem regarding as stated below:
5. 5. Solution of the problem:  In the solution we are removing the drainage pipes. We construct the box type BRB (Brim River Bridge) instead of using drainage pipe. As per our knowledge:  First of all we will observe the site location of project.  Then we will measure and leveling the site of project.  We will make the plan layout and design of construction.  Than we will estimating the actual cost of project.
6. 6. Achievements after solving the problem:  The problem of blocking of pipe will be solved by using Box type BRB.  The draining of water should be easily discharge from village and farms.  The village people also have a benefit of bridge for migration from one mass to another.
7. 7. DAMAGE PIPES:
8. 8. PLAN OF BRIDGE:
9. 9. FOUNDATION WORK:  The foundation work is done with the depth of height 3.0m.  A length is 3.0m and his was breath 5.55m.
10. 10. PCC WORK:  PCC work has been done the thickness of 0.20cm.  In PCC work a 1:3:4 propotional has been taken.  After PCC work a Bottom slab has been done with the steel work.  A thickness of Bottom slab is 0.30cm above the PCC work.  In a botton slab work a 1:2:4 propotional has been taken.
11. 11.  Now we will considered into our next project that how the profile Wall (Abetment) work has done and the a slab.  And then we will Show you Bridge after its hole construction.  And also we will show you the solution Of a village palaya drain water which can pass easily from a box Type Bridge which in past a drain water should not be pass through easily In that drainage pipe.
