A culvert may act as a bridge for traffic to pass on it. They are typically found in a natural flow of water and serves the purpose of a bridge or a current flow controller. Culverts are available in many and shape like round, elliptical, flat-bottomed, pear-shaped, and box-like constructions. Culverts are by their load and water flow capacities, lifespan and installation of bedding and backfill.

The type is based on a number of factors including hydraulic, upstream elevation, and roadway height and other conditions. Following are the different types of Culvert :. Pipe culverts are the most common types of culverts due to competitive price and easy installation. They are found in different shapes such as circular, elliptical and pipe arch. Generally, their shapes depend on site conditions and constraints. Pipe culverts on a small scale represent normal pipes like concrete pipes.

Arch culverts are suitable for large waterway opening where fishes can be provided with a greater hydraulic advantage. Moreover, they provide low clearance and are definitely, much artistic. Pipe arches are particularly useful for sites where headroom is limited and also have a hydraulic advantage at low flows. The most challenging part in constructing a box culvert is that dry surface is needed for installing it. However, due to the strength of the concrete floor, water direction can be changed when a large amount of water is expected.

This feature makes box culverts, one of the most commonly found types of the culvert. An arch culvert is made up of metal, stone masonry, concrete, RCC etc. Construction does not take a lot of time and unlike box culvert, water diversion is not necessary, as it can be installed without disturbing the water current.

Thus, it can be termed as a Low Profile Culvert. This type of culvert maintains the natural integrity of the wash bed.The main purpose of constructing culvert structure is to provide passage over the obstruction. It is embedded in the soil on both sides. Slab culverts can replace box culverts if no artificial flooring is necessary. Slab culverts do not have bottom slabs, therefore, the natural flow of water is maintained and natural bottom substrate remains intact. While constructing the slab culvert, a series of slabs are laid to form the bridge-like structure.

After that, a pavement surface is placed on top to serve the purpose as the road. ASTM C design code is followed to design the slab culvert. Please note that the information in Civiltoday. The information provided should not be used as a substitute for professional services.

Swaminathan, Professor of the Civil Engineering Department for all his help and guidance. I would like to express my deepest sense of respect and indebtedness to my Internship Supervisor, Mr.

Sadasivam V. Nisha K. I owe my wholehearted thanks to Mr. Lingarajan K. I also thank the entire staff of the company for their cooperation and assistance during the course of my project. I hope that I can build upon the experience and knowledge that I have gained and make a valuable contribution towards this industry in the coming future.

Earth Pressure including live load surcharge 8. Temperature Effect 9. Seismic Forces 1. Should also be checked for Class A Loading. Longitudinal moments are calculated in the same way by multiplying reactions with the longitudinal eccentricity which is the distance between the centerline of pier and bearing.

The reaction on each bearing due to girder, diaphragm and deck slab and due to Super- imposed Dead Load, SIDL wearing coat and crash barrier is found out separately. A point worth noting is that STAAD requires the distance to the centerline of the outermost wheel away from the origin along the transverse direction, while during manual calculation of transverse moments the eccentricity of the center of gravity from the centerline of the carriage-way is used. As per IRC table 2, for a 3 lane, 12m wide carriage-way, 2 critical load combinations are possible.

The reactions on each bearing is noted down from the STAAD model for design of pier cap and for the calculation of transverse and longitudinal moments.

A small bridge having total length of 6 m or less than 6 m between the faces of abutments is known as culvert. Culvert is a permanent drainage structure mainly constructed to carry roadway or railway track over small streams or channels.

These arches can be easily and cheaply constructed. The culvert, having its superstructure consisting of RCC slab which carries the bridge floor, is known as slab culvert. In this type of culvert, the RCC slab of suitable thickness is provided as simply supported over abutments and piers which are constructed of any suitable type of masonry. Slab culverts are suitable where the bed of the canal or stream is sufficiently firm.

The culvert which consists of one or more pipes placed side by side over a concrete base below the embankment of a roadway or railway track is known as pipe culvert.

In pipe culverts, generally, more than one pipe, of diameter not less than 30 cm is used. As far as possible the gradient of the pipe should not be less than 1 in Pipe culverts are suitable where the flow of water in the stream is very small. The culvert consisting of one or more numbers of rectangular or square openings, having their floor and top slabs constructed monolithically with abutments and pier, is known as box culvert.

Box culvert is usually constructed of precast RCC slabs. Small span box culverts may be constructed of stone slabs, supported on masonry abutments, with brick or stone flooring.We want the information on this website to be the best it can be and we know we can't do this without you.
