Hi
I am Rahul Welcome to my youtube channel Civil Notebook.
About this video-
Dosto is video me app logo ko cofferdam ke bare me bolunga.
A cofferdam is a structure that retains water and soil that allows the enclosed area to be pumped out and excavated dry. Cofferdams are commonly used for construction of bridge piers and other support structures built within water. Cofferdams walls are usually formed from sheet piles that are supported by walers and internal braces, and cross braces. Cofferdams are typically dismantled after permanent works are completed.Since cofferdams are usually constructed within water, the sheet piles are installed using preconstructed templates that permit the correct positioning of each sheet pile from a barge.
A cofferdam can in essence be constructed in almost any desirable shape. However, for practical and reasons of economy most cofferdams are either rectangular or circular
1. Braced cofferdams: They are formed from a single wall of sheet piles that is driven into the ground to form a “box” around the excavation.
2. Cellular cofferdams: Cellular cofferdams are used only in those circumstances where the excavation size precludes the use of cross-excavation bracing.
3. Double-walled sheet pile cofferdams: They are cofferdams comprising two parallel rows of sheet piles driven into the ground and connected together by a system of tie rods at one or more levels.
Ummeed Hai Aapko Ye Video Bahut Pasand Aayegi.
Thank you so much.
