This is an invention relating to highways drainage system. During the author’s practice as a highway Structural Engineer in NHAI’s projects and world bank projects, he has noticed extreme delays in the construction of highway drainage work. Highway Drainage is very important and sometimes cost as much as 10%of project cost depending upon the place. Without proper drainage highway pavement and sub grade detoriates very fast. The Drainage sidewall also acts like a retaining wall in urban areas thus preventing movement of soil and water entering from outside. But drainage construction by cast- in situ method involves much delay (sometimes even 5 years in congested areas and due to point to point variation of cross section of drainage structures) and hence there is a need for modification in construction methodology and novel methods of design and construction. This invention speeds up the major side drainage construction (RCC Drainage of more than 1.5m×1.5m size) so that time and cost delays are avoided.It will be a boon for all NHAI and BOT projects if this method is adopted.
