Vetiver System: The Soil Healer

Introduction:

Soil disintegration is one of the biggest environmental issues confronting the earth today, and the North-Eastern district of India, with substantial rainfall, is especially affected. Vetiver Grass system is a well-established arrangement for the assurance of soil slants from disintegration. It is utilized for this reason in more than 100 nations all through Asia, Africa, and America, where it is an easy, environmentally sustainable, and community-friendly arrangement.

 Why this method?

Conventional hard engineering interventions that mean to legitimately diminish disintegration are exorbitant and ecologically harmful. Thus vetiver, a C4 plant, has held up as a fantastic green solution to this circumstance.

Vetiver, a plant elevated to preserve soil and water for agribusiness by the World Bank, advanced in the last part of the 1990s has turned into a significant soil bioengineering tool. The foundations of vetiver develop quickly and can accomplish a profundity of 3m in one year. Vetiver can fill in unfavourable soil conditions and outrageous climatic conditions. The vetiver grass arrangement has become a field tried, affordable, environment, and community-friendly, and manageable framework for disintegration control on slants and in drainage networks.

Effect of vetiver grass on erosion control:

The event of disintegration involves the following three phenomena:

1. Sub airborne arrangement:- 
• Vetiver canopy scatters raindrop energy and reduces wind disintegration.
• Stems lessen run-off erosion
2. Molecule entrainment:- 
• Submerged overhang and stems diminish close bank stream speed, damps disturbance, and scatters wave energy.
• The root framework truly restraints soil molecules.
3. Mass collapse:- 
• The root framework diminishes overabundance pore pressures, and impede pushing off totals of soil.

Slope stability and root strength:


Shallow slips of 1-1.5 m, involve most of the issues particularly in locales with prolonged and high precipitation. To handle this issue, the vetiver is used to reinforce the surficial 1-1.5 m layer that is vulnerable to slippage.
When vetiver roots associate with the soil in which it is grown, another composite material with roots of high rigidity is formed. Vetiver roots strengthen soil by the move of shear pressure in the soil grid to tensile incorporations. At the point when the thick and huge root networks act as one, they take after the conduct of soil nails ordinarily utilized in structural engineering works.

Conclusion:

The vetiver plant fits well in the high precipitation Assamese atmosphere and the red sandy dirt of the slopes and sandy waterway bank. Vetiver can play a significant part in the feasible administration of foundation by controlling the disintegration of road batters, bridge approaches, high dikes, streets without cross seepage, mountain streets, and so forth in a prudent and climate neighbourly way. Vetiver ingests about 30% more CO2 from the environment. In this way, it is an extraordinary device for the decrease of an Earth-wide temperature boost and an undertaking of the road designing society to go for green roads.

CYCLONE RESISTANT BUILDING CONSTRUCTION Cyclones have been an inescapable situation in India, especially in the eastern states of Odisha, West Bengal, and Andhra Pradesh. This calls for the construction of cyclone-resistant buildings in cyclone-prone areas to avoid loss of life and property. Low-lying coast areas, river floodplains, and sea-shore areas are highly vulnerable to cyclones. Certain settlement pattern even causes "funnel effect" which results in greater damage. While it's a common belief that heavier buildings are safer, in reality, a well built and engineered house provides better safety. Minimum standards for the design, construction, and performance of buildings to withstand extreme climate-related natural hazard events depending upon their locations should be set. We know cyclones are beyond human control but measures can be taken to reduce the loss of lives like evacuating people to safe areas, quick recovery of important fa...

    Source: Wikipedia     Central Vista Redevelopment Project  refers to the ongoing  redevelopment  to revamp the Central Vista, India's central administrative area located near  Raisina  Hill, New Delhi . The area houses India's government and parliamentary offices and has  been  described as the "power corridor" of the country. The project seeks to improve infrastructure for the Government of India, including retrofitting and refurbishing some heritage buildings to make them functional and safe.        Source: The Hindu   The Central Vista Redevelopment Project was launched in 2019 .   The project includes converting North and South Blocks into public museums while creating an ensemble of new secretariat buildings to house all ministries, relocating the Vice President and the Prime Minister's offices  and residences near the North and South Blocks, and revamping the 3 km (1.9 mi) long  Rajpath  between  Rashtrapati...

Demolition of Building Structures

Image
Demolition of a building is the process of dismantling or destroying a structure after its life of serviceability by pre-planned and controlled methods. It is the science and engineering in safely and efficiently tearing down buildings and other artificial structures . The tallest planned demolition of a building was the 47-storey Singer Building in New York City , built-in 1908 and torn down in 1967–1968 to be replaced by One Liberty Plaza Building Demolition methods: There are two types of demolition methods used for buildings and structures, Non-explosive demolition and Explosive demolition. In the non-explosive method, demolition of a structure is done with some equipment, without the use of any explosive. In contrast, in the explosive method, demolition is done with the help of bombs and explosives. Building Demolition Process: Different steps are involved in the process of demolition of building structures. They are: 1. Surveying 2. Removal of hazardous materials 3...
