What does bund mean in construction?
A bund is an embankment or wall of brick, stone, concrete or other impervious material, which forms the perimeter and floor of a compound and provides a barrier to retain liquid. Since the bund is the main part of a spill containment system, the whole system (or bunded area) is colloquially referred to as the ‘bund’.
How do you calculate bund wall capacity?
What Capacity Is Required for a Bund?
- Identify the volume of the largest container to be stored within the bund.
- Add 10% to this volume of the largest container, e.g. 207L + 10% = 228L.
- Measure the length x width in cm of the area where the bund is to be located.
- There are 1000 cubic cm in 1 litre.
What is concrete bund wall?
The purpose of a bund wall is to provide a retaining wall around certain storage areas for substances which could potentially pollute the environment. The main job of a concrete bund wall is to stop any of this material from escaping – a pretty important role.
What is the function of a bund?
Bunding, also called a bund wall, is a constructed retaining wall around storage “where potentially polluting substances are handled, processed or stored, for the purposes of containing any unintended escape of material from that area until such time as a remedial action can be taken.”
What is a bund in engineering?
They are a form of enclosure that surrounds drums or tanks, providing emergency containment in the event of a failure. Bunds can help to stop hazardous materials such as flammable or toxic liquids leaking onto the ground or into surface water, protecting the environment from chemical spills.
What is called bund?
Definition of bund (Entry 1 of 2) 1 : an embankment used especially in India to control the flow of water. 2 : an embanked thoroughfare along a river or the sea especially in the Far East.
How do you size a bund?
Bund construction For bulk liquid storage tanks, bunds should include: A bund area big enough to contain 120 per cent of the volume of the largest tank. For flammable liquids, bund capacity should be at least 133 per cent of the net capacity of the largest tank.
What size bund do I need?
Bunds should be sized to hold 110% of the maximum capacity of the largest tank or drum.
What is the difference between bund wall and dyke wall?
Bund wall is a Bunding constructed alongside of storage tanks, where possibly polluting substances are stored and handled. Bund wall also referred as dike wall, but dyke is normally used to describe liquid containing tank facilities which prevent leaks and spillage from tanks and pipes.
How are bunds built?
Contour bunds can either be made of stones or soil (sometimes in variation with crop remains). They are constructed along a contour in order to best slow the water flowing down the slope, which increases the green water pool of the soil and prevents erosion.
What is a bund boundary?
The boundary that separates one land from another is called ‘bund’.
