Docks

Docks Meaning and Conceptual Learning Docks Overview Docks are enclosed area used for berthing of ship to keep them at uniform level for loading and unloading of cargo or renovation. They are classified as : 1. Graving or dry dock 2. Floating dock 3. Marine Railways 4. Liff Docks • Graving or Dry Docks : It is a long excavated chamber which is having sidewalls, semicircular end walls, and floor. As it is having two ends, the open end is provided with a gate and acts as an entrance to the clock. The side walls formed with the series of steps known as altar courses to receive the ends of shores which support the vessel in a vertical position while being docked and such altar courses of granite to withstand heavy wear. Culvert provides for filling and emptying the dock. • Size of Dock :  Size depends on the size of largest ship it has to be a dry dock. Dry dock to handle modern big ships having 1000ft. in length, with an entrance width of 60ft. to 100ft. The ratio of length to breadth of

Entrance Locks

Entrance Locks of Harbors and Docks Entrance Locks are those which give access to docks Components of Entrance Locks 1) Chamber: which is enclosed by quays wall on each side and bottom is paved by inverted arch flooring which resists upward water pressure when lock level is low 2) The gates closing entrance constructed of wood or iron of heavy design to withstand water pressure 3) The sill is raised above the gate floor by 2 foot 4) Sluice way   provided in side walls for filling and emptying locks Dimensions of Entrance and Locks It main factor are width, size, and displacement of the longest vessels. Modern locks have width vary from 80 foot and above and depth 25 foot to 40 foot and length of 800 foot and over. Construction of Entrance and Locks Materials   generally used are: 1)Wood 2)Iron Wooden Gates It consists of a horizontal beam that is spaced closer at the bottom to resist water pressure and joined together by heel post in such a way that two extreme ends meet at middle.

PARTIAL REPLACEMENT OF CEMENT WITH SOYABEAN HUSK ASH AND GGBFS

Upgrade yourself with replacer of cement by Soyabean husk ash and ground granulated blast furnace slag (GGBFS) ABSTRACT The demand for concrete as a material of construction has increased as the demand for infrastructure development has also increased, especially in countries such as China and India. Concrete is key material used in various types of construction from flooring of a hut to a multi storey high rise building. Concrete is one of the versatile heterogeneous material. Reinforced concrete is one of the most popular material used for construction in the world. With the advent of concrete civil engineering has touched highest peak of technology. It is the material of choice where strength, durability, impermeability, fire resistance and abrasion resistance are required .The properties of concrete mainly depend on constituents used in concrete making. The study focuses on production of Soyabean Husk which is being produced in a farm under threshing process so such material can b

Drainage in Tunnel

Load the mind with new topic of tunnel engineering which is  Drainage of Tunnel                         BASICS ABOUT DRAINAGE IN TUNNEL In a tunnel water comes from shafts and portal which is being dug in order to achieve the alignment of tunnel, water which is being used during washing  holes of drill and progressing the tunnel during the time of construction,The water obtained from the first source cannot be easily determined and water obtained from the second cause requires analysis and investigation and can be prevented by RCC bulkhead. Exploding charge may open up a ground water source unexpectedly omitting large quantity of water into the tunnel. Such sudden shot of water give rise to conditions  An underground pocket or lake has been trapped. An underground flow with an inexhaustible source such as river or  lake has been trapped The progress of tunneling work and the maintenance of tunnel drainage after its construction primarily depends on good drainage of tunnel.If the drai

Vision Zero Sweden Traffic Control Policy

FUTURE OF ROAD SAFETY IN INDIA :A CASE STUDY  TO IMPLEMENT ‘VISION ZERO’ POLICY ABSTRACT The present report provides a comprehensive review of road safety scenario in India from a public health perspective. Data sources for the review include published and unpublished reports from National Crime Records Bureau (2016), Ministry of Road Transport and Highways (2016) as well as global reports and independent research studies / reports/ unpublished documents. The report focusses on Road Traffic Injuries, deaths, disabilities, risk factors, injury patterns and distributions, as well as the current Indian response to this burgeoning epidemic. This summary report in conjunction with the detailed report entitled “Advancing Road Safety in India-- implementation is the key “ and “Advancing Road Safety in India-- facts and figures” provides in-depth information on all aspects of road safety and the current road safety initiatives from the Indian region. These reports are aimed at policy makers fr
