Lasers: A Revolution in Highway Engineerin

Introduction: -

The advancement of new technology has been taking place since the beginning of human history. However, it has been exceptionally fast and changing the engineering world in recent decades at a record pace. One such technology, lasers, is used in highway engineering for various purposes like road profiling, pavement surface redirection, bridge deflection, speed checkers, accident spot analysis etc. These laser techniques have greater accuracy as everything is automated with faster data collection and less human involvement.



Applications: -

Road Profiling



The profile of a path is calculated around some in-existent line or point which is permanent. Besides the rutting and the other issues, the profile of a path which is taken along a lateral line shows over the altitude and crown of the route outline. The longitudinal profile displays the ruggedness, hardness, and grade of the material.

It is used for tracking the status of a pavement management system road network (PMS) network, for determining the existence of built or separated environments.

Bridge Deflection




Bridge Deformation is instigated by the movements in the land conditions, including the overloading. Measuring the deformation is necessary for knowing the bridge's safety, for ensuring its healthy usage. The deflection measuring device is composed of the laser emitter, laser receiver and upper computer. The laser beam will provide long-term reliability and high precision of positioning to guarantee the spot centre's precise positioning.

Speed Checkers

Lasers have been utilized for monitoring the vehicle's speed to limit risky street mishaps. The street speed checker is helpful for the traffic police, particularly against speed limit violators, as it offers the digital monitor as well as the buzzing sound or warning for identifying the vehicle speed if the vehicle speed reaches the limit required.

Advantages

  • The laser-based framework can be utilized for measuring the road profile and redirection precisely while travelling at normal speed.
  • The laser-based framework likewise brings about the fast estimation and snappy assortment of the information.
  • It is used for assessing the different territories from the single instrument position.
  • It doesn't need any setup or breaks down.
  • It is the framework that can be fitted on any vehicle needed by the customer.
  • The laser-based framework can work at a speed of 105 km/hr.
  • It is the system that collects data in real-time as it traverses the pavement's surface.
  • It discards the prerequisite for lane closure or traffic control while testing.

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...

Central Vista Project: Transforming the Political Face of India, the Civil Way

Image
    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...
