Flyover Construction with Precast Piers in India
The construction industry has witnessed many new experiments in India, and the growth is always upward since the ace engineers rightly use their knowledge for the betterment of the country. India has adopted many a strategy for developing their urban construction. The use of precast piers for constructing flyovers is considered to be a new strategy that opens up a new way of the construction.
Such construction of flyovers does not disturb a regular traffic flow on existing roads and allows the constructor to perform their work without any hindrances. The inconvenience caused by construction work can be avoided by this type of construction.
The construction process of flyovers needs cranes to erect the precast, massive structure to the work site without chocking the traffic flow. The Indian Society of Trenchless Technology (INDSTT) has brought a trenchless pipe laying technology that boosts an unhindered construction in the urban areas.
Planning and designing process also get computerized instead of man-handled that provides an accurate mapping of a project. The concept of constructing flyovers with precast piers is increasing with time. In India, many places have already adopted the technique as a part of their urban construction project.
J.J Hospital Flyover in Mumbai is a well-known name that is constructed using piers pipes technology. The flyover stands an example of an engineering performance and a superlative architectural design. The engineers handle more than difficult challenges to construct the bridge as per their plan. The greatest among all was constructing a pier formwork from 80 tonne single pour concrete. The pier height was 8.5 m. the flaringshape was planned for the bridge with unbroken finish and smooth grooved on the cast structure of the pier.
Bajaj was the name behind designing and constructing the flyover which made open to the public in 2002. The company with its in-house expertise and technology met the requirement stated by UK based consultant. The unique flyover was structured with 400 elements in two halves. The surface was lined with specially formed rubber to add the designed surface finish. Hydraulic systems helped to form the structure with accuracy and high efficiency. The time taken for assembling each mould casting was 4 hours and striking time was 2 hours for per pier casting. The piers of the bridge are as many as 70 and they were cast by a single construction system.
The engineering of such flyover is highly appreciated, especially in the developing countries like India. The flyovers are constructed worldwide using this technique. The benefits have already been felt in the construction industry, and in socio-economical perspective, this construction goes a long way.
