Engineering challenge on the Godavari
Megha Engineering & Infrastructures Limited (MEIL) is installing the gates with a hydraulic system for the Polavaram project on the Godavari River in Andhra Pradesh.
Polavaram Project a multi-purpose National project on the Godavari River in the West Godavari District and East Godavari District in Andhra Pradesh.
There are only two projects in the world that have these hydraulic system gates. These are the heaviest gates of its kind in the world. To make this happen by the year-end, the process of placing the Girders on the spillway began on 6 July 2020.
After a traditional pooja was performed, the Girders were placed on the 45 and 46 blocks of the spillway.
After placing the Girders on the spillway, the hydraulic gates will be installed. With this process, the floods will not affect the progress of project work.
The existing reservoirs in the state have the electro-mechanical gates. The operating cost is very high as the iron ropes are to be changed frequently. To overcome this, MEIL is installing cost-effective and advanced hydraulic gates for the Polavaram project.
The Water Resources Department superintendent engineer (SE) Nagireddy supervised the conditions and gave the green signal to place the Girders today.
Polavaram Project, a long-time dream of the residents of the Andhra Pradesh people, is soon becoming a reality, said MEIL on 7 July 2020.
Erection of Girders is a critical work in the Spillway area for which all the preparations have been completed. These Girders will be installed on the Spillway Piers during the first week of July.
“The total length of the Spillway is 1.054-km on which 196 Girders would be erected on the Piers. Each Girder weighs about 62 Tonnes and at present 110 Girders are ready to be erected. All these Girders installation completed within two months.,” said General Manager, MEIL, Mr. A Satish Babu.
If the erection of Girders and road work is completed, then there would be no hindrances for the continuation of the works related to Gap 3 and the Earth cum Rockfill Dam,
Moreover, MEIL is also taking efforts to continue the works even during the flood season.
“MEIL is using heavy machinery like Asia’s first Telebelt-200, which can execute 200 cu m work in one hour. Boom placers are also being deployed to execute concrete works up to 62 metres height. MEIL is also using a hydraulic rig that can dig up to 50 metres depth,” MEIL General Manager Satish Babu said.
The pace of the project lost its momentum in the recent past due to the Coronavirus pandemic, as labourers migrated to their native places. Later MEIL took the initiative of bringing back the labourers by offering them incentives and taking special permissions from the state government.
MEIL, established in 1989, is one of the fastest growing infra companies in India. #construction #dam #dredging #water #tide #AndhraPradesh #Polavaram /fiinews.com
