Efforts are on to complete the crucial road underbridges (RUBs) at the earliest, chief administrate officer (construction) of South Central Railway SK Sharma has said.
Speaking to reporters after inspecting the work here on Saturday, he said the RuB near Rail Nilayam using box pushing technique costs Rs 7.07 crore and is going at a brisk pace. The portion may be completed by June.
“Of the four boxes, two have been pushed and remaining two boxes casting will be completed by this month-end. The cast in situ will be completed by June 2013,” he said.
The RuB has been taken up in view of the heavy flow of traffic between Tarnaka and Sangeet Junction.
According to officials, RUB consists of one vent. The box is crossing five existing running lines and five future non-running lines. Pushing of segments is done with hydraulic jacks.
Sharma said that innovations and best practices have been adopted in box pushing works which will enhance the safety of running trains and expedite the progress of the work.
As the size of the boxes are large, based on the past experience, a second cutting edge has been provided two metres from the top cutting edge and both are interconnected with stiffener plates. This will help in supporting the formation/slope in case of soft soils and emergencies.
The railways have completed their portion of work at the RUB at Alugaddabavi using the box-pushing technique that costs Rs 10.83 crore. The approach roads and drainage will be laid by the GHMC and HMWS&SB.
