Broken Ranipokhari bridge is not repairable, new one will be built
After the 57-year-old motor bridge between Rishikesh and Dehradun at Rani Pokhari was damaged by floods, the only option left before the Public Works Department is to construct a new bridge
After the 57-year-old motor bridge between Rishikesh and Dehradun at Rani Pokhari was damaged by floods, the only option left before the Public Works Department now is to construct a new bridge in its place. Chief Engineer, Public Works Department, Hari Om Sharma, after inspecting the bridge said that about Rs 1411.18 lakh was approved from the Central Road Fund for the new bridge here. The old bridge is no longer repairable therefore, a new bridge will be built in its place, on which the final decision has to be taken by the government.
In the year 1964, a two-lane bridge was constructed by the Public Works Department at Ranipokhari between Rishikesh and Dehradun. This 57 year old bridge was built on an open foundation technique. On Friday afternoon, both the pillars of the bridge were damaged due to floods in the Jakhan river. Due to this the bridge was broken in two places. Chief Engineer of Public Works Department Hari Om Sharma inspected the damaged bridge.
He said that at the beginning of the bridge in the direction of Rishikesh, four pillars were damaged, due to which a part of the bridge was broken. After this, two panels of the bridge were damaged, causing a part of the bridge to break. He said that two panels in the center of the bridge are also likely to be damaged due to excessive pressure. He told that in the year 2020, Rs 1411.18 lakh has been approved from the Central Road Fund for another new bridge here. In place of this bridge, a new bridge can be built with the said amount. The department will soon send a proposal in this regard to the government.
The Chief Engineer said that for immediate arrangements, we are waiting for the water flow in the river to slow down. After this, a causeway will be made by putting cement pipes here. Bhogpur Thano Road is also being considered for use as an alternate route. According to Chief Engineer Hari Om Sharma, prima facie the main reason for the damage to the bridge is that the water pressure of the river was more towards the shore. Due to the increase in water pressure at one place, the foundation of the bridge became hollow and the bridge collapsed.
This is Open Foundation Technique
57 years ago, when the bridge was built at Ranipokhari over the Jakhan river ,it was constructed by making the base on the foundation of the open foundation i.e. the upper level of the ground. Chief Engineer Hari Om Sharma said that the depth of the foundation is decided according to the water flow of the river. Generally, the foundation of such a bridge is laid up to a depth of four meters. In the olden times, the construction of buildings was also done on this technology. Now most of the new bridges in rivers with high water pressure are being built on well foundation technology. The water level of Ganga in Munikireti is constant. For this reason, the bridge was constructed here after pouring the well foundation to a depth of 12 meters. Now whenever a new bridge will be built in Rani Pokhari, well foundation technology will be used instead of open foundation.
