00:00The Polavaram Project has decided that it is impossible to completely stop the seepage in the Pradhana Dam area.
00:08To do work in the Pradhana Dam area, it has decided to send some of the water out through gravity.
00:14It has decided that the only way is to remove the remaining water through pumps.
00:18To do work in the Pradhana Dam area, it has decided that the seepage water should be allowed only to a depth of 17 meters.
00:28To do work in the Pradhana Dam area, it has decided to send some of the water out through gravity.
00:32It has given clarity on some of the indicators.
00:35To determine whether the seepage is happening from this dam or not, it has suggested to conduct many more tests.
00:43It has also explained how to drill boreholes and how to conduct tests.
00:49It has also suggested to test whether seepage is present or not by placing a few holes in the junction and some clay cores.
00:58It has also suggested to place fissometers in some places to identify seepage.
01:04It has also suggested to test whether seepage is present or not by placing a few holes in the junction and some clay cores.
01:09If seepage is found to be present from these structures, treatment methods will be provided accordingly.
01:15It has also suggested to send these tests to foreign companies.
01:18The dam area has been affected by heavy rains in 2020.
01:23The land and the environment have changed.
01:25To build the dam, it has decided to fill the boreholes with sand and increase the density.
01:32There are difficulties in increasing the sand density in some places.
01:37To treat the sand up to 20 meters deep, it has suggested to conduct multichannel analysis of seismic rays in those areas.
01:50To increase the sand density in those areas, it has suggested whether the land and the environment have changed or not.
02:00If the sand density does not increase, it can be densified in some places.
02:05It has suggested to build the dam in those areas.
02:09In the Polavaram project, the guide bond was broken in Gatham.
02:12Due to the work carried out in two different seasons, the sand and clay cores have reached the stone columns and the dam has been built.
02:20In the same period, work has been done on the construction of Gap 1 Pradhana Dam.
02:24Some of those works have been carried out.
02:25In this case, in Gap 1 Pradhana Dam, it has suggested to conduct tests to determine the strength of the construction in the stone columns.
02:32It has suggested to drill holes in the stone columns and send water.
02:36In this way, it has suggested to conduct permeability tests.
02:39It has suggested to determine the strength of the stone columns and send water.
02:44After conducting these tests, it has suggested to send the results to Nipuniluprundan.
02:48In the area where the Pradhana Dam is being built, there are some sand dunes.
02:52Due to the floods here, new sand dunes are formed from time to time.
02:55In that area, it has suggested to excavate the sand dunes.
02:59It has suggested to conduct tests to determine whether there are sand dunes between the sand dunes.
03:05Along with the work of Pradhana Rathi Mud Dam, their opinions about the diaphragm are valid in Tudhini Vedika.
