Ensuring security and defense of the frontier region of Mekong Delta provinces and will be 222tcn basis for research for development and replicate 249-9 model of multi-modal transport.

The bridge is only used for motorbike and waking. Results of hydrology calculation are shown in detail in separate reports, here only a summary of water level data used in design works 429-98 follows: Each section is 3. If we buy it, we must transport km from factory to the site. The biggest monthly absolute humidity is about Thien Ho Bridge with 2 lans and HL93 live load.

Total losses was about 4, billion, in which inundated area was up to 2. Because bridge is outside urban area, now not design lighting, just set available positions on bridge.

Wooden deck slab, 1. Thickness changes from 1. Those bridges in area of 03 249-8 Calculation sheets – Volume 4: Girder length is 18m and 15m, 14m, it is product of factory and convenient for construction.

According to the Decision No. Projects of 13 bridge is part of Component B – Phase I of project, aiming to upgrade and return the existing bridges crossing the Waterway Corridor No. The upgrading of roads, waterways in the region will bring enormous benefits, contribute to poverty alleviation, socio-economic 249-89 and create conditions for inter-connection in the regions, reducing rate of traffic accidents on roads and waterways.

Survey results show that traces of floods history in year were not faded. The clearance of Navigation is 6m height for all bridges cross waterway corridor No. Use product 22tvn Co Khi An Giang factory, transport to the site by waterway with the distance is Two piers of middle span are shape steel, the other piers are wood.

So, we must build a new bridge, remove the existing bridge complete 249–98 dredge the canal. The selected span layout is to meet and satisfy the following requirements: We have a comparison for two options: Railing is shape steel has been rusted heavy.

This issue has been mention in letter No. Every year, this area is often flooded for several months in the flood season. From comparison of 2 options, Consultant chooses the option of Bailey for middle span because it is cheaper. The physical-mechanical characteristics are as following: According to measurement results in Cao Lanh station, the total sunshine hours are In terms of flood peak, flood duration, total volume and risk level, the flood of year was the biggest flood during recent 75 years.

Due to the special nature of flood risk in yearfloods in year is selected as standards by the Ministry of Agriculture and Rural Development, Ministry of Transport when calculating for testing, calculating for design for irrigation and transportation works in Mekong delta provinces. This design report is made for My An Bridge. When designing this route, should ensure conformity with general development 22tccn and not obstruct the flow. Bridge area is affected by tidal regimes of sea and internal rain.

According to the Terms of Reference and other documents: So we need soft soil treatment or add more span, more piers, then it can make the cost increase.

Other norms and standards No. Assembled at 24-98 site. Pile cap, body and capping are cast in place reinforced concrete 30MPa. The biggest monthly average absolute humidity is about Measurements results of average monthly rainfall and largest rainfall are presented in the table below: Monthly average absolute humidity is presented in the table below.

Use precast girders from Binh Minh factory, transport to the site by waterway with the distance is Double bituminous surface treatment with 2 layers standard 3. So we need 2 lanes for span next to the middle span.

Truss type bailey 4. The flood impact on this area is not large. The distance between new bridge and the existing bridge is about 75m upstream direction to Tien Giang as Document No.

The elevation system is national system.
