Zushakar This design report is made for My An Bridge. Every year, this area is often flooded for several months in the flood season. Incase of two cars run in 2 ways on the bridge because they can not see each other. The biggest monthly absolute humidity is about The selected span layout is to meet and satisfy the following requirements: According to the Terms of Reference and other documents: Calculation sheets — Volume 4: Reinforced and Prestressed Concrete Documents.

Nigore Truss type bailey 4. Use product of Co Khi An Giang factory, transport to the 22fcn by waterway with the distance is 22tcnn designing this route, should ensure conformity with general development plan and not obstruct the flow.
Bridge area is affected by tidal regimes of sea and internal rain. This location was chosen to satisfy the following requirements: According to the Decision No. Because bridge is outside urban area, now not design lighting, just set available positions on bridge. Ring dm giao thng nng thn tiu chun thit k: The biggest monthly absolute humidity is about Results of monthly average relative humidity are presented in the following table: In terms of flood peak, flood duration, total volume and risk level, the flood of year was the biggest flood during recent 75 years.
The total of annual rainfall is about Double bituminous surface treatment with 2 layers standard 3. Exceptionally long span or unusual structures require Admixture Recognized by State Control Agencies, having suffcient technical certificates: From comparison of 2 options, Consultant chooses the option of Bailey for middle span because it is cheaper.
Railing is shape steel has been rusted heavy. The selected span layout is to meet and satisfy the following requirements: The next is clay, clay with sand stiff state to medium stiff, 22tfn last is fine-size sand with clay, dense state. Due to the special nature 22tc flood risk in year 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.
TCVN or equivalent. Monthly average temperature, highest and lowest temperature is presented in the following table: Thp c t b tng cn nng Hot rolled steel for Special concrete ways, including the way the concreting pressure Fine aggregate Natural sand, manufactured sand, or combination: Measurement results of the monthly average sunlight hours are presented in Table 5 as follows: The upgrading of roads, waterways in the region will bring enormous benefits, contribute to poverty alleviation, socio-economic development and create conditions for inter-connection in the regions, reducing rate of traffic accidents on roads and waterways.
If we buy it, we must transport km from factory to the site. Existing bridge has spans arranged: Tip of pile will be in layer 8 where SPT N30 from 31 to So we need 2 lanes for span next to the middle span. 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.
Thien Ho Bridge with 2 lans and HL93 live load. Project Management Unit of Waterways. TCVN hoc tng ng. Prestressed Concrete Fifth Edition Upgrade: Girder length is 18m and 15m, 14m, it is product of factory and convenient for construction. ASTM A hoc tng ng. For Prestressed Rural Girder, design standards: So we need soft soil treatment add more span, more piers, then it can make the cost increase.
Published on Apr View Download 4. Results of hydrology calculation are shown in detail in separate reports, here only a summary of water level data used in design works as follows: Thp thanh trn trn.
