PROJECT: INVESTMENT IN CONSTRUCTING TRI BINH ROAD – DUNG QUOC PORT( KM 0+00-KM 8+743.72).

CONSTRUCTION: Tra Bong Bridge Km 5+293.32

Owner: Management Board of Infrastructure Investment Projects.

Contractor: Phuc Loc joint stock company

PROJECT INTRODUCTION

 -  Tra Bong Bridge crosses the Tra Bong River in Binh Chanh Commune - Binh Son District - Quang Ngai Province. The construction area is 3.0km away from the sea.

    Total length of bridge L= 668.10m

    Main technical parameters:

       - Construction scale: Permanent structure with reinforced concrete and prestressed reinforced concrete.

       - Flood frequency design : P=1%

       - Boat-through size: Boat-through river level IV, BxH= 40x6 m.

       - Load test design: Design load HL-93, group of three people kN/m2.

       - Earthquake level: Level 6 (MSK-64 system), accelerator coefficient of foundation A=0.052.

       - Bridge size: B= 2 + 15.625 + 1.5 = 19.125m.

       - Speed design: V= 80 km/h.
