INTERCHANGE OVERBRIDGE APPROACH PART STRUCTURE AND ITS CONSTRUCTION METHOD

Japanese Patent JP3895339

B2

PROBLEM TO BE SOLVED: To solve the problems that an interchange overbridge requires a longer construction period and high construction cost when adopting an approach part consisting of a land elevation and side walls on both sides, where lane closure is a must as sideways are used for the construction work to cause traffic jam, and requires a larger foundation structure for bridge piers and longer construction period and high construction cost when adopting the approach part consisting of road floor slabs and bridge piers.
SOLUTION: An approach part structure 3 for the interchange overbridge comprises a pair of reinforced concrete pier wall structure 6 continuously extending to the axial direction of a road and a road floor slab structure 8 provided on the pier wall structure 6. The road floor slab structure 8 consists of a plurality of precast floor slabs 10 each having a preset length in the axial direction of the road, connection means 11 for connecting the plurality of precast floor slabs 10 arranged side by side in the axial direction of the road together, and anchor members 12 for positioning the precast floor slabs 10 at the upper end of the pier wall structure 6 and connecting them together.
