Abstract
The invention relates to a cable aisle bridge structure and an installment method thereof and belongs to the technical field of electric equipment. The technology scheme comprises the steps that make cables (1) lay in cable trenches under the ground (30). The cables cross a foundation (2) and a cable protection steel pipe on one side of the road successively. Make the cables lie on a cable supporting arm (14) of a curved bridge frame (12) and then make the cables stretch skyward. The end of the cables(1) which stretch skyward cross an elbow protection pipe(24) and the second pipe successively and then make the cables extend downward. The end of the cables (1) stretch extend downward cross the cable protection steel pipe and the foundation (2) on another side of the road successively again and then stretch into cable trenches under the ground (30). The positives effects of the cable aisle bridge structure and the installment method thereof are that the problem about when the cables pass through the road an operation side of pipe-jacking construction does not exist, or the place which is not appropriate to make the pipe-jacking construction due to the geological problems under the ground or the place where the road is not allowed to excavate can be resolved, the road surface is no need to be destroyed, the traffic is not affected and it is convenient to make construction. The cable aisle bridge structure and installment method thereof has the advantages of being convenient to construct, saving work and labor, short construction period and low cost.
