| 20100307369 | TRAVELWAY STRUCTURE FOR MAGLEV TRANSPORTATION AND A METHOD FOR MANUFACTURING SAME - The present invention provides a travelway structure for maglev transportation comprises: a travelway girder having a concrete girder plate extending from two sides of the travelway girder; a pre-embedded member pre-embedded in the concrete girder plate; and a detachable member installed on the pre-embedded member via a fastener, wherein the pre-embedded member is machinable, and a position for installing the detachable member on the pre-embedded member is formed by a machining process after the travelway girder experiences deformations which lead to errors. A method for manufacturing a travelway structure for maglev transportation is also provided according to the present invention. Specifically, after a period of time, during which the travelway girder experiences most of the deformations caused by pre-stressed tension and gradual contraction and the like, the travelway girder along with the pre-embedded pieces are moved to the machine tools for machining the functional pre-embedded member. Consequently, the installing position of the detachable members can be precisely formed on the pre-embedded members. According to the present invention, the precision of the functional section of the travelway girder in each construction stage can be distributed reasonably so that the difficulty in controlling the precision of the functional section of the integral travelway girder can be overcome. Further, the defects of high cost, heavy weight, and inconvenience in transportation of the conventional travelway girder can be overcome. | 12-09-2010 |
