Description

  The present invention paves each paving machine when a large paving area is divided into plural paving lanes and concrete paving is performed using plural paving machines, such as an airport apron, a runway, a storage, a factory, etc. The present invention relates to a transfer method and a transfer device of a paving machine for transferring from a already-paved lane to a paving start point of another paving lane to be paved.

Conventionally, when pavement areas with a large area such as an airport apron are concretely paved, the pavement area is divided into a plurality of pavement lanes having a width corresponding to the pavement width of the concrete paving machine. When the concrete paving is finished, the next paving lane is opened and the next paving lane is concrete paved, so that every other paving lane is concrete paved, and the ready-made concrete of the paving lane is constructed. It is known that concrete is paved in an unpaved lane when the is solidified (see, for example, Patent Document 1).
By the way, in the concrete paving, every time the concrete paving of one paving lane is completed, the concrete paving machine (paving machine) must be moved to the paving start point of the next paving lane. In this case, since the concrete paving machine that runs on the paving rail installed along the paving lane cannot run on the road surface, the paving is finished at the paving end point of one paving lane. The paving machine is lifted by a mobile crane, removed from the one paving lane, moved to the paving start point of the next paving lane, and installed on the paving rail of the paving lane. If the next paving lane is quite far away, as described in Patent Document 2, the paving machine is left as it is or once disassembled and loaded into a transport vehicle with a large crane and transported to the vicinity of the paving start point. Therefore, using the crane, the paving machine is installed as it is or on the guide rail of the paving start point after reassembly.

These are used, and concrete pavement is performed while traveling from the pavement start point a to the pavement end point b in the above order.

Next, in the concrete paving, for example, when paving in one paving lane s3 is completed, a method of transferring each paving machine M1 to M5 to the next paving lane s5 will be described. Guide rails R1 and R1 similar to a pair of railroad rails are installed at right angles to the paving lanes s1 to sn (guide rails R2 and R2) at positions close to the paving ending points of the paving lanes s1 to sn. It is assumed that the transfer device 1 of the paving machine is prepared to run on R1 and R1.
