Description

Concrete track construction method that can be used suitably for a rapid improvement of ballast track, and concrete slab support device and railway building device for the same}

The present invention relates to a concrete track construction method using a precast concrete slab and a concrete slab support device and a railroad laying device therefor.

In general, the gravel track has a structure in which the load of the train is distributed and transmitted to the lower roadbed through rails, fasteners, sleepers, and gravel, but the initial construction cost is cheaper than the concrete track and it is easy to repair when the track is twisted, but the train is operated. As a result, vibrations occur, and gravel breaks and changes in position cause continuous settlement, resulting in high maintenance costs.

In addition, the gravel track is negative in terms of environment, such as dust and late-night noise pollution caused by night maintenance when the train is operating after construction. There is also a problem that the rail and train vehicles are damaged due to the splashing of gravel debris, which causes out-of-track repair costs.

It is reasonable to significantly reduce the track maintenance work by basically replacing the gravel track with a concrete track to improve the track structure for the old gravel track, but in poor working environments (lack of work time, lack of work space, lack of gravel thickness, some places) It is difficult to improve the gravel track with existing track improvement technology due to the impossibility of gravel change work).

The pavement track method, which is one of the technologies to improve the existing gravel track that is currently operating a train, into a concrete track, is a method of removing gravel from the gravel track and injecting cement mortar to make it concrete, from the end of train operation to the start of the next day. It has a problem that it is difficult to construct for a short time.

In the case of KORAIL, the track design for the Gwacheon Line between Geumjeong and Namtaeryeong was improved in 2010 to secure track stability, such as securing the safety of trains and providing maintenance efficiency due to the deterioration of the function of the track facility (21 km) and aging. The project is in progress, and B2S Track (Ballasted Track To Slab Track) was applied to the detailed design as an improvement method, but the improvement project was promoted. Due to the inability to accept site conditions and support for construction equipment for developers, only 1.8km section improvement was carried out between 2013 and 2016.

The B2S system conducted at Seoul Metro has the technology of improving 5~10m within 4 hours of the train cutoff time, but there is no technology for rapid improvement, and the B2S construction equipment is expensive and there is only one in Korea, so there is a limit to the field application.

In order to find a solution to this, efforts have been made to improve the gravel track to a concrete track, but in the process of improving it, a lot of costs are incurred, and even abroad, the rapid construction technology to improve the existing service line to a concrete track is not secured. .

An object of the present invention is to provide a track construction method that can rapidly improve the gravel track to a concrete track by solving the problems of the prior art as described above.

Another object of the present invention is to provide a track construction method capable of replacing a gravel track 20m with a concrete track within 4 hours, which is a blocking time for train operation.
