Description

Mortar supply equipment for rapid hardening track to improve gravel track {MORTAR SUPPLYING EQUIPMENT FOR FAST-HARDENING TRACK FOR IMPROVING BALLAST TRACK}

The present invention relates to a mortar supply equipment, and more particularly, to a mortar supply equipment that transports, mixes, and injects mortar in a rapid hardening track construction that improves a railway's gravel track into a concrete track.

In general, it is widely known that a track on which a train or the like runs is provided with a roadbed on a roadbed, and sleepers and rails are disposed on the roadbed. Here, the islands are used as gravel (or crushed stone) or concrete as a track material that widely distributes train loads transmitted from rails and sleepers and transmits them to the roadbed and fixes the sleepers at a predetermined position.

In such a track structure, it is common to arrange sleepers on a road formed on a roadbed, and then attach a pair of rails in parallel at regular intervals. Ballasts, slabs, etc. are selected as the islands constituting the track, and are selected in consideration of various conditions of the route. In particular, ballast island tracks using ballast such as gravel and crushed stone are widely known. These ballasts such as gravel and crushed stone keep the sleepers securely, distribute the load transmitted from the train through the rails and sleepers evenly to the roadbed, make the track elastic, and easily perform repair work such as damping. It has to have a function to prevent drainage or weeds by improving the drainage of the track.

On the other hand, in a railroad infrastructure structure, a traditional gravel track can be constructed quickly, but it requires periodic maintenance because plastic deformation of gravel occurs whenever the load of the train is applied. The track is turning into a concrete track. In other words, the track structure is gradually changing from a gravel track to a concrete slab track along with the recent speedup of trains. For example, when laying a track such as a high-speed rail, the occurrence of track misalignment has become a major problem, and in the case of a general gravel track using gravel, a problem such as scattering of gravel when passing a train has emerged.

In this state, when a mortar (Mortar) stirred toward the regenerated gravel (13) is injected, a mortar filling layer (17) is formed, and the mortar filling layer (17) is cured to complete the rapid concrete track (10).

However, in order to improve the existing gravel track to the rapid concrete track 10, a long working time is required, while the time during which the train is not operated is limited, and thus a technique for increasing the speed of the existing process is required.

In other words, the process of converting a gravel track to a concrete track through the rapid improvement of the gravel track requires complicated steps and requires a long working process, but limited working time after the railroad vehicle operation is finished, for example, about 4 hours. The concrete track that can be completed during the construction has the disadvantage that the construction length is short.
